I'm confuse because second time google have disable my adsense account. I can not understand, what's happened. Please help me.
first u tell, what u did to get aprove your adsense a/c when it was first banned? altogether new account or same account was aproved?
This time your account was banned because you created a second account which is not allowed in Adsense.
If your account was disable for the first time, then there are chances that you have used the same tactics again and got disabled. So, check your in-box for the reasons Google Adsense disabled your account and try to avoid the mistakes again
