    It is shown that the total life of a parallel system with independent and identical (i.i.d.) exponential components is smaller in the right spread order than an exponential life with the same mean as the system.
          
    The main factor responsible for fracture is found to be the coalescence of dispersed cracks, especially at the final stage, which accounts for about 30% of the total life.
          
    This period accounts for about 89.5% of the total life of the specimen for steel 45 and about 81.6% for steel 12KhN3A.

    The development of a complex electronic system may be divided into several stages. Let λ1 be the failure rate of the system in the i-th stage. In many situations, the reliability of the system increases stage by stage, i. e. λ1>λ2>…> λm. we choose the prior distributions of λ's to be such that the Bayes confidence interval of A followed from the posterior density function is equivalent to the result of the classical statistics. Let f1 (τ1|λ1) be the conditional probability function, where τ1 is the total...

Let f1 (τ1|λ1) be the conditional probability function, where τ1 is the total life time in the i-th stage, then the posterior density function isthe marginal posterior density function of Am iswhere is, the space formed by is the domain of λj, and is the subspace of 0. The r-confidence interval of λm is(o, λm…), whereIn classical statistics, we can only use rm to calculate the r-confidence interval for Am, because the statistics r, (i = 1,2, …, m-1) belong to another population. But now we can use the formulas derived in this paper to calculate the r-confidence interval for Am not only by using rm, but also by using τ1, τ2, …, rm-1. The size of the sample of the m-th stage using this method will be smaller than the sample of the m-th stage using the classical statistics.

It is found that at 30℃ Moina affinis has a higher rate of egg production (a=1.1811) than at 20℃ (a=0.9643)The data on the life cycle of Moina affinis has been compared with other five cladoceran species.

    近亲裸腹溞(Moina affinis)的胚胎发育和总生活时间与温度呈反比。其后各龄期的生长、卵的生产量与温度的变化密切相关。30℃时,总胚胎发育时间为18—20小时,平均龄期为25.1小时,总生活时间为15.7天;20℃时,总胚胎发育时间为42—48小时,平均龄期为53.2小时,总生活时间为33.3天。在30℃时,有2个成体前龄,13个成龄;而在20℃时,有3个成体前龄,12个成龄。不论30℃或20℃,幼龄的龄期短于成龄龄期。近亲裸腹溞各个不同龄期的生长也因温度而变化。30℃时,10龄之前,以1、2龄的增长尤为迅速,而10龄以后增长速度则缓慢;在20℃时,第1—4龄,第6—7龄增长速度最快,第10龄后,增长趋于停止。30℃时,各成龄的累计产卵数为133.0个;而20℃为213.9个。30℃时卵的生产率(a值)为1.1811;高于20℃时的a值0.9643。

    This article gives several new results of the characters of stationary non-after-effect streams under rather weak assumptions on distribution functions. The results in theorem 1 and 2 are concerned with total life. In theorem 3 and 4, the stationary non-after-effect streams are defined by using relevant conditional distribution, which is quite heuristic, and moreover, the distributions concerned are very similar to uniform distribution and can thus be easily tested.

    This article gives several new results of the characters of stationary non-after-effect streams under rather weak assumptions on distribution functions. The results in theorem 1 and 2 are concerned with total life. In theorem 3 and 4, the stationary non-after-effect streams are defined by using relevant conditional distribution, which is quite heuristic, and moreover, the distributions concerned are very similar to uniform distribution and can thus be easily tested. All of the result can be used in Poisson stream parallelly.
