他把车越开越快，看着车速表上的指针跳到了100公里。

He drove faster , watching the needle flick up to a hundred km .

通过使用系数乘法器，使车速表校验信号在10Hz～9999.9Hz范围内，按0.1Hz分辨率变化。

By using coefficient multiplier , the correcting signals will be in the range of 10 to 9 ? 999.9 ? Hz with a resolution of 0.1 ?

因此，对驾驶者借以了解汽车行驶速度的车速表，其指示值是否准确及指示误差的大小必须加以研究。

So the accuracy and indicatory error of the speedometer must be studied .
