The results showed the radioscaphocapitate,radiolunate,ulnolunate,ulnotriquetral and dorsal radioulnotriquetral ligaments were composed of densely fasciculated collagen fibers which contained more elastic fiber.

结果显示，桡舟头韧带、桡月韧带、尺月韧带、尺三角韧带和腕背侧桡尺三角韧带中均可见致密粗大的胶原纤维束，束内含有大量的弹力纤维；桡舟月韧带中缺乏弹力纤维，但含有丰富的血管；腕尺侧副韧带中无明显的胶原纤维和弹力纤维可见。

The results showed that three reasons caused the failure of the fibre materials:1the fibre materials transforming into powder which was caused by the precipitation of mullite at high temperatures;2cracking and spalling of the refractory coating and refractory fibre felt;3low strength of the refractory fibre flet.

结果表明：硅酸铝质耐火纤维在高温下析出莫来石晶体导致纤维材料的粉化，耐火涂层和耐火纤维毡的开裂、剥离脱落，耐火纤维毡强度很低是导致纤维材料失效的3个主要机理。研究结果为新型耐火材料的研制或改进提供了重要依据。

During solidification,α-Al phase nucleates first in the interstices between the short fibers and grows gradually toward the surface of Al2O3 short fibers. The content of Cu and La element around the surface of Al2O3 short fibers increases, both of them enrich almost in the same region, but the content of Cu element in the interstices of short fiber decreases gradually.

结果表明：Al2O3纤维与基体间润湿良好，生成了致密的界面层；在凝固过程中，α-Al相在短纤维间隙中形核并向纤维表面生长，纤维表面Cu和La元素的浓度增大，纤维间隙中的Cu元素的浓度减小。

To understand the infectivity by porcine endogenous retrovirus with porcine skin fibroblast cell in vitro and in vivo, porcine skin fibroblast cell established by our laboratory were co-cultured with neo/HEK293 cell for the infection of RERV in vitro, and were subcutaneously transplantated to SCID (severe combined immuno-deficiency) mice for the infection of PERV in vivo, laying the foundation for valuation of biologic safety of xenotrans-plantation. The event of neo/HEK293 cells infected by PERV occurred during co-culture of porcine skin fibroblast cells with neo/HEK293 cells, expanding the rang of the infection of porcine endogenous retrovirus. Afterpig cells transplantated subcutaneously in SCID mice, the microchimerism (78.57%) of pig cells occurred widel, and there was phenomena of integration of PERV provirus (85.71%) in several organs or tissues remote from the injected sites, indicating infection of PERV in SCID mice in vivo. yet, there is no evidence of active viral replication in analysis of PERV env RNA of these tissues or organs.

为了解猪皮肤成纤维细胞PERV在体外和体内的感染性，通过建立猪皮肤成纤维细胞系，将所建细胞系与人胚胎肾293细胞体外共培养，并移植于严重联合免疫缺陷鼠皮下进行猪皮肤成纤维细胞PERV的体外和体内感染性实验，结果表明，猪皮肤成纤维细胞与人胚胎肾细胞共培养过程中，猪内源性逆转录病霉感染人胚胎肾细胞，进一步证实和拓宽了猪细胞PERV感染人细胞的范畴；猪皮肤成纤维细胞移植SCID鼠皮下后，导致SCID鼠发生猪细胞微嵌合(78.57%)和PERV在体内感染(85.71%)并且波及远离移植部位的多种组织或器官，但是并未检测出SCID鼠组织中表达PERV env RNA。

Three composites of the different fibers with epoxy resin matrix are prepared and the corresponding unilateral fiber reinforced winding ring specimens are fabricated.

对由PBO纤维与环氧树脂基体复合成型的单向纤维增强环形试样，测试了其拉伸强度、弹性模量和层间剪切强度，结果表明：PBO纤维股纱的拉伸强度比F - 12和Kevlar - 4 9分别高 2 4 4 %和 5 2 8%以上，单向纤维复合材料的拉伸强度分别高约 37 2 %和 92 8%，耐热性也高约 166℃，但PBO纤维与环氧树脂基体的界面粘结性很差，层间剪切强度仅为 2 3～ 2 7MPa 。

The wear debris of three semi-metallic friction materials reinforced by low carbon steel fiber, brass fiber and pure copper fiber respectively, and grey cast iron couple woren at different temperatures were studied by XRD and EDAX. Wear properties were analyzed together with the surface images got by scanning electron microscope.
