In this paper  the constitute and overall structure of the system are described. Then  the taper inspecting method and principle of the bore are discussed and theoretically analyzed  and also  the corresponding mathematics model is established. As inner diameter measurement is an important parameter for the taper of small-bore  an inner diameter laser non-contact measuring method is presented based on the structure characteristic of the taper of small-calibre bore  which adopted optoelectronic probe sensitive device (PSD) and laser optical triangulation inspecting principle. And then  the laser probe inner diameter measuring system is designed based them. Moreover  the measuring principle  the project of optical system of this measuring system are illuminated in detail in this article. The accuracy of inspecting system is verified by experiment. The results showed that the measuring error of inspecting system is superior to 0.005  and the inspecting repetition is superior to 0.003. It indicates that the system can fulfill the inspecting accuracy demand for inspecting the taper of the small-calibre bore  and the inspecting method is applicable.   Nonlinear interaction of voluntary breathing and cardiovascular regulation 会议论文 作者:  Wu, G.
