Comparing the computation results of these four design schemes we get variation of the kinetic energy correction factor near groynes in Panjiatai shoal when water depth is less than the groyne height. The variation characteristics of the kinetic energy correction factor in Panjiatai shoal is different from the experiment results because the effect of groynes in the Panjiatai shoal is simulated by three parameters together.

比较四个方案的计算结果，可以得到潘家台滩绕流流态下丁坝附近动能修正系数的变化情况，与实验进行对比，分析两者产生差异的原因是潘家台滩工程中丁坝对水流的影响由三个参数共同来模拟。

The results showed that ABT can increase the content of geniposidic acid in a long time, the range of variation was more than 9%, but most of the time, it would decrease the contents of chiorogenic acid, total flavonoids and gutta-percha, the range of variation was large too.

结果表明：ABT生根粉处理后，杜仲叶中京尼平武酸的含量在较长时间段内增加，增加幅度超过了9%；绿原酸、总黄酮和杜仲胶的含量减少，减少幅度较大。

We also measured the content of indogenous IAA in different nodes in monoecium and gynoecium, and the variation of indogenous IAA and gibberellic acid at the different developing stages in cucumber after being treated with exogenous GA〓: the variation of ethylene release and the activities of ACC oxidase at the different developing stages after being treated with exogenous IAA and GA〓.

进一步比较了外源GA〓处理后，不同发育阶段雌性系黄瓜品种中的内源生长素和赤霉素含量的变化情况，结果表明：GA〓处理后的雄性化作用与降低黄瓜植株中内源生长素含量以及提高内源赤霉素含量有关，而生长素含量的降低则可能抑制了内源乙烯的释放。

The power variation of the targeted harmonic signal and harmonic suppression ratio were calculated and evaluated. The theoretical caculations and simulated results suggest that power variation can be maintained within 1 dB with dc bias drift less than 5% and the harmonic suppression ratio is stable in the SSB RoF link.

理论计算和仿真结果表明，偏置漂移会使目标信号的功率抖动增大，但当偏置漂移量小于5％时，功率抖动小于1 dB，而谐波抑制比保持稳定；分析了与非理想光电调制器啁啾相关的有限消光比和双臂驱动不平衡度对RoF链路性能的影响，有限消光比会增加目标信号的功率抖动并降低谐波抑制比，而通过优化调制器的双臂驱动不平衡度可以提高单边带调制RoF链路性能。

Available data on helminth genetic variability have shown that most helminth populations exhibit different levels of genetic variation resulting mainly from the pattern of life cycle,geographical distribution and parasite-host interaction,and several hypotheses have been proposed to explain the genetic variation.

应用这些遗传标记的研究表明，大多数寄生蠕虫群体遗传结构有不同水平的变异，这些变异的产生主要与寄生虫的生活史和群体生态、宿主的地理分布和环境等因素有关，并因此提出了有关遗传变异的一些假说。

This study clearly showed that mosaic variation was caused by chlorophyll deficiency mutation of shoot tip histogen layer-Ⅱ;tissue and organs originated from the layer-Ⅱ couldn't synthetize chlorophyll,thus induced albino; the albino variation appeared yellow green mosaic because layer-Ⅱ was displaced by layer-Ⅲ partly.

研究表明，其变异原因是由于茎尖分生组织的L -Ⅱ组织原层发生失绿突变，致使其衍生的组织和器官不能合成叶绿素，从而形成白化现象；又由于L -Ⅱ与L -Ⅲ组织原层层间发生部分代换，致使白化突变呈黄绿镶嵌的花斑。

The differentiation coefficient is 0.07 between three inbreed families respectively. The highest level of genetic homozygosity is in families Ⅱ at 18, but genetic variation is a little difference between inbreeding pig and mice. However, this study revealed the pattern of genetic variation at microsatellite loci in the 3 inbred families of WZSP with one of the most important findings to be the high level of unexpected heterozygosity at some loci, e.g. Sw874 and Sw936 that could be part of the unique genetics of three families. A hypothesis is that certain functional genes linked with such microsatellite loci may be involved in the maintenance of viability of these inbred families of WZSP remains for further investigation.

随近交代数的推进，每个星座上等位基因数越来越少，基因的纯合度越来越高，但WZSP近交系微卫星等位基因的纯合度有一定的限度，与近交鼠有所不同；在近交系3个家系各个世代中有少数几个基因座，如Sw874和Sw936等一直处于高度杂合状态，这可能与WZSP近交家系的种质特异性有关，推测与这些基因座处于同一连锁群的某些功能基因在维持极高近交水平下WZSP的基本生存能力中起着关键作用。3个近交群体间的分化系数在0.07以上，已各自成为独立家系；3个家系的近交程度不完全一致，基因的纯合度亦不同，Ⅱ系最高、14个微卫星座中7个纯合，其次为Ⅰ系和Ⅲ系。
