| 1 | 川东“侏罗山式”褶皱的数值模拟及成因探讨显示文摘本文通过采用有限差分法(FLAC)对'侏罗山式'褶皱进行数值模拟发现,层间粘聚力差异和上覆压力是控制隔档式褶皱、隔槽式褶皱样式的主要因素,即层间的能干性差异和埋深的控制。当地层在埋深较浅时,层间能干性差异对褶皱样式起主控作用,能干性差异小时出现隔槽式褶皱,差异大时出现隔档式褶皱。随着埋深加大,压力逐渐起主要作用,这时仅出现隔槽式褶皱。川东东带褶皱地层总体上层间能干性差异小,因而盖层的深部与浅部皆出现隔槽式褶皱,与模拟结果一致。西带褶皱地层总体层间能干性差异大,因而浅部出现隔档式褶皱。而其深部的下古生界地层主要受上覆压力控制,根据模拟推测应为隔槽式褶皱。 | 张必龙 朱光 JIANG Dazhi 胡召齐 向必伟 张力 陈印 | 2009 | 地质论评2009，55，5： | 32 |
| 2 | Deformation characteristics and formation mechanism of the Yunmengshan metamorphic core complex显示文摘The Yunmengshan metamorphic core complex in the middle part of the Yanshan Fold and Thrust Belt records crust extension processes of the eastern North China Craton during its peak destruction.Development of the metamorphic core complex was controlled by the generally NNE-striking Dashuiyu Shear Zone.The shear zone dips SE and becomes shallower NE-wards,leading to exposures of a ductile shear zone in the southern and middle parts and brittle faults in the northern part.Exposure structures,microstructures,and quartz C-axis fabrics indicate that the ductile shear zone belongs to an extensional shear zone with a top-to-the-SE shear sense.Deformation temperatures of 300–520°C suggest a midcrustal origin for the ductile shear zone.A ductile deformation belt in the footwall of the shear zone is only as wide as 1–3 km,indicating no widespread mid-crustal ductile flow in the region during the deformation.Zircon U–Pb dating of dykes and plutons as well as hornblende and biotite40Ar/39Ar dating demonstrate that the metamorphic core complex originated at 135 Ma and experienced intense shearing of the Dashuiyu Shear Zone,development of the supradetachment basins,and synkinematic intrusion during 135–125 Ma.The metamorphic core complex was subjected to rapid exhumation during 125–114 Ma when the Dashuiyu Shear Zone suffered continuous activity and passive doming.The shear zone and its hanging wall were cut or replaced by a series of brittle faults when they wereuplifted to a brittle regime,showing that exhumation took place in continuous extensional activities.The metamorphic core complex turned into slow exhumation in an extensional regime in the following latest Early Cretaceous.The evolution history suggests that the Yunmengshan metamorphic core complex was developed by the rolling-hinge model,a common formation mechanism for intraplate metamorphic core complexes in the North China Craton,under the continuous NW–SE extension during the Early Cretaceous(135–100 Ma). | Yin Chen Guang Zhu Dazhi Jiang Shaoze Lin | 2014 | Chinese Science Bulletin2014，59，20： | 10 |

| 4 | Prognostic value of programmed death.1, programmed death-ligand 1, programmed death-ligand 2 expression, and CD8(+) T cell density in primary tumors and metastatic lymph nodes from patients with stage T1.4N+M0 gastric adenocarcinoma显示文摘Background: Anti-programmed death-1/programmed death-ligand 1(PD-1/PD-L1) immunotherapy has been proved to be effective on gastric cancer in ongoing clinical trials. However, the value of PD-L1 in predicting responses of patients with gastric cancer to anti-PD-1/PD-L1 immunotherapy is controversial. Some studies suggested that intra-and inter-tumoral heterogeneity of PD-L1 expression might explain the controversy.This study aimed to analyze the expression of PD-L1, PD-L2, and PD-1 as well as CD8(+) T-cell density in primary tumors and lymph nodes from patients with stage T1-4 N+M0 gastric adenocarcinoma to explore the heterogeneity of PD-1 signaling pathway molecules.Methods: In primary tumors and metastatic as well as non-metastatic lymph nodes from patients with stage T1-4 N+M0 gastric adenocarcinoma, we detected PD-L1 and PD-L2 expression with immunohistochemistry. CD8(+)T-cell density in primary tumors and PD-1 expression on CD8(+)T cells were detected with immunofluorescence. Univariate analysis was used to determine the prognostic values of them. Cox proportional hazard regression model was used to identify independent risk factors that affect patients' overall survival and disease-free survival.Results: Among 119 eligible patients who had undergone surgical resection, the positive rate of PD-L1 was higher in metastatic lymph nodes than in primary tumors(45.4% vs. 38.7%, P = 0.005); the positive rate of PD-1 on CD8(+)T cells was significantly higher in primary tumors and metastatic lymph nodes