本实验在未用任何免疫抑制剂的情况下，肝细胞胸腺内注入后1周、2周，显微镜下见植入胸腺内的肝细胞已生长出不规则的肝索及肝窦样结构。3周时的胸腺内植入的肝细胞仍存活，但空泡变性明显。

M. The design of a time resolved flat-response x-ray imaging system has been accomplished, with the combination of Wolter x-ray microscope, x-ray streak camera, and a compound filter.

利用Wolter X光显微镜收光立体角大，而且在收光立体角截面上容易划分成不同区域的特点，用X条纹相机作为图象记录系统，完成了一套在0.1～1.5 keV能区对X光能量平响应的高时空分辨测量系统的设计。

In order to elucidate the effect of the texture, structure and particle size of aggregate on determining its ASR reactivity, the texture, structure and ASR features of zeolitic pearlite and siliceous gravel were examined by optical microscope, XRD and SEM/EDS. It has been found that in addition to the type and amount of reactive constituents in aggregate, the physical structure has also strong influences on the process and expansion behavior of ASR, and the influences of physical structure may be various with particle size of aggregate.

为进一步研究集料结构构造和集料尺寸对鉴定集料ASR活性的影响，用光学显微镜、XRD和SEM／EDS等方法研究了集料的岩石学、矿物学特征及其ASR反应特征，发现除集料中活性组分的类型和数量外，集料的物理构造特征对ASR过程和膨胀行为有显著影响，而且集料的尺寸不同，物理构造的影响程度有差异。

The micro-morphology of the initiation zone of SCC of Ti-5A1-2.5Sn alloy in 3.5% NaCl solution has been inspected by OM and SEM.A study of the SCC crack's details by OM,TEM,X-ray diffractometer and ion microanaly- zer has also been made.

本文用金相显微镜和扫描电镜对 Ti-5Al-2.5Sn 合金在近中性3.5%NaCl 水溶液中 SCC 裂纹形核带的微观形貌进行了观察。

Such changes in shape were recorded with the light microscope over 80 years ago.

在80年以前已用光学显微镜记录了这样的形状变化。

The difference between warm compaction and cold compaction of pure iron powders without admixed lubricant was compared with an Instron thermal simulater.

在Instron热模拟机上对不添加润滑剂的纯铁粉进行温压和冷压的实验比较，用扫描电镜、X射线衍射和金相显微镜对粉末及其压坯进行分析，并对纯铁粉的温压致密化机理进行探讨。

The cochleae of animals were dissected. propidium iodide, a dna intercalating fluorescent probe, was used to trace the morphological changes in ohc nuclei. f-actin staining was used to determine missing ohcs. the single strand dna in apoptotic ohcs of guinea pigs and mice, and apoptosis inducing factor and endonuclease g in ohcs of guinea pigs were examined by immunofluorescence method.

分离解剖耳蜗后，用碘化丙啶染色细胞核、pholloidin染色f-actin，免疫荧光抗体分别染色单链dna、核酸内切酶g和凋亡诱导因子（apoptosis inducing factors， aif），制备耳蜗铺片，激光共聚焦显微镜下观察凋亡和坏死毛细胞内的荧光信号变化。
