为探究重金属胁迫下农作物污染响应的敏感叶型及谱段,设计了室外温室环境下的不同铜胁迫梯度玉米花盆试验。以玉米叶片为探究对象,利用仪器测定了出穂期玉米叶片的高光谱反射率数据以及叶片中重金属含量数据,为研究提供了基础数据。从频率域角度,结合时频分析的方法设计了叶片光谱探测法(LSDM),获得了重金属铜胁迫下敏感叶型及谱段,为农作物重金属监测提供技术支撑。根据玉米的生长过程,从老叶(O)、中叶(M)、新叶(N)光谱350~1300 nm的全谱段和子谱段角度进行探究。(1)对铜胁迫下玉米叶片的高光谱反射率数据进行双微分(SOD)和包络线移除(CR),转换到频率域上,结合时频分析的方法进行Daubechies小波6层分解。(2)根据信号异常点、小波高值点和SODCR曲线高值点,定义玉米叶片的光谱异常参数(SAP)。异常变化反射率ACR(异常反射率与其后一个相邻波段反射率差值的绝对值);异常小波系数AWC(异常小波系数与其后一个相邻波段小波系数差值的绝对值);异常SODCR值ASV(异常点SODCR值与其后一个相邻波段SODCR值差值的绝对值)。通过光谱异常参数与玉米叶片重金属含量的相关关系,探究对铜污染响应敏感的叶型及谱段。结果表明,叶片光谱探测法LSDM能高效地对玉米叶片弱信息进行增强,并准确定位出重金属铜胁迫引起的光谱异常谱段位置,异常变化范围集中在350~800 nm内;光谱异常参数能定量地衡量玉米叶片在重金属铜胁迫下的光谱异常;在不同铜胁迫梯度下,玉米新叶(N)为敏感叶型,敏感谱段为蓝边、绿峰、黄边、红谷。该研究有望为其他谷类农作物及其冠层尺度重金属监测提供技术支撑。

The Rayleigh distillation isotope fractionation(RDIF) model is one of the most popular methods used in isotope geochemistry. Numerous isotope signals observed in geologic processes have been interpreted with this model. The RDIF model provides a simple mathematic solution for the reservoir-limited equilibrium isotope fractionation effect. Due to the reservoir effect, tremendously large isotope fractionations will always be produced if the reservoir is close to being depleted. However, in real situations, many prerequisites assumed in the RDIF model are often difficult to meet. For instance, it requires the relocated materials, which are removed step by step from one reservoir to another with different isotope compositions(i.e., with isotope fractionation), to be isotopically equilibrated with materials in the first reservoir simultaneously. This ‘‘quick equilibrium requirement’’ is indeed hard to meet if the first reservoir is sufficiently large or the removal step is fast. The whole first reservoir will often fail to re-attain equilibrium in time before the next removal *** problem led the RDIF model to fail to interpret isotope signals of many real situations. Here a diffusion-coupled and Rayleigh-like(i.e., reservoir-effect included) separation process is chosen to investigate this problem. We find that the final isotope fractionations are controlled by both the diffusion process and the reservoir effects via the disequilibrium separation process. Due to its complexity, we choose to use a numerical simulation method to solve this problem by developing specific computing codes for the working *** to our simulation results, the classical RDIF model only governs isotope fractionations correctly at the final stages of separation when the reservoir scale(or thickness of the system) is reduced to the order of magnitude of the quotient of the diffusivity and the separation rate. The RDIF model fails in other situations and the isotope fractionations

慢性心力衰竭恶性心律失常发病率、致死率高,严重影响心力衰竭患者生活质量。心肌细胞离子通道异常导致动作电位时程(APD)延长,进而诱发异常触发活动是心力衰竭心律失常发生的主要机制。瞬时外向钾电流(I to)主要参与心肌细胞动作电位(AP)的1期复极,对心力衰竭时APD延长具有重要作用;钾通道相互作用蛋白2(KChIP 2)是I to通道上的的重要功能亚单位,对I to具有关键性调控作用,KChIP 2基因敲除大鼠心肌细胞I to几乎完全消失,心律失常易感性显著增加。本文对慢性心力衰竭心律失常的钾离子通道机制研究进展进行综述,以期为心力衰竭心律失常的治疗靶点提供思路。
