It is the first report of an outbreak of 114 food-poisoning cases due to consumption of Penicillium cyclopium contaminated dried persimmon. Gastralgia, diarrhea, dizziness and general malaise are chief symptoms of the poisoning, with incubation period of 2-6 hrs generally and a short disease period (generally recovered within 2-3 days). No entero-pathogenic organism, pathogenic coccus and Campylobacter jejuni were detected. Surface fungi counts were 49,000/g, 21.3 times of that discovered in the marketed dried persimmon. Penicillium cyclopium Westling was the dominant fungus isolated. Mouse toxicity tests were carried out with the crude extracts of the fungus culture. Diarrhea, tremor and convulsion were observed before death. During autopsy, necrosis and hemorrhagic foci were observed in G.I. tract after intra-peritoneal injection and intubation. In histo-pathological examination, different degree of necrosis and scaling of gastro-intestinal mucous membrane, lymphocyte infiltration, and necrosis of liver cells and renal tubule epithelial cells could be seen.

Teleseismic P-wave receiver functions at 20 broadband seismic stations in the Longmenshan fault zone (LMFZ) and its vicinity were extracted, and the crustal thickness and the P- and S-wave velocity ratio were calculated by use of the H-k stacking algorithm. With the results as constraints, the S-wave ve-locity structures beneath each station were determined by the inversion of receiver functions. The crustal structure of the Rear-range zone is similar to that of the Songpan-Garze Block, whereas the velocity structure of the Fore-range zone resembles that of sichuan Basin, implying that the Central Principal Fault of LMFZ is the boundary between the eastern Tibetan Plateau and the Yangtze Block. Lower velocity zone exists in lower crust of the Songpan-Garze Block and the central-southern seg-ment of the Rear-range zone, which facilitates the detachment of the material in upper and middle crust. Joint analysis of the receiver functions and the Bouguer gravity anomalies supports the thesis on the detachment-thrust mode of the LMFZ. A double-detachment pattern is suggested to the tectonic setting in the Songpan-Garze Block. The upper detachment occurs at the depth of 10-15 km, and represents a high-temperature ductile shear zone. There is a lower detachment at the depth of about 30 km, below which the lower crust flow exists in the eastern Tibetan Plateau. Interpretation of the Bouguer gravity anomalies indicates that the sichuan Basin is of higher density in upper and middle crust in compari-son with that of the Songpan-Garze Block. The LMFZ with higher density is the result from the thrusting of the Songpan-Garze Block over the sichuan Basin. In the lower crust, higher P velocity and higher density in the sichuan Basin are related to more rigid material, while lower S velocity and lower density in the Songpan-Garze Block are related to the softened and weakened material. The higher density block beneath the sichuan Basin obstructs the eastward flow of lower crustal ma

International Journal of Sediment Research 1999年第2期14卷 413-417页

作者： LIU Xingnian HE Yueping ZHANG Xiangjing QIN Youzhong CAO Shuyou (State Key Hydraulics Laboratory of High Speed Flows,Sichun Union University,chengdu 610065,P.R.China) (Gongzui Water Power station,sichuan,P.R China (chengdu Staff College of Water Power)

The Gongzui reservoir on the Daduhe Rivet, controlling 98% of the entire river basin. is a major power project in sichuan province. Since 1971, the reservoir has been seriously silted up and lost more than 60% of its total storage capacity and 14% of its regulation storage. The sedimentation in the reservoir has seriously influenced the power output and generators in recent years, and may cause some flood disasters in the upstream of the reservoir Especially, the deposition of coarse particles will endanger the security of Shaping section of Cheng-Kun railway, located at the upstream of this reservoir. The sediment problem is a key challenge for the reservoir management A systematic research is needed to solve the problems. This paper presents recent observation data details of sediment problems and possible sediment disasters in the future. Variation process of the typical cross section from 1977 to 1997, average particle distribution of bed material along the reservoir, the ratio between input and output sediment load, bed load sediment deposition, fluvial process of the delta, and their effects on the regulated storage and the floods in the upstream are discussed in this paper. Three possible programs and their functions for reducing and controlling sedimentation are also proposed.
