Results There were no significant differences in higher-order aberrations (HOA), spherical aberrations (SA) and coma under non-accommodation.

In order to meet the demand of coma measurement accuracy of lithographic tool projection lens,a novel method for measuring coma based on fine overlay error metrology marks is proposed.

It is shown that the symmetry of the spectral response and the coupling efficiency will be deteriorated when the coma appears during the diffraction and imaging.

In general condition,it should be allowed that eccentric error is larger than ±10% of average air-gap,but over-large eccentric value can produce very much unbalanced magnetic pull,and then increase the deflection of motor shaft,thus critical speed is influenced.

By introducing the related psychological research achievements into assets pricing field,it s assumed that investors are finitely rational,that there is a real decision-making deviation,and that it s in the assets pricing model based on investor s psychological deviation that abnormal phenomena in capital market are combined with investor s behavior from dif.

In the process of classroom instruction appraisal,the cognitive deviations of the appraisers affect the appraisal accuracy,and the psychological deviations of the students appraised can also bring inaccuracy.

This paper generally analyzes the causes of students behavior and psychological deviation by investigating students deregulation and primarily discusses the ways of rectifying students behavior and psychological deviation in the process of physical education.
