Coli might be distributed in all the gene. The intact Hu-P68 cDNA ORF including 10bp upstreams of ATG were obtained by PCR deletion and reconstruction. The resulted fragment were cloned into transfer vector pBacPAK〓 at Bam HI site and lipofectioned into 〓 cells with Bsu 36I digested genomic DNA of insect baculovirus BacPAK 〓.

利用PCR技术删除人P68 cDNA翻译起始位点上游10bp以外的5'UTR，并引入BamHI位点，经酶切和测序验证后，将此改造的完整P68 cDNA基因编码区装入转移载体pBacPAK〓，用脂转染法将此重组质粒与酶切的昆虫杆状病毒BacPAK〓基因组DNA片段导入昆虫细胞〓中，经同源重组获得了再生病毒。

Relying on both dynamic and static analysis methods,both microstructure and macrostructure analysis methods,both on-line and off-line analysis methods,as well as both along-line sampling and die sampling techniques,the author of this thesis studied and developed an on-line microscopic system,the on-line rheometers and the on-line samplers which are used in single screw extruding process for the first time. Based on the analyses of a plenty of experimental results, the thesis mainly discussed following several questions: solid-bed break-up phenomenon on macroscopic scale,melting and deforming mechanism of a solid particle on small particle scale,and polymer morphology on microscopic scale.
