查询词典 random field

This article mainly discussed critical and magnetic properties in the system of mixed spin-1 and spin-1/2 BCM with bond dilution and random crystal field.

中文摘要：混合自旋BCM 的临界行为和磁学性质是本文重点讨论的内容，在本文中我们主要采用了键稀疏和随机晶场作用下混合自旋为1 和1/2 的BC模型，在有效场的框架内计算并讨论了三维简立方系统的临界行为和相关磁学性质。

Methods The inquiry field test and grade random sampling were emplyed on a group of people naturally selected in Shanxi Province.

在陕南、陕北和关中采用分层整群抽样方法，对抽中的村自然人群进行调查，分病种进行病原学检查，并进行统计分析。

SF and collagen films were treated by negative corona discharge, homothermal surface potential decay was tested to detect the charge stability. Result showed circums- tance humidity influenced severely the surface charge stability. There were polar groups on the surface after corona discharge, and hydrogen bonds existed between these groups. On the other hand, ATR-FTIR analysis indicated the conformation transition of SF was induced by strong electric field and a part of random coil conformation was converted into β-sheet structure.

采用自制的负电晕极化装置对丝素、胶原膜进行了表面处理，等温表面电位衰减法测试材料在不同环境中表面电位的变化，发现环境湿度对材料表面电荷稳定性的影响较大；XPS光谱分析表明材料表面有极性基团产生，这些基团之间有可能会形成氢键，同时ATR-FTIR分析表明丝素的构象在强电场的作用下发生了变化，由无规线团转变为β折叠结构。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
