正义并非通过像我曾经听到的那样，&当证人已经表示没有看到车的转向灯的情况，还问证人为什么没看到&这样的方式来推动；也不是通过强迫一位在骑自行车时被摩托车撞飞的人来准确阐述自己车身的哪一部分受力的方式来推动。

In order to develop and modify Gregory scheme for cumulus convective parameterization,we make the improvement as follows:(1) The large-scale moisture convergence is taken into account and the organized inflow,which occurs in the area of large-scale moisture convergence and is directly proportional to it, is added to turbulent airflow.(2) The influence on saturation vapor pressure exerted by supercooled water is taken into account and the initial mass flux is adjusted. Based on diagnosis of the air heating and moistening, the downdraft airflow is adjusted.(3) Based on the character of our country heavy rainfall,which usually occurs in the mixed cloud consisted of stratocumulus and cumulus, the process of excessive convection is restrained by organized outflow in the top of cloud and improving downdraft current and by reducing the evaporation of rainfall and release of latent heat.

为了改进和发展Gregory积云参数化方案，(1)考虑了大尺度水汽辐合对积云对流的影响，即在混合卷入中加入有组织的卷入，让有组织的卷入存在于有大尺度水汽辐合的层次上，并且与大尺度水汽辐合直接成比例；(2)考虑了过冷水存在对饱和比湿的影响，调整了初始的质量通量，并且根据对大气加热加湿的诊断，调整了大气向下拖曳的强度；(3)根据我国降水多由层状云和嵌入其中的对流云混合产生的这一特点，对于过强对流过程进行抑制，在云顶加入有组织的卷出，同时加大向下拖曳的强度，减少蒸发以降低潜热的释放，抑制过强对流的发生。

In order to obtain the fire parameters of cable tunnels and study the time-dependent and spacedependent distribution of the air temperatures and fire smokes inside the tunnels, cable tunnel model is established and fullscale fire simulation is made by means of FDS developed by NIST (National Institute of Standards and Technology). The distribution pattern of the smoke density, oxygen density and temperature are obtained by means of processing and analysis of the experiment data, so as to provide some effective methods for fire-fighting, rescuing and escaping. Furthermore, some suggestion is made on fire prevention.
