It is believed that compared with the heat flow observed on the Earth’s surface, the mantle heat flow gives more information from the depth. In recent years, along with systematical geothermal studies, the mantle heat flow in the North China Basin has been calculated and reported.展开更多

We have observed that a hydrophobic and rigid benzene ring as a spacing group between the main chain and the protein seems to be a dominant factor for the high biologieal activity of the immobilized enzyme. Poly (N-p-methaeryloxybenzoloxy-5-norbornene-2, 3-diearboxhnide)-trypsin [P (MBONB)-try-psin] matrix exhibited a bioactivity around three times that of the poly (N-metha-展开更多

Because comets often are very faint, the observations of them are quite difficult; and in addition, the data on them are scanty. Moreover, no monochromatic photometry has been made on Halley’s comet. On November 6—10,1985, observations of Halley’s comet were made at the Yunnan Observatory, Academia Sinica by using the 1-m (f/13.3) telescope and the CCD (Charge Couple Device) as well as the cometary filters. CCD is a new type of detector. It has a higher quantum efficiency and a wider range of linear response than the photographic plate does.展开更多
