查询词典 vitrify

This invention discloses a new technology for preparing rear earth ionic doped fiber prefabricated rods with DC-RTA technology in a sol-gel method including preparing sol containing necessary doped ions, coating said sol uniformly on the inner wall of the quartz glass tube and burning it under high temperature to coagulate and vitrify them to a doped layer and repeating the above process to form a fiber prefabricated rod by oxygen and hydrogen flame after the doped layer reaches to a designed thickness and the fiber prefabricated rod can be made to various rare earth ionic doped fibers by an ordinary drawbench technology.

本发明属于光纤制造和光纤激光技术领域，具体公开了一种利用溶胶凝胶方法中的DC-RTA技术制备稀土离子掺杂光纤预制棒的新工艺。该工艺步骤包括预先配制好含有所需掺杂离子的溶胶，将该溶胶均匀涂覆在石英玻璃管的内壁后高温灼烧，使之凝结并玻璃化为一层掺杂层。反复上述涂覆灼烧过程，在掺杂层达到设计厚度后由氢氧焰高温收棒形成光纤预制棒。该方法所得到的光纤预制棒可以通过普通拉丝工艺拉制成各类稀土离子掺杂光纤。

in this paper the basic concept to literality technology is introduced,and the application of vitrify technology in high university teaching resource management, multimedia teaching effect, and experiment teaching method and virtual instrument equipment.

摘要本文介绍虚拟技术的基本概念，重点介绍了虚拟技术在高校教学资源管理、多媒体教学资源教学效果和实验教学方法以及虚拟仪器方面的应用，论述了高等学校教学资源重塑信息共享及管理模式和虚拟实验教学解决方案，提出了高校教学改革与研究的新理念。

Form of pottery fired at relatively low temperatures, so that the clay does not vitrify, as do stoneware and porcelain clays.

有时做为所有pottery的总称，它烧制时温度较低，所以制陶的泥不象石器和瓷器那样光滑。

"Earthenware is the oldest and simplest form; stoneware is fired at a high temperature to cause it to vitrify and harden; and porcelain is a fine, generally translucent form of pottery ."

陶器是最古老和简单的陶瓷形式，而石陶器则是在高温下形成的玻璃状硬器皿，瓷器则是一种精致半透明的陶瓷。

Based on reviewing the banking reform experience of Eastern European countries, we propose seven propositions on China's banking sector reform and empirically vitrify seven propositions using data from 21 banks between 1999 and 2006 ,then draw final conclusions: foreign banks entry lower the profit rate of hosting country banking industry in short-term, improve host country banking's risk management skills

本文在综述东欧国家银行业改革经验的基础上提出中国银行业改革的七个命题，并用中国24家银行1999-2006年间的数据构建模型进行检验，最后得出结论：短期内外资银行进入导致东道国银行业利润水平下降、风险管理水平上升，在中国的背景下可以认定这是外资银行积极作用开始发挥；外资银行机构数量的增加和持股比重的上升都能刺激中国银行业效率的改进，但是外资银行持股比重的影响更具普遍性；不同类型银行对外资银行进入的反应存在差异，国有商业银行反应比较迟钝而股份制和城市商业银行反应比较迅速。

The method of vitrification cryopreservation of mouse 2-cell embryos was studied. Several vitrification solutions named EFS30, EFS40, EDFS30 and EDFS40 were prepared. The solution contains ethylene glycol, Ficoll, sucrose and DMSO. Straw method was used to vitrify and cryopreservate in vivo mouse 2-cell embryos at room temperature (20℃ or 25℃). OPS method was used to vitrify the embryo at 25 ℃ or 37℃.

本试验以毒性低、渗透性较强的乙二醇和DMSO为主体，添加聚蔗糖、蔗糖配制的玻璃化溶液(EFS30、EFS40、EDFS30和EDFS40)，在室温(20℃和25℃)下利用细管法，以及在25℃和37℃恒温台条件下OPS法对小鼠2-细胞胚胎进行玻璃化冷冻保存，并对解冻后胚胎的体外培养、囊胚细胞计数及胚胎移植技术进行了研究。

Subsequently,with the straw and the cell freezing tube,we usedone-step and two-step method to vitrify the embryo of Lats gene knockout mice.The development ratio reached 90% 90.1 % 89.2%, 91.4% and the implantation rauo reached 50.0%, 47.1% 43.4%, 46.5% respectively after thaw.

在此基础上，用冷冻麦管、细胞冷冻管分别采用一步法、二步法对Lats基因敲除小鼠胚胎进行玻璃化冷冻，胚胎解冻后，囊胚发育率分别为：90％、90.1％、89.2％、91.4％；移植后着床率分别：50.0％、47.1％、43.4％、46.5％，差异不显著；并且与对照组相比差异也不显著。

PartⅡFeasibility of vitrifying normospermic samples using droplets without cryoprotectans Objective Discuss the feasibility of droplets to vitrify normospermic samples without cryoprotectants. Methods Normal prepared sperm were frozen by conventional freezing protocol and non-cryoprotectant freezing in droplets respectively. Freezing in droplets means freezing sperm in every 10ul drop. After thawing, compared the two groups'sperm mobilities.

第二部分微滴法无保护剂玻璃化冷冻正常精子的可行性探讨目的探讨在不添加冷冻保护剂的情况下微滴法玻璃化冷冻正常精子的可行性方法收集16份正常精液标本，上游处理后分别进行慢速冷冻和微滴法冷冻，微滴法即用拉细巴氏管将标本形成10ul的液滴，直接投入液氮内冻存，复苏后镜检其活动率。
