Two patent publi cations are of particular relevance here: Chinese patent publication No CN1096031 A claims the use of the spirostane sapogenin, sarsasapogenin, in the treatment of SDAT.

已经相关有专利应用指南说明大量的皂甙配基醇可以用于治疗包括SDAT 的功能，而该类皂甙配基醇，下面介绍两个专利出版物：中国的No CN1096031A宣布治疗SDAT中使用菝葜配基，其中的提示很简单。

By disrupting the impermeability of the sarcolemma, extracellular cations and fluid flow down the electrochemical gradient into sarcoplasm, overwhelming the capacity of the cationic extrusion pumps14–18 and leading to swelling of the myocytes.

肌纤维膜的不渗透性被破坏，细胞外阳离子与液体向肌浆流入，超过阳离子的泵出能力，导致肌细胞水肿。

Contaminant cations such as calcium,magnesium,barium,strontium,and radium and anions such as fluoride ,nitrate,fulvates,humates,arsenate,selenate,chromate ,and anioic complexs of uranium can be removed from water by using ion exchange or adsoption onto activiated alumina.

具有污染能力的像Ca，Mg，Ba，Sr，Ra的阳离子，和像氟化物，硝化物，黄酸物，腐质酸物，砷酸盐，硒酸盐和铬酸盐的负离子以及像铀一样的负离子复合物可以通过离子交换和离子吸附从水中排除。

This case has two impli cations: first, comparing to" Economic Man" hypothesis in the Western," Self-profit" theory has inner shortage. Second, for establishing modern market economy, it is only an essential condition to acknowledge to human' s self-profit inherent quality. Other important elements, such as consciousness of liberty, democracy, modern law institution, are full conditions of market economy' s development.

较之于西方的"经济人"假设，先秦时期的"自利人"描述在理论内涵上是有缺陷的；承认人都具有求利的本性是建立市场经济的必要条件，只有具备了其他现代意识和社会机制，市场经济体制才能建立和发展起来。

The positive side is that cations make gel particles smaller and the cation bridge linkage between gel particles is formed. So the strength of sodium silicate is 10～12 times higher than that of silicic acid.

好的影响是它能使胶粒细化，胶粒间存在阳离子桥连接，使前者的机械强度比后者大10～12倍。

The results showed that the amounts of base cations leached from calcareous soils and coastal solonchak were lower than the cation exchange capacity and the releasing amounts of Al3+ being lower than 0.40mmol·kg-1 all the way under the treatment of simulated acid rain with each pH value from 2.5 to 5.6,so the H+ buffering...

结果表明，石灰土和滨海盐土的阳离子淋溶量低于阳离子交换量，土壤主要处于阳离子交换缓冲范围和碳酸盐-硅酸盐缓冲范围，Al释放量一般低于0.40mmol·kg~(-1)，铁铝土纲系列土壤在阳离子释放总量超过阳离子交换量后，淋溶液pH值急剧下降，此时Al淋溶量明显增加，质子缓冲转向Al缓冲范围，其释放量决定于土壤富铁铝化程度的高低和活性Al含量的多少，紫色土在低pH模拟酸雨淋溶下，由于含大量硅铝率较高的易风化原生或次生矿物，盐基释放量高于CEC，但Al释放量未明显增加，淋溶液pH也较稳定，土壤尚处于矿物风化为主的硅酸盐缓冲范围。

I'm strongly against the death penalty — it's an eye for an eye.

我不赞成死刑——这是以牙还牙的报复行为。

And to get you the support you need, we're enlisting all elements of our national power: our diplomacy and development, our economic might and our moral suasion, so that you and the rest of our military do not bear the burden of our security alone.
