截面线

The results show that various blade stacking lines have a great effect on location, strength and scale of passage vortex at cascade exit, moderate positive curved blade and positive leaned blade can decrease energy loss of guide vane cascade.

计算结果表明：导向器叶栅采用不同积叠线形式的叶片，对导向器叶栅出口截面上通道涡的位置、强度和尺度以及能量损失的影响是显著的，采用适度的正弯或正倾斜叶片可降低导向器叶栅的能量损失。

Al-Si alloy wires with uniform cross section and very fine grains could be fabricated stably under the conditions that the interior diameter of nozzle was 0.25-0.5mm, Ar pressure was about 0.4MPa, cooled liquid flowing rate was 400r/min, melt jet flying distance was 5-10mm, melt jet entrance angle was 35°~45° and the melt superheat degree was 100~150℃.

结果表明，在喷嘴直径为0.25~0.5mm、氩气压力为0.4MPa、旋转鼓转速为400r/min、合金液飞行距离为5~10mm、合金液入射角为35°~45°及合金液过热度为100~150℃的条件下，可稳定获得横截面圆整一致、晶粒细小的合金线。

At typical plasma conditions (such as a temperature of 10eV and a density of 0.0016g/cm〓), these autoionization widths are larger than corresponding Doppler and Stark widths by a factor of two or three.

研究了O Ⅲ离子基组态2s〓2p〓和第一激发组态2s2p〓所形成的谱项的内壳层光电离过程，由光电离截面所展现的共振结构，确定了1s-2p内壳层激发态的自电离宽度，结果表明，在某些典型的氧等离子体条件，自电离共振展宽是等离子体中主要的谱线展宽机制。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
