Vg could be detected in haemolmph of the water—fed female at 48h after eclosion, too.

用10％的蜂蜜和清水分别饲喂两组成虫(简称"蜜组"和"水组")，以研究成虫期的营养对Vg发生和卵巢发育的影响，结果显示，成虫期营养对于Vg的启动合成并不起关键的决定性作用，两组成虫均可以在羽化的48小时检测到Vg，且水组中的血淋巴水平并不低于蜜组对照，但绝大多数水组个体的卵巢发育停留在卵黄沉积的某一时期，此时在血淋巴中也检测不到，只有约20％的饲水个体卵巢可以发育成熟，出少量卵；用高剂量的ZR515于羽化当日点滴处理饲水个体，可以使所有接受处理的饲水个体的卵巢发育成熟，但是产卵〓依旧低于对照组的，不能恢复正常；这说明成虫期营养对卵巢中全体卵母细胞的成熟是必需的，其作用的产生是通过内分泌系统途径实现的。

The results indicated that the inhibited concentrations of kanamycin of adventitious bud formation of Helianthus annus were 75 mg/L and 100 mg/L, when the carbenicillin was used in the transformation procedure; the concentrations was 300 mg/L when the growth of agrobacterium could be effectively inhibited. At the same time, the induction and growth of adventitious bud were not remarkably injured.

在以卡那霉素为抗性选择标记时，对油葵不定芽起完全抑制作用的Km临界浓度在75~100 mg/L；在以羧节青霉素为抑菌剂用于油葵遗传转化试验时，其浓度为300 mg/L时即可有效抑制农杆菌的生长，同时又不会对不定芽的诱导及生长产生明显的伤害作用。

Moreover, by discussing the role of geometrical proof in Ars Magna and Cardano's attitude on irrational number, negative number and imaginary number, the paper points out that the role of geometry in Renaissance algebra had been tending weaker.

同时，通过考察几何证明在《大术》中所起的作用以及卡尔达诺对无理数、负数和虚数的处理，指出在文艺复兴时几何在代数学中的作用己逐渐减弱。

And in the article, Limbaugh wrote that Sharpton played a leading role in two New York race riots back in the 90s.

在这篇文章中，Limbaugh写道，Sharpton在90年代两起纽约种族暴力中起着领导作用。

Result］ Under blood stasis, it can to some extent inhibit the production of primary cancer, the serum IL18 and HGF were reduced in mouse of liver metastasis with cancer, which may intervene the liver metastasis; Shensanqi extract had some definite function on the primary cancer of spleen and liver metastasis of rats with liver metastasis of cancer, the platelet exerted key functions in cancer hyperplasia, infiltration and metastasis.

结果］在血瘀状态下，可在一定程度上抑制原发肿瘤的生长，荷瘤肝转移小鼠血清IL18和HGF的水平降低，可能干预了肝转移的过程，参三七醇提液对荷瘤肝转移大鼠的脾脏原发肿瘤的生长和肝转移有一定抑制作用，血小板在肿瘤增殖、浸润和转移中起着重要作用。

In general, medium shot plays an important role in narrative, while long shot, full shot, close shot and close-up affect more the expression of characters' psychology and the audiences' aesthema.

在现代蒙太奇修辞中，中景一般在叙事上发挥着重要作用，而远景、全景、近景、特写往往在表现人物心理和影响观众观影心理上起着重要的作用，让皮埃尔热内导演的《天使爱美丽》(2001)中体现了这一观点。

Content abstract :Language and culture are having inalienable relation , language is acting as the intermediary effect in the process taking form in culture,; In the process of development of culture; Language is holding the post of the precis writer function; Language is playing carrier's role in the process of the culture delivery but.

内容摘要：语言和文化有着不可分割的关系，在文化形成过程中，语言充当着媒介作用；在文化的发展过程中；语言又担任着记录功能；而在文化的传递过程中，语言又起着载体的作用。

Under the Dred Scott decision "squatter sovereignty" squatted out of existence, tumbled down like temporary scaffolding,--like the mould at the foundry, served through one blast and fell back into loose sand,--helped to carry an election, and then was kicked to the winds.

在德莱德。斯科特裁决中，"人民主权"土崩瓦解，像临时搭起的脚手架一般散了身骨──像铸铁厂翻砂模具，浇铸过一次后就复为一盘散沙──它在一次选举中起了点作用，然后就弃为废物，随风而去了。

The threshold of lithium tantalite under single-shot is found to be 1.84J /cm 2 and the avalanche rate was determined to be 1.01 cm 2 /J by calculation. We found that avalanche dominates the ablation process, while photoionization serves as a free electron provider.

在800nm飞秒激光脉冲作用下，钽酸锂晶体单脉冲烧蚀阈值为1.84 J /cm 2；在此基础上，我们通过建立钽酸锂晶体中导带电子密度演化微分方程，并数值求解，得到了钽酸锂的碰撞电离速率系数为1.01 cm 2 /J ，并得出在钽酸锂表面烧蚀中，光致电离提供种子电子，雪崩电离起主导作用的结论。

Ray plays flamboyant parts in amateur theatricals. He also plays the "mommy" role at home by doing most of the worrying, he says.

而Ray则在业余戏剧方面对Ethan起着重要的作用，同时他说他也在家当起了妈妈，做"她"应该做的事情。
