查询词典 surfactant

The results show that the surfactant species impact apparently on the purity, dispersion degree and particle size of the reducing sample. The non-ion surfactants can improve the dissemination of ultrafine silver particles, but both the dispersive effects of cation and anion surfactants are unapparent.

In the disposal process of surfactant wastewater, flocculation technology is usually used as a pretreatment method. The flocculation process of this kind of wastewater is very complicated because of its complicated components and unconstant characteristics.

在表面活性剂类废水的处理过程中，混凝工艺作为预处理手段经常被采用，但由于该类废水成分复杂、性质多变，使得其混凝过程也较为复杂。

In the second part of this dissertation, the oxidation reaction of veratryl alcohol catalyzed by ligninase in the presence of surfactant have been first studied by spectrophotometric technique.

本论文的第二部分工作就是以藜芦醇的氧化反应为指示反应，首次就表面活性剂对木素过氧化物酶的头基效应以及非离子表面活性剂存在下酶促反应动力学和过氧化氢抑制动力学展开了研究。

The fluorescent intensity ratio of the first vibronic peak (λ=373 nm) to the third vibronic peak (λ=383 nm) of pyrene solubilized in micelle decreased gradually, which was different from the conventional surfactant, such as SDS. The aberrant property indicated a broad micelle size for the m+nAr-T surfactants. That is, the aggregates of the studied surfactants gradually grew in size with increasing concentration over wide concentration range.

与传统表面活性剂不同，增溶于N-酰基牛磺酸钠胶团中的芘的第一个电子振动峰(λ=372nm)的荧光强度I1和第三个电子振动峰(λ=385nm)的荧光强度I3之比I1/I3值随着表面活性剂浓度的增加而缓慢降低，说明了N-酰基牛磺酸钠表面活性剂在低浓度区形成疏松的聚集体，随着浓度的增大则有更多的表面活性剂分子挤入已形成的聚集体。

It was to study the expression and signification of pulmonary surfactant-associated protein-A in the vaginal fluid of recurrent vulvovaginal candidiasis.

旨在探讨肺表面活性物质相关蛋白A在复发性外阴阴道假丝酵母菌病患者阴道分泌物中的表达及意义。
