二甲苯

Solubility of nitrobenzenamine in xylene was higher than that in toluene,but solubility of etherate was nearly the same in the two solvents.

硝基苯胺在二甲苯中的溶解度要大于甲苯中的溶解度，而醚化物在两种溶剂中的溶解度相当。

Solubilities of 4,5-dichloro-2-nitrobenzenamine and etherate were experimentally determined.

测定了4，5-二氯-2-硝基苯胺和醚化物在二甲苯和甲苯中的溶解度。

Protection for sleeve, marking and sealing materials on capacitor body will not be damaged, which shouldnever be washed or cleaned by halogenous agents or solvents such as trichloroethylene. Xylene or acetone etc.

为了保护塑胶套管，印刷标示以及封口材料不被破坏，电解电容器不得以卤化化学药品或类似溶剂作为电解电容器洗涤之用，如三氯乙烯、二甲苯类或酮类等。

In this paper, using Liaoning\'s Ca-bentonite as matrices, modifying with sodium compound at first, organically modifying with Octadecyl/Hexadecyl ammonium chloride as the cover agent, based on hydrothermal process, and dispersing the modified bentonite into the dimethyl benzene-methyl alcohol system fully, we synthesized the high-grade organic bentonite gel with stable quality and excellent characteristics.

本文以辽宁钙基膨润土为原料，首先对其钠化提纯，然后以十八／十六烷基氯化铵为有机复合剂，采用水热合成技术对膨润土进行有机改性，将改性膨润土充分分散于二甲苯-甲醇体系中制备出产品质量稳定、性能国内领先的膨润土高档有机凝胶矿物材料。

At the same time, some of the pyrolysates are the important favors in cigarette smoke, such as isophorone and megastigmatrienone, etc. The amounts of these pyrolystaes alter with the change of pyrolysis temperatures and the concentration of oxygen. the lutein is applied to cigarettes as flavoring.

分析结果表明，叶黄素的裂解产物主要是甲苯和对-二甲苯等苯及其同系物、1，2–二氢-1，1，6-三甲基-萘和2，7-二甲基萘等萘及其同系物，另外还生成氧化异佛尔酮和巨豆三烯酮等酮类物质和烯烃类物质等，这些物质随着裂解温度和裂解氛围的变化，其种类和峰面积归一化百分含量有所不同。

Then the index of ulcer was measured and the ulcer inhibitory rate was measured.Results: The weight of ear of mice treated with XSG was reduced compared with that of normal group,and the joint swelling of rat was less than that of normal group. The latence of sole-ache caused by hot-plate and bellyache caused by acetic were both delayed and the times of skewing body within 15 minute were reduced compared with that of the normal group.

结果：香砂六君颗粒对小鼠二甲苯性耳廓肿有明显对抗作用；对大鼠蛋清性关节肿有一定对抗作用；对热板和醋酸所致小鼠疼痛香砂六君颗粒能明显延长其舔足潜伏期和减少扭体次数；对大鼠利血平型及乙酸型胃溃疡香砂六君颗粒组的溃疡指数从模型组的46.26±1.64mm2和23.02±2.05mm2减少为34.75±0.82mm2和13.84±1.2mm2；对大鼠利血平型及乙酸型胃溃疡香砂六君颗粒的溃疡抑制率分别为51.43%和39.87%。

The content of benzene compounds extracted by methane dichloride from the leavy surfaces of trees inside the factory areas reached to 88. 33 mg/kg, the levels of benzene, methylbenzene and dimethylbenzene were 36. 680 mg/kg, 10. 22 mg/kg and 41.43 mg/kg respectively in the coking factories.

厂区内植物叶片表面二氯甲烷提取物中苯系物含量高达88.33mg/kg，其中苯36.680mg/kg，甲苯10.22mg/kg，二甲苯41.43mg/kg。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
