In order to compensate the hypothesis in EKC model that environment does not influence economy, and the defect that the variables in EKC model are difficult to estimate, the article studied their dynamic relation between environmental pollution and economic routh with VAR model.

为弥补EKC模型中环境不影响经济的假设与变量难以量化的不足，运用VAR模型研究二者的动态关系。

But what Jonathan Routh preferred to do was to dress up as a tree, wait at a bus stop and enquire which bus would take him to Sherwood Forest.

然而乔纳森·罗斯偏偏喜欢打扮成一棵树，等在公交车站，看哪路巴士愿意载他去舍伍德森林。

Based on the theory and experiments, the paper builds up the simplified mathematical model of the servo control system, deduces the system control rigidity expression, and points out the method to improve control rigidity. According to Routh stability criterion, the analytic stability condition is solved, which shows the conflict between the stability and control rigidity and that gyroscope is the key factor of the conflict.

论文结合理论和试验建立了光电稳定伺服控制系统的简化数学模型，推导出系统控制刚度表达式，指出提高控制刚度的方法；利用劳斯判据求解出系统稳定的解析条件式，描述了稳定性与控制刚度之间的矛盾，并指出陀螺是矛盾关键。

According to the Routh criterion, the linear interval mathematical model system stability's necessary and sufficient conditions are the first row numbers and are all positive numbers; they equal to its lower bound over zero.

根据Routh判据，区间数学模型的线性系统稳定性的充要条件是第一列全部为正数，等价于其下界大于零。

Dynamical property of the system model with two populations is studied based on Lyapunov stability theorem and Routh-Hurwitz criterion.

运用Routh-Hurwitz判据研究了两种群系统模型的动力学性质。

The feedback controls, including linear, speed, doubly-periodic function, hyperbolic function and trigonometric function are used to suppress chaos to one of the three unstable equilibrium. The Routh-Hurwtiz theorem is applied to derive the conditions of stability of the controlled system.

利用反馈控制方法，包括线性、速度、双周期函数、双曲函数和三角函数反馈控制方法将系统的混沌运动控制到稳定态，根据Routh-Huriwtz准则获得了系统达到控制目标时反馈系数所满足的条件。

In this thesis, we analyze the zeroth order term of eigenpolynomial of linearized matrix, and a necessary condition for diffusion-driven instability of n-species of a reaction-diffusion system is attained by using the Routh-Hurwitz criterion.

本文我们讨论含有n(。23)个物种的反应系统，对系统在无扩散时稳定的平衡态解附近线性化，通过分析线性化矩阵特征多项式的零次项，根据Routh一Hurwitz准则，得到了零次项使系统产生扩散驱动不稳定性的必要条件。

After the show's demise Mr Routh continued to lead a prankish and other-worldly life, shifting from England to Italy and Jamaica as the sun shone, running through various affairs, and bartering bright primitive paintings to settle his restaurant bills.

偷窥》节目停播之后，罗斯仍然引领着恶作剧和其他另类生活方式，跟随太阳的步伐在英国，意大利和牙买加之间游走，纵情声色，韵事无数，用自己的原生态简笔画冲抵餐厅账单。

偷窥》节目停播之后，罗斯仍然引领着恶作剧和其他另类生活方式，追逐阳光离开英国前往意大利和牙买加，到处插科打诨（实在弄不明白这两处是什么意思），用自己的原生态简笔画冲抵餐厅账单。

By rescaling the system,we obtain the Lorenz-Stenflo system with slow variation of the flow rotation. Based on Routh-Hurwitz criteria,the stabilities of the equilibria are analyzed and the bifurcation sets are sought to divide the parameter plane into different regions,corresponding to different types of the solutions.

通过对系统的重新标度，得到了气流旋转缓慢变化时的Lorenz-Stenflo系统；基于Routh-Hurwitz准则，分析了平衡点的稳定性问题，得到了参数平面上的分岔集，这些分岔集将参数平面划分为不同的区域，在各个不同的区域对应于系统不同的解。

It's not quite as simple as that.

并没有那么容易。
