您要查找的是不是：
- The result indicates that,U50 is a power function of the relative barometric pressure and the relative air density with considering the additional influence of the absolute humidity. 结果表明:U50是考虑绝对湿度附加影响后相对气压和空气相对密度的幂函数;
- relative air density 相对空气密度
- The drag force decreases as the air density decreases. 当空气密度减小时阻力也减
- It also can raise the dats accuracy to determine the earth air density. 也可提高用于反测地球大气密度的资料的精度.
- Climatic conditions, e.g. max. temperature range, humidity, air density. 气侯情况，如：最大温度范围，湿度，空气密度
- The same period, the Ocean Thermal slow, relatively high temperature, air density changes smaller solipsism relative area of low pressure. 同一时期，海洋散热较慢，温度相对地较高，空气密度变化较小，遂形成相对的低压区。
- As a consequence of this angular velocity, the field of the relative air flow past the airplane is curved. 由于存在角速度，通过飞机的相对气流流场是弯曲的。
- For altitudes in excess of 350,000feet the air density is less than 10 -7 of that at sealevel. 在高度高于350000英尺时，空气密度仅为海平面高度的10－7。
- For altitudes in excess of 350, 000 feet the air density is less than 10 -7 of that at sealevel. 在高度高于350000英尺时,空气密度仅为海平面高度的10-7。
- Even when the pressure stays the same, great changes in air density are caused by changes in temperature. 即使压力不变,气温的变化也能引起空气密度的巨大变化。
- The third unit was placed in a box with a relative air humidity of 65% (without condensate!!!), and we regularly made calls with it for 2 weeks (around 20 minutes a day). 第三个单位被放置在一个箱子内的相对空气湿度为65%25（无冷凝!!!),，我们经常通话，它为2周（约20分钟，每天）。
- Everything else being equal, a cold air column, because of its higher air density, is heavier than a warm air column and thus produces a higher air pressure. 在一般相同情况下,冷空气柱因其密度较高,会比暖空气柱重,因而产生气压较大。
- By using square polynomial regressions,a new method to calculate air density in the technology of increasing the load of transmission lines was engineered analyzed. 文中依据原始数据,利用最小二乘法,对动态提高输电线路输送容量技术中空气密度的计算进行了工程化处理,便于更好的推广和使用。
- There is no magic. These planes will only do this in situations of VERY strong headwind, high air density (low-medium alt and cold places for ex) and low weight. 下面的评论说了，这没啥神奇的，这些飞机飞行的位置都面临非常强的顶风。
- Soil water content, photosynthetic active radiation (PAR), air temperature, relative air humidity, water vapor pressure deficit (VPD) and wind speed were measured at the same time. 结果表明：侧柏在不同月份晴天树干液流速率变化具有明显的昼夜节律性，呈单峰曲线；
- The air in the garden was warm and fragrant. 花园里的空气一片温馨。
- The archers sent their shafts through the air. 弓箭手向空中射出利箭。
- The abdominal CT revealed air density in the anterior perihepatiorspace, extravasation of contrast medium(possibly in stomach level)and dirty mesentery are seen suggestive of hollow organ perforation. 腹部电脑断层扫描显现，在肝脏前方有空气，显影剂外露(可能是从胃出来的)及脏的肠系膜，怀疑有中空的器官穿孔。
- It can decrease the temperature of turbo air, increase air density and charging efficiency, and reach the purpose of improving the power of engines and reducing waste gas emitting. 通过中冷器冷却可降低增压空气温度，从而提高空气密度，提高充气效率，以达到提升发动机功率和降低排放的目的。
- Is our relative strength growing? 我们的相对力量正在增长吗？
