small amplitude wave
解釋
小振幅波-
It includes four criterions of locating fault point ? “ transient zero sequence current amplitude law ”, “ stable base wave zero sequence current phase law ”, “ stable seventh harmonic zero sequence current phase law ” and “ s injection law ”. pointing out how the law locate the fault point to minimal fault section by applying these criterions gradually. the law will not only make up the blemishes existing in current methods for single - phase fault location in small current grounding system, but also locate the fault point to minimal fault isolating unit on fault line
該方法通過將所包含的四個定位判據- 「暫態零序電流幅值法」 、 「穩態基波零序電流方向法」 、 「穩態7次諧波零序電流方向法」和「 s信號注入法」 -進行有選擇地遞進使用，不僅有效彌補了目前已有小電流接地系統單相接地故障選線的缺陷，更將故障定位在故障線路最小故障區段。 -
This article investigates the properties of solutions of the wave equations of kirchhoff type with nonlinear which arises from small amplitude vibrations of an elastic string and the properties of solutions of the beam equations
本文討論來自研究一根具有彈性的皮筋的小振幅振動的一類kirchhoff型方程的整體解和一類梁的橫振動方程的整體解的性質。 -
The direct solution for u ~ u and u ~ p form, the stagger solution for u ~ p form are compared in the convergency, stability and efficiency, from which it is concluded that the first solution used not widely before is characterized with weakly ill - conditioned stiffness and comparatively high efficiency. the finite element methods based on these three solving procedures are numerically implemented. the seabed soil under wave pressure with small amplitude can be viewed as elastic material
詳細比較廣義biot理論u u形式直接解法、 u p形式直接解法與交叉迭代法求解彈性、彈塑性問題的收斂性、穩定性與計算效率，認為以往較少應用的u u形式直接解法剛度陣病態性弱，求解效率高，更適合土工問題的數值模擬，小風浪作用下海床的動力響應特性可視為彈性的。
