  1. Then, an implicit expression for electron density and a closed form of threshold voltage are presented fully comprising quantum mechanical ( qm ) effects

    給出了電子密度的隱式表達式和閾電壓的顯式表達式，它們都充分考慮了量子力學效應。
  2. The simplified gaussian approximation can be obtained, which has almost the same in accuracy but much less calculations than improved gaussian approximation method. the single traffic cdma system in nakagami fading channel with rake receiver is investigated extensively. a closed form ber expression is obtained with arbitrary chip waveforms

    由於在用戶小時其誤差大，改進高斯法可以提高精度，但需要更多的計算時間，少用戶時直擴系統的工程計演算法能夠獲得與改進高斯法相似的精度，但需要的運算量大為減少。
  3. Comparing the fitted expression with the established theory expression of the angular velocity, the equivalent viscous damping coefficient is gained. the closed form algorithm of the state space method is employed to solve the system dynamic equation with time - varying coefficients. the dynamic problem of a linkage mechanism with four joints is taken as example to show that the presented models and methods are correct and practicable

    引入求解線性微分方程的狀態空間法，並對其求解時變系統運動微分方程的具體步驟進行了推導；在此基礎上將實測獲得的運動副等效粘性阻尼系數代入系統動力學方程，求解后獲得了考慮運動副阻尼的平面彈性四連桿機構的模擬結果；結果表明運動副的阻尼在一定程度上對振動具有抑制作用。
  4. The total normal stresses arc then modified by satisfying the rigorous equilibrium conditions for the whole sliding body, resulting in an closed form expression for the required magnitude of anchoring force
