A systematic method has been established for primary cultivating of cortical neurons. Observations indicated that the cortical neurons were affixed to the culture after 4h, and the nerve cells had 1-2 small processes. The Nissl's staining results show that the purity(≥92%) of the cortical neurons rose apparently on days 3 and 6 post-beginning of culturing with Ara-C inhibition. The MTT experiment show that the viability of the neurons was the highest,and they are oval,araneiform and pyramidal and formed an integrated neural network on day 6 post-beginning of culturing.

光学显微镜观察结果表明，培养至第4h绝大多数神经元已贴壁生长，胞体上可见1~2个细小突起；培养至第3d、第6d时，Nissl's 染色结果显示，加Ara-C能显著提高神经元纯度（≥92%）；MTT结合形态学观察结果表明，神经元培养至第6d时活性最强，细胞呈卵圆形、蜘蛛状、锥体状等多种形态，细胞胞体饱满，光晕明显，神经网络形成完整。

It expanded to 106119ha in 1973, descented to 99167ha in 1987, backed up to 112440ha, and attained the max value in history—123170ha in 1998 and descent to 109934ha again in 2001. GIS overlaying analysis shows that, the spatial change of Minqin Oasis had the different characteristics in different stage in the last 50 years: at the end of 50's to the beginning of 70%, oasis expandation Was performed by extension of origin oasis; the atrophia of oasis from the beginning from 70's to the 80's was performed by increasing of non-oasis spot pieces of inner part for oasis; the main performance of keeping on expanding of oasis from late 80's to late 90's is outside extension of Baqu oasis near the upper stream, with increased oasis area in interior of hungriness and increased area of non-cultivation in Huqu oasis in the north. From 1998 to 2001, opening up wideness in interior of hungriness continued, but hnngrinessization of oasis became worse. The oases in the Minqin Basin developed from small to large and back to small in terms of area changes, and from south to north then to south in terms of spatial changes.

绿洲分布图的GIS叠加覆盖分析表明，近50年来民勤绿洲的空间变化在不同阶段有不同的特征：50年代末至70年代初，绿洲扩展主要表现为已有绿洲的外延式扩大；70年代初至80年代后期的绿洲萎缩，主要表现为绿洲内部非绿洲斑块增加；80年代后期至90年代后期的持续扩展，主要表现为靠近上游的坝区绿洲向外围扩展和荒漠腹地绿洲面积的增加，而北部湖区绿洲弃耕面积不断扩大；98年至2001年，绿洲荒漠腹地的开荒还在继续，但湖区的绿洲荒漠化还在进一步加剧。50年来民勤绿洲的发展总体上经历了一个面积由小到大再到小，空间位置上从南而北再向南的迁移过程。

This dissertation holds that the power of the state in the relationship should betrace back to the beginning of liberation.The new regime built grass-roots level of"authoritarian control"at the beginning through reconstructing neighborhood inShanghai,the strong power of the state continued after the transition,from"authoritarian control"to"institution to absorb",what\'s changed is the specific form.

本文认为，国家相对于城市邻里的这种强势关系，源自于解放之初新生政权通过改造邻里空间在城市基层构建的&威权控制&，国家的强势关系一直延续到社会转型之后，从&威权控制&到&体制吸纳&，只是其形式发生了变化。

Pattern of change of time of two ground time is roughly same also, sichuan at the beginning of time of ~60 of 50 time end warmer, end of time of the ~90 at the beginning of 60 time slants cold, air temperature is apparently elevatory since 90 time end and strength is greater; Chongqing end of time of ~60 of 50 time end is warmer, air temperature change and Sichuan province are basic and identical after 70 time.

两地年代际变化规律也大致相同，四川50年代末~60年代初较暖，60年代初~90年代末偏冷，90年代末以来气温明显升高且强度较大；重庆50年代末~60年代末较暖，70年代之后气温变化和四川省基本相同。