than in tumor-free lymph nodes(both P < 0.001). The intensity of PD-1 expression on CD8(+) T cells in primary tumors and in metastatic lymph nodes were stronger than that in tumor-free lymph nodes from the same patient. Beside, the positive rate of PD-L2 did not show any differences between primary tumors and metastatic lymph nodes. In multivariate analysis, PD-L1 expression,PD-L2 expression, a low density of CD8(+) T cells in primary tumors, and PD-1 expression on CD8(+) T cells in primary tumors were associated with poor prognosis.Conclusion: The expression of PD-L1 is heterogeneous in primary tumors and in metastatic lymph nodes from patients with stageT1-4 N+M0 gastric adenocarcinoma, which might explain the inconsistent results in assessing the prognostic value of PD-L1 expression in previous studies. | Yuan Gao Su Li Dazhi Xu Shangxiang Chen Yuchen Cai Wenqi Jiang Xinke Zhang Jin Sun Kefeng Wang Boyang Chang Fenghua Wang Minghuang Hong | 2017 | Chinese Journal of Cancer2017，36，11： | 8 |
| 5 | 剪切带运动学:重点评述三斜模式和区分韧性滑动擦痕与拉伸线理的重要性显示文摘详细评述了剪切带运动学和内部几何学研究的新进展。剪切带内的递进变形一般为三斜对称,单斜剪切带(包括简单剪切带)是特例情形。理论模拟表明,如同许多天然剪切带中所见到的,在三斜剪切带中,拉伸线理的方位可从近水平到平行于倾向连续变化。过去一般将拉伸线理的方向当作剪切运动方向的做法是以简单剪切模式为基础的,不适合于一般剪切带。在三斜剪切带中,拉伸线理和剪切方向之间不存在简单关系。然而,C面上的韧性滑动擦痕平行于剪切方向发育,是剪切方向的可靠标志。因此,在剪切带运动学解释中区分韧性滑动擦痕与拉伸线理非常重要。 | 林寿发 姜大志 Paul F.

| 6 | Dispersion–tribological property relationship in mineral oils containing 2D layered α-zirconium phosphate nanoplatelets显示文摘Inorganic nanomaterials exhibit superior friction-reduction and anti-wear properties in oils. In this study, 2D layered α-zirconium phosphate (α-ZrP) nanosheets intercalated with different amines have been synthesized to study their dispersion stabilities in lubricating oil and tribological applications. The intercalated amines should be sufficiently long and lipophilic to provide stabilization to α-ZrP nanosheets in mineral oil. The results of tribological tests illustrate that with the addition of well-dispersed nanosheets, the coefficient of friction (COF) and pin volume loss reduce by ~47% and 75%, respectively. The excellent dispersion stability enables the nanosheets to flow into the contact area at the beginning, and thereby protect the rubbing surface. A reduction in the van der Waals forces between the adjacent layers induced by the intercalated amines transforms the friction between adjacent layers from pin disk to sliding, leading to a decrease in the COF under hydrodynamic lubrication. The study provides a new method to enhance the tribological properties via tuning the dispersion stabilities of nanomaterials in oils. | Feng JIANG Haoyang SUN Lei CHEN Fan LEI Dazhi SUN | 2020 | Friction2020，8，4： | 3 |
| 7 | 北大别造山后穹隆构造的形成过程与变形模拟显示文摘北大别穹隆是在早白垩世造山后伸展活动中形成的。其北界为北西西走向、倾向北北东、正左行平移的晓天—磨子潭韧性剪切带,南界为北西走向、倾向南东、右行'逆冲'的五河—水吼韧性剪切带。通过对这两条剪切带的构造观测、运动学分析、石英C轴组构测量、变形温度分析及变形模拟,表明剪切带原先为中地壳同一近水平的韧性拆离剪切带。该拆离剪切带在原始近水平状态时的活动为上盘向280°方位的伸展运动。随后在大规模岩浆活动与北大别穹隆的隆升中,这一剪切带被动地抬升与剥露,而出露于现今的穹隆边界上。变形模拟显示,北大别穹隆构造现今为近EW轴向的背形,其上隆幅度西强东弱。北大别穹隆的形成过程表明为典型的造山带变质核杂岩。 | 向必伟 王勇生 Dazhi Jiang 朱光 张必龙 谢成龙 | 2009 | 地学前缘2009，16，3： | 2 |
| 8 | A new DNA algorithm to solve graph coloring problem显示文摘Using a small quantity of DNA molecules and little experimental time to solve complex problems successfully is a goal of DNA computing. Some NP-hard problems have been solved by DNA computing with lower time complexity than conventional computing. However, this advantage often brings higher space complexity and needs a large number of DNA encoding molecules. One example is graph coloring problem. Current DNA algorithms need exponentially increasing DNA encoding strands with the growing of problem size. Here we propose a new DNA algorithm of graph coloring problem based on the proof of four-color theorem. This algorithm has good properties of needing a relatively small number of operations in polynomial time and needing a small number of DNA encoding molecules (we need only 6R DNA encoding molecules if the number of regions in a graph is R). | Jiang Xingpeng Li Yin Meng Ya Meng Dazhi | 2007 | Progress in Natural Science:Materials International2007，17，6： | 2 |
