建立了BESIII漂移室的全长原型及其读出电子设备，并进行了波束测试。研究了“单阈值法”和“双阈值法”两种不同的定时测量方法。测试结果表明，BESIII漂移室及其读出电子器件达到了设计要求。与“单阈值法”相比，“双阈值法”具有更好的定时精度和噪声抑制能力。

A full-length prototype of the BESIII drift chamber together with its readout electronics was built and a beam test was performed. Two different methods, namely “single-threshold method” and “double-threshold method” for timing measurement, were studied. Test results show that the BESIII drift chamber and its readout electronics can reach their design specifications. The “double-threshold method” results in a better timing accuracy and noise suppression capabilities as compared with the “single-threshold method”.
