Introduction The bearing capacity of pile foundation varies because of the difference of pile physical dimension, constraint condition of pile top, pile material strength and the characteristics of foundation soil.
Those of nonlinearity include concrete material nonlinearity, geometric nonlinearity of large displacement between pile and pile side soil, the nonlinear behavior of the soil around pile boundary slippage from pile.

Introduction "Proton sponges" [1, 2], the bi-center nitrogen bases, exhibit a strong basicity and demonstrate an unusual reactivity that organic chemists are exploring for the synthesis of effective new catalysts [3], new photochromic materials and other types of potentially useful compounds [4].

Considering machining efficiency and accuracy, machining gap should be the corresponding gap value when the machining speed reaches its maximum. 1 Introduction Electrochemical machining (ECM) is a kind of material removing machining process, which is based on the principle of electrochemical dissolution of anodic metal in electrolyte.
The typical experimental conditions are as follows: workpiece material is 0Cr18Ni9, concentration of 3NaNO solution is 40g/L, and machining voltage is 5V, so  =3.67e-5 3 cm /(A s) , =0.037 -1 (Ω cm) , RU ≈5V, and =0.4[9].
