Special structures for coherent FBG group and fiber MZI sensors are designed. For weak signals or strongly interferenced signals, winding method, flat layout method, special coated fiber method or spring separation method, solid separation method are proposed, and the recognition ability for object signals is improved. The physical features of the object signals are extracted from various aspects by the parameters analysis such as maximum amplitude, RMS, ringing count, pulse count, event count and duration, by the waveform transform analysis such as Fourier analysis, AR spectrum analysis and joint-time-frequency analysis, and by statistic analysis of the parameters analysis results or waveform transform analysis results. And the features of different object signals are extracted when the optical fiber sensing systems are applied for railway location, axel counter, fence destruction monitoring and pipe destruction monitoring. Auto-recognition of the railway location signals with coherent FBG sensing system is realized by a linear discrimination function based on Fisher criterion. And auto-recognition of the fence destruction signals with a MZI sensing system demodulated by a 3×3 coupler is realized by a LMBP neural network.

The resulting filings were then placed into an hourglass, making them a testament to time. Marx's concept of necessary labor time is a kind of abstracted duration of labor, a rather idealized concept, and Wang Sishun has taken this classic political-economic concept and paralleled it into a specific production process, which has given it a subtle undertone of the farcical.

By virtue of numerical and analytical method, we got the following results. With the increasing of patch temperature, it is found that (1) the mean open rate of sodium and potassium channels of the HH neuron are decreased, and the mean duration of spikes of membrane potential is also decreased, which are qualitatively consistent with previous experimental results of single ion channel.(2) Under moderate patch size, the mean inter-spike interval of membrane potential first decreases, reach a minimum, and then increases with the increasing of patch temperature.(3) By defining a measure parameterβ, we show that there is a maximal region for the measureβin the patch temperature and patch size parameter plane where the coherence resonance phenomena are very remarkable, and the characteristic time of the output also confirm our result.
其次，在随机的HH模型中，考虑神经元膜上离子通道的随机开关同时受到电压和温度的调控，用数值计算和半理论推导的方法模拟了系统的演化，得到了以下结果：(1)随着温度的增加，HH神经元上的K~+和Na~+通道的平均打开率降低，膜电压脉冲的持续时间也降低，这与单离子通道的实验研究结果定性符合；(2)在膜面积为中等大小时，随着温度的增加，平均脉冲间间隔先降低，达到一个最小值，然后再随温度升高，暗示了存在一个最佳的温度，使系统的输出最有序；(3)通过定义一个相干共振的测量参数β，发现在膜面积和温度的参数平面上，β的取值有一个最大的区域，对应系统的相干共振状态。
