不变的

In retiming registers are added at some points in a circuit and removed from others in such a way that the functional behavior of the circuit as a whole is preserved. By retimng we can optimize the speed, area or power of the circuit.

重定时在保证功能不变的前提下，通过移动时序元件的位置和改变时序元件的个数来优化同步时序电路的速度、面积和功耗。

The improvements in the IAGA contained adding strengthen operator, improving evaluation index of premature, etc. Multi-phase homing project, making use of the flight properties of parafoil system in gliding and turning, was simple in control and facile in practice. Based on Frenet frame, the linear time-variable error equations of parafoil system were built.

基于Frenet坐标系推导和建立了翼伞系统线性时不变的误差方程，并运用&投影点&的思想来获得Frenet坐标系下偏差量的解析近似表达式，从而设计了用于翼伞系统航迹跟踪的传统PD控制器和增益调节型模糊PD控制器。

Dwarp control:this motion delivers warp to the weaving area at the required rate and at a suitable constant tension by unwinding it from a flanged tube known as the weaver's beam.

经纱控制：此运动将经纱从一个被称为织轴的带边的筒管上退绕下来，按所需的量和不变的张力将经纱送入织造区。

The exact solution for unlimited long strip plane membrane is obtained by analytical method,and discussed with the approximate solution by energy method.

在垂直于板的载荷作用下，平衡方程为σx2wx2+σy2wy2+2τ2wxy=qh[2]。这个方程虽然是在变形后建立的，但载荷的大小和方向是不变的。

The hierarchy of medical occupations is in many ways a caste system; its strata remain intact and the practitioners in them have very little vertical mobility.

医疗职位的层级制度在很多方面都是一个层级体系，他的层级是保持不变的而且其中的从业者几乎没有垂直机动性。

A lolita with one blouse, two skirts, two headdresses, and two pairs of socks which all match has more options than a lolita with two complete, but entirely different, outfits.

但是一个&虽然只有一件衬衫、两条裙子、两个头饰和两双袜子，但是搭配起来很合适&的洛丽塔，和一个&虽然有两套风格不同，但是却是成形不变的套装&的洛丽塔相比较，前者有更多的选择。

It allowed them to observe the still, fixed colours of the stars; to watch from the outside as lightning forked through a weather front; to measure the spiders' webs of cities against the immense blue of ocean and the matt black of far space.
