基于二维元胞自动机的温度场模型的分析

铣刀片在切削过程中受到周期性的热冲击，切削热产生恶劣的温度场对刀片造成破损，温度场在铣刀片切削过程中呈现出非常复杂的变化，研究切削热和切削温度的产生和变化规律是揭示刀具破损磨损产生机理的重要手段。利用有限差分法结合切削温度试验和利用元胞自动机理论对铣刀片温度场进行研究，可以建立二维波形刃铣刀片温度场算法系统，得出切削中各点的温度场，为刀片槽型重构奠定基础。     

Chaotic Genetic Algorithm-Based Forest Harvest Adjustment

Forest harvesting adjustment is a decision-making, large and complex system. In this paper, we analysis the shortcomings of the traditional harvest adjustment problems, and establish the model of multi-target harvest adjustment. As intelligent optimization,chaotic genetic algorithm has the parallel mechanism and the inherent global optimization characteristics which are suitable for multi-objective planning the settlement of the issue, Specially in complex occasions where there are many objective functions and optimize variables. In order to solve the problem of forest harvesting adjustment, this paper introduces a genetic algorithm to the Forest Farm of Qiujia Liancheng Longyan for forest harvesting adjustment firstly. And the experimental result shows that the method is feasible and effective, and it can provide satisfactory solution for policy makers.     

新个税法对调节收入分配的影响

个人所得税是现代政府组织财政收入、调节收入分配的重要手段。我国1980年开始征收个人所得税,2011年9月1日起实施新个税法。新个税法大幅度减轻了中低收入纳税群体的负担,顺应了时势和民意。但是,由于现行个税制度自身的缺陷以及个税在税收结构中的比重偏低,其调节收入分配差距的功能仍十分弱小。因此,必须加快个税制度改革,完善个税调节功能,使其真正发挥在构建公平收入分配关系中的重要作用。     

浅论术语学是知识技术的前提

20世纪70—80年代，随着信息技术的发展，人们越来越认识到术语学在知识产生、知识获取、知识代表和知识传递过程中所起的基础性作用。欧洲的术语学家从人们对信息流的研究和对知识秩序的重视上得到启发，设计了普通术语学的概念动力学模型，揭示出术语学和知识技术相互依赖、彼此依存的内在联系，并由此得出术语学和知识技术一体化的模型。文章着重对这一理论发展过程进行论述，以期为中国术语学理论提供一个新的研究视角。

Sedimentation processes and sedimentary characteristics of tidal bores along the north bank of the Qiantang Estuary

A tidal bore is a unique Earth surface process, characterized by its highly destructive energy, predictable periodicities and magni-tudes, and the production of characteristic sedimentary features. Tidal bores and associated rapid flood flows are highly turbulent flows of the upper-flow regime with a velocity over several meters per second. Reynolds (Re) and Froude (Fr) numbers, respectively, are larger than 104 and 1.0, making them significantly different from regular tidal flows but analogous to turbidity currents. Until now, understanding of tidal-bore depositional processes and products has been limited because of the difficulty and hazards involved with gauging tidal bores directly. The Qiantang bore is known as the largest breaking bore in the world. Field surveys were carried out in May 2010, along the north bank of the Qiantang Estuary to observe the occurrence of peak bores, including regular observations of current, water level and turbidity at the main channel. Several short cores were sampled on the intertidal flats to study the characteristic sedimentary features of tidal bores. Hydrodynamic and sedimentological studies show that the processes of sediment resuspension, transport and deposition are controlled primarily by the tidal bores, and the subsequent abruptly accelerated and decelerated flood flows, which only account for one tenth of each semidiurnal tidal cycle in the estuary. Tidal-bore deposits are generally poorly sorted because of rapid sedimentation after highly mixed suspension by intense turbulence. This behavior is characteristic of the absence of tractive-current depositional components in a C-M diagram. It also goes along with well-developed massive bedding, graded bedding, basal erosion structures, convolute bedding and dewatering structures. Together, these sedimentary features can constitute fingerprinting of turbidites, widely distributed in the deep-water environment. However, a tidal bore is triggered by intensely deformed tidal waves propagating into a shallow-water environment, which returns to regular tidal flows rapidly after the passage of the bore head. The tidal-bore deposits are usually bounded by the intertidal-flat deposits with typical tidal beddings at the top and on both flanks. The difference between tidal-bore deposits (TBD) and tidal sandy/muddy deposits (TSD/TMD) is evident not only in sedimentary structures, but also in the grain-size composition. They can be clearly distinguished in grain-size bivariate plots, typically the plot of mean grain size vs. standard deviation (or sorting). Some trend variations generally exist in mean grain size with TBD>TSD>TMD, sorting with TMD>TBD>TSD (larger value indicating poorer sorting), and both skewness and kurtosis with TSD>TBD>TMD. These findings will undoubtedly shed new light on our understanding of tidal-bore sedimentology, ancient tidal-bore sedimentary facies and environments, and related oil-and-gas field prospecting.     

Optimal design of label-free silicon“ lab on a chip” biosensors

This paper reported the optimal design of label-free silicon on insulator(SOI) "lab on a chip"biosensors.These devices are designed on the basis of the evanescent field detection principles and interferometer technologies.The well-established silicon device process technology can be applied to fabricate and test these biosensor devices.In addition,these devices can be monolithically integrated with CMOS electronics and microfuidics.For these biosensor devices,multi-mode interferometer(MMI) was employed to combine many stand-alone biosensors to form chip-level biosensor arrays,which enable realtime and label-free monitoring and parallel detection of various analytes in multiple test samples.This sensing and detection technology features the highest detection sensitivity,which can detect analytes at extremely low concentrations instantaneously.This research can lead to innovative commercial development of the new generation of high sensitivity biosensors for a wide range of applications in many fields,such as environmental monitoring,food security control,medical and biological applications.
