The Triple Ionosphere Photo Meter （TRIPM） is a far ultraviolet nadir-view photometer that is onboard the secondgeneration,polar-orbiting Chinese meteorological satellite Feng-Yun 3E （FY-3E）,which was launched on July 5,*** has three channels,and each is used to measure different types of emissions:（1） 135.6 nm airglow produced by the recombination of the O+ions and electrons in the absence of sunlight （nighttime channel）;（2） 135.6 nm airglow from the OI when sunlight is present （daytime/dusk-dawn 135.6 nm channel）;and （3） Airglow in the N2LBH of the TRIPM （daytime/dusk-dawn N2LBH channel）.FY-3E is a satellite operating in the early morning ***,the data are mostly distributed on the dawndusk side or at times when the solar zenith angle is relatively *** this study,combined with simulation calculations,the data are *** further explore the application value of the data products,a model is used to separate the ionospheric radiative recombination contribution from the thermosphere photoelectron impact excitation contribution in the data from the daytime/dusk-dawn 135.6 nm *** approach not only improves the accuracy of O/N2derived from the 135.6 nm channel and N2LBH channel but also provides the ionospheric 135.6 nm radiance at the same time as the *** results show that the 135.6 nm radiance originating from the combination of O+and electrons extracted from the measurement data exhibits similar equatorial anomaly peak structure characteristics and seasonal variations as the corresponding GPS total electron content （TEC） *** the other hand,the separated 135.6 nm radiance generated from the thermosphere photoelectron collision excitation does not contain radiative recombination contributions;thus,the ionosphere influence is greatly avoided when the O/N2is obtained.

我国"十三五"规划推动健康中国建设的号召,体育产业和体育赛事加速发展,由此带来的体育赛事转播权收益不断增加,体育赛事转播权的纷争日益增多,而相关法律规定不够完善,使得理论界对其定性不清且争议较大。2016年两会关于加强体育赛事节目知识产权保护的提案反映了我国完善体育知识产权的客观需要。采用文献研究结合逻辑分析的形式,从体育赛事转播权的历史发展、权利构成、现存困境、相关判例、域外经验等基本角度展开,最终得到如下结论:体育赛事本身因其特性不能成为著作权法意义上的作品而不受其保护;体育赛事画面受著作权法保护,但其定性影响其权力大小;现行著作权法仅可以在一定范围内给予赛事转播权保护。因此提出,借鉴国外相关立法和司法实践,通过网络监管部门加强监管、司法机关发布司法解释、行政机关规范转播授权程序等方式,使体育赛事转播权得到最大限度的保护。
