触摸屏技术在我国的应用虽然只有十多年的时间，但是它已经成了继键盘、鼠标、手写板、语音输入后为普通百姓所易接受的计算机输入方式。

利用这种技术，用户只要用手指轻轻地触碰计算机显示屏上的图符或文字就能实现对主机操作，从而使人机交互更为直截了当。这种技术方便了用户，成为极富吸引力的全新多媒体交互设备。

弹簧进一步受压，只有在稍高的转速下运转才能使飞球的离心力与弹簧压力平衡。这说明负荷减小时稳定运转后，柴油机的转速比原来稍有升高。

同理，当负荷增加时，稳定运转后，柴油机的转速比原来稍有降低。具有刚性反馈的液压调速器，可以调速过程具有稳定的工作特性，但负荷改变后，柴油机转速发生变化，稳定调速率d不能为零。

Although the application of touch screen technology in our country is only more than ten years, it has become a computer input method that is easily accepted by ordinary people after keyboard, mouse, handwriting pad and voice input.

Using this technology, the user can operate the host computer as long as the finger gently touches the graph or text on the computer display screen, so that the human-computer interaction is more straightforward. This technology is convenient for users and becomes a very attractive new multimedia interactive device.

The spring is further compressed, and only by running at a slightly higher speed can the centrifugal force of the fly ball be balanced with the spring pressure. This shows that after stable operation in load reduction hours, the speed of the diesel engine is slightly higher than the original.

Similarly, when the load increases, after stable operation, the speed of the diesel engine is slightly lower than the original. The hydraulic governor with rigid feedback can have stable working characteristics during the speed regulation process, but the diesel engine speed changes after the load changes, and the stable speed d can not be zero.
