Based on the construction of a new distance-preserving Gray map from(（F;+ uF;）;, Gray distance) to(the corresponding Gray images in F;, Hamming distance) and the calculation of Gray distances of（u-1）-constacyclic codes over F;+ uF;, a bound for the Hamming distances of a class of negacyclic codes with length p N over F;is obtained, which is more tighter than Singleton bound. Further more, the exact Hamming distances of some p-ary negacyclic codes are determined from this bound, some of which cannot be got from Dinh’s work published on Finite Fields and Their Applications in 2008.

职前教师学科教学知识的认知包括学科知识认知与教学实践两个层面。研究基于9位职前教师的27次反思报告,运用质性研究方法,通过分析职前教师对学科知识的诠释、重组、呈现,探究职前教师学科知识认知与教学实践之间的关系,并阐释职前教师学科教学知识的认知困境与原因。研究发现,如果职前教师未能意识到学科知识的独立性和专业性,则很难恰当地将学科知识融入教学实践,以致教学实践中存在学科知识欠缺的现象。故教师培养者应补充相关的学科知识,以帮助职前教师形成合理、整体、全面的学科教学知识;职前教师应深化、重组学科知识认知,调整审视教学内容的视角并在教学实践中恰当地呈现学科知识。

A chronological study of seamount rocks in the South China Sea basin provides a great opportunity to understand the expansion and evolution history of the sea basin. In this paper, we analyzed the ^40Ar/^39Ar age of trachytic samples collected from the Shuangfeng seamounts in the northwestern sub-basin of the South China Sea. The two samples yielded plateau ages of 23.80 ± 0.18 and 23.29 ± 0.22 Ma, respectively, which indicate magmatic activity in late Oligocene which helpful constraints the expansion time of the northwest sub-basin. Previous studies suggested that the northwestern sub-basin and southwestern sub-basin have experienced a relatively consistent expansion in the NW-SE direction followed by a late expansion of the eastern sub-basin. We concluded that the expansion of the northwestern sub-basin began prior to ca. 24 Ma, which also implicated magmatic events of a late or stop expansion of the northwestern sub-basin combined with our results of^40Ar/^39Ar age data and previous geophysical data.

The evolvement of complex networks is based on self-contained ultra-large system, but in fact all possible described networks are almost not completeness sub-networks. We study the more complete information description of complex system through introducing autonomous system and external degree, and investigate the statistical properties of external edges. The external nodes, external edges, and external degree provide natural and powerful extension for the traditional network concept of complex physical system, capable of providing more comprehensive information about the connectivity properties of the graph topology. Complex network with external degree provides scalable scale analysis for complex system with as less cost as possible. Experiments reveal that external degree also follows power-law distribution.

To explore the effect of temperature on the phase transformation of HCP→FCC during compression, the uniaxial compression process of AZ31 magnesium alloy was simulated by the molecular dynamics method, and the changes of crystal structure and dislocation evolution were observed. The effects of temperature on mechanical properties, crystal structure, and dislocation evolution of magnesium alloy during compression were analyzed. It is concluded that some of the Shockley partial dislocation is related to FCC stacking faults. with the help of TEM characterization, the correctness of the correlation between some of the dislocations and FCC stacking faults is verified. Through the combination of simulation and experiment, this paper provides an idea for the in-depth study of the solid-phase transformation of magnesium alloys and provides reference and guidance for the design of magnesium alloys with good plasticity and formability at room temperature.
