Stray Light Analysis of Optical System
Abstract：In this paper,we discuss the techniques of stray light analysis in optical system when the ghost image happens.In the meantime, two different surface theories are given,they can describe surface scattering character ics,which are typical in optical system.The first is correctly accounting for shadowing-masking,which based on mirror-like facets reflection theory,with surface roughness small compare to wavelength.The second is a rigorous theory which is based on vector—perturbation theory.Then,the utility of these two models of stray light calculations is discussed.- 65

The Method of Revising Convex Wheel Curve for Makjng Optimum Image Steady in Zoom Lenses
Abstract：This paper analysed the reason of the optimnm image displcement in zoom lenses,suggested the principle that Gaussian Image displacement produced by revising convex wheel curve compensates for the optimum image displacement,discussed the computing method of the optimum convex wheel curve revisng function.In this way,the optimum image is steady after convex wheel curve is revised.This provided the basts for improving the image quality of zoom lenses.- 46

Investigation on the Properties of Doped Barium Fluoride
Abstract：Pure BaF2 crystal and La.Na.Ce doped BaF2 crystals have been grown to improve the properties of BaF2 crystal.UV transmission spectra,X-ray emission spectra,UV light excitation spectra,radiation hard property and energy spectrum of these crystals have been investigated.We found only 1% La deped BaF2 crystal showed strong suppression on slow component and very slight reduction to fast component and 1% La doped BaF2 crystal had the same radiation resistance as the pure BaF2 in terms of its fast component light output when the radiation doses chauged from 105 rad to 106 rad.We first found 385nmnew excitation peak when La doped BaF2 crystal was excited by UV light.- 40

Investigation of the Scintillation Properties of Doped BaF2 Crystal
Abstract：Doped BaF2 crystals have been grown with LaF3,CeF2,NaF doped in BaF2 and the scintillation properties of the new crystal have been investigated before and after a r irradiation of 60Co source.The radiation resistance of the doped crystal can be up to a dose of 106 rad.Comparing with a pure BaF2 scintillator,it was found that the fast component of the BaF2(La)scintillator was almost no change but its slow component was suppressed to a factor of 3.Furthermore,the scintillation mechanisms and damage mechanisms in BaF2 are discussed.- 41

The Static Characteristics of an Externally Pressuized Gas-iubricated Thrust Bearing with a Vacuum-pocket
Abstract：This paper studies the static characteristics of an externally pressurized gas-lubricated thrust bearing with a vacuum-pocket. Relations between the static characteristics of the bearing and depth of airfilm are summarized when source pressure,vacuum degree,vacuum-pocket radius and distribution-circle radius(on which the orfiles are distributed)are introduced respectively.Depth of air-film regarded as a function of vacuum degree relates with parameters of the vacuum-pipe and the bearing,so as to get the basis of theory for quantitative analysis.- 38
