A. Random errors
B. Systematic errors
C. Random & systematic errors
D. Zero errors


参考答案:  A


本题详细解析:
Systematic errors arise due tr3qpi;o+k,j jo faulty instrumentation or consistently bad technique. Averaging repeated measurements will not change a systematic bias. So B & C are incorrect. Zero errors are examples of systematic errors, where a the zero of an instrument is not correctly calibrated. So D is incorrect. Random errors will be sometimes too high and at other times too low – so averaging them will have the effect ok,op+jj; rqi3 f reducing the random error. Hence A is correct.
