Her chest x-ray films Panels A and showed a cardiothoracic ratio of 1, splaying of the carina, and cardiac enlargement posterior to the vertebral bodies.

超声心动图提示相对于较小的左室，右室显著扩大，三尖瓣前瓣隔瓣移位，房化的右心室以及严重的三尖瓣关闭不全。

He was stunned when he opened my heart, since the structure of my mitral valve was so particular that they may had never seen it, there was no chordae tendineae on the back lobe of mitral valve, my mitral valve shaped like a cloak, medically called " cone mitral valve", I thought they may basically had seen it on textbook.

他将我的心脏一打开就傻眼了，因为我二尖瓣的结构估计他们从来都没见过，我的二尖瓣后瓣叶没有腱索，成漏斗形，医学上称为&斗形二尖瓣&，他们基本上是在教科书上见过。

Group I:Completely resection of the mitral leaflets, chordae and tendineae, and papillary muscles; group Ⅱ:Preservation of the posterior leaflets and subvalvular structures;group Ⅲ:Completely preservation of the mitral complex.4h, 24h and 48h after operation, Swan-Ganz catheter was used to measure hemodynamic index: Mean pulmonary arterial pressure,pulmonary vascular resistance,pulmonary capillary wedge pressure,systemic vascular resistance,cardiac index and left ventricular stroke work index.

组：常规MVR，切除全部二尖瓣瓣叶及其瓣下结构；Ⅱ组：保留后瓣及其瓣下组织；Ⅲ组：全部保留二尖瓣装置。术后4小时、24小时和48小时分别采用Swan-Ganz导管测定血流动力学指标：平均肺动脉压、肺毛细血管嵌压、肺血管阻力、外周血管阻力、心脏指数和左心室每搏作功指数。

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。

In order to ensure that the flap valve seat face every time to reach the appropriate position, the valve flap design in the hinge so that the valve flap is enough to swing space, and make a real disc, comprehensive engagement with the valve seat.

为了确保阀瓣每次都能到达阀座面的合适位置，阀瓣设计在铰链机构，以便阀瓣具有足够有旋启空间，并使阀瓣真正的、全面的与阀座接触。

In order to ensure that the flap valve seat face every time to reach a suitable position, the valve flap design in the hinge body to valve flap has enough to swing space, and make High Pressure Steam safety valve a real flap valve, comprehensive engagement with the valve seat.

For narrow-band signals, three uniform linear arrays, whose grating lobes are not overlapped by setting the angles between the arrays and the same pointing of main-lobes, are used and then multiplication of three patterns is operated to reduce the grating lobes of large-spaced array, which makes the array operate in broad band. For wideband or ultra-wideband signals, array pattern in the whole frequecy band is identical by designing the frequency-dependent weighting coefficients based on the Bessel function, and therefore grating lobes in high frequency parts are suppressed.

对于窄带接收信号，利用三个相交的大间距均匀线阵，通过设置它们之间的角度和主瓣指向相同使各自的栅瓣位置错开，然后把三个方向图相乘从而抑制大间距阵列栅瓣，因而适用于宽频带工作；对于宽带接收信号，利用Bessel函数设计与频率有关的加权系数，产生整个信号带宽内恒定的方向图，从而抑制了高频部分的栅瓣。

Methods The free flap donor sites with long vascular pedicle and large diameter of vessel were routinely chosed, and chose receipt vessels with large diameter and proper position, and perform vessel ananstomosis under surgical loups instead of microscope.

方法选用血管蒂较长和血管口径较粗的游离组织瓣供区，选择口径粗大和位置合适的受区血管，将游离瓣制备成外露瓣，以利于术后血供的监测，在手术放大镜下行血管吻合，部分病例同时吻合2根静脉，以确保游离瓣的静脉回流。

The chroma (C3 ) of both perianths decreased, while the hue angle of the yellow outer peri2anths increased from yellow to pale yellow, and the red inner perianths decreased from red to dark red.

黄色外瓣和红色内瓣彩度C3值均变小，黄色外瓣色相角h增大，由黄色向浅黄方向变化，而红色内瓣色相角h变小，由红色向深红方向变化。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
