行走

The walking mechanism of push-pull air-cushion vehicle includes two parts: push-pull mechanism and anchoring mechanism, both take hydraulic cylinders as driving components. So this walking mechanism has advantages of lighter weight and higher driving efficiency, it can work on many areas.

推拉式气垫车的行走机构包括推拉机构和抓地锚定机构两部分，它们都是以液压油缸作为驱动元件，通过液压传动实现伸缩动作的，这样既省却了轮式、履带式车辆笨重、复杂的行走机构，又大大提高了气垫车的驱动效率，能够适应各种复杂地表条件。

To study the regular human gaits,the test system based on string displacement sensor and human joint angle measurement instrument are used to measure the motion trajectory of anklebone and the joint angles of lower limb under walking in different road conditions,and the measurement data is analyzed and treated based on human rigidbody model and with data fusion method.Then the gaittrajectories and standphases are gotten under the condition of upstairs,normal walking and downstairs.The result shows that the longest standphase is in upstairs condition,the middle is normal walking and the shortest is downstairs.

为研究人体的步态运动规律，采用基于拉线传感器检测系统和人体关节角度测量装置，对人在不同路况下行走时踝关节运动轨迹和下肢关节角度进行了测量，根据人体下肢刚体模型和数据融合方法对测量结果进行了分析和处理，得到了人在上楼梯、平地行走和下楼梯时的步态轨迹和3种路况下的支撑相；上楼梯时的支撑相最大，平地行走次之，下楼梯最小。

The first astronaut to walk in space, Leonov, and his companion, Beliaiev, began making preparations for the walk as soon as their spaceship was launched.

他们的宇宙飞船一发射，第一位太空行走的宇航员利奥诺夫和他的同伴贝列耶夫就开始为太空行走做准备。

The dynamics and its characteristics in every stage of the biped locomotion cycle were discussed, such as kinetic energy and potential energy distribution and evolvement of the robot.

建立了行走动态的数学模型，并进行了数值仿真，对其行走过程每个阶段的特征进行了论述。

Some Hominina adapted to this challenge by adopting bipedalism: walking on their hind legs.

一些南方古猿采用两足行走适应了这一挑战，用它们的后腿行走。

Also, she was capable of walking on two feet despite living in an area of woodland and forest — a finding that downplays the importance of open grasslands to the evolution of human bipedalism.

此外，虽然生活在森林地区，但艾迪却具备靠两足行走的能力。这一发现削弱了空旷草地对人类进化成二足行走的重要性。

Crompton believes the forest canopy bipedalism shown by orangutans provided the kick-start for routine bipedalism when our ancestors came down from the trees and began living on the ground.

一旦人类祖先被迫适应陆地生活，他们就开始从原来的行走方式——地上移动适应两足行走。

Bring forward new method based on clockwise trend to search next path of outline and method based on counter-clockwise tread to search next path of closed graph after analyzing existing algorithmic. New algorithmic improves on graphic generating efficiency and intelligence of system.

在分析已有算法的基础上，提出基于顺时针行走方向搜索外轮廓下一条路径和基于逆时针行走方向搜索封闭图形下一条路径的算法，改进了以往算法的不足，提高了图形的生成效率和系统的智能化程度。

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。

Right now we can say this is the world's oldest bipedal-an animal walking on two feet and what makes this significant is because what makes us human is walking upright," Latimer said."This new discovery will give us a picture of how our 4-million-year-old ancestors walked upright .

Latimer说：我们现在就能说这是世界上最古老的两足行走动物，其意义在于使人类直立行走，这个新发现将向我们展示400万年前的人类祖先是如何直立行走的。
