The effects of magnitude and distribution of the electromagnetic force on the flow around the aerofoil were investigated. The results show that the electromagnetic force with large magnitude and concentrated distribution on the surface of aerofoil is advantageous to eliminate vortex structures and boundary separation, and therefore to increase the lift-drag ratio.

同时对不同电磁力大小和分布影响翼型表面边界层流动的规律进行了探讨，其结果表明，较大的电磁力和更加集中于翼型表面的电磁力分布可以很好地消除涡结构，抑制边界层分离进而达到提高升阻比的效果。

Anurognathus was a tiny pterosaur that had a short head, pin-like teeth for catching insects, and although it traditionally is ascribed to the long tailed pterosaur group, its tail was comparatively short, allowing it more manoeuvrability for hunting in woodland.

蛙嘴龙是一种体形小巧的翼龙。它的头短短的，牙齿像针一样，利于捕食昆虫。尽管传统上将它归入长尾巴翼龙群，但蛙嘴龙的尾巴相对较短，使其在林丛中捕食更具有灵动性。

Helicopter Design Institute of China Aviation Industry deputy chief designer, AC313 helicopter designer Xu Chaoliang description, AC313 helicopter innovation embodied in the eight key technology breakthroughs: 30 minutes drive to meet the "dry run" security requirements ; fuel system and body structure to meet the anti-crash and lightning safety requirements; driver and passenger seat crashed through the anti-dynamic security testing; body structure, control systems and meet the bird impact rotor system security requirements; airborne equipment to meet the lightning and high strength radiation protection design requirements; cockpit layout to meet the crew emergency evacuation safety requirements; rotor and composite material structure to meet the fatigue assessment based on damage tolerance requirements; mechanical systems to meet the design requirements of high energy rotor burst protection.

中航工业直升机设计研究所副总设计师、AC313直升机总设计师徐朝梁介绍，AC313型直升机的自主创新具体体现在八项关键技术的突破上：传动系统满足30分钟的&干运转&安全性要求；燃油系统和机体结构满足抗坠毁及雷击安全性要求；驾驶员和乘员座椅通过抗坠毁动态安全测试；机体结构、操纵系统及旋翼系统满足鸟撞安全性要求；机载设备满足雷击和高强辐射场防护设计要求；座舱布局满足乘员应急撤离安全性要求；旋翼和复合材料结构满足基于损伤容限疲劳评定要求；机械系统满足高能转子破裂防护设计要求。

The increase in the diffusional deposition was found to occur mainly in the chamber after the vane section when the gas expands and slows down. Therefore, particles have longer residence time to be collected in the chamber by diffusion.

此外发现微粒的扩散损失主要发生於导翼片之后的微粒收集腔体中，因为气流出了导翼片之后速度大幅降低，微粒因而有较长的停留时间由於扩散作用而被收集。

The main impression I got from the museum's displays was that the period was a mixed blessing.

在V的一翼是关于&老上海&的书，另一翼则是关于&新上海&的书。

Boeing's approach, which it declined to discuss, combines flying wing and joined wing attributes.

波音的设计，它拒绝谈论的那个，结合了飞翼和连翼布局的优点。

"This is a very unconventional configuration and we don't understand it nearly as well as we understand the flying wing," Perdzock said. We're attacking it the same way with a scale model and quite a large one at that.

&这是一种非传统的结构，我们就象不理解飞翼一样不理解它&Perdzock说道：通过小尺寸模型和更大一点的模型，我们象攻击飞翼一样的攻击它。

The critical ignition pressure of slot has a relationship with propellant property and structural dimension of slots.

翼槽的临界点燃压强与推进剂本身的燃烧特性和翼槽的结构尺寸有关。

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。
