These results show that the dual fluorescence of 4-AHBO (5-AHBO) is produced by its different tautomers, hut not by the same isomer: the long wavelength emission is from the keto tautomer, and the short wavelength band is produced by four kinds of enol isomers.
结果表明,4-AHBO(5-AHBO)的双荧光不是由同一种异构体发射的,而是来源于不同异构体的发射:长波区的荧光由酮式构型发射,短波区的发射则可能由四种醇式异构体共同产生。

The main aberrations of the euchromosomes was chromosome gain, including trisome, tetrasome, and polysome. The gain rates of the four euchromo-some were 84.9%, 77.5%, 63.7% and 83.2%, and the frequencies of polysome for each euchromosome were 24.6%, 34.9%, 23.4% and 31.7%, respectively. Loss of chromosome Y was observed in 61.2% of male patients. The combination of the four chromosome probes 3, 8, 10 and 20 detected 74.5% of ESCC and the combination of 3, 8, 20 and Y detected 85.0%.

Our results suggested that the channel contains two of each subunit and the stoichiometry is apt to 2:2 if hetermeric ASIC channel is a tetramer,while the assembly of ASICs is random,the stoichiometry is not fixed(2:1 and 1:2 coexist)if hetermeric ASIC channel is a trimer.This study provided interesting new data supporting the occurrence of the homomeric and heteromeric assembly of ASICs.
另外,我们还对ASIC异聚体的分子比情况进行了初步的探讨,结果发现如果所形成的ASICs异聚体通道是四聚体,那么每种亚单位有两个,分子比倾向于2∶2;如果是三聚体,则提示ASICs的装配是随意的,分子比是不固定的,2∶1和1∶2这两种情况都存在。

In the early 1980s, many researchers revealed the structure of cytoskeleton mainly on kinetosome in the cortex by the employment of protargol staining and ultrastructure method, and thus the configuration, development and mechanism of cortical ciliatures were discussed, which was the major tide in the studies of cell biology of protozoa.

This chapter starts with the determination of primary sense of under. Then it focuses on how its spatial senses are extended from the central image schema to its transformations by metonymy. Next, this part also focuses on how its metaphorical senses are extended in terms of the central image schema and transformations by metaphor. In these analyses, this thesis summarizes four kinds of relations: the relation of UP-DOWN, the relation of HIGH-LOW, COVERING relation or the relation of IN-OUT and the relation of SOURCE-PATH-GOAL. Lots of metaphorical senses of under are derived from these basic spatial relations. In this thesis, the relations between the senses derived from central image schema and those derived from its transformations are explored at length. The relations between the spatial senses derived from central image schema and transformations and the metaphorical senses derived from them are also explored at length. The above analyses demonstrate that the sense extension of the spatial preposition is motivated by image schema, which also provides the root for metonymic and metaphorical extension. The semantic network of under is diagramed finally.
论文首先确定了under的首要意义;然后集中探讨了它的空间意义如何从中心意象图式,通过转喻形成许多变体,从而得以延伸;接着分析了它的隐喻意义如何从中心意象图式及其变体通过隐喻而得以延伸,在此分析中,本论文总结了四种关系:上—下关系﹑高—低关系﹑覆盖关系或里—外关系和起点—路径—目标关系,under的很多隐喻意义源于这些基本的空间关系;本论文还对源于中心意象图式的空间意义与源于其变体的空间意义的关系进行了详细的剖析;对源于中心意象图式与其变体的空间意义及其延伸的隐喻意义之间的关系,也同样进行了详细的剖析;通过分析论证了,意象图式是空间介词义项扩展的源泉,同时也为转喻和隐喻提供了基础;最后得出under的语义网络。
