Excessive Al ( I Bu) 3 is dissociated into ion pair and formes an electric double layer which keeps the stability of the colloidal particles. Simultaneously, Al ( I Bu) 3 reduces Fe 3+ into Fe 2+. 适当过量的Al(i-Bu)3形成双电层,使催化剂胶粒稳定,同时将Fe3+还原成Fe2+。
By systematically putting more than 2000 Western Zhou tombs unearthed in Henan in order, tomb forms were basically researched by stages, relations between tomb formes and its owners classes were analyzed, and time sequence of Western Zhou tombs in Henan was built. 通过对河南考古发掘的近2000座西周墓葬资料的系统梳理,对墓葬的类型和分期进行了基础性研究,分析了墓葬类型与西周的阶级关系,建立了河南西周墓葬的年代序列;
On the basis of the quantitative phase analysis, it can be concluded that TiN formes at high temperature above 1200 ℃ and there is no change in its amount during conventional heat treatment; 根据定量相分析结果可以判断:钢中TiN是在高于1200℃就形成的,它的数量不受通常热处理的影响;
In combination with hardware system and RTU, the software formes a complete automation system used in railroad transformer substations. 它与系统硬件及下位机结合构成一个完整的铁路变电站自动化系统。
Individualism, as bourgeois ideology, is a value embodiment of market economy. It has the spirit of capitalism and formes the moral foundation and theories premise of market economy. 个人主义作为资产阶级意识形态是市场经济的一种价值体现,它孕育了资本主义精神,构成市场经济的道德基础和理论前提;
One is releasing latent heat that causes adjustment of thermal wind, it formes environmental field which is favourable for development of disturbances. This is a positive feedback process. 一方面是释放凝结潜热,引起热成风调整,产生更有利于扰动发展的环境场,这是一个正反馈过程。
However, there are seldom CSH gel and Ca ( OH) 2 crystal formes at the interface between the cement paste and steel tube. 在钢管-浆体界面,虽然水化程度更高,但CSH凝胶和Ca(OH)2晶体的量却很少;
During division of the animal, the body formes long and thin. 虫体分裂时,身体伸长变细。
The absorption maximum of bound neutral red is blue-shifted, relative to free neutral read which implies that neural red formes a dimer in hydrophilic environment at their binding sites. 结合至蓝膜上的中性红吸收最大值相对于自由中性红有明显的蓝移,说明了结合中性红是以双体形式存在于亲水环境中。
RNNs are characterized by interconnection of a large number of neural units, which formes highly nonlinear dynamical systems. 其典型特征是大量神经单元通过局部互连组成高度非线性动力系统,每个神经元可由线性和非线性模拟电路实现。
The current application transfer structure formes contain: beam transfer structure, plate transfer structure, box type transfer structure, truss transfer structure. 当前应用比较广泛的转换层结构形式主要有:梁式转换结构,板式转换结构,箱型转换结构,桁架转换结构等。
Earth formes about 100 billion tons per year plant organic matter, is the most widely distributed in nature, the most abundant, inexpensive but renewable resourses, if these resources is used effectively to solve human environmental pollution, food shortages and energy crisis is important significance. 地球上每年大约形成1000亿吨植物有机物,是自然界分布最广、含量最多、价格低廉而又可再生的资源,若能将这些资源有效利用,对解决人类环境污染、粮食短缺和能源危机具有重要意义。
Now research basically formes a relatively complete sequence from early focusing on brand concepts of product level to concern concept and measurement of brand performance now. 品牌早期研究主要集中在产品层次的品牌概念及要素的研究;逐步发展到品牌及绩效的概念和测量,从而基本形成了一条较为完整的研究脉络。
At present, foreign and domestic scholars and agencyes study satisfaction index system and the actual evaluation for a long-term, formes many customer satisfaction index systemes, models and appraisal methods. 目前,国内外众多学者和机构对顾客满意度指标体系的构建和实际测评进行了长期且系统的研究,形成了涉及各行各业的顾客满意度指标体系、模型和测评方法。
At present, the telecommunication industry undergoes the new reform and the reorganization in our country, and formes tripod vertical market competition pattern of the telecommunication operators. The industrial structure has had the tremendous change. 当前,我国电信产业正经历着改革和重组,并形成三家全业务经营的运营商,市场结构发生巨大的变化。
