Their half lives were 27.29 and 69.16 days respectively. Monocrotophos degraded into both methanol extractable and unextractable residues in the submerged soil.The analysis of 14C-methanol extractable. residue by TLC and ARG indicated that degraded products of monocrotophos were triether phosphate,;N-de-methyl Azodrin, O, O-dimethyl-vinyl-phosphatc,O-demethyl Azodrin,and O, C-demethyl Azodrin.The principal degraded extratable product of monocrotophos was triether phosphate, which incresed from 5% of the parent solution of monocrotophos to a range of 28-83%, furthermore and its degradation process was much faster in the unterilized soil than in the sterilized soil.

久效磷在淹水土壤中降解为甲醇可抽提态和不可抽提态残留物，对甲醇可抽提态残留物经TLC和红外光谱分析表明，其降解物为磷酸三酯、N-去甲基久效磷、O，O-二甲基乙烯基磷酸酯，0-去甲基久效磷，以及O，C-去甲基久效磷，但主要为磷酸三酯，其含量由母液中的5％增加到28—83％，这种降解过程，在未灭菌土壤中比在灭菌土壤中快。

After the graft reaction of ungelatinized starch, the morphology of the copolymers kept the aggregate structure of starch, and vinyl copolymer is grafted on its surface; while the gelatinized starch forms homogeneous polymer which is totally different with ungelatinized products.

结果表明，合成的淀粉接枝共聚物符合预期结构，未糊化的淀粉接枝后，聚合物保持团粒结构，表面接枝上了乙烯基均聚物；糊化的淀粉接枝后，形成了均匀的淀粉接枝共聚物。

The basic range of FUCHEM VER are unpromoted and required the addition of both accelerators and promoters just like general UPR. The selection criteria of the curing system and amounts depend on the desired gel time, the temperature of both the resin and workshop, the laminate thickness, humidity, impurities and the posting-curing possibilities.

FUCHEM系列乙烯基酯树脂一般为非预促进树脂，固化系统与通用不饱和树脂类似，在室温或90℃以下固化时，应该加入固化剂和促进剂，但因根据成型工艺、作业温度、制品厚度、湿度大小等调整相应的加入量，同时根据不同的情况选用不同类型的固化系统。

The iPod was the product of imagination -- if you asked people in the days of vinyl and cassette tapes how they would like the distribution of recorded music improved, you would have received responses anchored to the Current State of the time: make records unscratchable; make cassettes that you don't have to turn over to play the other side.

因此，我们不知道自己需要什么。iPod是想象的产物——如果你在那些只有乙烯基和盒式录音带的岁月里向人们询问：你们打算怎样改善录制好的音乐唱片的销售？你听到的将是类似于现在情形的回答：让唱片不会被划掉；制作无需换面播放的盒式磁带。

Lead is also used in some ceramic and vino vinyl products, candles, hair coloring and other goods.

铅也被用于制造陶瓷和乙烯基产品、蜡烛、染发剂和其他产品。

The role of vinylene group in geometry,electronic structure and spectra property is analyzed according to the comparative study of the dyes.

Conductivity of Polyoxyethylene/Poly (2-vinyl pyridine)Blend and Compatibilizing Effect of Lithium Perchlorate;2. Graft terpolymerization of polyoxyethylene macromer with acrylates;3. Then multiblock copolymers was obtained by condensing polyoxyethylene and poly(2 vinylpyridine)with dichloromethane in the presence of potassium hydroxide.

甲基萘锂作为引发剂利用阴离子聚合得到 2 乙烯基吡啶的遥爪双羟基低聚物(P2VP)，然后以二氯甲烷作偶联剂与聚环氧乙烷反应制备P2VP和PEO多嵌段共聚物，考察了反应时间对偶联反应的影响，并对共聚物进行了IR和1H NMR表征，由1H NMR谱的积分曲线得到了共聚物中PEO链段质量分数。

The premium theme is further emphasized by the thick carpeting, vinyl roof lining, and special DS badging.

保费的主题是进一步强调了厚厚的地毯，乙烯基屋顶衬里，特别德尚徽章。

Canopies with a vinyl window to let you keep an eye on the baby, come with many strollers.
