Therefore, it has the important scientific research value in studying the relationship between the changing of the parameters (including the temperature, the humidity, the grain radius and so on) and the electricity and radioactivity of the medium. Applied the count statistics and the numeral value analysis, the paper analyzes, concludes and contrasts the data sufficiently through the experimentation, and acquires the following results that the resistivity and the polarizability both have the negative relationship with the temperature variety of medium from 0℃ to 200 ℃. The parallactic poalarizability is consistent with the temperature variety in the plan as well as the section, but their trends are exactly opposite. Power supply voltage has no considerable influence to the resistivity and polarizability by using duality variance analysis, however, the detecting depth and the plan position influence them greatly. Different AB/2 interval that increases by degree does not influence variance and the average value of the resistivity and the polarizability remarkably. By using the least double multiplication, the relationship of temperature-time-the influence radius of the fire source is carried up by the mathematic drawing up. After discussing their correl ation, I educe the influence radius of the fire source and carry out the 'trend analysis and forecast to the spacial changing of the temperature and the parallactic polarizability in the end.

本文通过试验并应用数理统计和数值分析等相关理论对所得到的试验数据进行了分析、归纳和对比，得出了介质温度变化在0-200℃内视电阻率和视极化率与温度均表现为负相关性；视极化率与温度在剖面和平面上的变化形态具有很好的一致性，但变化趋势相反；由二元方差分析可得供电电压对视电阻率和视极化率无显著影响，但探测深度和平面位置对视电阻率和视极化率有显著影响；通过假设检验可证不同AB／2递增间隔，对视电阻率和视极化率的方差和平均数影响都无显著性差异；应用最小二乘法对温度——时间——火源影响半径之间的关系进行了数学拟合，讨论了它们之间的相互关系，得出了火源影响的有效半径，太原理工大学硕士研究生学位论文并对温度和视极化率的空间变化作了趋势分析和预测。

The time to peak systolic longitudinal strain and the time to peak systolic radial strain were derived from the LV apical views , and to peak systolic circumferential strain was derived from the parasternal short axis. The standard deviation for time to peak longitudinal、circumferential and radial strain in the 18 segments (LS-SD18、CS-SD18、RS-SD18) and the maximal temporal difference of any two segments(LS-dif、CS-dif、RS-dif)were calculated as a strain-derived dyssynchrony index.

objective to search the factors of liver injury via the anit-induced liver injury in rats.methods male sprague-dawley rats,were divided into 4 groups,data were analyzed using a completely randmized factorial anova and linear correlation.results after anit intoxication,the necrosis of hepatic cell and neutrophil infiltration im periportal region of the liver were observed in liver setions.jinshisan can reduce the alt,the tbil.pla2 correlated positively with alt、akp and tbil.conclusion the severity of anit-induced liver injury correlated positively with the pla2.jinshisan can protect against the rat anit-induced liver injury.

目的 拟通过对α－萘异硫氰酸酯诱导大鼠肝损伤发病机理的探讨，对引起肝损伤的因素进行系统的研究。方法选择s-d大鼠，雄性，随机分4组，检测数据以平均值±标准差表示，采用方差分析，相关分析进行统计学处理。结果s-d大鼠经anit染毒后，病理切片显示肝损伤明显，汇管区有大量中性粒细胞浸润。经金石散及地塞米松治疗后，生化指标均有所下降，中药金石散优于地塞米松，血生化指标与pla2活性相关分析显示，呈正相关。结论 anit诱导的肝毒性损伤程度与肝组织匀浆pla2活力呈正相关，应用抑制剂降低pla2活力，肝损伤程度也减轻，中药金石散具有降低pla2活性，减轻肝毒性损伤。

These three internal fixations of femoral peritrochanteric fracture were differ. For example, Gamma nail is less harmful, better clinical treatment, shorter in shape and stronger in anti-hip inversion. DHS, DCS have a better treatment and are stronger in anti-hip inversion but more harmful and excessive bleeding, and HCS, which is named Minimally Invasive Surgery, is the least harmful, less bleeding, suitable for old patients and the patients of tolerance of poor operation, but poor in anti-hip inversion.

3种不同方法内固定治疗转子间骨折具有各自的特点，Gamma钉具有手术损伤小及良好的临床疗效力臂短对抗髋内翻的能力强；滑动加压鹅头钉具有良好的临床疗效及相对坚强的抗内翻能力，但手术损伤相对较大，失血量较大；空心加压螺钉固定的手术损伤最小，属于微创手术方法，可经皮完成，手术出血少，适用于高龄及手术耐受性差的患者，但抗髋内翻的能力最差。

And the ability of antioxidant of polyhydroxy benzamides don't have too many differences with Trolox (IC50 =13.90 μg/ml), the substition of hydroxy group at amino benzene ring doesn't affect the whole ability of antioxidant apparently, but while the single hydroxy group at carboxylic acid benzene ring, they are apparently decrease to scavenge the ability of free radical, as a result, the hydroxy at amino benzene ring substitutes its function, without the hydroxy group, the ability of antioxidant is worst, but it upgrades its function while the hydroxy and amino are in the ortho-position or para-position.

而当多酚醯胺化合物其抗氧化能力与Trolox差不多时(IC50 =13.90 μg/ml)，胺基苯环上之羟基取代对整体抗氧化能力影响不明显，但在羧酸苯环上具单羟基时，其清除自由基能力明显下降，使得胺基苯环上羟基取代发挥了影响力，无羟基取代时，抗氧化能力最差，而羟基与胺基互为邻位或是对位时较间位有提升效果。

In this paper we assume the expected returns of the risky and risk-free assets as well as the covariance matrix of the risky assets are not exactly known, but defined by some known elements, which form the vertices of this polytope. Robust optimal portfolio problems are proposed in the market with and without risk-free asset. And the analytical solutions are given out when the covariance matrix of the risky assets are exactly known.
