查询词典 mean

As another example, they specified that the mean synodic month was 29;31,50,8,20 days (four fractional sexagesimal positions), which was repeated by Hipparchus and Ptolemy sexagesimally, and is currently the mean synodic month of the Hebrew calendar, though restated as 29 days 12 hours 793 halakim (where 1 hour = 1080 halakim).

此处虽然如此表示，但很难相信古希腊人需要定义秒古希腊的时间周期，像是平朔望月定义得非常精确，因为他们不是观察单一的朔望月，而是以相距数百年的食来测量朔望月的平均长度。不过，发展出摆钟来保持平时（相对於日晷所显示的视时），使得秒成为可测量的时间单位。

Phoebe: Yeah, but did they have to shoot him down I mean, that was just mean.

菲比：没错，可他们有必要把它非射下来吗？我是说，这也太野蛮了。

Astronomy The fifth planet from the sun, the largest and most massive in the solar system, having a sidereal period of revolution about the sun of 11.86 years at a mean distance of 777 million kilometers (483 million miles), a mean diameter of approximately 138,000 kilometers (86,000 miles), and a mass approximately 318 times that of Earth.

The sixth planet from the sun and the second largest in the solar system, having a sidereal period of revolution about the sun of 29.5 years at a mean distance of about 1,425,000,000 kilometers (886,000,000 miles), a mean diameter of approximately 119,000 kilometers (74,000 miles), and a mass 95 times that of Earth.

土星：距太阳第六远的行星，是太阳系中第二大行星，绕日公转周期29.5年，公转平均半径约1，425，000，000公里（886，000，000英里），平均直径大约119，000公里（74，000英里），质量是地球的95倍

The fourth planet from the sun, having a sidereal period of revolution about the sun of 687 days at a mean distance of 227.8 million kilometers (141.6 million miles) and a mean diameter of approximately 6,726 kilometers (4,180 miles).

火星：距太阳第四近的行星。绕太阳公转周期为687天，距太阳平均距离为227.8百万公里141.6百万英里），平均周长大约为6，726公里(4，180英里）。

To signify or mean .I didn't mean to .

对不起，我弄伤了你；我不是故意的。

In the study of the stochastic chaos in simple pendulum, the random Melnikov process is derived and the mean-square criterion is used to determine the threshold amplitude of the bounded noise excitation for the onset of the chaos or random chaos in the system. For the coupled simple pendulum and harmonic oscillator, the Melnikov function is used to determine the condition for the onset of chaos in the case of Hamiltonian perturbations. In the case of non-Hamiltonian perturbation, the generalized random Melnikov process and mean-square criterion are used to determine the threshold amplitude of the bounded noise for the onset of random chaos.

在随机混沌研究中，应用随机Melnikov过程的均方准则研究了单摆在有界噪声激励下发生混沌或随机混沌时有界噪声激励的临界幅值；对于耦合的单摆-谐振子系统，先用Melnikov函数研究了在哈密顿扰动下发生混沌的必要条件；然后用推广的随机Melnikov过程方法研究了在非哈密顿扰动下发生随机混沌的必要条件；用最大Lyapunov指数及Poincaré截面方法结果与上述理论结果作了对比。

I mean, I didn't mean to snap the other night.

What do you think I mean? I mean when exactly do you take your socks off.

你认为是什么意思、我的意思是说什么时候脱掉你的袜子。

I mean, I mean white sparkling teeth.

我是说白得发亮的牙齿。
