毒素

This insidious mechanism, which does not deter the herbivore from feeding but impairs its recruitment, will restrain the cohort size of the next generation of early-rising overwinterers. Such a transgenerational plant–herbivore interaction could explain the recurringly inefficient use of a predictable, potentially valuable food resource—the spring diatom bloom—by marine zooplankton.

但是现在，用桡脚类动物Calanus helgolandicus所做的饲养实验表明，在硅藻与其捕食者之间在进行一场化学战：当被咬碎时，一些早期繁茂的硅藻会释放毒素，杀死以硅藻为食的桡脚类的后代；这样虽然不能阻止桡脚类继续吃硅藻，但却能影响其&兵员补充&，限制来年较早复苏的过冬者的数量。

Both Sclerotinia resistance and oxalic acid tolerance were significantly increased in senescence leaves of T1 lines.

转基因植株叶片尤其是衰老叶片对核盘菌的抗性及对草酸毒素的耐性均得到了增强。

The scourging is supposed to improve the flow of blood, driving out toxins and curing all manner of ills, including hangovers.

自我折磨的目标旨在改善血液循环，排除体内毒素，治疗各种毛病，包括宿醉。

In this part of study, we have further investigated the effect H2S on endotoxic shock through observation of H2S concentration in main organs. 154 male Wistar rats were seldomly divided into 4 groups: 1. control group (n=28): animalswere injected with saline (1 ml/kg).

本实验通过观察大鼠主要器官组织中H2S含量的变化及其与内毒素休克组织损伤的关系，进一步探讨H2S在内毒素休克的病理生理调节机制中的作用。

Function mechanism of Bt to Helicoverpa armigera and Mythimna separata is studied in this thesis. The results are as follows:1 Bt CrylAc toxin has high toxicity to H. armigera, but has low toxicity to M. separata.

本论文是以棉铃虫和粘虫为实验试虫，研究苏云金芽孢杆菌Bt CrylAcE毒素对昆虫的作用机理，为更好的了解Bt的作用机理以及了解昆虫的抗性问题奠定理论基础。

Separata is higher than H. armigera. 130kD Bt pro-toxin is decomposed by mid-gut juice in 37℃ and 30min and 60 min , 60kD toxin can be got by H.

Bt CrylAcE毒素为许多分子量约为60kD的毒性肽组成，且各组分均具有生物活性，而非某一种组分单独起毒杀昆虫的作用。

Separata was significant under the concentration of over 1.00 mgmL^(-1), and showed dosage-dependant pattern. The highest antifeedant rate was 65.68 %. Which concentration is within 0.25~1.00 mgmL^(-1), the feed intake of the 4th instar larvae of M.

浓度大于1.00mgmL^(-1)的羟基马桑毒素对3龄粘虫幼虫有明显的拒食作用，且随着药剂浓度的增大，拒食作用增强，最大拒食率达65.68环。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
