Some approved aneugens Trip terygiuwlIypogaucum (evelHutch, colchicine, thiabendazole, a tropine sulfate,d-ubocurarine was added into the reactive system respectively and the changes of their absorption values were taken down during different periods under the conditions of 37 0C and 350nm .

本研究通过多步聚合和解聚合反应从猪脑中分离纯化微管蛋白，建立微管蛋白的体外聚合和解聚合反应平衡体系，并将已证实的非整倍体诱发剂（昆明山海棠根部水抽提物、2-（4′-噻唑）苯丙咪唑、硫酸阿托品、d-筒箭毒碱）分别加入此反应平衡体系中，于37℃、350nm条件下，记录此体系不同时期的吸光值变化，与阳性对照物和溶剂对照处理平衡体系后的吸光值在相同时间点作比较，以此评估这几类非整倍体诱发剂对离体条件下的微管蛋白聚合的影响，寻求这几类非整倍体诱发剂是否可通过抑制微管蛋白聚合作用途径而诱发非整倍体。

Long and narrow in the form of a sharp cone truncated at its base.

Total RNA samples used in Northern blotting were extracted from the light-exposed and light-interrupted cortex tissue of tuberous root of the two turnip cultivars.

Northern分析采用的RNA样品，是从上述两品种的光处理和暗处理的肉质根部周皮层中提取的总RNA。

When the plantlet with induced roots were shifted to tuberous root inducing culture medium, the root obviously augmented which consequently led to the formation of test tube tuberous root. The optimized medium was MS+6-BA2mg/L+NAA 0.1 mg/L+sucrose 5%.

已生根的试管苗转入块根诱导培养基中，根部明显增粗，形成粉葛的试管块根，最佳培养基配方为：MS+6-BA 2mg/L+NAA 0.1mg/L+蔗糖5%。

Over 90 percent of the accumulation of hybrid tulip tree uptake to Pb and Cd was in root, and the following distribution was in stem and leaf.

杂交鹅掌楸对Pb、Cd的吸收积累量90%以上集中在根部，其次为茎和叶。

在下面，坑里植物根部的深处，Edric可怜巴巴地声音穿了上来请求帮助，辩称他的腿在掉下来时骨折了。

A scattered existence of parts would undercut the universalist theory.

这样的'部分的分散存在'会从根部破坏共相论者的理论。

Only think, if you have been pulling a vegetative root, so the plant finally will be damaged.

想想看，如果你一直拉植物的根部，那么植物最终将被损坏。

Objective To explore the feasibility and application of laparoscopic appendectomy by silk suture with three trocars.Methods The root of vermiform appendix was stitched up and enwrapped in laparoscopic appendectomy by silk stitches.

目的 探讨三孔缝合打结法在腹腔镜阑尾切除术中的可行性及应用方法在腹腔镜阑尾切除术中，应用三孔丝线缝合及结扎的方法处理阑尾根部、包埋阑尾残端。

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。
