分数的

In recent years, systems which based on fractional differential and integral fractional, have been researched extensively, involving fractional circuit, fractional digital signal processing, fractional dynamics control systems and fractional-Chaos and super-chaos, Chaos Control and fractional chaos synchronization, and security communications. And a lot of theoretical and practical results are obtained.

Using DC and AC poling methods, three groups of polarized PZT/P 70/30composites have been prepared by poling only the ceramic phase(1), both ceramic and polymerphases in the same(2) and opposite(3) directions. Piezoelectric coefficients of group 1 compositesincrease as the PZT content increasing, while for group 2 composites, the piezoelectric coefficientschange the sign with increasing PZT content because piezoelectricity of copolymer is increasinglycompensated by that of PZT, and PZT content for zero-〓 isn't that for zero-〓. The experimentdata of both group 1 and 2 composites agree well with EMT-Shin model.

对复合材料的压电性能：只极化PZT粒子相的复合材料的压电系数随陶瓷分数的增大而增大，PZT粒子相与共聚物基体同向极化的复合材料的压电系数由于两相效应的部分抵消，随陶瓷含量的增大，发生符号的改变，且〓和〓零点不重合，它们与EMT-Shin模型都符合较好；而两相反向极化的复合材料的压电系数由于AC反向极化会导致陶瓷相极化程度的下降，导致实验值和理论预期偏差较大，尤其在PZT粒子高含量区。

He strutted around the court with his now customary swagger, torpedoing balls with complete disregard to the score and occasion that underlined his high expectations.97年,safin的第一次kremlin杯比赛中,在输了第三个抢七之后败给了老手 Kenneth Carlsen.

他是速度与天然的power的结合体，这种power那样的浑然天成，而不是粗暴的蛮力。safin那把红色的Head网球拍在他手上显得那么渺小，就如同摆动一根树枝。他在球场上用他那特有的傲慢展示着自我，无视分数与场合毁坏着球，这也是对于他高期待的不屑。

一次在Lee大学进行的研究发现，那些一直参加由税收支持的公立学校的青少年学生的第一学期成绩比那些曾接受过家长在家中进行的教育的学生低一些，尽管这种分数的差异在第二学期就消失了。

22 Vs TD: 21 70 ? 5 09 p = 0 11 and ball skills subtest of M-ABC (Z =-2 256 p = 021) The correlations of the scores of two motor tests and their subtests were fair to good (r =- 264 ~- 645 ) Conclusion: Children with FAD present similar overall motor performance except of lower scores of fine motor precision and ball skills The correlations of scores of two motor tests are only fair to good Clinical Relevance: Clinical therapists should be cautious that children with FAD may have a comorbid motor problem especially the fine motor precision and ball skills Only fair to good correlations of scores of the two most commonly used clinical tests indicates that it should be cautious when choosing a motor test for certain purpose

能性构音障碍儿童： 59 60 ± 9 16；正常发展儿童： 64 93 ± 8 77 p = 026、精细动作精准分测验(？能性构音障碍儿童： 18 53 ± 4 22；正常发展儿童： 21 70 ± 5 09 p = 0 11)与Movement-ABC的球类技巧分测验(Z =-2 256 p = 021)的表现显著较正常发展儿童差。而两动作测验与其分测验之间分数的相关性仅有中等至良好的相关（r =- 264 ~- 645）。结论：？能性构音障碍儿童在整体动作表现与正常发展儿童类似，但在动作中之精准控制能力较一般儿童差。BOT-2与Movement-ABC两种动作测验与其分测验之间仅有中等到良好的相关，显示两动作测验在本质上仍有不同，并不能互相取代，因此在使用时应考虑受试者的特质与目的等因素，以期使用最合适之评估工具。
