查询词典 zero setting

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。

In mathematics , a division is called a division by zero if the divisor is zero . Such a division can be formally expressed as a /0 where a is the dividend. Whether this expression can be assigned a well-defined value depends upon the mathematical setting. In ordinary arithmetic, the expression has no meaning .

Deep autumn of setting sun, that low hill that go to many year agos of timespace pullouts, I am in setting sun the 静静 lookings at the remaining 辉, soon the small grass that wither away at nearby float shake, do not know is that tree ascends the leaf that drop down, from my in front float, I want to stretch hand to hold tight it, I want that again see it float the zero body the 姿, wanting to use my heart 暖 it the lifetime, but I have no, I did not stretch hand, selfish I let it is from I nearby float walk, a remaining for leaving I first individual being fond of 茫 lookinging at setting sun reflects shine on the earth, breeze not tight not slowly blow, the distant place spread the mineral area the broadcast in of song, break continuously and continuously come right away my ear the beside," probably tomorrow the sun the west descends the tired bird have returned, you will already step on old hour of the way home, life rare look for again mutually the companion that know, life finally difficult give up the very blue white cloud a remaining for" I in such deep autumn, setting sun in deep autumn I remembering this a few lyricses, autumnal winds bringing doing not calculate wonderful singing, however taking foliar feeling in autumn, setting sun reflect shine on my face, however the 勾 has the much more several remembering fondly.

深秋的夕阳，把时空拉回到多年前的那个山岗，我在夕阳里静静的看着余辉，快要枯萎的小草在身边飘摇，不知道是那棵树上掉下来的叶子，从我面前飘过，我想伸手去抓住它，我想再一次看看它飘零的身姿，想用我的心暖它一辈子，可是我没有，我没有伸手，自私的我让它从我身边飘走了，只留下我一个人迷茫的看着夕阳的余辉映照着大地，风不紧不慢地吹着，远处传来了矿区广播里的歌曲，断断续续的就来到我的耳旁，&或许明日太阳西下倦鸟已归时，你将已经踏上旧时的归途，人生难得再寻觅相知的伴侣，生命终究难舍蓝蓝的白云天&我在这样的深秋，在深秋的夕阳里我记住了这几句歌词，秋风带来不算美妙的歌声，却带走了秋叶的情，夕阳的余辉映照着我的脸，却勾起了几多的思念。
