TEM analysis exhibits that the predominant dislocation configuration of HCF specimens is parallel dislocation walls.

疲劳变形亚结构的TEM分析表明：纯锆典型的位错组态是平行位错墙。

Results show that a small amount of Mg and Zr can improve neither HCF properties nor fatigue notch sensitivity.

结果表明，微量元素Mg、Zr对提高疲劳性能不显著，也不能改善疲劳缺口敏感性。

The risk factors for HCH were studied by means of both single factor analysis and multifactor analysis.

采用单因素分析与多因素分析HCH的危险因素。

Therefore, prohibition of HCH by China has led to positive environmental impact.

因此，中国禁止HCH的使用对环境的改善取得显著的成效。

The following experimental conditions for assaying the sensitivity and stability of IL 1 activity, were observed: ( 1) thymocytes of C3H/ HcJ strain of mice were found to be more sensitive to IL 1 activity;

为提高检测IL-1活性的敏感性和稳定性，应注意：①用于取胸腺细胞的鼠种以C3H/HeJ为好；

The data of the experiments indicate that doped additives have obvious effect in preparation of high remanent flux density Br, high remanent flux density Br and high coercivity Hcj, and high coercivity Hcj materials.

试验数据说明，这种添加剂对于制造高Br，高Br、高H cj和高H cj材料有明显的效果。

Above 2h, the further increase of time has little effect on Hcj.

大于2h后，回火时间的进一步增加对Hcj影响很小；

Objective To explore the changes of hemopoietic cell kinase ( HCK) gene mRNA expression in human auricular myocardium of atrial septal defect ( ASD) and analyze the relationship between abnormally expression of HCK gene and the pathophysiology of ASD.
