在飞行中的

Aerodynamical parameters in longitudinal model of a certain type of aeroplane are identified in the paper.

论文研究了利用参数辨识方法确定飞机纵向运动模型参数的问题，在分析飞机特性的基础上选取了飞机纵向小扰动线性运动状态方程和纵向非线性运动方程作为辨识的模型，以某型飞机飞行试验实测数据为例对其进行数据预处理之后辨识了模型中的气动参数。

This paper makes further research on the error,caused by use of a single step or a variable step of Runge Kutta to solve the Euler equation of quaternion method, find that the large error results from cumulated error with single step, and when using the variable step,the cumulative error is less.

结果表明，定步长时有很大的累积误差，单位四元数的"单位"性不能得到满足，而变步长有明显的改观，对一般的飞行模拟状态，都能得到较好的模拟结果，可以在实际中使用。

For example,the spiral arrangement of scale－bract complexes on ovule－bearing pine cones,where the female reproductive organs of conifers are located,is important to the production of airflow patterns that spiral over the cones surfaces,thereby passing airborne pollenfrom one scale to the next.

例如，带有胚珠的松球的鳞苞综合体的螺旋状安排，亦即松柏目植物雌性殖器官的所在位置，对于气流模式的形成与产生殊为重要，而这些气流模式在松球的表现盘旋上升，从而把在空气中飞行的花粉从一个鳞苞传播至下一个鳞苞。

Students selected for the course come from the most highly rated aircrews who have completed their first fleet tour and have accumulated 1,000 or so hours of flight time.

学员的选拔在表现优秀的空勤人员中展开，他们必须经历过一次的舰队部署并且飞行小时数累计达到或相当于1，000小时。

His experiments with young indigo buntings showed not only that the star patterns have to be learned through exposure to the skies at an early stage in life, but individual birds may learn to fixate on different reference stars in the small group of constellations that lie over the pole.

他对靛蓝色的巫鸟雀的幼鸟所作的实验表明，不仅仅是星星的形状需要鸟儿在出生后的幼鸟阶段在空中飞行时学知，即使是长大的鸟也需学会注意极地上空的那一小群星座中的各种不同参照星。

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。

Austrian law is likely to be staggered on the opposite time of the outbreak, at the same time must not be exposed to their own 3 FS before the foundation keep silent in the CD, when read carefully, the faster the first time a big fireball will be to come out, and then run around the pillars to the distance, after all, are the opposite of the skills of flight time, one is able to escape for a while, there can be up and down the terrain map is the best, courage would be more dangerous, but there are Two-base, but also about you, probably is this way, RP is not the risk of poor or less basic.

我还见过3奥法，贼法法，法法骑，贼法骑，这些里面最惧怕的还是贼法骑吧。3奥法很容易就可以错开对面的爆发时间，一定不要把自己同时暴露在3个FS面前，留着根基CD在被沉默的时候，谨慎读条，迅捷在中第一个大火球的时候就要给出来，然后围绕柱子向远方跑，毕竟对面的技能都是有飞行时间的，能躲开一会就是一会，有能上上下下地形的地图是最好的，勇气会比较危险，不过有双根基，也差不多吧，大概就是这个样子，RP不差的话基本危险还是不大的。

The computer simulation of ceramic thermal barrier coating on turbine engine blades during loading process has been conducted.

本文通过在计算机中建立航空发动机叶片的工作环境，进而模拟在飞行状态下叶片表面涂敷的陶瓷热障涂层的受力行为，获得了陶瓷涂层在热气动载荷作用下应力场分布，并得出应力场分布与涂层结构和叶片几何形状及与承受的载荷之间的关系，提出了进一步提高陶瓷热障涂层的使用寿命的途径。

It's painted in the color scheme of "Minsi III", the aircraft flown by top navy ace David McCampbell, who won the Congressional Medal of Honor and shot down 34 Japanese aircraft, including 9 in one morning!

这是画中的色彩设计的& Minsi三&，这架飞机飞行的高级海军王牌大卫McCampbell ，谁赢得了国会荣誉勋章和击落34日飞机，包括9日在一个早晨！

Members of the Royal Marines and the RAF Regiment are also able to apply to join the SFSG, which augments the other special forces units on large-scale missions.

英国皇家海军和皇家空军飞行团的成员也可以加入特殊部队支援小组，旨在在大规模的行动中支援其他单位的特种部队。

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。
