以保绿型玉米自交系齐319（Q319）和非保绿型玉米自交系黄早四（HZ4）为材料，采用大田和盆栽种植方式，研究了喷施外源激素6-苄氨基嘌呤(6-BA)对不同氮素水平下玉米花后叶片衰老特性的调控效应，为今后提高玉米产量提供理论和技术支持。主要研究结果如下：1.氮素处理对Q319和HZ4产量存在显著的影响，而6-BA处理对产量影响不显著，但氮素与6-BA互作极显著的提高了Q319和HZ4产量，氮素与6

Absorption and refrtion of the inner transition F2 (→) F3 of the closed four level N-type atom have been investigated under a weak field. The outer transitions
We propose an effective scheme for the entanglement concentration of a four-particle state via entanglement swapping in an ion trap. Taking the maximally entang

Based on the calculation of all the pairwise entanglements in the n(n≤6)-qubit Heisenberg ⅩⅩ open chain with system impurity, we find an important result: pa
