[求助]GWD-27-2 急求NN解答.

GWD-27-Q2:

Electronic computer chips made of tiny silicon wafers now regularly contain millions of electronic switches.  Unfortunately, electronic switches that are this small cannot withstand intense radiation.  Micro-Mechanics plans to produce a chip that, because it uses only microscopic mechanical switches, will be invulnerable to radiation damage.  The switches will, however, be slower than electronic switches and the chip will contain only 12,000 switches.

For there to be a market for Micro-Mechanics’ chip as a result of the apparent advantage described above, each of the following would have to be true EXCEPT:

1. There will be applications in which the speed attainable by an electronic switch is not essential.

2. Switches used on electronic chips that contain only 12,000 switches are more vulnerable to radiation damage than the switches on Micro-Mechanics’ chip will be.

3. There will be applications for computer chips in environments where the chips may have to survive intense radiation.

4. Some devices in which computer chips will be used will have other components that will be able to function during or after exposure to radiation.

5. Manufacturers are able to protect electronic computer chips against exposure to intense radiation, where this protection is necessary.

答案是E . 麻烦各位NN鼎力相助!

感激不尽.

有2种chips Micro-Mechanics’ chip 优点是不怕强辐射.但是速度慢,一种是electronic switches的chip 优点是速度快一点但是怕辐射.

题目要求是支持使用Micro-Mechanics’ chip,那么就要找一些能体现Micro-Mechanics’ chip 优点和electronic switches的chip缺点的例子.但是要选exception的哦!(相当于选支持electronic switches)

A,速度不重要,那么electronic switches没有优势了.

B,装了12,000 switches 后,lectronic switches更容易坏也不行.

C,要求chip能survive intense radiation,体现了Micro-Mechanics’ chip的优势,不行.

D,无关选项.

E,Manufacturer可以让chip免于受radiation的影响.避免electronic switches的缺点.选这一个.

哦.谢谢你的解释.当时对于B一直发愣.没想明白.

2楼解释的非常清晰

一看就明白了

大感谢您…

不错，明白了。

基本同意2楼的观点

不过D似乎不应该是无关选项吧，题目要找不能体现Micro-Mechanics’ chip 优点的选项，如果D是无关，那岂非也属于不能体现Micro-Mechanics’ chip 优点的选项之一

我开始选的是D，不过仔细一想，D说的应该是一些设备用CHIP有其他的组件能够在辐射时发挥作用

这样一看，D应该也是能体现Micro-Mechanics’ chip 的优点的

不知道是8是这么理解的？

大致方向没错，题目要求的是选出不能让 M 公司的芯片有市场的选项。

稍微更正一下 2楼的 B 选项

B、（其他公司生产的）只有12000 switch的芯片比 M 公司的更容易被辐射损害—— M 公司产品有市场的原因，不能选
