The relationship between mantle fluid and U ore-forming was studied preliminarily,according to the results,the author considered theΣCO_2 of mineralizer and heat source came from mantle,which is because upwelling mantle forced by crustal extention and deep-seated faulting produced melt blending with lower crust,during this process,mantle provided the heat and releaseΣCO_2 to crust through outgassing.U mainly came from mantle-curst fluid formed by mantle-curst melt blending and the wall rock during fluid uplift.H_2O mainly generated from mantle fluid and the wall rock during mantle fluid uplift,and partly from atmospheric water in the late period of ore-forming.
初步探讨了地幔流体与铀成矿作用的关系,认为矿化剂∑CO_2和热源来源于地幔,是地壳拉张和深大断裂活动导致部分熔融地幔上涌,与下地壳产生壳幔混熔作用,在混熔过程中提供热量和向地壳&去气&释放∑CO_2;U主要来源于壳幔混熔形成的壳幔混合流体和流体上升途经的围岩;H_2O主要来源于地幔流体、地幔流体上升途经的围岩,在成矿晚期有部分来源于大气降水。

Vesic's solutions to cavity expansion that include cylindrical cavity expansion and spherical cavity expansion are introduced. Then cylindrical cavity expansion theory is applied to study compaction effect of pile driving in saturated soil. Based on the results of conventional triaxial tests, a trilinear curve model is used to simulate stress-strain curve of strain-softening materials. Meanwhile, trilinear curves are also used to simulate curves of volumetric strain, minor principal strain and major principal strain. By using elasto-plastic theory, analytical solutions to cylindrical cavity expansion in strain-softening soil are presented. According to the mechanism of statically pressed pile driving, compaction effect of pile tip can be viewed as hemispheric cavity expansion. Therefore spherical cavity expansion theory is applied to obtain the solutions to stress, strain, displacement fields and final pressure. Resistance force of pile tip is calculated to estimate static pressure.
介绍了Vesic关于圆孔扩张问题的解答,其中包括柱形孔扩张问题和球形孔扩张问题,并应用柱形孔扩张理论分析了饱和软土中的沉桩挤土效应问题;在常规三轴试验成果的基础上,采用三折线模型模拟具有应变软化性质的岩土材料的应力应变关系曲线,分析了在应变软化土体中沉桩时桩周土的位移场、应力场和应变场的变化,得到了解析解答;分析了静压桩的沉桩机理,并利用球形孔扩张理论,视桩端处的挤土为半个球形孔的扩张,分析了桩端处土的位移场、应力场和应变场的变化,并根据最终扩张压力计算出沉桩时的桩端阻力,可作为压桩力的估算。

Based on the settings and geological and geochemical characteristics of granitoids of different orogenic belts (exemplified by orogenic granitoids in Altay, East Kunlun, Yanshan in North China, Northeast China and Nanling in South China), the relationships between granitoids and continental crustal growth are discussed, and five modes of continental crustal growth in the continent of China are proposed;they are as follows:(1)the Altay mode of continental growth is that the material and heat of the Paleozoic convertive mantle formed on the background of the Paleo-Asian Ocean were input into the Paleozoic continent and mixed with the materials of the upper crust;(2) the East Kunlun mode is that the basement of the Proterozoic orogenic belt was reworked by the heat input and materials of the Paleozoic-early Mesozoic convective mantle formed on the background of TTG continental crust of the Proterozoic orogenic belt;(3) the Northeast China style is that the Phanerozoic continental crust was reworked by the heat input and materials from the convective mantle formed on the background of the Yanshanian Central Asian orogenic belt;(4) the Yanshan mode is that the Archean basement was reworked by the heat input and materials from the Yanshanian convective mantle;and (5) the Nanling mode is that in South China what was input by the Yanshanian convective mantle into the continent was mainly heat and subordinately materials and the crustal material recycle was the dominant mode for the continental growth (showing zero continental growth).
根据不同造山带花岗岩的形成背景,地质地球化学特征差异,以阿尔泰,东昆仑,华北燕山,东北和南岭造山带花岗岩为例讨论花岗岩与大陆地壳生长的关系,区分出中国大陆的5种大陆地壳生长方式:阿尔泰式是古亚洲洋背景上形成的古生代对流地幔物质,热输入和上地壳混合为主的方式;东昆仑式是元古代造山带TTG陆壳背景基础上古生代—早中生代对流地幔物质和热输入,改造元古宙造山带基底的方式;东北式是燕山期中亚造山带背景上对流地幔物质和热输入改造显生宙陆壳的生长方式;燕山式是燕山期对流地幔物质和热输入改造太古宙基底的方式;南岭式燕山期对流地幔输入大陆的是以热为主,物质为辅,大陆地壳生长是以陆壳物质再循环为主的生长方式。

mantle cavity:套腔
外套膜与内脏团之间形成的腔称外套腔(mantle cavity). 腔内常有鳃、足以及肛门、肾孔、生植孔等开口于外套腔. 外套膜由内外两层上皮构成,外层上皮的分泌物,能形成贝壳,内层上皮细胞具纤毛,纤毛摆动,造成水流,使水循环于外套腔内,

mantle cavity:套膜腔
以图五中的鱿鱼为例,其外套膜腔(mantle cavity)中充满海水,能保持一定的压力支持体壁. 外套膜腔以一漏斗形的开口(funnel)与外界相通,此一开口位於头的下方. 当鱿鱼游泳时,外套膜肌肉收缩,将腔室内的海水迅速经由开口排出,形成喷射的推进力,
