由此发现，在运载层物性不变的情况下，天然气沿上倾地层向上倾方向运移的过程，是随地层温度和压力不断降低、其运移速度逐渐增大的过程，如果有后续气体的加入，会使气体长度增大，致使运移速度增加得更快。

The south and north of the windward side of the Annam Cordillera show great difference in the diurnal variation of rainfall, which is related to migration of rainfall. Rainfall over coastal areas of the Thailand Gulf in 01-04LST migrates to inland northeastwards and then heavy rainfall occurs over areas southwest of the Annam Cordillera in 16-19LST, after that heavy rainfall migrates northwestward along the Annam Cordillera to areas northwest of the Annam Cordillera in 01-04LST in the next day. The migration of rainfall results in different characteristics of diurnal variation on the windward side of Annam Cordillera.

长山山脉西侧迎风坡的一南一北两个区域，表现出明显不同的降水日变化特征，其原因与降水的传播有关。01-04LST，降水大值区出现在泰国湾东部沿海，并向中南半岛岛内传播，16-19LST在长山山脉西南侧形成降水大值区，之后降水进一步沿山脉向西北传播，并于次日01-04LST传到长山山脉西北侧区域，通过降水的这种传播特征从而导致长山山脉迎风坡一侧不同的降水日变化特征。

Thirdly, according to the development of the frozen soil, the coupling model of single freezing pipe of axial symmetry of temperature field, stress field and moisture migration is put forward firstly. Then, by means of the progressing principle of potential field, the coupling model of temperature field, stress field and moisture migration which is under the condition of the multi-freezing pipes is extended. At last, the energy balance equation, stress balance equation, quality balance equation, geometric equation, physical equation, initial and boundary conditions etc are adopted to give the analytic solution to the problem of plane axial symmetry of single freezing pipe.
