IGF2, which encodes a protein functioning as a fetal growth factor and a cell mitogen, is expressed only from paternally allele in most tissues but from both alleles in adult liver. H1 9, which acts as an RNA, is a gene of unknown function and expressed only from maternally allele.

IGF2编码的胰岛素样生长因子-2是一种胚胎生长因子及细胞有丝分裂原，在人体内大多数组织中特异地表达父系来源的等位基因，而母源等位基因处于印记状态。H19表达一种功能尚不清楚的RNA，其印记状态与IGF2相反，目前发现H19在正常组织内均为母源等位基因表达，父源等位基因印记。

The effect of two plant growth regulaors on the growth, chlorophyll content and dry weight of Pavlova viridis was studied.

研究了二种植物生长调节剂对绿色巴夫藻的生长、叶绿素含量和干重的影响。

Experiments were conducted to measure the impact of biofouling on the growth and reproduction of pearl oyster Pinctada martensii.

主要研究定期清除污损生物的合浦珠母贝与不清除污损生物的合浦珠母贝在生长及繁殖上的差异，用以说明污损生物对合浦珠母贝的生长及繁殖的影响。

And at 600℃,in addition to needle carbide,there was pearlite.

在500℃时效处理时，沿晶界形核并向晶内生长的针状碳化物与母相奥氏体之间的位向关系和在晶内析出的针状碳化物的不同；以及在晶内析出的针状碳化物可以交叉生长。

It was shown that glucose utilization affected the primary carbon metabolic flux of cells. The oxidative branch of pentose phosphate pathway was apparently more active during mixotrophic growth than that during photoautotrophic growth.

结果表明，葡萄糖的利用影响了细胞初级碳代谢的流动状况，混合营养生长过程比光自养生长过程磷酸戊糖途径氧化性分支的反应程度明显加强。

Possitive staining of Gas7 was mainly located on the membrane and perikaryon cytoplasm of Purkinje cells.

生长休止基因家族[1]是与细胞分化和活化相关的重要调节子，生长休止特定蛋白7(Gas7)属于其中一种。

Preliminary studies indicate that under conditions of rather perfect crystal boundaries and periodic reversal of the direction in rotation, capping would be more effective if the solution bas a higher degree of supersaturation.

另一方面比较详细地研究了晶体在培养器中的取向对ADP晶面生长速率和晶体生长习性的影响，初步确定了维持晶体匀称生长较好的空间取向。

Mao Ling Duan said that although the human body can be from day-to-day diet to fluoride intake, and intake hard enough, the development of early childhood tooth growth will be affected, so early childhood development in the permanent tooth germ plus if the participation of fluoride Heng Calcified teeth, the permanent teeth grow in the future will be more acid-resistant.

段茂玲表示，人体虽可自日常饮食中摄取到氟，却难足量摄取，对发育中的幼儿牙齿生长会有影响，所以，幼儿发育中的恒牙牙胚若有外加的氟化物参与恒牙钙化，未来生长出来的恒牙会更耐酸。

The results indicate that the average diameter of ZnO nanorod is about 21 nm, and the size distribution is about 18～25 nm. The nanorods, growing along [001] direction, are perpendicularly oriented to the substrate.

测试结果表明， ZnO纳米棒阵列的平均直径为21 nm，粒径分布窄，约18～25 nm，择优生长取向为[001]方向，垂直于基底生长。

The lag growth phase, as well as the stationary phase was delayed with the increase of salinity.

随着盐度的增加，三株菌株生长的延迟期增加，到达生长稳定期的时间也相应增加。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
