The Zeeman shift of the 5 s5 p ^3 P0-5 s^2 ^1 S0 forbidden transition is measured with the π-polarized and σ^±-polarized interrogations at different magnetic field strengths. Moreover, in the g-factor measurement with the σ^±-transition spectra, it is unnecessary to calibrate the external magnetic field. By this means, the ground state 5 s^2 ^1 S0 g-factor for the ^87Sr atom is-1.306(52) ×10^-4, which is the first experimental determination to the best of our knowledge, and the result matches very well with the theoretical estimation. The differential g-factorδg between the 5 s5 p^3 P0 state and the 5 s^2 ^1 S0 state of the ^87Sr atoms is measured in the experiment as well,which are-7.67(36) ×10^-5 with π-transition spectra and-7.72(43) X 10^-5 with σ^±-transition spectra, in good agreement with the previous report [Phys. Rev. A 76(2007) 022510]. This work can also be used for determining the differential g-factor of the clock states for the optical clocks based on other atoms.展开更多

Because of the high elevation, cold climate and it caused difficulties in regional economic planning and land resources management. Since 1985, the land use investigation in Tibet has been carried out, in which the basic data and thematic maps must be obtained and completed at county and township levels, in order to meet the needs of local administrations. In the investigation, remote sensing technology was comprehensively adopted. At present, the investigation in county level had been completed and the compilation is going to be carried out. Due to paying a great attention to studying on a series of key technical problems, the systematic methods of using remote sensing technology in the plateau land use investigation were formed and successfully put into application.展开更多

As a traditional ritual of holding marriage for the dead, ghost marriage embodies premodern views of time and space wherein the living and the dead are perceived as coexisting in parallel spaces, and the boundary of life and death is seen as transcendable through the extension of kinship. In this way, the dead are kept within the family, maintaining the warmth of familial relationships that transcend being and non-being. Modern authors, promoting a linear view of time, have taken up ghost marriage as an anchoring point of nostalgia for an unrecoverable ethics-based society. For instance, Yan Lianke's 阎连科 1994 novella Searching for the Land (寻找土地) announces the utter corruption--and therefore the death--of ethics-based society, suggesting that the only alternative is to confront the future as a road to hope rather than indulge in an illusion of the past. Through an analysis of Yan's novella, this essay discusses how the theme of ghost marriage fits into the broader literary context of the early 1990s while also anticipating some of the distinctive elements ofYan Lianke's subsequent novels.展开更多
