More than 2 hours after, the office building opened and allowed people to go back to office to take personal belongings, Sophia and me went back to 29th floor by lift to take my laptop, purse and mobile phone, a security guy accompanied us in the office kept saying "hurry up", I notice the plants on the desk fell down on the floor broken, many crevasse on the wall and parget on the floor

2个多小时之后，办公室所在的大厦终于重新开放，允许大家返回办公室拿个人物品了。我和Sophia乘电梯回到29楼，拿了手提电脑、钱包和手机。陪同我们上去的保安员在办公室里不停地催着"快！快！"我注意到办公桌上的盆栽已经掉在地板上摔破了，墙上有很多裂痕，粉饰落了一地。

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。

Results showed that the grain filling rate were faster in prophase and metaphase of filling stage than anaphase, when the date of average temperature preponderate ranges 27.9℃ to 29.8℃ after heading stage 20d. But when the date of average temperature preponderate ranges 25.2℃ to 25.9℃ after heading stage 20d, the results were reverse.

结果表明：优质食用稻籽粒灌浆后20d日平均温度在27.9￣29.8℃时，籽粒灌浆前、中期速度快，后期速度慢，整精米率相对较低；籽粒灌浆后20d日平均温度在25.2￣25.9℃左右时，籽粒灌浆前、中期速度慢，后期速度快，整精米率相对较高。
