科技英语的基本特点
为了了解科技英语的特点,我们先阅读下面一段关于许用应力的课文。
Despite the tests described in Chapters 1l and 12,materials may still fail in service,sometimes with disastrous results (. when the failure occurs in ,ships,etc.). To try to avoid such disastrous occurring,the designer avoids using materials continuously at their maximum allowable stress. This is done by employing a factor of safety.
Unfortunately,increasing the strength of ponent in the interests of safety not only increases the initial material costs,but also the operating costs. For example,the stronger and heavier the structure members of an aircraft,the fewer passengers it can carry and the more fuel it a balance has to be maintained between safety,initial cost and operating designer is constantly striving to improve the former whilst reducing the latter.

Allowable working stress is taken as a proportion of the yield or proof stress;that is,ponent is only stressed within its elastic range when in example, consider the screwed fastening shown in Fig. . When the nut is tightened normally the bolt is stretched slightly and,providing it is stressed within its elastic range,it will behave like a very powerful spring and will pull the joint faces together very firmly.
