The thickness of strata in the hanging wall of the growth fault is obviously larger than that in the footwall,and a deposition center was evolved in the Taibei sag where the hanging wall of the fault is located. In late Jurassic the collision between Lhasa block and Eurasia continent resulted in the transformation of the Turpan-Hami basin from an extensional structure into a compressional structure, and consequently in the tectonic inversion of the central structure belt of the Turpan-Hami basin from the extensional normal fault in the earlier stage to the compressive thrust fault in the later stage. The Tertiary collision between the Indian plate and the Eurasian plate occurred around 55Ma, and this Himalayan orogenic event has played a profound role in shaping the Tianshan area, only the effect of the collision to this area was delayed since it culminated here approximately in late Oligocene-early Miocene. The central structure belt was strongly deformed and thrusted above the ground as a result of this tectonic event.展开更多

Predator growth-rate is treated as bifurcation parameter.

The author considered that elements such as teacher＇s understandings of classroom structures, the differences in classroom norms and creation of positive climate could contribute to the overall EFL classroom effectiveness. By referencing contemporary EFL teaching theories, the author attempted to touch on the implications to the contemporary Chinese EFL education. It has suggested that teachers should gain thorough understanding of those elements in their daily practice.展开更多

The as-prepared samples were characterized by X-ray diffraction, transmission electron microscopy, scanning elec- tron microscopy, a constant current charge-discharge test, cyclic voltammetry, and electrochemical impedance spectroscopy. The effects of lithium iron phosphate coating were also discussed. Because of its special core-shell structure, the as-prepared LiMn0.TFe0.3PO4-LiFeP04-C exhibits excellent electro- chemical performance. The discharge capacity reached 136.6 mAh/g and the specific discharge energy reached 506.9 Wh/kg at a rate of 0.1 C.展开更多
