介绍了一种新型耐寒增塑剂尼龙酸二正丁酯的合成工艺，用价廉、易得的尼龙酸(由制己二酸母液中获得的C4～C6混合二元酸)及正丁醇为原料，浓硫酸为催化剂，经酯化、脱醇、中和、沉降及减压蒸馏等工序而制得产品。

Adopting condensation copolymerization between alkylphenol polyoxyethylene ether and methyl aldehyde and using concentrated sulfuric acid sulfonation, which it with sodium hydroxide neutralization, finally acquired sulphonate anionic surfactant, utilize as temperature resistance 、mineral salt tolerance for heavy oil viscosity reducer , research on the performance evaluation, the result indicate, the amount of sulphonate anionic surfactant to be used at 0.2wt%, viscosity reducer rate reached 92.1%; added with 0.5wt%, the calcium and magnesium ions resistance in mineral water up to 800mg/L.

采用辛基酚聚氧乙烯醚和甲醛的共缩聚物与浓硫酸磺化后，再用氢氧化钠中和后得到磺酸盐阴离子表面活性剂作耐温抗矿盐稠油降粘剂，并对其进行性能评价，结果表明，辛基酚聚氧乙烯醚甲醛共缩聚物磺酸盐阴离子表面活性剂加量为0.2wt%时，降粘率高达92.1%，抗钙、镁离子能力达800mg/L。

The method of acid-base titrations combined with UV is suitable and accurate for determining compound benzoic acid tincture.

结合使用中和法和紫外分光光度法能较好地同时检测复方苯甲酸酊剂中两种主要成分的准确含量。

This article had carried on the transformation to the ramee retting wastewater processing project which mainly used the method of "the transformation-biological chemistry" for the polymerization iron sulfate or the polymerization aluminum chloride.

对苎麻脱胶废水处理工程进行了改造，采用了&物化－生物化&组合工艺和企业锅炉烟气对苎麻脱胶废水进行中和处理，以废治废；采用硫酸亚铁、聚合硫酸铁或聚合氯化铝为絮凝脱色剂，去除大量的非溶解性污染物。

When purify carries the suspension colloid grain of negative electric charge in natural raw water, it is OK that its element linear grows the positive electrical charge that contains in catenary to be opposite remove electric sex to counteract the double function that reachs adsorption to bridge at the same time, and water-solubility of starch of this kind of modified is good, burnt viscosity is stable, cast impose kind agile, it is a kind of function exceedingly good organic, inorganic and compound high polymer garrulous coagulates agent.

在去除天然原水中带负电荷的悬浮胶体颗粒时，其分子线性长链中所带有的正电荷对可以同时起到电性中和及吸附(物质表面吸住周围介质中的分子或离子现象)架桥的双重功能，而且这种改性淀粉水溶性好，糊粘度稳定，投加方式灵活，是一种性能优异的有机-无机复合高分子絮凝(使液体中悬浮微粒集聚变大或形成絮团，从而加快粒子聚沉，达到固-液分离的过程)剂。

The dosage is determined by pH control approach, which does not require a routine jar test. This method can simultaneously determine the optimal pH and economical dosage for oxide-CMP wastewater. The coagulant can be added directly into the raw water without the pH adjusting at first. According to this method, the coagulant acts like a titrant and the pH of the oxide-CMP wastewater is monitored. The optimal dosage is the one that corresponds to a specific pH.

本论文主要以「pH控制法」来决定线上加药剂量值，其与传统瓶杯试验不同的是，其加药逻辑可直接对线上加药进行控制且毋须定期确认参数。pH控制法视混凝剂为酸滴定药剂，直接对进流之氧化层研磨废水进行加药，及至特定pH时，加药停止，此时之加药量即为电性中和去稳之控制点，远较过量加药法经济。

Sodium bicarbonate is an antacid which neutralises hydrochloric acid produced in the stomach.

碳酸氢钠是一种抗酸剂可以中和由胃产生的HCL。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
