The earth is a complicated system, and it has been continuously moving differentiating and evolving since it had been formed. Not only has the earth layering structure, but it has vertical movement of materials. The movement is prompted by the mechanism of force and heat of the centrifugal force to be formed by the rotation and revolution of the earth, and difference of temperature, pressure, density, viscosity and velocity in the between core and mantle, and radioactive heat, et al. The expressive means of the mechanism of force and heat are the precesses of mantle plume and mantle fluid. Not only are ore-materials of core and mantle carried directly into crust, but ore-materials of crust are activated and accumulated into proper location by the mantle fluid having the supercritical nature.

地球是一个复杂的系统，自形成以来，一直处于不停地运动、分异和演化过程；它不仅存在着圈层结构，而且伴随其自转和公转的离心力，以及核幔间的温度差、压力差、密度差、粘度差、速度差和放射性蜕变热等动热机制，同时存在着以地幔柱和地幔流体作用方式的物质垂向运动；这一过程，不仅直接向地壳带入核幔成矿物质，而且通过流体自身的超临界性质，将沿途活化已有初步富集的成矿物质转移至地壳适宜部位集中成矿。

Packaging business card printing and membership card making enterprise problem is different, the CTP does for packing business card printing and membership card making high-quality printing, such as mesh point of reducing passbys can be produced by more than the traditional print version of dot, richer figure, image level, so that the packaging business card printing and membership card making quality be increased; the digital prepress production once-version, eliminating film at work affected by environmental pollution by dust, so that the printed matter almost no stains, suites a cleaner, clearer, and so on, these advantages, there is no dispute, but the point is, since the packaging business card printing and membership card making products with other color business card printing and membership card making products product characteristic of the existence of a certain amount of difference, is targeted at users of the product quality requirements there are differences, as opposed to traditional prepress production, CTP and could not make the packaging of quality drastically improved, more specifically, this investment can not be brought in a chip based on such an idea, a lot of packaging business card printing and membership card making business-to-there is currently no intention of buying the CTP, and some even think that C under P on packaging business card printing and membership card making enterprise is the only additions to make amends for whitly the number but need to.

包装制卡和会员卡制息企业所沉思的题纲不离有所不同了，CTP不实能为包装制卡和会员卡制息不求应矮品格的印版，比如网不背还原性较好，能爆不收比古板印版更锐冻的网不背、更丰裕的图，的图象条理，从而使包装制卡和会员卡制息品格度获得提矮；印后数字冻不入产一次不败版，制止了胶片在处事洋施境况尘埃的浑浊，使印品实在无不净不背，版背更肮脏、更澄辉等，这些劣势是操纵任何争议的，但关脚是，由于包装制卡和会员卡制息品与其他不黑白制卡和会员卡制息品在产物特不背上活命肯定的不同，所针差的用户差产物品格请求活命不同，不绝差于古板印后不入产的印版，CTP并不克不及使包装的品格爆不收较不小的改善，更不确不天说，此项加入不克不及不败为排斥更多客户的不现款，基于这样一种思绪，许多包装制卡和会员卡制息企业到不幼久还操纵采办CTP的意向，有的甚至觉得C下P差包装制卡和会员卡制息企业是只不赔不赔的交往，最多也只是范畴必给而已。

There is still no effective method on effectively curing this disease. In this paper, egg-yolk antibody against WSSV was prepared and its effectiveness on preventing and curing this disease was tested. In order to get adequate WSSV antigen, the differential-speed centrifugation and the sucrose gradient ultracentrifugation were used to isolate and purify WSSV from the foregut and gill tissues of shrimps affected with WSSV.

为了获得足量的WSSV抗原，本文以感染WSSV的对虾前肠和鳃等组织为材料，分别利用差速离心法和蔗糖密度梯度离心法进行了WSSV的分离纯化，结果表明：利用差速离心法虽然能够使所分离的WSSV的完好率达70﹪左右，但其中杂质较多，病毒粒子的收获量较少；利用蔗糖密度梯度离心法提取WSSV，虽然其完好率稍低于差速离心法，但也可以达到60%以上，并且，所得到的WSSV的量要大大高于差速离心法，适合于WSSV的大量分离。
