有翼肢的

On an average, 1.1±0.3 and 0.4±0.1 rotifers were hatched from per milliliter sediments of the big and the small basins, respectively. The rotifer species, which was hatched at one incubation pattern from the resting eggs in sediments of both the two basins of the lake and whose density was higher than 20ind/200mL, included Proalides tentaculates , Anuraeopsis fissa , Keratella cochlearis , Brachionus diversicornis , Filinia brachiata and B .

mL的轮虫种类总计有6种，它们是多须伪前翼轮虫、裂痕龟纹轮虫、螺形龟甲轮虫、裂足臂尾轮虫、臂三肢轮虫和萼花臂尾轮虫；其中前三种轮虫为两湖区所共有。

And destruction usually occurs on angle.(2)Around the keyhole, the stress centralizes, column" edge opt to inflects in local.(3)The change of friction coefficients or bolt pretension forces can"t affect the performance of top-and-seat angel connections so much.(4)The parameters of angel influence joints performance greatly.

破坏一般是由于顶角钢上应力过大，形成塑性铰而导致的；(2)柱翼缘在与顶角钢相连的螺栓孔周围，存在应力集中，容易导致局部屈曲；(3)材料抗滑移系数的改变和螺栓预拉力的大小对于节点受力性能的影响并不明显；(4)角钢参数的改变对节点的各项性能影响显著，增加角钢厚度，节点的强度、刚度和延性都能得到明显的提高；增加角钢长度，节点的强度和刚度也有较大的提高，延性则略有下降；(5)柱轴压比过大时，节点的承载力、刚度以及变形能力明显下降；(6)螺栓中心线到角钢肢背距离增大时，节点的强度和刚度有所下降，但延性略有增加。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
