您要查找的是不是:
- The air is not rare at low altitudes. 在低纬度地区,空气不会稀薄。
- circle at lower altitudes 在低空盘旋
- They were far more prevalent when aircraft operated at low altitudes. 当飞行器在低空飞行时这是相当普遍的。
- On arrival we will circle for twenty minutes at low altitudes, looking for a U-boat. After twenty minutes we return to base. 一到目的地就低空飞行,寻找潜水艇。二十分钟后返回基地。
- Find out how your diabetes is affected at lower altitudes before attempting prolonged or high treks. 在进行更高或更长时间的爬山之前,最好先搞清楚较低海拔对自己有何影响。
- In colder climates, the snowline on mountains starts lower down, and erosion takes place at lower altitudes. 在更寒冷的气候条件下,山体上雪线的起点较低,而土壤侵蚀往往发生在低纬度地区。
- When one comes to more tractable land at lower altitudes, problems of permanent pasture improvement are not nearly so difficult. 在海拔较低的易于耕作的土地上,改进永久草场的问题并不很困难。
- The radar system allows the aircraft to fly at low altitudes and therefore reach the drop zone undetected. 雷达系统允许飞机在较低高度飞行,然后到达未被发现的空投地区。
- In October of every year, the wind follows a predictable pattern, blowing northerly at higher altitudes and southerly at lower altitudes, allowing for a smooth navigation. 在每年的10月份,风在可以预测的情况下发生,从南北风向在不同维度吹过,非常适合气球导航。
- They strongly responded to SWC and Ta. On the other hand, Rd at low altitudes was higher than that at high altitudes because of the higher air temperature there. 相反,由于空气温度高,低海拔的暗呼吸速率(Rd)比高海拔地区高。
- The line cuts the circle at two points. 一直线与圆相交於两点。
- Habit: gliding and circling at high altitude or low altitude on the ground or surface to capture small insects. 习性: 在高空滑翔及盘旋,或低飞于地面或水面捕捉小昆虫。
- Soil LOC had very significant correlations with soil MBC, TOC, TN and FRB, and its content was obviously higher at higher altitudes than at lower altitudes. 土壤有效碳与微生物量碳、土壤总有机碳、细根生物量、土壤全氮之间呈极显著的相关关系.;高海拔土壤有效碳含量显著高于低海拔土壤
- On 3 July 1944 Katajainen flew in an enemy AA trap pursuing an Il-2M formation at low altitude. 1944年7月3日,卡塔雅南在低空追逐一队伊尔-2M飞机时落入敌人防空火力的陷阱。
- One proposal, rumoured to be under consideration for later this year or early 2008, is to set up "pilot programmes" of open airspace at low altitudes in a few provinces, to test policies. 传说今年底或2008年初会考虑实施一个建议,其中将设置“引导程序”,在几个省份开放低空空域,进行试点。
- At low altitudes they help to cool the Earth by reflecting sunlight away from it.At the high altitudes studied by AIM and TC4, however, they trap radiant heat from below, warming things up. 低端云层能够通过反射阳光而给地球降温,而AIM卫星与TC4工程研究的高端云层却将反射回去的热量阻挡,这样地球也随之升温。
- The ship lay keeled over at low tide. 那艘船因退潮而倾覆。
- When we view a circle at an angle, we see an ellipse. 如果我们斜着看一个圆,我们看到的是椭圆。
- The food should be kept at low temperature. 这种食品应低温保存。
- We dug clams in the flats at low tide. 退潮时我们在浅滩挖蛤蜊。
