图表中平均(数)差异显著性检验结果的规范表达
The paper tells the differnce between the calculation scope and the caliber of statistics indexes, the distinction between average index and strength opposite index, the categorizing of statistics index, selection of arithmetic average number and harmonic average number when average number is calculated using opposite number or average number, these problems usually puzzle students.
统计指标的计算范围与口径的差异、平均指标与强度相对指标的区分、统计指标归类、由相对数或平均(数)计算平均(数)时算术平均(数)与调和平均(数)的选择等问题常使学生困惑。
We can classify them to the family of power mean.

On Choice of Weight in Computing Averages from Comparative Measurement;
相对指标计算平均(数)的权数选择问题
To reflect the General level of social economic phenomenon, We often adopt various averages in statistics, such as arithmetic averages, mediate averages, modes and middling averages, using artithmetic averages and mediate averages can explain exactly the central tendenly of social economic phenomenon.
为了反映社会经济现象的一般水平,统计上常常采用各种各样的平均(数),如算术平均(数)、调和平均(数)、众数和中位数。
The expressions of the LS transform of the expected number of departures during the time interval (0, t) are obtained.
对具有多重和单重服务员假期的M／G／1排队系统，进一步分析了其离去过程，得到在（0，t］时间内离去平均(数)的LS变换表达式；证明了在t=0时刻系统中无顾客且服务员也开始休假的条件下，如果服务时间和休假时间均服从负指数分布，则（0，t］时间内离去平均(数)的LS变换表达式在到达率和服务率交换时是不变的：讨论了（0，t］时间内离去平均(数)的渐近展开，给出了便于计算的近似公式，具有重要的应用价值。
But behind these high average numbers,there in fact exist very prominent and increasingly bigger income gaps in the whole province,especially between the cities and the villages,or among themselves.
无论人均GDP、还是人均收入和人均储蓄,浙江在全国都名列前茅,但在高平均(数)的背后,城乡合一、城乡之间、城镇内部和农村内部都存在着事实上不断扩大的、在全国也非常突出的收入差距。
