Assisted gas such as N2, and air has little effects on the kerf, therefore air should be selected in view of lower cost. Uniform cut kerfs can be achieved with lower cutting speed under certain laser power or higher laser power at a certain cutting speed.

辅助气体N2和空气对上下切缝的影响不大，从经济角度应优先选择空气；为了得到上下均匀一致的切缝，同一激光功率下，切割速度应小些，而同一切割速度下，激光功率应大些。

If the lower off is a sling do not, under any circumstances, lower from the sling itself, add a krab.

如果确保站是一条扁带任何情况都不要从扁带下降，加个钩环再说。

If the lower off is a sling do not, under any circumstances, lower from the sling itself, add a krab.

When laying oven walls, top brick corners shall be aligned according to alignment lines and lower corners according to lower-layer bricks.

砌筑炉墙时，砖的上角依准线找正，下角按下层砖找正。

The two catalysts supported on USY zeolites with surface acid amounts of 626 and 203μmol/g, respectively, showed excellent sulfur tolerance, while the catalysts of higher and lower acid amount showed decreased sulfur tolerance. Energy dispersive spectroscopic analysis proved that the support with a large acid amount adsorbed more sulfur, which might lead to the lower sulfur tolerance of the catalyst.

结果表明硫含量为200μg/g时，载体酸量为626和203μmol/g的两个催化剂的耐硫性最好，而载体酸量更低和更高的催化剂的耐硫性较差，表明载体的酸量太大或太小都不利于催化剂的抗硫性。X射线能量散射分析表明，酸量大时S在酸性位吸附很多，这可能导致催化剂中毒。

The facial artery and the lingual arterysend branches to the lower portion and lower pole.

面动脉主干及舌动脉则主要分布于扁桃体的下部和下极。

Lint yield of fiber mutant was lower since lint percentage or lint index was lower than normal-type cotton TM-1,some of other traits,such as higher seed index,better fiber quality.

纤维突变体的衣分和衣指均较低，这是突变体产量低的主要原因，但突变体籽指较TM-1高。突变体纤维的比强度较差，其他纤维品质指标相对较好。
