It also makes analysis on the connection of Newton's prism experiments, and describes how Newton proved these propositions by taking advantage of these experiments in the article. As well the author makes analysis and generalization on the make of Newton's reflecting telescope and Newton's

首先，在对《光学》认真研读的基础上，首次对其光的颜色理论部分的大量棱镜实验之间的关系进行了分析，从而说明牛顿是如何利用这些实验证明这些命题的；其次，笔者在前人研究的基础上，对反射望远镜的制造和牛顿环理论进行分析和总结，力求描述得清楚全面；最后，鉴于国内外对牛顿光本性认识的研究存在分歧的情况，笔者对惠更斯和牛顿的相关著作进行了详细考察，对他们的光本性观点进行了系统的研究和比较，从而指出那种只因牛顿

Less than one quarter of these high-risk deliveries occurred in high-level, high-volume facilities, yet 92% of very-low-birth-weight deliveries occurred in urban areas with more than 100 such deliveries, the researcher reported. This suggests that it would be geographically feasible to regionalize the vast majority of these deliveries in California.

不到四分之一的这些高风险婴儿是出生在高水平，大量病人的医院中，然而有92%极低出生体重婴儿出生在超过100个的市区，研究者报告，这说明在加利福尼亚州在地理学上更易于按地区找到绝大多数这些极低出生重婴儿。

Less than one quarter of these high-risk delieries occurred in high-leel, high-olume facilities, yet 92% of ery-low-birth-weight delieries occurred in urban areas with more than 100 such delieries, the researcher reported. This suggests that it would be geographically feasible to regionalize the ast majority of these delieries in California.

不到四分之一的这些高风险婴儿是出生在高水平，大量病人的医院中，然而有92%极低出生体重婴儿出生在超过100个的市区，研究者报告，这说明在加利福尼亚州在地理学上更易于按地区找到绝大多数这些极低出生重婴儿。

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。

In fact, the need to define these rights, which are essentially a reiteration of the optimal conditions for human existence, has arisen because these conditions are not met in the lives of the majority.

事实上，有必要界定这些权利，这基本上是一个重复的最佳条件，人类的生存，出现了，因为不符合这些条件的生活中占大多数。

Wastes are inevitable, but can be an effective way to reduce waste by the quantity and the resulting pollution, innovativeink liquid、cleanser, a MOP, these different kinds of waste contains a lot of organic solvents, not only pollute the environment, but also cause danger to human health, and so these three challenging rejectamenta bridleon treattheir.

废料的产生是不可避免的，但可以通过有效途径减少废料的数量以及所产生的污染，油墨、清洗剂、抹布这几种废料含有大量的有机溶剂，不仅污染环境，还会危害人体健康，因此对这3 种难处理的废弃物要谨慎对待。

Then we may ask: By situating these thinkers in these terms, do we thereby relativize their insights and claims?

我们或许会问：把思想家置于情境中，是否会把他们的洞见和主张相对化了？

The results show that the microstructures of these three kinds of coating are different from those of the matrix (20 steel). The wear resistance of the flame spray coating is 4. 9 times that of the matrix. This is caused by the existance of hard noncrystal microparticals. The wear resistance of the coating by flame spray welding is 6. 3 times that of the matrix. The reason is that the fine crystal grains can be formed and the solution strengthening, dispersion hardening can be induced by these alloy elements. The resistance of the laser remelt coating is 8. 8 times that of the matrix. This is due to the solution strengthening, dispersion hardening and the existence of very hard dendritic crystal, eutectic and martensite in the microstructure.

作者指出，喷涂层由于层内有一定数量高硬度的合金非晶质点存在，其耐磨性是钢基体的4.9倍；喷熔层内合金晶化产生的晶粒细小，合金元素能起固溶强化作用，也能生成化合物产生弥散硬化作用，故此耐磨性是钢基体的6.3倍；激光涂敷层除所含合金元素产生的固溶强化和弥散硬化作用外，表层组织为高硬度的枝晶+共晶和马氏体，故其耐磨性是钢基体的8.8倍。

Of course, the product that I say is not a specific thing, however a kind of service, it is namely it is a valuable article is Internet product, our broad stationmaster is the offer person of these products, we offer these products, it is free for the most part, of course the website that the netizen that our mainest purpose allows the throughout the country namely will come to to visit his, repass is other formal him gain work reward, this have bit of likeness with the TV station.

当然，我所说的"产品"并不是具体的一件东西，而是一种服务，即是是一篇有价值的文章都算是互联网"产品"，我们广大的站长就是这些产品的提供者，我们提供这些产品，大部分都是免费的，当然我们最主要的目的就是让全国的网友来访问自己的网站，再通过别的形式赚到自己的劳动报酬，这一点跟电视台有点相似。
