heterosphere n.【氣象學】非均質層。adj.-ospheric

heterosporous

Research area is characteristic of heterosphere obviously , which mainly manifests that distribution , thichness and extent of delelopping of sand body is not symmetrical . difference of transverse permeating rate is more 10 times than longitudinal permeating rate . the research indicates : the principle productive formation at this area is the member of h8x , h8s on the lower hezi formation that are good reservoir 研究區儲層非均質性明顯,主要表現為砂體分布不均勻、厚度不均,發育程度不一,滲透率縱橫向差異均在10倍以上等;儲層發育較好的層段是山西組山1段,是本區的主要產層;神經網絡技術對于儲層物性參數的預測是一種比較有效的方法;儲層綜合評價指數對于儲層的評價具有一定的理論和現實意義。

( 4 ) from computing the safety coefficient of homogeneous and heterosphere slopes , we can get useful conclusion that the safety coefficient change in the course of precipitation duration ( 4 )通過計算相同降雨條件對均質邊坡和成層土邊坡穩定的影響,得出安全系數隨降雨持時變化的曲線以及一些有益的結論。
