Given the failure rates for given subsystems , the six sigma black belt will be able to use reliability apportionment to set mtbf goals 给出给定子系统的故障率， 6西格玛黑带应能利用可靠性分配原则设定平均无故障时间目标。
He notes that high availability is an important concept in mission - critical systems that depend on 24 7 uptimes and high - transaction loads 他指出，在依赖于24 / 7无故障运行时间和高事务负载的关键任务系统中，高可用性非常重要。
Since some element ' s mtbfs cannot meet design requirements , redundant technology is applied to improve the system reliability 由于原系统某些部件平均无故障工作时间达不到要求，本文采用冗馀技术加以改进，提高了整个系统的可靠性。
Spice experiments were done to simulate the dynamic currents of both the fault circuits and fault free circuits under the function of testing pairs 对于这些测试向量对，通过spice软件模拟了故障电路和无故障电路在测试向量对作用下的动态电流。
Work 100 , 000 hours without maintenance ; imported longevous 200w electrical machine , passed the 3c certification . save electricity and be mute 引进超长寿命的200w电机， 10万小时工作无故障，并通过3c品质认证，保证低耗能静音运行，更符合绿色环保标准。
The fault can be diagnosed by variance analysis or distance classification after getting the correlation functions between the input and output of cut 得到cut输入和输出之间的互相关函数后,可以采用方差特征分析法或者距离分类算法来判断电路有无故障。
However , since it is implemented entirely in java , understanding the java class path is the key to a trouble free - and not a troublesome ! - installation 但是因为cloudscape完全是用java实现的，所以了解java类路径是进行无故障（以及轻松）安装的关键。
Disc stem nut : disc stem ring connects the disc to the stem , permitting the disc to swivel and aid in securing tight seating for trouble - free service 阀瓣阀杆螺母：阀瓣阀杆环将阀瓣连接到阀杆上，使得阀瓣能够旋转，并有助于保证阀座地紧密密封和无故障运行。
An indicator , usually in the form of a led or a lcd , to show the operation status , e . g . power on power off ; successful unsuccessful operation , of the reader 显示器通常分led及lcd两类，功用在于显示阅读器的运作状况，例如电源是否接通、运作有无故障等。
Secure system : assure that the system of problem 9 services only authorized users , service cannot be denied by unauthorized users , and information cannot be stolen ( and prove it 无故障系统：建造一个系统，每天可供上百万人使用，而只需要一个非全时工作人员管理。
