Some investigations suggested that cyclins and CDK played an important role in the regulation of endomitosis of megakaryocyte. However, the mechanism of cyclins and CDK in the regulation of endomitosis of fetal megakaryocytes during ontogenesis and the relationship between cyclins/CDK and retardation of endomitosis of fetal mgakaryocyte is totally unknown.

一些研究发现周期蛋白和CDK在巨核细胞核内有丝分裂的调控上起重要作用，然而，周期蛋白和 CDK在胎儿巨核细胞核内有丝分裂调控上所起的作用，及其与胎儿巨核细胞核内复制延迟的关系目前全然不知。

Products of this enzyme have important functions in plant growth and development, as well as in response to environmental stress.

因为该酶作用的产物在植物的生长发育过程中以及在植物对环境胁迫反应中起着重要的作用，因此一直是人们研究的热点。

With the rapid development of diagnostic audiology, there comes more and more audiometries. Though advanced electrophysiology audiometry takes a prominence place in clinical and rehabilitation audiology, behavioral audiometry has its unique advantage, which electrophysiology audiometry cannot supercede. Thus, behavioral audiometry runs through the process of the recovery of deaf children, not only in the diagnose of pediatric auditory loss, also in the hearing-aid threshold obtaining and the adjustment of artificial cochlea.

目的 行为测听技术有其独特的优势，有着电生理测听技术不可替代的作用，在临床听力学特别是聋儿康复过程中贯穿始终，不但用于小儿听力损失的诊断，在小儿助听听阈获得及人工耳蜗调试中起着重要作用。

In the tissues of mature fishes, hira mRNA can be detected in ovary and brain. Based on the expression characterization, it may play a definitive role in maintaining the function of ovary and brain.

成鱼组织中，Caghira在卵巢和脑中均有表达，但脑中表达量较弱，说明该基因在维持卵巢和脑组织作用中起一定作用。

In general, the function of ERαis mainly in the process of hyperplasia and histogeny of cell and tissue.

一般来讲ERα主要在组织细胞的增殖和分化过程中起主要作用，而ERβ在卵泡、骨骼发育和抑制细胞增殖方面发挥作用。

This paper compared them at the cultural levels and concluded that they emerged in two different cultures. The development of CBA is following the traditional cultural values and is limiting the distribution of the new profits in an intangible and invisible way.

对比了两种不同篮球文化的层面差异，得出结论：CBA与NBA在两种不同文化氛围中诞生、成长，文化力对两者的作用方式不同；文化力对主体起着潜移默化的作用，CBA的发展还在有意或无意地遵循着传统文化价值模式，而且以一种看不见、摸不着的形式阻碍新的利益分配方式的产生。

Calculations indicate that Ni-Ni interaction in Ni81B19 alloy is stronger than metallic bond in pure Ni. However, the Ni-Ni interaction in pure Ni is stronger than that in Ni80P20 alloy. Direct B-B contact in Ni81B19 alloys appears in our simulation, however no direct P-P contact in Ni80P20 alloys is found.
