- The kinetics of homogeneous precipitation was studied , the activation energy was about 100 . 19kj / mol , and reaction index was 1 . 42
经稳定态假设处理后,得到沉淀反应的表观活化能为100 . 19kj mol ,硝酸钴的反应级数为1 . 42 。 - Based on the preparation of silica in a rotating packed - bed reactor ( rpbr ) , an in - situ modification of silica is carried out by addition of silicane coupling agent during the final stage of carbonization reaction
摘要在超生力反应沉淀法制备白炭黑的基础上,在沉淀反应的后期加入矽烷偶联剂,实现沉淀法白炭黑的原位改性。 - It also shows that the dispersant is added before reaction will be better than after . so the dispersant is an effective way to eliminate water from the gel . therefore , the agglomeration state in the obtained powder was well controlled by adding dispersant
通过适当的后处理,沉淀反应前和反应后添加分散剂的工艺制得的- al _ 2o _ 3的一次颗粒分别为27nm和30nm ;其二次颗粒的平均粒径分别为40mm和50mm ,且前者团聚程度较轻。 - The results from sds - page presented that there were three female specific protein subunits with molecular weights of 123 kd , 120 kd and 91 kd , respectively . we can conclude the higher molecular compose of two subunits ; the results from two dimension electrophoresis showed the isoelectric points of two female - specific spots with molecular weight of about 120kd were 5 . 5 and 5 . 7 . immunodiffusion reactions demonstrated that vg existed both in female fat body and hemolymph , which as vn was deposited in the ovary , while not in the male
Page电泳结果表明:丽蝇蛹集金小蜂明显存在2条雌特异性带-卵黄蛋白,分子量分别为181kd和136kd ; sds - page电泳分析:存在3条雌特异性带,其分子量为123kd 、 120kd和91kd ,由此,可推定卵黄原蛋白( vitellogenin , vg )和卵黄磷蛋白( vitellin , vn )由2个蛋白组成,其中分子量较大的蛋白由2个亚基组成;双向电泳结果显示,在120kd附近有两个特异性点,其等电点为5 . 5和5 . 7 ;双扩散表明,丽蝇蛹集金小蜂卵黄磷蛋白的抗血清与雌隐成虫虫体、脂肪体、血淋巴和卵巢匀浆液均有免疫沉淀反应,而与雄蜂血淋巴无免疫反应,说明了vg与vn具有免疫同源性,是雌特异性蛋白,且由脂肪体合成。 - In this paper , concentrated sulfuric acid and titanium dioxide are used to prepare the tios04 solution that test later required under long time heat . the influences of reaction time and reaction temperature to yield of tioso4 are discussed . in the experiment of preparing tio2 powder , reaction temperature , ph values , material ratio , operation way , velocity of feed , calcining heat and time are researched by the principle of nucleation and growth in thermodynamics and kinetics
在制备tio _ 2粉体实验中,根据成核生长的热力学和动力学原理,深入分析了沉淀反应时环境的温度、 ph值、反应物配比、操作方式、加料速度等因素对ti ( oh ) _ 4粒度的影响,以及焙烧温度和保温时间等因素对制得的纳米tio _ 2粉体性能的影响,得出了制备锐钛型纳米tio _ 2粉体的优化工艺条件。
