It is shown that nanoscale pyramid cone shapes are found on the metal film interface (100), serrate steps are found on the metal film interface (111), and cystiform shapes with terrace structure are found on the cross-section near the catalyst. Other faults have brittleness fracture characteristic with nanoscale clusters are found on the fault surface.

The RT-PCR product was inserted into pTG19-T vector and transformed into E. coli successfully. By blastn, the sequence results of Kunming mus musculus were in complete accordance with the conservative sequence of Genbank NR_003278 (791bp-1153bp). By Blastn in NCBI, the sequence with little difference among animals was confirmed to be conservative. After Blastn, fourteen complete CDS coding for different animals were chosen. According to VECTOR NIT 9.0 software, the similarities between Kunming mus musculus and bos taurus, homo sapiens, erinaceus europaeus, cricetulus griseus, sus scrofa, dasypus novemcinctus, rattus norvegicus, rabbit, equus caballus, macaca fascicularis, didelphis virginiana, monodelphis domestica and vombatus ursinus was 67%, 100%, 100%, 36%, 100%, 100%, 67%, 100%, 100%, 92%, 99%, 99% and 99%. In the phylogenetic tress constructed with the forteen 18S rRNA by Treeview, the Kunming mus musculus clustered with cricetulus griseus, sus scrofa and rabbit, which was nearer to cricetulus griseus and was most far away from macaca fascicularis.(3) After sencodary structure analyses of 18S rRNA of mus musculus, an oligonucleotide fragment for RNAi was designed and synthesized, which was transformed into plasmid, and restriction enzyme analyses and sequencing results should the expression plasmid pGPH1/ GFP/Neo-mouse-sh 18S rRNA were constructed for RNAi successfully.

结果①通过RT-PCR检测显示18S rRNA基因在小鼠卵巢组织和单个GV期、MⅠ期卵母细胞中均有表达，且在未成熟卵母细胞中，MⅠ期的表达明显强于GV期的表达；②RT-PCR产物克隆测序结果显示：昆明小鼠18S rRNA基因保守区序列与基因库序列[NR_003278保守区部分(791bp～1153bp)]完全一致；Blastn比对结果发现：在不同物种中差异较小，选出14种生物18S rRNA全序列经VECTOR NIT 9.0软件分析，提示昆明小鼠18SrRNA与牛、人类、刺猬、中国仓鼠、猪、犰狳、褐鼠、兔子、马、食蟹猴、负鼠、短尾猊、袋熊的18S rRNA的相似率依次为67%，100%，100%，36%，100%，100%，67%，100%，100%，92%，99%，99%，99%；Clustal 1.81和Treeview构建出的分子进化树表明：在上述14种生物中昆明小鼠与中国仓鼠进化关系最近，与兔子、猪聚成一簇，与食蟹猴进化关系最远；③根据18S rRNA二级结构设计并合成RNA干扰寡核苷酸片段，重组质粒经过限制性内切酶及测序表明成功构建了pGPH1/GFP/Neo-mouse-sh 18S rRNA干扰表达质粒。

This paper analyzes the principle of the LP-LFC process,presents the physical and mathematical models of mould filling of the new process. The patterns including window-plate, ladders cluster, electromotor frame and exhausting manifolds are poured using LP-LFC process with AZ91D alloy, and the mould filling course is tracked with electrode touch point method. Based on above tests and experiments,the casting defects including short runs, cold laps, trapped gas,metal penetration, and so on, were investigated. The appearance characteristics,birth causes and influence factors of above defects are discussed in the article,diagrammatize modes of the defects forming is also given, and the measures of reducing or avoiding defects are put forward.
