The semiconductor industry has dreamed of using copper , which conducts electricity 40 percent more efficiently than aluminum , for ages 半导体业界一直有梦想能使用铜作为介质，这样可以获得比铝好40 %以上的电流传输效率。
It is shown that the vacuum interface can increase the transmission efficiency of ions and is helpful to achieve better senstivity of tofms 结果表明，接口能有效地提高离子的传输效率，使飞行时间质谱仪达到较高的灵敏度。
Therefore to increase the power factor and transmission efficience of electric net becomes an important research direction in electric system 因此提高电网的功率因数，改善电能的传输效率，便成了目前电力系统的一个重要研究方向。
The writer give a method of image progressive transmission based on wavelet transforms , it increased the efficiency of the image transmission consumedly 给出了一种基于小波变换的图像渐进传输方法，使得图像的传输效率大大提高。
But because of the higher modules loss caused by the coupling condition , the total transmission rate of the system can only reaches 65 % 但由于耦合时在空芯光纤中造成一定的高阶模式损耗，整个激光传输系统的传输效率不是很高，仅65左右。
At the end of this thesis , tentative plans are proposed for increasing the system transmission efficiency and reducing hfc network interference to qam signals 论文最后也为怎样提高系统的传输效率和降低hfc网对qam信号干扰方面提出了自己的设想。
Since the special characteristics of euv components , the imaging quality and the transmission are severely restricted by the components of eut 由于euv波段光学元件特有的光谱特性，每个光学元件的性能指标对eut的传输效率及成像质量都有重要的影响。
Then the power circuit is designed . at last , with analysis of experiment data the relation of power output and transmission efficiency of transformer is researched in detail 然后对扭矩仪的电源部分进行了设计，并通过实验数据对功放电路的输出功率和变压器的传输效率的关系作了深入的研究。
The problem with that hypothesis is that tiny radio transceivers necessarily produce minimal performance and range too , because for radio signals to transmit efficiently , antennas are required 问题的一个假设是,这个小小的无线电收发一定会产生轻微的运动和范围,因为无线电信号传输效率,需要天线
