During the first part, investigate the numbers and location of the different nature reserve, and review about its development, discuss the cause about the rapid developmeng about the protection areas of nature around Beijing. During the second part, this paper use the Geographical Information System to analyze the different sight function, plot our distinct function about the protection area of nature around Beijing. In the third part of this paper, the ecology function was special analyzed. This paper picked up several factor about the ecology and establish mathematics model to detect the most rational ecology distribution, bring forward the new constructive, wilder constructive and combination project. In the last parts of the paper, this paper use the Geographical Information System to analyze the different brim about the protection area of nature around Beijing, calculating the p/a and figure coefficient, and bring forward the brim theory for the nature reserve and city system.

The immunodulatory effects were measured by clearance rate K of charcoal particles, phagocytic index a, thymus and spleen index, ear swelling degree, HC50 value and so on.

方法环磷酰胺诱导小鼠免疫功能低下，予金橘黄酮，观察小鼠碳粒廓清指数K、吞噬指数a、胸腺和脾脏指数、耳肿胀度、血清溶血值（HC50）等指标的变化。

Three-factor Jensen model reveals that 82% of all the funds have positive alphas and half of these alphas are statistically significant. And also, the average of the sample funds' alphas and the alpha of the equal-weighted fund are both positive and statistically significant. These illustrate that the sample funds have excellent performance when size and style factors are considered.(4) The study shows that Chinese funds as a whole do not exhibit excellent skills for stock selection and market timing.

在三因素模型下，有82％的基金的詹森阿尔法大于零，正值詹森指数中的一半具有统计显著性，样本基金詹森指数均值及等权基金的詹森指数均为正值，且具有统计显著性，说明在考虑了规模和价值因素的影响后，样本基金表现优异；（4）对基金选股与择时能力的实证分析表明，中国基金在整体上没有显示出良好的预测市场走势的能力，也未显示出优异的选股能力。

After three years' spring fishing off, dominances of the main species decreased, CPUE of part reaches increased, and Margalef diverdity index, Pielou evenness index and Wilhm Modified Shannon-Wiener diversity index of the three reaches showed the rising tendency, which indicated the richness of species number and complication of community structure, and the positive ecological effects by the spring fishing off.

春禁后，渔获物主要种类优势度有所下降，部分江段单位捕捞努力量渔获量表现出一定上升趋势，3个江段Margalef指数、Pielou指数和Wilhm改进指数有一定升高，表明种类丰富度有所提高，群落结构趋于复杂，春季禁渔有一定效果。

Results: The peak responses of postprandial glucose and C-peptide were postponed; their values and the incremental area under curve of glucose responses of gruels were obviously lower than that of steamed bun (P.05). While both glycemic index and C-peptide index of steamed bun were set as 100, the glycemic index and C-peptide index of gruel A were 67, 99, and of gruel B were 57, 97 in NIDDM patients, 53, 69 in healthy subject.

结果 1。三组餐后血糖、C肽峰值显著低于馒头，血糖反应增值面积有显著性差异，以C组最低，A组最高；2.A、B两组C肽曲线增值面积显著低于C组；3.A、B、C三组血糖、C肽指数分别为67、99，57、97和53、69；4.B、C组血糖指数显著低于A组，C组的C肽指数明显低于A、B组。

In order to make the uncertainty of the dose index measurement in the head phantom reasonable for the medical diagnostic X-ray radiation sources of the computed tomography, the measurement uncertainty components were analyzed according to the mathematical model for the computed tomography dose index test method with a 100 mm ionization chamber.

摘 要：为了使医用诊断计算机断层摄影装置X射线辐射源在模体中的剂量指数测量结果的不确定度评定合理，基于用带有100 mm长杆电离室的积分剂量仪测量CT剂量指数的数学模型，对其测量不确定度来源进行分析，列出了方差、灵敏系数及标准不确定度的计算公式，从而给出了CT剂量指数测量的合成标准不确定度和扩展不确定度。

At the mean time, the article computes the intra-industry trade index of manufacturing sector between China and developed countries and between China and developing countries, analyzing the current situation and pointing out the potentials in development and ways to improve China's intra-industry trade in manufacturing.

第6类轻纺产品、橡胶制品矿冶产品及其制品和第7类机械及运输设备的产业内贸易指数要高于我国制成品的总产业内贸易指数。各类产品中，机械及运输设备的产业内贸易指数最高。

On the landscape level, the regional landscape heterogeneity is increased and the connectivity reduced, which presents the increase of Shannon's diversity index and Evenness Index, decrease of dominance index and increase of fragmentation index. On the class level, it shows that human disturbance on landscape is intense during the past five years, anti the disturbance to artificial landscape mote intense luau that on semi-natural landscape, which means that the fragmentation index of semi-natural landscape is relatively smaller while that of the artificial landscape is larger.

从景观水平上看，区域景观异质性在增大，景观斑块的连通性降低，表现为多样性指数和均匀度指数呈增加，优势度指数减小；从类型水平上看，5年间人类对景观的干预程度较大，对人工景观的干扰强于半自然景观，体现在半自然景观类型的分离度较小，而人工景观类型的分离度较大。

Years (1873～1993) seasonal time series of SOI and NAOI areanalyzed by means of orthogonal wavelet transform.

用正交小波变换方法分析了近121年来季节的南方涛动指数与北大西洋涛动指数的演变特征，结果表明南方涛动指数最显著的变化是周期约为2～7年的年际变化，它们的方差贡献率为55.1%。1920年以前和1960年以后SO年际及年代际变化较强，其余时段较弱。

Using the historical MSLP data, the long series of NPOI, NAOI are calculated from 1873 for every month. A long AOI from 1871 for January, April, July and October also established.
