The measurements of self-diffusion coefficient,spin-spin relaxation and interproton distance at 318 K suggest that N,N′-bis-α,ω- alkane propane diammonium dibromide (16-3-16) quasi-global micelles are formed in the dilute solution at a concentration of 0.26 mmol/L and the head groups are in a saw-toothed form staying at the surface of the micelle to overcome the strong electrostatic repulsion force.

从自扩散系数、横向弛豫和质子距离等NMR测定参数推测，在浓度为0.26 mmol/L（318 K）的N，N′-双-α，ω-丙烷溴化铵(16-3-16)溶液中形成了近似球形的胶束，胶束表面的带正电荷的铵基极性头呈锯齿状排列以减弱分子间静电排斥力的影响。

This is inturn easily dissolved in a dilute solution of HCl, precipitating out H2SiO3 and leavingAlCl3 solution. Thus it is possible easily to separate the main components Al2O3 andSiO2 in the fly ash materials.

研究采用以Na_2CO_3为配料的固相热分解反应的方法，使高铝粉煤灰中的莫来石和铝硅酸盐玻璃相转变成霞石(NaAlSiO_4)。

The sodium cyanide solution can be diluted by adding water.

加水可以稀释氰化钠溶液。在化学专业中，dilute意为"稀释"。

In order to improve their water solubility, 4"-fatty amido-3"-sodium carboxylate azobenzene-4-sodium sulfonates were synthesized. They are azo compounds with two hydrophilic groups of carboxyl and sulfonyl. They decrease the surface tension in dilute solution slowly, and show some surfactivity, but are not surfactants. The probable reason is their relative strong hydrophile. Furthermore, their colors are not fresh and far from our destination.

为了改善其水溶性，改用对氨基苯甲酸为原料合成了4′-脂肪酰氨基-3′-羧酸钠偶氮苯-4-磺酸钠盐，以偶氮结构为主的亲水基团上连有羧酸基和磺酸基两个亲水性较强的基团，但可能由于其亲水性太强，在稀溶液中只能缓慢地降低溶液的表面张力，具有一定的表面活性，但不是表面活性剂，而且颜色不鲜艳，距离我们的目标较远。

Based on a simple cluster theory recently proposed for the dilute solution viscosity of monodisperse polymer, the concentration-dependence of dilute solution viscosity of polydisperse polymer was investigated.

依据最近提出的关于单分散高分子的稀溶液粘度的团簇理论，对多分散高分子的稀溶液粘度的浓度依赖性进行了更新的理论分析。

The dilute solution of the absorption apparatus of the refrigeration system serially backflows to the low, middle and high temperature solution heat exchangers and generators in turn and reflows to the absorption apparatus finally, thereby achieving the reasonable utilization of different grade energy and having relative high thermal efficiency of the unit.

该制冷系统吸收器的稀溶液串联倒流依次进入低、中、高温溶液热交换器和发生器，最后流回吸收器，能够实现对不同品位能量的合理利用，其机组热效率也相对较高。

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

这两个团体间的分歧难以掩饰。
