轻

When the cut of a diamond is too shallow, light escapes through the pavilion before it can be reflected.

当一颗钻石的减少穿过亭子是太浅，轻的逃离时，在它可以被反映出之前。

When an important diamond is shaped a man may spend a week …will split it exactly so.

当打造一颗重要的钻石时，一个人可能要花一周甚至几周时间去研究它，要集中所有的记忆、直觉和注意力，直到最后确定用恰如其分的轻敲力才会将原石准确地按需要分开。

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。

Aluminium material has some good characteristics, such as light weight,good diathermancy,good electric performance and so on.

铝材具有质量轻、导热、导电性能良好的特点。

It builds the whole liquid-cooling system mainly by the design of the liquid-cooling decalescence boxes(improve its bottom material from aluminium alloy to pure copper, enlarge its volume, better cooling effects, and strengthen pressurization), by the operations of cooling effect about the heat exchanger worked by its temperature adjustability of the ribs(diffuse the heat fleetly owing to the excellent diathermancy of the material of the ribs ,make effective diathermancy owing to ribs outside areas, and drive the heat of the ribs away by the fans), and by the water pump made up of the piezoelectric ceramic with the excellent performance-no electromagnetism interference, little cubage, little noise, light exterior, light weight, low consume, high flux, replacing the mechanical pump.

在液冷散热器的研究中，主要通过对液冷吸热盒设计不断地改进(使吸热盒底部的材料从铝合金变为纯铜材料，其整个体积有所变大，但其散热效果明显变好，且密封性得到了极大地加强)，综合地运用换热器中肋片的壁面温度调节作用产生的散热效果(肋片材料优良的导热性，快速地扩散了热量：肋片较大的与流体接触的表面积，使传热更加充分，对流热阻大大减小；再利用风扇对肋片上的热量进行吹散)，利用性能优良的压电陶瓷泵(该泵机电性能稳定，具有无电磁干扰、体积小、噪音小、外型轻薄、重量轻、低能耗。、高扬程等优点。)代替机械泵作为驱动源，搭建了整个散热系统。