| 9 | The impact of mean dynamic topography on a sea-level anomaly assimilation in the South China Sea based on an eddy-resolving model显示文摘The sea-level anomaly (SLA) from a satellite altimeter has a high accuracy and can be used to improve ocean state estimation by assimilation techniques. However, the lack of an accurate mean dynamic topography (MDT) is still a bothersome issue in an ocean data assimilation. The previous studies showed that the errors in MDT have significant impacts on assimilation results, especially on the time-mean components of ocean states and on the time variant parts of states via nonlinear ocean dynamics. The temporal-spatial differences of three MDTs and their impacts on the SLA analysis are focused on in the South China Sea (SCS). The theoretical analysis shows that even for linear models, the errors in MDT have impacts on the SLA analysis using a sequential data assimilation scheme. Assimilation experiments, based on EnOI scheme and HYCOM, with three MDTs from July 2003 to June 2004 also show that the SLA assimilation is very sensitive to the choice of different MDTs in the SCS with obvious differences between the experimental results and observations in the centre of the SCS and in the vicinity of the Philippine Islands. A new MDT for assimilation of SLA data in the SCS was proposed. The results from the assimilation experiment with this new MDT show a marked reduction (increase) in the RMSEs (correlation coefficient) between the experimental and observed SLA. Furthermore, the subsurface temperature field is also improved with this new MDT in the SCS. | XU Dazhi ZHU Jiang QI Yiquan LI Xichen YAN Youfang | 2012 | Acta Oceanologica Sinica2012，31，5： | 2 |

| 16 | Metamorphism and geochronology of garnet amphibolite from the Beishan Orogen,southern Central Asian Orogenic Belt:Constraints from P-T path and zircon U-Pb dating显示文摘Numerous lenses of garnet amphibolite occur in the garnet-bearing biotite-plagioclase gneiss belt in the Baishan area of the Beishan Orogen,which connects the Tianshan Orogen to the west and the Mongolia-Xing’anling Orogen to the east.The study of metamorphism in Beishan area is of great significance to explain the tectonic evolution of Beishan orogen.According to the microstructures,mineral relationships,and geothermobarometry,we identified four stages of mineral assemblages from the garnet amphibolite sample:(1) a pre-peak stage,which is recorded by the cores of garnet together with core-inclusions of plagioclase(Pl1);(2) a peak stage,which is recorded by the mantles of garnet together with mantle-inclusions of plagioclase(Pl2)+amphibole(Amp1)+Ilmenite(Ilm1)+biotite(Bt1),developed at temperature-pressure(P-T) conditions of 818.9-836.5℃ and7.3-9.2 kbar;(3) a retrograde stage,which is recorded by garnet rims + plagioclase(Pl3)+amphibole(Amp2)+orthopyroxene(Opx1)+biotite(Bt2)+Ilmenite(Ilm2),developed at P-T conditions of 796.1-836.9℃ and5.6-7.5 kbar;(4) a symplectitic stage,which is recorded by plagioclase(Pl4)+orthopyroxene(Opx2)+amphibole(Amp3)+biotite(Bt3) symplectites,developed at P-T conditions of 732 ±59.6℃ and 6.1 ±0.6 kbar.Moreover,the U-Pb dating of the Beishan garnet amphibolite indicates an age of 301.9 ±4.7 Ma for the protolith and 281.4±8.5 Ma for the peak metamorphic age.Therefore,the mineral assemblage,P-T conditions,and zircon U-Pb ages of the Beishan garnet amphibolite define a near-isothermal decompression of a clockwise P-T-t(Pressure-Temperature-time) path,indicating the presence of over thickened continental crust in the Huaniushan arc until the Early Permian,then the southern Beishan area underwent a process of thinning of the continental crust. | Wenbin Kang Wei Li Lei Kang Yunpeng Dong Dazhi Jiang Jiwei Liang Haoqiang Dong | 2020 | Geoscience Frontiers2020，11，4： | 0 |
| 17 | New Zircon U-Pb Ages of the Shirenshan Gneiss, North Qinling and Their Geological Implications显示文摘The Qinling Orogenic Belt(QOB)is a composite continental orogenic belt that has experienced many tectonic events.The QOB is subdivided into the following three litho-tectonic units:the North Qinling terrane,the Middle Qinling microplate and the South Qinling terrane.The North Qinling Terrane(NQT)underwent destruction and lithospheric thinning during the late Mesozoic,accompanied by extensive magmatic activity and increased surface heat flux,led to large-scale tectonic extension(e.g.,Ren Shenglian et al.,2016).The Shirenshan gneiss is located along the contact between the NQT and the North China Block(Fig.1).Previous studies suggested that it was produced as a result of the northward subduction of the NQT beneath the North China Block(e.g.,Wang Jingya et al.,2017).Therefore,it is significant to study its structural geology,petrology,geochemistry and chronology in order to understand the tectonic settings and the interaction between the Middle Qinling microplate and the North China Block. | WANG Jingya REN Shenglian JIANG Dazhi DONG Shuwen LI Jiahao LI Longming GE Can SONG Chuanzhong HAN Xu LI Zhenqiang | 2019 | Acta Geologica Sinica(English Edition)2019，93，1： | 0 |
