查询词典 compositions

These data were used to infer the molecular formula and the elemental compositions of all the fragmental ions through software interpretation and, by further applying fragmentation regularities of mass spectrometry, the majority of ions were fully assigned. A base peak at m/z 402 in the mass spectrum was found as the molecular ion. The fragments were created mainly from the fragmentations of the tetrahydrofuran rings and the hydroxyl group. The most fragment products contain the dimethoxy phenyl group.

利用这些数据通过软件导出了分子式和所有碎片离子的元素组成，由此进一步根据质谱裂解规律对石梓醇分子的电子轰击质谱的主要裂解碎片给出了完全的归属，质谱中发现基峰为分子离子峰(m/z402)，裂解碎片主要来自双骈四氢呋喃环的裂解和羟基引起的裂解，绝大部分裂解产物包含二甲氧基苯基基团。

From the point view of product distribution, conversion of dimethyl ether and energy consumption, with RCD plasma DME conversion was higher and was hardly affected by the residence time of dimethyl ether, and hydrogen, carbon monoxide and unsaturated hydrocarbons with RCD plasma were more than those with DBD plasma.There was no liquid product with RCD plasma, but the liquid product obtained with DBD plasma consisted of aldehydes, alcohols and methoxy-containing organic compounds, for instance, formaldehyde, methyl alcohol, dimethoxy ethane and so on.Moreover, most compositions of liquid product were methoxy-containing compounds, and the liquid product selectivity was as high as 32.23%.However, energy consumption for the reaction with DBD plasma was more than that with RCD plasma.

从产物分布、转化率及能耗上看，利用RCD所获得的二甲醚的转化率高，几乎不受二甲醚停留时间的影响，且氢气、一氧化碳和不饱和烃的含量大，几乎没有液相产物，而利用DBD能获得较多的液相产物，包括一些醇、醛和含有甲氧基的有机化合物，如甲醛、甲醇和二甲氧基乙烷，且大部分组成都是含有甲氧基的化合物，液相产物的选择性高达32.23％，但是能耗较大。

This thesis has emphasized studies on forming mechanism of dioritic quenched enclaves in the subvolcanic dikes and cryptoexplosive breccia at depth of the Zoujiashan uranium deposit, systematically studied the diagenetic ages, geochemical characteristics and Nd, Sr, Pb and Lu-Hf isotopic compositions of the Xiangshan volcanicintrusive complex and mineralization at depth of the Xiangshan ore-field.

本文重点解剖了相山次火山岩中闪长质淬冷包体及邹家山富大铀矿床深部隐爆角砾岩的成因机制；系统研究了相山火山-侵入杂岩的成岩时代及其Nd、Sr、Pb和Lu-Hf同位素组成；同时还对相山火山-侵入杂岩的岩石地球化学特征及相山矿田深部的成矿作用进行了深入研究。

These compositions may be topically administered to animals, and are useful for preventing or treating ectoparasitic infestations in warm-blooded animals for prolonged periods of time.

所述组合物可以局部投予动物并且可用于在温血动物中长时间地预防或治疗体外寄生虫传染。

There was significant difference between larvae and adult for Engraulis japonicus in fatty acid compositions, and there was significant relation between some fatty acids(18:3n3, 22:6n3, 22:5n3 and 22:5n6 ) content and length.

对鳀鱼的脂肪酸分析表明，处于早期阶段和成鱼阶段的鳀鱼脂肪酸组成存在较大的差别，并且部分脂肪酸(如18：3n3、22：6n3、22：5n3和22：5n6)和体长有显著的线性关系。

So consequencetly difference in age structure of Engraulis japonicus populations would lead to change its element compositions. Since Engraulis japonicus was one of the most important diet to high trophic fishes such as Scomberomorus niphonius and Trichiurus lepturus, Unbalance of supplying elements of potential diets would directly lead to the facts that some fish species would grow slower and smaller.

因此，鳀鱼种群年龄结构的变化导致了种群元素组成的变化，同时由于鳀鱼是上层鱼类的重要饵料，因此潜在饵料的元素供给失衡，直接导致带鱼等鱼类因鳀鱼资源衰退而生长缓慢，个体瘦小。

C, N, P and fatty acids compositions were determined in major biology of food webs based on anchovy including phytoplankton, zooplankton, Engraulis japonicus and other fishes such as Scomberomoms niphonius, Pseudosciaena polyactis in Yellow Sea.

本研究分析黄海以鳀鱼为基础食物网中主要生物的碳、氮和磷元素组成以及脂肪酸在组成，包括处于第一营养级的浮游植物、第二营养级浮游动物、鳀鱼以及蓝点马鲛、小黄鱼等鱼类。

But Duccio consulted Byzantine formularies only, and his compositions resemble the famous miniatures of the "Evangelistarium" of Rossano, or those of the great Benedictine school of Mont' Amiata.
