Twice investigations around Hangzhou area show that ^7Be content average in the ground air is 5.9mBq.m^-*** content of ^7Be is the highest in autumn-winter period reaching about 7.7mBq.m^-3,the next is in spring about 6.2mBq.m^-*** is in the early summer about 5.7mBq.m^-3,close to the annual average level;and the lowest in a year is in summer-autumm period with a value about 3.8mBq.m^-*** is a decreasing trend from autumn-winter period to summer-autumn of the next year,which is negatively correlated with the variation of the seasonal rainfall in Hangzhou *** this trend is different from that reported by UNSCEAR:it is the highest in spring and the lowest in the late autumn,which is based only on ^7Be falling down from the ***,the present investigation shows that the seasonal rainfall is the main factor influencing the variation tend of ^7Be content in the air.

We investigate the effect of photons and phonons on Frenkel exciton spectrum. The Hamilto nian for a coupled system of the Frenkel excitons. the photons and the phonons is derived. The phonon-exciton interaction makes the energy band of the Frenkel excitons narrow. The photons and the Frenkel excitons make up Frenkel exciton polaritons which are quasi-particles. The Frenkel exciton polariton spectrum consists of two branches. It is found that the photon-exciton interaction makes the ground energy of the Frenkel excitons increase.

Calanoida copepod, Drepanopus bispinosus occurred in both saline lakes, Burton ( S=40) and Fletcher ( S = 56) in Vestfold Hills, Antarctica. Evident differences between two populations in biology and physiology were observed in September and December, 1984. The population in the Burton lake was denser with stronger body and more tolerant to temperature and salinity than that in the Fletcher Lake, reflecting their possible differences of genetic or nongenetic adaptation. The population in the Burton lake has been adaptated to the lake environment, and the population in the Flethcer Lake is in the acclimatization course in the lake habitat.

Ocean environmental information is very important to supporting the fishermen in fishing and satellite remote sensing technology can provide it in large scale and in near real-time. Ocean fishery locations are always far away beyond the coverage of the satellite data received by a land-based satellite receiving station. A nice idea is to install the satellite ground station on a fishing boat. When the boat moves to a fishery location, the station can receive the satellite data to cover the fishery areas. One satellite remote sensing system was once installed in a fishing boat and served fishing in the North Pacific fishery areas when the boat stayed there. The system can provide some oceanic environmental charts such as sea surface temperature (SST) and relevant derived products which are in most popular use in fishery industry. The accuracy of SST is the most important and affects the performance of the operational system, which is found to be dissatisfactory. Many factors affect the accuracy of SST and it is difficult to increase the accuracy by SST retrieval algorithms and clouds detection technology. A new technology of temperature error control is developed to detect the abnormity of satellite-measured SST. The performance of the technology is evaluated to change the temperature bias from -3.04 to 0.05 ℃ and the root mean square (RMS) from 5.71 to 1.75℃. It is suitable for employing in an operational satellite-measured SST system and improves the performance of the system in fishery applications. The system has been running for 3 a and proved to be very useful in fishing. It can help to locate the candidates of the fishery areas and monitor the typhoon which is very dangerous to the safety of fishing boats.

Abundance of total bacteria, heterotrophic bacteria, coliform and oil degradable bacteria and their relations with salinity and suspended matter in the frontal waters in the Hangzhou Bay are described. The results obtained show that the highest abundances of total bacteria , heterotrophic bacteria are encountered around the front and near the northern shore of the Hangzhou Bay, where a positive correlation ( r =0. 70) between the total bacteria abundance and the total suspended matter (TSM) is persent. Moreover,the abundance of oil degradable bacteria being an indicator of oil pollution, is also high in that region.

Through the analysis of foraminiferal fossils in the cores and the combination with the data of paleomag-netism and 1C ages, seven transgressive strata are recognized in the plains of coastal areas of Zhejiang Province. Among them the upper five ones are compared with the results of the previous study, and the lower two ones are discovered for the first time. The sixth stratum is formed in the shallow-sea environment with a warm climate and water depth of 20 ~ 30 m. and the seventh one is formed in the nearshore environment with a warm climate and water depth of less than 20 m. The distribution, age and paleoenvironment of every transgressive stratum is discussed in this paper.

-The material discussed in this paper is from four cruises which were carried out in May -June, 1986 (spring), July -August, 1987(summer) .October -November, 1988(autumn)and December, 1987(winter)respectively. Identified dinoflagellates were 141 species (including varieties and forms) belonging to 18 *** to the distribution and ecological characteristics of dinoflagellates species, we can divide them into three groups: 1) Hyporhaline-neritic group: they are distributed only in type Ⅲ and typeⅣ water and they perform an evident function indicating continental coast water; 2) Eurythermic-euryhaline group represented by Protoperidinium depressum, Gentium fusus, etc. They are fond of perching in mixing water which character is similar to that of coast water even though they are distributed in different water systems; 3) Hyperthermic-hyperhaline group: on the basis of varying degrees to which they tolerate temperature and salinity, we can divide them into two sub-groups: euryhyperthermic-euryhyperha-line subgroup and stenohyperthermic- stenohyperhaline subgroup. The first subgroup is represented by Pyrocystis pseudoxoctiluca whose adaptability reaction occurred with the changing of hydrographic environment. The second subgroup is tropic oceanic species which can serve as a good indicator for Kuroshio in the East China Sea. Its biological boundary coincides well with the hydrographic boundary of Kuroshio water.
