So it has made the great progress. The method studied in this research from o-Dichlorobenzene is a ideal route to synthesize 2,4- dichlorofluorobenzene, which has temperate condition easy to control,safe process,low cost and good quality of products; The method of Phase transfer catalysis fluorination without solvent is better than present technology in presence of DMSO as solvent in many aspects; In a word,it is worth being promoted by the domestic correlative factories.

本课题所研究的以邻二氯苯为原料的2，4-二氯氟苯合成路线反应条件温和，工艺容易控制，生产安全，而且产品质量好，是比较理想的合成路线；以季胺盐为催化剂的无溶剂相转移催化氟化法与溶剂法相比具有明显的优势；通过实验确定的工艺条件对工业化生产有重要的指导意义，可提高以邻二氯苯为原料的工艺路线的市场竞争力。

In order to solve the problems in practice, we usually ignore and abandon the factors that are subsidiary and dispensable to our research. Instead, we need to get hold of the main essential factors. This idea is called "ignoring process".

为更好的解决实际问题，我们常常忽略、舍弃、次要的，非本质的，对我们所研究的问题不重要的因素，而抓住主要的、本质的因素，这种即"忽略不计"思想。

This article first has carded on the limits to the spirit security concept,then discusses in this foundation by the Mallow's Hierarchy of Needs theory,social safety-valve theory, harmonious society theory as theoretical stupors of spirit protection,Pointed out that the spiritual security supply and demand contradictory prominent,the spiritual security emergency lag is the existence subject matter in our country spirit security development.The reasons are manifold.If we want to achieve the spirit protection,we must steps in the multiple participation,the system design recuperation,the theoretical research strengthen and the integration of multiple resources. Only in this way,Social security can play the role of social safety net and truly promote social harmony.

本文首先对精神保障的概念进行了界定，并在此基础上以马斯洛需求层次论、社会安全阀理论、和谐社会理论等作为支撑，对我国精神保障的发展现状进行了分析，指出精神保障供求矛盾突出、精神保障应急滞后是目前我国精神保障发展存在的主要问题，而其原因是多方面的，所以一定要通过多元主体的参与、制度设计的调理、理论研究的强化、多方资源的整合等才能达成精神保障的发展，才能更好的发挥社会保障的安全网作用，真正促进社会和谐。

Frequently, this buyer's major contribution will be to change accounting methods so that earnings can be presented in the most favorable light just prior to his bailing out.

I'm enclosing a list of everyone from whom we have ever bought a business， and I invite you to check 44 (2)第二类的公司是财务公司，大量运用所借来的资金，只要时机得当，总是准备随时将公司再卖给投资大众或是别的大企业，通常这类买主对公司最大的贡献就是改变公司的会计政策，使得公司盈余比以前看起来好看一点，如此一来使他得以用更好的价格脱手而出，附件是最近一篇有关这类交易的文章报导，由于最近股市热络所以这类的活动也相当频繁，同时这类的资金也相当充沛。

Because of its easily calculating and its accurately description parametric method has became mainstream in study field, polynomial hazard function distribution model was a large class of parametric models, when the dates are not readily handled by one of the common models such as exponential distribution or Weibull distribution, polynomial hazard function model always be used to provide adequate fits of the dates.

随着该学科的发展，大量参数、非参数方法相继提出，特别是生存分析的参数方法，以其处理简便、描述准确成为生存分析研究的主流方向。多项式危险函数模型是参数模型中的一大类，当一批数据不能用熟知的一些分布，诸如Weibull分布、对数正态分布进行很好的描述时，常常使用多项式危险函数模型。

The advantages and limitations of every kind of methods for calculating the failure probability is reviewed. The frist order reliability method, the second order reliability method and many kinds of boundary method have achieved remarkable success and formed nature fields of reliability. However, the precision of these methods decrease as the increase of complexity of problem. The numrical methods are versatile, except numerical intergration is only adaptable to special problems which have small number variables and regular intergral domain. Particularly, the advanced variance reduction techniques own the following character: high precision and a small amount computation. But some questions remain to study in the future because only an initial work about these techniqes is developed.

全面评述了计算失效概率各种方法的优点和局限性，其中经典的解析法包括一次可靠性方法、二次可靠性方法、一阶边界法、Vanmarcke上边界、PENT上边界和Ditlevsen二阶窄边界法，这些方法对于多设计点、变量较多且相关、密度函数不是正态以及极限状态方程较复杂的情况，其计算精度较差；而已有的数值方法却是具有较好的通用性，其中除数值积分法只对变量较少、积分域较规则的特殊问题适用外，各种数值模拟方法均具有较广的适应性，特别是各种改进的方差减小技术，精度高、计算量小，但由于其处在研究的初级阶段，还有许多问题有待于解决。
