  1. The influence of the cloud droplet spectrum character and the spectrum growth and change is considered, which does not use a cut - off value for conversion from cloud water into rain water process. in the continuous coalescence equation, the particles fall velocity difference is not moved out from the integral, but is integrated in the equation as the function of diameter d to avoid the error of using particles average fall velocity. in the new scheme, generation rate of graupel due to the collection of snow by graupel and the collection of cloud ice by graupel are included

    雲中凝結核ccn的數濃度採用超幾何函數表示；雲水向雨水的自動轉換過程採用grabowski （ 1999 ）的公式，考慮了雲滴譜的特徵和發展變化對該過程的影響，而不是採用原方案給定閾值的方法描述該過程；對連續碰並方程不再將粒子落速差作為常量提出積分號外，而是直接作為粒子直徑函數在積分號內求解，這樣處理可以迴避使用粒子群的平均落速帶來的誤差；增加了霰和雪、霰和冰晶的碰並微物理過程。
  2. On the basis of the study of traffic features of heavy - load vehicles, the vehicle weight data and the axle - load spectrum of different vehicles were collected for some typical heavy - duty roads in china, and according to the features of heavy - loading pavement, deficiency of the former load - figure are analyzed and new figures which are suitable for heavy - load pavements are put forward. meanwhile, based on the research of the cement concrete fatigue equation and the damage mechanism of asphalt pavement under heavy - load vehicles, axle load conversion equations fitting for heavy - load cement concrete pavement and asphalt pavement are established respectively by further analysis. in addition, design indices, traffic and material parameters and structural combination for heavy - load pavements are discussed in this paper as well
