>>why cpu 1 of my system is high use?
That depends on the application which is using the CPU .If it is thread enabled it should use multiple cpus for a job.
In your case the CPU utilisation sounds normal only.

Re: why cpu 1 of my system is high use?
well one cpu is doing most of sys, the others the most of usr - the balance is well.
Why shouldn't system processes be summerized to one cpu?
Only cpu 0 has a high idle ...

Re: why cpu 1 of my system is high use?
Normally this is an application issue.
Many applications "bond" to a cpu and are not aware of hyper threading capabilities or second cpu's. This causes imbalance in cpu use.
It is perfectly normal.
