  1. Using the tip of the monopolar j - hook electrocautery, the proposed line of excision is circumferentially scored on the renal capsule around the tumour under real - time us guidance

    用單極j鉤電烙器頭端，切除的預定線為圍繞實時us監測腫瘤邊緣的腎包膜的壓痕。
  2. Hf - current in monopolar electrosurgery flows from an active electrode ( i. e. the instrument ) through the patient ' s body to a neutral electrode, patient plate, applied o his / her body

    在單極高頻外科手術中，高頻電流從活動電極（例如儀器本身）流經病人身體到達中性電極（附著在病人身體的病人板）
  3. Radiant characteristics of subnanosecond and monopolar pulse - excited aperture

    單極性亞納秒脈沖激勵口徑的輻射特性
  4. In this section, with time _ sharing method and the symmetry of sine wave, the look - up table needed to generate three - phase sine wave is reduced to one twelfth of the table before, and the optimization will have no any effect on precision, at the same time, the generation way of the monopolar spwm is improved

    在這一部分，還對產生二相正弦波的正弦表進行了優化，利用分時復用和正弦波的對稱性，把所需的正弦表減少為原來的1 / 12 ，並保持優化后的精度不變。同時改進了單極性spwm的產生方法。
  5. The aim of this study is to investigate theoretically the possibility for activation of small mammalian myelinated nerve fibers without activating larger ones when stimulating a nerve fiber bundle with a monopolar point electrode using biphasic pulses, which can reduce the electrochemical damage resulted from stimulation pulses to nerve fibers. a simulation system for studying the electrical properties of mammalian myelinated nerve fibers was built based on a simple infinite and homogeneous volume conductor model. by use of an asymmetric but charge - balanced stimulation waveform, the sensitivity of excitation and blocking threshold of nerve fibers to fiber diameter, electrode - fiber distance was calculated. the results show that selective activation of small mammalian myelinated fibers may be possible in a region at some distance from the electrode using biphasic pulses

    本研究的目的是要從理論上探討利用單電極雙向脈沖刺激實現哺乳動物神經纖維選擇性刺激， （即當刺激一束神經時，不興奮粗神經而興奮細神經）的可能性.雙向脈沖刺激可以降低刺激脈沖對神經纖維產生的電化學損傷.為研究哺乳動物有髓神經纖維的電特性，建立了一個基於簡單的無窮大、各向同性的容積導體模型的模擬系統.利用該模擬系統，採用「不對稱但電荷平衡」的雙向脈沖刺激，計算了神經纖維的興奮和阻斷閾值與纖維直徑、纖維-電極間距離的關系.結果表明：在距電極一定距離內採用該雙向脈沖刺激模式確實可以實現哺乳動物有髓神經纖維的選擇性興奮
