The numerical results of the dispersion relation show some nonlinear effects: for a fixed geometry of a waveguid, beam parameters and plasma density, the increment of the modulation parameter may lead to a slight increment of the operating frequency, However, as the modulation parameter increases further, saturation may occur and the dispersion relations are hard to be separated, it is due to the overmodulation of the microwave power, this phenomenon itself belongs to the nonlinear effects.

五。用严格的场匹配方法分析了填充等离子体的耦合腔链，研究了等离子体一腔模的形成以及&冷&带宽和&热&带宽的展宽效应。等离子体填周期性耦合腔(来源：Aae53d3BC论文网www.abclunwen.com)链后，形成周期性的截止频率为0的等离子体TG模式。如果填充的等离子体密度较低时，腔模和槽模的工作频率均有小幅上升，而带宽改善不明显。

结论VPP技术通过切口设计、腭咽弓、扁桃体切除及咽侧粘膜切除与缝合处理，实现腭咽腔软组织的重塑，有效的解除了腭咽腔的阻塞。

The constant back pressure cavity with papilionaceous slot is found to be of good economy and reliability by means of analyses for various back pressure cavities.

通过几种形式的背压腔结构分析，认为带蝶形槽的准恒定背压腔结构具有较好的经济性及可靠性。

Methods 20 healthy volunteers and 37 patients with CAD were involved in this study. Color changes resulted from CK timing and amplitude were observed at parasternal short-axis view, apical four-chamber view and two-chamber view; The percent of regional fractional area change in 30﹪ diastolic period , namely color kinesis diastolic index, were obtained using ICK software.

观察20例正常人和37例冠心病患者胸骨旁左室乳头肌短轴观、心尖四腔、两腔观各节段心肌舒张期心内膜位移引起彩阶的变化，并运用ICK定量分析软件计算出心内膜于舒张早期30﹪时间内位移的面积占整个舒张期内膜位移面积的百分比，即心内膜位移指数。

Two dimensional echocardiography (2DE) and end-systolic CK images were recorded at parasternal long axis, apical four and two-chamber views respectively.

分别记录胸骨旁左室长轴断面、胸骨旁左室乳头肌水平短轴断面、心尖四腔心断面(A4C)、心尖两腔心断面(A2C)的CK图像。

All subjects recieved the test of Two-Dimensional echocardiography and PW-TDI.3.1 LV end-diastolic diameters, RV end-diastolic diameters and inter-ventricular septum and posterior wall thicknesses were measured from the parasternal long-axis projection. LV end-systolic and diastolic volumes,RV end-systolic and diastolic volumes were obtained from the

所有入选者均行常规二维超声和组织多普勒超声心动图检查 3.1 常规二维超声心动图(two-dimensional echocardiography，2D)检查：采用胸骨旁左室长轴切面M型测量左室舒张末期前后径、右室舒张末期前后径、室间隔厚度、左室后壁厚度；心尖四腔、二腔切面面积勾画法分别测量左室、右室舒张末期容量和收缩末期容量并计算左室

Results:pedunculated omentum majus-cirded trachea transplantation ensured an early re-establishment of blood circulation of transplanted trachea and maintenance of its normal animate states; allogeneoilc transplantation of trachea activated bodys immune mechanism. resulting in a chronic process of rejection and finally leading to progressive necrosis of transplanted trachea tissues: chondroregeneration occurred at every period under perichondrium after transplantation. and the degree of regeneration was related with favorable blood circulation; the emplogyment of a supporting tube in trachea,under the condition of favorable re-establishment of early blood circulation, could preventgranulation tissue hyperplasia and keep trachea cavity unobstructed.Postgraduate Ding XiaoQuan Directed by-Lin LeShen

结果 带蒂大网膜包绕移植段气管行腹腔移植，早期重建了移植段气管的血液循环，保证了移植气管的早期成活及维持其正常生机状态；同种异体气管移植所激发机体的免疫机制，引起一个慢性排斥反应过程，导致移植段气管组织进行性坏死；软骨再生存在于移植后各个时间段，其再生程度与良好的血液循环有关；气管内支撑管的应用可防止肉芽组织增生堵塞管腔，从而保证气管管腔通畅。

Results Both the area density of stroma and the ratios of stroma to epithelium were the highest in the periurethral zone and the lowest in the supcapsular zone. While the area density of epithelium and glandular lumen in the periurethral zone was significantly lower than those of peripheral zones.The ratios of glandular lumen to epithelium among three zones were not statistically different.

结果 间质面积百分比和间质/上皮比值在尿道周围区、中间区和包膜下区中均依次递减( P ＜0.01)，而上皮和腺腔面积百分比则依次递增( P ＜0.01)；三区间腺腔/上皮比值差异无显著性。

Results While the ES lumen and perisaccular region were infiltrated with mononeuclear-phagocyte at the 3rd day post-vaccination, plasmocyte and lymphatic cells become the predominant infiltrating cells in the ES at the 7th day. The KLH in the ES lumen were phagocytized at the 3-7th day post-vaccination. S-phase cells and IgG positive cells in ES increased markedly in the 3rd day and 7-14 days post-vaccination respectively with similar localization.

结果 内耳受抗原刺激后3 d内淋巴囊囊腔和囊周区域出现单核吞噬细胞浸润，7 d内淋巴囊的浆细胞和淋巴细胞大量增加；3～7 d内淋巴囊囊腔KLH被吞噬，同时S期细胞和IgG阳性细胞逐渐增多，二者的出现部位相似。
