查询词典 total cleavage

This paper reviews pathways of aerobic and anaerobic microbiological degradation of PCP. It can be concluded that reductively dechlorination prior to ring cleavage plays a key role in mineralization of PCP.

文章通过综述好氧与厌氧微生物降解五氯酚的降解菌和降解途径，认为五氯酚首先通过脱氯转化为低氯代化合物后再开环，因此脱氯就成为五氯酚降解的关键步骤。

In this manner, the replicative senescence is avoided due to the rapid cleavage rate of the cell line.

其中，H1299缺少了老化常有过度表现的p53基因，在此也可探讨p53基因的有无，是否对细胞的老化造成影响。

A petrographic analysis combined with electron microprobe analysis and SEM shows that black opaque matters, whose composition is mostly of microcrystalline silicate and magnetite, are widely found running reticulately through mineral particles, crystals and cleavage cracks in association with metasomatic alteration in the mafic-ultramafic xenoliths and their host rocks.

经岩相学和电子探针及扫描电镜分析发现，伴随交代蚀变，寄主岩和各类镁铁-超镁铁质包体岩石中，普遍发育沿粒间和矿物晶体裂隙或解理纹贯入或穿插的黑色不透明物质，主要由微晶硅酸盐矿物和磁铁矿组成。

The results showed that the MS2 fragmentation pathways of DASSSB were affected by the character and position of substitutes on salicylidene phenyl. The C=N cleaving to form fragmentation ion [M+H-283](superscript +) was dominant for DASSSB compounds with electron-donating group on the C4 of the salicylidene phenyl; while fragmentation ion [M+H-254] (superscript +) forming by C-C cleavage of the β-position of C=N was dominant for DASSSB compounds with electron-withdrawing group on the C5 of the salicylidene phenyl.

结果显示，这些化合物的ESI-MS/MS裂解方式与它们分子中水杨醛苯环上取代基的性质和位置有关：当水杨醛苯环上4位连接供电子取代基时，分子以CN双键断裂为主，生成[M+H-283]碎片离子；当水杨醛苯环上5位连接吸电子取代基时，分子以CN双键β位的C-C键发生断裂为主，生成[M+H-254]碎片离子。

The result shows that when ColE7 is bound to its prefer sequence, the DNA main chain was distorted the most and the scissile phosphate was located closer to the endonuclease active site, thus leading to a more efficient cleavage.

分析ColE7与DNA的复合晶体结构后发现，当ColE7与其偏好的序做结合时，其DNA主链的构型有相当明显的变化，且scissile phosphate较靠近活性中心区，可能因此导致较高的活性。

A series of mono-, sesqui-, di- and tri-terpenoids with various structural types, which produced by bio- oxidation, hydrogenation, hydrolyzation, esterification and cyclic cleavage toward-limenone, were analyed by GC-MS.

经GC-MS分析发现该两细菌对-柠檬烯有显著的生物催化转化作用，能对底物进行不同程度的氧化、还原、水解、酯化、开环等反应，并产生丰富的系列结构不同的其它萜类化合物：包括单萜、倍半萜、二萜、以及三萜等。

A high cutting efficiency required the acid environment and urea as a solutizer had an advantage over 70% formic acid in facilitating cleavage.

高效率的切割需要在酸性条件下进行；以尿素作为促溶剂比70%的甲酸更有利于小肽的切割。

METHODS: The breast cancer cell lines Bcap37 were treated with different concentrations of vinblatine dissolved in dimethyl sulphoxide or caspase-3 inhibitor (DEVD-CHO, 100 μmol/L) for 3 h. The changes of the proliferation were detected by MTT methods. The apoptosis was determined by observing the internucleosomal DNA cleavage and PI staining, and the proteins of pro-caspase-3 and IκΒ-α were detected by Western blotting methods.

用二甲基亚砜对照、100μmol/L caspase-3抑制剂预处理乳腺癌Bcap37细胞3h后，加入不同浓度的长春碱，以MTT法检测肿瘤细胞增殖能力，以细胞DNA片段分析及PI染色法检测肿瘤细胞凋亡，以蛋白免疫印迹法检测pro-caspase-3和IκΒ-α蛋白的变化。

The result is consistent with previous studies. Whereas, tapetal cells of sterile anthers were disintegrated since tetrad cells were disjoined, indicating that disintegration of tapetal cells is earlier occurred in sterile anther than that in fertile anther. DNA ladder revealed that the cleavage of nuclear DNA into oligonucleosome-sized fragments to

结果表明，在花粉母细胞减数分裂后的四分体解离时期，不育花药的绒粘层细胞较可育花药提前开始裂解；在不育系S-Mo17rf3rf3花药和花粉S-(rf3)中均明显出现PCD过程的DNA片段化以及线粒体细胞色素C外渗的现象，证明了玉米CMS-S的花粉败育与花药绒粘层细胞的提前凋亡和小孢子细胞的细胞程序性死亡有关。

The results showed that the rupture is transcrystalline cleavage cracking by hydrogen embrittlement basically,i.e.cathodic stress corrosion cracking.

指出管件破裂基本上属氢脆引起的穿晶型解理开裂，即阴极型应力腐蚀破坏。
