The source terms of a tensile dislocation are presented in terms of the wave number and circular *** for displacements on the surface of a half-space due to an arbitrary oriented dislocation are also obtained by using the generalized ray *** result shows that the far-field waveforms contributed by tensile source are different from other sources. Considering that not all of the large earthquakes can be explained with the shear dislocation model, these expressions may be efficient in analyzing some earthquakes.

研究包括两部分。在第一部分,通过对南10个发音人发音的14.条句子中的4.词时长方面的声学特征的分析发现:(1)当句子重音强调词时,时长的增加主要集中在这个词的重读音节上;(2.当句子重音强调词的某个音节时,时长的延长主要集中在这个音节上。在第二部分,通过使用上述语句的知觉实验发现,句子重音强调词的语句和句子重音强调这个词的重读音节的语句相对于它们的语境是可以相互替换的,这种相互可替换性起因于这两种语句声学表现方面的相似性。

Activity of the truncated promoter of pollen-specific G9 gene of cotton and the transgenic recessive nuclei-sterile tobacco

引用

Progress in Natural Science:Materials International 2002年第3期 46-49页

作者： MA Hong, WANG Huanyu, LIU Yule, YANG Huaiyi and TIAN Bo(institute of Microbiology, chinese academy of sciences, {2. 100080, china) Present address: Dalian University of Technology Dalian 116024 China institute of Microbiology Chinese Academy of Sciences Beijing 100080 China

A 557 bp fragment from the translation initiation site of the G9 gene expressed in maturing pollens of cotton was isolated from genomic DNA of upland cotton (Gossypium hirsutum L.) cv. "Zhongkang 17", and two expression vectors for plant transformation were constructed via fusing this fragment with β-glucuronidase gene ( Gus) and cytotoxin gene Barnase . The promoter activity of this fragment was demonstrated via transient expression of Gus gene in cotton and by the integrated expression of Barnase gene in tobacco. This promoter can initiate the expression of exogenous gene specifically and efficiently in plant pollen. The transgenic tobacco plant containing G9-Barnase fusion gene showed the characteristics of recessive nuclei-sterility.