| 18 | A STUDY OF FRACTURE OF UNIDIRECTIONAL CF/SiC SINGLE EDGE-NOTCHED BEAM UNDER THREE-POINT BENDING- MACRO/MICRO-NUMERICAL MONTE CARLO SIMULATION显示文摘In this paper, the fracture process of a unidirectional CF/SiC single edge-notched beam (SENB) under three-point bending (TPB) is studied by means of macro/micro-statistical Monte Carlo simulation. The simulated p-△ curves are in agreement with the experimental results before the peaks of curves, and the simulated microevolution patterns are in agreement with the patterns of the crack surfaces, which have verified this method. It is preliminarily demonstrated that the second turning point in the compliance changing rate curve corresponds to the fracture initiation for experiments on SENB under TPB of unidirectional CF/SiC composites. | Wang Yang Cheng Tianle Xia Yuanming Jiang Dazhi | 2001 | Acta Mechanica Solida Sinica2001，14，1： | 0 |
| 19 | An Evolutionary Adaptive System for Prediction of Strategy Influence:A Case Study of Government Regulation Guided Brand Innovation显示文摘Decision making is one of the common human activities.But in complex,interactive,and dynamic systems,it is extremely important to make decisions scientifically because the influence of the behavior after decision making is generally irreversible.The predictability of behavior influence is an effective way to improve the scientific decision making.As a new branch of computing,computational experiment is an emerging management method for research on complex systems.In this paper,based on particle swarm intelligence,an evolutionary adaptive system model of brand innovation in the toy industry cluster is constructed.By imitating the evolution process of the complex adaptive system,this method is helpful to analyze the impact of the management behavior brought to simulation system,predict the management behavior in real world,and finally choose the best management strategy.This simulation tried to figure out the affection of government regulation strategies and provide corresponding assessments and recommendations,which gives a new solution to assist the government to effectively judge the influence of the macro policy,as well as provides a new way of thinking of the related intelligent decision making. | Jiali Lin Qiaomei Li Guangsheng Lin Zhihui He Dazhi Jiang Hao Liu | 2022 | Complex System Modeling and Simulation2022，2，3： | 0 |
| 20 | Two-Dimensional Images of Current and Active Power Signals for Elevator Condition Recognition显示文摘In this paper, an improved two-dimensional convolution neural network(2DCNN) is proposed to monitor and analyze elevator health, based on the distribution characteristics of elevator time series data in two-dimensional images. The current and effective power signals from an elevator traction machine are collected to generate gray-scale binary images. The improved two-dimensional convolution neural network is used to extract deep features from the images for classification, so as to recognize the elevator working conditions. Furthermore, the oscillation criterion is proposed to describe and analyze the active power oscillations. The current and active power are used to synchronously describe the working condition of the elevator, which can explain the co-occurrence state and potential relationship of elevator data. Based on the improved integration of local features of the time series, the recognition accuracy of the proposed 2DCNN is 97.78%, which is better than that of a one-dimensional convolution neural network. This research can improve the real-time monitoring and visual analysis performance of the elevator maintenance personnel, as well as improve their work efficiency. | Xunsheng Ji Dazhi Wang Kun Jiang | 2023 | Journal of Harbin Institute of Technology(New Series)2023，30，2： | 0 |
