零動壓 例句

1. If the velocity of atoms is near to zero, the light for ces will tend to confine the atoms near to nodes and antinodes. the stability depends on the magnitude of the negative slope of the light force, the depth of the potential well and the momentum diffusion coefficient. it is important to select the parameters, e. g
   如果通過激光冷卻能使原子速度降至很小甚至為 零 ，光 壓 力的作用將使原子被較穩定地囚禁于激光駐波場的節點和反節點處，其穩定程度取決于該處光 壓 力曲線負斜率的大小、對應勢能的勢阱深度以及 動 量擴散系數的大小，因此，如何在實驗中合理選擇激光強度、失諧量等顯得尤為關鍵。
2. 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。
3. Punching tool parts, blocks for edm, scissor parts, circular knives, machine parts, extruding tools, tools for diecasting pulverized materials, pressure plates, sliding parts, valve parts, embossing dies, cutter disks, planer knives for machining of wood, hard metal tipped tools, rolls for cold rolling mills
   沖 壓 工具 零 件、電火花機床的滑車、剪刀的刃口、環刀、機械 零 件、擠 壓 工具、硬模鑄造研磨材料的工具、承 壓 板、滑 動 零 件、閥門 零 件、 壓 花模、圓盤刀、木工中刨刀、切削硬金屬刀片、冷 壓 滾軸。
4. Traditional direct torque control uses two value torque regulator which makes zero voltage vector work long and make flux shape bad seriously and makes response time long when the speed of induction motor is very low or drops down quickly. in order to solve this problem the thesis puts forward a new way to use three - value torque regulator, when the motor speed is very low or drops down quickly, the contrary voltage vector is used instead of zero voltage vector and the between the stator flux and rotor flux is reduced quickly so that torque is reduced quickly and response time becomes shorter
   為此，本論文提出三點式轉矩調節，這樣當電機低速運轉或給定轉速突降時，不是加 零 電 壓 矢量，而是加反方向的電 壓 矢量，使定子磁鏈與轉子磁鏈之間的夾角迅速減小，從而使電磁轉矩也迅速減小，大大減小了調速時間，同時磁鏈值仍然保持基本恆定，輸出比較穩定的電磁轉矩，這在電機制 動 過程中非常有用。
5. The list betterments aimed at the properties of system : through the testing of dc voltage, pulse width and inverting voltage and frequency can be regulated online to fit for different steady load ; reducing speed ripples by compensating with nonzero voltage working proportional time ; adopting the technology of harmonics suppression. as a result, the high precision and wide speed control is realized and the step out is overcome
   針對系統的性能指標，做了如下改進：對直流側電 壓 的檢測，在線調整逆變器導通脈寬、輸出電 壓 和頻率，可以適應不同大小的恆負載；並用非 零 電 壓 矢量作用時間進行補償的方法，減小電機的低速脈 動 ；加入了諧波抑制技術等。
