The ligamentous scaffold material were made from the PVA fibers by braiding technique. The mechanical properties of the scaffold materials were measured using the electronic materials testing machine. Human ACL cells were isolated and cultured by tissue explant and collagenase digestion methods, the morphous characteristics of cells and the secretion of collagen protein were measured. In order to observe the biocompatibility between the material and cells, ACL cells were in vitro expanded and seeded on the scaffold materials.

方法］用聚乙烯醇纺丝纤维编织构建韧带支架材料，在电子拉力机上测试该支架材料的力学性质；用组织块和胶原酶消化培养法在体外分离培养人前交叉韧带细胞并对细胞的生长形态和分泌胶原蛋白的特征进行检测，细胞经体外扩增后种植于编织构建的聚乙烯醇韧带支架材料上观察。

Result The flexibility of the scaffold material was powerful. The load-elongation curve of the mechanical testing was similar to that of ACL, the maximum load, the ultimate stress and the Young's modulus of the scaffold materials were 52.61 N, 14.96 MPa and 202.08 MPa respectively. Human ACL cells displayed the representative characteristercs of the ligamentous fibroblasts, and synthesized extracellular matrix, such as type Ⅰand Ⅲ collagen protein. The scaffold materials had no cytotoxicity. Human ACL cells adhered, grew and proliferated well both on the surface and in the holes of the scaffold materials.

First, we investigate the methods of sepiolite s purification from ore , from which we get the incompact short fibrous sepiolite for the experiment ; the prime activatited term is also obtained through this experiment. We use activated sepiolite to process the absorption experiment on heavy meatal ion ( Ni2+, Cr6+, Pb2+, Cu2+, Cd2+), noble metal ion, dynamite cotnposton in water and industrial oil. we take Ni2+ for example to confirm the prime adsorbent term , from the experiment we get the adsorbent isotherm . Make the dynamic absorption experiment and regenerate experiment using sepiolite on the heavy metal(Ni2+) on the base of static absorption experiment.

At the mean time,the culture mixed with the fibroid cells which grew well respectively.Fine single layer was formed and covered the whole amniotic membrane on which the LECs grew membranously,and the fibroid cells outgrew the LECs.

同时，生长的上皮细胞中有成纤维样细胞的混杂生长，但各自保持其良好的细胞形态。3周左右形成良好的单层，细胞生长呈膜片状扩展，整个羊膜之上铺满细胞，有明显的扩展界限。

Among them are the indefinite shape mesenchyma.

在电镜下发现中段大直径胶原纤维明显多于上、下段（P＜0.01）。

When reached logarithm growth phase, it was poured or the medium was removed. 5 mL medium containing 10 mg/L mitocin-C was added , kept at 37 ℃, and then cultured in saturated humidity warm box with the CO2 of 0.05 fraction volume for 2 or 3 hours. It was coated with 0.1% gelatin in 6-hole plate, laid for over 30 minutes, and then threw away or the medium with mitocin-C was removed, washed with phosptat buffer for 5 times so as to remove the mitocin-C. 2 mL 0.05% trypsin digestive cells were added, and it was observed under microscope. When crevice appeared, cells became round (about 2－4 minutes), digestion was stopped by adding medium of the same volume, and blew up with straws repetitively to make it into monoplast suspension. Special-used cover glass was put in the center of cell counting chamber. Cells were sucked in by glass siphon, and cell suspension flew out at bucket of up or down-sides of counting chamber, until the cover glass was filled with fluid. Living cell were inoculated at concentrations of 3×108, 5×108, 1×109 L－1 after their number counted.

Results Myoid/myofibroblastic differentiation occurred most commonly in fibrosarcomatous DFSP. It was recognized histologically as peripherally distributed or randomly scattered small eosinophilic nodules or short bundles, which were composed of bland spindle cells, closely resembling smooth muscle cells or myofibroblasts.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
