There are more than forty pieces of materials related to Sima Xiangru and Zhuo Wen-jun. These materials roughly draw the the character of Sima Xiangru in the Song people's eyes by expatiating on the following aspects the mind of him, the style of his literature. the relationship of his literature and the literature of other dynasties. In Song Dynasty, the comments on Sima Xiangru not only inherited the early views, but also have something new which shows the unique digestion when the Song people studied Sima Xiangru From this we can also see that the different aesthetic preferance and literatural values among the Song scholars. So, an anaylsis on these materials about Sima Xiangru in Song ShiHua can help us to better understand and accept him.Song ShiHua, Sima Xiangru, BaiTouyin, mind and action, Song of Chu, shi, satirize 宋诗话中涉及司马相如和卓文君的材料多达四十则左右,这些材料分别对司马相如的思想行为,司马相如作品的风格,司马相如作品与历代文学的关系等几个方面作了较为详尽地阐述,粗略勾勒了宋人眼中的司马相如。在宋代,对司马相如的评价不但对前代的观点有所继承,发挥或补充修正,更有一些新的见解,表现出宋代文人研习司马相如的独特体会和心得,亦可见出宋代文人不同于前代的审美取向和文学价值观,因此,对宋诗话中与司马相如有关的材料作疏理,可以帮助我们了解宋人对司马相如的认识和接受。

Aims: Hepatocellular carcinoma (HCC) is a leading cause of cancer-related deaths worldwide. The metabolic biochemical pathway disturbances associated with HCC progression and recurrence remain unsatisfactorily characterized. Dysregulated metabolism is a hallmark of cancer including HCC, manifested through alterations in metabolites. The emerging field of me tabolomics has increased the hope of discovering metabolites and biochemical pathways as the novel biomarkers or thera peutic targets of HCC and tracking tumor recurrence. Methods: Metabolomic profiling was conducted with the Metabolon platform for one hundred and twenty human recur rent/non-recurrent HCC tumor/normal paired tissues. Standard statistical analyses are performed in the Partek Genomics Suite on log transformed data. Principal component analysis (PCA) was conducted using all and dysregulated metabolites. Random Forest classification was applied to compare tumor vs. adjacent margin tissues and recurrent vs. non-recurrent tumors using named metabolites. Results: We found that HCC recurrence is characterized by increasing glycolysis and glutaminolysis. Tumor recurrence was significantly associated with increasing of glucose, pyruvate, α-ketoglutarate and NAD+/NADH metabolites to increase gly colysis and glutaminolysis. Higher acylcarnitine levels in non-re current HCC indicate elevated fatty acid β-oxidation. Besides, we also found that Coenzyme A levels were higher and plas malogen lipids were uniformly lower in recurrent HCC. Conclusions: Our study generates a comprehensive metabolo mics dataset on HCC and highlight the massive reorganization of cellular metabolism as tumors progress and acquire recur rence feature.

Combined Static and Dynamic Platform Calibration for an Aerial Multi-Camera System
( Hong-xia Cui ),( Jia-qi Liu ),( Guo-zhong Su ) 한국인터넷정보학회 2016 KSII Transactions on Internet and Information Syst Vol.10 No.6
Multi-camera systems which integrate two or more low-cost digital cameras are adopted to reach higher ground coverage and improve the base-height ratio in low altitude remote sensing. To guarantee accurate multi-camera integration, the geometric relationship among cameras must be determined through platform calibration techniques. This paper proposed a combined two-step platform calibration method. In the first step, the static platform calibration was conducted based on the stable relative orientation constraint and convergent conditions among cameras in static environments. In the second step, a dynamic platform self-calibration approach was proposed based on not only tie points but also straight lines in order to correct the small change of the relative relationship among cameras during dynamic flight. Experiments based on the proposed two-step platform calibration method were carried out with terrestrial and aerial images from a multi-camera system combined with four consumer-grade digital cameras onboard an unmanned aerial vehicle. The experimental results have shown that the proposed platform calibration approach is able to compensate the varied relative relationship during flight, acquiring the mosaicing accuracy of virtual images smaller than 0.5pixel. The proposed approach can be extended for calibrating other low-cost multi-camera system without rigorously mechanical structure.

