  4. The resuts showed that the annual average temperature had an increasing trend ; summer, autumn and winter average temperature also had an increasing trend and the amplitude in winter was bigger ; the change of standard deviation and coefficient of variation were acute during winter ; the coefficients was bigger ; the change of standard deviation and coefficient of variation were acute during winter ; the coefficients of skewness were positive value during summer and autumn ; the kurtosis coefficients were bigger during winter

    得出如下結論：和田地區年氣溫有增加的趨勢；夏季、秋季、冬季氣溫也有增加的趨勢且冬季氣溫值增幅較大；標準差及變差系數都是冬季變化較為劇烈；偏度系數在夏季及秋季為正值；峰度系數值在冬季較大。
  5. The formulas for computing mean and deviation of the average consolidation degree of double - layered soil are derived as vertical coefficient of consolidation submitting to gamma distribution. with these formulas, the influence of geotechnical auto - correlation distance to the probability characteristics of consolidation degree is studied. it shows that along with the rising of auto - correlation distance, the sensitivity of probability characteristics of consolidation degree to auto - correlation distance is falling

    當豎向固結系數為gamma分佈時，推導了雙層地基平均固結度均值和方差的計算公式：利用該公式分析了土性自相關距離對平均固結度概率特性的影響，結果顯示，自相關距離越大，平均固結度的概率特性值對自相關距離越不敏感。
  6. In the paper, the main results are brought forth in five aspects as follows : ( 1 ). the analysis of statistics the characteristic indicated that the variation coefficient of the soil nitrogen density of 0 ~ 30cm depth is lower, the variation coefficient is only 3. 6 %, the variation coefficient of the nitrogen density of 0 ~ 100cm depth is much bigger than that the 0 ~ 30cm depth, it is 100 %. based on the second national soil general survey material, the average soil profile depth is 101cm, this is in corresponding with skew normal distribution, its standard deviation is 0. 0192
