| 1 | Novel Method for Spatial Angle Measurement Based on Rotating Planar Laser Beams显示文摘Spatial angle measurement,especially the measurement of horizontal and vertical angle,is a basic method used for industrial large-scale coordinate measurement.As main equipments in use,both theodolites and laser trackers can provide very high accuracy for spatial angle measurement.However,their industrial applications are limited by low level of automation and poor parallelism.For the purpose of improving measurement efficiency,a lot of studies have been conducted and several alternative methods have been proposed.Unfortunately,all these means are either low precision or too expensive.In this paper,a novel method of spatial angle measurement based on two rotating planar laser beams is proposed and demonstrated.Photoelectric receivers placed on measured points are used to receive the rotating planner laser signals transmitted by laser transmitters.The scanning time intervals of laser planes were measured,and then measured point's horizontal/vertical angles can be calculated.Laser plane's angle parameters are utilized to establish the abstract geometric model of transmitter.Calculating formulas of receiver's horizontal/vertical angles have been derived.Measurement equations' solvability conditions and judgment method of imaginary solutions are also presented after analyzing.Proposed method for spatial angle measurement is experimentally verified through a platform consisting of one laser transmitter and one optical receiver.The transmitters used in new method are only responsible for providing rotating light plane signals carrying angle information.Receivers automatically measure scanning time of laser planes and upload data to the workstation to calculate horizontal angle and vertical angle.Simultaneous measurement of multiple receivers can be realized since there is no human intervention in measurement process.Spatial angle measurement result indicates that the repeatable accuracy of new method is better than 10'.Proposed method can improve measurement's automation degree and speed while ensuring measurement accuracy. | YANG Linghui YANG Xueyou ZHU Jigui DUAN Muqiong LAO Dabao | 2010 | Chinese Journal of Mechanical Engineering2010，23，6： | 18 |

| 4 | Experimental Study on Concrete Columns Confined by BFRP-PVC Tubes Under Uniaxial Loading显示文摘This paper presents an experimental study on the behavior of circular concrete columns reinforced by BFRP-PVC tubes under uniaxial loading.A total of six specimens were prepared and tested under uniaxial loading.The main parameters varied in the tests were strengthening ratio and strengthening approach of BFRP.The performance,such as failure modes,ultimate bearing capacity and stress-strain curves,was investigated in details and a formula was proposed to predict the compressive ultimate strength.The results show that this kind of confined columns obviously improves the ultimate bearing capacity,and the ultimate bearing capacity increases with the strengthening layers.The formula proposed is applicable and efficient for prediction of the ultimate bearing capacity as well. | 姜绍飞 DAI Tianjie FU Dabao WU Zhaoqi LINing | 2012 | 沈阳建筑大学学报(自然科学版)2012，28，1： | 1 |

| 17 | Large-scale identification of expression quantitative trait loci in Arabidopsis reveals novel candidate regulators of immune responses and other processes显示文摘The extensive phenotypic diversity within natural populations of Arabidopsis is associated with differences in gene expression.Transcript levels can be considered as in-heritable quantitative traits,and used to map expression quantitative trait loci(eQTL)in genome-wide association studies(GWASs).In order to identify putative genetic de-terminants for variations in gene expression,we used pub-licly available genomic and transcript variation data from 665 Arabidopsis accessions and applied the single nucleotide polymorphism-set(Sequence)Kernel Association Test(SKAT)method for the identification of eQTL.Moreover,we used the penalized orthogonal-components regression(POCRE)method to increase the power of statistical tests.Then,gene annotations were used as test units to identify genes that are associated with natural variations in transcript accumulation,which correspond to candidate regulators,some of which may have a broad impact on gene ex-pression.Besides increasing the chances to identify real as-sociations,the analysis using POCRE and SKAT significantly reduced the computational cost required to analyze large datasets.As a proof of concept,we used this approach to identify eQTL that represent novel candidate regulators of immune responses.The versatility of this approach allows its application to any process that is subjected to natural var-iation among Arabidopsis accessions. | Xingang Wang Min Ren Danni Liu Dabao Zhang Cuijun Zhang Zhaobo Lang Alberto PMacho Min Zhang Jian-Kang Zhu | 2020 | Journal of Integrative Plant Biology2020，62，10： | 0 |