Ultimate capacity of welded box section columns with slender plate elements
Hong-Xia Shen 국제구조공학회 2012 Steel and Composite Structures, An International J Vol.13 No.1
For an axially loaded box-shaped member, the width-to-thickness ratio of the plate elements preferably should not be greater than 40 for Q235 steel grades in accordance with the Chinese code GB50017- 2003. However, in practical engineering the plate width-to-thickness ratio is up to 120, much more than the limiting value. In this paper, a 3D nonlinear finite element model is developed that accounts for both geometrical imperfections and residual stresses and the ultimate capacity of welded built-up box columns,with larger width-to-thickness ratios of 60, 70, 80, and 100, is simulated. At the same time, the interaction buckling strength of these members is determined using the effective width method recommended in the Chinese code GB50018-2002, Eurocode 3 EN1993-1 and American standard ANSI/AISC 360-10 and the direct strength method developed in recent years. The studies show that the finite element model proposed can simulate the behavior of nonlinear buckling of axially loaded box-shaped members very well. The width-tothickness ratio of the plate elements in welded box section columns can be enlarged up to 100 for Q235 steel grades. Good agreements are observed between the results obtained from the FEM and direct strength method. The modified direct strength method provides a better estimation of the column strength compared to the direct strength method over the full range of plate width-to-thickness ratio. The Chinese code and Eurocode 3 are overly conservative prediction of column capacity while the American standard provides a better prediction and is slightly conservative for b/t = 60. Therefore, it is suggested that the modified direct strength method should be adopted when revising the Chinese code.

COMPREHENSIVE ASSESSMENT MODEL OF ECOLOGICAL RIPARIAN ZONE
Xia, Ji-Hong,Wu, Wei,Yan, Zhong-Min Korea Water Resources Association 2005 Water engineering research Vol.6 No.4
Comprehensive assessment of ecological riparian zone is to analyze and evaluate the status of riparian zone ecosystem. The existing problem of the ecosystem can be found through the assessment. The AHP-FUZZY method used in the assessment is based on the hierarchy model of index, grade model of object, and attribution degree of index. Accordingly, the four models have been discussed and presented from the aspect of the stability, landscape, eco-health and eco-safety of riparian zone.

Glass-ceramic glazes have been prepared successfully via crystallization from blast-furnace slag (BFS), fly ash (FA) fluxed with potash feldspar and borax. The crystalline behavior of glass-ceramic glazes was investigated using differential thermal analysis and thermogravimetric analysis (DTA/TG), X-ray diffraction (XRD) and scanning electron microscopy (SEM). Results revealed that the major crystalline phases are anorthite (CaAl2Si2O8) and akermanite (Ca2MgSi2O7) and crystalline phases disperse well in glassy phases with a uniform size of 1 μm. Glass-ceramic glazes possess low density, low water absorption,perfect stain resistance, acid resistance and alkali resistance. The thermal expansion coefficient of glass-ceramic glazes is steady up to 800 oC with an average value of 7.2 × 10−6 /K. Final results suggest that BFS and FA have potential to be vitrified into economically and environmentally low-cost glass-ceramic glaze materials.

Hong-Xia Shen 국제구조공학회 2014 Steel and Composite Structures, An International J Vol.17 No.4
The ultimate carrying capacity of axially loaded welded square box section members made of medium and high strength steels (nominal yield stresses varying from 345 MPa to 460 MPa), with large width-to-thickness ratios ranging from 35 to 70, is analyzed by finite element method (FEM). At the same time, the numerical results are compared with the predicted results using Direct Strength Method (DSM), modified DSM and Effective Yield Strength Method (EYSM). It shows that curve a, rather than curve b recommended in Code for design of steel structures GB50017-2003, should be used to check the local-overall interaction buckling strength of welded square section columns fabricated from medium and high strength steels when using DSM, modified DSM and EYSM. Despite all this, EYSM is conservative. Compared to EYSM and modified DSM, DSM provides a better prediction of the ultimate capacities of welded square box compression members with large width-thickness ratios over a wide range of width-thickness ratios, slenderness ratios and steel grades. However, for high strength steels (nominal yield strength greater than 460 MPa), the numerical and existent experimental results indicate that DSM overestimates the load-carrying capacities of the columns with width-thickness ratio smaller than 45 and slenderness ratio less than 80. Further, for the purpose of making it suitable for a wider scope, DSM has been modified (called proposed modified DSM). The proposed modified DSM is in excellent agreement with the numerical and existing experimental results.
