On September 20 th, 2015, twenty satellites were successfully deployed into a near-polar circular orbit at 520 km altitude by the Chinese CZ-6 test rocket, which was launched from the Tai Yuan Satellite Launch Center. Among these satellites, a set of 4 Cube Sats conform the atmospheric density detection and precise orbit determination(APOD) mission, which is projected for atmospheric density estimation from in-situ detection and precise orbit products. The APOD satellites are manufactured by China Spacesat Co. Ltd. and the payload instruments include an atmospheric density detector(ADD), a dual-frequency dualmode global navigation satellite system(GNSS) receiver(GPS and Beidou), a satellite laser ranging(SLR) reflector, and an S/Xband very long baseline interferometry(VLBI) beacon. In this paper, we compare the GNSS precise orbit products with colocated SLR observations, and the 3 D orbit accuracy shows better than 10 cm RMS. These results reveal the great potential of the onboard micro-electro-mechanical system(MEMS) GNSS receiver. After calibrating ADD density estimates with precise orbit products, the accuracy of our density products can reach about 10% with respect to the background density. Density estimates from APOD are of a great importance for scientific studies on upper atmosphere variations and useful for model data assimilation.

Acta Oceanologica Sinica 2011年第4期30卷 24-32页

作者： WANG liping ZHANG Jianfang li yongping ZHANG Yufang College of Mathematical Science Ocean University of China Qingdao 266071 China Shanghai Typhoon Institute Shanghai 200030 China

A typhoon leading is an important natural disaster to many disasters to China. A giant wave caused by it has brought large threat for an offshore project. Based on the maximum entropy principle,one new model which has 4 undetermined parameters is constructed,which is called the discrete maximum entropy probabilistic model. In practical applications,the design wave height is considered as soon as possible in a typhoon affected sea areas,the result fits the observed data well. Further more this model does not have the priority compared with other distributions as Poisson distribution. The model provides a theoretical basis for the engineering design more reasonable when considering typhoon factors comprehensively.

Purpose: To report the clinical features, therapeutic method, and histopathological findings of a case of mucoepidermoid carcinoma in the lower eyelid and review the literature about the mucoepidermoid carcinoma arising from the ***: Case report and review of the ***: An 88-year-old man developed a painless, indurated nodule in the left lower eyelid for two years and ulceration of the skin existed for a year. He underwent tumor resection and reconstruction of the eyelid. By histopathology, tumor cells showed an admixture of epidermoid and mucus-secreting cells, which was consistent with mucoepidermoid carcinoma. Mucoepidermoid carcinoma is a common malignant tumor of the salivary glands, but rare in the eye tissues among which conjunctiva and lacrimal gland are most commonly involved. It has a higher degree of malignancy than basal cell carcinoma and squamous cell carcinoma. It displays an unusual capacity of aggressive local invasion and recurs easily after simple excision and tumors may require enucleation or exenteration because of the involvement of the intraocular structures and/or *** follow-up is necessary for the patient after ***: Mucoepidermoid carcinoma arising from the eye is rare and has a high degree of malignancy. It should be differentiated from other neoplasms such as basal cell carcinoma and squamous cell carcinoma.

This study presented a simulation-based two-stage interval-stochastic programming （STIP） model to support water resources management in the Kaidu-Konqi watershed in Northwest China. The modeling system coupled a distributed hydrological model with an interval two-stage stochastic programing （ITSP）. The distributed hydrological model was used for establishing a rainfall-runoff forecast system, while random parameters were pro- vided by the statistical analysis of simulation outcomes water resources management planning in Kaidu-Konqi The developed STIP model was applied to a real case of watershed, where three scenarios with different water re- sources management policies were analyzed. The results indicated that water shortage mainly occurred in agri- culture, ecology and forestry sectors. In comparison, the water demand from municipality, industry and stock- breeding sectors can be satisfied due to their lower consumptions and higher economic values. Different policies for ecological water allocation can result in varied system benefits, and can help to identify desired water allocation plans with a maximum economic benefit and a minimum risk of system disruption under uncertainty.
