正向阻斷 的英文怎麼說
中文拼音 [zhēngxiàngzǔduàn]
正向阻斷
英文
forward blocking /conducting-
For electrodeposition by dc methods, the metals deposite uninterrupted and the particles were also embeded uninterrupted into the coatings ; for electrodeposition by pc method, the particles with biggish volume were desorbed from the coatings and returned to the electrolyte again owing to the presence of pulse interval ; for electrodeposition by prc method, the particles carried positive charges are much more easy to desorb from the coatings owing to the effecf of reverse pulse current combined with pulse interval, in addition, the reverse pulse current also could dissovle the metals, further accelerates the desorption of particles, thus the particles size embeded in the coatings by prc method is the least
直流電沉積時,基質金屬的沉積連續進行,粒子在電極表面不間斷嵌入鍍層;單脈沖電沉積由於脈沖間歇的存在使得具有較大體積的粒子會脫附,重新回到溶液中;採用周期換向脈沖時,反向脈沖電流使表面荷正電的較大的粒子更易從電極表面脫附,同時,反向脈沖電流對基質金屬的溶解作用,也會促進粒子的脫附,因此鍍層中復合粒子尺寸最小。隨著鍍層中粒子復合量的增加,三種鍍層的晶粒都明顯細化,說明al _ 2o _ 3的存在阻止了晶粒的長大,提高了電沉積過程中晶核的形成速率。1 m 0. 5, the phase - shifted angle 6 is controlled in term of sine law which makes the magnitude of resonant voltage track a reference sine voltage, and the resonant voltage is rectified, filtered, inverted and then the better sine - voltage output is obtained, theoretical analysis and experimental results show that for the resistive load and inductive load, the switches of leading leg of the phase - shift - controlled circuit are always turned on at zvs, and ones of lagging leg are turned on at zvs ( < 0 ) or turned off at zcs ( ( > 0 ), moreover, all switches in the low - frequency inverter are always turned on and off at zvs, the measured circuit efficiency for rated load reaches up to 88 %
從功率單向流動角度出發,提出了一種lcc諧振型恆頻移相單相高頻鏈逆變電路拓撲,在調制系數0 . 1 m 0 . 5情況下,控制移相角按正弦規律變化,使諧振電壓脈沖列的幅值追蹤參考正弦電壓信號,經過整流、濾波、低頻逆變,從而獲得正弦度較好的輸出電壓。理論分析和實驗結果證明對于阻性負載或阻感性負載,移相全橋具有超前橋臂零電壓開通,滯后橋臂或者零電壓開通( _ 0 )或者零電流關斷( _ 0 )的軟開關特性,而低頻逆變器的各個開關均實現零電壓條件下的開通與關斷。Insensitivity to eth ( in eir1 - 1 root and etr1 - 3 ) led to the impossibility of iaa transportion from shoot tip to shoot bottom or root, so that result in the diminishment of root gravitropism

( 2 ) in order to ensure normal work of flue system in lead column in the course of zinc refining, theoretic calculation and measure about the flow resistance of exhaust gas are carried through. the results of study reveal that drawing out force of chimney is inadequate, which is mainly caused by illogicality of flue construction
在研究過程中,採取了現場實測和數值模擬手段對韶關冶煉廠鋅精餾鉛塔燃燒室及排煙系統進行了綜合診斷,具體結果包括如下: ( 1 )完成鋅精餾鉛塔燃燒室內溫度測試以及燃燒狀況的測試,結果發現:鉛塔燃燒室內水平方向的煙氣溫度並非均勻,而且其溫差比上下方向的溫差更大,以及鉛塔燃燒室尾部存在co未燃燼問題; ( 2 )為了保證鉛塔煙氣系統的正常工作,對煙道系統的阻力進行了理論計算及測試分析,結果發現:鋅精餾鉛塔煙氣系統中煙囪抽力不夠,這主要是煙道結構不合理所造成的。When basement rock rupture pass through the well cross section, the fracture belts can be identified with some evidences, for example, the compensate neutron increasing and the stratum density diminishing synchronization, the dual - laterolog resistance diminishing greatly and the positive difference between the deep laterolog resistance and the shallow laterolog resistance appearing. when the compensate neutron increase, the stratum density diminishing and the dual - laterolog resistance value diminishing slightly, the fracture belts can be confirmed with the intrusive vein at high frequency in well cross section
當有基巖斷裂在井削麵上通過時,若補償中子增大與地層密度變小同步發生,雙側向測井電阻率有明顯變低並有正差異出現,則可以判別為裂縫發育帶;當補償中子增大,地層密度變小及雙側向幅度變小都不太明顯時,則可以利用井剖面中頻繁出現的侵入巖脈來確定裂縫發育段。This allows the gate to regain control in order to turn the device on at some controllable time after it has again entered the forward blocking state
這樣,當晶閘管重新處于正向阻斷狀態(器件處于可控時間) ,使得門極變得可控。The thyristor can be trigged into the on - state by applying a pulse of positive gate current for a short duration provided that the device is in its forward blocking state
