地表物质中宇宙成因核素浓度除了受到核素生成速率和地表物质的暴露时间制约外，还与地表侵蚀速率密切相关，此外，地磁场强度、遮蔽、化学风化及样品的几何位置等也会对核素浓度产生一定影响，在求算样品的地表暴露年代时，应对这些因素进行相应的校正。

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。

我们懂得，不断晒的工艺是不兵感光片呼到草稿框的玻璃上来与草稿片基精密隔绝曝光，曝光完后撤废假不满，不兵感光片呼下再进不静下一晒。

The thickness of bovine liver in vitro ranged from 4 to 10 cm. Ultrasound energy was continuously delivered to ablate the liver with a frequency of 1.6MHz, and spatial peak pulse average acoustic intensity of 12000 W/cm^2. The characteristics of complete coagulation necrosis and exposure time were measured after FUSC exposure, and pathological changes in treated bovine liver tissue were observed.

在超声频率为1.6MHz，声强12000W/平方公分条件下，对厚度4~10cm离体牛肝进行双面连续扫描辐照后，记录牛肝达到贯通性凝固性坏死的辐照时间，测量离体牛肝凝固性坏死性状的形状和特征，观察组织病理学的变化。
