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。 -
Technically, the damping factor is the specified load impedance ( in use, that ' d be the speaker system ) divided by the amplifier ' s output impedance
技術上，阻尼因子就是指定的負載阻抗（實踐中，也就是揚聲器系統）除以放大器的輸出阻抗。 -
Technically, the damping factor is the specified load impedance ( in use, that ' d be the speaker system ) divided by the amplifier ' s [ i ] output impedance [ / i ]
技術上，阻尼因子就是指定的負載阻抗（實踐中，也就是揚聲器系統）除以放大器的輸出阻抗。 -
We can also see that because damping factor is a ratio that requires the load impedance to compute, it must be stated against some known impedance to be meaningful
我們還可以看到因為阻尼因子是一個比率值，而且需要負載阻抗已知才能夠進行計算，所以阻尼因子必須和某一已知的阻抗同時具明才有意義。 -
Calibrating the gravity model consists of evaluating the parameters of the impedance function ( or the values in the friction factor table ) so that the gravity model reproduces, as closely as possible, the base year productions and / or attractions and the base year trip length distribution
校準重力模型就是計算阻抗函數參數（或者摩阻系數表中的值） ，使其盡可能吻合基年產生和吸引，以及基年的出行距離分佈。 -
As an alternative to impedance functions, one can use a friction factor lookup table ( essentially a discrete impedance function ) that relates the impedance between zones to the attractiveness between zones
對于阻抗函數的選擇，你可以採用摩擦系數查詢表（本質上也是一個離散阻抗函數）來描述小區之間的阻抗。 -
The effect on the generator excitation magnetic field is different when the capacity and power factor of load are different, and the effect on the internal impedance voltage drop is different, too
而不同容量的負載，以及負載的不同功率因數，對同步發電機勵磁磁場的作用是不同的，對同步發電機的內部阻抗壓降的作用也是不一樣的。 -
The pile group and the surrounding soil are discretized into horizontal layers, which meets a plane strain assumption. by means of that the single pile dynamic impedance is developed with a transfer matrix method, the pile - to - pile dynamic interaction factor is derived. then, the dynamic impedances of rigidly - capped pile groups with due consideration to pile - soil - pile interaction for vertical oscillations are produced
本論文充分考慮土的成層性和沿深度有變化的特性，將土層沿深度離散形成一系列均質的土層，各土層視為滿足平面應變假定，應用傳遞矩陣法推導出單樁在成層地基中的動力阻抗；並據此研究了在成層地基中的樁-樁動力相互作用因子，然後推導了群樁剛性承臺豎向動力阻抗。
