Results The detecting rates of the displacement of the mitral coaptation point ,the flail partial mitral leaflets,the coarse and erratic flutter of flail leaflets, the flicking mitral chordae tendineae with coarse and erratic flutter and the vegetation by TEE and TTE with 2-D were 100%and 94.3%, 100%and 65.7%, 85.7%and 54.3%, 77.1%and48.6%, 100%and33.3%, respectively.With color Doppler imaging,eccentric wall jets or eccentric-centric jets were all detected by TEE and TTE, respectively. The regurgitant volume based on PISA method by TEE and TTE was(2025±402)and (607±268)ml/min,respectively.

Methods The design of burn scar flaps in tendo calcaneus was improved. In virtue of accessary transverse incision, ankle joints were reposited, without incision or free liberation of the internal side's scar flap.Results Improved scar flaps in tendo calcaneus met the need of ankle joints' functional reposition with an additional benefit that internal scar flaps were not prone to necrosis.

Background— Mild commissural mitral regurgitation is associated with significantly higher restenosis-free surial after percutaneous mitral aluloplasty, which suggests that different mechanisms of significant MR after PM may hae different clinical courses.

背景 经皮二尖瓣成形术后轻度的联和部二尖瓣返流患者术后无再狭窄生存率明显较高，提示着成形术后不同机制的显著二尖瓣返流有不同的临床进程，因此对成形术后显著二尖瓣返流患者的长期预后因素进行了分析

Methods The hearts of171adult corpses of Chinese Han nationalitywere observed for the forms of all the commissural region of the main valves and the commissur-al region of main and accessory valves.

对171例中国汉族成人心脏行右房室瓣主瓣连合区和主副瓣连合区的形态学观测。

MethodsRetrospective analysis of the clinical data,surgical method and prognosis in 43 cases of epidural hematoma straddling sinus was made.All the 43 cases underwent bone flap craniotomy straddling sinus,reposited the bone flap.

方法对43例骑跨静脉窦硬膜外血肿病例的临床资料、手术方式和预后进行回顾性分析。43例患者均采用跨窦骨瓣开颅，骨瓣复位，窦旁硬脑膜悬吊于骨瓣相应位置的骨孔上。

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。
