This is ncs abnormal . there is evidence of axonal and deymilinating sensory motor polyneuropathy in both lower limbs. what is this problem? please ask i don't understand what say in this report ?

It means that the nerves of the legs are affected by something. The report has to be understood in context with the reason for the test and the findings on examination. Best person to ask is the doc ordering the test for proper interpretation

Do not be reluctant to discuss this test result with the ordering doctor. If acute, emerging over a few weeks or several days would consider Guillain Barre. If chronic, the most likely causes to consider might be diabetes, vitamin deficiencies, leprosy, and many others. You have polyneuropathy, and the underlying cause needs pinpointing.
