Reanalysis on the Spectral Characteristics and Materials of Jade Jue Unearthed from Lijiashan Ancient Tomb in Yunnan Province, China

Jade ware Jue is one of the most fashionable ornament in ancient China from the Neolithic Age to the Han Dynasty.In this study,the remnants of jade ware Jue,from Lijiashan ancient tomb group have been tested and analyzed respectively.The samples through a light etch surface showing glass luster and those with a severe etch surface showing earthen luster.With the aid of X-ray fluorescence Spectrometer(X-ray Fluorescence)test and X-ray diffraction(XRD)detection,the results show that tremolite is not the main mineral of the sample.The main components of the tested samples with light erosion are antigorite and talc,although the main components of the samples with severe erosion are calcite containing calcium carbonate barium.Furthermore,the research on jade ware Jue in Yunnan culture has not only contributed to our further understanding of the jade objects from Yunnan culture and the variety of jade material located in the Yunnan Province.It also provides a basis for the trace of the history and culture through the distribution and evolution of burial hierarchy laws.At the same time,the microscopic observation of the tested samples manifested a residual trace of“string”at the perforation,which has played a critical role in restoring the wearing of jade ware Jue from the tombs of the ancient Yunnan State and the handicraft skills at that time.

The Application of Newmark’s Metaphor Theory in Novel Translation--A Case Study of“the Jade King:History of a Chinese Muslim Family”

This paper examines the metaphorical part of“The Jade King:History of a Chinese Muslim Family”,Hoda’s novel,under the guidance of Newmark’s theory of metaphor.Newmark proposes six categories of metaphors,namely Dead Metaphor,ClichéMetaphor,Stock or Standard Metaphor,Adapted Metaphor,Recent Metaphor,Original Metaphor;and seven strategies of metaphor translation,including reproducing the same image in the target language,replacing the image in the source language with a standard target language image,translation of metaphor by simile,translation of metaphor(or simile)by simile plus sense,conversion of metaphor to sense,deletion and same metaphor combined with sense.They can provide a strong theoretical support for analyzing the expressions of metaphors in novels and their translation methods.By deeply analyzing the expressions of metaphor and its translation methods in novels,it not only helps to understand the metaphorical meaning and cultural connotation of the original works,but also helps to explore the cultural differences and challenges faced by English and Chinese bilingualism in the process of metaphor translation,thereby significantly improving the translation level and promoting the development of translation research.

Materials and technology of Chinese jades dating to the Western Zhou period (1050―771 BCE)

Excavated jades dating to the Western Zhou period (1050―771 BCE) from the Xi’an area in Shaanxi Province, China, and contemporaneous jades in the collections of the Arthur M. Sackler Gallery at the Smithsonian Institution have been studied to learn about the jade and stone materials and how they were worked during the Western Zhou period. Materials identification was carried out using a combination of techniques such as Fourier-transform infrared spectroscopy and X-ray diffraction. Tool marks were studied using stereomicroscopy and examination of mold impressions using scanning electron microscopy. All of these objects were pro- duced through simple processes involving solid drilling, riffling, and sharp point abrasion; and no evidence was found for the use of rotary tools for incising or sawing.

W型铁氧体衍射叠合峰分峰拟合软件应用探讨

本文以溶胶凝胶-自蔓延法在不同温度下制备的W型铁氧体XRD衍射曲线为数据来源,选取其中有谷点、有肩点和完全重合3种类型的衍射叠合峰,分别采用Jade、Peakfit和Origin软件,对3类叠合峰进行分峰拟合,并从拟合准确性、绘图能力、专业性、适用范围、操作简易程度对3种软件的分峰拟合功能进行了对比分析。结果表明:origin软件不适用于完全重合叠合峰的分峰拟合,而Jade和Peakfit软件均可实现3类叠合峰的分峰拟合;origin在绘图和操作简易程度方面体现一定优势;Peakfit在适用范围及拟合准确性方面较具优势;而Jade在专业性、拟合准确性、适用范围方面能力均较为突出。

