不变

Because this extra force is nearly always there (it is a component of the gravitational force on us), we don't notice it.

因为这个额外的力几乎一直保持不变（它是我们所受重力的一个分量），所以我们感觉不到它的存在。

In the other words, the influences of the winding's current cannot be think about by simply add these influence elements of these windings, the inductance of every winding becomes a complex equation which connected with the currents of all the windings and the permanent magnetic magnetic-force.

永磁磁动势的大小不变，但是转子位置改变时，对各相绕组的轴线的磁通路来说，永磁磁动势的作用便不一样，因此永磁磁动势的影响可以用电感与转角有关来描述。

The law of conservation and transformation of energy states that energy is indestructible and the total amount of energy in the universe is constant.

参考译文：能量守恒和转换定律说明：能量是不灭的，宇宙间能量的总量和是不变的。

If a body is in the absence of any external torque, the angular momentum of the body is a constant. This is known as law of conservation of angular momentum.

如果物体所受的合外力矩等于零，或者不受外力矩的作用，物体的角动量保持不变，这个结论叫做角动量守恒定律。

If the rotating rod is not magnetic, the force is constant (provided you can keep their positions steady).

如果旋转着的那根不是磁铁，那么磁力的大小会保持不变（前提是你可以保持它们的位置不要移动）。

The price is constant in several years in the underdeveloped countries.

在不发达国家，物价会连续几年保持不变。

The price remains constant for several years in developing countries.

在不发达国家，物价会连续几年保持不变。

The price is constant in several years in theundeveloped countries.

在不发达国家，物价会连续几年保持不变。

It was shown that when the production function was constant return to scale, the model became a A-K model; when the production function was increasing return to scale, the equilibrium point was unstable; when the production function was decreasing return to scale, the equilibrium point was a saddle.

结果发现：生产函数为规模收益不变时，模型简化为A-K模型；生产函数为规模收益递增时，均衡点为不稳定结点；生产函数为规模收益递减时，均衡点为鞍点稳定。关键词：数理经济学；经济增长；政府支出；生产效应
