A white fatty substance that forms a medullary sheath around the axis cylinder of some nerve fibers.

一种白色油脂物质，形成一些神经纤维轴突外包裹的一层髓鞘。

Sheath around the axis cylinder of some nerve fibers.

一种白色油脂物质，形成一些神经纤维轴突外包裹的一层髓鞘。

The differentiation and maturation of SC depend on axon, and the activity of integrins is expressed by axon.

在SC的分化成熟及髓鞘形成的过程中，轴突及细胞外基质的作用不可忽视。

We can see the burst apart bone block in the hinder margin of the centrum except the nucleus pulposus tissue.

Objective:To observe the effect of treatment on serve backpain after chemonucleolysis with caudal analgesia.

目的：观察骶管内硬膜外腔封闭处理髓核化学溶解疗法术后严重腰痛的疗效。

Results Of 6 cases, 3 were found in conus medullaris, 2 in thoracal segment, 1 in cervical segment; 4 cases were subdural teratoma, 2 in conus medullaris teratoma.

结果 畸胎瘤位于脊髓圆锥3例，胸段2例，颈段1例；髓外硬膜下4例，脊髓圆锥内2例。

Large numbers of experiments internal and external had confirmed both direct current and square pulse of distal end cathodal could improve peripheral nerve regeneration, because it could speed up transmigration, creeper, growth and development of cell Schwann, derivate growth of nerve fiber; it also increased blood capillary of epineurium, brood blood vessel, amendment ischemic of impaired nerve, it still could accelerate Wallerian

国内外大量的基础实验及临床研究都证实远端负极电流的直流电场及脉冲电场等均有促进周围神经再生的作用，认为其可加速Schwann细胞的游走、爬行及生长发育，诱导神经纤维的生长；电刺激还能促使神经外膜毛细血管数量增多，扩张血管，改善神经损伤段缺血状态，并加速Wallerian变性及崩解组织的清除，为Schwann细胞发育和髓鞘化过程提供充足的能量与物质，同时为神经轴突的再生提供良好的内环境；在神经断端出现瘢痕或神经瘤时，电刺激可增加神经纤维穿越瘢痕的能力。

Shows that of all types casparian strip exits in endodermis and evident pith does in young root; primary xylem is exarch and tetrarch

结果表明：内皮层都具有凯氏带，幼根均具有明显的髓，初生木质部均为外始式四原型；

The lateral branch is thicker with the average length of 58.2 mm avaliable for the reconstruction purpose; the diameter is in average of 1.46 mm, the number of fibers is in average of 1 519; 90.4％ of the lateral branches redivided into 2 or 3 branches.

外侧束在背阔肌内可利用的长度平均为58.2mm，直径平均为1.46mm，有髓纤维数平均为1519根，90.4％的外侧束可再分为2支或3支。

Through comparing exon sequences at both ends of introns of CHD genes of jungle fowls and cygnets, exons on two ends thereof are respectively designed with an upstream primer and a downstream primer: Psf: 5'CAAGGATGAGAAACTGTGCAA3'; and Psr: 5'GAATATCTTCTGCTCCTACTG3'; and the Psf/Psr primers are used for amplifying the CHD genes on Z and W chromosomes of meat pigeon feather pulp genome DNA, and finally the sex is identified according to the band type through 10 percent polyacrylamide gel electrophoresis and silver staining, wherein, female shows two bands and male shows one band.

通过原鸡和小天鹅CHD基因内含子两端的外显子序列比对，在两端外显子上分别设计上下游引物：Psf：5'CAAGGATGAGAAACTGTGCAA3'；Psr：5'GAATATCTTCTGCTCCTACTG3'；再以Psf/Psr引物扩增肉鸽羽髓基因组DNA的Z和W染色体上的CHD基因，最后经过10％聚丙烯酰胺凝胶电泳、银染，根据带型判断性别，其中雌性为两条带，雄性为一条带。

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

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
