The numerical results show that both air lift force and pitch moment increase with the ratio of the slider's rail height to the air film characteristic height and the air bearing number, and finally reaches to stable value.

比较在不同轴承数下的气浮力和纵倾力矩发现：同一轴承数下，气浮力随气膜特征厚度减小而增加；当磁头槽台高度与气膜特征厚度的比值相同时，气浮力随轴承数增大而逐渐增加直到达到某一值后保持不变；纵倾力矩随轴承数增加而增大到某个最大值后减小。

Combined with the measured data of the supply air flow distribution in the existing air-conditioning vents on the audience's part of the theater, the temperature and velocity distribution are calculated under the design project condition, obtaining that air current organization of the pond place and the gallery under this blast form indeed has many problems, proposing the orbed nozzle in the balcony can be replaced by swirl diffusers vertical vents, and the blast form of the gallery will be changed by under-seat air supply.

结合现场所测的数据对观众厅部分现有空调喷口送风的气流组织做简要的计算和分析，并简要计算了设计工况下速度分布和温度分布，明确该送风形式下的池座和楼座的气流组织的确存在诸多问题，进而针对池座提出用旋流风口代替球形喷口垂直下送，楼座则建议改为坐椅下送风。

One summer only calculates 100 day of use The air conditioning needs to consume the electricity 8000 Yuan, the environmental protection air conditioning only needs to consume the electricity 1000 Yuan, one summer air conditioning uses the electrical bill namely may buy an environmental protection air conditioning\'***pense.

举例如：本工厂产品620－4型环保空调1天开12小时＝6.6度电1天（每小时0.55度电左右），×0.25一度电＝1台环保空调节省1.65元1天的用电量，×365天＝602，25元一年。一个夏天只计算100天使用空调需要耗电8000元，环保空调只需要耗电1000元，一个夏天空调所使用的电费即可以买一台环保空调的费用。
