In addition, comparing with moving mirror system the rotating mirror system is of benefit to increase the mainipulating speed of an optical trap, simp lify the mechanism of an optical tweezers, reduce its cost, and shorten the cycle of completing an optical tweezers.

此外，比较分析表明，与平移反射镜系统相比，转镜系统在光镊技术中的应用可加快光镊操纵速度、简化光阱位置操纵系统的复杂程度、有利于系统开发成本的减少及开发周期的缩短。

Previous studies have demonstrated that primary spermatocyte can undergo meiotic divisions in MI oocytes and the resulting embryos can develop to term. However, the success rate is very poor.

已经证明初级精母细胞在显微融入MI卵母细胞后可以完成减数分裂并且产生的胚胎可以发育到期，只是发育率还非常低，作为一种形式的核移植，细胞周期的同步化处理对于胚胎的发育具有重要意义。

Perhaps even more importantly, they also found that the flow was faster at sunspot cycle minimum than at maximum and substantially faster on the approach to the current minimum than it was at the last solar minimum.

也许更重要的是，他们还发现，流量速度远远快于在最大太阳黑子周期的最低，大大快于目前最低的方法比在最后太阳最低的。

The centrepiece is a teocalli, a massive votive sculpture in the shape of a temple platform, built in 1507 to mark the end of a 52-year cycle in the Mexica calendar.

整个展览的中心是一座古代大型祭祀神庙的雕刻，雕刻成神殿平台之形。这座建于1507年的神庙用来标示古墨西哥历法中52年周期的结束。

The results also show the different persistence of Chinese business cycle in three regimes through transition probability.

我国经济周期的持续性主要体现在各个增长阶段的自维持概率和阶段性之间的转移概率的不同。

Moreover, the results show the asymmetry of Chinese business cycles in three regimes through different mean, variance and transition probability.

我国经济周期的非对称性主要体现在各个增长阶段的均值、方差、阶段性之间的转移概率的不同。

Although this technique has been widely used with cultured cells from model organisms and with many unicellular organisms, it remains challenging to apply this technique to non-conventional organisms that undergo complex life cycles.

尽管这个技术已经被广泛应用到模式动物的培养细胞和很多单细胞生物，应用这个技术到经历复杂生命周期的不常见的生物上仍然是挑战性的。

We found that ZZaPK counteracted ZAK function in cell counting assay, and restored ZAK-mediated cell cycle arrest in H460 cells.

在细胞试验的结果中可得知ZZaPK回复了ZAK所造成的细胞抑制作用，而在细胞周期的调控上也表现出类似H460正常肺癌细胞的反应。

The Interference of cell cycle and proliferation of BGC-803 and Hela cell by water extraction of Agrimonia is studied by electronic microscopy and flowcytometry respectively, and the IL-12 and TGF-β are also detected by ELISA in order to explore the pharmacological mechanism of Agrimonia.

仙鹤草抗肿瘤研究应用流式细胞技术和电镜技术，在体外分别研究了仙鹤草水提取液对胃癌BGC-803和宫痉癌Hela细胞的生长抑制作用和细胞周期的影响，同时检测对免疫活性因子TGF-β和IL-12表达的影响，阐明其对人癌细胞生长抑制的药理机制。

Papers dealing with the life stages of anadromous and catadromous species in estuaries and inshore coastal zones, theoretical papers, research papers, short communications and review articles, the proceedings of conferences and symposia are also published.

同时也刊载有关江口和沿海地区溯河产卵和为产卵顺流而下的鱼类的生命周期的论文，理论性论文，研究性文章，短通讯和评论性文章，以及会议与座谈会的会议记录。

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。
