平均

However, the weighted geometric mean method is simpler than the weighted arithmetic mean method, and the former can keep the reciprocity of the improved judgement matrix without transformation.

理论分析表明：虽然这2种方法都具有收敛性，且均可对一致性较差的判断矩阵进行修正，但加权几何平均法比加权算术平均法简洁，且前者无需通过转换，直接保持了修正后的判断矩阵的互反性。

4资讯素养与电脑网路使用经验中之登入XMS网站次数、常用软体之使用频率、每周平均使用电脑时间、每周平均上网时间及在学校学习资讯相关课程的科目数及学分数、在工作场所学习资讯相关课程之时数有显著相关。

This wave direction may depend on the ratio of length to width of the structure. Therefore, it is necessary to make wave search to decide the most dangerous wave direction. In addition, the vertical displacement and wave bending moment of transverse section in long zero upcrossing period are larger than that in short zero upcrossing period.

另外，平均跨零周期较大时的垂向位移和横剖面波浪弯矩值大于平均跨零周期较小时的值，这时结构谐振峰值对响应的贡献不大，且垂向位移和横剖面弯矩沿浮体长度方向的分布呈现明显的非对称特性。

However, feed efficiency of pigs fed diets containing 1000 and 2000 ppm basic zinc chloride were improved by 4.27 and 5.92 % when compared to those of the control and the ZnO 3000 ppm groups, respectively.

在表3日粮处理组中，断奶仔猪的初重、后重、平均日采食量和平均日增重差异不明显，但是与对照组和3000 ppm氧化锌组分别比较，在试猪中饲喂1000和2000 ppm碱式氯化锌分别提高4.27和5.92%。

The results show that(1)the barrier and passage effects of longitudinal range-gorge break the law of zonal distribution of air temperature in Yunnan,the law of longitudinal distribution of air temperature is obvious and the spatial distribution is very zonally asymmetry;(2)under the effect .

结果表明：(1)纵向岭谷地形的"阻隔—通道"作用，使云南温度的纬向分布规律被破坏，经向分布规律比较明显，空间分布极不均匀；(2)纵向岭谷作用下云南热量地域分布差异显著，南部热量丰富，北部欠缺，西部比东部丰富，河谷地区热量最丰富，滇西北及山区热量最贫乏；(3)6、7月热量最丰沛，1月最为贫乏，春季热量好于秋季；(4)近30 a云南年平均气温有明显的上升趋势，存在明显的7 a、11 a、18 a周期振荡；(5)云南年平均气温具有大范围位相一致的变化趋势及东部冷与西部暖的变化类型。

At postoperative 24 hours, neurological defects were scored in five grades [0 score represent no neural impairments; 1 score: the left posterior limbs displayed decreased muscular tension and attenuated contraction reflex; 2 scores: the left posterior limbs were paralyzed, displaying obvious abduction; 3 scores: rabbit displayed obvious adductive drag with body leant to the opposite side; 4 scores: unable to walk and unconsciousness], rabbits were put to death at postoperative 48 hours, infarctional area and volume were determined and pathological changes was also observed.

术后48 h处死兔，测量梗死灶面积、体积，并制作病理切片观察损伤程度。主要观察指标：兔肢体功能状态，脑梗死灶面积和体积，病理损伤程度。结果：59只兔成功建立起梗死灶，模型成功率为98％。①神经功能缺失评分：56只兔为1或2分，有3只兔达到3分。②梗死灶平均面积为(0.465±0.012)cm2，平均体积为(0.268±0.009)cm3。

Methods Using Aerophone Ⅱ Model 6800 and Visipitch 6097, vital capacity was recorded first , then the simultaneous phonation volume, maximum sustain phonation time,mean airflow rate,sound pressure level and average pitch were recorded in order to induce the relation of phonation and respiration in normal subjects.

方法应用空气动力学方法，使用嗓音功能分析仪(Aerophone ⅡModel 6800)和可视音调仪(Visipitch 6097)，先记录下受试者的肺活量，再嘱受试者在自然舒适的音调和声音强度下，尽可能长地发元音／a：／，同时记录最长发声时间、平均气流率、平均音调、声音强度、发声气容量，从而推断呼吸与发声的关系。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
