平直时空

Example Sentences:

	1.	Abstract : the conformal flat space - time solutions in electromagnetic and scalar theory are shown , and the indefiniteness of the plane - symmetric solutions and the method for defining a noncontinuous field by the intersection of multi - solutions are demonstrated 文摘:给出电磁场和标量场在共形平直时空中的解,发现了平面对称解的不确定性及由多重解的交集来定义一个非连续场的方法
	2.	The one - loop vacuum polarization is calculated for untwisted and twisted scalar fields in a flat space - time with the topology s1 r3 . the effect of vacuum polarization upon photon propagation is considered . it is found that for the untwisted scalar field some photon modes acquire a positive topological mass , thus travelling at a subluminal speed ; but for the twisted scalar field some photon modes get an imaginary topological mass and travel at a superluminal speed 本文中我们首先计算了在拓扑结构为s ~ 1 r ~ 3的非minkowski时空中扭曲标量场和非扭曲标量场的真空极化，然后考虑了真空极化对光子传播的影响，我们发现除了光子的极化方向和传播方向都垂直于紧致化方向的情形之外，非扭曲标量场的真空极化使所有其他的光子模式都获得实的拓扑质量从而导致这些光子以亚光速传播；但是，扭曲标量场的真空极化使光子获得虚的拓扑质量以致他们以超光速传播。
	3.	The equilibrium thermal radiation in a flat space - time or a curved space - time behaves like planck black spectrum represented with coordinate quantities . we regard the fact that the radiation from a thermal equilibrium system shows planck black spectrum as a basic physics law , from which it is demonstrated that the transitivity of clock rate synchronization is equivalent to the zeroth law of thermodynamics . the condition of clock rate synchronization is weaker than that constructing simultaneity surfaces . in the space - time satisfying the condition of clock rate synchronization , the zeroth law of thermodynamics is valid . on the other hand , in the space - time where the zeroth law is valid , one can define an identical clock rate 平直或弯曲时空中的平衡热辐射，表现出用坐标量表示的普朗克黑体谱.把热平衡系统的辐射具有普朗克黑体谱作为一条基本的物理规律，以此为基础，论证钟速同步的传递性等价于热力学第零定律.钟速同步的条件比建立同时面的条件要弱.满足这一条件的时空，热力学第零定律在其中成立.第零定律成立的时空，一定可以定义统一的钟速
