Nerve stem cell can be differentiation into astroblast, oligodendrocyte and nerve cell induced by factors.

神经干细胞的增殖分化可受各种因素的影响，目前已知，许多细胞因子，生长因子，营养因子以及细胞外环境等因素的作用，可诱导神经干细胞向不同的终末细胞分化，若能在体外分离培养神经干细胞并在促分化因子的作用下，诱导神经干细胞向某一特定方向分化，将为干细胞的分化机制提供有力的实验依据。

The results showed that glucose and fructose are primary soluble sugars from night to 10: 00 a.m. in mature leaves, but during 13: 00 - 16: 00 p.m., stachyose becomes the most abundant oligosaccharide, this diurnal change is mostly due to the tempestuous fluctuation of stachyose concentration in mature leaves. During photoassimilate transportation, the p rimary soluble sugar in phloem sap is stachyose. When transportation is finished, sucrose becomes the main sugar in phloem sap. Cucumber leavesmay store photoassimilate in the forms of starch, glucose, fructose, stachyose and sucrose at night. The concentrations of glucose, fructose and stachyose in phloem sap are much lower than in leaves at that time. There may be some unique mechanisms modulating source-sink translocation by which soluble sugars in leaveswere prevented from loading into the phloem further during night.

结果表明夜间至上午10： 00，葡萄糖和果糖是叶片中主要的可溶性糖，而下午13： 00至16： 00，水苏糖成为成熟叶片中含量最高的可溶性糖，这种变化主要由叶片中水苏糖含量剧烈的昼夜变化引起；当黄瓜同化物从源叶向外运输时，韧皮部汁液中的可溶性糖以水苏糖为主，运输完毕后则以蔗糖为主；黄瓜成熟叶片在夜间以淀粉、葡萄糖、果糖、水苏糖、蔗糖等各种形式贮藏尚未运出的同化物，而此时韧皮部汁液中葡萄糖、果糖、水苏糖的含量极低，可能有特定的源库调节机制阻止叶片中的可溶性糖在夜间进一步向韧皮部中装载。

The sac structure projected through the pollen aperture possesses the typical nature of transfer cell, i. e complex lybrinthian wall ingrowth and abundant mitochondria, RER, dicotysomes and ribosomes under the wall. Its outer surface is closely related to the tapetal protoplast. The accumulation of storaged material in pollen start at the area near the apertures. Above restults indicate the pollen apertures may be the"door"from where nutrition flows into pollen in P. hortorum.

绒毡层物质向花粉粒的短途运输明显的表现在花粉的萌发孔区，一方面形成向外突起的囊腔，另一方面在这里具有发达的壁迷宫，而且迷宫下具丰富的线粒体，RER和高尔基体等细胞器，此外花粉内贮藏物的大量积累首先从萌发孔附近开始以及萌发孔处与绒毡层有紧密接触都说明天竺葵花粉萌发孔可能是物质进入花粉的&门户&。

Based on a computing model of floor heating residences, indoor thermal environment and heat distribution under the effect of heat charge/discharge, operation control and solar radiation has been concluded. Concept and formula of equivalent heat supply has been put forward which indicate that actual heat supply will be equal to the sum of design heat supply and equivalent heat supply. Recommend coefficient has been given taken Dalian as an example. Computed according to the new method, design heat supply can be reduced to 37% in cloudy day and 43.3% in sunny day, energy saving effect is very obvious. In Tromb wall solar house, effect of concrete wall on indoor temperature swing and attenuation of temperature wave is very obvious. While the outdoor air-temperature swing exceeds 10℃, indoor air-temperature swing belows 3℃. In the experiment, maximal difference in temperature between inner surface and outer surface of the 300mm wall exceeded 10℃. Heat storage and collector efficiency varies adversely according to solar radiation. Factors such as thickness, material, absorptance of the wall and permeation of the glass cover all have big influence on heat storage and collector efficiency. There exsisted an optimal thickness of the wall, which can make the best of heat storage and collector efficiency. Most of the heat stored in conventional Trombe wall during the daytime has been lost to the outside at night without heat preservation. Heat preservation on the outside surface of the wall has effectively improved heat release performance of the wall at night, heat supply to the room has increased too.

通过建立的地板采暖系统动态热性能分析模型，得出了在蓄放热特性、运行方式和太阳辐射等因素耦合作用下的室内热环境及热量分配比例，提出了等效供热量的概念及计算公式，指出实际所需供热量应等于设计供热量加上等效供热量，并以大连为例，给出了等效供热量的修正系数，以新方法计算，阴天可减少设计供热量37％，晴天最大可以减少设计供热量43.3％，节能效果显著；集热蓄热墙式太阳房中，混凝土蓄热墙的室温均一化效果和对温度波的削减作用非常明显，当室外温度波动最大幅度超过10℃时，室温波幅不超过3℃，实验中300mm厚墙体内外表面温差超过10℃；墙体蓄热效率与集热效率随太阳辐射照度的变化呈相反的变化趋势；墙体厚度、材料、表面吸收率以及盖板透过率等因素对集热和蓄热效率均有较大的影响，存在一个最佳的墙体厚度值，使得墙体集热和蓄热综合性能最优；传统的蓄热墙夜间没有外保温，辐射散热损失很大，研究表明墙体外保温方式明显改善了蓄热墙夜间的散热性能，增加了向室内的供热量。

Whereas osteoporosis is unassociated with bone pain, osteomalacia has been associated with isolated or generalized bone pain.39,40 The cause is thought to be hydration of the demineralized gelatin matrix beneath the periosteum; the hydrated matrix pushes outward on the periosteum, causing throbbing, aching pain.7 Osteomalacia can often be diagnosed by using moderate force to press the thumb on the sternum or anterior tibia, which can elicit bone pain.7,40 One study showed that 93% of persons 10 to 65 years of age who were admitted to a hospital emergency department with muscle aches and bone pain and who had a wide ariety of diagnoses, including fibromyalgia, chronic fatigue syndrome, and depression, were deficient in itamin D.41

然而，骨质疏松症与骨痛无关联，而软骨病则与局部性或全身性骨痛有关。其原因被认为是骨膜下已去矿质化的胶原基质上发生的水合反应，水合的胶原基质在骨膜上向外扩张，引起阵痛。软骨病可通过以拇指适度挤压胸骨和胫骨前方以引起骨痛感。一项研究显示10岁到65岁中有93%的人向医院急诊室承认有肌肉疼痛和骨痛症状，他们还有一些其他症状包括纤维肌痛、慢性疲劳综合征、抑郁等，该研究显示他们都缺乏维生素D。本人已认领该文第9、10两部分，48小时后若未提交译文，请其他战友自由认领。本人已认领该文11、12部分编译，48小时后若未提交译文，请其他战友自由认领。本人认领第十三部分，48小时内交稿请战友纠错！

That night we sat in sir henry's room and waited.at about three o'clock in the morning we heard the sound of footsteps outside the bedroom.we looked out and saw barrymore.we followed him as quietly as we could.he went into the same room as before.we reached the door and looked in.there was barrymore,with the light in his hand,looking out across the moor,exactly as i had seen him on the night before.

那天晚上我们坐在亨利爵士的房间里等着。大约在凌晨3点钟时，我们听到了卧室外面的脚步声。我们向外望去，看到了白瑞摩。我们尽量无声无息地跟踪着他。他同前一次一样，又到了那个房间里。我们来到房门旁边向里望去。白瑞摩手里拿着蜡烛，正望着窗外的沼地。这和我前一天夜里看到的情景一模一样。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
