Where the product is at unusual risk of contamination from the environment, for example because the filling operation is slow or the containers are wide-necked or are necessarily exposed for more than a few seconds before sealing, the filling should be done in a grade A zone with at least a grade C background.

如果产品受到环境污染的风险高，例如：灌装速度慢，使用大口容器，或密封前要暴露几秒钟，灌装要在C级环境中的A级区域进行，背景环境最低为C级。

Joint stent and the use of microcoils is the treatment of intracranial wide-necked aneurysms safe and effective method, LEO stent dedicated intracranial self-expandable stent, To meet the intracranial vascular The tortuous road design, A stent in place easily, positioning accuracy can be controlled release merits.

LEO颅内专用自膨式支架，专为适应颅内迂曲血管经路设计，具有支架到位容易、定位准确、可控制释放优点，使支架辅助栓塞颅内宽颈动脉瘤更加安全、有效。

The chemistry compatibility of the electrode and electrolyte at high temperature and effects of the sintering temperature on the microstructure and electrochemical properties were investigated, respectively. The results showed the sintering temperature has effect on the polarization resistance of the electrode. At moderate temperature, a fine microstructure with moderate porosity and well-necked particles has been formed, and the electrode gave the lowest polarization resistance.

考察了电极材料与电解质材料在高温时的化学相容性；研究了烧结温度对电极的微观形貌及电化学性能的影响，结果表明，烧结温度过高或过低都会导致电极极化面电阻的增加，当电极的烧结温度适中时，电极表面粒子有一定的烧结连接，并且有一定的多孔结构，电极的极化面电阻达到最小值。

Dutar is a traditional long-necked two-stringed lute found in Central Asia and South Asia. Its name comes from the Persian word "dotar" for two strings (do "two", tar "string").

都塔尔是广泛使用於中亚及南亚地区的一种传统长颈二弦琴，它的名字来自於波斯文&dotar&，&do&为二、&tar&为弦的意思。

The method comprises: adding 4-(3,4-dichlorophenyl)-1-tetralone and solvent at a ratio of 1:(3-4) into a three-necked flask with a stirrer, heating under stirring until 4-(3,4-dichlorophenyl)-1-tetralone is completely dissolved, heating to 60-100 deg.C, refluxing for 0.5-2 h, cooling the filtrate to -5-10 deg.C, filtering, recrystallizing to obtain refined 4-(3,4-dichlorophenyl)-1-tetralone, and drying at 40-80 deg.C to obtain dry 4-(3,4-dichlorophenyl)-1-tetralone.

该方法的步骤是：在带搅拌的三颈瓶中依次加入4-(3，4-二氯苯基)-1-萘满酮和溶剂，溶剂与4-(3，4-二氯苯基)-1-萘满酮的L∶W为3～4∶1，将上述4-(3，4-二氯苯基)-1-萘满酮及混合精制溶剂搅拌下升温，使4-(3，4-二氯苯基)-1-萘满酮全部溶解，升温至60～100℃，回流0.5-2h；滤液用冰水冷却至-5～10℃，过滤，所得物料再用上述方法进行一次重结晶得到精品4-(3，4-二氯苯基)-1-萘满酮，40～80℃干燥后即得到干品4-(3，4-二氯苯基)-1-萘满酮。
