Mainly aims at the rock structure in problem of coupling on the temperature and the stress, this paper investigates mechanism of rock structure weathering front expanding when rock suffers temperature of non-saturated zone environment.

本文主要针对岩石结构体温度与应力耦合问题,旨在研究在非饱和带环境中温度对岩石结构体风化前锋扩展过程的影响机理。

Analysis upon monzonite and basalt weathering process demonstrate that low permeability rock weathering front is promoted by moisture diffusion of which mode is composite between Fick and Knudsen diffusion.

以二长岩及玄武岩结构体风化过程为研究对象所进行的分析表明，水气分子的扩散是低渗透岩石风化前锋扩展的启动因素。

The new generation weather radar(CINRAD) data,intensively observed data from automatic meteorological stations and the products of meso-scale numerical model MM5 were used to analyze a gust front event in Yinchuan in arid Northwest China on 7 June 2004 based on the radar meteorological and meso-meteorological theories.

结果表明:这次突发短时大风天气由雷暴强烈下沉气流形成阵风锋引发。

Wind shear incidences are always related to local downburst, gust front or other systems.

对2005年7月21日发生在广州白云机场的一次低空风切变飞行事件进行分析,发现此次过程是由超级单体风暴云产生的下击暴流和阵风锋造成的。

Gust front is often produced by mesoscale convective system and produce low altitude wind shear that can be hazardous to aircraft operations.

阵风锋过程一般伴随中尺度强对流系统发生,在近地层形成很大的阵风及风切变,容易造成风灾,特别是对航空部门有很大的影响。
