Using the path integral method we derive quantum wave function and quantum fluctuations of charge andcurrent in the mesoscopic RLC circuit. We find that the quantum fluctuation of charge decreases with time, oppositely,the quantum fluctuation of current increases with time monotonously. Therefore there is a squeezing effect in the *** some more charge devices are used in the mesoscopic-damped circuit, the quantum noise can be reduced. We also findthat uncertainty relation of charge and current periodically varies with the period π/2 in the under-damped case.

We derive a formula of the nonadiabatic noncyclic Pancharatnam phase for a mesoscopic circuit with coupled inductors and capacitors. It shows that, because of coupling effect, the circuit is in squeezed quantum state initially, and the time evolution of Pancharatnam phase exhibits an oscillation in a complex way. Especially we find that when the capacity of the coupled capacitors is larger than that of other ones in the circuit, with the variation of time Pancharatnam phase becomes nearly periodic square-wave, which perhaps can provide a new approach for the realization of quantum logic gate.

因番茄斑驳花叶病毒(ToMMV)寄主范围广,传染性和致病力强,以ToMMV为对象,对其产生的植株病残体进行了病毒分布和存活时间检测、侵染活性分析以及传毒作用测试。结果表明:烟草植株病残体的叶、茎、根中均含有病毒,ToMMV可在病残体存活较长时间,病死枯叶室温存放90 d后病毒依然存在,且仍保持侵染活性,刀片刮划枯叶模拟农事操作接毒后发现病残体具有传毒作用;ToMMV可在病残体中长时间保持侵染活力,田间病残体很可能会成为下茬作物的初侵染源;土壤无直接传毒作用,但混有病残体的土壤也可成为初侵染源,且沾染在农具表面的离体病毒依然可以在一定时间内维持侵染活力,成为潜在的初侵染源。综上,清除植株病残体(减少初侵染源)是预防和控制ToMMV传播和扩散的重要环节,生产上应给予充分重视。

In order to preserve virus for identifying the resistance of rice varieties against rice black-streaked dwarf disease, a simple and reliable method was developed, through which virus-free small brown planthopper （SBPH） acquired rice black-streaked dwarf virus （RBSDV） from frozen infected leaves and the virus was transmitted to healthy rice plants. The experimental results showed that SBPH could obtain RBSDV from frozen infected rice leaves and the virus could be transmitted to a susceptible rice variety. For the ability to acquire RBSDV and transmit the virus to healthy plants by SBPH, there was no significant difference between frozen infected leaves and in vitro infected leaves. The novel method could be applied to identification of rice variety resistance to rice black-streaked dwarf disease, facilitating the breeding process for rice black-streaked dwarf disease resistance.

We demonstrate the controllable generation of multi-photon Fock states in circuit quantum electrodynamics （circuit QED）. The external bias flux regulated by a counter can effectively adjust the bias time on each superconducting flux qubit so that each flux qubit can pass in turn through the circuit cavity and thereby avoid the effect of decoherence. We further investigate the quantum correlation dynamics of coupling superconducting qubits in a Fock state. The results reveal that the lower the photon number of the light field in the number state, the stronger the interaction between qubits is, then the more beneficial to maintaining entanglement between qubits it will be.
