查询词典 percentage composition

By setting the retting duration of 20 hours, the factors affecting the residual gum percentage of the retted kenaf fibers are studied. The experimental results show clearly that the following factors have the significant influence on the residual gum percentage of the retted kenaf fibers and show the obvious variation tendency. The preferred processing parameters are as follows: pH value 7. 0、bath ratio 1: 50、reuse percentage of retting liquid 50%、air flow volume 2. 5L/min、temperature 40℃、nitric additives (ammonia is better than nitrates) percentage 0.45%.By comparison with anaerobic retting, the retting duration using aerobes is much shorter than that using anaerobes.

for long time, the primary school living to the writing widespread existence "sorrow, afraid, be disgusted with" of thought.but the composition teaching of tradition, the teacher set question from the composition, purpose, choose a material, row to lift a key link to the workbook to review to change, whole one person contract for and resulted in thus student can according to teacher design good"diagram paper" lay bricks, the composition contents be deceitful and empty and lack a kid true, monotonous phenomenon, complete deprival student's workbook of independence power.in fact, composition's being not only be the operation of the language sign.left a person of development, left life, composition will is have no the wood of origin, have no source of water.

长期以来，小学生对写作普遍存在着"愁、怕、厌"的思想。而传统的作文教学，教师从作文命题、立意、选材、列提纲到习作评改，全一人包揽，从而造成了学生只能按教师设计好的"图纸"砌砖，作文内容虚假、空洞，缺乏童真，千篇一律的现象，完全剥夺了学生习作的自主权。其实，作文并非仅是语言符号的操作。离开了人的发展，离开了生活，作文就将是无本之木，无源之水。

The acidic composition can be prepared by mixing a monovalent or polyvalent cation and an organic acid in the presence of a strong oxyacid, wherein the resultant acidic composition is less corrosive to a ferrous metal than a solution of a mineral acid having the same acidic pH value as that of the acidic composition, and where in the acid composition is more biocidal than a mixture of the organic acid and a metal salt of the organic acid which mixture has the same acid normality value as that of the acidic composition.

所述酸性组合物可以在一种强羟基酸存在时，通过混合单价或多价阳离子和有机酸来制备，其中与具有相同的酸性pH值的无机酸溶液相比，所形成的酸性组合物对含铁金属的腐蚀性更小，并且与具有相同酸当量值的有机酸与有机酸金属盐的混合物相比，所述的酸组合物具有更强的杀生物作用。

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。

This paper gives a simple idea about the problems existing in students' writing: 1 psychological blockage, such as anxiety, lack of interest so on and so forth. 2 Chinglish frequently appears in Chinese students' composition. That is to say Chinese students often use Chinese way of thinking to writing English composition. 3 When Chinese students write, they usually commit intralingual error. Intralingual error is the mistake that students often make when they choosing words, making sentences. It also includes grammar mistake. 4 Chinese students often don't know how to organize the ideas when they face the composition topic. As a result, the compositions written by most of Chinese students don't have clear topic sentence. 5 Chinese students' compositions are usually very boring and dull. Based on the problems that exit in Chinese students' composition, this paper put forward five teaching strategies: 1 English teachers should foster positive emotion when they teach writing.

本课题简单阐述了中学生英语写作中普遍存在的5个问题：1、对英语写作存在心理障碍，比如畏惧心理等；2、中学生英语作文存在大量"中国式英语"，即学生经常借用汉语思维进行英语写作，使得文中出现不符合英文习惯的句子和表达；3、中学生在进行英语写作时经常犯言内错误，言内错误指学生在用词，造句及句法等方面经常容易犯的错误；4、中学生在面临所给的作文题目时不知道如何审题，写出来的作文中心思想不明确；5、中学生英语作文普遍存在内容单调贫乏的问题。

are as follows:（1）The starting reaction temperature of B/Pb 3 O 4 and B/BaCrO 4 delay compositions are independent of the proportion of the delay composition, it is about 415℃ and 780℃, But that is about 713℃ of B/CuO delay composition when B in the delay composition is in 3%~5%, and 662℃ when B is 7%~10%,（2）The reaction heat is augmenting with the augment of B in the boron series delay composition.

主要结论有：（1）B/Pb 3 O 4 和B/BaCrO 4延期药的反应起始温度分别在415℃和780℃左右，与配比没有关系；硼含量为3~5%，B/CuO延期药的反应起始温度在713℃左右，硼含量为7~10%，在662℃左右。（2）硼系延期药的反应热随硼含量的增大而增大。
