In the numerous extension patterns, the government leading extension pattern is the strongest, quicker, and the extension area is larger, but the extension system should be further strengthened, and the policy supports should be given by the government. The extension pattern with the research institutes as the main body is strict and scientific, and is welcomed by the peasants, but the extension strength is weak. The extension pattern with the companies as the main body has the advantage in the extension area, and is a new pattern, but the service consciousness of the agricultural fertilization should be strengthened. The extension pattern with the supply and marketing cooperative as the main body has the advantage of retailing fertilizers, but the technical training to the vocational staff should be strengthened. In the extension pattern with the chain radiation as the main body, the activity of the peasants is higher.

研究表明，在众多的推广模式中，政府主导型推广模式的推广力度最大，推广速度较快，推广面积也较大，但是推广体系应进一步强化，政府应给予政策上支持；以科研单位为主体的推广模式严谨、科学，受到农民的欢迎，但推广力度小；以公司为主体的推广模式在推广面积上有一定优势，是一支新生力量，但应强化农化服务意识；以供销社为主体的推广模式具有分销肥料的优势，但应对该系统的业务人员加强技术培训；以连锁辐射为主体的推广模式中，农民积极性高；以科研+公司+推广+农户为主体的(来源：ABC论文5b网www.abclunwen.com)推广模式在推广面积、农民的积极性均有一定优势，它能把几大部门的利益集中在一起，取长补短，以共同促进平衡施肥的发展。

At postoperative 24 hours, neurological defects were scored in five grades [0 score represent no neural impairments; 1 score: the left posterior limbs displayed decreased muscular tension and attenuated contraction reflex; 2 scores: the left posterior limbs were paralyzed, displaying obvious abduction; 3 scores: rabbit displayed obvious adductive drag with body leant to the opposite side; 4 scores: unable to walk and unconsciousness], rabbits were put to death at postoperative 48 hours, infarctional area and volume were determined and pathological changes was also observed.

术后48 h处死兔，测量梗死灶面积、体积，并制作病理切片观察损伤程度。主要观察指标：兔肢体功能状态，脑梗死灶面积和体积，病理损伤程度。结果：59只兔成功建立起梗死灶，模型成功率为98％。①神经功能缺失评分：56只兔为1或2分，有3只兔达到3分。②梗死灶平均面积为(0.465±0.012)cm2，平均体积为(0.268±0.009)cm3。

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。

The indexes that could significantly discriminate the two groups was: callosal atrophy,ventricle-to-brain ratio,WML area,left cortical infarct area,left parietal infarct area,total cortical infarct area.
