However, there is little discussion on reliability evaluation of nonworking redundant systems such as cold and warm stand-by systems in literature, especially there is no discussion in case of medium and small sample size.

本文结合总装备部九五预研重点课题《小子样系统可靠性综合方法研究》和我国工程实际，较系统地研究了常见各种贮备系统的可靠性评估问题，包括冷备和温备两种贮备类型，指数型和Weibull型两类部件，完全可靠、成败型和指数型三种开关，以及定数、定时、和定总时截尾三种指数型试验数据。对上述各种常见情况下的贮备系统，分别给出系统可靠度函数及其点估计，并用WCF方法导出了可靠度置信下限。

P. denasta harbored the three chlorotypes, two of which were characteristic of its two parental species respectively. The third chlorotype was extensively distributed in seven of the ten P. densata populations analyzed, and might represent a mutation type or have been derived from an extinct parent. Population differentiation of P.

TT和GC分别是油松和云南松种特异性叶绿体单倍型，而在高山松群体里则三种单倍型均有分布，而且TC单倍型广泛地分布在7个杂种群体中，该单倍型很可能来源于点突变或第三个已灭绝的亲本。rbcL基因检测到的高山松群体分化系数很高（G〓=0.533）。

The Yankees twice wasted opportunities with the tying run 90 feet away. Derek Jeter legged out a one-out triple in the sixth, but was left on third base, as Jackson got Bobby Abreu to ground out and induced Matsui to pop weakly to shortstop. In the seventh, Shelley Duncan pinch-hit and struck out looking to pin Cabrera in scoring position.

洋基浪费了两次追平分只在90呎远的机会，6局时基特一出局时跑出一支三垒安打结果却留下残垒，因为Edwin Jackson让阿伯滚地球出局而松井只击出游击方向的软弱小飞球，而第7局代打的雪莉站著被三振让牛奶只能钉在得点圈上。

Icosehedral quasicrystal, showing icosahedral point group symmetry and quasi-periodic order along three directions, has been intensively studied.

二十面体准晶是目前研究最广泛的准晶之，它具有二十面体点群对称性，属于三维准晶，就是说其原子在三维上都是准周期分布的。

On the one hand, we improve the mixed having and ternary method to express n from the standard non-singular elliptic curve with character 2. On the other hand, we improve the mixed binary and ternary method to express n from the standard elliptic curve with character more than 3 , and we generalize the mixed binary, ternary and quinary method to express n.

一方面从特征是2的有限域上的标准非奇异椭圆曲线的角度出发，改进了n的半点和三进制的形式；另一方面从特征大于3的有限域上的标准椭圆曲线的角度出发，改进了n的二进制和三进制的混合形式，并推广到n的二进制、三进制和五进制的混合形式。

Spherical triangle : the sphere of the three point arc banded together with three large, surrounded by the graph is called spherical triangle .

球面三角形：把球面上的三个点用三个大圆弧联结起来，所围成的图形叫做球面三角形。

Three experiments in this article examined the TRP theory's assumption that minimum requirement is steadier than goal.

本论文的三项实验研究对三参照点理论底线比目标更稳定的假设进行了验证。

No significant results are found on the interaction of language and format to reading comprehension and eye movement indexes.2. For one-, two- and three-column texts, no significant differences are found on reading comprehension indexes but among such indexes as saccade length, number of within-line and multiple-line regression. Compared with two- and three-column text, one-column text is the best. Moreover, the number of fixation, fixation frequency, fixation duration and total regression numbers of one-column text are also better.

语种和开本在阅读理解指标与眼动指标上的交互效应均不显著。2一栏、二栏、三栏设计材料在阅读理解指标上没有显著差异，但在眼跳距离、行内与行间回视次数上有显著差异，表现为一栏最优，且一栏设计材料的注视次数、注视频率、注视点持续时间和总回视次数等眼动指标都优于二栏、三栏材料。

The graph in isometric drawing must be consistent with the topology relations in the threedimensional model, but not be drawn in one uniform scale. Based on the result of analyzing the rules in isometric drawing, the templatebased method is proposed for representing the different and unrelated drawing rules in an uniformed way.

ISO图模型的建立：针对ISO图的自动生成时所需的工厂管道的三维模型和二维图纸模型的统一性要求，提出了一种基于点线关系模型的二三维一体化模型解决方案，把三维空间中工厂管道模型和二维图纸空间中的管道图形统一起来，为二三维模型中的各种功能提供了基础。

To perform CRS stack depends on the determination of three wave attributes,compared with conventional common middle point stack and dip move out stack,CRS stack can focus more energy in the vicinity of the reflector,therefore can obtain a better zero offset section by stacking events with same phase.

共反射面元的旅行时响应由三个波场属性参数确定，相比常规共中心点(commonmiddlepoin ，CMP)叠加和倾角时差校正(dipmoveout，DMO)叠加，CRS叠加算子能够将地下反射点附近一个邻域内的能量进行聚焦并实现同相叠加，因此能得到更好的零炮检距剖面。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
