First, we found that after exposure to 60℃ for 5 and 30 min ,culturable L. pneumophila concentration reduced 4 and 6 log CFU/mL, and the loss of cell membrane integrity was 56 % and 83 %, respectively. However, the total concentration was not affected. These results indicate heat exposure decreases the culturability of L. pneumophila significantly.Second, heated L.

结果显示，退伍军人菌（108 cells/ml）於60℃受热5分钟与30分钟后，可培养浓度分别下降了4 log CFU/ml与6 log CFU/ml，而细胞膜完整性则分别下降56 %与83 %，但未造成总细菌浓度之改变，故可知受热60℃主要影响细菌的可培养性。

The video which is part of the hospital's Infection Prevention drive which has already seen cases of MRSA drop by more than 60 per cent and C. difficile by over 50 per cent in the past 12 months.

这个视频是医院感染预防项目的一部分，这个项目在过去12个月中，已经使该医院的耐甲氧西林金葡菌病例下降了超过60%，难辨梭菌病例下降超过50%。

Over time and with the past 30,000 years of repeated history, so many discarnate humans continuing in an afterlife were taking so much of Earth's chi that Earth has continued to descend and descend in vibration.

随时间，过去30，000年重复着历史，如此多脱离肉体的人类继续在一个夺获着地球如此多的 chi 的来生中，以至于地球的振动下降了再下降。

The effects of many factors in the wet end on drainage and retention of PEO/attapulgite system: During the scope of 2-12, pH has no effect on drainage, and retention ratio lower in acidic conditions and higher in neutral or alkaline conditions. There were some improvement on slurry's drainage and some impairment on retention efficiency for the existence of inorganic salts. Lignosulphonate had no effect on drainage and made retention ratio decrease 5-8%; lignosulphonate and xylan had no effect on drainage and made retention ratio decrease a little. 5 .Attapulgite could be modified by intercalation.

纸机湿部系统的影响因素对PEO／凹凸棒粘土助留体系的助留助滤效果的影响表现为：pH值在2-12范围内，对助滤效果是没有影响的，使助留效果在酸性条件下较差，而在中碱性条件下较好；无机盐的存在使浆料的滤水性能有一定的改善，使助留效果有所削弱；木质素磺酸盐对助滤效果是没有影响的，使留着率下降了5—8％；木质素磺酸盐与聚木糖对助滤效果也是没有影响的，使留着率略有下降。

The results showed that there existed significant difference in RAPD between different biotypes as well as among individual BPHs, and genetic purifying could lessen this difference in the level of individuals but not in the level of biotypes.

结果发现：家系纯化对褐飞虱个体及生物型1和生物型2群体的致害力均有影响，个体间存在的致害力差异有所减小，但未能消除；两种生物型群体的致害力均显著下降，至第五代时对感虫对照TN1的致害力已分别下降了23%和16%，然而各自的致害特征并未发生根本性的变化，表明它们的致害特性是相对稳定的。
