This paper describes a new type of high-reflectivity-measuringinstrument based on an optical resonant cavity together with a CO_2 laser actingas the light source. To show that the desired precision has been reached,this paperexplains in detail its design and principle, describes its measuring circuit and an-alyses various possible errors affecting the precision and the approach to its im-provement. The device features an optical compensating system,an integrating sphereand a phase-locking amplifying detection circuit,in connexion with a digital com-puter for data processing and controlling. The pyroelectric IR detection componentsused in this instrument are applicable to different wavelengths of radiation rang-ing from 1μ to 1000μ. Thus the reflectivity measurements at other wavelengths solong as the laser source is changed is possible. This device is novel in structure.It can deal with a variety of specimens, including plane, concave and convexmirrors of various sorts. This instrument is self-contained. It performs the measure-ment procedures all by itself. With a reproducibility of better than 10~(-4) and anabsolute precision in the range of 10~(-4) to 4×10~(-4).

The paper describes the blackbody with adjustable temperature at about 500K, which was made in 1980. It is used for the calibration of the IR telescope and IR detection system. The blackbody cavity is heated by single chrome-nickel winding twisted unequally. The baffle and the outside wall are cooled by a small fan. The platinum resistance is used to control and measure the temperature of the cavity with an accuracy of ±0.05. The measurements indicate that the temperature difference in the effective isothermal region of the cavity (length 100 mm) is ±0.5℃, and that the temperature stability in the cavity is within 0.1℃ in the period of 5 hours. The geometric shape, the inside shape and the material of the cavity are considered carefully.

Based on the experimental results of IR detection of the absorbed species and effect of acid-base strength on the catalytic properties,it is shown that the activity and selectivity for catalytic dehydration of propanol-[2] are high at an appropriate acid, and basic strength and a H0,max value. The existance of an adsorbed species (-CH2) on catalyst surface verified by IR measurement, means that the reaction takes place by interactions between OH groups of propanol-[2] and acid centers of the given catalyst surface and between H groups ofβ-C in the reactant and base centers of catalyst.It is possible that the acid-base center synergism enables the given reaction to taske place.
