绝对矩

Two improvements measurements pointed to the errors to calculating b values have been proposed:(1) to adopt the uniform absolute magnitude scale, seismic moment magnitude MW,(2) to discard the magnitude points for which the earthquakes absent and lose, and then to compute the b value using least square method to fit the data.

针对过去计算b值的误差，提出了两条改进措施：（1）采用统一的绝对震级标度-矩震级标度MW；（2）舍弃缺失地震次数的点，然后用最小二乘拟合求得b值，使b值计算较准确。

First, we discuss several theories of risk measures respectively such as theories ofcoherent measures of risk, spectral measures of risk and distortion measures of risk.Within the framework of these theories, we discuss and compare standard deviation,mean absolute deviation, lower partial moment, Ginis difference, VaR, CVaR and soon. We conclude that CVaR is superior to other measures with respect to theoreticalproperties.

首先，本文分别讨论了一致风险测度理论、谱风险测度理论、失真风险测度理论和随机占优一致风险测度理论等风险度量评价理论，在这些理论框架内讨论和比较了标准差、平均绝对离差、下偏位矩、基尼均差、VaR以及CVaR等风险度量。

Methods Estradiol-randomly methylated β-cyclodextrin (E2-RAMEB) solution, and 70% ethanol solution of estradiol and estradiol nasal spray in 3 different doses 0.16、0.48、1.60 mgkg^(-1 were nasally administrated to rats, respectively. Non-compartment statistical moment method was used in pharmacokinetics study.

对大鼠鼻腔给予雌二醇-随机甲基化β-环糊精包合物的生理盐水溶液、雌二醇乙醇溶液和3种剂量的雌二醇鼻腔喷雾剂，用非隔室模型统计矩法进行了药物动力学研究，并与静脉注射雌二醇相比较计算绝对生物利用度。

The influencing factors that glutathione molecular umbrella penetrates lipid bilayers with the shielded conformation were analyzed with VolSurf parameters. The results show that the major influencing factors are smaller amphiphilic moment and larger molecular rugosity of the shielded conformation, which are independent of definite hydrophobic regions of the conformation.

利用VolSurf参数分析了分子伞以屏蔽构象穿透磷脂双分子层的影响因素，结果表明屏蔽构象较小的两亲矩及较大的分子褶皱程度是其能够穿透细胞膜的主要影响因素，与构象的绝对疏水区域无关。
