在飞行中

The Catskill Mountains Many people see UFOs and report alien encounters in the Catskills. Silent Invasion 1991 - a book by Ellen Crystall - discusses over 100 UFO sightings and encounters in the Pine Bush area - over a 10 year period.

许多人们在Catskills中看见不明飞行物和报告不同的飞碟接触案例。1991的《无声的入侵》-亚伦克里斯托尔的一本书–在Pine Bush区域持续10年时间100以上的不明飞行物目击接触案例和相会中讨论。

Represents hang gliding, paragliding and powered paragliding in South Africa. Provides a flying site guide and insurance cover for visiting pilots, and can put them in contact with local pilots and flying schools.

在南非演示悬挂式滑翔，翼伞和动力翼伞飞行活动，向飞行中的驾驶员提供飞行地点安全指导，并与地方驾驶员和航空飞行学校保持联系。

In flight, enhancing combat survivability and increasing mission effctiveness need not only good flight trajectory command, but also appropriate flight attitude and status of the equipments onboard.

在飞行过程中，增强作战生存性和执行任务的有效性不仅需要控制好飞机的飞行轨迹，而且要求有恰当的飞行姿态、机载设备运行状态。

Klein in 1977 used for the estimation of bias and scale factor errors are firstly analysed in details, a new three-step procedures for compatibility checking and a algorithm to improve the robustness of parameter estimation are given, the disadvantages of klein's model is overcomed.

在飞行试验设计方面，首先详尽地分析了传感器和数据采集系统中可能存在的误差情况及其对参数辨识的影响，系统地进行了飞行试验设计，之后给出了一套飞行实测数据的预处理方法。

In airplane design, structural nonlinearities cannot be avoided. The structuralnonlinearities arise from worn hinges of control surfaces, loose control linkages,material behavior and various other sources. In the flighting, the aerodynamicnonlinearities also cannot be avoided. The aerodynamic nonlinearities can benegligible when the speed of the plan is not very high;but when the speed of the planis supersonic or highly supersonic, it cannot be negligible.

在飞机设计中，结构非线性是不可避免的，结构非线性源于控制其表面的旧铰链，松散的控制器联动装置，材料性能和其它的来源；在飞机的飞行中，气动的非线性也是不可避免的，对于飞行速度不是很高的情况，气动的非线性是可以忽略的，而对于超音速以及超高音速的飞机来说，气动的非线性是不可以忽略的。

Minishing the surplus force is the crux of the loading system.the paper aims at lessening the surplus force and improving the loading system performance.

在仿真系统中，飞行控制系统采用实物，而飞行器在飞行过程中所受的外界作用力则由电液伺服加载系统来提供。

A shell had a tail unit so that it would start spinning in flight. But dispersion was still greater than artillery, and that's why we fired by quadrants and not at specific targets.

火箭弹有一个弹尾单元，因此可以在飞行中旋转，但散布还是比火炮大，因此我们对象限射击，而不对特定的目标。

Especially in the Flight simulation systems, the effects and indications are very important to flight and flight training.

尤其是在飞行仿真系统中，云层的显示效果对于飞行模拟和飞行训练来说是非常重要的。

My heart is sad like a mourning dove that's lost its mate in flight.

我的心悲伤的就像一只在飞行中失去伴侣的悲鸣的鸽子。

My heart is sad like a mourning dove that's lost its mate in flight.

我心里悲伤，就像一只伤感的鸽子，在飞行中失去了伴侣。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
