Then by means of heterocoagulation and encapsulatin , on controlled condition the superfine powders of caco3 and tio2 were coated with different nonaparticles ps . the composite particles with core / shell structure were prepared by heating the composite particles above the glass transition temperature of ps 然后根据异相凝集-包埋法原理对具有不同表面电性的微米级的caco _ 3和tio _ 2进行包埋复合,制得以无机粒子为核,有机粒子为壳层的包覆型有机?无机复合粒子。
On basis of the character of the structure at the stage of construction , the stress balanced method was developed to decided the forces of cables and the stresses of the arch rib sections , which is according to the normal stress controlling conditions on the top and bottom of arch rib section and considering the influence matrix 针对这一受力特点,本文根据拱肋截面上、下缘应力平衡条件及影响矩阵的概念,发展了应力平衡法,用以确定拉索的合理索力,从而使拱助结构受力合理并具有理想的线形。
To study the effects of various chocolate types on brain power , bryan raudenbush and colleagues had volunteers in four groups separately consume 85 grams of milk chocolate ; 85 grams of dark chocolate ; 85 grams of carob ; and nothing the control condition . after a 15 - minute digestive period , participants completed a variety of - based neuropsychological tests designed to assess cognitive performance including memory , attention span , reaction time , and problem solving ability 为了研究不同种类巧克力对于人脑力的影响,布莱恩兰登布什及其他研究人员将参与实验的志愿者分为四组,其中三组分别摄入85克牛奶巧克力85克黑巧克力和85克角豆粉一种可食用的粉状物质,用角豆树的种子和角豆荚磨制而成,常用作巧克力的替代品还有一组不吃任何东西。
In consideration of the soil arch effect between anti - slide piles , a calculation formula for the anti - slide pile spacing was developed , taking the following factors as the controlling conditions - the static equilibrium equation of the frictional resistance and adhesive force between the side of piles and slope soil , which sustains the thrusting force of the landside , and the strength conditions at the medial cross - section and two end sections of soil arch 摘要考虑抗滑桩桩间土拱效应,以桩侧与边坡土体间的摩阻力及黏着力承担滑坡推力的静力平衡条件和土拱跨中与拱脚处截面的强度条件共同控制,建立了抗桩间距的计算公式。
For the high controlled condition for larger nonlinear system , the identification which the classed method is difficult is important . the paper purposed a new associative memory neural network which can replaced system and ready for the request of control . this paper on the basis of fuzzy neural network technique and optimization it ' s parameter can get ideal output 对于大滞后非线性系统控制品质要就比较高的场合,模型辨识是至关重要的,针对大滞后非线性系统难以用经典方法辨识的原因,模拟人脑记忆事物的过程,本文提出了一种新型联想记忆神经网络结构,作为建模工具,以再现被控对象的特征,为控制做好铺垫。
a standard against which other conditions can be compared in a scientific experiment; "the control condition was inappropriate for the conclusions he wished to draw" 同义词:control
