平均寿命

Using the extended relativistic multi-configuration Dirac-Fock theory and the general-purpose relativistic atomic structure program 2(GRASP2) with quantum electrodynamical effect and breit correction, we have calculated the energy level structures, transition wavelengths, transition probabilities, oscillator strengths, energy level lifetimes, level widths and ionic average lifetimes of As-like Au~(46+), Ge-like Au~(47+) and Fe-like Au~(53+).

根据扩展的全相对论多组态Dirac-Foek理论，采用"多功能相对论原子结构程序GRASP~2(General-Purpose Relativistic Atomic Structure Program 2，1992)"，考虑量子电动力学效应和Breit修正，计算了激光金等离子体中类砷金Au~(46+)，类锗金Au~(47+)和类铁金Au~(53+)的能级结构、跃迁波长、跃迁几率、振子强度、能级寿命、能级宽度和离子平均寿命。

In the 20th century, life expectancy in wealthy nations increased by as much as 30 years.

在20世纪，发达国家的平均寿命增长了近30岁，美国平均寿命是78岁。

The early failure is judged and the validation test is assumed to obey the exponential distribution.

介绍了在正常应力下对家用微波炉的寿命试验及运用 F-检验判定异常小寿命数据的方法，以判定早期失效，对试验数据作指数分布假设下的有效性检验，估计样品的平均寿命，提出可靠性改进措

This paper has also done the following work to mend the bugs in the former version: Breaking through the size limit of screen, therefore, it took only one time to form the reliability block diagram of a complex system consisting of many components.;Three kinds of life distributions have been applied: Gamma,Beta,Weibull; Interborough estimate has been done to system MTTF; Optimizing the calculation method of complex system consisting of several sub-systems; Improving calculation speed greatly.

本文对上一版软件的不足部分加以了改进：突破了屏幕大小的限制，对于一个由很多元件组成的复杂大系统，只需一次就可以构造出其可靠性框图；增加了三种元件的寿命分布型式：伽玛分布、贝塔分布和威布尔分布等；增加了对系统的平均寿命的区间估计；改进了计算由几个子系统组成的复杂大系统的计算方法；全面提高了运算速度。

In this paper, the definitions of reliability and MTTF of unrepairable systems with fuzzy random lifetimes are given, respectively.

为了和传统可靠性理论保持一致，我们仍用系统可靠度和平均寿命作为衡量系统可靠性的主要指标，但是在这里我们给出了全新的定义，即系统可靠度定义为不可修系统在t时刻仍正常工作的平均机会，平均寿命定义为模糊随机不可修系统寿命的期望值。

In a probabilistic analysis of unrepairable systems, system behavior is described by reliability and mean time to failure, in which the reliability is defined by the probability of the random event "system is functioning at time t", and MTTF the expected value of random lifetime of system.

衡量不可修系统可靠性的指标主要是系统可靠度和平均寿命。其中系统可靠度定义为不可修系统在t时刻仍正常工作的概率，平均寿命定义为不可修系统寿命的期望值。

French life expectancy is also on the rise, at 77.1 years for men and 84 years for women, Insee said.

报道说，法国人的平均寿命也有所增加，目前男性的平均寿命为77.1岁，女性为84岁。

At 20.1℃ and RH 48.9%, The longest longevity and mean longevity per fe male and male of south-American leaf miner tested indoor in 1998, the following were 17d, 7d and 5.3d, 3d in 15%cane sugar cott on, and 19d, 6d; 10.6d, 3.5d in broad bean seedling.

在恒温20.1℃，RH48.9%的条件下，用蚕豆苗和用吸足15%的蔗糖水的棉球饲养南美斑潜蝇，测得雌、雄成虫的最长寿命、平均寿命及在蚕豆苗上的最高产卵量、平均产卵量。15%蔗糖水棉球饲养雌、雄成虫最长寿命及平均寿命是17d，7d，5.3d，3d。

WHEN Otto von Bismarck introduced the first pension for workers over 70 in 1889, the life expectancy of a Prussian was 45. In 1908, when Lloyd George bullied through a payment of five shillings a week for poor men who had reached 70, Britons, especially poor ones, were lucky to survive much past 50. By 1935, when America set up its Social Security system, the official pension age was 65—three years beyond the lifespan of the typical American.

1889年，当Otto von Bismarck 第一次推荐发放退休金给70岁以上的工人时，普鲁士人的平均寿命仅为45岁。1908年，Lloyd George 决定给70岁以上的穷人每周5先令，但在当时，英国人，特别是穷人，幸运的话可以活过50岁。1935年，美国人建立了一个社会保障体系，官方的发放年龄是65岁，这比当时美国人的平均寿命多出3年。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
