查询词典 distribution difference

Because the time series generated from finite difference equation with chaos may also possess exponential distribution of probability density. Additionally, irregular dynamics has ever been attributed to the presence of stochastic noise in many systems, but actually it may result from chaotic process in deterministic system.

近年来对非线性动力系统的深入研究发现：观察到某一过程具有指数型概率密度事件分布并不足以确定它就是泊松过程，由具有混沌行为的有限差分方程所产生的时间序列也可具有指数型概率密度分布；在许多系统中，过去归因于随机噪声的不规则动力学特性，实际上很有可能是由确定性系统中的混沌过程所致。

The development and utilization of digitized information resources play crucial role in providing support for petrochemical technological innovation. In the web circumstances, more and more digitized petrochemical information resources become an important content that of the special library.

The distribution of temperature stress was calculated by finite element analysis. The results showed when the surface temperature of concrete was higher than 110℃, the temperature stress was more than 4 MPa without regard to the creep. This might be lead to the damage of the surface of concrete. At the same time, a lot of microstructure analysiss such as XRD, SEM, IR, HSA etc. were done to analysis the difference of the component and microstructre of concrete before and after corrosion. The results indicated that the decomposion of CSH gel and calcium hydroxide and the creation of dilatability calcium oxide were the internal reason of the deterioration of concrete in the corrosion form of high heat.

该文通过有限元方法计算了由于温度而产生的结构应力分布，计算结果表明当混凝土表面温度超过110℃时，如不考虑徐变时表层混凝土受到的温度应力将超过4MPa，这使得表层混凝土很容易因温度应力而破坏；同时通过X射线衍射分析、扫描电子显微分析和混凝土孔结构分析等多种微观结构测试手段，分析了混凝土受热前后的宏观性能以及微观组成和结构的变化，指出混凝土原水化产物如水化硅酸钙凝胶和氢氧化钙的分解以及膨胀性产物氧化钙的产生是高热腐蚀形式下混凝土破坏的内在原因。

4土壤水分沿坡面呈"波浪形"分布是坡面径流的波动性、上方来水的沿程入渗、侧向沿坡向下流以及坡面各处入渗性能和蒸发蒸腾作用的差异等综合作用的结果。

Through similar simulation test of block top-coal drawing, the influence of coal block size and block position in top coal on the recovery ratio and drawing manner is studied. It is found that the drawing manner has the different adaptation to the top coal which has different block distribution. The caving capacity is mainly decided by the block size. The top-coal which has layer difference of block with the same size has different recovery ratio. It is shown, that, to the given top-coal blocks, the recovery ratio of uniformly mixed blocks is maximal in the manner of drawing at interval of one support.

研究表明，顶煤块体大小是影响顶煤回收效果的主要因素，在顶煤块径一定的条件下，块体层位分布不同是造成顶煤回收率差异的主要原因，研究表明各级块度均匀混合时顶煤回收效果最好，块度从下向上增大分布次之，大块为中位顶煤时回收效果最差；各种放煤方式的适应性不同，各级块度均匀混合的顶煤适合用间隔放煤；块度从下向上增大适合用顺序放煤；大块在顶煤中位分布时，中硬煤以下适合用间隔放煤，硬煤应采用顺序放煤方式。
