| 1 | Raman spectra and structure study of silicate glasses and their liquids显示文摘Stress index of tetrahedron (SIT) was defined to describe the topological connectivities among various sili- con-oxygen tetrahedra (SiOT) in anionic clusters of binary silicate crystals, glasses, and melts. It was found that the value of SIT was well correlated with the wavenumber of Raman active symmetric stretching vibration of non-bridging oxygen of SiOT. The spatial fractional dimension of hyperfine structure was introduced while comparative analysis was made with the value of SIT. It can be concluded that the concepts of SIT, vibrational wavenumber, and spatial fractional dimension were inherently and holographically correlated and exhibit isomorphic representations of complex structure of binary silicates. Experimental Raman spectra of binary silicates with different alkali cations were investigated. It was demonstrated that al- kali cations have little effect on the vibrational wavenumber of symmetric stretching of non-bridging oxygen (NBO) of SiOT, but remarkably affect its Raman active optical cross section, as was consensus resulted from ab initio calculation. It can also be concluded that the spatial fractional dimension of binary silicate is predominantly determined by the hyperfine structure of the anionic clusters and little affected by alkali cations, although the species of anionic clusters and their distri- butions were originally assigned by the content of alkali oxides. And Raman optical activity extinct effect of isolated SiOT at high basicity should be considered while being applied to quantitatively analysis. | YOU Jinglin JiANG Guochang CHEN Hui XU Kuangdi | 2006 | Rare Metals2006，25，5： | 4 |
| 2 | Estimation of stature by using the dimensions of the right hand and right foot in Han Chinese adults显示文摘The Han Chinese people are the main ethnic group in China and the largest ethnic group in the world.The dimensions of the hands and feet have been successfully used for the estimation of stature.A total of 26,927 healthy adult subjects,comprising 13,221 men and 13,706 women,were recruited.The survey samples were chosen through random cluster sampling.The mean values were significantly higher in men than those in women for all measurements(P<0.001).All the measurements showed a statistically significant correlation with stature(P<0.01).The combination of the right hand length and the right foot length was the best predictor of stature because it had the lowest standard error of estimate.The use of multiple regression equations yielded better results than did the use of linear regression equations.The accuracy of stature prediction ranged from ±4.81 to ±6.39 cm.The present study was of great importance with regards to improving the physical anthropology database of ethnic groups in China. | Xinghua Zhangi Yu Wei Lianbin Zhengi Keli Yu Dapeng Zhao Jinping Bao Yonglan Li Shunhua Lu Huanjiu Xi Guochang Xu Youfeng Wen | 2017 | Science China(Life Sciences)2017，60，1： | 4 |
| 3 | Orbit determination and thrust force modeling for a maneuvered GEO satellite using two-way adaptive Kalman filtering显示文摘A two-way adaptive Kalman filter is proposed by combining a two-way filter with an adaptive filter for orbit determination of a maneuvered GEO satellite.A method of using Newton's high-resolution differential formula and polynomial fitting for modeling the thrust force of a maneuvered GEO satellite is developed.The adaptive factor,which balances the contributions of the measurements and the dynamic model information,is determined by using a two-segment function and predicted residual statistics.Simulations with a maneuvered GEO satellite tracked by the Chinese ground tracking network were conducted to verify the performance of the proposed orbit determination technique and the method of thrust force modeling.The results show that refining the thrust force model is beneficial for the orbit determination of a maneuvered GEO satellite;the two-way adaptive Kalman filter can efficiently control the influence of the dynamic model errors on the orbit state estimate. | XU TianHe HE KaiFei XU GuoChang | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，4： | 2 |

| 18 | KINETICS OF DESULPHURIZATION IN PERMANENT CONTACT OF SLAG AND STEEL显示文摘The curve of % S vs reaction time is described quantitatively based on the electrochemicalmodel directly deduced from the principle of electrochemistry as well as the given method forcalculating the initial oxygen potential along slag/steel interface.The calculated data is ingood agreement with the experimental results.During desulphurization,both L_s~* and L_s,the sulphur partition along the interface andthat in the bulk,go up in association with the descending of oxygen potential along interface.The plot of L_s~* against reaction time follows a parabolic curve,while that of L_s is ofhyperbola type.Correspondingly,on curves of driving force parameter vs reaction tone,eithercalculated or experimental,a hump occurs. | JIANG Guochang XU Kuangdi DENG Jianxiong Shanghai University of Technology,Shanghai,ChinaGUO Zhancheng GUAN Yulong Beiiing University of Science and Technology,Beijing,China Jiang Guochang Associate Professor,The Institute of Metallurgy and Materials,Shanghai University of Technology,Shanghai 200072,China | 1990 | Acta Metallurgica Sinica(English Letters)1990，3，10： | 1 |
| 19 | Prediction rule for estimating advanced colorectal neoplasm risk in average-risk populations in southern Jiangsu Province显示文摘Objective:The aim of this study was to establish the risk scoring system towards the advanced colorectal neoplasm(CN) risk in the average-risk populations in the southern Jiangsu Province,and to evaluate the screening efficacy.Methods:Totally 905 cases of the average-risk populations who received the colonoscopy were selected as the objective.The multivariate logistic regression analysis method was used to establish the scoring system towards the occurrence risk of the advanced tumor,and its screening efficacy was evaluated through the prediction consistency,distinguishing ability and screening accuracy.Results:The scoring system consisted of five variables,namely age,gender,coronary heart disease,egg intake and stool frequency.The results revealed that it had good prediction consistency(P=0.205) and distinguishing ability [the area under the receiver operating characteristic(ROC) curve was 0.75,with 95% confidence interval(95% CI) of 0.69-0.82].Thus,2.5 points was set as the screening cutoff value,and its sensitivity,specificity,accuracy,positive predictive value,negative predictive value,positive likelihood ratio and negative likelihood ratio were 93.8 %,47.6%,50.1%,9.1%,99.3%,1.79 and 0.13,respectively.Conclusions:The established scoring system had good screening efficacy,and can be used as the screening tool applying to the CN screening within the average-risk populations in the southern Jiangsu Province. | Guochang Chen Boneng Mao Qi Pan Qian Liu Xinfang Xu Yueji Ning | 2014 | Chinese Journal of Cancer Research2014，26，1： | 1 |
