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。
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
