discuss two types of maps on operator spaces. Firstly, through example we show
that there is an isometry on unit sphere of an operator space cannot be
extended to be a complete isometry on the whole operator space. Secondly, we
give a new characterization for complete isometry by the concept of approximate
isometry.</span></span>
