The mechanical testing indicates that alloying and solid-solution treatment can evidently enhance mechanical properties of ZM5 alloy,Ca and mischmetal additions refined the microstructure obviously.

拉伸试验表明，合金元素的加入和固溶处理明显改善了ZM5镁合金的常温力学性能，微量Ca和稀土元素的加入能够显著细化显微组织。

Intense aggregation of precipitated particles containing Ca〓 could be seen within the small vacuoles, but not in the cytoplasm at the early stage.

早期阶段的珠心细胞中，Ca〓沉淀的聚集主要是在小液泡而不是细胞质中。

Compared with the original powder, the content of Si in the three troches increased by 8.09, 14.68, 12.64 times respectively. Accordingly, they were added with a little amount of silica gel. The content of trace element such as Ca, Fe, Zn in sample 4 have optimized clearly.

结果表明：3种片剂中均添加了部分晶体乳糖；根据3种片剂中Si含量比原粉的Si平均值分别增加了8.09、14.68、12.64倍的差异，可知片剂中均添加了微量的硅胶；样品4中微量元素Ca、Fe、Zn的含量明显优化。

Scripps Institute of the United States and his马克耶格尔Professor University of Virginia, the University of Utah colleagues used X-ray crystal photography, the first detailed description of the composition of the HIV virus capsid protein precursors of the hexagonal molecular structure of high-definition, they said hexagonal protein precursors such as CA VI protein oligomers.

美国斯克里普斯研究所的马克。耶格尔教授和他在弗吉尼亚大学、犹他大学的同事一起，采用X光晶体照相术，第一次详细描述了构成HIV病毒衣壳的六边形蛋白体的高清分子结构，他们称这种六边形蛋白体为CA蛋白六聚物。

All the molecular complexes, obtained by the interaction between several low-lying tautomers of RNA nucleic acid and Ca^＋ on the different binding sites, were considered.

通过考虑Ca^＋作用于RNA碱基互变异构体的不同位置，获得了所有稳定的复合物。

The results shawed that DBH was positively correlated with nutrient contents of N, P, K, Ca, Fe, Cu and Zn, while negatively correlated with foliar N:P ratio.

通过对所得数据进行相关分析得出，胸径和树高均与叶片的N、P、K、Ca、Fe、Cu和Zn含量呈正相关，与叶片N：P比值呈负相关。

The biomass production of grafted seedlings, activities of antioxidant enzymes and contents of proline and soluble protein in leaves of grafted seedlings were significantly higher than those of own-root seedlings, while O2(superscript -) production rate, contents of H2O2 and MDA in leaves of grafted seedlings were significantly lower than those of own-root seedlings under Ca(NO3)2 stress.

结果表明，Ca(NO3)2胁迫明显抑制植株生长，显著提高植株抗氧化酶活性，显著增加植株O2生成速率以及H2O2、MDA、脯氨酸和可溶性蛋白含量，但胁迫后嫁接苗的生物量显著高于自根苗，抗氧化酶活性、脯氨酸和可溶性蛋白含量均显著高于自根苗，而O2生成速率、H2O2和MDA含量则显著低于自根苗。

Using resealed erythrocyte membranes, we further show that lipid scrambling is inducible by raising the intracellular [Ca(2+)] and that K ions have a direct inhibitory effect on this process.

我们采用重新包封的红细胞膜进一步证实，脂质紊乱由细胞内增加的[Ca(2+)]所诱发，而K离子对此过程则具有直接抑制作用。

Lipid scrambling in resealed ghosts occurs in the absence of cell shrinkage and microvesicle formation, processes that are generally attributed to Ca(2+)-induced lipid scrambling in intact erythrocytes.

重封血影细胞中的脂质紊乱在细胞皱缩缺失和微泡形成时发生，此过程在完整的红细胞中通常归因于Ca(2+)诱导的脂质紊乱。

Once this time expires, the CA certificate will have to be recreated, and all of its certificates regranted.

这个是CA证书有效的天数，一旦这个时间过期，证书将必须重新创建，并且它之下的所有证书要重新获得许可

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
