Results In the 14 cases, 13 achieved bone union and one nonunion. The mean time of union was 12 weeks. The wrist mean motion range was about 90% of the healthy lateral wrist and mean gripping strength was about 95%. Twelve patients suffered from no pain, one patient from slight pain, and one patient with nonunion from medial pain. According to Cooney's clinical evaluation system, the outcome was fine in 10, good in three and bad in one patient.

The observational and calculated results are well matched. The calculated mean diameter, mean square-root diameter, mean cube -root diameter and liquid water content are all well matched with the observational results; In the paper two examples have been analyzed by using the seeding region data and the possible affecting region data in leeward region. It is found that F-100, 2dc, and 2dp's particle concentrations increase in leeward region, but rising extent is different, which is likely to be due to difference of seeding effect time.

拟合值和观测值吻合的较好，计算出的平均直径、均方根直径、均立方根直径和粒子浓度与观测值也比较吻合；本文对两组个例的催化影响区域及可能采集到相应值的下风方区域进行了分析，催化下风向影响区的F-100、2DC、2DP的粒子浓度比背景值都有所增加，但是增加的幅度不同，应该是催化响应时间的原因。

Paired Samples T test revealed that both the LT and VL decreased (P.01), the AD increased (P.01) after cycloplegia regardless of their refractive state. The AL increased for hyperopic eyes (P.05) and decreased for myopic eyes (P.01) after cycloplegia. For hyperopic eyes, the major keratometer K1 increased (P.05) while for myopic eyes, the major keratometer K1(P.05) and minor keratometer K2 (P.01) decreased after cycloplegia. The mean corneal power of zones 5 mm (MD5) and 7 mm (MD7) decreased with myopic eyes decreased dramatically (P.01). The mean refractive power of the lower half vertical meridian is greater than that of upper half; and the mean refractive power of the lateral half of the horizontal is greater than that of the medial half.

结果：不论远视眼、正视眼还是近视眼在睫状肌麻痹后前房加深（P.01），晶状体变薄（P.01），玻璃体腔径缩短（P.01）；但远视眼睫状肌麻痹后眼轴增长（P.05），近视眼眼轴缩短（P.01）；远视眼睫状肌麻痹后角膜曲率K1增加（P.05），近视眼睫状肌麻痹后除K1降低外（P.05），K2以及以角膜中心点为中心，直径为5mm、7mm的环平均角膜屈光度（MD5、MD7）均降低（P.01）；此外，垂直径线上方的平均角膜屈光度小于下方的平均角膜屈光度而水平径线鼻侧的平均角膜屈光度小于颞侧的平均角膜屈光度（P.01）。

First, the contributing degree of indices and their mean can be solved by means of the theory of contribution degree; secondly, the deviation of weights from the mean of these weights is determined according to the deviation of contributing degree of indices from the mean of contributing degree. Based on this, the formula of solving weights can be derived.

用贡献度理论求得各指标的贡献度，并求其均值；以各指标的贡献度与均值的差为参考，确定相应指标的权与权均值的差，并以此为依据建立权值的求解公式，求得相应指标的权。

In this beamline, with the neutron depolarization technique, provides information of the mean domain size, the mean square direction cosine of the magnetic induction in the domains, and the mean magnetization of a magnetic sample.

三维去极化中子仪主要为观察极化中子通过磁性材过程，受到内部磁区的扰动使得极化中子向的方向和大小改变，进分析后可以观察出材内部平均磁区大小、平均感应磁场强、磁区平均方向余弦的平方。

Higher value of mean endomorphy and mean mesomorphy showed male students had much fat and more developed skeletal and muscle systems than female students. Compared with other regions, college students in Qingdao area were fatter,and skeletal and muscle systems were poorly developed. The comparison of the mean ectomorphy and the body length/body weight showed that the male was close to the female on the body linearity.
