Fruit dry, of two mericarps united by their faces, and usually attached to a central axis, from which the mericarps separate at maturity; mericarps are variously flattened dorsally, laterally or terete; each mericarp has 5 primary ribs, one down the back, two on the edges near the commissure, and two between the dorsal and lateral ribs, occasionally with four secondary ribs alternating with the primary, the ribs filiform to broadly winged, thin or corky; vittae usually present in the furrow (intervals between the ribs sometimes called the valleculae) and on the commissure face, rarely also in the pericarp, sometimes obscure.

为了评价牙周刺激带骨瓣移植结合根面枸橡酸处理，在整复由于牙龈退缩所丧失牙周组织方面的临床效果：观察成年动物的骨膜对有控制的外科穿刺性损伤及动物实验性刺激带骨瓣结合酸处理术后的组织学反应，特别注意牙槽骨的再生情况。

In all,10 patients were cured after mean follow-up 15.3±12.8 months.The causes of RFCA failure were demonstrated in surgical operation.In 3 patients without structural heart disease,ablation catheters were not located in distinct target sites during ablation of 2 left posteroseptal pathways and 1 right posterior wall pathway.In 2 cases of Ebstein?s anomaly,ablations were failed by serious tricuspid regurgitation and AP at epicardium.In one case with rhumatic valvular disease,ablation catheter did not achieve mitral annulus because of pathologic changes.Other 4 cases with congenital heart disease were associated with anotomical anomaly and serious hemodynamic disturbance.

s畸形合并房间隔缺损，1例为重度三尖瓣返流使消融电极不能稳定贴靠靶点，另1例为AP靠近心外膜面而致RFCA失败；1例风湿性心脏病联合瓣膜病因瓣膜及瓣下结构病理改变致RFCA失败；1例重度二尖瓣返流RFCA失败与病人不能耐受RFCA与AP定位于24区消融导管难以抵达有关；先天性心脏病大房间隔缺损、重度主动脉关闭不全及矫正性大动脉转位右旋心伴三尖瓣返流各1例，RFCA失败与解剖畸形、心内大分流等血液动力学障碍有关。

To overcome the drawbacks in the weight and cost of the antenna with the corrugated soft surface, a new patch antenna with patch rings is designed. Its weight is about 1/4 less than the antenna with the corrugated soft surface and it is inexpensive. Good experimental results are obtained. The radiation pattern of the antenna is more rotationally symmetric, and a more reduction on the sidelobe levels of the antenna is achieved as compared to the antenna with the corrugated soft surface. In conclusion, in the present thesis both theoretical and experimental research works have been carried out intensively on patch antennas based on photonic-bandgap structures.

为了克服皱褶软表面天线份量重，加工费用贵等缺点，我们对空气介质的皱褶圆环结构软表面天线进行了改进，将周期分布的皱褶圆环平面化，并保持结构的软表面特性，设计出了一种新的平面圆环结构的软表面天线并进行了实验研究，加工的平面圆环结构天线比皱褶圆环结构天线重量减轻了约1/4，加工费用大大降低，所取得的实验结果显示，该平面圆环结构软表面天线的方向图的轴对称性得到了改善，在俯仰角从0°～-90°的范围内天线H面的波束与E面重合，与皱褶圆环结构相比，天线的旁瓣和背瓣受到了更大的抑制，E面方向图上+120°方向的旁瓣被明显削弱。

Moreover, the electromagnetic flux density and meniscus height increase in the form of chequerboard with increasing of slit number. The numerical results can exactly illuminate some experimental phenomena, and enrich the theoretical foundation of soft-contact continuous casting technology. In practice, a softcontact mold with slit number of 16 or 24 is recommended, the suggested frequency is around 20kHz, and the slit width is about 1mm.

结果表明：钢液对结晶器内的电磁场分布有很大影响；发现了磁感应强度和弯月面高度随电源频率增加而增大的频率范围、磁感应强度和弯月面高度随切缝数目增加呈&锯齿状&增大的规律；研究结果合理地解释了一些实验现象，完善了软接触结晶器电磁连铸技术的理论基础；建议在实际应用中采用分瓣数为16或24分瓣数的结晶器，电源频率应控制在20kHz左右，切缝宽度应控制在1mm左右。
