查询词典 difficult problem

Interference is most difficult to be avoided while measuring the weak signal, Especially when the signal is only at microvolt level.X9313 is a kind of digitally controlled dissurbacne potentiometer produced by Xicor company.We succeed in using it to solve the problem that the signal is too strong, and get the useful signal in a weak signal measurement device.

微信号检测中最难避免的就是干扰问题，特别是在信号仅为微伏级时，信号相对于干扰来说，几乎被完全淹没，因此，研究如何在干扰信号很大的情况下尽可能地检测出有用信号有着极其重要的意义。X9313是Xicor公司推出的一种数字电位器，在某微弱信号检测装置中，采用X9313可成功解决干扰信号过大的问题。

It is very difficult to avoid miscarriage of criminal justice completely, but errors continued in the later part of procedure is a problem worth thinking.

Based on quantitative type AHP that combine with grey relational grade analysis, we built up a hierarchy-relational synthetic majorized model for multiple attribute decision problem that without information and it is difficult to determine the weight of indexes. We evade pessimistic principle、optimistic principle and eclectic principle these simple methods that we used before.

对于无信息而又难于确定指标权重的多指标决策问题，避开了以往所采用的悲观原则、乐观原则及折衷原则几种简单的方法，在定量型层次分析法的基础上，结合灰色关联度分析法，建立了层次—关联综合优化模型。
