The different catalytic systems are discussed. The results show that sodium tungstate has effective catalytic ability.

实验结果表明，钨酸钠和双季铵盐催化体系能在温和的条件下，催化稀过氧化氢溶液氧化环己醇、苯甲醇、环己烯。

But when the concentrations were too low, micropatterns would have large shrinkage due to the volatilization of solvents.

但溶液浓度过稀时，由于大量溶剂的挥发，所制备的条纹会有较大的收缩率，这会给精确复制微结构带来困难。

Pretreatment of wood chips with dilute oxalic acid solution for about 10 minutes reduces electrical energy requirements for mechanical pulping by 25%, improves paper strength properties, reduces pitch content, improves dewatering, and produces value-added chemicals enabling a biorefinery dimension.

将木片用稀草酸溶液预处理10分钟减少木浆电能源需求的25%，提高纸张强度性能，降低了沥青含量，提高了脱水，并精炼厂产生增值化学品。

The concentration of nisin release from zein edible film increases gradually and then decreases slowly at the same temperature.

在同一温度下，乳酸菌素释放到稀盐酸溶液中的活力单位的浓度随着时间的变化先增大然后减小。

By agar diffusion assay changes of nisin release from zein edible film with time and temperature were assayed.

采用琼脂扩散法研究了玉米朊复合薄膜中乳酸菌素在稀盐酸溶液中释放的活力随着时间和温度的变化。

Heated in a boiling water bath, penicillin antibiotics such as amoxicillin, ampicillin, sodium cloxacillin, sodium carbenicillin and sodium benzylpenicillin could react with K3[Fe6] to form combined products in a dilute HCl medium. As a result, resonance Rayleigh scattering intensity was enhanced greatly and new RRS spectra appeared. The maximum scattering wavelengths of the five combined products are all located at 330 nm.

在稀HCl介质中，K3[Fe6]与阿莫西林、氨苄西林、氯唑西林钠、羧苄西林钠和青霉素钠等抗生素药物在加热条件下反应生成结合产物，会导致溶液的共振瑞利散射强度急剧增强，并产生新的RRS光谱，5种反应产物的最大散射峰均位于330 nm附近。

This paper deals with making stop bleeding sponge with dried small shrimps. Firstly breaking away with inorganic salt and proteir in the dried small shrimps with acid and NaOH, secondly, taking off vinyl-in the chitin with 50% NaOH, temperature is 110 ℃. the last, reacting with chitosamine and PVA-124 make stop bleeding sponge were produced, catalyst is PdCl 2. The sponge film and sparkce is setatisfaction.
