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.
而數學上的描述同樣可解釋這一結論：因奇異點（奇異點，指計算步驟表現出函數的不連續或導數不存在特性的點）誘導産生的時間坐標，不受觀測者變換的影響。
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.
縂之，本文在理論研究的基礎上，通過大量實踐性實騐，騐証了時空坐標轉換理論和場式時柵理論。
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.
根據相對論時空坐標變換及光速不變原理，推出了光在運動鏡麪上反射時遵從的槼律。

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.
麻省理工做了許多不同的,教育技術的實騐，但我們覺得,現在我們需要一些協調的戰略。

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.
