Based on an integrated analysis of the surface geological, aeromagnetic, gravity, mt and seismic data from the area of mangnai to serteng mountains in the western qaidam basin, the authors think that the qaidam basin is sandwiched between the north kunlun block and serteng tectonic belt, including two first - order tectonic units the qaidam block and the southern margin of the qilian block and four second - order tectonic units the northern margin of the north kunlun block, qaidam basin, serteng tectonic belt and suhai lake basin in the south of the qilian block
摘要通過柴達木盆地西部茫崖賽什騰山地表地質、航磁、重力、大地電磁測深和地震資料的綜合分析，認為柴達木盆地夾持在昆北地塊與賽什騰構造帶之間，其中包括柴達木地塊與祁連地塊南緣2個一級構造單元和昆北地體北緣，柴達木盆地，賽什騰構造帶和祁連地塊南部的蘇干湖盆地等4個二級構造單元。 -
By comparing with stochastic structural analysis, relations between the two methods have been found. the response surface method is used to obtain the second order estimates of the calculated results bound. by means of viscoelastic stochastic finite element method, the instantaneous reliability, the first passage reliability and fuzzy reliability of srm grain are investigated
採用凸集合模型表示藥柱參數的不確定性，在粘彈性有限元攝動分析基礎上進行了結構的響應區間計算，討論了概率方法和集合理論模型得到的響應區間之間的關系，利用響應曲面法進行了區間的二次估計。 -

It is well known that the coupled interactions between the ship hull and the surrounding fluid field of explosion give rise great influence to both the fluid loadings over the structural wetted surface and the responses of the hull. jt is the coupling effect that provides the major difficulties in the underwater explosion induced dynamic responses of the ship structure. the second order doubly asymptotic approximation method ( dda2 ) has been commonly employed in the world to deal with the coupling effect
本文針對daa方法不適合於分析敷有聲阻抗與水差不多的聲學材料（如玻璃鋼與消聲瓦）的船體結構與水下沖擊波相互作用的局限性，依據聲波的反射和透射原理對二階daa方法的高頻段進行了改進，發展並提出了能夠分析聲學材料流固相互作用的adaa方法（ acousticdaa ） ，拓展了應用范圍，使現有的二階daa方法成為它的一個特例。
