For the determination of the chlorophyll in seawater, pigments of marine algae are extracted with 90 % acetone by the following three methods: 1 grinding in a homogenizer, 2 extracting by placing the samples in darkness for a period of time,and 3 using a sonic disintegrator.

本文讨论了用90％丙酮从海藻中提取叶绿素进行测定的三种提取方法(研磨法、浸泡提取法、超声波粉碎法)的最佳条件。并对三种提取方法的提取效率进行了比较。

The thesis introduces a kind of single-pulse-refection ultrasonic distance meter system module in detail based on Microcontroller.

本文介绍了一种基于单片机的脉冲反射式超声波测距模块。

An ultrasonic distance meter cancels out the effects of temperature and humidity variations by including a measuring unit and a reference unit.

提出了一种超声波测距仪来抵消的影响温度和湿度的变化，包括测量单元和参考资料。

This course is designed for those with no prior experience and covers Basic tool description and their proper uses including use of flexible shaft, Jewelers saw, ring clamp, pliers,drawplate,polishing tools and ultrasonic equipment.

这当然是专为那些没有以往的经验，包括基本工具描述和适当的用途，包括使用灵活的轴，珠宝商认为，环钳，老虎钳， drawplate ，抛光工具和超声波设备。

But there are vocal mimics too, like a palatable species of tiger moth that deters bats by parodying the ultrasonic clicks of a toxic moth the bats detest, or like the greater racket-tailed drongo of Sri Lanka, which mimics the calls of other birds to drum up a mixed-species flock in which the drongos can more safely and efficiently forage.

但是也有针对声音的欺骗术，比如有一种自身美味无比的灯蛾会很搞笑地模仿一种令蝙蝠厌恶的毒性飞蛾的超声波频率，藉此逃避被吞吃的命运；还有一种长着像火箭似的尾巴的伊斯兰卡燕卷尾会模仿其他鸟类的叫声，招揽来各式各样的鸟群，它们身处其中会更加安全而且掠夺食物也有效率得多。

The results indicated that the growth of cells was promoted under the ultrasonic irradiation by shortening the lag phase and increasing the volume of cell number and dry weight.

结果显示，细胞生长的促进下，超声波缩短滞后期数量，提高细胞数量，干重。
