The paper consists of three parts. First, we give the calculation for every order central moment for the Logistic population, mean vector and covariance matrix of the order statistic of random sample from the Logistic population, and means of several special functions for the order statistic of random sample from the Logistic population. Secondly, we discuss the parameter estimation for the Logistic population. Finally, we solve the question about the goodness-of -fit test for the Logistic population.

研究的主要内容分三部分：第一部分是关于Logistic总体各阶中心矩、样本次序统计量期望向量与协方差阵及若干个特殊的样本次序统计量函数期望的计算问题；第二部分是关于Logistic总体分布参数的估计问题；第三部分是关于Logistic总体的拟合优度检验问题。

The results indicate that the ST-EPR spectra of the former is significantly different from that of the latter. In cholate treated sample remarkably changes in the spectral diagnostic parameters L"/L, C'/C and H"/H are found and they are higher than in the control sample obviously.

本文比较了经胆酸处理和对照样品的马未酰亚胺自旋标记的F_1-F_0酶复合体的ST-EPR波谱，二者波谱呈现明显不同的形态。

Our factory's surcharge is very low,we have no rent,and the workers are close-by inhabitant,it must reduce the price of products,lower price at same quality,we are not only emphasize on price but also reputation,we can produce the same quality mass product with samples,it is the key for our living and development,we have our own designer,we can make sample according to buyer's requirements until to buys are satisfied with the sample,and we are welcome design/make samples and processing on order,we can assure our offer is much lower than other.

我厂自身附加费用低，无厂房租金，，工人均为附近居民，这样必然降低产品的整体成本，同等质量的产品价格低，我厂不仅注重价格，更注重信誉，所做大货与样品一致，绝不偷工减料，这是我们生存和发展的法宝，我厂拥有专业的设计人才，可协助客户设计制作产品，满意为止，而且可单独承接设计，打样，来料加工，价格均为行内最低价。

After the sample is dissolved and the disturbance eliminated, then dithizone and chloroform solution are added in the sample. According to the direct ratio relationship in a certain range between the color degree of the organic solvent with Pb2+ and dithizone in the complex compound and the amount of the lead, the amount of the lead can be rapidly determined by way of the visual colorimetric.

样品消解并消除干扰离子后，加入双硫腙的三氯甲烷溶液，根据铅与双硫腙生成的络合物在有机溶剂中的颜色深浅与铅含量在一定范围内成正比的关系，用目视比色法即可快速判断出样品中的铅含量。

However, via intensive numerical computation, the author finds that actually some characteristic of this confidence intervals, for example, confidence coefficient, expectation width and coverage efficiency fluctuate intensely when the sample size varies given the parameter, or when the parameter varies given the sample size.

但是我们通过精细的数值计算发现，由于总体分布的离散性，这些置信区间的特性(置信系数、期望长度、覆盖效率)实际表现为当参数固定随着观测次数变化或当观测次数固定随着参数变化而发生强烈震动。
