Locality in the Everett Interpretation of Quantum Field Theory

Recently it has been shown that transformations of Heisenberg-picture operators are the causal mechanism which allows Bell-theorem-violating correlations at a distance to coexist with locality in the Everett interpretation of quantum mechanics. A calculation to first order in perturbation theory of the generation of EPRB entanglement in nonrelativistic fermionic field theory in the Heisenberg picture illustrates that the same mechanism leads to correlations without nonlocality in quantum field theory as well. An explicit transformation is given to a representation in which initial-condition information is transferred from the state vector to the field operators, making the locality of the theory manifest.     

轨道嵌套多像全息记录

根椐椭圆的性质，介绍了将大小不同的椭圆按一定的约束条件形成轨道嵌套多像全息记录的方法。这种方法利用全息台在实验室里可进行多像全息记录，避免了实验时为了调节物光与参考光光程相等所带来的反复测量光程的麻烦，实现把同一时刻空间分离的若干物体或一个物体不同视角的信息同时记录在一张全息图上，得到这些物体的三维全息图，即全息图片上同时再现出多个物体的像，或一个物体不同位置的视图的合成。

一种加热炉炉管表面红外检测温度的修正方法

加热炉炉管表面温度检测的准确性直接关系到加热炉的运行状态和生产安全,利用红外热像仪测量炉管温度时易受到火焰和烟气、邻近炉管、炉墙辐射等因素的强烈干扰。为了实时准确获取炉管表面的真实温度,以某炼油厂加热炉为例,首先给出了炉管表面热红外检测温度的干扰分析,进而提出一种基于现场参数的实时温度校正模型,并结合该模型给出一套判别某厂加热炉炉管状态的专家规则,最后将这套软件应用于实际工程检验。研究结果表明,该方法有效实现了炉管表面的温度修正。

为了解决图像真伪的智能语音判读问题,提出了一种基于数字水印载体的图像语音判读方法,方法首先预存储防伪语音信息特征,而后将语音信息分解成语音符号信息以数字水印为载体嵌入到图像内部,提取复原后由专用的语音合成系统进行发音并与先前特征进行比对,进而实现判读。实验验证了方法的有效性,方法的实现使图像具备了语音校验能力和语音真伪智能判别能力。     

Transverse mass distributions in central heavy-ion collisions at high energies

The transverse mass spectra of protons, pions, kaons, Lambda and Antilambda produced in cen- tral nucleus-nucleus collisions at high energies are described by using one-temperature and two-temperature emission pictures. The calculated results are compared and found to be in good agreement with the experimen- tal data of the E895, E866 and E917 Collaborations measured in central Au-Au collisions at the Alternating Gradient Synchrotron (AGS) energies and the NA49 Collaboration measured in central Pb-Pb collisions at the Super Proton Synchrotron (SPS) energies. It is demonstrated that the transverse mass distributions of protons, kaons, Lambda and Antilambda, except for Lambda hyperons produced in central Pb-Pb collisions at 158 A GeV, can be described by using the one-temperature emission picture, and for pions, we need to use the two-temperature emission picture.     

Knotted pictures of the GHZ states on the surface of trivial torus

By means of the method of torus knot theory, this paper presents the complete process of obtaining the knotted pictures of eight GHZ states on the surface of trivial torus from the knotted pictures of eight basic three-qubit states on the surface of trivial torus. Thus, we obtain eight knotted pictures 12₁ linkage on the ordinary plane.
