Around 1650,Otto von Guericke built a crude friction generator- a sulphur ball that rotated at high speed on a shaft.
潮汐流发生器:类似于风力涡轮机,但这些涡轮机位于水下并利用水流的动能驱动涡轮机。
Tidal stream generator: Similar to wind turbines, but these turbines sit underwater and use the kinetic energy of water flow to drive the turbines.
游泳池配有来自美国的气动波发生器,是世界上最大的,75米长,30宽,3深。
The pool, equipped with pneumatic wave generators sourced from the USA, is the world's largest, 75 meters long, 30 wide, and three deep.
Shannon博士将在演讲中介绍当今光纤激光产生器的演变及其强大的先进功能。
In his presentation,Dr. Shannon will discuss the evolution of today's fiber laser markers and highlight their powerful advanced capabilities.
在那之前,他领导了公司多个产品管理团队,包括2009年发布的S9™气流发生器。
Prior to that appointment, he led several product management teams within the company,including the launch of the S9™ flow generator platform in 2009.
这些包括噪声抑制绝缘墙壁和白噪声发生器,使低水平的声音来帮助面具和外界噪声淹没了。
These include noise dampening insulation for walls andwhite noise generators which make a low level sound to help mask and drown out outside noise.
学生还参与使用海洋测试设施的实际工作(拖曳水箱,配备多瓣波发生器的波浪罐等)…[-].
Students are also involved in practical work using the ocean test facilities(towing tank,wave tank equipped with a multi-flap wave generator etc.)…[-].
所以在使用发生器时不仅环境需要保证通风良好,而且采用稳压电源供电显得尤为重要。
Therefore, in the use of generators not only the environment needs to ensure good ventilation, and the use of regulated power supply appears particularly important.
Friction electrostatic generators: cylinder(left) and disc(right) designs. According to Bird, the disc design has a greater power output, while the simpler construction of the cylinder makes it easier to operate.
