與一般的建築空調相比，汽車空調的工作環境惡劣，條件差，控制難度要增加很多，主要體現在以下幾個方面：一是車外熱負荷變化大，難以確定控制參數；二是要求空調負荷大，而且要控制空調使其降溫迅速：三，不便於用電力作為動力源，必須用汽車發動機或輔助發動機來帶動壓縮機，當採用汽車發動機作為動力源時，由於汽車的車速變化大，發動機轉速的變化可從600r min到4000r min ，壓縮機轉速與發動機轉速成正比，其轉速變化高達7倍，給空調系統製冷劑流量控制帶來困難。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

斜緩維持波形的特徵為其電壓上升時間較傳統波形增加了三倍左右，其有助於降低氣體放電時的空間電壓差和累積足量的壁電荷以維持腔體中氣體放電作用得以連續產生的效果。Although each light dish slice situation for pressure for big factory all not speech, this year dvd - r light dish slice containing price drop, in fact, current the united states ce consume electronics exhibition, already appearing a price mess, however, the big factory all mean, on the other hand, the dvd demand quickly promote, although the price drop, the factory measure empress, earning, accrual will still increase ; on the other hand, big factory will then announce new products, the light dish that higher times are soon slice, increase to compete the threshold, then reduce to reduce price to impact factory earning, accrual. because of the dvd light dish slice period for of technique, funds. etc
雖然各光盤片大廠均不諱言，今年dvd - r光盤片有跌價的壓力，事實上，目前美國ce消費電子展，已出現通路品牌光盤片價格紊亂的情形，不過，大廠均表示，一方面， dvd需求量快速提升，雖然價格下滑，但是廠商擴量后，營收獲利仍將正增長另一方面，大廠將以推出新產品，更高倍速的光盤片，提高競爭門檻，以減少殺價對廠商營收獲利的沖擊。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。Voltage tripler circuit
三倍增壓電路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
