In the submicroscopic world, there is little prospect at present that curved spacetime will reveal itself. 目前在亚微观世界展现弯曲空时的希望不大。
But in the curved spacetime around a black hole, one member of the pair can be trapped inside the horizon, while the other gets stranded outside. 可是在黑洞附近的弯曲时空中，虚光子对的其中一颗可能会陷进视界之内，而另一颗却留在视界之外。
Einstein proposed that spacetime is curved by matter, and that free-falling objects are moving along locally straight paths in curved spacetime. 在牛顿物理学，然而，没有这样的加速，就可能发生，除非至少有一个物体正在运作的一支部队。
According to the General Theory of Relativity, the planets orbit the sun because they are taking the shortest path through the curved spacetime (recall the tennis ball). 根据广义相对论,行星之所以环绕太阳是因为它们沿弯曲时空的最短路线行走(回忆网球的例子)。
In a fluid moving nonuniformly, however, the phonons' velocity is altered and their wavelength can become stretched, just like photons in a curved spacetime. 然而，在流动不均匀的流体中，声子的速度会改变，而且它们的波长也会拉长，正如同弯曲空间中的光子一般。
Qualitative Physics Black holes require the general relativistic concept of a curved spacetime: their most striking properties rely on a distortion of the geometry of the space surrounding them. 黑洞需要弯曲时空广义相对论概念:他们最显著的特性依赖它们周围空间的几何学变形。
However, in 1974, Hawking applied quantum field theory to the curved spacetime around the event horizon and discovered that black holes can emit thermal radiation, known as Hawking radiation. 然而,在1974年,霍金将量子场理论运用到活动视界周围的弯曲时空上而发现黑洞能发出热辐射，就是熟知的霍金辐射。
According to Electrodynamics in curved spacetime, the interaction between gravitational waves (GW) and electromagnetic (EM) fields will produce perturbative electromagnetic fields. 根据弯曲时空中的电动力学,引力波和电磁场相互作用时将产生扰动电磁场。
The sinking of the trampoline represents how heavy objects curve spacetime. 蹦床的下陷描绘了大质量物体如何扭曲时空。
According to Einstein's equations, a sufficiently dense concentration of matter or energy will curve spacetime so extremely that it rends, forming a black hole. 根据爱因斯坦的方程式，该区域中物质与能量的密度要是够大，时空便会受到极大的弯曲，甚至分裂开来，形成黑洞。
In the submicroscopic world, there is little prospect at present that curved spacetime will reveal itself 目前在亚微观世界展现弯曲空时的希望不大。
A bullet describes a curved path in the air. 子弹在空中作曲线运动。
The spear curved through the air. 标枪在空中沿曲线运动。
The road curved suddenly to the left. 那条路突然向左转弯。
The road curved sharply to the right. 道路有个急转弯拐向右边。
A curved or barbed plant or animal part. 弯曲部分，有钩部分曲线形或长倒刺的动植物部分
