| 摘 要： | 针对汽轮机启停过程中，温度变化范围大，温升率小的特点，提出了一种利用１０倍Ａ／Ｄ转换器测量温升率的方法－测差法，该方法减小了１０位Ａ／Ｄ最化误差的影响，提高了温升率测量的准确度，很好地满足了现场实监测热应力的需要。

| Abstract: | According to the characteristic of the wide range of temperature and the smallness of temperature rise rate (TRR) value, a new measuring method for the TRR with 10 bit A/D converter is given, that is measuring difference method. The method reduces the influence on quantize errors of 10 bit A/D converter and increases the measuring accuracy of the TRR. It shows that measured stress used by the method may satisfy the needs of real time measurement on the spot. |
