Through analysis on the present technologies, this study discovered that low-temperature condensation is a relatively matured method with high cost and highly-consumed energy; the other methods like adsorption, absorption and membrane osmose process are differently characterized by many features hut have not been applied in industrial use for many reasons, Along with many new materials and techniques, helium abstraction technologies from natural gas have been innovated like the adsorption arid membrane osmose process have developed fast and co-production and combined technologies have a good application prospect, which provide new thoughts for the development of helium abstraction technologies from natural gas.

通过对目前提氦技术的分析介绍，低温冷凝法较为成熟，但能耗、成本较高；吸附法、吸收法和膜渗透法等其他提氦技术各其特点，但目前限于适用条件尚不能规模化工业应用，随着新材料、新技术的发展，天然气提氦技术不断改进创新，吸附法、膜渗透法等提氦工艺发展迅速，联产法、联合法工艺有着良好的应用前景，这些都为促进天然气提氦技术的发展提供了新的思路。

In our country, the current research on 5S, which is basically in the stage of summing up practice and experience, has not conducted any works about the fundamental research on 5S.The most works are the summary of steps and skills of 5S which is carried out, however, have not formed the system. They can not analyze 5S from the point of sociological and psychology, especially not from angle of humanity supposition and organization behavior. Therefore, they lack rationale base, appearing palely and weakly.

我国当前对5S的理论研究基本上处于实践经验的总结阶段，并没有任何对5S进行理论研究的著作，更多的是对5S推行的步骤、技巧等的总结，并没有形成体系，没有从社会学、心理学的角度进行深入的剖析，特别是没有从人性假设、组织行为等角度去挖掘，使之变的缺乏理论基础，显得苍白无力，仅仅就实践谈实践，还没有真正提升到理论水平的高度。

Night of my childhood years spent in the great disorder, and in the countryside, the stars have not yet a full-time, every family households to avoid the closing doors, and the house cottonseed oil teeny little flashing lights are too bright not too long, Some can not afford even the cotton oil lamp has also raised the poor households, with sorghum wearing castor bean pole of the crust, light on behalf of the lamps, and some farmers simply will not light up the dark grass fed to livestock feed, dark sleep.

我的童年之夜是在荒乱岁月里度过的，在乡村，星星尚未出全的时候，家家就掩门避户了，屋里的棉油蝇头小灯也不敢亮得时间太长，有些连棉油灯也点不起的贫穷户，用高粱杆的硬皮穿起蓖麻子，点亮代灯用，还有一些农家干脆就不点灯，摸黑给牲口喂草喂料，摸黑睡觉。

Results:(1)NSCs form typical neurospheres under adequate concentration in vitro, which are immunoreactive to Vimentin. Typically and terminally differentiated mature neural cells could not be found without the stimulus of mitogen or only under NSCs self-regulation and self-induction;(2)NSCs derived from hippocampus maintain the character of stem cells much longer with better biological behavior; NSCs passed to the 2-3 passage are the best to graft since they have not differentiated;(3)NSCs cultured in vitro could self-regulate and differentiate into neurospheres and progenitors positively immunoreactive to specific antibodies representing neurons, astrocytes, oligodendrocytes and Schwann cells;(4)There are widespread synaptic contacts between various kinds of descendent clones and cells;(5)Neurospheres could be formed without the stimulus of mitogen when NSCs and OECs are cocultured. Many neurospheres and cells immunoreactive to Vimentin, GFAP, MAP2, 02, p75NGFR, GFAP, S-100, Synaptosis, Vimentin, Tau (Tau is only positive in cocultureof HNSCs+HOECs) could be found;(6)The supernatant fluid triturated from adult rat spinal cord stimulates NSCs to differentiate into neurons, but do not terminally differentiate;(7)Fibroblasts and O4 oligodendrocytes are not supported to grow under this culture medium.Part II: Isolation, culture and identification of rat and human olfactory ensheathing cellsOlfactory ensheathing cells/glials are the most powerful cells to enable the regeneration of axons in the central nervous system.

