We suppose that there is a presently undefined subfraction of stem cell population that exists in a number of tissues beyond embryonic development. We term them postembryonic pluripotent stem cells. They differ from embryonic stem cells in that they gradually lose some differentiation potentials during development and adopt some special phenotypes once within a certain tissue. They can give rise to different kinds of stem cells; therefore, help to maintain balance during development and metabolism. They provide cells not only for the damaged tissues they reside, but also for damaged tissues different from them by migration triggered by proinflammatory cytokines or growth factors.

我们认为在胚胎发育后的多种组织中都存在一类原始干细胞群体，它们和造血干细胞、神经干细胞等多能干细胞不同，后者只能分化为特定胚层的细胞，而这类原始干细胞可分化为不同胚层的组织细胞；另一方面，它们区别于胚胎干细胞，在妊娠期间会逐渐失去部分分化潜能，并且会出现一些特殊表型或者分子标志，我们称其为胚胎后亚全能干细胞，这类干细胞具有下列特性：可分化为不同胚层的细胞，分布于身体的所有组织和器官，具有相同的表型或标志；他们在胚胎期存在于一些或全部的组织和器官中，可分化为不同类型的多能干细胞并在生长发育和新陈代谢中维持这些多能干细胞保持平衡；可以参与机体自我修复和更新，不仅能分化为所在器官的组织特异性细胞，参与器官重塑，也可以在炎症因子或者生长因子的趋化作用下，远处转移修复受损组织。

The consumption of the commodity represents a means to perpetuate our enjoyment of appearances but also a means of returning to a condition of self-control: keeping the senses busy but satisfied, as in the case of the addict who requires a daily dosage of drug to recover his sense of normality, has become a balanced life for many of us, with the result being of course the production of even more commodities that further sensualize life, especially when this also represents a learning process for the spectacle, always eager to discover and capitalize on patterns of popular needs as suggested by the introduction of new commodities.

消费的商品是一种手段，我们享受永久的表现，而且手段返回的一个条件，自我控制：保持忙碌，但感觉不满意，如吸毒者谁需要每天剂量的药物他的意识恢复正常，已成为一个平衡的生活对于许多人来说，其结果是当然的生产更商品，进一步sensualize生活，特别是当这也代表着一个学习的过程为奇观，总是急于发现和利用模式的流行需求，建议采用新的商品。

He then says:"So many of the Chows today are being developed so that the legs are entirely too short, and the body instead of being square, is oblong. Let us not only breed for a magnificent head and a tremendously wide chest, but let us develop a Chow proportionately; body, legs, head and gait; if we are going to glorify our Chows, we must keep them properly balanced."

然后他说：现在有好多的松狮都得到发展以至于它们的的腿都开始变得越来越短，身体就变得近似正方形，但原本应该是长方形的，我们不要一味的只要求它们有漂亮的头部和特别宽阔的胸脯让它们的身体，腿部，头部以及步态都能够按照一定的比例得到发展，，如果我们想美化我们的松狮就应使他们保持平衡。

Obama to task for self-consciously italicizing parallels between himself and Lincoln, there are in fact a host of uncanny correspondences between these two former Illinois state legislators who had short stints in Congress under their belts before coming to national prominence with speeches showcasing their eloquence: two cool, self-contained men, who managed to stay calm and graceful under pressure; two stoics embracing the virtues of moderation and balance; two relatively new politicians who were initially criticized for their lack of experience and for questioning an invasion of a country that, in Lincoln's words, was "in no way molesting, or menacing the U.S."

尽管一些批评指出奥巴马自觉地突出他与林肯之间的并列，但这两位都自己获得过国会短暂任期的前伊利诺斯州议员，在运用展示他们的雄辩的演讲获得全国性的声望之前，事实上确实有许多不寻常的相似性：两人都有点冷酷并自我控制，都可以在压力之下保持冷静和优雅；两人都清心寡欲，信奉中庸和平衡的美德；两人相对来说都是稚嫩的政治家，他们最初都因缺少经验，以及用林肯的话来说是&绝不打扰或威吓美国&地质疑对一个国家的侵占而受到批评。

When the flow through the balance of the piston damping the flow of holes increases, the balance of the piston, the next increase in pressure on both sides of a balanced increase in the distance the piston increases, and vice versa reduced; and also because the spring stiffness is very small, so that shift the balance of the piston pressure required very few changes, so the flow through the Poppet head is not much change, so the first opening Poppet very few changes, to mention the pressure of moving the first opening can be said to remain unchanged, that is, when the pilot valve spring after a set, Poppet Head was opened, the balance piston chamber pressure remained basically unchanged.

当流经平衡活塞上阻尼孔的流量增加时，平衡活塞上、下两侧的压差增加，平衡活塞上升距离增加，反之则减小；又因为弹簧的刚度很小，使平衡活塞上移所需压差变化很小，所以通过提动头的流量变化也不大，因此提动头的开口变化很小，提动头开启的压力可以说是不变的，亦即当先导阀的弹簧一经设定后，提动头被打开时的平衡活塞上腔的压力基本保持不变。

So the sustainable growth is well accepted as the best way to enhancing regional economy. Economic growth can be kept at a reasonal speed and rate through the rational and balanced capital accumulation. In this process to control the best balancing point is the vital link.

区域经济增长容易步入的歧途是不可持续的增长和扭曲的增长，在发展区域经济的过程中，最佳的增长方式是可持续增长，即通过有序和平衡的资本积累来保持经济以一个合理的速度和比率增长，因此经济增长中的平衡点的控制是至关重要的环节。

Comparison of different types of stem cutting in rooting induced and analysis the cDNA clones which may be associated with the occurrence of adventitious roots of P.euphratica,the model of ARF were initial establishment of exogenous IBA controlling endogenous IAA occurred threshold and equilibrium,that is,exogenous IBA receiving by receptor of stem cutting,and transfer into the cells,then turn into active IAA by the effects of the POD enzyme.

通过对胡杨3个不定根发生调控培养体系的比较和与胡杨不定根发生可能相关的差异基因的克隆分析，初步建立IBA调控胡杨不定根发生的内源IAA阈值和激素间平衡的模型，即外源IBA通过插穗受体接收，转入细胞内并在POD酶作用下转化成具有活性的IAA，当IAA的水甲在促根的阈值内并保持相对平稳时，则有利于生根；当IAA的浓度增高超过阈值且不稳定时，则抑制不定根的发生。
