查询词典 profile

The roughness shape of ceramic machining surface is analysed by four kinds of test methods: surface profile, scanning electron microanalyses, bearing ratio curve and profile ratio of peak to valley. Ceramics are machined by"plateau honing"to obtain the plateau property and wearability of machining surface. The machining surfaces own its functional surface.

It shows that the exhaust resistance at the wind blast end reduces obviously, driven by the 800mA/12V small scale draught fan, average exhausting speed reaching above 4m/s, fairly enough to satisfy the air conditioner's demand for new wind volume. Meanwhile, the conic section of the horizontal profile and the linear design of the longitudinal profile of the exhaust end inner cavity and wind shroud for each outlet greatly reduce the flowed out exhaust, effectively lowering the wind blowing feel of the air conditioner user by playing the function of air diffusion.

经过计算和实际测试表明，该装置的送风末端风口阻力明显减小，在800mA/12V小型风机驱动下，出口平均风速可达4m/s以上，足以满足空调对象的新风量要求；同时，横截面采用2次曲线型设计、纵截面采用流线型的送风末端内腔和出口均风罩使气流流出后风速迅速衰减，起到散流器的作用，有效降低了空调对象的吹风感。
