数量上

Fund Project: the National Natural Science and Technology Source Program, No. 2001DEA1006*Abstract: Number of neural stem cells is small. NSCs look like circle or ellipse with or without short neurite, with large nuclear-cytoplasmic ratio and deep karyotin. NSCs have no visible differences with other kinds of cells in appearance, and have no cell surface marker. Currently, there are mainly three aspects to identify NSCs: expression of specific nerve antigen, including nestin, Musashi, transcription factor, and cell adhesion molecules; self-renewal ability including single cell clone analysis, BrdU mark and S phase cell; the potential of multi-direction differentiation including immunocytochemical process and reverse transcriptase polymerase chain reaction.

由于神经干细胞的数量很少，从细胞形态来看神经干细胞为圆形或椭圆形，无或有较短的突起，核质比大，核染色较深，形态上与其它种类的细胞没有明显的差异，并且未找到一种细胞表面特异性标志物，因此目前鉴定神经干细胞主要有以下3个方面：特异性神经抗原的表达，包括巢蛋白、Musashi、转录因子及细胞黏附分子；自我更新能力，包括单细胞克隆分析、BrdU标记S期细胞；多向分化潜能，包括免疫细胞化学法、聚合酶链反应色法。

Given two bridge-builders, a man and a woman, given a certain bridge to be built, and given as always the unchangeable laws of mechanics in accordance with which this special bridge and all other bridges must be built, it is simply inconceivable that the preliminary instruction given to the two bridge-builders should differ in quantity, quality, or method of presentation because while the bridge is building one will wear knickerbockers and the other a rainy-day skirt.

假定分别有男女两位桥梁建造者，要去建造指定的一座桥，在建造这一独特的桥及其它一般的桥的力学规律总是不变的情况下，简直不可想象，男女建造者所受的基本教育应有所不同；更不可想象，只是因为在施工时，一个穿灯笼裤，另一个穿防雨裙，而必须让他们在质量、数量及教学方法上接受不同的教育。

Corporate group is a combination of two or more undertakings. However, from the legal points of view, the essentiality of a corporate group does not lie in this, but in the controlling existing between undertakings within a corporate group.

企业集团是两个或多个企业的联合，但从法律上看，企业集团的本质属性并不在于此，而在于企业集团内企业之间的控制关系，这与集团内企业的数量和规模无关。
