陆壳

This paper introduced some specialties of shell-tube-styled water-cooled condensers in marine air-conditioners, especially analyzed the differences of this kind of conducer from that on land in such aspects as the material of heat exchange tube, design structure, rot proof technics and the effect of incrustation, etc.

介绍船用空调装置中壳管式水冷冷凝器的特点，着重分析了其冷凝器在换热管材质、设计结构、防腐工艺、水垢的影响等方面与一般陆用空调冷凝器的区别。

In the late age of early ordovician to mid-late ordovician ,the qilian ocean crust begin to subduct northwardly and a typical trench-arc- basin system come into being.The Helan area become an extensional faulted depression influenced by the regional compressive stress and the Xiangshan area is the back arc basin of the north Qilian island arc.

早奥陶世晚期一中晚奥陶世，祁连洋壳开始向北俯冲，在北祁连地区形成了较完整的沟—弧—盆体系，贺兰山地区在挤压应力下断陷加剧，为一裂陷盆地，香山地区位于弧后盆地的靠陆一侧，鄂尔多斯盆地西缘地区为贺兰裂陷盆地的东侧斜坡。

Any of numerous aquatic or terrestrial mollusks of the class Gastropoda, typically having a spirally coiled shell, broad retractile foot, and distinct head.

蜗牛：腹足科众多水生或陆栖软体动物中的一种，通常带有一螺旋似的厚壳，足宽且向内旋，脑袋清晰

The granite plutons related to metallogenesis of iron mostly formed from 410Ma to 400Ma, resulted from the melt and differentiation of oceanic crust in a arc-continent setting because of subduction of plate.

与铁矿成矿有关的花岗岩多在410～400Ma形成，也是陆缘弧环境中板块俯冲作用下洋壳熔融、分异的产物。

Diamonds began growth when "Jiangnan continent" combined to Yangtze craton, the growth and residence average temperature T〓 was about 1200℃; Diamonds were mutil-stages growth and interruption caused by temperature and pressure varied during Yangtze craton activities; Diamonds were etched when the magma did not erupt on the surface and form failed magma in mantle; during the later growth term T〓＜1050℃, the type ⅠaA diamonds formed unclear and growth; Before the host magma erupted T〓＜0.5Ma, T〓A＜850℃, the type Ⅰb diamond formed unclear and growth; Few diamonds were brittle deformation during growth term, some were plastic deformation after growth; when the host magma erupted on the surface and weathered to alluvial deposit, diamonds surfaces formed green spots caused by irradiation, then most of green spots became to brown spots during a mid-temperature metamorphism; modern river reform it to alluvial deposit in the minute valley again.

在扬子地台&江南古陆&克拉通化时，金刚石开始生长，其生长与保存的平均温度T〓在1200℃左右；期间由于地台的活动，生长的温度压力条件发生了多次变化，使金刚石出现多次生长、停顿；夭折的母岩上侵活动使金刚石受到熔蚀作用；在金刚石形成的晚期，T〓值下降到1050℃以下，出现了另一次金刚石的生长期，在临近金刚石母岩上侵时T〓＜0.5Ma，温度进一步降到850℃以下，使Ⅰb型金刚石得以保存；在金刚石形成期间还有过碎性变形发生；金刚石形成后部分样品经过了塑性变形；金刚石在上侵过程中，遭受了强烈的熔蚀；在母岩露出地表，形成沉积砂矿时，受到了放射性物质的辐照，先形成表层的绿色斑点、壳层，后经过中低温的热变质作用，大部分绿色转化为褐色；现代河流作用对沉积砂矿进一步改造，形成现在的细谷型砂矿。
