Using finite-element method the effects of long objects, such as cage, train and metal pit prop, on electromagnetic wave cutoff frequency is researched systematically in regular tunnels, and it is shown that the long metal objects lower TE wave cutoff frequency and raise TM wave cutoff frequency.

利用有限元方法系统地研究了机车、罐笼、金属支护立柱等长列金属物体对井下规则隧道中电磁波截止频率的影响，可知长列金属物体的存在使TE波模截止频率降低，而使TM波模截止频率升高。

A new Ku-band souding system for measuring wave-height and tide-level is proposed in this paper. It is better than the wave-height meter or wave-tide meter in precision,and is easy to operate.

本文提出的Ku波段海表波高／潮位探测系统在测量精度和使用方便上优于沿用至今的波高计和浪潮仪。

All the qualitative and aethetic information are carried in the wave form including the wave top and wave peak.

而影视声的质量信息和美学信息皆载于波形之中，因此，影视伴音系统应是保持波形和波峰的高保真度录还音系统。

It seems that our wave D is in process, where we will be looking for a three wave move down from wave C top with the final target around the lower line of the triangle formation.

看来我们已在波浪D中，我们在那里寻找一个三波的下移。从波顶端，而最终目标在形成的三角地带的底部。

On the basis of different frequences, three electromagnetic wave logging methods widely used are Electromagnetic Propagated Resistivity Logging with several mega-hertz operation frequency, Ultrahigh-frequency Electromagnetic Wave Logging with above 200 mega-hertz operation frequency and High-frequency Electromagnetic Wave Logging with some dozens of megaherz operation frequency.

A carrier wave is the radio frequency wave generated at a transmitting station for the purpose of carrying the modulated frequency wave.

载波 载波是传输站为携带调制频率波而生成的一种无线频率波。

Results After improving, lithotripsy could recycle no-air water to be filled into shock wave generator. It not only increased shock wave conducting and stone breaking efficiency, but also decreasee air content in shock wave generator and outer conduct passway, and decreased bubble forming, thus reducing complication in more rational procedures.

结果：该改进后碎石机可以反复利用制备的无气水填注冲击波发生器内，减少冲击波体外传导途径内的气体含量，减少气泡形成，提高冲击波传导效率进而提高碎石效率，简化碎石操作程序使碎石过程更加合理。
