The Studies of VUV Optical Constants of the Thin Films
Abstract：This paper discusses the method of evaluating VUV optical constants of the thin films by the multi-restrained nonlinear equation group. With the help of VUV-ROCP microcomputer programme, we can calculate the VUV optical constants of the thin films and the polarizition degree of incidence light by means of VUV reflectance. Using the programme, based on the reflectance of some samples such as gold, aluminium, platinum and copper prepared by different technology, the VUV optical constants of the thin films were obtained and compared with the data published abroad.- 46

A Discussion of the Radiant Theory of the Cavity-type Blackbody
Abstract：This paper is a review of the theories of cavity radiant sources of the quasi-blaokbodies with the emphasis on the integral equation theory of the cavities, Gouffe theory and De Vos theory, including their developing status. It shows the identity of these theories and their development prospect.- 54

The Errors of Refractive Index in the Automatic Measuring Method
Abstract：The high-accuracy automatic refratometer for wide spectrum is based on the method of vertical incidence and symmentrical refraction. Closed measurement of the three angles of the triple prism was carried on to improve the test accuracy. This paper analyzes the errors produced by the light beam collimateion, the verticality between the collimated beam and the base side of thprism, the angle defference,the angle measuring accuracy and the aiming accuracy, etc. The measured deviation of the index is less than 3?10-6 in visible and infrared spectrum. It shows, by comparision with the method of minimum deviation by the tested data, that the two methods have the same accuracy.- 32

A Study of IR Spectra of Na2O-B2O3-Ta2O5System Glass
Abstract：IR spectra of the Na20-B2O5-Ta205 system glass are studied, The glas structures changing with the B203 and Ta205 contents are analyzed. The experiments indicate that with the decreasing of the proportion value (Na20/B2O5) the groups of[B04] and [B03] in the glass structure decrease and increase,respectively, When the Taz06 contents arise[B04]wi11 increase and the non-bridge oxygen decreases, This shows that the Ta5+ can link with non-bridge oxygen and form glass networks.- 43

A Slow-scan TV Camera Tube and Its Application in Computer Image System
Abstract：In this paper the characteristics of the target in the slowscan TV camera tube are analyzed. The structure and performances of the develo ped tube are introduced. The logest image storage time for PbO and Zn-CdTe vidicon are measured.The frame period of the tube is lOs.When the slow-scan camera system is connected to a computer, characters and static image can be transfered.The cost of this image system is not expensive.- 33

Least Square Filters for the Texture Segmentation
Abstract：Based on the foreknowledge of the textures in a given image a new method for the texture segmentation-Least Square Filters are derived in this paper. The method uses a little filter, the number of which dependents on the number of the textures needed to be analyzed, and each filter enhances, certainly, the texture region related. All of these are convenient for the texture segmentation. The method uses a little memory space and its computation speed is fast.- 22

Improved Study for Power Spectrum Diagnosis of Machine Fault
Abstract：Generally, machine fault can be detected by the characteristic changes of the power spectrum of a sensing signal. How to recognize and quanti-tatively translate these signal changes is, therefore, of great importance,A specific variable defined as the expanding coefficient of spectrum which describes the characteristic changes of power spectrum of the signal, is introduced and the fast algorithm of the variable is discussed,It is highly noise proof with good adaptability and requiring less compu-ting time.- 33

Comprehensive Treatment of the Waste Liquid of the Inclusion Zinc in the Galvanizing Production
Abstract：An integrated technological process of treating the waste liquid of the inclusion zinc has been proposed in this paper.The difficulty of separating zinc and iron is overcomed by using a macromolecular condensation reagent so that the product of the inclusion zinc from the waste liquid is solved and the secondary utilization of the zinc resources may be realized.- 28
