胚胎

Caghira gene is expressed in the unfertilized eggs and all stages of embryogenesis and the quantity of Caghira gene expression didn\'t changeobviously, which could be inferred that hira gene had an effect on gynogenetic development of gibel carp.

在银鲫的未受精卵中和胚胎发育不同阶段均可以检测到少量的转录产物，表达量未检测到明显变化，表明hira基因可能在银鲫雌核发育过程中发挥一定作用。

Meanwhile, when using the deletion as a DNA marker, the result suggested that Cy homozygote be lethal in embryo period.

同时以该缺失作为Cy染色体的DNA标记，通过基因型多态分析，初步证实Cy纯合型可导致果蝇胚胎期死亡。

The concept of cell differentiation; tissue-specific genes; and house-keeping gene; combinational control arouse expression of tissue-specific gene; the factors which have influence on cell differentiation; totipotency; cell differentiation and embryo development.

Archimedes' this experiment is the embryo of "hydrostatics".

阿基米德的这个实验，就是"静水力学"的胚胎。

The classic example is the ear ossicles of mammals, which we know from palaeontological and embryological studies originated in the upper and lower jaws and the hyoid of their Synapsid ancestors, and further back still were part of the gill arches of early fish.

典型的例子是哺乳动物的听小骨。我们从古生物学和胚胎学研究了解到，哺乳动物的听小骨起源于它们单弓型祖先的上下颌骨和舌骨，再往前则是早期鱼的鳃弓的一部分。

Many studies of phosphorus,glucose,hypoxanthine and cytoplasmic factors on early embryo developmental block carried out by different methods such as morphology,biochemistry,molecular biology and micromanipulation have been reviewed.

对此，人们用形态学、生物化学、分子生物学、显微操作等手段开展了磷酸、葡萄糖、次黄嘌呤和细胞质因素对早期胚胎发育阻滞的影响的研究。

To obtain fetal lung tissue, the fetuses were removed by hysterotomy after lethal injection of pentobarbital sodium to the dam.

要获得胚胎肺组织，胎儿被删除子宫切开术后注射致死戊巴比妥钠以大坝。

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。
