CCD and WFI are payloads in the visible light and near infrared bands on CBERS satellites and they have not been applied widely, especially WFI. This article mainly probes into the potential of these two sensors’ application in the vegetation monitoring and analyses the influences of radiometric calibration, atmosphere conditions and sun-observing geometry, etc. on NDVI obtained from these two sensors respectively. In addition it analyses the effect of the spectral response difference of red and near infrared spectral bands in CCD and WFI sensors on NDVI. Results indicate that radiometric calibration is the most important factor on NDVI, which cannot be applied to vegetation monitoring without radiometric calibration. Results also demonstrate that near surface NDVI is different greatly from that of TOA which change with atmosphere conditions. The study shows that NDVI is also affected by the non-lambertian character of surface and the change of the atmospheric path with the observing geometry. And NDVI of WFI is higher than that of CCD. They are very different because of their spectral difference, but they have a good linear relevant relationship.

Study　on　the　pathogenetic　effect　of　salted　pork　from　a　high　risk　area　of　stomach　cancer　in　China

引用

World Journal of Gastroenterology 1997年第2期3卷 36-37页

作者： YUAN Yuan 1. LIN Hui Zhi 1. ZHANG Yin Chang 1. WANG Xuan Jie 2, WU Yie Qiu 1. GAO Hua 1. WANG Lan 1. LIU Yan Hou 3, LU Fang 3 and LOU Su Qing 3

AIM To study the pathogenetic effect of salted pork (SP) (special food in Zhuanghe City, a high risk area of stomach cancer in northern China) on stomach cancer, and provide scientific basis for primary prevention of stomach cancer in this high risk area. METHODS The study consisted of three parts. The first part was to study the mutagenicity of SP. The Ames test and micro nuclei assay of V 79 cell were employed in this part. The second part was to study the effect of SP on the gastric mucosa of residents in Zhuanghe area who had consumed SP for more than 1. years and the dose effect relations between SP and pathological changes of gastric mucosa. A total of 300 cases were analysed. The third part was to study the mucosal lesions of experimental dogs by gastroscopy and mucosal biopsy. Six healthy male dogs were chosen, three were fed with SP, and the others served as control. RESULTS In this study, the results showed that the extract of SP could lead to mutation of Salmonella typhimurium TA 98 and induce the increase of micro nuclei rate (MNR) and micro nuclei cell rate (MNCR) of V 79 at a dose range of 20～80μl/ml. There were dose effect relations between SP, MNR, MNCR. Pathological changes of gastric mucosa of local residents who had consumed SP showed significant difference from those of the control group. In people who had consumed SP for 1. years, mucosal lesions including necrosis and erosion were found; in those who consumed SP for 1.～20 years, hyperplasia and dysplasia were also seen besides the above lesions and those for 20～30 years, severe dysplasia and even malignant changes could be observed. SP had damaging effect on the gastric mucosa of dogs fed with SP. The mucosal lesions became more severe with increasing feeding time. CONCLUSION SP is a strong mutagen and long term exposure to SP may result in repeated gastric mucosal damage and repair, and finally leading to severe dysplasia and malignancy.

P2P systems are becoming the dominator of *** systems are typically composed of thousands to millions of physical computers,which make it difficult to predict their behaviors without a large scale distributed system *** paper is an attempt to predict the behavior of large scale P2P systems by building a novel parallel simulator:AegeanSim,which provides parallel discrete event simulation of such systems on high performance server *** abstract the execution of P2P applications with a specific event model,and parallel the simulation of events in a cluster,thus expanding the simulation scale and boosting the simulation process dramatically.A 1.stage synchronization method is proposed to improve the *** event callback interface is designed to implement their application logic easily while keeping the simulator *** use AegeanSim to predict the behavior of a typical P2P system:*** comparing the simulation behavior of BT with that of related BT studies and verifying its efficiency,scalability and accuracy,we make predictions about the behavior of BT system assuming they are assaulted by different man-made system *** reasonable results are found:(1. Tracker isolation can hardly work because of its short attacking time window.(2) Limiting the bandwidth of BT may be an efficient way to control it.

The Reliability Research of the Supply Chain Management Based on the Fuzzy Operation

引用

厦门大学学报（自然科学版） 2002年第S1期41卷 233-页

作者： YAN Xiu-xia 1.2, SUN Lin-yan 1.(1. Management School, Xi’an Jiaotong University, Xi’an 71.049, China 2. Management School, Shandong University of Technology, Zibo 25501., China)

The complex and varied relationships between supply a nd demand among different enterprises calls for an effective way to evaluate and maintain reliability in supply chain management. Individually, enterprises purs ue maximum benefit strategy while cooperating with others. This behavior may res ult in the weakening of needed reliability in supply chain or, in more serious c ases, sever the supply chain. Although reliability of supply chain is the bases to ensuring long-term benefit, a systematic way of handling reliability issues in supply chain management has drawn little attention. The main objective of thi s paper is to define reliability in supply chain management and to develop a fuz zy operational model based on two factors: serial and parallel, to research it.

Is There A Relationship between Polycystic Ovary Syndrome and Endometriosis?

Journal of Reproduction and Contraception 2011年第3期22卷 177-182页

The endocrinologic and metabolic abnormalities of women with polycystic ovary syndrome （PCOS） can result in a series of endometrial diseases. Abnormalities of hyperandrogenism and hyperinsulinemia that may be found in PCOS can elevate the levels of E2 indirectly, reduce progesterone secretion and induce some growth factors such as vascular endothelial growth factor （VEGF） and insulin-like growth factors （IGFs） over expression, which may have a major impact on endometriosis occurrence and development. We suppose that there is a possible connection between PCOS and endometriosis.

The effect of Dzialoshiski-Moriya (DM) interaction on the violation of Bell inequality for thermal states of interacting qubits via a two-qubit XXZ spin chain is *** results imply that the DM interaction and anisotropy taking a large positive value can enhance the Bell violation and improve the threshold temperatures of *** the comparison between the Bell violation and thermal entanglement,we find that the threshold temperatures of thermal entanglement are higher than those of the Bell *** implies that some states are entangled but the Bell inequality is not violated.
