酸根

This paper proposes that weak acid is a coordination compound that regards hydrogen ion as "coordination body" and regards acid radical as central atom.

本文首次提出将弱酸看成是以氢离子为"配体"，以弱酸的酸根为中心"原子"所形成的"配合物"，通过计算该"配合物"的生成函数N并绘制PH－N图，用Bjerrum，N。

The dechroming mechanism of organic acid from chrome shavings was studied from the following aspects,the depolymerization of complex compound,the replacement of H+ and the replacement of organic acid radical anion.

从络合物解聚、氢离子取代和有机酸根阴离子取代3个方面，探讨了有机酸的脱铬机理，认为氢离子的取代和有机酸阴离子的取代起主要作用。

Application: in medical industry, sodium citrate is the carrier of sodium ion, lemon acid radical can participate in tri-acid sodium body circulating of organism rapidly in human body, the sodium ion stores in the body, so it is often used as antipyretic and the correction pharmaceutical of the acidity of the urine in the medical treatment.

用途：在医药工业上，柠檬酸钠是钠离子载体、柠檬酸根在人体内可迅速参与机体的三钠酸循环，钠离子则在体内储备，因此医疗上常用作退热剂，尿酸度的矫正剂，同时由于其抗凝作用，因此是医疗上重要的抗凝血剂。

In this paper, adipate -intercalated LDHs were prepared by direct anion exchange method,acidic one step synthesis method and alkaline one step synthesis method,and were characterized by XRD and IR.

Under the conditions without air, oxygen may adsorb on the I-modified surface of electrolytic silver.

在甲醇和氧共吸附的情况下，表面可以检测到甲氧基和甲酸根。

When adding dianion 5 to aldehyde 4 and using the molar ratios of entry 1, the yield of aldol 3 dropped from 98% to 86%, and 7% of alcohol 7 was formed.

当加入醛酸根5比4，用摩尔进入一日产量3醛从98%下降到86%，而77%的酒精组成。

The formula for calculating critical alkalify leaching was also adjusted by considering the effects of bicarbonate leaching, organic acid leaching, aluminum species, and Al-organic acid complexation, which makes the theory more applicable.

另外，考虑碳酸氢根淋溶、有机酸根淋溶、铝的形态和铝同有机酸的络合等因素，对临界碱度淋溶的计算公式进行了修正，使得稳态法的应用范围更加广泛。

Arenedisulfonates have much stronger coordination ability to alkali, alkaline earth than to transition metal ions.

芳烃二磺酸根离子与碱金属离子和碱土金属离子的配位能力比过渡金属离子强。

The antitumor activity of platinum complex of ammine/amine (NH3/CH3NH2) with oxalate was determined by MTT and SRB methods in vitro. At the same time, the anticancer mechanism was studied by flow cytometry, Giemsa and Icp-Ms.

采用MTT和SRB法研究了混胺(NH3/CH3NH2)草酸根合铂混配配合物对人体癌细胞的增殖抑制作用，又通过流式细胞法、Giemsa染色法、等离子体质谱法研究了它的抗癌机制。

重铬酸根与磁场对铁在硫酸溶液中阳极极化行为的影响。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
