The surface hardness variations of some kinds of polymers were compared and the influence factors such as ion species , particle energy and dose were analyzed 通过比较几种不同类型的聚合物材料在注入前后表面硬度的变化,分析注入离子种类、注入能量、注入剂量等工艺参数对聚合物的影响。
The hardness and thickness of coal seam play a great role in the vertical distribution of stress in coal and the occurrence of rock bunt under the condition of hard roof and hard floor 在“两硬”条件下,煤层厚度与硬度的变化对煤体中的应力分布有着很大的影响,从而对煤岩体系统中冲击矿压的发生有着很大的影响。
Our research used this laser system and its precise measurement software to make a all - round study on the relationship of zona pellucida thickness / hardness variation of human embryos and clinical pregnancy outcome following in vitro fertilization treatment and the application of laser thinning in assisted hatching . the purpose of this study was to try to provide the basic rationale for assisted hatching and an alternative assisted hatching method 本研究即为应用这种激光系统及其精确的测量软件,对zpt 、 zptv与妊娠结局的关系、体外培养胚胎透明带硬度的变化及激光薄化透明带进行辅助孵出的临床应用进行综合研究探讨,旨在为辅助孵出的病人选择、方法选择提供基础与临床理论依据。
