空气动力

Power-driven heavier-than-air aircraft shall give way to gliders.

重于空气的动力驱动飞机应该给滑翔机让路。

Glider: Nonpowered heavier-than-air craft capable of sustain ed flight.

滑翔器：没有动力能持续飞行的重于空气的航空器。

An R/C helicopter is a heavier-than-air model aircraft that derives all of its lift and horizontal propulsion from a power driven rotor system rotating about a nominally vertical axis.

遥控直升机是一种自重大於空气，且通过一套有互相垂直旋转面的动力旋翼系统来实现升降和平移机动的飞行器模型。

Some of the glider experiments conducted by Otto Lilienthal and slightly later by Octave Chanute were so strikingly successful that it seemed a certainty that someone would certainly succeed in making a powered, controlled, heavier-than-air flight within a decade.

部分的滑翔机实验所进行的奥托利林塔尔和轻微稍后由八度音chanute如此惊人的成功，似乎肯定有人一定会成功地使一动力，控制，加重比空气飞行了十多年。

On April 27th it withdrew an air-quality permit it had issued for a 1,500mw pulverised coal-fired power plant, called Desert Rock, which was to be built on Navajo Nation land in New Mexico.

不过，至少环境保护部一改在布什政府时的角色，正为环保进程竭尽全力。4月27日，EPA收回了之前签发给&沙漠滚石&的空气质量审核书，这是本打算建在新墨西哥那哇左1500MW的、以燃烧煤粉为动力的发电厂。

Working principle: Transport goods in sealed tube by the power of compressing and pumping air.

工作原理：以空气压缩机抽取及压缩空气为动力，在密封的网管中自动传送物品。

To guarantee the color not being contaminated, the automatic clean system was devised based on compressed air or negative pressure. To guarantee the continuity and stability of the supplyinking system, the automatic supplyinking system based on electromagnetic valve and liquid level switch was proposed. To guarantee the continuity and stability of the movement of printed head, velocity blending algorithm was proposed.

采用了基于负压空气为动力的自动清洗系统，以防止颜色不交叉污染；采用基于电磁阀与液位开关控制的自动供墨系统，保证了供墨的连续性和稳定性；采用基于速度矢量混合的加减速算法，保证了喷头移动的平稳和连续。

Living plants enhance the air quality of indoor environments, and also have been

植物能提高室内空气质量，而且还被证明能激发动力。

Living plants enhance the air quality of indoor environments, and also have been shown to induce positive energy.

植物能提高室内空气质量，而且还被证明能激发动力。

Because the automobile applies the brake the braking force which needs to be quite big, and is quite frequent, therefore the automobile applies the brake mainly to use the air compressor and the hydraulic pump energizes, the corresponding braking system respectively is the barometric pressure braking system and the hydraulic brake system; The human body mechanical energy mainly uses in the passenger vehicle in the vehicle arresting gear, the driver draws the hand brake lever or steps on presses the foot pedal dive flap, carries on effectively through the steel wire after the wheel applies the brake in the vehicle, prevents the vehicles stop when the landslide or slides moves.

由于汽车制动所需的制动力比较大且比较频繁，所以汽车制动主要采用空气压缩机和液压泵供能，对应的制动系统分别是气压制动系统和液压制动系统；人体机械能则主要用于轿车的驻车制动装置，驾驶者拉动手制动杆或踩压脚踏制动板，通过钢索对后车轮进行有效的驻车制动，以防止车辆停车时滑坡或溜动。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
