In real life, the reflexion is to create, with some objects all around, an environment like, sky, ground, cars, people etc...

在现实生活中，反射是来自于周围的物体/环境/天空/地面/车辆/路人之类的东西。

In real life, the reflexion is to create, with some objects all around, an environment like, sky, ground, cars, people etc… For this reason we need to add an environment maps on a sphere in constant.

在现实生活中，反射是来自于周围的物体/环境/天空/地面/车辆/路人之类的东西。所以我们需要对环境球添加constant环境贴图。

System developed by Soyuz Federal Centre of Double Technologies at Dzerginsk; water supply of 2.800 litres carried in two underslung tanks or helicopter can be connected to fire vehicle on ground for unlimited supply; hose boom movable in vertical plane only.

系统开发联盟联邦技术中心在Dzerginsk双，水在两下颌突出坦克进行2.800升供应或直升机可以连接到火上无限供应地面车辆；软管繁荣只在垂直平面移动。

And the frontal technique is adapted to solve the FE equations. The techniques are studied to deal with the large slip frictional contactproblems between a deflectable body with large deformation and a rigid bodywith flat or curved surface.

车辆在行使过程中，会出现多种多样的行驶工况，如驱动、制动及转弯侧偏等等，同时，车辆行驶的路面也是多种多样的，如凹凸不平的障碍路面以及越野行驶中的松软地面等等。

The Ground Controller watches the runways and the taxiways uses ground radar information to ensure that the taxiing aircraft does not cross the active runways or interfere with ground vehicles.

地面管制员通过地面雷达监控跑道和滑行道，以保证地面滑行的飞机不穿越运行中的跑道，不与地面车辆冲突。

Wheel, track and walking wheel are three main kinds of the walking mechanisms on the developed air-cushion vehicles.

目前已开发的气垫车辆所采用的行走机构有轮胎、履带、步行轮等三种，虽然气垫车的垫升机构可以明显降低它们的接地比压从而减少了行驶阻力，但依然存在着行走机构自身重量大，结构复杂以及在软湿地面上的滑转、粘土等一系列问题，另外，限于行走机构的几何尺寸影响，这些车辆的抓地位置仅作用于表层土壤，对于表层土壤含水量严重饱和并且硬底层较深的地面来说，甚至使车辆无法行驶和作业，严重阻碍了气垫车辆的推广应用。

Most of existing air-cushion vehicles are hybrid vehicles, that mains one vehicle consists of a air-cushion platform used to carry and a set of walking mechanism used to provide driving power. Wheel, track and walking wheel are three main kinds of the walking mechanisms on the developed air-cushion vehicles.

气垫车辆具有极低的接地比压值，与其它的特种车辆相比，单位面积上的承载力要大得多，非常适用于松软地域下的低速重载运输，因而逐渐成为车辆软地面行驶的主要研究对象。

Military agencies such as DARPA (Defense Advanced Research Projects Agency) have funded a number of robotics programs using collaborative flocks of helicopters and fixed-wing aircraft, schools of torpedo-shaped underwater gliders, and herds of unmanned ground vehicles.

像国防高级研究项目机构之类的军事机构就已经为许多机器人操控项目提供了研发资金，这些项目的研究方向是直升机与固定羽翼飞机的合作群，鱼雷状的海底滑翔机群，与无人驾驶的地面车辆群。
