The outer neuroblastic layer before it divided to inner and outer nuclear layer and outer complexiform layer and gonglion cell layer showed a temporal PCNA positive which was related to proliferation. The three cell layers had another PCNA positive when finished time changed from outer to inner after their morphologic development basically completed( outer nuclear layer:11～15 days,inner nuclear layer: 8～16 days, gonglion cell layer:16～21 days).

PCNA显示在外成神经细胞层分化为内、外核层和外丛状层之前，和节细胞各有一次和增殖相关的阳性表达。3个细胞层在形态学的分化基本完成后，又出现了一次结束时间是由外向内变化的阳性过程（外核层：第11天至15天：内核层：第8天至16天，神经节细胞层： 16天到21天，这一次阳性表达过程可见到细胞形态向成年形态的转化。

The study was done to compare the induction efficiency of human embryonic stem cells to neuroepithelial progenitor cells in human embryonic fibroblasts,mouse embryonic fibroblasts and feeder free systems.

中文摘要：［摘要］比较人胚胎干细胞在人胚胎成纤维细胞、鼠胚胎成纤维细胞饲养层和无饲养层3个诱导体系下形成神经上皮祖细胞的能力。

Studies on rock and ore micro fabric that control mineral preservation stratum of the deposit,and the siliconization and pyritization contacted with gold mine origin reflects the characteristic of syndepositiondiagenesis,which indicates the sediment-diagenesis and later stage mild reconstructive genetic mechanism of Shuiyindong gold deposit.

黔西南水银洞金矿是一特大型富金矿床，矿体成群多层、顺层产于龙潭组地层中，通过系统研究水银洞金矿赋矿地层岩石及矿石的显微组构特征，以及与金矿成因联系密切的硅化及黄铁矿化特征，均显示为同沉积—成岩特征，共同指示水银洞金矿沉积—成岩后期轻微改造的成因机制。

As pH value varied in the course of diagenesis,reservoirs experienced one to three cementations or dissolution generations.Lots of secondary dissolution pores developed in the late diagenetic stage,because of the acidic mediums in the process of generation and migration of oil and gas. The anhydrites deposited in the dissolved pores resulted in the heterogeneity of secondary pores.

储层在成岩过程中受地层水pH值变化的影响，经历1~3个世代的胶结或溶蚀作用，其中在晚成岩期油气生成和运移过程中形成的酸性成岩环境对早成岩期生成的碳酸盐岩胶结物和储层中的长石矿物溶蚀，因而产生了大量的次生溶孔，但随后在溶孔中沉淀了不等量的硬石膏，导致了次生孔隙的非均质性。

So from the aspects of economical and social benefit, it has a lot of advantages. On the other hand CFG pile with long screwy drill pipe inner pump pressure is low noisy and without muddy water pollution; The process of drilling will not lead to vibration and has the capacity to penetrate hard rock layer; Also the construction is of high efficiency.

并且长螺旋钻管内泵压成桩工艺具有低噪音，无泥浆污染；成孔制桩时不产生振动；成孔穿透能力强，可穿透硬土层，诸如沙层、圆砾层和粒径不大于60mm的卵石层；施工效率高等优点，所以该技术在全国推广后，得到了广泛的应用，目前已成为应用较为普遍的地基处理技术。

The hFCECs were cultured by sticking tissues piece method that the cornea were divided into the limbus and central tissue piece and digestive method,respectively.For digestive method,the digestive juice of 5mg/ml DispaseⅡ+0.25%trypsin was chosed.D/F12 with 10%fetal bovine serum and 100 U/ml penicillin and streptomycin were used in this study,the culture condition was 37℃and 5%CO2,and culture medium changed every three days2、Passage of hFCECsAfter more than 80%confluenced,cells from corneal limbus hFCECs were digested for 5-15min with different concentrations of trypsin/EDTA at 37℃,and then passaged at a ratio of 1:2.The cells were subcultured on empty plates,mouse 3T3 fibroblast feeder layer,fetal corneal stromal cell feeder l ayer or HTK feeder layer respectively.And D/F12, mouse 3T3 fibroblast conditioned medium,fetal corneal stromal cells conditioned medium or HTK conditioned medium with 10%FBS and 100 U/ml penicillin and streptomycin were used respectively as the culture medium.And the culture medium were changed every three days as well.

方法一、人胎儿角膜上皮原代和传代培养1、原代培养严格无菌操作获取人胎儿角膜片，采用组织块贴壁法、酶消化法原代培养人胎儿角膜上皮细胞。2、传代培养角膜缘部的细胞生长融合达80%以上，不同稀释浓度的胰酶/EDTA消化液消化传代分别接种于空板、小鼠3T3成纤维细胞饲养层、胎儿角膜基质细胞饲养层及HTK饲养层，培养液分别采用D/F12、小鼠3T3成纤维细胞条件培养液、胎儿角膜基质细胞条件培养液、HTK条件培养液。
