The tectonic rocks along the fault zone are composed of cataclastic rocks and mylonites formed in higher, middle and lower temperature. Respectively, both of structural features and rocks have the features of multiple phase's of deformation. The deformation features of main minerals in the high temperature mylonites show that: the quartz has the form of long single crystal and the fabric feature of point maximum near X axis; the feldspar has the form of recrystallization assemblage, They present a high amphibolite-granulite facies with temperature ＞600℃ and depth ＞20km. The deformation features of mylonites formed in middle temperature show that: the quartz has the form of polycrystal banding and the fabric feature of point maximum near Y axis and small circle girdle with Y rotational axis; the feldspar has the form of a coremantle structure, They reflect a high greenschist-lower amphibolite facies with temperature from 400℃ to 600℃ and depth from 15km to 20km.

其中，高温糜棱岩主要矿物变形特征组合为：石英为长矩状或长条状单晶、组构为近X轴的点极密，长石为几乎完全重结晶的集合体，形成温度＞600℃，相当于高角闪岩—麻粒岩相，形成深度＞20km；中温糜棱岩主要矿物变形特征组合为：石英为多晶条带、组构为近Y轴点极密和以Y轴为旋转轴的小圆环带，长石发育核幔结构，形成温度为400～600℃，相当于高绿片岩—低角闪岩相，形成深度为15～20km；低温糜棱岩主要矿物变形特征组合为：石英发育核幔结构、组构特征为近Z轴点极密，长石以碎裂为主，形成温度＜400℃，相当于中低绿片岩相，形成深度为8～12km；碎裂岩则主要代表了地表浅层的变形。

A circle is placed at the launch point to improve the interaction between the electron beam and the fields supported by the slow wave structure, thus to control the beam current density at the launch point, and to minimize the loss of the electron beam energy. The inaner radii of the extractor vanes are slightly larger than those of other SWS vanes, which increases the axial group velocity and enhances the microwave output power and efficiency. Implementation of two RF choke vanes stops the leakage of microwave pulse power toward the diode, and makes the device more compact than the conventional MILO.

该振荡器在阴极电子发射起点加圆环，控制此处电子束的发射密度，来减少电子能量的损耗，改善束－波互作用；逐渐加大慢波结构的后两个叶片的内半径，增大微波群速度，便于谐振腔中的能量输出，提高微波输出效率；采用两个扼流片有效地阻止了微波功率向二极管区泄漏，相应减小了器件的尺寸。
