There is no logical explanation for the vitrification of stone forts and cities , except from an atomic blast 除了核爆炸之外，并没有其他对这些石头保垒和城市的玻璃化的合理化解释。
Experimental investigation on cryopreservation method of human fetal skin specimen by vitrification in construction of tissue - engineered skin 组织工程皮肤构建中胎儿皮肤标本玻璃化冻存的实验
The pottery of the bronze age comprises a continuation of the earlier cord - impressed and geometric traditions and a new type of ware , fired at a much higher temperature leading to vitrification 青铜器时代的陶器，除了保留早期绳纹和几何印纹的传统外，还有一种经过较高火候烧制而接近结晶的硬陶。
Vitrification and encapsulation - dehydration are two new techniques and may have significant potential in the cryopreservation of some species of algae due to the limitation of the two - step freezing method 由于两步法保存技术的局限性，玻璃化和包埋脱水法等新技术在某些藻类的种质保存中可能有较大的应用潜力。
Certainly in the frames of the law and policy , this is a grey area . as china ’ s legal system deepening , especially after china ' s joining wto , vitrification of this grey areas will be necessary 在法律和政策的框架内，这是一个灰色地带，随着法治进程的深入，特别是中国已经加入世界贸易组织，这个灰色地带必将阳光化。
In our report , we selected trehalose to substitute sucrose in the cryoprotectant . the process of vitrification is under the same preferable condition . the survival - rate of the recovered cells was tested by fda - pi and cd34 + cell - count 冻融后的细胞以fda - pi双荧光染色、流式细胞仪cd34 +计数等检测手段，与同样条件的60蔗糖保护剂处理的细胞相比较。
A comprehensive research was conducting on the relations among its solidified behavior , vitrification point , adhesive power , impact strength and peel strength . the best solidification conditions of conducting electrostatic coating was established . 研究了导电涂层固化行为与玻璃化温度、附着力、冲击强度和剥离强度之间的关系,确立了导电涂料的最佳固化条件。
The survival - rate of the recovered cells was tested by mtt and fda - pi . therefore , we got the preferable condition of vitrification , i . e . , the concentration of cryoprotectant is 60 % and the time of disposal is 15min . under this condition , the value of fda / pi is 46 . 43 冻融后的细胞经过mtt检测和fda - pi双荧光染色法检测，获得预处理过渡的优化条件，即60浓度的保护剂，预处理15分钟，此时的fda pi值为46 . 43 。
In the 2 - step ops method , embryos were pretreated with 10 % eg + 10 % dmso for 30s before exposed to edfs30 , a vitrification solution , for 25s , then immersed in liquid nitrogen . the blastocyst rate of vitrified mouse morula after equilibration in 0 . 5mol / l sucrose for 5min was 100 % Ops二步法即胚胎预处理30s ，然后移入edfs30冷冻液中平衡25s冷冻保存，解冻后在0 . 5mol l蔗糖溶液中平衡5min ，培养后囊胚发育率为( 100 ) 。
Cryopreservation by vitrification is a kind of biotechnology sprung up in 1980 ' s . it is superior in simple - equipment and facilitated - operation . vitrification refers to the physical process by which concentrated cryoprotectant and cells treated are totally vitrificated into a ice - free and homogenous state 玻璃化法是指受高浓度复合保护剂处理后的细胞连同保护剂本身都进入一个均一的无冰晶的玻璃化状态，冰冻保存的细胞受到损伤较小，存活率较高。
