The sloping plate can provide sufficiently the under-cooling for nucleation and lay a foundation for heterogeneous nucleation to form lots of nuclei of crystal internally and on the sloping plate surface, thus causing the melt to nucleates eruptively. Under the action of both metal flow and vibration, the nuclei formed on the sloping plate surface can move freely and disperse into the melt, and they are able to maintain the direct growth in spherical shape in the homogeneous composition and temperature fields.

In the chiral SU(3) quark model, we use the coupling between quarks and nonet scalar meson fields and nonet pseudo-scalar meson fields to describe the medium and long range interactions, and use one gluon exchange to describe the short range interaction. In the extended chiral SU(3) quark model, besides the nonet pseudo-scalar meson fields and the nonet scalar meson fields, the coupling between vector meson fields and quarks is also considered, the short range interaction can be dominately described by vector meson exchange. We investigate the nucleon-hyperon interaction in the extended chiral SU(3) quark model and study the S-wave phase shifts of N-Λ and N-Σ systems. Comparing to the results in chiral SU(3) quark model, we find that the short-range interaction could be described either by the one-gluon exchange or vector meson exchange.
在手征SU(3)夸克模型中,用夸克与标量介子九重态和赝标介子九重态场的耦合来描述中长程相互作用,单胶子交换来描述短程相互作用,推广的手征SU(3)夸克模型是在原来手征SU(3)夸克模型的基础上进一步引入了夸克和矢量介子九重态场的耦合,主要由矢量介子交换来描述短程相互作用,在推广手征SU(3)夸克模型下研究了核子-超子相互作用过程,计算了N-Λ和N-Σ相互作用的S波散射相移,通过和手征SU(3)夸克模型的结果比较,发现N-Λ和N-Σ系统的短程相互作用既可以由单胶子交换来描述,也可以由矢量介子交换来描述。

For the first time, we investigated the possibility of using non-minimal coupled scalar field (include Real and Complex scalar fields) as the candidate of dark energy---Quintessence or Phantom. A cosmological model droved by real scalar field with accelerating and decelerating, forever cycling and expanding was constructed. Classical and quantum wormholes with Tachyon fields were discussed in detail. The entropy of sphere symmetric black holes due to arbitrary spin fields was studied, and the proportional relations between entropy and fields degeneracy was derived. For the first time, we investigated the neutrino quasinormal modes of stationary black holes in the background of de Sitter space-time, and the quasinormal modes of Schwarzschild black holes with arbitrary spin fields. We also studied the quantum teleportation in the background of curved space-time for the first time.

The study indicates that the content of soil carbon is on the low side because human behavior has a negative effect on sloping cropland. However, the content of every group soil carbon increased drastically by planting Robinia . With the increasing of the time of conservation, the relationship is very remarkable. After 50 years of restoration, the content of TOC, LOC, NLOC and AI in the study plot increased by 271%,174%, 467%, and 271%, respectively, compared with sloping cropland. The increasing speed of NLOC was faster than LOC. It is assumed that the increased carbon by restoration is stored in an inactive form to produce active matter which is necessary for biont. And the soil carbon must keep active to fulfill the balance of carbon dynamic transformation. At initial stages, soil carbon management index increased remarkably.
营造刺槐林可以显著增加土壤碳库各组分含量,并随恢复年限呈显著线性关系,50a时TOC、LOC、NLOC和碳库指数分别较坡耕地增加271%、174%、467%和271%,其中NLOC增加速率略高于LOC,表明植被恢复增加的土壤碳素绝大多数以非活性形态贮存起来,而为了满足生物生长所必须的活性物质来源,土壤碳库必须维持一定的活度状态来满足碳素的动态转化平衡,碳库管理指数在营造刺槐林初期显著降低,随后先增加后降低,与刺槐林生长特性密切相关;但与天然林相比差距仍然较大,恢复50a时TOC、LOC和NLOC仅为侧柏林的49%、34%和61%。

Results showed that the overland flow pattern has close relationship with the grass cover and water inflow rate, it changed from the laminar and tranquil flow to the transition flow and tranquil flow for the grass-covered sloping segment with increasing water inflow rate, but it was almost transition flow and tranquil or rapid flow for the sloping segment without grass cover.
