Contrasting with control treatment, the fit of the Exponential distribution in characterizing fine root longevity was elevated under N amendment treatment, at the same time, the distributions of Welibull, Lognormal, and Normal were still better in character. All above indicated that N fertilization treatment maybe only alter the absolute value of longevity frequency, but the ratio between longevity frequencies was the same as before. So the model of longevity was unalterable.(5) Regardless analyzed with whichever categories i.e.
对各生长季细根寿命的统计分布拟合检验的结果与对照相似，施肥仅仅提高了总体分布对细根寿命的拟合优度，但威布尔、正态以及对数正态分布仍然拟合最好，这说明施肥可能仅改变了不同细根寿命频数的绝对值，但各寿命频数间相对比例并未发生明显变化，寿命理论分布的类型保持不变。

Only in cauchy distribution are expected value and variance non-exist. By sas programming with SQL and MACRO we solve the fit of frequency distributions of data with these distributions. Meanwhile good-of-fit test is actualized so that the bound of parameters of distribution function is dwindling until the desired accuracy is arrived. The process is executed by the circle of macro.
利用SAS的SQL和MACRO等语句编写了大量的程序，以拟合优度检验结果为标准，不断地变换八种分布的参数变化范围，通过宏程序的不断循环，逐步缩小参数的范围，最后达到预先设定的标准，从而可以发现八种分布中哪几种分布能比较好地拟合给定的实际频数资料，我们再根据拟合优度检验的结果判断出哪种分布拟合实际频数资料最好，最终获得该频数资料的最佳的理论分布函数形式。

The 1-4 order variation law of frequency, energy and distance of MS events before destabilizing can display the change rule of MS events. According to the variation law of the difference of frequency, energy and distance of micro seismic events before destabilizing, the fracture of rock mass can be precisely predicted. This is of great importance for safety of colliery.
微地震事件的距离、能量、频数的一到四阶差分均能够显示微地震事件的变化规律，根据未失稳岩体微震事件距离、频数、能量差分变化规律，能够准确地利用微震监测技术预报岩体破裂，这对于采用微地震监测技术解决矿山井下岩体破坏失稳预报具有重要指导意义。

P×P and P were two major non-Bayesian algorithms. 6 Less than 25% of the participants used frequency. In those who got other results except P , much more people used probability. Experiment 2 had a randomized multigroup posttest design. There was only one factor named implied condition which had five levels: not imply, imply P, imply addition, imply division and imply all. The results showed that: 1 All the implied conditions significantly improved the participants' performance. When under the condition of implying division, the participants derived the best results. 2 31.9% of the participants got correct answer, 73% of who used frequency to rewrite the information. 3 78% of the participants could apply one or several of the four concepts: probability of "not the event", multiplication rule, addition rule and condition probability.
结果表明：1 被试的估计受问题内容的影响，权威型问题情境容易使被试高估，非权威型问题情境使被试的高估现象大大减少；数据结构和提问形式对被试估计不产生影响。2 有近5%的被试能正确估计P，其中 73%使用频数对信息进行再表征。3 贝叶斯推理中各分步骤的困难程度由低到高分别是：乘法、P、加法、除法。4 有50%的被试能运用对立事件概率、概率乘法、概率加法、条件概率这四个概念中的一种或者几种。5 使用最多的两种非贝叶斯算法是P×P和P。6 不到25%的被试使用频数；求得除P以外各类结果的被试中，使用概率的人数远多于使用频数的。

Nowadays the researches of frequency distribution of data are almost limited to normal distribution, while other distributions are seldom studied. Many frequency distributions of data are not normal. This kinds of frequency distribution of data widely exist. Unimodal frequency distribution of data often occurs.
现在绝大多数关于频数资料分布的研究都是基于正态分布的，而对其他类型的分布研究得比较少，实际上频数分布在许多情况下并非呈现正态分布，分布的形态丰富多彩，很多资料都是呈现单峰分布，本研究就是利用数学上常见的八种连续型变量的分布类型去拟合单峰频数资料。

In the paper only the range of normal value and the description of frequency distribution are discussed. In theory the widely-used percentile method to determine the range of normal value is imperfected. Curve fitting method show some advantage in determining the range of normal value, but is difficult to calculate.
从理论上说明了现在常用的确定正常值范围的方法存在一定的问题，尤其证明了大家使用得比较多的百分位数法存在的缺陷，说明了曲线拟合法的优点，而在频数分布拟合完成之后，就已经找到了频数分布资料的理论分布曲线，有了理论分布函数，我们利用分布函数计算正常值范围就比较容易，也比较准确。

absolute frequency：频数
教师讲解:在记录时,候选人的名字出现的次数有的多,有的少,或者说它们出现的频繁程度不同. 通常,每个对象出现的次数用"划记"的方法累计(例如,1票一划,5票为一"正"). 某个对象出现的次数称为频数(absolute frequency),频数与总次数的比值称为频率(relative frequency)