结果表明：①在适宜的浓度体外培养条件下，NSCs能形成典型的神经干细胞克隆球，Vimentin免疫荧光染色阳性，单靠丝裂原刺激或NSCs自我调节和分化诱导，不会产生典型的终末分化的成熟神经细胞；②海马源性的NSCs维持干细胞特性的时间更长，生物学特性更优；③传至第2～3代的NSCs尚未分化时移植最佳；④体外培养的NSCs能自我调控分化为神经元、星形胶质细胞、O2少突胶质细胞、雪旺氏细胞染色阳性克隆球和前体细胞；⑤各种子代克隆球和细胞存在广泛的突触联系；⑥NSCs与OECs联合培养时，不需丝裂原刺激即能形成克隆球，获得大量Vimentin、GFAP、MAP2、O2、p75NGFR、GFAP、S-100、Synaptosis、Vimentin、Tau(Tau只有人HNSCs+HOECs联合培养时出现阳染)染色阳性的克隆球和细胞；⑦脊髓研磨后的上清液刺激神经干细胞向神经元方向分化，但并不出现终末分化；⑧本研究培养条件不利于成纤维细胞、O4生长。

Today the classroom studies several hundred several dozens adds several hundred several dozens, in the classroom only then my sounds of people rip the strength to use up, speak one's mind, nobody listens to me to teach, below plays respectively each, all is I is putting on a one-man show, this academic society, has not learned, also the surplus many topics have not done, has not completed the task, this hall class has been defeated, was simply forces an analogy, in the book inspected the wrong topic let the student class get down the office to change wrong, the student did not go.

Classical Chinese article sentences make pauses in reading unpunctuated ancient writings mediumly, it is the person that use " commonly, also " will express, also be with " sometimes, for, criterion, all, it is " express, the watch denies judgement is not "," with " not "," does not have "," not ".

文言文中的判定句，一般是用"者、也"来表示，有时也用"乃、为、则、皆、是"等表示，表否定判定用"非"、"未"、"无"、"莫"等。

But "does not include" does not mean the black Dalbergia Romer's absolutely no drugs, there may be individual "problematic" because the plant has not been found who have not been included in the "poison wood directory" in the.

但&不包括&并不代表卢氏黑黄檀就绝对没毒，也可能会有个别&有问题&的植物由于没有被发现而未被列入到&毒木目录&中。

But now, if I be marching on with my utmost vigour in that way which, according to the sacred geography, leads straight to Jerusalem, why am I beaten and ill-used by others because, perhaps, I wear not buskins; because my hair is not of the right cut; because, perhaps, I have not been dipped in the right fashion; because I eat flesh upon the road, or some other food which agrees with my stomach; because I avoid certain by-ways, which seem unto me to lead into briars or precipices; because, amongst the several paths that are in the same road, I choose that to walk in which seems to be the straightest and cleanest; because I avoid to keep company with some travellers that are less grave and others that are more sour than they ought to be; or, in fine, because I follow a guide that either is, or is not, clothed in white, or crowned with a mitre?

但是现在，如果我正依据那个引导人到耶路撒冷的神圣地理学劲头十足的开始我的长途跋涉，为什么要被他人暴力虐待和折磨？可能因为：我没有穿高统靴；或者我的头发未按某种样式修剪；或者我未按某种方式受洗；或者在路上我吃了肉或其它很对我胃口的食物；或者我绕开了一段在我看来要导向荆棘或悬崖的路；或者在几条通向目的地的路中我选了一条在我看来最近最好走的路；或者我避免与不怎么严肃的人以及过于酸腐的人为伴；或者，最后，因为我跟随了一个穿或未穿白衣，戴或未戴主教头冠的人。

Love you to make you happy soon, I think it is right, even if you are not my not mattering, I on so long as at my side in you, I happy to know you, I so long as you can be happy , other I do not dare to expect , just like this because of me , I have not regretted , thank you proud to bring I, bring satisfication of me, I what does it can make now?

爱你就要让你幸福，我想是对的，就算你不是我的都无所谓，我就只要你在我身边，我就知道你开心，我就只要你能幸福，其他的我不敢期盼，因为我就这样，我没有后悔，谢谢你带给我骄傲，带给我的满足，我现在能做什么？
