移影鄉函數 例句

1. It contributes to the deeper comprehesion of these probability distributions, affords more detailed theoretical basis for further studying and simulating satellite mobile channels, ? theoretical analyses and discussions of the models which are often used in the study of the propagating characteristics of satallite mobile channels are given ; meantime, some discussions on the work of model simulations are also given, ? incorrect derivation of the equality between c. loo model and corazza model in some other papers is pointed out. via the conception of received power, we derivate that in the rural environments these two models really have the equal relationship by the way of theoretical derivation and simulatant fittings. therefore, it is able to use corazza model in studying the characteristics of satellite mobile channels in the rural environments and able to avoid the iterant work of modeling, in order to enhance the efficiency and accuracy of research work, ? detailed processes of simulating lutz model by using matlab6. 0 _ simulink4. 0 and the results of comparisions are given
