担轮动物

The small, free-swimming, ciliated aquatic larva of various invertebrates, including certain mollusks and annelids.

担轮动虫多种水生无脊椎动物，体型很小能自由游动的、有纤毛的幼虫，包括某些软体动物和环节动物的幼虫

The 28S rDNA molecular phylogenetic trees showed: 1 entoprocts and phylactolaemate ectoprocts constituted a sister group, strenghthening the opinion that entoprocts should be reunited into phylum Bryozoa; 2 the cheilostome gymnolaemates was obviously non-monophyletic; 3 bryozoans itself was polyphyletic beyond any doubt, its main lineages were scattered in different positions of the lophotrochozoan trees; 4 to our great interests, the phylogenetic position of cheilostomes was between the diploblastic and the triploblastic, indicating they may play an important role during the evolution route from the diplobastic to the triploblastic animals.

28S rDNA分子系统树显示，内肛动物和被唇类外肛动物聚在一起并互为姐妹群，支持将内肛动物重新归入苔藓动物门的结论；唇口目裸唇类外肛动物绝非单系发生；苔藓动物本身也不是单系发生的，其主要类群分别位于触手冠担轮动物系统树的不同位置，特别是，唇口目苔藓动物的系统地位介于二胚层动物和其它三胚层动物之间，可能是二胚层动物向三胚层动物演化过程中的一个关键类群。

Diploblastic cnidarians as the outgroups, the phylogenetic trees of bryozoans and lophotrochozoans were reconstructed by the 28S rDNA analyses of theirs and other related bilaterians obtained through GenBank with different methods, respectively. Meanwhile, the primary and predicted secondary structures of their partial divergent 28S rDNA domains were compared and analysed.

结合GenBank上其他三胚层动物的相关序列数据，以二胚层刺胞动物为外类群，运用遗传分析软件，以不同方法构建了苔藓动物以及触手冠担轮动物的分子系统树；同时绘制了各代表类群28S rDNA的部分多变区的二级结构，并对其形态学特征进行了比较分析。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
