1) offshore coverage
近海覆盖
1.
Subsequently,the influence of rainfall,fog and cloud weather on radio propagation is analyzed,hence the rainfall and cloud loss calculation formula is proposed in offshore coverage environments.
首先得出近海覆盖电波传播最大视距距离,根据海面电波传播的二波传播特性推导计算电波在海面传播的无线传播损耗,随后分析了雨、雾、云对近海覆盖电波传播的影响,给出了雨、云衰减计算公式。
2) appromixately-coverring
近似覆盖
3) covering upper approximation
覆盖上近似
4) covering lower approximation
覆盖下近似
5) Near RSC-covering
近似RSC覆盖
6) covering approximation space
覆盖近似空间
1.
Reduction theory of covering approximation space;
覆盖近似空间的约简理论
2.
Secondly,since loss of information occurs in union and intersection operations of a covering rough inequality,so the sufficient condition that makes a covering rough inequality an equality is investigated in the covering approximation space.
其次,覆盖近似空间中,由于覆盖粗糙不等式在进行并、交运算时会使信息丢失,因而讨论了覆盖粗糙不等式取等号的充分条件。
