Collateral type, substitution, ratio, and maintenance ratio. 担保品之种类、更换、比率及维持率计算。
Since the system parameters faulty coverage ratio and maintenance ratio influence the system's reliability and security, we analyze them and find out they play an important role in the evaluation of fault-tolerant system. 通过分析得出系统的故障覆盖率与维修率(MR)在容错系统的评价过程中起到非常重要的作用。
According to their mathematics ' model and taking the influences of the coverage ratio and maintenance ratio into account, we compiled the simulating programs with MATLAB language. 根据上述三种系统的数学模型,在考虑系统故障覆盖率与维修率(MR)两个参数对系统可靠度与安全度影响的情况下,用MATLAB语言编制了计算机仿真程序。
Maintenance the normal sex ratio at birth is the foundation to realize the population ecological equilibrium and the social sustainable development. 保持出生人口性别比正常,实现人口生态平衡,是社会可持续发展的基础。
With the scale and complexity of software engineering being on the rise, people feel that it is becoming harder to understand legacy software system than before which brings about the high cost in software maintenance and the low ratio of software reuse. 随着软件规模的不断扩大和软件工程复杂程度的不断提升,人们对遗产系统的理解变得越来越困难,导致软件维护成本高、复用率低的困境。
