拍

It is concluded that all of the tested bionic wings can generate lift force, however the flexible wing has best kinetic and aerodynamic performance among them, as well as flapping frequency and amplitude are the main factor of effecting on lift force generation.

实验结果表明，研制的翅型都能产生一定的升力，其中柔性翅具有较好的运动性能和气动性能，并且拍动频率和拍动幅度对升力有较大影响。

The obvious note of emphasis in each measure is the downbeat, the first beat of the bar.

很显然，每一小节的第一拍都是强拍。

This may be one reason why so many compositions begin with a partial bar – the first beat usually carries the accent and is too loud.

这也是很多曲子都是在不完整的小节开始的原因，小节的第一拍是强拍，音量太强。

This may be one reason why so many compositions begin with a partial bar – the first beat usually carries the accent and is too loud.

如果不太清楚，就照着这个规则做吧。这也是很多曲子都是在不完整的小节开始的原因，小节的第一拍是强拍，音量太强。

It will sound even better if you hold the tonika chord for the first beat in bar 12, and change to V7 on the second beat.

属七和弦的作用是一个回转和弦，如果你在第12小节的第一拍还保持着主和弦，到第二拍再转到属七和弦，那么效果听上去还会更好。

In mazurkas, for example, the emphasis may be on any beat of the bar; the melody may have its own accent on the first and third beats, and the accompaniment may have several voices, each with its own accents.

例如玛祖卡舞曲，重音可在小节里的任何一拍上；曲调也许在第一和第三拍上已经有它自己的加重音符号，而且伴奏也许已经有了几个声音，并且每个伴奏音也都有自己的加重音符号。

The V7 chord functions as a TURNAROUND chord. It will sound even better if you hold the tonika chord for the first beat in bar 12, and change to V7 on the second beat.

属七和弦的作用是一个回转和弦，如果你在第12小节的第一拍还保持着主和弦，到第二拍再转到属七和弦，那么效果听上去还会更好。

We first prove by experiment that a beat note injecting radiation can also induce a beat note from the slave laser with the same frequency.

我们首先利用实验证明若主要雷射为一拍频光束，注入后的从属雷射也会是相同的拍频光。

You should understand the time signature at the beginning of each composition. It looks like a fraction, consisting of a numerator and a denominator. The numerator indicates the number of beats per measure and the denominator indicates the note per beat.

你应该要认识一首曲子开头的节拍记号，它看起来像是一个分数，由分子与分母组成，分子表示每一段有几拍，而分母表示以哪个音符当作一拍。
