利用正交试验方法安排试验,用正交多项式建立微波辐照改性煤矸石强度回归方程,将大大减少试验的繁琐性和重复性。同时通过试验证明了用这种方便快捷的试验方法得到的微波辐照改性煤矸石主要影响因素与试验结果回归方程具有一定的可靠性。 Using orthogonal test method to arrange the experiment, using orthogonal polynomials to establish the regression equation of microwave irradiation modified coal gangue strength, will greatly reduce the tediousness and repeatability of the test. At the same time, it is proved through experiments that the main influencing factors of coal gangue modified by microwave irradiation obtained by this convenient and convenient test method have certain reliability with the regression equation of test results.
