Materials and methods:Male Sprague—Dawley rats were randomly divided into four groups as follow:Normoxia sedentary group,Hypoxic exposure group,Normoxia exercise group,living high training low group.the normoxia sedentary group lived in normoxic environment,hypoxic exposure group made hypoxic exposure for 12h in normobaric hypoxic tent(oxygen concentration 13.6%),Normoxia exercise group took 1h endurance exercise in normoxic environment at daytime,Hiho group was exposured in hypoxia at night after trained at daytime,the mode and duration of the both load were identical to hypoxic exposure group and normoxia exercise group.

研究方法：以雄性SD大鼠为研究对象，分成4组：常氧安静组、低氧暴露组、常氧运动组、高住低训组。常氧安静组在常氧环境下安静生活，低氧暴露组每晚在常压低氧(氧浓度13.6%)帐篷中低氧暴露12h，常氧运动组白天在常氧环境中进行耐力运动1h，高住低训组运动和低氧暴露的方式和时间分别同常氧运动组和低氧暴露组。

The discovery of annual density bands of mass coral skeleton had a profound effect on coral paleoclimatology, and many patterns of density bands have been revealed throughout the global tropic ocean since then. At the first stage, people tended to explore the control factors of density changes from the environment where the coral grows, but they did not succeed. Since later part of 1980s, some researchers have focused on the skeletal architecture and integrated the signals of both environment condition and skeleton density bands to reveal the mechanism of skeleton density changes, and finally a model of skeleton growth was developed which can explain the almost existed patterns of skeleton density changes.

块状珊瑚骨骼密度条带年周期的发现对后来的珊瑚古气候研究产生了深远的影响，随后又发现世界各热带海域的珊瑚存在多种多样的骨骼密度变化模式，起先常从珊瑚的生长环境中寻找骨骼密度变化的控制因素，但是没有成功，从80年代后期，部分学者试图从珊瑚骨骼构架本身出发、综合考虑环境因素和骨骼密度条带之间的关系来探求骨骼密度变化的机理，并提出了一个可以解释大多数块状珊瑚骨骼密度条带变化模式的骨骼生长模型。

Based on the analysis of the Doppler effect of the mobile channel, the performance of two MIMO-OFDM systems (STTC-OFDM and SFBC-OFDM) in the fast-moving environment is studied. Then, the algorithm for channel estimation based on the training sequence is extended into the fast-moving environment by introducing the space-frequency coding, the method of the equal-interval pectinate pilot-inserting, and the complete Maximum-Likelihood space-frequency decoding.

针对快速移动环境中存在的多普勒效应，研究了两种多输入多输出正交频分复用系统在快衰落信道中的误码性能，采用空频编码梳状等间隔导频插入方式，以及完全最大似然空频分组码解码算法，使用导频与接收信号进行信道参数估计，将一般多输入多输出正交频分复用系统中的基于训练序列的最小均方误差信道估计算法推广到了快衰落信道环境中。
