On the basis of the data of two cruises in the Changjiang River mouth during the 'rainy season' ofAugust 1981 and the 'dry season' of November of the same year, this article analyzes the horizontal distribution,the sectional distribution and the diurnal variations of total phosphorus (T. P. ), organic phosphorus (O. P. ) andphosphate (PO4), and at the same time summarizes their distributional patterns. It makes also statistic and correlative analyses on different species of phosphorus, their behaviours and characteristics of cycling process in theChangjiang Estuary.

Based on the analytical expression of the electromagnetic field solution of a helical symmetric dielectric material, the relationship between spectral reflectivity and birefringence of a chiral liquid crystal and the blue shift of the Bragg reflection in the condition of oblique incidence are presented in this paper. The theoretical results indicated that: 1) If birefringence(Δn)of the liquid crystal is greater than 0.2 and the thickness of the liquid crystal layer reaches 3μm, the liquid crystal layer will reflect more than 90% of the incident light; 2)To reflect the whole visible spectrum by Bragg reflection,Δn of the liquid crystals in plane alignment state should exceed 0.6; 3) When the incident beam inclines to 60°from the normal direction, the blue shift of the reflective spectrum will reach to 100 nm. On the other hand, since the Δn of the commercial chiral liquid crystals is not larger than 0.2, to get the entire visible reflective spectrum, it needs to introduce a polymer network into the liquid crystals and make a sagging structure on the surface of substrates. The contribution of the network is to establish random anchorage that makes the pitch varied, hence broadening the Bragg reflection *** random distribution of the sagging structure on the surface substrate is used to induce random screw axes of the chiral liquid crystal, which not only causes a blue shift of Bragg reflection but also further stretches the reflection spectra. Experiments demonstrated that the Bragg reflection spectrum could be broadened from80 nm to more than 120 nm, and the contrast reaches 4:1by introducing both polymer network and sagging structure on the substrate surface cell.

One hundred and seven marine aerosol samples were collected during December 1988 to March 1990, and 3 dry deposition samples, 16 rain samples and 2 Cascade Impacter samples were collected from March to May 1990 at the southeast coast of the Xiamen Island. All the samples were analyzed for SO42-, NO3-, Cl-, Na+ , NH4+, using ion *** results indicate that the concentration of sulfate in marine aerosols over the Xiamen waters appears to be of seasonal variation, in an order of winter > spring > autumn > summer. The mean sulfate concentration lor the total marine aerosol samples over the Xiamen waters is 9. 37 μg/m3, respectively 0. 89 and 8. 48 μg/m3 for the seasalt and non-sea-salt sulfate. The distribution of sulfate shows a bimodal form with a peak in the coarse particle range which is derived from the sea-salt sulfate, and a peak in the fine particle range which is derived from the non-sea-salt sulfate. The total deposition of sulfate to the Xiamen waters is estimated to be 4. 68g/m2 · a, with dry and wet depositions being approximately 2.19 and 2. 49g/m2 · a respectively.

On the basis of mixture theory of concentration of Helland-Hansen (Mao et al, 1964; Helland-Hansen, 1916), this paper takes salinity as a conservative factor in the process of dilution and mixture and selects by relating analysis the bydrological and chemical factors which are closely related to salinity. Then making use of the Q type multi-dimensions cluster analysis, we get the results that the water masses in the western Taiwan Strait include the follying: the coastal water along Fujian, Zhejiang and Guangdong Provinces, the diluted fresh water of Minjiang, Jiulong and Hanjiang Rivers; the mixing water in the Taiwan Strait; upwelling cold/warm water to the northwest of the Taiwan Shoal and the upwelling water to the east of Guangdong. The mixing weter in the Taiwan Strait during spring and summer is composed of a Kuroshio branch, the surface weter of the South China Sea, outal wier along Fujian, Zhejiang and Guangdong Provinces. While in autunm and winter, it is mixed up from Kuroshio branch, the shelf weter in the East China Sea, and the coastal water along Fujian, Zhejiang and Guangdong. There is an obvious seasonal change of growth and decline in these water masses.
