This paper provides the change of base resistance in Si-UJT which were irradiated by 60Co γ-ray. Through multipoint measurement and real-time monitoring, the result shows that the base resistance decreased immediately and then increased slowly.

本文针对硅材料和硅基器件辐照损伤机理间的矛盾问题，采用对单结晶体管基区电阻实时监测的方法，得到单结晶体管基区电阻值随γ射线辐照剂量的增加先减小后增大的规律。

Results show a total of over 30 16S rDNAV3 fragments were obtained from the soil samples, and DGGE analysis of the 16S rDNAV3 fragments revealed little variation in fingerprint, but it was found that each had its own characteristic strip.

结果表明，3块林地土壤165 rDNAV3区片段高达30条以上，不同林分下土壤165 rDNAV3区片段的DGGE带谱差异不大，但各有特征条带。

The results show: the most sensitive Chinese area to acid deposition is Podzolic soil area, then follow Latosol, Dark brown forest soil and Black soil areas; Ferraisol and Yellow-brown earth area in southern China can buffer about 0.8-1. 6 g Sm〓yr〓 sulfur deposition; the least sensitive areas to acid deposition are mainly Xerosol area in northwest China, Alpine soil area in the Qingzang Plateau, and Dark loessial soil and Chernozem areas; the main reason for lower critical load in northeastern areas and higher critical load in Ferralsol and Yellow-brown earth areas in China can be attributed to the obvious difference in temperature, humidity and soil properties.

研究表明：我国土壤对酸沉降最敏感的区域是漂灰土带，其次是砖红壤土区、暗棕壤带和黑土区，南部富铝土区域大致可接受O.8-1.6 g Sm〓yr〓的硫沉降，对酸沉降最不敏感的区域主要集中在西北干旱土和青藏高原的高山土区域以及黑垆土和黑钙土带；导致我国东北地区酸沉降临界负荷偏低和富铝土区域酸沉降临界负荷偏高的重要原因，是这些地区的气温、湿度和土壤质地存在显著差异。

Then the intracellular calcium concentration of neurons was measured by laser confocal scanning microscope , represented by the mean intracellular fluorescent intensity. On the ice, the cerebral cortical tissue at the infarction margin of the section after optic chiasm was rapidly dissociated about 100mg, then made into brain homogenate in low temperature. The high performance liquid chromatography was used to determine the Glu, Asp and Gly contents in homogenized brain tissue.

视交叉平面用2％TTC染色，用图像处理软件计算出脑梗死面积占该片脑组织面积的百分比；取视交叉前平面梗死边缘区皮层组织约100mg，用酶消化法制作神经细胞悬液，用激光扫描共聚焦显微镜检测皮层神经元细胞内游离钙离子浓渡，以细胞平均的荧光强度代表细胞内钙浓度；冰上迅速分离视交叉后梗死边缘区皮层组织约100mg，于低温下制作脑组织匀浆，用高效液相色谱法测定皮层匀浆中谷氨酸、天门冬氨酸、甘氨酸的含量。

Methods Two hundred and seven patients with newly diagnosed and treated benign sellar region mass lesions that were touching or compressing the optic chiasma and/or optic tract were Included. The mass lesions included 116 cases of pituitary adenoma 52 cases of craniopharyngioma, 18 cases of meningioma, 14 cases of cystic lession and 7 cases of pituitary abscess. The MR features, positive ratio, relationship of OTE sign to tumor size or pre-operative visual signs were retrospectively analyzed.

207例初次确诊和手术病理证实的鞍区良性占位病变患者，肿瘤均接触或压迫视交叉和/或视束，其中垂体腺瘤116例、颅咽管瘤52例、鞍区脑膜瘤18例、囊肿性病变14例、垂体脓肿7例，回顾性分析MR上OTE征的影像学特点、阳性率、与肿瘤大小和术前视觉功能障碍的关系。

Results By using optical microscope,the neurocytes of hippocampus in experimental group were observed to denaturalize,tumefy,destroy and disappear.And under electron microscope,the karyon was irregular,nucleoles deviated,chondriosome tumefied,crista collapsed,membrane was damaged,substance cavitated.Such changes were more evident with the increased paroxysm of epilepsy,the parameters between control group and operation group had no difference（P＞0.01）.But make a monofactorial variance analysis among cells' number,area,circumference and integral optical density in different groups,it showed that there were significant differences between optional two groups（P.01;at the same time,the more serious injury in hippocampus,the more powerful GFAP immunoreaction was.

结果： 实验组海马区光镜下可见神经细胞变性、肿胀、坏死及神经细胞脱失改变，电镜可见细胞核形态不规则、有切迹、核仁偏位、线粒体肿大、嵴断裂、膜破损和基质空化等改变，随癫痫发作次数增加上述改变越明显，对照组与手术对照组比较，各参数差异无显著性（P＞0.05），将不同组别大鼠细胞数、面积、周长、积分光密度分别作单因素方差分析，不同组别间均差异有显著性（P.01），同时观察到海马区GFAP免疫反应阳性的胶质细胞随海马损伤的加重而GFAP免疫反应增强。

Methods 18 rabbits were used to observe the osteogenesis of percutaneous autogenous bone marrow into cicatrix of bone defect.A 1cm bone defect model was made in each side of the radius.
