Compliance steering operates only at certain lateral acceleration of vehicle. At low lateral acceleration, it doesn't work, the vehicle's performance is like the front wheel steering vehicle's; at high lateral acceleration, it can prevent the vehicle from losing its stability, which is caused by excess steering angle of the rear wheel, by the limiting position function of rubber mounting.

随动转向效应仅在特定的侧向加速度段起作用，在小侧向加速度段，随动转向不起作用，车辆性能与普通前轮转向车一样；而在很高侧向加速度段，它可以通过橡胶悬置的限位作用来确保车辆不致于因后轮转角过大而失稳。

Under such a solidification condition that the growth rate is low and the temperature gradient ahead of the solidi fication front is steep, a large amount of α-Al nuclei can be produced by peritectic reaction, during which only metastable Al〓Zr particles or very fine equilibrium Al〓Zr particles rather than larger equilibrium Al〓Zr partiles are involved.

在低的生长速度和高的界面前沿温度梯度条件下，结晶前沿Al〓Zr粒子与液态铝发生包晶反应（只涉及亚稳Al〓Zr或尺寸极小的平衡Al〓Zr，而不涉及尺寸较大的平衡Al〓Zr）产生大量α晶胚，α晶胚呈球面生长，最终形成等轴非枝晶形态。

This results in a higher possibility for the components to enter the unstable demixing gap after the rapid phase separation of the system has taken place.Therefore,a bicontinuous structure is easily formed for CA membrane. For the systems of ScCO_2/toluene/PSt and ScCO_2/solvent/PVB,the increase of temperature or decrease of pressure leads to the binodal curves shifting toward the polymer/solvent axes,and thus results in the decrease of miscibility gap.The membrane toplayers of ScCO_2/solvent/PVB systems are dominated by the equilibrium thermodynamics,while the formation of membranes sublayers is the result of the combination of the equilibrium thermodynamics and membrane formation kinetics.

以下时由双节线、旋节线之间构成的亚稳互溶分相区很窄，使得该体系在快速分相后其组成变化进入旋节线内不稳分相区的可能性极高，从而易导致CA膜形成双连续结构；温度升高或压力减小均可导致ScCO_2/甲苯/PSt与ScCO_2/溶剂/PVB两种铸膜体系的双节线向聚合物/溶剂轴一侧靠近，均相区减小；ScCO_2/溶剂/PVB体系的膜表面结构形成主要受平衡热力学过程的控制，而膜的截面结构是其平衡热力学与扩散动力学共同作用的结果。

Only with such characteristics, the movement equations can be expressed as matrices, and the idea of transforming the movement equations to the simplest form through a nonlinear transformation can be realized;(2) The form of Zi =Yi + YTH2i Y + Y7H3i Y(2)+ Y(2)T H4i Y(2)+ YTH5i Y(3) is adhibited in the nonlinear transformation, so that the multivalued problem caused by the nonlinear transformation is avoided, and the higher order transformation can be taken next;(3) The fourth order nonlinear transformation matrices H21,H31,H41 and H51 are derived, by which the original movement equations of electric power system is transformed to Jodan form in Z space;(4) By use of the fourth order nonlinear transformation, the approximate expression of the stability boundary is obtained, in Z space it is Z1= 0,in Y space it is Y1 + YTH21 Y + YTH31 Y(2)-i- Y(2) TH41 Y(2)+YTH51 Y(3)= 0;(5) The criterion used in this paper to judge whether the system critical unstable is simple and quick;(6) The method used in this paper is a direct method, and no need to construct an energy function.

正是由 于电力系统的运动方程具有这样的特性，才能写成矩阵的形式，通过非线性变换将电力系统的运动方程变换为最简单的线性形式的思想才能得以实现；（2）将通常运用于电力系统暂态稳定性分析的Normal Form变换的形式由 Yi＝ Zi＋ ZTh2riZ变形为 Zi＝ Yi＋YTH2iY＋YTH3iY（2）＋Y（2）TH4iY（2）＋YTH5iY（3），从而使得在对持续故障轨线实施同样的非线性变换以确定临界切除时间时，避免了非线性变换带来的多值性的问题，而只有在没有多值性问题的困扰下，才能采用较高阶的变换：（3）推导出了将原始电力系统系统的运动方程变换到Z空间的约当形式的非线性变换矩阵H21、H31、H41、HS1：（4）在运用四阶了「线性变换的情况下，给出了受扰动后系统的稳定边界的近似的解析表达，在Z空间为Z1=0，在y空间为： Y1+YTH21Y+YTH31Y(2)+Y(2)TH41Y(2)+YTH51Y(3)=0 （5）确定临界失稳的判据简单、快捷：对于一个复杂的电力系统，其稳定边界是相当复杂的一个高维曲面，即便是已知系统稳定边界的解析表达，要求出系统持续故障轨线何时与这一高维曲面相交，在数学上几乎是不可能实现的。

It also becomes more difficult to model and simulate power grid. Traditional"Quasi-stationary"phase models can't be used for studying electromagnetic transient phenomena; on the other hand, the EMTP models can be used to analyze the electromagnetic transient accurately, but for the limitation of the step size, it can't be used to simulate the large network with a high speed.

这对电力系统的建模和仿真提出了更高的要求，传统的机电暂态模型由于建立在&准稳态&假设基础之上，因此不能用来仿真变化迅速的电磁暂态过程；而电磁暂态模型，虽然能准确反映电磁暂态过程，但由于仿真步长很小，仿真速度受到限制，不适合用来仿真大型电力系统。
