In order to get the signal of indicating piston position, electronic control system should use corresponding sensor to detecting these three position signal.

This paper analyzes the principles and steps of to determining the piston position of the electric control gasoline engine, introduces the requirements of the installation of the sensors, and expounds the principles of determining the piston position of the straight and V type engines.

Theoretical Study on the Coordination Selectivity between the Metal Cations and Amino Acid and the Active Sites of Nucleic Acid;

An important reason that amylase can achieve its function is it has catalysis domain,which is a very basilic domain,and the function of the catalysis domain mainly depends on catalytic active site.

The interaction between bivalent cations(Mg2+,Ca2+,Zn2+) and active site of imidazole has been studied at the levels of HF and MP2 employing 6-311G basis set using ab initio approach of quantum chemistry.

Study on Active Sites of VMgO Catalysts for OxidativeDehydrogenation of Propane;

The purpose of this paper is to explore the performance of SO_2-NO adsorption on Na_2CO_3/γ-Al_2O_3 sorbent-catalyst by means of experiments in a fixed bed reactor and give a tentative explanation as to the results of the experiments according to the mechanism of active sites *.

Active sites and inactive sites are introduced on a two dimensional square lattice.
