The anti-ischemia effect in myocardium of corydalis rhizoma is related to the direct protective effects on cardiomyocytes of its components, tetrahydropalmatine, dehydrocorydaline, berberine and palmatine, amomg which tetrahydropalmatine and dehydrocorydaline are the most important, the former with high safety and low efficacy, while the latter with low safety and high efficacy. And the direct protective effects on cardiomyocytes of these four components, may be attained through mechanisms other than anti-peroxidation.

延胡索抗心肌缺血损伤的作用与其成分延胡索乙素、脱氢紫堇碱、黄连素和巴马汀对心肌细胞的直接保护能力有关；其中，延胡索乙素和脱氢紫堇碱的作用最为重要，前者安全性高，但效能较低，后者安全性低，而效能较高；而这4个单体的保护作用可能是通过抗氧化损伤之外的机制达到的。

Research results of C atomicity in paraffin hydrocarbons show the linear paraffin hydrocarbons （from Tetradecane to Heptadecane） are almost burned up at lower loads, and some components of the SOF are not directly from fuel, but from lubricant oil or middle polymerization products of fuel.

SOF烷烃碳原子数分布的研究表明，低负荷工况下，燃油中易燃的正十四烷～正十七烷的绝大部分被烧掉，SOF中有些成分不是直接来自燃油，而是来自润滑油或燃油聚合反应的中间产物：高负荷工况下，供油量较多导致一部分正十四烷～正十七烷来不及燃烧就排出机外，SOF中还有些成分则是燃油高温裂解的产物。

The structures and composition of the precipitates at PHT powder surface and at PPB of hipped materials are investigated. The formation of PPB precipitation is directly related to the surface conditions of as-atomized powder. Precipitates at PPB are mainly MC carbides and ZrO〓.

预处理粉末表面及压坯原始颗粒边界的表面成分及析出相分析表明，原始颗粒边界析出的形成是与雾化粉末表面状况直接相关的，表面或界面析出相主要是MC型的碳化物和ZrO〓。

Recent study proved that the thickness, microstructure, chemistry composition of oxide film can affected the biological corrosion-resistance ability, hydrophile property and bioactive macro molecule absorption, then affected the biocompatibility and the match process in the body.

目前的研究认为钛表面氧化膜的厚度、微观结构、化学成分及TiO_2的结构类型等，与材料的耐腐蚀性、表面亲水性和生物大分子的选择性吸附有着直接的关系，进而影响到钛的生物相容性以及在体内的愈合过程。

The comparative studies of lithogeochemistry for the volcano-intrusive complexes both from Jiulongzhang and from xiangshan reveal that the chemical compositions of the volcano intrusive complexes in the two areas are very close, and the trace element spidergrams and REE patterns basically coincide with each other. It is also shown that the two volcano-intrusive complexes have the same source features and the active continental margin tectonic settings. At the same time, it is found that, from early volcanic magma activities to later intrusive magma activities, the content of SiO2 and the Rb/Sr ratio decreased, on the contrary, the content of MgO and the ratios of K/Rb, Ba/Rb and LREE/HREE increased. It is shown that the hypabyssal or ultra-hypabyssal intrusives are not the products of the volcanic magmatic differentiation.

两地区的火山－侵入杂岩的岩石化学成分及其变化特点极为相近，微量元素蛛网图和稀土配分型式也基本一致，它们具有相似的岩浆过程和统一的活动陆缘构造背景；同时，从早期火山岩浆活动到晚期浅成－超浅成岩浆侵入活动，其w(SiO2)和w/w的值降低，而w以及w/w、w/w和w/w的值增高，晚期浅成－超浅成侵入岩与早期火山岩没有直接的分异演化关系。
