seismic cluster 中文意思是什麼
seismic cluster
解釋
地震群-
The result show, most of the medium - strong earthquakes faults are dip - slip reversed, distribution of the main stress p axis is sector from west to east ; there are large difference between kuche and baicheng region in seismic activities, but the characteristic of cluster is same in the two region ; the distribution of medium - strong earthquakes is nw direction in baicheng region, it show, there can have a concealed fault ; small earthquake clusters ' activities can reflect the effect that local medium - strong earthquakes to the secondary small structure around it
結果表明：南天山東段中強震震源斷錯以傾滑逆斷為主，主壓應力p軸由西到東呈扇形分佈；相距較近的庫車與拜城地區地震活動存在較大差異，但均存在明顯的成叢性分佈特點；拜城地區中強地震分佈呈北西向可能預示著該區存在隱伏斷裂，小震群活動則可能反映了局部中強震對周圍次級小構造的影響。 -
Combining the result with logging, exploiting information, using multiple mathematics methods such as cluster analysis, neural network, step - by - step linear regress, the paper found the relationship among seismic, logging, and exploiting information in well - control zone. moreover, we calculate fracture richness index. as a result, we can distinguish rich fracture zone from carbonate formation by fracture richness index in non - well - control zone
結合測井、開發等資料，在有井點利用聚類分析、逐步回歸、神經網路等數學手段，建立了多種地震檢測結果與測井、開發等數據之間的定性、定量關系，計算出了研究區的裂縫發育指標，從而實現對無井區的縫洞預測。 -
This increases the accuracy for interpretation greatly. due to 5 / 6 wells are slant holes in developing cluster wellgroup, environmental corrections are made to acoustic logging data of deflecting wells. through synthesis seismic records, quasi - velocity is calculated and seismic calibration of deflecting data is carried out
對埕島油田館上段儲層微觀非均質從主要孔隙類型、孔喉分佈、孔隙與滲透率分佈、孔隙半徑的大小、孔喉比、孔喉配位數和面孔率等方面進行了定量評價。 -
Based on thorough analysing the factors which affect the seismic damage of single - story reinforced concrete industrial building, this paper introduces two kinds of methods which are applicable to prediction of seismic damage for single - story reinforced concrete industrial building. one is bp ( back propagation ) neural network method, which is based on the theory of artifical neural network. in this method, lm ( levenberg - marquardt ) optimization algorithm is applied to improve the performance of standard bp algorithm. the other is grey fixed weight cluster method, which is based on the theory of grey system
本文在充分分析單層鋼筋混凝土柱工業廠房震害影響因素的基礎上，提出了兩種用於單層鋼筋混凝土柱工業廠房震害預測的新方法。一種是基於人工神經網路理論的bp神經網路方法。在bp神經網路方法中，採用改進的bp演算法（ bplm演算法）對網路進行訓練，有效地改善了標準bp演算法的不足之處。
