The effect ofα-methyl-D-mannoside and bivalence metal ion on LCA coupling to epoxy-coated magnetic particles is not significant.

研究α-甲基甘露糖及二价金属离子对其分离纯化糖蛋白的影响，二者对于凝集素与环氧磁粒的偶联并无显著影响。

We also study the effect ofα-methyl-D-mannoside and bivalence metal ion on LCA coupling to epoxy-coated magnetic particles.

研究α-甲基甘露糖苷及二价金属离子对于偶联反应的影响。

Although bivalency may play a role, others have observed a plateau in drug uptake with the Fab′ fragments of the human chimerized version of the antibody, albeit over a more limited range of ligand numbers.

虽然抗体的二价性可能可能在此发挥作用，但其它人还观察到在使用人嵌合抗体的Fab′片段时，纵然配体数大大超出了限界，仍然能明显提高细胞对药物的摄取。

Rod Curtis at the World Health Organization in Geneva says the new bivalent vaccine solves this problem.

在日内瓦的世界卫生组织成员Rod Curtis表示，新的二价疫苗能够解决这个问题。

Under the instruction of above-mentioned theoretical results, in the thesis chapter 10, the strongly electron-withdrawing anion, C_5O_5~(2-)[dianion of croconic acid (4,5-dihydroxycyclopent-4- ene-1,2,3-trione)], was chosen as the chelator to coordinate with boron to form lithium salt, which will yield high ionic conductivity solutions, and exhibit wide electrochemical stability windows and high thermal stability. As described in the chapter, two new lithium salts containing C_5O_5~(2-), lithium bisborate and its novel derivative, lithium borate for Li-ion battery electrolytes were synthesized.

在上述理论结果的指导下，论文第十章选择了克酮酸二价阴离子——具有很强的酸性、较好的芳香性、较大的电荷分散性、形成的配合阴离子具有较显著的共轭性——作为配体与B配位，合成了二种新的锂盐，通过实验测定了它们的结构和在有机溶剂中的溶解性。

In particular, the documentation of rapid and extensive non-Mendelian genetic and epigenetic changes that often accompany nascent polyploidy is revealing: the resulting non-additive and novel gene expression at global, regional and local levels, and timely restoration of meiotic chromosomal behavior towards bivalent pairing and disomic inheritance may ensure rapid establishment and stabilization as well as its long-term evolutionary success.

特别是，所发现的在多倍体形成初期，快速且大量产生的非孟德尔遗传变异和表观遗传变异为相关机理的探讨提供了重要的启示。不同尺度上的基因非加性表达以及染色体二价体联会和二体遗传方式的快速建立可能对新形成多倍体的早期稳定和长期进化优势都具有重要意义。

There was no abnormal behavior observed in meiotic chromosomes in carrot. It has simultaneous cytokinesis. There are nine bivalents (9II) at metaphase I, indicating it is a typical diploid species.

通过观察胡萝卜花粉母细胞的减数分裂过程，发现其行为正常，是同时型胞质分裂，中期Ⅰ有9个二价体(9Ⅱ)，为典型的二倍体物种。

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。
