Heat flows derived from garnet, chromite/chromium-spinel and pyroxene of xenoliths, xenocrysts in Mengyin and Fuxian kimberlites are higher than 40mW/m〓 calculated from the pyroxene inclusions in diamonds, and the range of pressure is 20~40kb (equivalent to 65~130km). Metasomatism (as indicated by yimengite and lindsleyite in Mengyin) is very strong in this depth range. Lherzolite, wehrlite, and diamond-free high-Ca harzburigite around the world are derived from this depth also. The observation suggests that the low-Ca harzburigitic environment for diamond stability had been changed significantly when the kimberlitic magmas erupted. This resulted from fluid interaction with harzburigite. The geotherm of the Cenozoic lithospheric mantle beneath Eastern-North China platform is higher than oceanic one. The temperature from the interior of the Tan-Lu faults is higher than that from apart off the fault.

After analysizing the results of SSRFEM and centrifugal model test, someconclusions are drawn that, the depth of slip surface implies that the Bishopssimplied method cannot indicate the true failure mechanism for the slopes reinforcedwith piles. The rate of safety factors decreases with the pile spacing decreasing, andthe salty factor of the slopes is the largest when the reinforced piles are installed in themiddle of the slopes, regardless of pile head confining conditions, and the deflection,maximum bending moment and shear force in the reinforced piles in the criticalcollapse are the biggest meantime. The fixed and hinged head condition of the pilesresults in smaller bending moment in the piles than that in unrotated and free headcondition, therefore the restrained pile head condition is recommended in the design.
3不同特性与工况下抗滑桩与土体相互作用的数值分析与离心模型试验研究表明:采用简化Bishop法计算得到的滑动面不能反映抗滑桩加固边坡的破坏机理,抗滑桩设置在边坡中部和减小桩间距有利于提高边坡稳定安全系数,而此时抗滑桩在边坡临界破坏时的挠度、最大弯矩和最大剪力相对较大;桩头固定、铰接与桩头自由、平移相比,所加固边坡的整体水平位移及边坡临界破坏时抗滑桩的最大弯矩相对较小,而稳定安全系数则较大,因此在进行抗滑桩设计时应尽量选择桩头固定与铰接的型式,或对桩头进行锚固以改善抗滑桩的受力特性,提高边坡的稳定安全性状。

The experimental results show the validness of the mechanism analyses.2. According to the generation mechanism of the leak acoustic signal, the characteristics of the leak acoustic signal are investigated. The auto correlation technology is adopted to descript the leak signal characteristics due to the ability to analyze the coherence of time series. A new procedure to identify the leak acoustic signal from the disturbed noises is proposed based on the conjunction of correlation and approximate entropy algorithm.3. The principle and application in leak location of the correlation and the adaptive filter techniques are introduced. The problems of the traditional leak location methods are analyzed.4. In order to establish the leak detection signal model, the leak acoustic propagation characteristics are investigated experimentally.

We proposed that the non-adiabatic passage at zero-crossings of quadrupole splitting would not lead to the great loss of the spin locking signals, and the second-order quadrupolar interaction had significant effects on triple-quantum coherences, which was responsible for the fast decay of the signals; the both experiments and numerical simulations supported this point of view.

After impacting, the normal incident C〓 was found to move laterally on the surface due to the anisotropic interaction between the dimerized surface and the cage. Finally, it resided on the top of a dimmer or in the trough, which are the energy favored adsorption sites.

Conjugated polymers which are different from traditional semiconductor, have some unique properties. Most of them are quasi-one-dimensional systems with strong electron-phonon interaction. Their carriers are composite particles, which are different from simply electron and hole, characterized with the surrounding distortion of lattice configuration (polaron with spin 1/ 2 , bipolaron with spin 0 etc.). The transport of the carriers and the process that oppositely charged polarons combine to from exciton are believed to be of fundamental importance for electroluminescence properties.
