According to the demand of high magnetic field power supply, reference is increased with a set ramp rate and stops at a set stable value, so reference system is composed of digital setting and digit to analog converting circuit. But the stability of reference is mostly guaranteed by the performance of D/A circuit, so D/A circuit is particularly studied in reference system. The scheme of D/A circuit, the selection of DAC and its voltage reference, hardware anti-jamming design and PCB design are discussed in detail, and software of remote control and PLC are discussed in brief. Zero-flux DC current transformer well satisfies the demands of the high stability of Load current detection unit, so the principle of zero-flux DC current transformer is analyzed; in the mean time a project which detects the long term stability is designed. During 8 hours, analog signal which is detected with high precision digit multimeter is recorded in computer at 1HZ frequency by GPIB communication. The drift error source and related parameters are explained in the compare-amplify part. Detailed subtraction circuit is designed; also amplifier chip and periphery components are selected and verified according to the theory of error analysis.
根据强磁场电源的需求,参考源应按照软件设定的斜率逐渐上升到设定稳态值,则参考源系统应由数字给定和数模转换电路两大部分组成,而参考源的稳定度主要依靠完成数模转换功能的模拟电路的性能来保证,因此本文对参考源系统的研究以数模转换电路为重点,分别从电路方案的确定、数模转换芯片及其基准电压源的选取和验证、电路板硬件抗干扰和PCB设计几方面进行了论述,然后对数字给定部分的远控组态和PLC程序设计作了简要介绍;采用零磁通原理的直流电流转换器很好地满足了对负载电流检测单元高稳定度的需求,本文详细分析了零磁通检测的原理,并在选定此种类型电流转换器的基础上设计了一套检测长期稳定度的方案,8小时内以1秒为采样周期,通过计算机Labview程序和高精度数字电压表的GPIB通讯,将被高精度数字电压表数字化后的模拟信号采样值连续记录至计算机中;比较放大环节简要阐述了漂移产生的原因和相关参数指标,确定了具体的减法电路形式,并根据误差分析理论对运算放大器和外围元器件进行了选取和验证。

The basal diameter, height of aerial stem, leaf length at middle stem, leaf width at middle stem, internode length at middle stem, internodes number and panicle length of 30 plants from every population were recorded. The statistics of morphological characters showed that the distribution trends of the averages of morphological characters are similar among populations. However, the coefficients of variation within population of 7 morphological characters were very different. The CV of internodes was largest and the CV of height was smallest within population. F-statistics showed that the differences of all morphological characters among populations were significant (P.01). But the differences among populations were different between different groups. The cluster analysis proved that all populations could be divided into three types: salty reed, freshwater reed and giant reed.
对来自每个种群的30个个体的基径、株高、中部叶长、中部叶宽、中部节间长、节间数、穗长7个形态特征的统计分析表明:各形态特征平均值在种群间的分布趋势相似,但变化幅度不同,株高、叶长等营养特征变化较大大,生殖特征穗长的变化较小;7个形态指标在种群内的平均变异度从大到小依次为中部节间长、中部叶宽、穗长、中部叶长、基径、节间数、株高,种群内的平均形态变异度与生境异质性有关;7个形态指标在种群间均差异显著,但多重比较分析显示显著差异主要存在于BZH、淡水生境种群和盐渍化生境种群之间,在相似生境种群间的形态差异不显著;以形态特征为依据的聚类分析支持将15个种群分为三类:盐生芦苇、淡水芦苇和巨型芦苇。
