What each instrument is supposed to do, I put the them down orally on tape then I go out and find that instrument. 我把每种配器用嘴模仿出来,录在磁带上,然后就去找那种乐器。
The testing result verified the less relative error of this instrument ( within ± 1%) compared with tape measures, and the expected design index was fulfilled. 通过实验验证,仪器与围尺测量的相对误差在±1%以内,达到了预期设计指标。
