不变

Existence, uniqueness and continuous dependence of C〓 solutions for an iterative functional equation related to invariant curves of functional differential equations with piecewise constant arguments are given under weaker conditions than that known results of C〓 solutions.

本章首先讨论了与逐段常时滞泛函微分方程不变曲线有关的一类迭代函数方程的连续解的存在唯一性和连续依赖性，不但弱化了已有结果的C〓光滑性的条件，还讨论了连续解的对称性，并根据对称性将一些结果推进到高维。

To enhance the accuracy of prediction of the futurology, it was necessary to capture the constant factors in the human society in order to clarify the positioning of a host of future variables in the time scale.

要提高「未来学」进行预测的准确度，关键是要掌握人类社会中「恒不变」的因子，才能厘清众多未来变数在时间尺度上的定位。

The use of fuzzy logic to optimize the efficiency of an induction motor is described in this paper.

该方法能在保证电机转速不变的情况下明显提高电机轻载时的效率。

The world famous Galapagos Islands should be visited at least once of you want to be surrounded by stunning untouched nature and tropical wildlife.

Under a Galilean transformation the equations of Newtonian dynamics are invariant , whereas those of electromagnetism are not.

根据伽利略变换的方程牛顿动力学是不变的，而电磁是不对的。

Garnier, however, has given her the Rich Dark Golden Brown (4.3) treatment, and to keep her true during her one-year contract, hair colouring expert Trevor Halls is on call to deal with her roots.

但这次卡尼尔给了她深金棕色(4.3)的护理，并要求她在一年合约期保持不变，染发专家特雷弗·霍斯被叫来处理她的发根。

The chemical composition of runing water remains constant whetIT it is in solid, liquid or gaseous state.

Here the key assumption is the existence of a translationallyinvariant measure on the local gauge group.

这里一个关键的假设是局域规范群上存在一个平移不变的测度。

The local gauge group is infinite dimensional and not lo-cally compact,hence the existence of an invariant measure deserves careful study.

After descibing the concepts, definitionsand operation approaches of quantum group and SLq(2) Lie algebra, the physicalmeaning of quantum group particles is explained in the present thesis. The gaugeinvariance in SLq(2) gauge field and its thermodynamics model is considered basedon the idea of q-deformation. The zero energy gap equation and q-deformed energygap equation are derived under the assumption of q-quantization and semi-classical q-quantization, then the zero-temperature energy gap A(0,q) and crititical temperature〓 can be calculated from the q-energy gap equation.

在介绍了量子群和SLq(2)李代数的基本概念，定义和运算方法后，文中进一步阐述了量子群粒子的物理意义；在q变形思想基础上，本文研究了SLq(2)规范场及其热力学模型中的规范不变性质，并在q量子化和半经典q量子化的假设下导出了零能隙方程和q变形能隙方程；然后从q能隙方程计算了与零温度能隙△(0，q)和临界温度〓。

The split between the two groups can hardly be papered over.
