安全人机工程学范围内的人体特性参数有( )。

A.人体基本尺寸

B.动态参数

C.人体生物力学参数

D.人体视觉参数

E.人体生理学参数

答案

参考答案:A,B,C,D

解析:与产品设计和操纵机器有关的人体特性参数较多,归纳起来主要有如下4类:
(1)静态参数。静态参数是指人体在静止状态下测得的形态参数,也称人体的基本尺度,如人体高度及各部位长度尺寸等。
(2)动态参数。动态参数是指在人体运动状态下,人体的动作范围,主要包括肢体的活动角度和肢体所能达到的距离等两方面的参数。如手臂、腿脚活动时测得的参数等。
(3)生理学参数。生理学参数主要是指有关的人体各种活动和工作引起的生理变化,反映人在活动和工作时负荷大小的参数,包括人体耗氧量、心脏跳动频率、呼吸频率及人体表面积和体积等。
(4)生物力学参数。主要指人体各部分,如手掌、前臂、上臂、躯干(包括头,颈)、大腿和小腿、脚等出力大小的参数,如握力、拉力、推力、推举力、转动惯量等。

When Sally Ride was ten years old, she had no idea that she would some day grow up to be one of America’s first woman astronauts. In fact, if you had asked her then what wanted to be, she would have said, “ I want to play shortstop for the Los Angeles Dodgers.” Sally collected baseball cards by the boxful, and she knew the name and batting average (击球率)of every player in the National League.

But major league baseball didn’t seem much of a possibility for a girl, even an athletic one like Sally, so her father and mother talked her into taking tennis lessons when she was twelve. At first she hated to trade in her baseball bat for a tennis racket, but it wasn’t long before she started to win tournaments in her new sport. “ Tennis became much more fun when I started winning,” Sally remembers. Soon a row of trophies (奖牌)replaced her box of baseball cards, and tennis star Billie Jean King replaced Dodger shortstop Maury Wills as her sports idol.

Sally first became interested in the space program in 1962 when astronaut John Glenn orbited the earth in his Mercury space capsule. Sally was ten years old at the time, but she remembers the launch and the splashdown (掉落) as if they happened yesterday. The girl who used to memorize batting averages became a space fan. She quickly learned the name of every NASA astronaut(there were only eight of them in 1962), the date of every launch, and the name and number of every spacecraft from Freedom 7 to Skylab 3. She could tell you the speed of light (186,300 miles per second), the distance to the moon (238,860 miles), and the names of the three nearest stars( the Sun, Alpha Centauri, and Barnard’s Star).

By the time she was sixteen, Sally had decided to become an astrophysicist, a scientist who studies space. She had also become a nationally ranked tennis player. She remembers yawning(打哈欠) through an important tennis match on June 20, 1969, after staying up all night to watch Neil Armstrong’s first steps on the moon. Sally lost the match.

As Sally got older, many of her friends started playing professional tennis. Some of them tried to talk her into quitting school to join them on the professional tennis circuit. But Sally said no. “ Black holes are more interesting to me than backhands,” she told them. Now she knows that she made the right choice, but in 1970 Sally had no way of knowing that NASA would open the space program to women.
