If device i did not generate the interrupt it will propagate the acknowledge signal to device ii . 如果设备不产生中断，则把应答信号传输到设备。
Plastic foams are perhaps only 1/5 as effective as a good dewar from a heat transfer standpoint . 从热传输的观点来看，塑料泡沫的效率只及好的杜瓦瓶的五分之一。
If the temperature gradient becomes too large, then convection will take over the bulk of the energy transport . 如果温度梯变得太大，那么对流将承担能量传输的大部分。
Our physical picture of guided light propagation is that of light traveling in zigzag fashion through the film . 导波光的传播的物理图象就是光按Z字形方式通过薄膜传输。
A laser beam travelling through an enclosed tube can carry as much information as 80 million tv channels ! 在一个封闭管道中传输的激光束能传送多达8000万个电视频道的信息。
Physical units transmit information to and from the microcomputer via appropriate interface logic . 各种实体设备能够通过适当的接口逻辑电路对计算机传输（输入或输出）信息。
Television systems, which transmit 30 picture frames per second, must operate on a broad electromagnetic spectrum . 每秒传输30幅图象画面的电视系统，它必须工作于宽带电磁波谱。
The substitution of evacuated powders for high vacuum alone will usually improve the insulation by reducing the radiant heat transfer . 只需用抽空气体的粉末而不用单纯的高真空，一般便可减少辐射热传输，从而提高绝缘度。
The transmitted information is coded into the amplitude of the pulses so that each predetermined value of pulse energy is associated with a message . 把传输的信息编码成脉冲的振幅，因而使每个预先规定的脉冲能量值对应于一个信息。
High-speed information transfer between a floppy disk and data memory frequently occurs directly between these two devices, by passing the cpu . 在软磁盘与数据存储器之间的高速信息传输，常常是跨过中央处理机直接在这两个部件之间进行的。
