平均值

Results Psychometry revealed that in PD group the scores of every tests in verbal part were significantly lower than that in control group,and the average value of performance QI was less than that of verbal IQ in PD group.There was no correlation between the course of PD with the scores of every test,whereas motor dysfunction had negative correlations with the scores of every test.The duration of education had close relation with knowledge,apperception,similarity,vocabulary and the aptitude of figure filling-in.

结果 PD组言语部分各分测验成绩均显著低于对照组；PD组操作智商的平均值低于言语智商的平均值；PD组患者病程与各分测验无相关关系，运动功能障碍与各分测验有负相关关系，受教育年限与知识、领悟、相似性、词汇、填图有密切相关关系。

The SNR of brain white matter and the background standard deviation were measured within ROI,which cov ered a large homogeneous area of white matter.The mean pixel values were recorde d within the ROI which was positioned of the head of the femur.

设定兴趣区，并测定脑白质均匀区域的信噪比及背景的标准差，以及以盆腔股骨头为ROI，记录ROI的平均值，交替测量肌肉区域的平均值及背景的标准差。

It appears that the relationships between the land surface heat fluxes and the heterogeneous length scale are significant, but the mesoscale heat fluxes don't indicate similar relationships with heterogeneous length scale. The representability of gridcell averaged surface fluxes is good but that of mesoscale fluxes is not so good.

这些结果表明地表水、热通量的空间分布尺度与非均匀尺度之间存在较好的对应关系，而中尺度水、热通量与非均匀尺度的关系并不明显，说明地表水、热通量的网格平均值的代表性较好，但是不能反映次网格脉动的影响，而中尺度通量的网格平均值的代表性较差。

Theδ~(13)C of Robinia pseudoacacia and Fraxinus chinesis were gone beyond the range of C_3 plants,and the averageδ~(13)C of 7 trees under 720μmol·mol~(-1)CO_2 were higher than the average of C_3 plants,which is 27.0‰.

针叶树的叶δ~(13)C值高于阔叶树，叶δ~(13)C值明显小于枝条和根系的，刺槐和白蜡的δ~(13)C值超出了全球C_3植物的δ~(13)C值的极限范围，720μmol·mol~(-1)CO_2所有树种的平均值远高于C_3植物的平均值27.0‰。

For the sample as a whole, mean and median values calculated from public companies are significantly lower than private company means and medians.

从样本整体来看，上市公司中计算出的平均值和中间值显著低于私营企业的平均值和中间值。

Acquired conclusion was that the sample mean value submitted to normal distribution, and the sample variance was composed of a number of linear sum of random variable submitted to Chi-Squared distr.

得出的结论是：样本均值服从正态分布，样本方差由若干个服从卡方分布的随机变量的线性之和组成；样本均值的期望等于各管落点期望的算术平均值，方差为各管方差的算术平均值；样本方差是各管落点总体平均方差的无偏估计，方差与各管落点散布的差异相关；样本均值与方差相互独立的充要条件是：各管落点属于独立同分布样本。

Moreover, all mean condition factors of the saury in the 6 size-classes of Taiwan were significantly larger than those in the Small-and-Medium (0.421±0.018) and Large (0.449±0.023) size-classes from 1953 to 1989 in Japan.

此外，所有这六种台湾缷鱼规格的秋刀鱼肥满度平均值，均大於日本自1953至1989年间的中小型鱼(0.421±0.018)与大型鱼(0.449±0.023)平均值。

With the system, in vivo experiments were performed and the result proved the validity and feasibility of this approach. The result can be presented like this: the mean WSR value of common carotid artery from healthy adults is between 150~350s-1, and the max WSR value is between 450~750s-1; with comparing the WSR value from a male who is suffering from the internal carotid artery straitness with the natural range of WSR, a phenomenon was found that his max and mean WSR value are both smaller than the natural value evidently.

并且利用该系统进行了大量的在体实验研究，得到了相应的结果并验证了该方法的有效性及可行性，该结果显示：健康成年人的颈总动脉的血管壁剪切率平均值范围为150~350s-1，最大值范围为450~750 s-1；将患有颈内动脉狭窄的患者的血管壁剪切率与正常范围比较发现，其血管壁剪切率的最大值及平均值均显著小于正常范围。

The superior limit of the bulging degree in male is 2.8mm and the mean value is 1.51mm.

对隆起型肺动脉段的突度测量，女性平均值1.51mm，上限值2.6mm，男性平均值1.51mm，上限值2.8mm。

The distribution taw of K_ values as random variables is examined separately fortwo materials of 43 specimens of aluminum alloy Lc 4 and 30 specimens of alloy steel 30CrMnSiNi2A.

利用统计理论估计出取得在90%的置信度下与真值误差小于5%的K_平均值所需试样数约为4—6。指出在每组K_试验中用最少试样取得满足上述要求的K_平均值的具体方法。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
