The changing of the intensity , frequency , or duration of the pure tone can effect the d ischarge and patterns of the acoustic response of these cortical neurons observed A区神经元的纯音反应与声刺激参数关系密切，纯音刺激的时程、强度和频率都可以影响神经元声反应的放电频数或反应型式。
Logarithm of frequence of every symptom factor was calculated , and then the likelihood possibility ratio of every syndrome , according to which the diagnosis of syndrome was determined 先筛选出15组47项症状因子并求出各症状因子的频数对数，再计算各证候的似然概率，根据似然概率的大小确定中医证候诊断。
There is a distinct relation between autumn rainfall of south part of vietnam and zonal component of wind field , especially the 850hpa zonal component of wind over the tropical pacific . 5 5 .登陆越南的热带气旋频数特征及其与越南降水的关系夏季登陆越南的热带气旋频数年际变化大，最多有5个，最少只有1个。
Calibration typically entails an iterative process that computes coefficients such that the gravity model replicates the trip length frequency distribution and matches base year productions and / or attractions 典型的校准在系数计算中通常有一个迭代过程，好像重力模型复制了出行距离频数分布，同时匹配基年发生和吸引。
But particularly as windows nt has to deal with multimedia , video and audio data types , they are being able to do on - demand scheduling and predict how the resources of the system are being used 但是特别地当窗口新台币必须处理多媒体,录像带和声频数据类型的时候,他们是能够做要求的行程安排而且预知系统的资源如何正被用。
But at present , the management and retrieval of the video data are all generally based on attribute or text describe . because of lacking content grade information , the users are facing a lot of restrictions 然而目前对视频数据的管理、组织和检索一般都是基于属性或文本描述的，由于缺乏内容级信息而使用户查询受到很多限制。
A counter with timing fiducial oscillator acts as a frequency multiplier , and the count value in the prior period is taken as the reference for the current period to give the decimal part of a signal period 该方法利用带基准时基的数字计数器实现周期内线性细分，当前周期信号将前一整周期的倍频数作为参考构成信号周期的小数部分。
For example , it was found at some on - off neurons that the change of the intensity , frequency or duration of the pure tone could result in inhibiting or even disappearing of the on - response or off - response 在部分on - off反应神经元上观察到，当纯音刺激参数改变时，可导致on反应成份或/和off反应放电频数改变，甚至导致反应成份的消失。
The corresponding matrixes of membership degrees are gotten through different membership functions and weight scales of assessment indices are determined by expert judgment method and statistical method of frequency 合理地划分了评价单元并确定了评价指标量化标准，通过不同隶属度函数得到相应的隶属度矩阵，利用专家评判法和频数统计法确定评价指标的权重。
2 ) the appearance frequency of strong ssw event had obvious interannual change . from the 1970s to 1980s it happened frequently , average 1 times per year . but from the 1990s it happened less , 0 . 42 times per year 2 )强ssw事件发生频数存在明显年代际变化，上世纪70年代和80年代为高发阶段，平均发生频数为1 . 0次年， 90年代起为低发阶段，发生频数下降为0 . 42次年。
