The mites found in stored food and house comprise a large group of subclass Acari, belonging to the suborder Acardida of the order Acarifornes. They can be found in dust and vacuum samples from floors, furniture, mattresses, Chinese herbal medicine, dry fruit, grain, flour, sugar, and bedding. These mites are nidicolous and feed on organic debris, including sloughed human skin, fungi, spilled food, pollen, etc. These mites are particularly prevalent in Chinese herbal medicine, dry fruit, grain, flour, sugar, beds, though carpeted floors near beds or couches may also have large numbers. The most common species are Acarus siro, Tyrophagus putrescentiae , Dermatophagoides farinae , D . pteronyssinus, Glycyphagus domesticus, G. Ornatus, Carpoglyphus lactis and Tarsonemus granarius, etc. The viability of mites in storage is quite strong and they can invade and parasitize the intestines of humans[1 -15]. They can cause pulmonary acariasis[16-25] , urinary acariasis[26-33] and so on. The dejecta of mites is a quite strong allergen and can cause different allergic diseases[34-44]. Intestinal acariasis can be caused by some mites related to the way of diet intake and invading against intestinal mucosa, intestinal muscle[45-5a]. The first report of intestinal acariasis caused by these mites was made by Hinman et al (1934)[45]. From then on, all kinds of studies on the disease have been reported gradually. In order to make an epidemiological survey of intestinal acariasis the investigation of the disease was taken in some areas of Anhui Province from 1989 to 1996.

The kinetics of volatilization of SnS from Sn-Fe mattes was investigatd by using a unique experimental method. A water model test was also carried out for the proper interpretation of the experimental results. It has been demonstrated that the volatilization process displays the first order kinetics with respect to the concentration of SnS in the matte. The process is controlled by the mass transport of SnS in gas phase. The apparent activation energy for the process is found to be 127.4 kj/mol. The effect of temperature and carrier gas flow rate on the reaction rate is discussed in accordance with the mathematical model developed.

The forces of random wave plus current acting on a simplified offshore platform (jacket) model have been studied numerically and experimentally. The numerical results are in good agreement with experiments. The mean force can be approximated as a function of equivalent velocity parameter and the root-mean-square force as a function of equivalent significant wave height parameter.

The chromatographic behaviors of several uronic acid-containing polysaccharides and neutral polysaccharides were investigated in HPGPC for the first time. The effects of sample concentration and ionic strength of mobile phase on retention time were studied. The mechanism for the effects on Mw determination results of polysaccharides by HPGPC was also discussed.
