此外，ceh- 16突变后还会影响线虫中一个多巴胺神经元的形成，作者还证明这种异常表型也是和侧线细胞的不对称分裂和Wnt信号通路有关。

When the Al-Mg-Zr-Sc welding wire was used as filling material, the grains of welding seam were refined obviously, and the weld joint was greatly strengthened by forming of fine equiaxial grains layer in fusion zone.

结果表明：采用两种焊丝焊接的Al-Mg-Sc合金薄板的焊接接头强度系数均大于0.9。

When the Al-Mg-Zr-Sc welding wire was used as filling material,the grains of welding seam were refined obviously,and the weld joint was greatly strengthened by forming of fine equiaxial grains layer in fusion zone .

但采用Al-Mg-Zr-Sc合金焊丝为填充材料时，焊缝晶粒组织明显细化，熔合区形成的细小等轴晶层提高了基材与焊缝填充材料的结合力，焊接接头的屈服强度比采用Al-Mg-Zr合金焊丝为填充材料时提高了100 MPa，显著提高了Al-Mg-Sc合金焊接构件的许用强度，因此焊接Al-Mg-Sc板材更宜采用Al-Mg-Sc-Zr焊丝。

Mm. 7.5.3 Requirements for quality of weld joint's surface: a No crack, not fusional, bubble, slag, splash; b Surface of seam of pipeline with design temperature lower than -29℃, stainless steel pipeline and alloy steel pipeline with trend of harden quenching shall be free from undercut.

The surface shall be smooth 7.5.3 焊接接头表面的质量应符合下列要求： 28 SH 3501-2002 a 不得有裂纹，未熔合，气孔，夹渣，飞溅存在； b设计温度低于-29℃的管道，不锈钢和淬硬倾向较大的合金钢管道焊缝表面，不得有咬边现象；其他材质管道焊缝咬边深度不应大于 0.5mm，连续咬边长度不应大于 100mm，且焊缝两侧咬边总长不大于该焊缝全长的 10%； c 焊缝表面不得低于管道表面，焊缝余高Δh 应符合下列要求： 1 100%射线检测焊接接头，其Δh≤1+0.2b1，且不大于 2mm； 2 其余的焊接接头，Δh≤1+0.2b1，且不大于 3mm。

Analysis of double mutants between bro-1(bp133) and several heterochronic mutants showed that the proliferative seam cell division occurred at any stage was defective in bro-1 mutation background.

对bro-1和不同异时基因构成的双突变的细胞谱系分析表明在L2时期以外时期出现的增殖性分裂也可以因为bro-1基因的突变而缺失。
