    • 摘要: 为探究光量子辐照在低温条件下对淀粉回生的影响效果,以小麦淀粉为材料,经完全糊化后分别置于普通保鲜箱和光量子场保鲜箱中,研究光量子辐照在4℃下保藏20 d对糊化小麦淀粉回生作用的影响。采用TA.XT.Plus质构仪、体外消化性、差示扫描量热仪(DSC)、X-射线衍射仪(XRD)等仪器分析评价光量子辐照对淀粉回生的抑制作用。结果表明:4℃条件下,随着贮藏时间的延长,光量子辐照降低了淀粉凝胶的硬度,淀粉体系中快消化淀粉含量降低,慢消化淀粉含量增加,与对照组相比,淀粉结晶度降低了11.5%。由此可知,光量子辐照能在一定程度延缓淀粉回生,为光量子辐照保鲜淀粉制品提供依据。%To study effects of light quantum irradiation on starch retrogradation at low temperature , wheat starch which has been gelatinizized were stored in preservation box installed light quantum irradiation and non-light quantum irradiation at 4 ℃for 20 d, respectively. Indexes of starch retrogradation were measured by TA.XT. Plus Texture Analyzer, Differential Scanning Calorimetry (DSC), In Vitro Digestibility, and X-ray Diffraction (XRD). The results showed that the hardness of starch gel reduced together with the extension of storage time at 4℃compared with control, and the content of rapidly digestible starch in the starch system decreased and the slowly digestible starch increased. Meanwhile the crystallinity of the starch also decreased 11.5%than control group. Therefore the light quantum irradiation can delay starch retrogradation to some extent, which provides benefit to delay starch retrogradation with light quantum radiation preservation .

    • 摘要: As is well known, quantum optics has developed significantly in recent years and advanced several hot research topics, such as quantum communications, quantum sensing, quantum calculations, etc. Among these researches, it is important to understand the quantum information transmitting in optical fiber. For realizing longer transmission distance and better transmission quality, great effort has devoted to the researches of encoding and decoding at the transmitter and the receiver end. However, less attention was paid to the fading of signal in the transmission channel. In this work, we mainly focus on the transmission model of optical quantum transmission and the influences of loss, dispersion and nonlinear effect on fiber transmission of optical quantum information are also discussed. Quantum information transmission can be influenced by loss, dispersion and nonlinear effect in optical fiber, leading to transmission state evolution and energy transfer. Based on the transmission equation of single mode fiber and quantum theory of electromagnetic field, the fundamental mode field of single mode fiber is quantized. A quantum transmission equation is deduced from the classical optical transmission equation through quantizing the amplitude of electromagnetic field. Compared with classic wave theory, the photon transmission equation quantizing the slowly-varying amplitude in the coupled nonlinear Schrödinger equation is obtained. In the classic wave equation, light is interpreted as energy which propagates as waves. The photon transmission equation is obtained by quantizing the slowly-varying amplitude of light, that is, the particle nature of light. The energy propagates through alternative interaction between creation and annihilation operator on photons. The transmission equations show that photons will interact with the transmission medium during propagation and be influenced by dispersion, nonlinear effect, loss, etc. By giving a trail solution and introducing a perturbation term, the transmission equation is solved for the complicated case where the dispersion, loss and nonlinear effect are all involved. A dispersion equation that should be satisfied for nontrivial solution is then obtained. From this dispersion equation, the relation between photon power and perturbation frequency is calculated and analyzed. The change of photon power in generalized field with perturbation frequency is discussed, and the influences of fiber dispersion and nonlinearity on the solution are analyzed. Some conclusions are obtained by perturbed solution and analyses of single photon transmission equation in optical fiber. It is found that photon power decreases with the increase of perturbation frequency Ω and reaches its maximum value for zero perturbation frequency. At the same time, the optical power is affected by the dispersion of the optical fiber. Photon power decreases with the group velocity dispersion coefficient far from the zero dispersion point. It is also found that photon power decreases with the increase of nonlinear coefficient. This work may contribute to the research of the properties of quantum fiber transmission system.%量子信息在光纤中传输时,会受到光纤损耗、色散、非线性效应等多因素的影响,将产生传输态的演化与能量转移。本文以单模光纤传输方程以及电磁场量子化理论为基础,对单模光纤中基模模场进行量子化处理,推导并建立了考虑损耗、色散、非线性效应后的单光子传输方程。基于微扰法对单光子非线性传输方程进行了求解,给出了稳定解存在的必要条件及其所满足的色散方程。深入讨论了广域光功率随微扰频率的变化关系,并且分析了光纤色散、非线性效应对解的影响。为量子光纤传输系统性能的深入研究奠定了理论基础。
