The long-term opening of mitochondria permeability transition pore results in the release of cytochrome C, apoptosis inducing factors, Ca2+ and other apoptosis factors into cytoplasm, which can destruct the whole cell structure and function by activating the main member of apoptosis protein family——caspase, or destroying the intranuclear chromoplasm independently, or affecting other protein relying on Ca2+, and finally lead to the formation of apoptotic body.

线粒体是真核生物能量和代谢的中心，也是细胞凋亡信号传导途径中起关键作用的细胞器，越来越多的研究表明，在凋亡信号的刺激下，线粒体发生膨胀，其外膜膜电位降低，外膜破裂后释放出膜间隙的诸多凋亡效应因子，在细胞凋亡中起着主开关的作用。

In the structure of crime-liability-punishment, personal dangerousness doesn't matter necessarily, rather, it only acts as a modifier to certain degrees.

人身危险性在罪责刑结构中，并不当然地起决定作用，只是在一定程度上起着修正的作用。

It is the fluorosilicic ion that exsits in the slurry and plays an important role in flotation, fluorosilicic ion not only reacted with Fe〓 on the surface of aegirine to form ionic compound, but also formed stable Si-F bond in Si-O etching reaction. Only ionic compound was obtained when it was attached to hematite surface according to the theories of coordination chemistry, Compared with SiF〓, Fatty acid ion preferentially acts with Fe〓 on the minerals surface, therefore, SiF〓 Can't obstruct the adsorption of collector on the surface of hematite completly, but can reduce the flotation recovery of aegirine selectively.

运用FTIR、XPS等测试方法仔细研究了氟硅酸盐抑制剂对含铁硅酸盐钠辉石的选择性抑制作用机理，氟硅酸盐在弱酸性条件下对赤铁矿浮选的抑制作用很微弱，而对含铁硅酸盐钠辉石强烈抑制，从而扩大了两者之间的浮选差异；SiF〓是矿浆中起抑制作用的主要成分，SiF〓不仅与钠辉石表面的Fe〓形成离子型配合物，而且还与Si-O键形成稳定的Si-F共价键，而与赤铁矿表面只能形成离子型配合物，根据晶体配位场理论，与SiF〓相比较羧酸根离子将优先与矿物表面Fe〓发生配位作用，因此SiF〓的存在并不能完全阻碍捕收剂在赤铁矿表面的吸附作用，却能够选择性地抑制钠辉石的上浮。

越来越多的试验表明，根分泌物在根与根、根与根际微生物间起着重要作用，并以其为媒介在植物与环境的相互作用中起着传递信息的作用。

In this article, the author analyzes metaphor and metonymy comparatively and points out their respective roles in the semantic extension of a word: Metaphorical thinking and metonymical thinking are two important processes leading to semantic extension, but metaphorical thinking is more important in this respect.

本文通过对比研究，指出隐喻和转喻在词义延伸中所起的作用：隐喻和转喻思维使词义延伸成为可能，而隐喻思维在词义延伸中所起的作用更大。

PEM and crura may have a role in anti-reflux mechanism, and it decreases as the child grows.

After doing a lot of experiments, the paper analyses the parameters that take effects when people judge directions between two objects, and concludes that there are two factors that play important roles: one is the diameter of the convex hull of the point set of two objects; another is the visible field between two objects.

在大量实验的基础上得出结论：在两目标方向关系判断中，目标图形的各个部分所起的作用是不一样的，起主要作用的因素有两个，其一是两目标间的可视区域，其二是两目标群点凸壳的直径。

Besides, it has the advantage of lower cost, fewer breakdowns and continuous transportation.

It is suggested that CDK2 might progress the proliferation of endothelial cells in human proliferative hernangiomas; while p27(superscript Kip1) might inhibit the proliferation of endothelial cells in involuting hemangiomas.

p27(上标 kip1)能抑制血管瘤内皮细胞的增殖，在血管瘤的退化过程中起了重要作用；而CDK2能促进血管瘤内皮细胞增殖，在血管瘤的增生过程中起了重要作用。
