The tomographic result shows that there is a P wave low velocity zone ( LVZ) in the upper crust beneath the Tengchong volcanic area. The LVZ is in the depth of 7~ 8 km and may be a small magma chamber or a partial melting body.

A LVZ occurs in the middle crust, and a little change of velocity ( 6. 5~ 6. 9km/ s) exists in the lower crust.

中层地壳中有低速层出现；下层地壳的速度变化不大，约为6.5～6.9km／s。

Expounded that the RG values in common-used two-step static corrections method represents the statics of relatively fixed datum in equivalent LVZ;

阐明当前常用的两步法静校正中的RG值代表等效低速带相对固定基准面的静校正量；

Conventional methods that are on basis of refraction arrival time or microlog cannot yield proper LVZ velocity or static quantities in areas with complex near surface conditions.

常规的（基于折射波到达时或者微测井等）方法在复杂近地表条件下很难求得正确的低速带速度和静校正量。

The zero point of t 0 value corresponds to top interface of equivalent LVZ after application of the high-frequency components of statics to seismic data;

对地震数据应用静校正高频分量后，t0零点对应于等效低速带的顶界面；

This paper presents an approach that derives LVZ velocity and static correction values from the arrival time of first break by using tomography technology.

理论模型试验结果表明利用层析成像技术可由初至波的到达时反演表层低速带速度并求得静校正量。

In the top of LVZ and forming proliferation 'the second hot spots'.
