将实考考生看作为考生总体的一个简单随机样本，应用抽样估值的方法，在若干合适的概率分布模型下，收集和推演了考生总体合格率的一些估计公式，以估计有考生缺考时，考生总体的合格率。

Using quasi birth and death chain and matrix-geometric solution method, we obtain the distribution of the number of customers in the system, the average number of the customers and the average sojourn time of a customer in the stationary state.

应用拟生灭链以及矩阵几何解的方法，本文给出了稳态下顾客数的概率分布、平均队长以及顾客的平均逗留时间，最后通过数值例子说明我们的模型可以较好的模拟一些实际问题。

The study shows that the subsalt carbonate rocks of Cambrian in Tarim basin possess favorable exploration prospect, the favorable areas or zones are located in the main host belts of Tazhong uplift and its two sides, Yingmaili and Lunnan areas in Tabei uplift and southern structural belt of Bachu swell, based on the source-reservoir-cap rock assemblage, structural development, sedimentary environment, oil-gas shows and the petroleum accumulation characteristics of the two basins.

根据寒武系的生储盖组合、构造发育、沉积环境以及油气显示情况，并对比东西伯利亚盆地油气田油气成藏的特点认为，塔里木盆地寒武系盐下具有良好的勘探前景，有利勘探区带主要为塔中主垒带及其两侧、塔北隆起的英买力及轮南地区、巴楚低凸起的南部构造带。

Two kinds of sulfonium salt s as photo-acid generator possess high thermo-decomposition temperature and good solubility in some organic solvents.

对合成的两种新型锍鎓盐光生酸剂进行了基本物性考察，表明它们有较高的热分解温度和在常用有机溶剂中有较好的溶解性，并考察了其在405、365nm 下乙腈中的分解及产酸性能。

From "Dao"comes to heart,to human nature,at last it runs through the life situation of man being an integal part of nature,"Dao"is the intensive bases of the superorganic ethies houmenon of Yizhuan.

易传》是阴阳理论衍生出的《易传》的宇宙创生模式，"道"是其核心内容，从"道"向下落实到人心、人性，最后贯通于"天人合一"的人生境界，"道"是《易传》形上道德本体的内涵依据。

In vivo whole-cell recording from the tectum of Xenopus tadpoles showed that repetitive dimming-light stimulation applied to the contralateral eye resulted in persistent enhancement of glutamatergic inputs, but not GABAergic or glycinergic inputs, on tectal neurons. This enhancement can be attributed to potentiation of retinotectal synapses.

在生体培养爪蟾蝌蚪四叠体中，以微暗的环境下激发对侧的的眼睛，可造成强烈激化麸胺酸型的突触传导，但却不激发胺基苯甲酸型与甘胺酸型的突触传导。

Thanks to $50 billion in federal loans for GM and $16 billion for Chrysler and the government-supervised "quick rinse" bankruptcies that magically made unsupportable liabilities disappear, both companies emerged from Chapter 11 after little more than 40 days, leaner, fitter and supposedly ready to fight another day.

多亏了给通用的500亿美元联邦贷款，以及给克莱斯勒的160亿美元贷款，再加上政府监管下的"快速清理"式破产使得那些无法清偿的债务魔法般地消失了，两家公司只用了40多天时间就从11号法案中重生了，更精干、更高效，而且据说已准备好再次投入战斗。

Several unvarying and effective methods of directional fracture controlled blasting are introduced in this paper.

本文介绍了定向断裂控制爆破的几种常用而有效的方法，通过计算爆破冲击波作用下炮孔壁的环向拉应力和爆生气体压力来分析了定向断裂控制爆破的机理。

Photoconductive materials are a new type of high technology information materials which can generate e-h pairs upon illumination. These materials have been extensively used in copier application, hologram and digital xerography. Among them, organic photoconductive materials have shown their special position.

光电导材料是指在光的辐射下能引起光生载流子的形成并迁移的一类新型高技术信息材料，广泛用于静电复印、全息照相和激光打印等领域，其中有机光电导材料已经显示其特别重要的地位。
