查询词典 percentage composition

In my opinion, Cu complexes with unsaturated alcohol to form a complex compound; the nitrogenous compound introduced serves as the complex compound's stabilizing agent and reduces activation energy of reaction; TMPO serves as oxygen carrier and displays it's selective oxidation function. This new method and mechanism also demonstrates significance to other similar organic reactions.3 In the chlorohydrin reaction, NaCIO is replaced by Ca2see Chapter4.4.3.4(2 .A, this method hasn't been reported in previous literature,which exerts more buffer action to the react system, the yield increased from 52% to 88.6%; at the same time it solve the problem of poor stability and low percentage composition of NaCIO.

认为：CuD与烯醇形成络合物：含氮有机物的引入起到稳定络合物，降低活化能的作用：而TMPO则充当携氧子起传递氧的作用，并具有选择氧化功能：这种新的方法和理论对类似的反应(不饱和醇类在络合体系下选择性催化氧化为对应的醛也具有重要的指导作用。3在异戊二烯的氯醇化反应中，用次氯酸钙代替次氯酸钠见第4章4.3.4(2.A，本方法未见文献报道，使反应系统更加温和，收率由52%提高到88.6%：并解决了次氯酸钠稳定性差、有效氯含量低的实际问题，具有重要的实用意义。

The result of analysis of maize quality indicates that under enhanced UV-B radiation, there is different influence on the percentage composition of soluble sugar of different varieties, and the tendency and amplitude of content variation of glucose, levulose and sucrose are different. The percentage composition of starch decreases, and lysine and protein increase. The variation tendency and amplitude of the protein with differentsolubility are different. The change of chemical quality in maize seeds is marked, and the effects of UV-B radiation are different with different maize variation.

UV-B增加对玉米品质影响的分析表明：UV-B增加处理下玉米的可溶性糖百分含量的变化不同的王米品种有着不同的表现，且葡萄糖、果糖、蔗糖变化的趋势及幅度也是不同的；淀粉百分含量是降低的；赖氨酸及蛋白质的含量比对照组要高；不同溶性的蛋白质受到影响后其变化趋向及幅度均不相同，玉米籽粒化学品质的变化是显著的；不同的玉米品种受到UV-B增加的影响后，其变化是不同的。

Produce the BF gas mud 100, OOOt every year. The raw mineral of puddling is the magnetite containing vanadium and titanium. The grade of iron is only 53%. The grade of sinter mineral is only 47-48%. So the percentage composition of iron is relatively low, only 29.70%. The grade of zinc is relatively high, reach 9.92%. And the percentage composition of carbon is relatively high, reach 16. 80%. In the next place, the BF gas mud is the production through sinter in high temperature.

攀钢炼铁的原矿物为钒钛磁铁矿，铁品位仅为53％，烧结矿品位为47％～48％，所以攀钢高炉瓦斯泥的铁品位也相对较低，仅为29.70％，并且含锌量高，达到了9.92％，含碳则高达16.80％；其次高炉瓦斯泥是高炉冶炼过程中的产物，SiO_2、Al_2O_3和铁部分熔融在一起，选矿难度增加。
