Comparing the unsteady flow fields obtained by CFD with the measurement results with SPIV, it can be found that the CFD results can capture the main characteristics of the flow fields observed in the experiment results, however, the precision of the CFD needs to be further improved, and to predict the detail flow structures, such as the tip leakage vortex in the compressor rotor, by CFD still has some difficulties, thus, some work should be done to improve the turbulence model for more accuracy prediction of the flow fields by CFD for the complex flow in turbomachinery.

定常计算结果和非定常计算结果都不能很好地反映出转子叶尖泄漏流，转子尾迹和泄漏流在静子通道中的演化，及其与静子的相互作用等复杂流动情况。开展叶轮机适用的湍流模型研究，对于提高叶轮机内部复杂流动数值模拟的准确性具有非常重要的价值。

SPIV was applied to a large-scale low-speed compressor facility with the configuration of the two CCD cameras placed on either side of the light sheet to make the measurement of the complex flow in hub-to-tip cross sections possible and to avoid the disturbance from the light sheet probe as used in the periscope-type configuration, which can also be easily used in multistage and high-speed turbomachinery.

本文将数字式SPIV技术应用到低速大尺寸压气机实验台上，解决了压气机内部非定常复杂流动瞬态场的技术难题，所发展的SPIV测量技术同样适用于多级叶轮机械；并在设计状态和近失速状态下，对转子槽道内叶尖区域及转静干扰条件下静子槽道内叶尖区域多个截面内的三维瞬态速度场进行了成功测量。

应用HSP70单克隆抗体免疫组化染色检测大鼠再灌注6、12、18、24、48及72h脑皮质HSP70表达的变化；并与病理组织学改变进行对照研究。2.20只雄性新西兰大白兔随机分成对照组（n=10）及葛根素组（n=10），所有动物均阻闭腹主动脉肾下段20min，建立兔脊髓腰尾段缺血模型。

In the BC〓F〓 and BC〓F〓 generation of Yannong15×Thinopyron intermedium hybrid, 4 octoploids which had chromosome number of 2n=56 and could form 28 bivalent at PMC MI, 14 disomic addition lines which had chromosome number of 2n=44 and could form 22 bivalent at PMC MI; three monosomic addition lines which had chromosome number 2n=43 and had the chromosome configuration of 21Ⅱ+1Ⅰ at PMC MI, 1 substitution line which had chromosome number 2n=42 and could form 21 bivalent at PMC MI were selected by observation of mitosis in root tip cell and meiosis in pollen mother cell.

在烟农15与中间偃麦草杂交的BC〓F〓和BC〓F〓代中，通过根尖有丝分裂和花粉母细胞减数分裂中期Ⅰ观察选出4个2n=56，PMC MI染色体构型为28Ⅱ的八倍体小偃麦；14个2n=44，PMC MI染色体构型为22Ⅱ的双体异附加系；3个2n=43，PMC MI染色体构型为21Ⅱ+1Ⅰ的单体异附加系；1个2n=42，PMC MI染色体构型为21Ⅱ的异代换系。

The experimental results show:(1) The water in South Fei River has been comtaminated, especially in industrial and residential part.(2)Vicia faba(QI_1) is sensitive to mutagen, and liner relation between the freguency of micronuclear cell in the root tip cells of Vicia faba(QI_1)and concentration ...

结果表明，南淝河水体已被污染，尤其以工业区和居民生活区污染严重；启豆Ⅰ号对诱变物反应敏感，水环境中污染物浓度与微核千分率呈线性相关，因此启豆Ⅰ号作为微核监测技术的实验材料是可靠的。

The extensive variation in chromosome number in root tip cells of three Chinese cabbage-cabbage monosomic alien addition lines with 21 chromosomes, 6-2-4, c-2-4 and d6, was obsevered after vegetative propagation multi-generations. The chromosome number varied from 17 to more than 50. The 25S rDNA signals were very complex in the three different clones.

染色体数目为21条的3个大白菜-结球甘蓝单体异附加系6-2-4、c-2-4和d6，在无性繁殖多代后根尖细胞均出现了广泛的染色体数目变异的现象，变异范围从17条到50多条不等，25S rDNA在这些无性系的FISH杂交信号较为复杂。

In this case is not the device, this time there is a concept, it was said that in the late Palaeolithic period have been such a jade appeared, in Liaoning Xiaogushan sites, we also found the same shape and stone, jade This tip-like device, but at that time and there is no fundamental difference between the same stone.

这里指的并不是器，这个时候有一个概念，有人说在旧石器时代晚期，已经有这种玉器出现了，在辽宁的小孤山遗址里，我们也发现了和石一样形状的、玉的这种尖状器，但是那个时候和石器一样没有本质的区别。

The strength of the torrent current pull and drag Li3 Lang2 Ye2 is toward the surface of eminence, the small dragon that is before the body make great effort inside out in the bumpy air body, see toward his look in the eyes, still is that kind of is stubborn of gentleness ……he the direction of unconscious facing small dragon stretch out a hand go to-blue of Yan fire drive blunt spread into stars to order, Shan write the fluorescence be upper-class to lead from the finger tip, be like the broken bits of Cang jade and point to sew in cold and slipperily feel
