A method to treat particle production and annihilation in paricle code is proposed. This method does not directly produce particles and hence can be used with less noise. An example is given for a beat wave accelerator. The density change of 0.06% during one plasma period can seriously affect the excitation of plasma waves. In addition, a new method to economically solve atomic processes is proposed, which can be coupled with particle codes. Finally, the coupling between non-LTE free and bound electrons is analyzed with a simple analytical model and its importance in real systems is pointed out.
