On the basis of optimal material parameter, a simulated fatigue test was conducted on a Y7 airplane stringer joint. The effects of irradiant parameter on fatigue life was studied.
Only by following her born trait, a woman will be endowed with irradiant beauty when lost in love, housework and rearing.
As an example, the paper then describes a newly developed light pulse irradiant uniformity measurement system and the correction method for its measurement result.
