time coordinate

基本解释

They were generated by singularities induced by the choice of the time coordinate, which are not present for physically admissible observables.
而数学上的描述同样可解释这一结论：因奇异点（奇异点，指计算步骤表现出函数的不连续或导数不存在特性的点）诱导产生的时间坐标，不受观测者变换的影响。
In a word, on the basis of theoretical research, this paper verifies the space-time coordinate transformation theory and field-mode time-grating theory through doing experiments in a large amount.
总之，本文在理论研究的基础上，通过大量实践性实验，验证了时空坐标转换理论和场式时栅理论。
According to space time coordinate transformation and permance principle of light velocity in the theory of relativity, the rule of light reflection from the moving mirror is proposed in this paper.
根据相对论时空坐标变换及光速不变原理，推出了光在运动镜面上反射时遵从的规律。

MIT has undertaken a variety of experiments in Educational technology. But we really feel at this Point of time we need some sort of coordinate strategy.

Which is just fine, as long as no one is trying to coordinate time east to west (or even west to east).

Even more important, however, is to discuss how you will pay for college ahead of time with a financial planning or tax professional so that you can coordinate ahead of time how to best pay for college using the income and assets that you have, and still be eligible to claim the full amount of college tax credits that you are eligible for.
