查询词典 acid group

Over the past year, the group evaluated the seven-year follow-up results of therapeutic effects of all-trans retinoic acid and arsenic trioxide (As2O3) combined treatment in newly diagnosed acute promyelocytic leukemia. We also studied the mechanism of therapeutic effects of Imatinib and As4S4 combined treatment in CML cell line and animal model. These two papers were published on PNAS.

过去的一年中，本课题组总结完成了全反式维甲酸和三氧化二砷联合治疗初发急性早幼粒细胞白血病的七年临床随访资料的疗效评估；在慢性粒细胞性白血病，完成了应用As4S4和STI571联合治疗作用的细胞、分子和整体动物水平的机制研究，这两部分工作均已发表于PNAS。

Another problem is a group of chemicals called borates, including boric acid.

一类名为硼酸盐的化学物质引发了另一个问题。

Firstly, XRD, TEM and FT-IR were used to characterize the structure of CNTs treated by dense HC1, dense HNO_3, HNO_3, H_2SO_4-HNO_3, K_2Cr_2O_7-H_2SO_4 and bromic acid. The results showed that purification treatment had no change on the structure of CNTs. But on the top of CNTs have function group such as -OH and -COOH after H_2SO_4-HNO_3 and K_2Cr_2O_7-H_2SO_4 were treated.

采用浓HCl、浓HNO_3、H_2SO_4-HNO_3、K_2Cr_2O_7-H_2SO_4、溴水共5组物质分别对CNTs进行纯化处理；借助XRD、TEM、FT-IR等分析手段对处理前后CNTs结构及形貌进行表征，发现以上5种物质纯化处理并不会对CNTs结构造成很大影响，其中H_2SO_4-HNO_3和K_2Cr_2O_7-H_2SO_4处理效果较好，除杂的同时CNTs端口带上-OH或-COOH活性官能团。

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。
