不变

Like the ancien régime in France, which believed that feudal property could be maintained by conservative force of law despite the modernization of society, the owners of bourgeois culture expect their law of property to provide a magic bulwark against the forces they have themselves released.

就像法国的旧政权曾经相信，保守的法律力量能够在社会的现代化过程中保留（维持？——是有新的同时保留旧的？还是仅仅维持旧的不变？）封建所有制一样，资产阶级文化的所有者也期望，他们的所有权法律能够在他们自己释放出的冲击力之前筑起一道防护堤。

The first process is to optimize the geometric parameters of the press, on the assumption that the servomotor rotates at a constant angular velocity equal to that of the constant velocity motor. The second process is to optimize the displacement trajectory of the servomotor based on the results of the first process while keeping the geometric parameter unchangeable.

然后，建立了混合驱动压力机的优化设计模型，并将优化分为两步：第一步，假定伺服电机角速度与常规电机相同的条件下，优化设计出压力机的尺寸参数；第二步，在第一步优化结果的基础上，使机构的尺寸参数不变，优化设计伺服输入运动规律。

In one direction there is a constant gravitational force, in the other very many irregular blows from the molecules.

在一个方向上有不变的重力在作用，在另一个方向上则是分子的大量不规则的碰撞。

The sum of the two quantities remains unchanged, and is called a constant of the motion.

这两个量的和保持不变，称为运动恒量。

The stability of copper reduced because of the formation of copper oxide under alkaline condition, while the stability of copper kept the same because of the constant chemical structure under near neutral condition.

在去离子水中， Cu-KEtX的化学结构则没有明显的改变，故对Cu的稳定性亦不变。

We know that there is this constant media pressure in Italy.

我们知道，在意大利，媒体的压力是持久不变的。

Tt is important to keep the temperature and pressure constant in an experiment.

在实验中，让温度和压力保持不变是很重要的。adj.2。不断的；继续的；恒久的

How do you demonstrate that the pressure remains constant?

你怎样证明压力保持不变？

At constant temperature, the pressure of a gas is inversely proportional to its volume.

温度不变，则气体的压力和其体积成反比。

Now let us assume that the price of good 2 and the agent's income remain constant but the price of good 1 decreases.

现在让我们假设2的价格和良好的代理人的收入保持不变，但良好的价格下降1。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
