周期扰量作用下的墙体热工性能的测试,在技术上是很复杂的,因为制造一个周期扰量是不容易的.然而,制造阶跃扰量是要方便得多.在测得阶跃反应后,可以用理论的方法推算出周期扰量的反应.本文讨论了这一计算的原理和实验研究方法. The testing of wall thermal performance under periodic disturbances is technically complex because it is not easy to create a periodic disturbance, however, it is much more convenient to make a disturbance of the stage After the jump reaction, we can deduce the response of the periodic disturbances by using the theoretical method.This paper discusses the principle of this calculation and the experimental research method.
