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。

Although the voice-length of the neutral tone syllable is very short, the tone pattern can be perceived. The neutral tone pitch has two types; I .the neutral tone words can be read in brief, low-drop tone when they appear behind the ~ tone, the 2nd tone and the 4~ tone, the tone pitch is 31; the neutral tone words can be read in brief, half rd high-smooth tone.

关于轻声的调值，目前学术界有两个比较有代表性的观点：1、认为轻声在四个声调之后的音高各不相同。2、认为轻声音节尽管音长短，但它的调型仍然可以感知，调值可归纳为两种情况：（1）轻声在第一声、第二声、第四声后读短促的低降调，调值拟为31。

Ancient times the Babylon civilization located the environment belonged to the subtropics desert climate, but benefitted from two rivers, young sent pulls the bottom river and the Tigris River mother's gracious gift, was having the exceptionally broad impact plain, but by was in the arid few rain in the middle of the desert climate, on the one hand thus created the local wooded area to be very few, on the other hand was the great plains which so stretched to the horizon smoothly like baffles, from this has become the sierra absolute forbidden area, from this occupied the plain center region people, even if wanted to use the firm stone material, also could because was far away, either was gives way before difficulties looks Shi Xing to sigh, either was after pays the extremely soaring price, shipped in by farSeveral stones only can use in actually carving the magnificent precious tombstone, even was in some plain person all not once has seen the mountain appearance for a lifetime, in brief took root in two river basin Cuban Billen civilization, finally is framed was the soil texture civilization, they created the cuneiform character, all could not but engrave above the thin clay tablet, was recording the exceptionally precious history, obviously in the different region humanity, all was influences subtly sparely no effort regarding the side each kind of environment resources use.

古代巴比伦文明所处的环境属于亚热带沙漠气候，但得益于两条河流，幼发拉底河与底格里斯河母亲般的恩赐，拥有着异常广阔的冲击平原，但由处于干旱少雨的沙漠气候当中，从而造成一方面当地森林面积很少，另一方面就是如此一望无垠平坦如砥的大平原，由此成了山脉的绝对禁区，由此处在平原中心区域的人们，即使想使用坚固的石头材料，也会因为路途遥远，要么是知难而退望石兴叹了，要么是在付出极为高昂的代价后，远远运来几块石头却只能用于雕刻华丽珍贵的墓碑，甚至是有些平原中的人一辈子都不曾见过大山的模样，总之植根于两河流域的古巴比伦文明，最终被定格为土质文明，就连他们所创造的楔形文字，都不得不刻印在薄泥板之上，来记载着异常珍贵的历史，可见不同区域内的人类，对于身边各种环境资源的利用都是潜移默化不遗余力的。

Take as a single example this easily overlooked little passage from the rondo of the 23rd piano concerto; it is, in its essence, nothing more than a functional bit of connective tissue taking us from one place to another within the movement's structure. Ten brief bars—about 10 seconds—of basic scalar material, doing its job efficiently and economically. But it is at the same time so richly and amusingly characterized, so full of piping energy, with its determined but struggling piano line climbing its stutteringly inexorable way up to the note E, punctuated along its course by deadpan commentary from the winds, sneaking in the D natural that signals the change of key with almost undetectable sleight of hand—the passage almost constitutes a miniature comic universe all by itself.

请听这段在《第23钢琴协奏曲》中常常被人忽视的回旋曲( http：//img.slate.com/media/87/7_mozart488.asf )，没有哪个功能性连结段能比它更好地仅通过乐章结构就将听众带入另一个世界，长约10秒钟的概要部分(brief bars of basic scalar material)不仅经济有效地发挥其职能，同时又表现出丰富、诙谐的特色，充满木管乐器的活力，伴随着坚决但阻碍不断的钢琴的快速音群移入E大调，其行进过程不时被管乐器部加以修饰、注解，自然而然的转为D大调，转调手法之娴熟几乎无法察觉——这段音乐本身创造出一个微缩的喜剧世界。
