In the paper the preparation process is expatiated . on the base of available information the controlling conditions are determined through a lot of trial experiments , and are optimized . by which , the coming experiments are performed 文章对制备过程进行了阐述,通过大量的摸索性试验确定了制备过程的控制条件,并对这些条件进行了正交优化,得出优化结果并运用到其后的实验当中。
Interferences to experimental results by effects of coal inhomogeneity , particle size and volatile release on char properties have been greatly reduced by special methods . pyrolysis chars have been obtained under various well - controlled conditions close to those of cfb combustion 实验研究排除了煤质不均匀性、粒径和挥发分析出的干扰,同时又处于实际cfb燃烧条件范围内,可以严格控制热解焦碳制备条件。
The first chapter is introduction . a lot of possible signatures of qgp formation predicted by theorists are introduced in this part . the ultra - high energy heavy - ion experiments are the main ways to study qgp phase transition at the controlled condition 论文的第一章为引言部分,主要介绍了qgd相变与夸克?胶子等离子体的特性,高能核?核碰撞的时空图像和相变条件、以及理论上预言的qgp存在的一些可能的信号。
First , based on the arisen conditions of hopf bifurcation of the delay system and the corresponding handling methods , we propose an analytic method for achieving the controlling conditions when a low - dimensional chaos system is controlled by dfc , and obtain the function relation of controlling parameters 基于数学上分析延迟系统产生hopf分支的条件及处理方法,针对用dfc法控制低维混沌系统的情况,我们提出了确定其控制条件的一般解析方法。
3 ) different expectant targets determine different methods of determining reasonable cable force . only making using of a certain method inevitably has disadvantage and shortcoming . reasonable results can be attained through some methods because controlling conditions are not adopted reasonably 3 )希望的成桥目标不同,确定斜拉桥成桥状态下合理索力的方法会有所不同,单一使用某种方法确定斜拉桥的成桥状态下的合理索力,不可避免地存在缺点和不足。
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,
