分辨矩阵对角线元素的大小和射线的疏密呈正相关关系。

The results show that there is a linear correlation between magnetic susceptibility and density. Take 1.6 g/cm^3 as a boundary value, the magnetism of high density coal and low density coal was opposite. The diamagnetism property of low density coal weakens and the paramagnetism of high density coal enhances along with the size reduction of fine coal. The magnetic field intensity influences the magnetism of coal.

研究表明：比磁化率同密度间存在线性相关关系，以1.6 g/立方公分为界，高、低密度级煤分别呈顺磁性和逆磁性，且随煤粉粒度的减小，低密度级煤的逆磁性减弱，而高密度级煤的顺磁性增强；磁场强度对煤的磁性有一定影响。

Significant negative correla- tions between the diencephalon 5-HT or 5-HIAA and gastric ulcer index were observed after 45-min peroid of stress, whereas significant positive correlations between them were observed after 180-min of stress.

侧脑室注射5-HT增加应激后下丘脑CRF含量，血浆皮质酮、〓和〓的水平，PCPA则有相反的结果；在应激180分钟时，间脑5-HT和5-HIAA水平分别与血浆皮质酮、〓呈明显的正相关关系。

It was also found that the film of smaller grains corresponded to a smaller lattice constant of the garnet structure, which implied that fewer Bi〓 ions substituted into the dodecahedral sites in the garnet, due to the fact that the smaller grains resulted in more grain boundaries, thus leading to more serious Bi segregation in the grain boundaries.

分析表明，细小的晶粒意味着薄膜中含有更多的晶界，这样将导致Bi组分在晶界上的偏析较显著，而进入石榴石结构中氧十二面体间隙的Bi〓较少，对于Bi，Al∶DyIG来说，石榴石相晶格常数与{Bi〓}〓呈正相关关系，由此可以解释具有细小晶粒的薄膜对应较小的石榴石相晶格常数。
