It is found that generalized geometric programming (GGP) is in fact a special case of generalized convex programming. By selecting a suitable bifunetion and calculating its adjoint function, the dual form of the standard GGP problem is derived. Some duality theorems are also obtained with this point of view. The method used is simpler and more general than what appeared in the literature.

This paper reports on the study on the protozoan community structure of the immersed sediment in the Three-Gorges Area of the Changjiang River. Protozoa observed included 7 phytoflagellates, 12 zooflagellates, 49 amoebae and 16 ciliates. Sarcodina dominated in sediment, ciliates in water. Analysis of species and horizontal density distribution of protozoan in sediment in 28 sampling points reflected the pollution degree of water quality at every site. It was shown that heavy metal contamination in sediment has some effects on the distribution of protozoan species in the Changjiang River.

To investigate the characteristics of cochlear microphonic (CM), summating potential (SP) and compound action potential (CAP) and morphology changes of outer hair cells (OHCs) and inner hair cells (IHCs) after OHCs were selectively damaged by acute cochlear perfusion of cisplatin. Dynamic changes of CM, SP and CAP were recorded from the scala media of the third turn of the guinea pig's cochlea during Cisplatin perfusion into the whole cochlea for 2 hours. The results indicated that after one hour of the perfusion, the amplitude of CM, SP and CAP decreased at stimulus intensity 70 dB SPL, as compared to those examined before perfusion of Cisplatin (the average of CM increased by 3.6 mV at 90 dB SPL, average of SP increased by 1.6 mV at 120 dB SPL, average of CAP increased by 0.23 mV at 90dB SPL). After two hours of perfusion, the amplitude of CM, SP and CAP decreased in all stimulus intensities. The staining of Succinic Dehydrogenase (SDH) was weak in OHCs, while the stain ing of IHCs remained normal. transmission electron microscopic examination of organ of Corti showed varieties of morphological changes in OHCs, such as nucleus chromosome disappear, mitochondria denaturalization and number reduction, while the structure of IHC appeared normal. SDH staining showed normal staining pattern in both IHCs and OHCs when the cochlea was perfused with artificial perilymph for 2 hours. The abnormal augmentation phenomenon of CM and SP may be induced by the abnormal control of Ca++ in IHCs and OHCs. The abnormal augmentation of CAP suggests that the suppression effects of OHCs and efferent neurotransmitter on IHCs and afferent neurotransmitter may be reduced after OHCs damaged.

As a new type of catalysts, great attention has been paid to the study of heteropolyacids （HPA） and their salts iu recent yearst. The physicochemical properties and the catalytic activities of PHA have been examined in our laboratory systematically. In this note the influence of coordinated atoms W and Mo on physicochemical properties of the HPA series, H3PMo12-nWnO40 （n=0—12）, has been studied.
