It is found that the estimating indexes of heart rate variability of MRR, RMSSD and HRVI etc have different sexual sensitivity. The constant temperature airflow of the simulating natural winds can increase the active level of human's pneumogastric nerves, making human body be flabby, relaxed and comfortable. The result indicates the physiological mechanism of the effect of different winding characteristics on the human thermal comfort.

研究发现MRR、RMSSD和HRVI等心率变异评价指标具有不同的性别敏感性；模拟自然风形式的等温气流吹风作用可提高人体副交感神经的活动水平使人体趋向于松弛、放松、舒适和休息状态，研究结果初步揭示了不同风特性对人体热舒适影响的生理机制。

At this stage sea-level westerlies are strong and zonal in character and they lie poleward of their normal position.

在这一阶段海平面上西风气流很强且属纬向性的，它较正常位置偏向极地(北半球上偏北或南半球偏南)。

English: 103. At this stage sea-level westerlies are strong and zonal in character and they lie poleward of their normal position.

在这一阶段海平面上西风气流很强且属纬向性的，它较正常位置偏向极地（北半球上偏北或南半球偏南）。

At constant viscosity, by increasing the liquid flow rate, the liquid film's velocity is increased; at the same experiment condition, the frequency of the liquid film is same at the same radial direction; the air current has minimum effect on liquid film bottom flow velocity, while it has an obvious effect on liquid film surface flow velocity. The longer the distance between liquid film and the inlet, the lower the pulsatory frequency and longer the wavelength.

在粘度基本不变的情况下，随着液体质量流率的增加，液膜流动速度随之增加；在同一个实验条件下，沿圆管径向各质点的频率基本保持不变；气流场速度对液膜底层流动速度影响很小，对于液膜表面流动速度有着较大的影响；沿液膜流动方向，液膜的脉动速度逐渐增加，脉动频率降低，脉动波长变长，与报道的通过快速摄像得到的液膜发展趋势一致，证实用PDA研究液膜流动是可行的。

The air current organization uses circular drifting on to blow of, the next time wind, then has carried on the wind system and the aqueous system computation, and to the pipeline heat preservation, the equipment reduced chirp quakeproof has also made the simple design and the explanation.

气流组织采用圆形散流器上送风，下回风，然后又利用假定流速法进行了风系统和水系统的水力计算，并对管道的保温、设备的减噪防震也做了简单设计和说明。

However, it develops that the rate of cool in g dur in g the expansion in any practical nozzle is too fast for the recomb in ation to occur.

然而，实际情况是，然后实际喷管里气流膨胀时冷却速度都很快，使分子来不及重新化合。

The second one is a regurgitant cold air around Qilian mountain at about 37°N along the valley topography moves westward.

高原东北部地区的大到暴雨产生时低层600hPa的流场特征是三股气流的辐合，水汽来源有三条。

However, if the fire is extinguished without stopping the flow of gas, an explosive mixture may form, creating a more serious hazard than the fire itself, should reignition occur from the hot surfaces or other sources.

但是，如果火灭了，而气流没有切断的话，可能形成可爆混合物。如果在热的表面或其它来源重新点燃的话，会造成比火自身更严重的危险。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
