front surface field
解釋
前面場-
Through the thermodynamic analysis for the sandstorm weather according to the simulated potential temperature, potential vorticity field, it is found that this sandstorm weather occurred in the condition of the atmospheric stratification stability, the area of the high potential temperature value and the potential temperature gradient have a good corresponding relationship with the surface cold air and cold front, so are the strength of potential vorticity and the different developing stage of sandstorm
利用輸出的位溫、位勢渦度場，對沙塵暴天氣進行熱動力條件分析，發現本次沙塵暴天氣發生在大氣層結穩定狀態下，位溫大值區及位溫梯度與地面暖低壓的強弱和移動有著很好的對應關系，位渦的水平分佈特徵和強弱變化對沙塵暴的出現時間和落區有一定的指示意義。 -
In order to make the studying about the seismic exploration method possess systematic nature and the ability of tackling key problem in front - zone of mountain, we have done the research work of tackling key problem aiming at the field gathering technology of seismic exploration of the complicated structure belt ( the construction of underground and the earth ' s surface condition are complicated ) of front - zone of mountain in this text, and a large number of relativity trials by the close combination of production and scientific research, summarized a set of field method of the complicated structure belt of front - zone of mountain, adjusted both of trial factor and construction factor of the field gathering in time, achieved finally the goal of making its structure character clear
近幾年來，隨著地震勘探裝備和技術的改進，野外資料採集技術有了新的進展，主要表現為多種震源聯合激發方法（井炮和大噸位可控震源） ，基於地表條件及表層調查基礎上的激發選點方法，小道距、長排列、高覆蓋接收方法，基於模型的「分段、分線、分區」觀測系統目標設計方法等，取得了顯著的勘探效果。為了使山前地震勘探方法研究具有系統性和攻關性，通過本文對復雜山前復雜構造帶地震勘探的野外採集技術進行攻關研究，進行了大量具有針對性的試驗，總結出了一套山前復雜構造帶野外施工方法，最終達到了搞清復雜山前復雜構造帶山前復雜構造帶構造特徵的目的。
