- Smaller than a distance of about 10-35 meter, known as the Planck length, neither relativity nor standard quantum theory can predict what the particle will do. 可是到了比10-35公尺（即所謂的普朗克長(cháng)度）還小時(shí)，不管是相對論還是標準的量子理論，就都沒(méi)辦法預測粒子會(huì )有什麼行為了。
- Such a density would have been enough to create black holes a mere 10-35 meter across (a dimension known as the Planck length) with a mass of 10-8 kilogram (the Planck mass). 這樣的密度已足以創(chuàng )造出直徑僅10-35公尺（所謂的普朗克長(cháng)度）且質(zhì)量為10-8公斤（普朗克質(zhì)量）的黑洞。
- Alternatively, wormholes might naturally come into existence on tiny scales, the so-called Planck length, about 20 factors of 10 as small as an atomic nucleus. 另一種可能性則是，蠹孔可能在普朗克長(cháng)度（約10-33公分）這種極微的尺度下自然存在，這可是只有原子核的1/1020那麼小。
- Physicists have long assumed that the size of these cells is the Planck length( lP) of10-35 meter, which is the distance at which both quantum fluctuations and gravitational effects are important. 物理學(xué)家一向假定這些泡沫單元的大小為普朗克長(cháng)度（P,10-35公尺）在此距離範圍內，量子漲落與重力效應都很重要。
- It is shown that under the quantum conformal fluctuation the expectation values of the proper time and the proper length in any space-time are bounded at Planck time t_p and Planck Length l_prespectively. 在這種量子共形起伏下;任何時(shí)空的本征時(shí)間和本征長(cháng)度的最小極限分別為普朗克時(shí)間 t;和普朗克長(cháng)度1_p.
- According to the simplest computations based on this theory, these energies should add up to a tremendous density of about 1094 grams per cubic centimeter, or one Planck mass per cubic Planck length. 依據量子場(chǎng)論所做的概略估算發(fā)現，這些能量的總和相當巨大，密度大約為每立方公分1094克，或每立方普朗克長(cháng)度含一單位普朗克質(zhì)量。
- Gravition: from the hubble length to the planck length 引力作用:從哈勃長(cháng)度到普朗克長(cháng)度

- This river is ten times the length of that River. 這條河的長(cháng)度是那條河的十倍。
- She paced out the length of the room. 她用步子測量了房間的長(cháng)度。
- He fished a length of string out of his pocket. 他從口袋里掏出一條繩子。
- You spend a ridiculous length of time in the bath. 你洗澡用那麼長(cháng)時(shí)間，真不像話(huà)。
- Promotion will go by length of service. 晉升以服務(wù)年限為準。
- He measured the length of the room. 他量了房間的長(cháng)度。
- She paced out the length of the garden. 她用步子量出了花園的長(cháng)度。
- My estimate of the length of the room was 10 feet. 我估計房間的長(cháng)度為10 英尺。
- The room is15 feet in length and10 feet in breadth. 這房間長(cháng)15英尺，寬10英尺。
- She sprinted the length of the road. 她全速跑完了那條路的全長(cháng)。
