Common Errors Over-simplified Statements Abstract In this paper, reconstruction of many holograms are presented by computer with an analyzed mathematical model. Too brief to inform how the reconstruction of holograms is performed, how the analysis is carried out, and what its results really are, etc. Abstract The author in this paper presents a process of fuel-saving innovation. The process is proved to be effective, and the authors are satisfied with the results. Too general and global Common Errors Monotonous Expression Abstract The influence of the cavity of the operation of hydrogen maser and … are discussed. Some design considerations of … are given. A practical construction …is shown. The method with high precision of … is presented. The measured stability data … are also given. Common Errors Monotonous Expression Abstract In this paper, we obtain the stone theorem in De Morgan algebra, and using this theorem, we give a necessary and sufficient condition that De Morgan becomes Kleene algebra. For proving the above result, we introduce a new quasiboolean ring. Furthermore, we prove the quasi-Boolean ring. Using this result, we get a necessary and sufficient condition that De Morgan algebra becomes Kleene algebra. And finally, we discuss some properties of the quasi-Boolean ring. Common Errors Incomplete Contents Abstract The viscoelastic property of various lubricating oils was measured with the oscillating crystal technique. The relation between the shear relaxation behavior and the molecular structure of the lubricating oils is discussed. Eyring’s theory for viscous flow is used to explain the relaxation behavior from a molecular point of view. Some insight into a procedure for estimating the relaxation time from the molecular structure is presented. The paper aims to present the reaction between the shear relaxation behavior and the molecular structure of the lubricating oils. The viscoelastic property of various lubricating oils was measured with the oscil