基于盲源分离的多域联合抗主瓣欺骗式干扰

主瓣欺骗式干扰增加了雷达对真实目标的检测难度,是雷达抗干扰领域的研究重点。文中就一种空域-极化域-多脉冲域联合的盲源分离算法进行了研究。该算法以特征矩阵联合对角化(Joint Approximate Diagonalization of Eigen-Matrices,JADE)盲源分离算法为基础,利用空域-极化域的角度相位差和多脉冲域的多普勒频率相位差分离出目标和干扰。首先,利用多个阵元的空域信息和极化域信息构建正交极化通道;然后,利用不同脉冲间目标和干扰径向速度差带来的多普勒频率差构建三域联合接收阵列;最后,将三域维度构造的数据作为盲源分离的输入,分离出目标信号和欺骗式干扰。计算机仿真验证,该算法可以在干扰完全淹没目标信号时,利用任意一个维度产生的差异成功分离出目标和干扰信号。

A Proposed Architecture for Local-Host and AWS with Multiagent System

Cloud computing has become one of the leading technologies in the world today.The benefits of cloud computing affect end users directly.There are several cloud computing frameworks,and each has ways of monitoring and providing resources.Cloud computing eliminates customer requirements such as expensive system configuration and massive infrastructure while improving dependability and scalability.From the user’s perspective,cloud computing makes it easy to upload multiagents and operate on different web services.In this paper,the authors used a restful web service and an agent system to discuss,deployments,and analysis of load performance parameters like memory use,cen-tral processing unit(CPU)utilization,network latency,etc.,both on localhost and an Amazon Web Service Elastic Cloud Computing(AWS-EC2)server.The Java Agent Development Environment(JADE)tool has been used to propose an archi-tecture and conduct a comparative study on both local and remote servers.JADE is an open-source tool for maintaining applications on AWS infrastructure.The focus of the study should be to reduce the complexity and time of load perfor-mance parameters by using an agent system on a cloud server instead of establish-ing a massive infrastructure on a local system,even for a small application.

冲绳海槽中部Jade热液活动区中块状硫化物的稀土元素地球化学特征

用ICP-MS对冲绳海槽Jade热液活动区中6个块状硫化物样品进行了稀土元素分析。除一个样品表现出极微弱的正Eu异常外(δEu=1.09),其他样品均表现出负Eu异常(δEu=0.58～0.71)和LREE相对富集((La/Yb)_N=1.29～47.87)的球粒陨石标准化配分模式。块状硫化物样品之间稀土元素组成的变化是由于热液流体-岩石的相互作用以及海水和热液流体不同程度混合的结果。与深海沉积物,火山岩和海水稀土元素配分模式对比,表明块状硫化物的REE部分来自沉积物和火山岩,海水的混合作用对块状硫化物的REE配分模式具有一定的影响。海底热液硫化物稀土元素组成的变化可以一定程度的反映出热液流体的演化特征。

冲绳海槽中部Jade热液活动区中海底热液沉积物的硫同位素组成及其地质意义

测定了冲绳海槽中部Jade热液活动区中18个热液沉积物样品的硫同位素组式，其中10个硫化物样品的δ34S值为5．2×10－3～7．2×10－3，7个硫酸盐样品的34S值为16．3×10-3～22．3×10-3，1个自然硫样品的δ34S值为8．2×10-3热液沉积物的硫主要来自中、酸性火山岩和海水，并且在流体与沉积物相互作用过程中海底沉积物也可能为热液沉积物的形成提供部分的硫．导致本区热液沉积物中硫化物与其他热液活动区的硫同位素组成不同的原因，主要是各热液活动区的硫源以及有关岩浆活动和构造演变的不同.海底热液体系中硫的演化是一个复杂的过程，涉及被加热海水的上升、流体与火山岩的相互作用、海水硫酸盐和中、酸性火山岩中流的混合作用以及流体与沉积物相互作周等一系列海底热液活动，其中海水和中、酸性火山岩的相互作用是本区硫演化的一个重要机制．
