In recent years much attention has been devoted to AgCl emulsion owing to its se-rial advantages and inimitable *** in the research of this emulsion a thorny problem remains unsolved till now,which is the improvement in sensitivity is always accompanied with high fog *** this work 5 nm Ag_(2)S particles were prepared and used as novel sensitizers in AgCl cubic and{100}tabular microcrystal *** novel sensitizer shows an effective sensitizing ability for silver chloride emulsion,and it is superior to the traditional Na_(2)S_(2)O_(3) sensi-tizer because by using it comparatively high sensitivity can be obtained with lower fog *** the above sensitizing problem is going to be effectively *** discover the evolution mechanism of the sensitizer clusters and explain their excellent sensitizing properties,diffuse reflectance spectroscopy(DRS)was used as a probe on the AgCl microcrystal surface.

Ten capsaicin analogues were synthesized and their pungency degrees were determined through Scoville Organoleptic Test. The relationship between the structure and pungency degree of these capsaicin analogues was discussed. Then four of these capsaicin analogues with higher pungency degree were picked out and added to anti-biofouling paints as repellents to study their anti-biofouling performance by shallow sea buoyant raft hung-plate experimentation. The results showed that capsaicin and dihydrocapsaicin exhibited equally good anti-biofouling performance while nordihydrocapsaicin and N-vanillylnonanamide had poor anti-biofouling performance. Experimental results also showed that the paints with only 0.1% capsaicin or dihydrocapsaicin as repellent without any other biocides had also exhibited good anti-biofouling performance, which provided a new idea for developing novel, more environment-friendly and Cu20-free antifouling paints.

Some samples of sea shell animals stuck and multiplied on the bottom (beneath the seawater) coated with antifouling paints were collected at some domestic maritime spaces, and the content of heavy metals was detected through Inductively Coupled Plasma-Mass Spectroscopy. Meanwhile, comparison with sea shell animals was made on market for edible use. It shows that the content of heavy metals in internal organs of these marine animals is very high due to the large amount of copper and zinc con- tained in the antifouling paints, and this also does severely harm to sea environment and ecology. To study and develop the novel antifouling paints without copper(I) oxide is an imperative task which brooks no delay.

The crosslink ability with HCH0 of different components （sub-units） in collagen and gelatin were investigated. We made a series of comparisons between the components. The difference of crosslink ability was discussed. There is no obvious difference between the crosslink ability of α βcomponents in acid soluble collagen and those of the same components in photographic gelatin. The crosslink ability of α2is greater than that of α1: but the crosslink ability of β11is similar to that of β12, and β components have obviously hydroIyzed during crosslink process. This situation happens in components of collagen as well as in components of gelatin.

An attempt was made to establish a chromatographic separation and analysis method for capsaicinoids and their analogues. A series of factors,such as choice of column and eluents, eluent composition,flow rate of eluent and operational temperature were correlated, countereacted and optimized to attain appropriate separation efficiency and finalize the experimentally oprational procedures as a whole, permiting a mixture comprising 8 capsaicinoids including analogues to be separated and Characterized with an allowed deviations and within a period of 36 minutes via 1 test as well.

Ⅰ. INTRODUCTION It is well known that iodide plays an important role in making photographic emulsion of high sensitivity. It is recognized that incorporation of iodide ions into silver bromide changes the grain size distribution, increases the crystal defect of silver halid microcrystals, promotes the latent image formation and produces traps of vacan-
