The lack of consistent high Poisson′s ratio (≥0.30) shows that widespread partial melt does not exist within the curst, but does not exclude the presence of local partial melt.③There is an obvious thickened zone of the mantle transition zone compared with IASP91 standard value which varies from 10 km to 26 km in Qiangtang terrane. The anomaly suggests that the temperature is about 100 ℃ to 260℃ lower than global average value within the mantle transition zone, and it may be attributed to the presence of a subducted slab within the mantle transition zone.

缺乏高的泊松比(≥0.30)分布表明青藏高原东南缘的地壳不存在广泛的部分熔融，但是不排除局部部分熔融的存在；③青藏高原东南缘的羌塘地体内存在一个比较明显的、异常变化范围为10～26 km的地幔过渡带增厚区域，其对应着地幔过渡带内100℃～260℃的温度降低，可以推断与此异常区域的地幔过渡带内存在俯冲的板块有关。

In order to get reasonable prediction, 6 km modelgridresolution and 18 km accuracy of orography are needed.

为了得到公道的模拟，6km 的模式分辨率和18 km 的地形精确度是必须的。

Based on the data of 5 years in 1970s with duct present and those of December 1990, refractivity at height of 1 km, the average gradient of refractivity and surface refractivity are obtained by regression of the refractivity profiles to exponential models. And it is found that the constants in the exponential relation of refractivity of 1 km above ground and the mean vertical refractivity gradient in the first kilometer height with the surface value of refractivity are 110.6, 0.002 9 and -8.6, 0.004 7 respectively according the data of the 1970s?
