In Chapter Two, some methods such as electron microscope, DNA ending label and MTT measurement were used to studied the changes of apoptosis, necroses and cell vigour of leukaemia K562 cell trunk and HL-60 cell trunk irradiated with millimeter wave. Different effects of millimeter wave to leukaemia cell trunks and human marrow cells were observed clearly. Human marrow cells were not so sensitive to millimeter wave radiation as leukaemia cells.

第二章，利用电镜技术、DNA末端标记、MTT活力测定等方法，研究了毫米波对红白血病K562细胞株、人类急性早幼粒白血病细胞株HL-60及正常人骨髓单核细胞的细胞超微结构、细胞凋亡、细胞活力的影响，结果发现毫米波辐射对正常人骨髓细胞及白血病细胞的影响明显不同，正常人骨髓细胞所受影响较小，特别是功率密度小的毫米波对其无影响；而白血病细胞受辐射后发生显著的凋亡或坏死，细胞活力显著下降，该效应具有明显的功率窗和时间窗。

In this thesis, the phase diagram of Zn-Al binary system on 10~69.5 w% was reinvestigated by using differential scanning calorimeter, X-ray diffraction and pushrod dilatometer. The process of isothermal transformation during the aging of high-Aluminum-Zinc-based alloy was studied by using differential scanning calorimetry, and the aging behavior of the alloy was analyzed at the aspect of thermal analysis kinetics. The change of microstructure which the alloy was being heated was observed on high-temperature metallurgical microscope. The microstructure and wear-friction properties were compared among the alloys treated with several different heat treatment processes, and a model for heat treatment processes was proposed based on artificial neural network,so as to predict the relationship between friction coefficient and parameters of aging treatment such as aging temperature and time.
