To describe the anisotropy of microdamage of the crust block, we use the damage tensor that is expressed in the fissure density
為描述地殼塊體微損傷的各向異性，引入裂紋密度表示的損傷張量形式。 -
The macroscopic damage status of the earth crust block, which is caused by earthquake fracture, is described with several concepts - the damage degree, the damage rate and the strain rate
對地殼塊體由地震破裂引起的宏觀損傷狀態，通過引入損傷度、損傷率? 、應變率?來刻畫。 -
The reason for the moderate and large earthquake of zhengjiang block could be attribute as such features : because of the structure ' s more rigidity and the rising of the several interfaces in the crust, the energy from the deep crust of upper mantle is transported to the middle or upper crust persistently. thus it always accumulates at some locations and this may lead to eart
由於地表火山活動的停止，來自中下地殼和上地慢的大部分能量得不到釋放，從而在有利的構造部位積聚，進而在流體的作用下，或在其它外動力誘發下，導致孕震系統失穩而發生地震。 -
Different zone block in the basin has different construction. cold and heat shells are at intervals. crust behaves as hot, light, flowing and thicker, however, mantle behaves as cold, weight, and harder, multi - phase and deep mantle
盆地不同區塊熱結構不同，為冷、熱殼相間，地殼表現為熱、輕、軟、流、厚殼，地幔表現為冷、重、硬、多相、深幔的特點。 -
All of the mafic samples have age - corrected moderate enriched sr and enriched nd isotopic ratios and the felsic rocks span larger range in the initial sr and nd isotopic ratios than mafic volcanics, similar to isotopic compositions of lower crust of north china block
在sr - nd同位素組成上，中基性火山巖為中等富集的sr和低的nd同位素比值；中酸性火山巖的sr同位素比值總體較中基性巖高且變化大，類似華北陸塊下地殼巖石的同位素組成特徵。 -
Based on the regional geologic survey on the scale of 1 / 250 000, coupled with geological, geochemical and geophysical investigations in some key regions, this dissertation summarized the tectonomagmatic evolution and mineralization of the mid - gangdise area. with respect to tectonic evolution, the gangdise belt has experienced a multi - stage evolutional history since mesozoic, including oceanic crust subduction, arc - continent collision, intracontinental subduction and collision, and strike - slip and block uplift
論文以新一輪1 ： 25萬區域地質調查為基礎，在對關鍵區段重點解剖的基礎上，結合地球物理、巖石化學、地球化學、沉積作用、變質作用、構造演化和成礦作用的研究成果，對岡底斯中段的構造巖漿演化與成礦作了較系統的科學總結。 -
Continent block colliding during late - permian to middle - triassic ; lower part delamination and upper part rifting of lithosphere during late - triassic ; delayed compression and uplift during early - jurassic ; crust extension from middle - jurassic to early - cretaceous ; large - scale strike sliping from late - cretacoues to present. ( 6 ) roughly expounding the deposits distribution feature in south part of sanjiang orogenic belts, especially in detail to set forth the characters of southern nanchangjiang cu, pb, zn, ag, sn, fe metallogenic belt
初步闡明了三江造山帶南段礦床的時空分佈特徵，特別是較系統闡述了與巖石圈拆沉作用相關的南瀾滄江cu 、 pb 、 zn 、 ag 、 sn 、 fe成礦帶的特點，指出含鉀較高的火山巖可作為尋找拆沉環境中銅多金屬礦的有利地區，而火山巖中孔隙度較高的層位、層面和破碎帶可作為優先找礦部位。
