  3. Compared with the similar research results, the weighted control ic here has the following characteristics : ( 1 ) the circuit structure is simpler ; ( 2 ) the chip ' s fabrication is compatible with standard cmos process ; ( 3 ) n - mosfets with high w / l ratio and short channels are used for weighting and output to reduce the insertion loss ; ( 4 ) the weighting factor varies in a relatively wide range with the controlling signals ; ( 5 ) input and output impedance approach 50 in low frequency ( e. g. 50mhz ), while in higher frequency they slightly deviate from 50, hence the energy reflection lower than 0. 1 ; ( 6 ) it completes the functions of sampling, weighting, controlling and summing of high frequency analog signals

    它的加權控制電路與已報道的相關電路相比具有如下特點：電路結構簡單；製造工藝與普通cmos工藝兼容：短溝道，高寬長比的nmos晶體管具有低的通導電阻，將其作為加權、輸出器件可降低由電路引起的插入損耗；改變加權信號，可實現權值在較大范圍內的連續變化；輸入、輸出阻抗在低頻（如50mhz ）下接近50 ，而在高頻下略有偏離50 ，但反射系數均低於0 . 1 ；實現了對高頻信號的取樣、加權、控制、疊加功能的迭加。
  4. The second part is a detector which is used to detect the distribution of voltage on the patient ' s brain surface from all different directions. the third is a mixed signal processor ( c8051f020 ) which is used to control the other parts of the system and display some necessary information and convert the voltage signals into digital signals, as well as transmit the acquired data to the computer. the fourth is computer with eit software which is used to analyze and process the received data and construct a picture for the brain edema and haematoma on screen

    32通道電阻抗斷層成像系統由4個部分組成：第一部分是正弦波恆流源，用來產生注入大腦的激勵電流；第二部分是電位信號的提取與轉換，用來提取當激勵電流注入時，在大腦表面形成的電位分佈信號；第三部分是數據採集與控制系統，用來控制激勵電流的頻率，注入方向，注入強度，控制採集大腦表面的電位分佈信號，並且將這些採集的電位分佈數據傳到pc機；第四部分是計算機eit成像軟體，用來接收下位機的電位分佈數據，並且對這些數據進行分析計算，重建電阻抗圖像。
  5. Since there are more low - frequency elements in the engine noise, and simply barring cannot guarantee satisfactory depression, a composite impedance structure should be applied in muffling passages so as to control the propagation of low - frequency noises by means of the muffling characteristic of the resistance structure

    由於發動機噪聲中低頻成分更為豐富，單純阻擋不能達到滿意效果，因此消聲通道應選用阻抗復合結構，藉助抗性結構的消聲特性來控制低頻噪聲的傳播。
