在飞行中的

Based on matrix disterbance theory, a new numerical calculation method to determine system observability of each state through system observability matrix sin gular value decomposition is proposed. This method is applied in flight trans fer alignment and integrated navigation filter design successfully.

提出了应用系统观测矩阵奇异值分解确定滤波器中各状态变量可观性强弱的一种方法，并在系统的飞行传递对准和组合导航滤波器的设计中得到了成功的应用。

The filling of sky and ground region in the attitude indicator of an aircraft electronic flight instrument system is a time consuming work.

在现代飞机座舱电子飞行仪表系统中，全姿态指示器天地区域的实时填充是个非常费时的工作，但已有算法不管是在填充速度还是硬件可实现性上都存在缺陷。

It was reported that the working status and reliability of the tracking/control system and landing field system have been tested to the full through a series of test flights of Shenzhou spacecraft.

据悉，在我国"神舟"系列飞船飞行试验中，测控通信系统和着陆场系统的工作状态及可靠性已得到充分考验。

In hand-control, many basal actions of flight are emphasized ,such as plane's level flight, diving、 climbing and swerving.

在人工控制中重点讨论了基于键盘控制的飞机平飞、俯冲、爬升和转弯等基本飞行动作。

If they're already in mid-flight, raise a knee slightly into the dog's chest.

如果他们已经在中飞行，提高膝盖轻微到狗的胸部。

So far this reality has limited spaceflight to multistage expendable rockets or the space shuttle, which is assisted by strap-on fuel tanks and solid-fuel boosters that are jettisoned during ascent.

目前为止，这个事实使太空飞行限于多阶段扩张式火箭或是太空梭；后者在上升过程中抛出附加的燃料箱和固体燃料助力器。

It's important to get up and stretch your legs during long flights.

在长途飞行过程中，站起来伸展下双腿是很重要的。

In the speeded up program, the fourth and fifth flights developed the techniques of rendezvous and docking with Agena B as the target.

在加速计划中，第四次和第五次飞行的目标是开发与阿金纳B 会合与对接技术。

The Rudras are sprung from hurricanes and are able to fly even during storms. Their sorcerous might is directed towards destruction and they never pause o study or forge items.

楼陀罗诞生自风暴中，因此即使在风暴下也能继续飞行，他们的魔力为毁灭而生，也从不会停下来用于研究或者铸造物体。

Especially the dynamic characteristic of regulator is an important factor to appraise the capabilities of regulator. Nowadays, the problem of dynamic characteristic of regulator is not raveled out property by the entire world.

其中动态特性是衡量减压器性能的重要因素之一，目前国内外关于箭体减压器动态特性问题理论上都没有得到妥善解决，国内在这方面的理论研究更是十分有限，在实际应用中就曾出现减压器因启动时振动而失效，导致飞行任务失败的故障。

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。
