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。

Based on the point spread function of holographic system, the lateral resolution of digital holographic imaging system without any pre-magnification is studied.

Leslie: I thought I saw your pupils dilate when you looked at her.

你看她的时候瞳孔放大。

Look for dilated pupils and a rise in vocal pitch.

留意瞳孔的放大及声调的突高信息是必要的。

Christensen says, One of my pupils got stuck in the dilated position...

克里斯腾森说："我的一个瞳孔固定在放大状态……我不得不去了医院。"

A very useful tool for scale -up is the dimensionless group.

在放大中使用的一个很有用的工具是无量纲数群。

The conventional process for the synthesis of rubber antioxidant 4020 from the 4-anino diphenylamine and methyl isobutyl ketone under high pressure can be replaced by a new three-step process using p -aminophenol, methyl-isobutyl ketone, formic acid and aniline as raw materials.

We also study the CP-violating asymmetry in nonleptonic decay Λ→ pπ. By employing the Skyrme model to calculate this decay amplitude contributed by the gluonic diploe operator, we find a possible large CP-violating asymmetry could be expected, which is consistent with the previous study.

在计算supersymmetricextensions of the standard model中Λ→pπ衰变过程中CP破坏不对称性时，我们使用了Skyrme模型计算了其中关于强子振幅部分，结果显示相对于标准模型的预言有较大的放大效果，这个结果和前人研究结果一致。

Many inclusions are not discernable to the naked eye and require magnification to become apparent.

很多包括不是对肉眼的discernable并且要求放大变得明显。
