A reasonable warmer winter indexin the framework of the three equiprobability categories(i.e.warmer,normal and colder categories)is proposed based on the winter temperature data observed at 565 stations in China during 1956-2005,where the IWWI is defined as the ratio of the station number of warmer category over the total number of stations.

利用全国565个台站1956-2005年冬季平均温度资料，将多年温度变化划分为偏暖、偏冷和正常三类等概率气候事件，由此给出了一个新的暖冬指数和暖冬的定义。结果表明：暖冬指数与中国冬季温度的变暖趋势相一致，并表现出显著的年代际变化特征，其变率分别为10%/10a和0.4℃/10a。近50a暖冬事件共计发生13次，其中近85%的暖冬发生在1986年以后。

At the same time we brought forward a simulation of the forward collision warning model with 29dof vehicle model developed by State Key Laboratory of Automobile Dynamic Simulation of JiLin University, simulation showed that the model realized the expecting request. 3、It is the membership function of evaluation index that caused flat effect of some certain index and also because of truncation error of computer that the model can not identify relative safety of safe points and unsafe points.

在对驾驶员最优预瞄加速度模型的研究过程中，发现原有模型模糊决策环节的四个评价指标中由于部分指标采用了分段函数作为隶属函数而导致评价指标的平台效应，进而影响到相对接近度指数出现平台效应，又由于计算机截断误差的存在，导致相对接近度指数无法分辨绝对安全点的相对安全性和绝对危险点的相对安全性。

The fidelities of the system surge periodically from 0 to 1 for the etceteras Bell state at original time when average photon number of two-mode entangled coherent states cavity fields are very small.

对于好腔，若原子初始时刻处于相干保持态，系统保真度呈指数单调衰减；若原子初始时刻处于其余Bell态之一，系统保真度呈指数振荡衰减，且随着腔场初态的平均光子数的增加，系统保真度的振荡频率增大，振幅减小。
