The effect of empennage spread on flight attitude was analyzed and validated by flight test data.

针对某型导弹尾翼展开过程对飞行姿态的影响进行了细致地分析，并通过飞行试验数据对分析方法加以验证；最后论证了尾翼展开的不同步性会影响导弹的飞行姿态。

Two methods are used in this paper to analysis the flight dynamic performance for UAV without empennage by qualitative and quantitative analysis. One is calculating two longitudinal modes by linearizing the basic motion equations. The other is three-dimensional flight simulation research with complete motion equations.

文章主要运用了基本运动方程线化进行基本模态计算分析和建立全量方程进行三维虚拟飞行仿真研究两种方法来定量与定性的分析与评估无尾式无人机的飞行动力学特性。

High levels of GDH and LDH activities during flight suggested that both aerobic and anaerobic metabolism happened in flight muscle.

飞行中的粘虫具有极高的有氧代谢能力，也具备一定的无氧代谢能力。

The sensitive nymph instar and sexual differences of wing dimorphism in the brown planthopper, Nilaparvata lugens , were studied, and the developmental differentiations of both the indirect flight muscles and the wing buds in the brown planthopper were observed. Molecular biological studies were performed to amplify the indirect flight muscle specific actin gene.

本文研究了褐飞虱Nilaparvata lugens翅型分化的若虫敏感临界龄期和翅型分化在性别上的差异，观察了褐飞虱间接飞行肌和翅芽发育的分化过程，在此基础上，以扩增、克隆褐飞虱间接飞行肌特异性肌动蛋白基因为目的，做了部分分子生物学工作。

The approach to calculating the gliding angle and flight time of each segment was given.The procedure for approaching the whole glide trajectory was described.Two examples show that the differences in the gliding range and flight time between the approximate solution and the...

文中算例结果表明，该近似求解方法计算得到的滑翔航程和滑翔时间与实际值相差很小，航程误差率约为0.7%，时间误差率约为0.6%，因此该方法在近似小初始滑翔角的长航时远程纵向滑翔飞行时是有效的、可行的，尤其针对航程在地球半圈以上的滑翔飞行轨迹。

During the flight of gyroplanes, the vibration generated from the main rotor, tail rotor and engine will influence the control of the whole flight control system adversely and the sensors will generate false signals possibly.

旋翼飞行器在飞行过程中，由主旋翼、尾翼、发动机等产生的振动，将对整个飞控系统的控制产生很不利的影响，容易使传感器产生错误信号。

In each air man eye, no matter how familiar line, every time flight is brand-new, safety of every time flight is twinkle on the top of head alarm the lamp.

在每一个飞行员眼中，无论多么熟悉的航线，每一次飞行都是全新的，每一次飞行安全都是头顶上闪烁的警灯。

Indeed, between the forms of the leaf-covered monopode first encountered, and this monstrous leg, we recall iconic scenes of flight, common amongst grand Renaissance tableaux, one particularly good example being exemplified in Michelangelo's Last Judgement by the bottom right-hand section, which is known as the Boat of Charon—a fitting allusion because Charon was the boatman who delivered the damned into the mouth of hell from which they were presumably anxious to escape, hence the animated energy brought to their flight.

的确，在先前体验过的叶子覆盖着的独脚和这只巨腿的两种造型中，我们忆起典型的逃离场景构图，是文艺复兴艺术的大型静态画面中常见的，而米开朗琪罗的《最后的审判》右下角所谓&卡戎的冥河之船&那部分就是特别典型的代表范例；这个典故在此极为恰当，因为卡戎就是将被打入地狱的人送往阴府的船夫，他们自然急于逃跑，因此才有这些人物脱逃的激动镜头。

Bomb at any time in the shells fell circumstances, the Taiwan stock market will be currency collapse, a large number of capital flight, a large number of rich, hotshots flight, in Taiwan will be no work to do.

在炮弹炸弹随时会掉下来的情况下，台湾股市汇市将崩溃，大批资金外逃，大批富人、能人外逃，在台湾将没有工作可做。
