Based on geomorphy and anthropo-factor that influence land use structure, D and S of 8 types is analyzed, and the result indicate that:(1) the complicated geomorphy is uppermost factor that influence fractal dimension of land use type;(2) the social economical level influence D and S of land use structure in a certain extent;(3) the average fractal dimension values and average stability indexes are integrative reflection of the land use structure of each region.

结果表明：(1)复杂的地貌类型是影响土地利用类型D 值和S值的最主要因素；(2)社会经济发展水平一定程度上影响土地利用类型的分维值和稳定性指数；(3)区域土地利用类型的平均分维值、稳定性指数的大小是土地利用结构的综合反映。

Part 2. Measurement of macular light sensitivity and FM 100-hue test in normal prese- nium and geratic people. The macular light sensitivity 、macular foveal light sensitivi- ty in 64 (82 eyes) and hue discrimination in 75 (100 eyes) normal presenium and geratic people were examined with macular threshold (white、red、blue and green color light) program of the Humphreh Field Analyzer and FM 100-hue test respectivity. The re- sults showed that the light sensitivity in four color light threshold was all declined with age. The mean error score square of each spectral region and whole spectral was increased with age, the loss of light sensitivity and hue discrmination was a linear correlated with age. The light sensitivity of the different field was compared, except blue color light threshold, the light sensitivity was decreased with the increasing of the eccentricity, white and red color light threshold in the inferior field showed lower sensitivity than that in the superior field.

Methods: On single-plane and biplane DSA images (including cases with normal ventricular wall motion,hypokinesia and insufficient mixing of contrast medium in ventricular cavity) the area-length method and videodensitometry method were used to calculate the volume and EF respectively.

结果：双向造影的长度-面积法EF测量值与实际值无显著性差异(P＞0.05)；单向造影的测量值在局部室壁运动减弱时差异显著(P＜0.01)；视频密度测量法在室腔内造影剂混合不均时测量值有显著差异(P＜0.01)。

Each group of rats was kept in a separate cage. All of the rats drank water freely and were fed on stand food for rats.The experiment lasted 4 weeks. Indexes to be examined are as follows:⑴spleen T lymphocyte transform value,⑵spleen NK cell activation alternation value,⑶abdominal cavity macrophagocyte IL-1 and IL-2 activation alternation value.

所有动物分笼饲养，各组均自由饮水，喂食标准鼠类饲料，实验时间为4周。4周后，ME组和FE组作一次性力竭游泳运动后和其他各组大鼠股动脉放血处死，留取血清，无菌取胸腺和脾脏，行以下指标检测：⑴脾脏T淋巴细胞转化值；⑵脾脏NK细胞毒活性的变化值；⑶腹腔巨噬细胞IL-1的活性变化值和脾脏分泌的IL-2的活性变化值。

Value at Risk was main tool of market risk management but traditional VaR did not appreciate liquidity risk to make that VaR did not give correct information and was misvalue VaR to lead a large number of damages.

摘要 风险值为现今主要风险管理下之衡量工具，但在传统的风险值模型中，并不重视流动性风险，使得风险值无法提供投资者真实的资讯，另外可能因错估风险值，而造成更大的损失。

Abundances of compatible and weakly incompatible elements in melt vary greatly when P values chanse, so P values of these elementscan not be replaced by D0 in the melting model. However, abundances of moderately and highly incompatible elements only show small variation when P values are different. It is thoughtthat P values of moderately and highly incompatible elements are equal to D0 values in the nonmodal partial melting model.

当P值不同时，相容元素和弱不相容元素在熔体中的浓度出现大的变化，因此，在模型中这些元素的P值不能用D0代替；然而，P值的变化仅造成强不相容及中等不相容元素的浓度小的变化，可以认为强不相容与中等不相容元素的P值约等于D0。

母鸡在开产前第2—12天，血浆LH值低于开产后第3—13天的血浆LH值，但母鸡在开产前第2—12天，血浆雌二醇值则高于开产后第3—13天的血浆雌二醇值。

Based on having read a great deal of literatures about economic threshold, the authors pointed out the necessity and importance for applying the method of economic threshold in the studies of Phyllostachys pubescens ecosystem in this paper, and the authors also put forward the concept of economic threshold of Phyllostachys pubescens ecosystem and its research frame and some problems which should be pay attention to.

The results of the ability of anti-oxidation scavenging DPPH free radical shows that polyhydroxy substituted N-benzoylserotonin derivatives (compound 1-10) have the generally better ability of anti-oxidation than control group, in which the IC50 of compound 1-10 ranges 8.75 to 18.02 μg/ml and the IC50 of trolox is 13.04 μg/ml. The abilities of anti-oxidation of compound 1, 4, 5, 7, and 10 are all better than the control group, trolox. Among all, compound 10 has the best ability of anti-oxidation (IC50 is 8.75 μg/ml). This study also discovers that the ability of scavenging DPPH free radical is strongly related to the number and the position of hydroxyl.

在清除DPPH自由基的抗氧化能力结果显示，相较於对照组水溶性维生素E之IC50值13.04 μg/ml，多羟基取代之N-色洛冬宁苯甲醯胺衍生物（化合物 1 ~ 10），皆具有相当不错的抗氧化能力，十种醯胺化合物的 IC50值介於8.75 ~ 18.02 μg/ml之间，化合物1、4、5、7、10的抗氧化能力效果皆优於对照组水溶性维生素E的IC50值，其中又以化合物10的效果最佳(IC50值8.75 μg/ml)，而清除DPPH自由基的能力发现与羟基的数量及其位置有关。

The split between the two groups can hardly be papered over.
