time coordinate

基本解釋

They were generated by singularities induced by the choice of the time coordinate, which are not present for physically admissible observables.
而數(shù)學(xué)上的描述同樣可解釋這一結(jié)論：因奇異點(diǎn)（奇異點(diǎn)，指計(jì)算步驟表現(xiàn)出函數(shù)的不連續(xù)或?qū)?shù)不存在特性的點(diǎn)）誘導(dǎo)産生的時(shí)間坐標(biāo)，不受觀(guān)測(cè)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(chǔ)上，通過(guò)大量實(shí)踐性實(shí)騐，騐証了時(shí)空坐標(biāo)轉(zhuǎn)換理論和場(chǎng)式時(shí)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(jù)相對(duì)論時(shí)空坐標(biāo)變換及光速不變?cè)?，推出了光在運(yùn)動(dòng)鏡麪上反射時(shí)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(shù)的實(shí)騐，但我們覺(jué)得,現(xiàn)在我們需要一些協(xié)調(diào)的戰(zhàn)略。

At that time t, the x coordinate must have a certain value.
在該時(shí)刻,x 坐標(biāo)一定是個(gè)確定的值

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.
