It shows that it is possible to increase the start oscillation length by tailoring magnetic field's amplitude and its period without changing the synchronous condition of the fundamental wave;in the meantime, when there are two or more azimuthally asymmetric space harmonics in the high power broad-band helix TWT, the influences of the Pierce's gain parameter, space charge parameter, and loss parameter on the start oscillation length and real starting asynchronous velocity parameter are also analyzed.

研究结果表明：改变聚焦磁场的幅值或周期来增加起振长度是可能的，而且不会改变基波的互作用条件。与此同时，对起振长度、初始非同步速度参量随皮尔斯增益参量、空间电荷参量、损耗参量等的变化，以及在超宽带行波管中当存在两个或多个角向非对称空间谐波时，起振长度、初始非同步速度参量随周期永久聚焦磁场的变化进行了研究。

When B-ultrasound and X-ray were used combinedly,diagnosis rate and accuracy were elevated.Surgical treatment should be applied to cases diagnosed determinedly.Cholecystectomy is an effective method to treat cholecystolethiasis and choledochotomy should be controlled strictly in use.

小儿胆石症缺乏典型症状，对有腹痛和黄疸者首选B超检查，结合腹部X线平片可提高诊断率；诊断确定应行手术治疗，胆囊切除是治疗胆囊结石较好术式，胆总管切开应严格掌握指征。

The misdiagnosis rate of cornual pregnancy is high and its risk is also high so that the routine examination of B-mode ultrasound should be performed during the early pregnancy period.

宫角妊娠误诊率高，危险性大，故早孕期间应常规行B超检查，结合腹腔镜手术可以早期诊断，早治疗。

Objective To evaluate the diagnosis and treatment of gastrointestinal stromal tumor.

Results Microscopically, different degrees of hepatocytic degenerative changes and hyperplasic fibrous tissue and typical false lobule formation could be seen. Timm's staining result showed uneven distributed black granular deposits in the hepatocytes. No specific PAS staining was observed. Utrastructurally, the mitochondria were increased in volume and dramatically different in shape. The number of lysomes were increased.

结果 光镜下肝细胞表现为不同程度的退行性变，胶原纤维增生以及典型假小叶形成；Timm's染色阳性，发现不均匀分布黑色颗粒或团块样物质沉积；PAS染色则普遍缺乏特异性染色；超微结构显示线粒体形态多样，体积增大，溶酶体增多，粗面内质网管腔扩张，附着核糖体的脱颗粒，以及胞质水肿，质膜溶解。
