In this work, we employ the Bethe-Salpeter （B-S） equation to investigate the spectra of free diquarks and their B-S wave functions. We find that the B-S approach can be consistently applied to study the diqaurks with two heavy quarks or one heavy and one light quarks, but for two light-quark systems, the results are not reliable. There are a few free parameters in the whole scenario which can only be fixed phenomenologically. Thus, to determine them, one has to study baryons which are composed of quarks and diquarks.

以某型号工程车辆为研究对象,针对其工况特点,以闭锁控制原理为基础,计算并选择在不同油门开度下的常用闭锁点。以油门开度和涡轮转速为基础,以制动信号、档位信号和冷却水温度信号为辅助,设计了多参数闭锁控制策略,并建立了相应的闭锁流程。运用MATLAB/Simulink软件建立了由闭锁控制模型、发动机模型、液力变矩器模型、液力变矩器输出模型、变速箱模型和外界阻力模型组成的整车模型,并对整车模型进行仿真。仿真结果表明:闭锁信号能对水温与档位信号做出正确响应,车辆在设定的闭锁点处实现闭锁;闭锁控制模型符合制定的闭锁控制策略,且其传动系统的输出模型符合实际工况,为车辆的闭锁控制提供了理论依据,也为车辆传动效率的提高与车辆节能减排提供了一种新方案。

在利用大亚湾中微子实验装置研究超新星中微子探测过程中,需要考虑到中微子传播过程中受到各种效应的影响,包括超新星震荡效应、中微子集体效应、Mikheyev-Smirnov-Wolfenstein(MSW)效应和地球物质效应等。由于超新星中微子受到这些效应,不同味道的中微子之间振荡会发生变化,因而利用探测某些超新星中微子事例数之比,就有可能确定中微子的质量层次,得到中微子混合角θ13和中微子绝对质量的信息。

Nonadiabatic holonomic quantum computers serve as the physical platform for nonadiabatic holonomic quantum *** quantum computation has entered the noisy intermediate-scale era, building accurate intermediate-scale nonadiabatic holonomic quantum computers is clearly necessary. Given that measurements are the sole means of extracting information, they play an indispensable role in nonadiabatic holonomic quantum computers. Accordingly, developing methods to reduce measurement errors in nonadiabatic holonomic quantum computers is of great importance. However, while much attention has been given to the research on nonadiabatic holonomic gates, the research on reducing measurement errors in nonadiabatic holonomic quantum computers is severely lacking. In this study, we propose a measurement error reduction method tailored for intermediate-scale nonadiabatic holonomic quantum computers. The reason we say this is because our method can not only reduce the measurement errors in the computer but also be useful in mitigating errors originating from nonadiabatic holonomic gates. Given these features,our method significantly advances the construction of accurate intermediate-scale nonadiabatic holonomic quantum computers.

SELEX合作组发现的DsJ(2632)引起了很多的讨论,同时也带来了激烈的争论．它的自旋宇称还没有最后确定,如果它真的存在,它的夸克结构可能是奇特的．以前有的文献假定DsJ(2632)是1-的径向激发态,我们假定它可能是夸克结构为qq,JP为2+的基态或者0+DsJ(2317)的第一径向激发态,用Bethe-Salpeter方程重新计算了它的衰变宽度．计算结果表明,理论值和实验数据还是存在尖锐的矛盾．
