第三

Firstly, the establishment of model requires sophisticated neurointerventional techniques and costly interventional materials(sacculus, minikin circlip ring, endovascular electrocoagulation), it not only consumed time but also increased the resesrch expense ; Secondly, although the Massoud model is the first successful model that contain the nidus, but it is far from mimicking the high-flow fistulae frequently observed in a brain AVM; Thirdly, the rapid spontaneous thrombosis result in fistula occlusion in a short time;Fouthly, the model's natural course and the long–term patency of fistula are unclear;Currently the model is only used for the short-term research.

但Massoud模型目前存在以下主要缺点：第一，模型的建立需要复杂的神经介入技术和昂贵的介入材料(球囊、微弹簧圈、血管内电凝等)，操作费时，又大大增加了研究费用；第二，Massoud模型虽然首次具备了畸形血管团，但它远不是我们临床上常见的含有高流量动静脉瘘的脑AVM；第三，颈动静脉吻合口自发性血栓形成进而导致引流静脉闭塞的机率很高；第四，Massoud模型的长期自然过程和动静脉吻合口的长期通畅性尚不清楚，目前仅仅作为急性期模型。

Third, rail-to-rail AMPLIFIER OUTPUT stages exhibit load-dependent gain which affects AMPLIFIER open-loop gain, and hence closed-loop gain accuracy.

第三，轨到轨放大器的输出状态表现出影响开环增益从而影响闭环增益精度的负载增益效应。

Secondly, before reseeding white clove and cocksfoot firing disposal should be done to the main weed and the dead substance on pasture in June.

18.1 提高牧草生长速率的有效优化调控技术是：第一，7～10月牧草生长旺季适当增加载畜量；第二，6月份对草地主要杂草和死物质进行火烧处理，然后补播白三叶和鸭茅；第三，6月初雨期撒施钙镁磷肥、尿素；第四，实施划区围栏，有效控制放牧面积；第五，每年5—10月刈割杂草；第六，适度减少人工草地中非洲狗尾草和狼尾草的比例或予以清除；第七，在与常年风向垂直的地段建植防护林带。

Third, the majority of its real estate as collateral.

第三，它的大部分房地产作为抵押。

Thirdly, for those who tied down with an unfulfilling job, a career change can be translated into more diverse experience with new managerial styles, better collegiality and more financial reward.

The study contains five parts excluding introduction. First, it reviews the literature. Secondly, it analyzes the organization of university-bureaucracy, collegium, political system, symbolic system and cybernetic system. Thirdly, it analyzes what is the visional president. Fourthly, we think about the dilemma- doing the right things and doing the things right, educational idea and the practice of policies, changing the organizational culture and developing step by step, administrative men and economic men.
