片断

It is possible to preparing neutralizing MAb which target to active region of Stx2 by synthetical B cell epitope peptides. At present, the crystal structure of the compound of Stx2 and its ligand adenines has been resolved, and the active site of Stx2 is definite, which is the seventy-seventh amino acids, Ganimalon, of Stx2 A1 fragment.

Stx2通过B亚基与受体Gb3结合后，进入细胞，在弗林蛋白酶(一种钙敏感的丝氨酸蛋白酶)作用下A亚基被裂解为A1和A2两个片段，A1片断经内质网进入细胞质暴露毒性活性位点―A1片段发挥N-糖苷酶活性，导致真核细胞蛋白质合成的终止，最终导致细胞的死亡。

A typical area of habitat fragmentation in the Thousand-Island Lake, Zhejiang Province, was selected as subject to study effects of habitat variation as a result of island forming, on arbuscular mycorrhizae infection rate and its correlation with phosphatase activity in the rhizosphere of Castanopsis sclerophylla.

以浙江千岛湖典型生境片断化区域苦槠为材料，研究了水库形成后岛屿化导致的群落生境差异对苦槠AM侵染率的影响以及AM侵染率与根际土壤磷酸酶活性的相关性。

Here's a snippet from the roman numerals parser

Meanwhile, tree species in the upper canopy layer were more stable than that in the lower layers of the fragmented forest.

与连续森林比较，片断热带雨林的植物物种丰富度和物种多样性指数都比较低，而且有相当低比例的大高位芽、中高位芽和附生等生活型植物，而藤本、小高位芽和矮高位芽等生活型植物的比例则较高；泛热带、热带亚洲至热带非洲的区系成分比例较高，而当地成分则减少；群落的上层树木比下层树木更加稳定。

The lengths of the fragments within the bookends were found to vary according to the cultivar.

在这些书档里面DNA片断长度在不同的栽培变种之间不同。

The paper designs a flow of work, in which the user reads symbolic library XML document from distributed symbolic library, manages these symbols by visualization management tool, saves all classes of symbols XML document fragment and transforms into SLD document, realizes interactive mapping by dint of integrated application between OGC SLD and OGC WMS.

设计了由从分布式符号库读取符号库XML文档并以利用可视化管理工具进行符号的管理，存储为各种符号XML文档片断转换为SLD文档，通过OGC SLD与OGC WMS的综合应用于交互制图的工作流程。

Depending on how the polymer is manufactured, it may also contain some cyclic siloxane structures.

这一聚合物具有重复的(CH3)2SiO单元。这些材料是硅化学工业中的基本结构片断。

The primary purpose is for including material such as XML fragments, without needing to escape all the delimiters.

主要目的是为了在不转义所有的定界符的情况下包含诸如XML片断的材料。

There were also a number of comrades who were empiricists and who for a long period restricted themselves to their own fragmentary experience and did not understand the importance of theory for revolutionary practice or see the revolution as a whole, but worked blindly though industriously.

还有另一部分经验主义的同志长期拘守于自身的片断经验，不了解理论对于革命实践的重要性，看不见革命的全局，虽然也是辛苦地——但却是盲目地在工作。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
