when use insert command,we can insert 5.3000000000e+01 to table,but when use copy command,we get this:
ERROR:  invalid input syntax for integer: "'5.3000000000e+01'"
CONTEXT:  COPY tdsort_metrics, line 1, column monitor_value: "'5.3000000000e+01'"

any idea?

that number is clearly a floating point number.   INSERT takes expressions, and will cast the float to bigint, COPY doesn't and won't.
