  1. Our previous studies demonstrated that agmatine not only reduced the amplitude of action potential ( apa ), maximal rate of depolarization ( vmax ), velocity of diastolic ( phase 4 ) depolarization ( vdd ), and rate of pacemaker firing ( rpf ), but also prolonged 90 % duration of action potential ( apd90 ) in a concentration - dependent manner

    我們先前的實驗證明，胍了胺可劑量依賴性地抑制兔竇房結起搏細胞的0相最大上升速度（ v _ （ max ） ） ，動作電位幅度（ apa ）和舒張期除極化速度（ vdd ） ，起搏細胞放電頻率（ rpf ） ，而且能延長90動作電位時程（ apd _ （ 90 ） ） 。
  2. Vdd relies on the i / o permission mask to trap port access, and it essentially simulates the operation of hardware for the benefit of applications that were originally programmed to talk directly to hardware on a bare machine

    一個vdd依賴於一個i / o許可程序來限制埠訪問，並且它本來（是要）效仿硬體的操作，來幫助應用在一個裸機上同硬體直接對話的最初操作。
  3. A vdd relies on the i / o permission mask to trap port access, and it essentially simulates the operation of hardware for the benefit of applications that were originally programmed to talk directly to hardware on a bare machine

    一個vdd依賴於一個i / o許可程序來限制埠訪問，並且它本來（是要）效仿硬體的操作，來幫助應用在一個裸機上同硬體直接對話的最初操作。
  4. So we recommend that you connect any unused input terminal to vdd or vss, do not input any signals before power is turned on and ground your body, work assembly table and assembly equipment to protect against static electricity

    因此請勿將任何未用的輸入端接到vdd或vss ，不要在電源打開之前向模塊輸入任何信號，並將操作者的身體工作臺裝配臺接地，安裝設備需防止靜電。
  5. If rosc pin series a resister to vdd, or connect a capacitor to vss, the switching frequency can be adjusted

    切換頻率是由osc頻率決定，以rosc腳串聯電阻到vdd ，可調整切換頻率，電阻值減少，頻率增加。
  6. If rosc pin connect a resister to vdd, the switching frequency can be adjusted ; the value of resister decreases, the frequency will go higher

    切換頻率是由osc頻率決定，以rosc腳串聯電阻到vdd ，可調整切換頻率，電阻值減少，頻率會增加。
  7. The switching frequency is decided by osci frequency. if rosc pin series a resister to vdd, or connect a capacitor to vss, the switching frequency can be adjusted

    切換頻率是由osc頻率決定，以rosc腳串聯電阻到vdd ，或串聯電容到vss ，可調整切換頻率。
  8. St1689e has build - in switching frequency but can be decreased by connecting a cap. to osci. if rosc pin connect a resister to vdd, the switching frequency can be increased

    St1689已內建切換頻率，但接電容到osci可降低之，以rosc腳串聯電阻到vdd ，則切換頻率增加。
  9. St1688nd has build - in switching frequency but can be decreased by connecting a cap. to osci. if rosc pin connect a resister to vdd, the switching frequency can be increased

    St1688已內建切換頻率，但接電容到osci可降低之，以rosc腳串聯電阻到vdd ，則切換頻率增加。
  10. Fast charging with a high current supply should not be attempted on a deeply discharged battery ? the battery would draw excessive current, pull the vdd voltage down, and possibly cause a handset malfunction or shutdown due to an under - voltage lockout condition

    不要嘗試用大電流給一塊完全沒有電的電池快速充電，電池能夠吸取過量電流，拉低vdd的電壓，使手機處于欠壓條件下，可能造成手機故障或關機。
  11. Vdd irtual device drivers
