Samples of the Cross Flow Fan test

"lay雷竞技 " The more the number of samples to test the data more reliable, at least three. 2000,3000,5000,10000,18000 hour test time can be used as specification. That is the test time point i is 1,2, ... .n, because there is a five-point test point, so n = 5, I = 1,2,3,4,5 a total of five points. Suppose a fan of existing products to the axis of fuel consumption to 50% deemed bad, because fuel consumption to 50% for a long time, it is necessary to seek outside its time difference method. If oil loss curve approaches linearity, fuel consumption formula can be written as Y = Ax + b.
