查询词典 light source

2Nd, thorough analysis: The Earth may say is an extremely marvelous thermonuclear reactor, when the earth interior pressure achieved certain critical, in the Earth material may decay the nuclear matter is called as the thermonuclear material, can have the thermonuclear reaction, thus has the huge energy, then the melted partial materials, form the rock magma are the liquid state materials, this response stratification plane is possibly many stratification planes, first possibly is located between the earth's crust and the mantle, upward next two transfers, displays for the light density material diastrophism as well as density upper mantle material phenomena and so on solidification; Under second possibly is located between the mantle and the core, the pressure is more formidable, causes not not easily to have the thermonuclear reaction thermonuclear material to have the response, forms the relative quite stable liquefied material level, simultaneously is upward next two transfers, forms the counter-flow phenomenon which the high density under mantle as well as the high density core material contact liquefies and is far away cools; These material periodicity regular movements and so on convection as well as Earth polar axis rotation are possibly the basic source powers which the terrestrial magnetic field produces.

深入剖析：地球可以说是一个非常奇妙的热核反应堆，当地球内部的压力达到一定的临界，地球物质中可衰变的核物质统称为热核物质，就会发生热核反应，从而产生巨大的能量，进而融化部分物质，形成岩浆即液态物质，这个反应层面可能是多个层面，第一层可能位于地壳与地幔之间，向上下两边对流，表现为轻密度物质的地壳运动以及中密度上地幔物质的固化等现象；第二层可能位于下地幔与地核之间，压力更为强大，引起不易发生热核反应的热核物质发生反应，形成相对比较稳定的液化物质层，同时向上下两边对流，形成中高密度的下地幔以及高密度地核物质的接触液化和远离冷却的对流现象；这些对流以及地球极轴自转等物质周期性规律性运动可能是地球磁场产生的根本源动力。

Water-rock interaction demonstrates that, a gold-boring formation , i. e., a set of light metamorphic clastic gritstone, sandy slate, and tuffaceous slate in Wuqiang Runnel Formation, Ban Stream Group, act as the source of gold deposits in South-West Hunan. The gold is originally derived from volcanic eruption materials in Wuling-Xuefeng period; for the typical single gold deposit such as Mobin, which is short of sulphide, chlorine is very important in the metallogenic process; sulphur and chlorine perform as the major negative ions to form complex ions with Au throughout the gold activation and migration movement. The complex ion of chlorine and gold may keep stable in a wide range of temperature; the physical-chemical conditions in typical geothermal fluid system are of deciding significance for gold activation, migration and precipitation.

特定体系的水岩实验证实了漠滨及整个湘西南金矿的成矿元素Au和伴生元素主要源于赋矿围岩-板溪群五强溪组的一套浅变质碎屑砂岩、砂质板岩和凝灰质板岩；首次突破传统认识，证明氯在中低温热液体系中能与Au形成稳定络合物的形式进行运移，因此氯在本区Au成矿过程中起着相当重要的作用；成矿热液流体中Au主要以金硫、金氯络合物形式在溶液中迁移，阴离子∑S、Cl〓对金的活化、迁移及沉淀起主导作用，Au的伴生元素As、Sb在热液体系中与Au形成金锑、金砷络合物有利于金的进一步活化、迁移及沉淀；中低温热液流体成矿过程中，体系的物理化学参数对Au的活化、迁移及沉淀富集起决定性作用。

First of all , it is seen in Zhang Wei"s long writing that continuous changes occurs with the following era contexts which is shown. First, the gradual desalinization of " earth image " on the space," earth " is not only a creation in Zhang Wei"s novel, but the main source of the poesy of its works. It declines after " September fable ", not only indicating Zhang Wei "s decay of poesy of the novel, but also reflecting the disobeyed pross of light appear contemporary China social urbanization and common customs to . Second, the change of " writing subject projection " in the spiritual meaning, Its characteristic displayed by the reduction of image of spokesman as write thought representation .and on the other side represent" person who want more that resist actively " which also shows contemporary intellectual predicament and adjustment of value. Third, in " changeable and separate characteristics in the stylistics ",It changes " epic body " of" Ancient ship "," body not mythical " to " September fable "," pour out body " of" Bai Hui "" Family "," the discipline spreads the body "of Book of other provinces"," lie body " of" Can not recall the hollyhock ". Its constant changes persuing of recreation and sports, has entered into the different book mode and narration of different class gradually too.

首先，张炜的长篇写作中可以看出一种跟随时代语境而不断发生的变化，这表现在：一是空间上的"大地意象"的渐趋淡化，"大地"不但是张炜小说中的一个创造，而且也是其作品的诗意的主要源泉，它在《九月寓言》之后的衰退，不但表明了张炜小说中诗意的衰减，而同时也反照出当代中国社会城市化和世俗化进程的不可违拗；二是精神意义上的"写作主体投影"的变化，其特征主要表现为作为作家思想代言者的"正面的知识者"形象的弱化，代表其另一面的"积极反抗的多欲者"的凸显，这也显示了当代知识分子价值的困境与调整；三是在"文体上的多变与另类化"，由《古船》的"史诗体"，到《九月寓言》的"神话体"，再到《柏慧》、《家族》的"倾诉体"，《外省书》的"纪传体"，《能不忆蜀葵》的"诳语体"，其文体不断求变，也逐渐走入了异书模式和另类叙述。
