Evaluating calibration strategies for isotope ratio infrared spectroscopy for atmospheric 13CO2/12CO
Isotope ratio infrared spectroscopy (IRIS) provides an in situ technique for measuring δ13C in atmospheric CO2.A number of methods have been proposed for calibrating the IRIS measurements, but few stu

氮气和/或氧化亚氮在沉积物中通过反硝化、厌氧氨氧化或是硝化产生.这些过程错综复杂,使人们无法准确估算每个生化过程单独产生气态氮的速率.近年来,经典的同位素配对技术(IPT),即最常用的添加15N-NO3-以定量反硝化的方法,在本文中,作者对上述方法进行了改进.作者安装了低温捕集器对N2和N2O进行预浓缩,从而同时测得一个样品产生的两种气态产物.对N2(核质比:m/z=28,m/z=29及m/z=3

本文分析了飞轮储能系统易发生的四种电气故障,提出了改进的各相电流独立控制的容错拓扑.对比传统的电机中性点与逆变器直流端中点相连的容错拓扑,改进的拓扑在发生驱动电机绕组开路故障或逆变器器件单管发生开路、短路故障的情况下,系统仍能持续稳定地运行.本文对提出的容错拓扑及控制策略做了详细分析并给出仿真结果.
首次提出了Boost型高频环节AC-AC变换器电路结构与拓扑族,它是由储能电感、输入周波变换器、高频变压器、输出周波变换器以及输入、输出滤波器构成.深入分柝研究了这类变换器的稳态原理特性与移相控制策略,提出并有效地解决了变换器的若干关键问题.以全桥桥式电路拓扑为例,进行了这类变换器的仿真和原理试验.研究结果表明,这类变换器具有高频电气隔离、电路拓扑简洁、两级功率变换(LFAC-HFAC-LFAC)
