For the first time, on the basis of the principle design scheme of the system, the reliability analysis of the new type of electromechanical fluid drive system and its subsystem is carried out overall and systematically, which contents include reliability model building, reliability prediction and distribution, failure mode and effect analysis , fault tree analysis of the straight-rotary ball actuator.

基于本文提出的系统原理设计方案，首次对飞行器新型机电液驱动系统及滚珠直旋作动器子系统进行了较全面、系统的可靠性分析，包括系统与子系统可靠性建模，系统的可靠性预测与分配，系统的失效模式及影响分析，系统的故障树分析等，并结合给定设计指标对现有系统和子系统的可靠性进行了分析与评价，指出了提高系统及部件可靠度的措施。

Effects : Finds an iterator to the first element whose key is "key" according to the given hasher and equality functor or end if that element does not exist.

作用： 找到一个迭代器，指向按给定散列函数及相等性函数其键值为"key"的第一个元素，如果该元素不存在，返回 end。

The hash function is the very core of the fast lookup capabilities of the unordered sets: a hasher is just a Unary Function returning an std::size_t value for any given key.

散 列函数是无序集合的快速查找能力的核心：散列器就是一个可以对任意给定的键值返回一个 std：：size_t 值的单参函数对象。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
