查询词典 benzene

No, perming agents often contains benzene, breast-feeding time, the general does not want to做头发generally hot not to dye hair, but also what is the composition of hair dye, if it is environmentally friendly, and may affect does not matter very much, If it is some small barber shop, something he is not very clear, we must carefully the.

不可以，烫发剂里经常含有苯，母乳喂养时候，一般不希望做头发，一般不要染发烫头发，还有染发剂的成分是什么，如果是环保型的，可能影响也不是很大，如果是一些小的理发店，他的东西不是很清楚的，就要慎重了。

The surface free energies and polar components of the nanosized CaCO3 modified with zircoaluminate coupling agent and palmitic acid were calculated by measuring contact angles for water and benzene on the palletized surfaces.

通过测定苯和水在改性纳米CaCO3粉末压片上的接触角，计算了改性纳米 CaCO3的表面能和极性分量，并与未改性纳米CaCO3 进行比较。

The surface free energies and polar components of PTW modified with OTS were calculated by measuring contact angles of benzene, ethylene glycol, water on the palletized surfaces.

和所有超细材料存在的问题一样，PTW表面能高，极易团聚，表面具有很强的亲水性，与有机基体的润湿性差。

Similar lamellar hybrids can be obtained from octa(y-chloroammoniumpropyl) polyhedral oligomeric silsesquioxanes dodecyl benzene sulfonic acid sodium salt C_(18H_(29)NaO_3S, DBSS. Further research shows that different POSS to surfactant ratios result in different arrangement of layers: when there exists excessive POSS, the layer is arranged in a "Alkyl-POSS-POSS-Alkyl" sequence; while on the contrary, the layer is in "Alkyl-POSS" sequence.

实验研究表明，通过调整POSS和表面活性剂的物质的量比例可以改变片层结构，发现当POSS成分大大过量的时候，片层重复单元按照&烷基-POSS-POSS-烷基&顺序排列，对应较大的层间距；当表面活性剂成分大大过量的时候，片层重复单元按照&烷基-POSS&顺序排列，对应较小的层间距。

The diagnostic vibrational modes of these complexes were predicted and assigned. Bond length, total atomic charge, frontier molecualr obital energy, molecular obital coefficience, and Mullicken Bonding Population demonstrated that electron transfer should have happened from benzene to ammonium, and therefor the charge-transfer complex should be formed.

通过复合物中的键长、原子净电荷、分子轨道能量和系数、Mullicken成键布居等量子化学参数的分析得出了铵和苯环碳原子发生作用而形成电荷转移复合物，铵和苯之间的作用包含s-π相互作用的结论。

A variety of chemical carcinogens as diverse as benzene, cigarette smoke, and nitrites can initiate and/or promote this process.

多种多样的化学致癌物如苯、吸烟、亚硝酸盐都能够引起或促进肿瘤的发生。

A variety of chemical carcinogen s as diverse as benzene, cigarette smoke, and nitrites can initiate and/or promote this process.

多种多样的化学致癌物如苯、吸烟、亚硝酸盐都能够引起或促进肿瘤的发生。

A variety of chemical carcinogens as diverse as benzene, cigarette smoke, and nitrites can initiate and/ or promote this process.

多种多样的化学致癌物如苯、烟、硝酸盐都能够引起促进肿瘤的发生。

The lawsuits alleged that ingredients in Fanta Pineapple and Vault Zero had the potential in certain circumstances to combine to form benzene, and asserted claims for breach of warranty, unfair and deceptive trade practices and unjust enrichment.

诉状中声陈，芬达菠萝饮料和Vault Zero 饮料的成分在某种情况下可能结合产生致癌物苯。可口可乐被指控违反质保承诺、从事不公平的欺骗性商业行为和不当得利。

On the contrary, the existence of electron-donating groups on the benzene ring would prolong reaction times and decrease the yields.

使用苯胺为反应底物考察了各因素的影响，在优化的反应条件下，苯胺的转化率可达到99.7％，N-甲基-N-苯基氨基甲酸甲酯的收率为83.2％。

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.

交际能力和语法的关系应该是目标与途径的关系。
