五种希格斯玻色子与希格斯场之内部结构模型图表解析

现今，“希格斯玻色子”被认为是所有基本粒子质量的来源，也是标准模型预言的最后一种粒子，目前，物理学家普遍认为不排除未来可能会发现其他带电荷的希格斯玻色子。许多物理学家认为：事实上，希格斯玻色子组成希格斯场是一种更加复杂的理论模型，而这些理论模型预言了应有五种不同的希格斯玻色子，它们不仅带有电荷，还有可能带有色荷，而且质量也不相同。希格斯场遍布在宇宙中，该文就这五种不同希格斯玻色子及其组成的希格斯场，作一理论模型预言之图表解析。

The Analysis and Improving of the Microwave Exciter in the Lower Hybrid Wave System

When we carry out lower hybrid wave heating and current driving plasma experiment at tokamak, we need mega-watt order of microwave power. The microwave signal at frequency of 2450 MHz is generated by a microwave exciter. According to the experiment＇s demands, the microwave exciter must provide output power of 1.5～ 2. 5 W with stabilized frequency and amplitude tobe used as the klystron input. Being amplified by the klystron, the microwave signal is transmitted through the transmitting system to the antenna and is emitted into the HL-2A tokamak. So we can see that the microwave exciter＇s function is very important to the lower hybrid wave heating and current driving plasma experiment.

We present a compact improved model of the magnetically insulated line oscillator with new-type beam dump and other novel features. In the experiments, high-power microwave of the TM01 mode is generated from the device with a frequency range of 1.73-1.78 GHz and a peak power level of above 2 GW, when the diode voltage is taken in the range 520-540kV, and the diode current is in the range 58-62kA. This confirms the simulation results.     

在高密度下核物质的色超导性

建立了相变热力学理论和场论的关系. 强调在量子场论中必须引进序参量场， 则相变的讨论就类似于Goldstone bosons 的产生. 如果只讨论一级相变， Goldstone bosons场就足够了; 如果要讨论二级相变， 则必须讨论一系列的场， 这些场构成一个对称群的表示. 另外, 也将这一思想用到色超导中. In this paper we built a relation between the thermodynamical theory of the phase transition and field theory. We emphasized that in the quantum field theory we have to introduce the order parameter fields. Then the discussion of the phase transition is closed to the creation of the Goldstone bosons. If we only discuss the first order transition, the Goldstone bosons fields are sufficient. If we want to discuss the second order transition, we have to discuss a set of fields that constructs a representation of a symmetry group. We also apply this concept to color superconductivity.     

用符合计数研究“钚的质量属性”与“氧化钚不存在属性”

符合计数的测量量为总中子计数和符合计数，而未知量有（α，n）中子与自发裂变中子之比α、泄漏增殖系数M1以及钚-240的质量。符合计数与源中子泄漏复度分布的二阶矩成正比。对MCNP程序进行修改，加入自发裂变源与（α，n）中子源的跟踪功能，直接得到了中子泄漏复度分布的二阶矩。     

A modal analysis for the acoustic radiation problems, Ⅱ. Examples

The acoustic radiation modes and the field distribution modes describe the radiation patterns of a complex vibrating surface and the field distribution patterns respectively. The physical meanings of the acoustic radiation modes and the field distribution modes are revealed by numerical method. For a sphere body, a spinning body and a rectangular body, the geometrical patterns of the acoustic radiation modes and the field distribution modes are given. The radiation mode 1 represents the radiation behavior of a monopole radiator, the radiation modes 2 through 4 represent the radiation behavior of dipole radiators respectively, and the radiation modes 5 through 9 represent the radiation behavior of quadrapole radiators respectively. The acoustic radiation modes and the field distribution modes introduce the multi-pole decomposition method into discussion of the acoustic radiation problems.
