对数字多用表的直流电压20V量程进行检测,按制造厂规定的办法,由多功能校准器输出10V直流电压加到被校数字多用表,用以检定其20V量程的准确特性,因为多功能校准器输出10V电压非常稳定,当加到被校数字多用表上后,数字多用表指示的电压值保持不变,故记录的读数只有10.0001V。因此,测量结果的A类标准不确定度分量不评定。

One day, though, he came up against a real   45 . A young boy came to town on his holidays. He was known as Waterworks and was a real crybaby.

On saying those words, Waterworks felt so   54  that he finally understood why Charlie was always so happy and cheerful. He realized that he was so used to Charlie’s enthusiasm that he couldn’t help but see the fun   55  of everything.
