Observations on the dichotomous leaf venation of Circaeaster agrestis found no intermediate forms of the fusion of vascular bundles between the two completely fused commis-sural veins of anastomoses and the two separate approximate veins, but found different degrees of the vestige of commissural veins .

在星叶草叶二叉分枝脉序中，网结脉中2条完全汇合叶脉与靠近脉中完全分离叶脉间未发现任何形式的维管束汇合的中间类型，相反观察到了网结脉中不同程度的连接脉退化的痕迹，因此网结脉不可能由靠近脉形成；盲脉的出现与齿的退化、网结脉中连接脉的间断及非网结脉由分枝处间断等相关；上述事实表明星叶草叶的二叉分枝脉序应为一减化性状。

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。

The study shows that the advantageous sandstones in the area have the following distribution characteristics: in the environment of growth faults, sandstones are mainly distributed in the downthrown block of a boundary fault; in a lowstand systems tract, sandstones are mainly distributed in lowstand wedges, slope fans, basin-floor fans, fan deltas, deltas and submarine canyons; in a transgressive systems tract, sandstones are mainly distributed in sandbars and sand-beaches; and in a highstand systems tract, sandstones are mainly distributed in deltas, fan deltas and submarine fans.

并指出有利砂体的分布特征：低水位体系域，砂体主要分布在低水位楔、斜坡扇和盆底扇；高水位体系域，主要分布在三角洲、扇三角洲、海底扇和峡谷水道。研究表明，以层序地层学理论为指导，划分层序和体系域，进而对有利砂体进行预测，对该地区油气勘探有重要指导意义。
