Effects of four-level combinations supplementing with VA, VD and VE (VA: 4 000, 6 000, 8 000, 10 000 IU/kg; VD: 920, 1 380,1 840, 2 300 IU/kg; VE: 6.4, 9.6,12.8,16.0 IU/kg) in diets of laying hens were studied.

将240只海兰褐壳品种17周龄末育成鸡分成4组(每组4个重复，各15只鸡)进行33周试验，研究了4个维生素A、D、E添加水平组合(VA 4 000、6 000、8 000、10 000 IU/kg，VD 920、1 380、1 840、2 300 IU/kg，VE 6.4、9.6、12.8、16 IU/kg)的效果。

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。

The selection of high-quality corrosion-resisting coatings and insulation materials, strengthening of routine maintenance and above-ground laying of pipelines are the effective measures to preve...

The presence of Pt significantly improved the resistance to γ′-Ni3Al formation, promoted selective oxidation of aluminum by preve nting the transport of other elements outwards to Al2O3 scale and resulted i n the formation of purer, slower-growing and more adherent Al2O3 scales, de laying the onset of scale spalling for two types of coatings and of oxide nodule s growth for the high aluminum activity coating.

Pt的存在，通过阻止合金元素穿过Al2O3膜向外扩散，形成更纯的、结合力更好的Al2O3膜。并且，Pt的存在抑制γ′-Ni3Al相的形成，推迟涂层的高温退化和高铝活度涂层中非铝氧化瘤的生长。

Based on the principle of "Giving first place to safety and laying stress on prevention" and requirements of power safety production, the whole-process safety identification system was established with emphasis on the key points of protection device checking, electrical equipment maintenance, preventive tests, and safety-related operational work. The system is expected to ensure safety of site operation of 500kV substations and prevent happening of faults due to operational and managerial peccancies.

阐述坚持&安全第一，预防为主&的原则，按照现有电力安全生产的各项措施要求，针对500kV变电站内保护装置校验、电气设备检修、预防性试验及运行操作中涉及安全的关键节点，从作业准备、实施到结束，全过程地建立安全鉴证制度，确保500kV变电站现场作业安全，遏制各类行为性违章和管理性违章造成的人身、电网、设备事故的发生。
