Based on rain drop size distribution ( dsd ) data measured in qingdao, guangzhou and xinxiang, the radar reflectivity factor z for spherical rain drops, the radar reflectivity factor zh and differential reflectivity zdr for oblate ellipsoid rain drops have been calculated. the relation of reflectivity and rainfall rate for conventional meteorological radar and the relation of reflectivity, differential reflectivity and rainfall rate for multiparameter radar are regressed, the performance difference of two kinds of radar for measuring rainfall and difference for measuring rainfall in different regions are also discussed
基於我國青島、廣州和新鄉地區雨滴尺寸分佈數據，計算了球形雨滴雷達反射因子，橢球形雨滴雷達水平極化反射因子和差分反射率，回歸給出了這些地區的常規氣象雷達反射因子與降雨率的經驗關系和多參數雷達水下極化雷達反射因子、差分反射率和降雨率關系，並對其測雨精度和地區差異進行了比較。 -

Then we calculate three correlation lengths in order to see what happens in low density. the second moment density - density correlation length n, 1 is from the density - density structure factor, the second moment charge - charge correlation length z, 1 is from the charge - charge structure factor, and the lebowitz length l is related to the charge fluctuation
我們計算了與密度一密度結構因子相聯系的密度一密度二級矩關聯長度g川，與電荷一電荷結構因子相聯系的電荷一電荷二級矩關聯長度久； ，以及與電荷漲落相聯系的lebowttz長度乙。 -
Second, using some subjects such as production management, system management, operational research, industrial engineering, etc ; the thsis builds a flexible work mode of enterprise on the basis of z. d. l electronic technology co. ltd., it analyses the main factor which construct the workcell work mode, then, studies varied convertible assembly line under the workcell work mode
其次，綜合運用生產管理、系統管理、運籌學和工業工程理論，在z . d . l電子有限公司的製造基礎上建立了柔性作業方式，並分析了workcell作業方式構成的要素。之後，研究了在workcell作業方式下多品種混流生產線的作業。 -
During the data processing, we mainly used explorative factor analysis, multiple linear regression, and z statistical test to verify hypotheses in the model
在數據處理過程中，我們主要利用因子分析、多元回歸和z統計檢驗等方法對模型進行了實證檢驗。
