This article takes emphasize on analyzing the characteristic of the operational semantics and the emotional se- mantics by examples,enumerating some excellent models in semantic product design,finding out the shortage,and summing up the best way of the dialectic application between the operational semantics and the emotional semantics.

The crambo in chemical experiment operation was compiled.

A structural operational semantics of VHDL.;

It is shown that our stochastic models can be used to provide a compositional causality-based semantics for IMCA,and a event-based operational semantics is supplied to prove its conincidence with various exiting interleaving proposals.

A formal operational semantics based on abstract machine is presented for the implementation of a subset of single-action signal oriented statements.
