Example Sentences:

	1.	Some analytical expressions of fcps , such as frequency gravity , pulse energy , etc . have been calculated , beginning with the description of pulse electric field . range of the influences of carrier phase is analyzed subsequently , both in the time and frequency domain 从脉冲电场的表达式出发，计算得到几周期脉冲平均频率、脉冲能量等参量的解析表达式，在此基础上，分别从频域和时域分析了载波相位的作用大小和范围。
	2.	The emphasis was put on the main factors affecting its performance , such as : drift of the average frequency of interferometer ; drift of frequency difference of interferometer ; the changes of the interference add - on term of the gaussian beam during the measurement and its effects on the phase changes , as well as the relationship between the changes of the interference add - on term of the gaussian beam during the measurement with the movement of the measurement mirror 对双频激光干涉仪的工作原理进行了理论分析，着重分析了其主要影响因素：双频激光平均频率漂移；双频激光差频漂移；高斯光束干涉附加项在测量过程中的变化及其对相位变化的影响，与测量镜运动引起的程差变化的关系。
	3.	Our treatment shows in the raman effect case , mnls solitons , the same as nls solitons , keeps its energy , initial center and initial phase unchanged . however , the raman effect , not the same as nls solitons . reduces its amplitude , widens its width and under the same conditions , the self - frequency shift of mnls soltions is closer to the result of numerical simulation . in the raman effect together with frequency filters case , mnls solitons , the same as nls solitons , keeps initial center and initial phase unchanged and bandwidth - limited frequency filters can make the mean frequency of mnls soltion stand a steady value at the red side of the initial mean frequency , i . e . suppress the self - frequency shift of mnls soltions . and that , the other physical parameters of mnls soltion last stand a steady value . however under the same conditions , the steady value of the mean frequency of mnls soltions is closer to the initial mean frequency and the result of numerical simulation 有所不同的是， raman效应虽然不改变孤子能量，但会引起孤子峰值的下降和宽度变宽，且在同一条件下， mnls孤子微扰理论得到的自频移比nls孤子微扰理论得到的更接近直接数值计算结果。有限带宽的频率滤波也不引起mnls孤子初始中心、初始位相的改变，选取适当的频率滤波器参数值能使孤子的平均频率稳定在初始平均频率的红侧一稳定值，抑制了自频移，而且孤子的各物理量最后都稳定在一稳定值，这些与nls孤子微扰理论都是类似的。有所不同的是，宽度为飞秒量级下， mnls孤子平均频率的稳定值更接近初始平均频率，更接近数值计算结果。
	4.	Then adjust the parameters of gabor filter using the orientation and average ridge frequency at each pixel to realize adaptive filtering . the unrecoverable region is segmented based on orientation certainty . experimental results show a very good visual enhancement effect 求出每个象素点处的纹线方向和方向一致性，以及纹线的平均频率，用方向和平均频率调节gabor滤波器对每个象素点进行自适应滤波，并利用方向一致性分割出不可恢复区域，实验表明具有很好的增强视觉效果。
