Chinese Science Bulletin 1999年第8期44卷 715-719页

作者： WU Zhijian, WU xiaobing and hou YundeState Key Laboratory for Molecular Virology and Genetic Engineering , Institute of Virology , Chinese Academy of Preventive Medicine , Beijing 100052, China Corresponding author State Key Laboratory for Molecular Virology and Genetic Engineering Institute of Virology Chinese Academy of Preventive Medicine Beijing China

The generation of a recombinant HSV (rHSV) that can provide packaging function for rAAV production is described. A set of cosmids including cos48, cos28, cos6, cos14 and cos56, which represents the HSV-1 genome was used for generation of this rHSV. Rep and cap genes of AAV-2 were inserted into Xba Ⅰ site of UL2 gene on cos6, generating cos6-rcΔUL2. After being digested with Pac Ⅰ , cos6-rcΔUL2 and the other 4 cosmids were cotrans-fected into BHK-21 cells. The recombinant virus HSV1-rc/ΔUL2 carrying rep and cap genes was generated due to the homologous recombination of the 5 cosmids. The results showed that the existence of rep and cap genes on this rHSV was stable from passage to passage and the rHSV could support the packaging of rAAV either in cells transiently transfected with AAV vector or in stable cell line harboring AAV vector. Further modification of this rHSV and optimization of conditions involved in rAAV preparation may lead to a large-scale production of rAAV in the near future.

溶液除湿空气调节装置具有不受气候和地域限制的特点,是最可能被大规模推广的空气调节技术之一。本文进行了逆流填料式单级LiCl溶液除湿过程实验研究,针对除湿过程,研究了进口空气的温度(30~36℃)和相对湿度(50%~70%)对除湿性能的影响。结果表明,除湿性能会随着进口空气温度或相对湿度的升高而增强。此外,针对溶液再生过程,本文考察了再生风进口温度和再生溶液进口温度对再生性能的影响,结果表明,两个温度值的升高均会增大再生能力,且后者的作用更强,但是再生溶液出口温度也会随之上升,从而导致了系统冷源负荷的增大。

依据对江西省农民工的问卷调查数据,对农民工参与职业教育与培训的意愿及影响因素的实证研究发现:农民工对于参与职业教育的经济成本比较敏感;处于中等地位水平的农民工参与职业教育与培训的意愿最为强烈;农民工对职业教育与培训的预期收益越低,对于职业教育学校的评价越低,对于自身生活现状越满意,现代性水平越低,就越不愿参与职业教育与培训。为此,政府及职业教育部门应从刺激需求的角度出发,增加对于农民工参与职业教育与培训的补助水平,加强对于职业教育学校的管理与考核,提高办学质量,提升职业教育的公众吸引力。
