As the DDP group A549DDP cells were treated with IC10 of cisplatin for 48 hours. As the DDP＋Rh2 group A549DDP cells were treated with IC10 of cisplatin and IC5 of gensenoside Rh2 for 48 hours. As the controlling group A549DDP cells were not treated with any kinds of drugs. Changes in cellular morphology were observed by fluorescence microscopy. Peak value apoptosis of A549DDP cells were inspected by flow cytometry. State of PTP was evaluated by ultraviolate spectrofluorometer. Changs of calcium in cells and membrane potential of mitochondrion were determined by flow cytometry. Release of cyt-c from mitochondrion with westton blot Radiative activity of〓Tc-MIBI ingested by cells was measured withγcounter. Results: IC50 of cisplatine to A549 cells was 24uM.

以无毒浓度的Rh2单独作用于A549DDP细胞作为Rh2组，以低效浓度的顺铂单独作用于A549DDP细胞作为DDP组，以无毒浓度的Rh2和低效浓度的顺铂联合作用于A549DDP细胞作为Rh2+DDP组，作用时间为48小时，以不加药物干预作为对照组，Hoechst33258染色荧光显微镜下观察细胞形态的变化，流式细胞仪检测细胞凋亡峰；紫外光分光光度计检测线粒体PTP开放情况，流式细胞仪检测细胞内钙离子浓度及线粒体跨膜电位的变化，Westton blot检测线粒体内细胞色素C释放情况及Caspase-3的活性，γ计数仪检测细胞摄取〓Tc-MIBI放射性活性。

Environmental pollution accounting system is a complete set of theoretical method about the accounting of environmental pollution in physical-volume and value as well as the conceptions, methods, classific.

环境污染核算是环境与经济综合核算，即绿色国民经济核算的一部分，是对水污染、大气污染、固体废弃物污染、放射性污染和噪音污染的实物量和价值量进行核算的总称。

This article constructed a dynamic radionuclide transfer model of ecosystems on the theoretical basis of compartmental analysis.

本研究使用库室模型或'隔舱模型'方法建立描述海洋生态系统动力学微分方程组和放射性物质在生物体内行为微分方程组。

This is further enhanced by a radial splash of 8 concussive damage near the end of the flame that damages units that were not hit by both line splash attacks.

这种武器在其放射性的溅射远端能够造成最高8点震荡伤害，但是此时被攻击的单位不会同时被两条火焰击中。

As hydrogen atoms and catalyst atoms are normally found bound together as molecules or are bound in other compositions of matter, BlackLight has invented a solid fuel that uses conventional chemical reactions to generate the catalyst and atomic hydrogen at high reactant densities that in turn controllably achieves very high power densities.

通过分离出该进程中的能量产物，用外界元素中电解水。使用水作为燃料，不可见光发电机的可用成本是不昂贵的，而且，他不会带来空气污染或者放射性废物，还具有商业使用价值的氢成分作为氢产物。

Ca is widely abundant in nature and its rodioisotope 41 Ca is a cosmogenic nuclide with a half\|life of 10 5 years. However, the 41 Ca/ 40 Ca ratio in natural samples is very low and can only be measure d by accelerator mass spectrometry. The application of 41 Ca is ve ry i mportant not only in the life science but also in geological dating, global envi ronment change studies and astrophysics.

1 引言Ca在自然界中广泛存在，它不仅是人体中含量最丰富的元素之一[1] ，也是众多其他物质的组成部分。41Ca(半衰期为 1.0 3× 10 5a)属于Ca的放射性同位素中的一种，其衰变方式为轨道电子俘获，只发射3.3keV的X射线，天然样品中41Ca 40 Ca的值很小。

He/it discretionarily buries or transfers radioactive wastes sources

三、擅自掩埋或者转让放射性废物的

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
