频数分布

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。

A Draw the cumulative frequency polygon for the distribution.

The thesis analyzed chiefly on on law of physical sign disposition of deficiency of spleen-QI in pedo-eczema.Using pykno-analysis, data has been analyzed. We got 23 physical signs of statistical significance,and had non-conditional logistic regression analysis to them. We got 11 physical signs of great value in pedo-eczema diagnosis,including dim-coloured anthema, athrepsy body, weak pulse, diarrhea , etiolate complexion,light texture of tongue,soft skin, house-wife hand,dim qichi, fissured tongue, bluish tendon in shangen etal.And contrast with former diagnostic criteria of deficiency of spleen-QI published by TCM administration bureau, unearch part of the unnoticed physical signs.

论文着重分析了小儿湿疹脾气虚证的体征分布规律，采用频数分析方法，对数据进行统计学分析，分析出其中具有统计学意义的23项体征，并对其进行非条件性logistic回归分析，得出对小儿湿疹诊断具有重要价值的疹色暗淡，形体消瘦，脉无力，便溏，面色萎黄，舌质淡，尺肤松软，手掌纹理增多，气池暗，裂纹舌，山根青筋等11项体征，并与以往国家局的脾气虚证证候诊断标准对照，从而发掘出部分以往未被重视的体征。

A comparison of the two displaying methods of cooling-load rate distribution, that is, time frequency chart and probability distribution curve, is made.

对时间频数图、概率分布图这两种负荷率分布的表示方法进行了比较。

The cluster analysis of 20 most frequent symptoms was consistent with the frequency analysis in TCM syndrome distribution.

通过对出现频率最高的20个症状进行聚类分析，与频数分析得出的患者中医证候分布结果大体一致。

Results The value of fructosamine from the control group was divided skew distribution data. The value of fructosamine was (1.86±0.23)mmol/L.

结果：正常对照组果糖胺值频数呈正偏态分布，参考范围：(1.86±0.23)mmol/L。

Results There is significant differences between boys and girls in 20-meters-running,standing long jump,and throwing sand bag.In jump touching we have not found gender differences.Four sport event's freqency distribution skewed to the left.In addition,there is relation between four sport events and age,sex,height,and weight.

2 0米跑、立定跳远和投掷沙包，性别间差异有显著性意义，纵跳摸高未发现性别差异；四项运动指标在频数分布中呈正偏态；另外，四项运动指标与年龄、性别、身高和体重相关。

The mostly conclusion is as below: 1 The characteristic analysis of the expressway soil erosion: Expressway soil erosion is different from conventional soil erosion and other soil erosion of exploitation construction project for its 4 outstanding features, including imbalance of soil erosion distribution in time and space; Presenting either threadiness or pinnate distribution in space; The quantity of soil erosion is large;Erosion form is complicated and frequency of causality soil erosion occuring is large.

具体得出的主要结论如下： 1高速公路土壤侵蚀的特征分析公路建设土壤侵蚀区别于传统的土壤侵蚀，与其它开发建设项目中的土壤侵蚀也有所区别，有自己突出的特点，主要表现为时间分布上不平衡；空间上呈线状或羽状分布；土壤侵蚀量大；侵蚀类型复杂，诱发性土壤侵蚀发生频数大4个方面。

We adopted Swales'(1990) CARS model and Nwogu's (1997) 5-step procedure in manually tagging the moves of the RAs in the two corpora and employed Salager-Meyer's (1992) analysis method and Kuo's (1999) method respectively in examining the verb tenses and the first personal pronouns.

我们采用Salager-Meyer的方法和Kuo的方法对研究样本中出现的动词时态和第一人称代词进行频数和分布的统计后，又运用Biber的方法对两个语料库中所有研究样本中动词时态和第一人称代词的频数进行标准化。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
