At home, in the later of 1970s, prof. liu shenggang began the research on electron cyclotron maser, and later, the group leaded by prof. li hongfu has done much research work on gyrotron also, and successfully developed a first ka band third harmonic gyrotron oscillator with a permanent magnet system. and later, they have began the research on a kind of gyrotron amplifier - gyroklystron
在國內，中國電子科技大學在70年代後期，劉盛綱院士開辟了迴旋脈塞器件的研究方向，以後李宏福教授帶領下的課題組也對迴旋管進行了大量研究工作，並在「九?五」期間，成功地研製出了世界上第一支8mm三次諧波永磁包裝迴旋管。 -
The result of research into electromagnetic beheaviours of polymeric magnets as follows : all of the two agents ( acrylic acid and polycarbonate ) can reduce effectively magnetic loss and dielectric loss, moreover, acrylic acid can increase the dielectric constant of the polymeric magnet at high frequency and microwave band. on the whole, the polymeric magnet modified by acrylic acid is preferable. the research of ir spectrum and xps of the polymeric magnets have showed that modifying polymeric magnet with acrylic acid is a chemical method in the part of composing polymer, we have chosen ferrocene as raw stuff
對改性前後高分子磁體的電磁性能研究結果表明：用丙烯酸或聚碳酸酯對高分子磁體進行表面改性，兩種試劑均不影響高分子的磁導率，並且它們均有效地降低了高分子磁體的磁損耗和介電損耗，更有研究意義的足：丙烯酸使高分子磁體在高頻微波下的介電常數得到明顯提高：從總的方面來說，丙烯酸改性高分子磁體優于用聚碳酸酯改性的高分子磁體。
