A novel parallel - serial type cttfc ( combined two - transistor forward converter ) with coupled inductor is present in this paper, and the performance of three parallel - serial type cttfcs is studied and compared. the performance of cttfc with coupled inductor is similar to the other two cttfcs while coupling coefficient is less than one and the converter working ccm ( continuous current mode ), and input - to - output voltage gain increase one times while coupling coefficient is one
本文提出了一種耦合電感並?串型雙管正激組合變換器，並對三種並?串型組合變換器的特性作了比較：耦合系數小於1且耦合線圈電流連續時，三種並?串型組合變換器特性相類似：耦合系數為1時，組合變換器輸入輸出電壓增益增大一倍。Discuss the method to improve the efficiency of collecting signal and signal - noise ration. make the setup of detection device, high voltage supply of pmt and low - noise preamplifier ; doing lif detection experiment to green fluorescent dye
詳細討論了提高熒光採集效率和信噪比的措施，製作了探測機構、光電倍增管的高壓供電電路和前置放大器。The optimized experimental conditions are determined and the densities of some elements in the mental alloy standard samples are measured. the experimental results shows that the spectral intensity of the plasma enhances significantly with the increase of the operating voltage and the power density. ( 1 ) to the steel ally sample, the emission intensities of the spectra reach to the maximum values when the laser operating voltage is 1600v and the argon pressure is 600 torr. under the same pressure, the spectral intensity of the plasma in the argon atmosphere is stronger than that in the air. when the argon pressure is 320 to rr, the signal - noise ration is about 5 times than that which the argon pressure is 700 torr, but the temperature of plasma is less about 1000k
（ 1 ）對于光譜標鋼準樣品，當激光器工作電壓為1600v 、氬氣壓力為600乇時，譜線強度達到最大，並且在相同壓強下，氬氣中的等離子體與空氣中的等離子體相比，其輻射強度明顯增強；氬氣壓力為320乇時的譜線信背比約為600乇條件下的5倍，而等離子體溫度卻下降了近1000k ，即等離子體溫度隨環境氣壓的增大而增大；當激光束的焦斑在樣品表面上下移動時，激光誘導量、等離子體的激發溫度、譜線強度都呈不對稱性分佈，其最大值對應的焦斑位置都位於樣品表面之下0 . 4mm左右。The common detector output pulse signal scope is several dozens millivolts, but the multichannel pulse analyzer input pulse amplitude request is 1 - 15v, therefore the pulse linear amplifier must have the certain voltage gain, about ten times to several times
一般探測器輸出脈沖信號幅度為幾十毫伏，而多道脈沖幅度分析器輸入脈沖幅度要求為1 - 10v ，所以脈沖線性放大器必須具有一定的電壓放大增益，為數倍到上百倍。But in fact, there are many windings on each leg of a balance transformer, and the winding impedance relationships that the balance condition requires are strict, so it is difficult to design and make such transformers. if adopting the connection scheme of dual windings, the windings on single leg will increase almost doubly. it is more difficult to satisfy the balance condition and probably it will confront conflict when arranging these windings, so parameters of various phases can not be balanced
事實上由於平衡變壓器單柱繞組數目較多，若採用雙重接線方案，則單柱繞組數目增加近一倍，滿足平衡條件十分困難，甚至使得繞組在空間上的布置產生矛盾，無法達到各相參數平衡的要求，而「四相四心柱「結構的三相變四相電力變壓器較好的解決了這一難題。We adopt double alkali cathodal tube 9789qb, which was made by emi corporation in england, as our photomultiplier, whose spectrum ranges between 300nm to 650nm, with less noise counters and single - photon apices, which make it suitable as a single - photon - counter. the disparted - voltage device is designed in a reasonable way and the cooling system of iquefied nitrogen which makes it small in size, simple in structure, easy in processing, cheap in cost and good in performance
該管型的光譜范圍在300 650nm ，具有暗計數少，有單光子峰的特點，適于做單光子計數器；本文的光電倍增管分壓器設計合理而冷卻系統採用液氮，該系統體積小、結構簡單、加工便利、成本低廉且性能良好。The article mainly discusses the circuit of electric pressure multiplier and its stability at the changes of electric current and electric pressure of the power
