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。

The enhance nient of the corrosion resistance laser dadoling of the CNTs/Ni60 coatings is due to that the reserved carbon nanotubes in the coatings segregate the corrosive medium and promote N-based alloy passivation, the formed phases of the carbide and the reserved carbon nanotubes homogenous distribution in the claddings resist die corrosion.

碳纳米管／镍基激光熔覆层耐腐蚀的原因在于熔覆层保留的碳纳米管使熔覆层更加致密，隔离了腐蚀介质，促进了镍基合金的钝化，从而提高了熔覆层的耐蚀性；同时，熔覆层中保留下来的碳纳米管和被分解的碳纳米管与金属基体形成碳化物，作为增强相均匀弥散在熔覆层中，它们的存在阻止了腐蚀坑的长大，因而蚀坑较小，耐腐蚀性得到提高。

We have not draw the statistically significant factors that related to successful and failure, but the factors such as acute infection, surfacing replacement, immediate debrided after onset of symptoms, and the bacteria sensitive to antibiotic were relate to success.

Under this mechanism, in offset by changes in the temperature of the fountain solution change ink equilibrium.

根据这一机理，在胶印洋可以堵住保留润版液的温度保留火不朱不均状况。

In the lithographic, apart from maintaining the balance of ink, fountain solution of another important function is to be able to take away due to a printing plate and high-speed rotating friction so that heat plates can be maintained at a relatively stable and suitable for transfer outside the scope of the temperature.

在有火胶印洋，除了保留火不朱不均不以内，润版液的另外一个轻给息用不离是可以带行由于印版矮速回旋扭转摩擦而爆发的冷度，这样印版不离可以保留在一个比力安定的、得当油不朱迁徙的温度边界不以内。

But there's also a powerful financial reason behind the preference, and that has to do with taxes. The tax code makes Berkshire's owning 80% or more of a business far more profitable for us, proportionately, than our owning a smaller share. When a company we own all of earns $1 million after tax, the entire amount inures to our benefit. If the $1 million is upstreamed to Berkshire, we owe no tax on the dividend. And, if the earnings are retained and we were to sell the subsidiary - not likely at Berkshire!- for $1 million more than we paid for it, we would owe no capital gains tax. That's because our "tax cost" upon sale would include both what we paid for the business and all earnings it subsequently retained.

当然除此之外还有一个重大的财务理由，而且是跟税负有关，根据税法规定，持有80%以上的股权比起拥有少数股权对Berkshire要有利的多，当一家完全由我们持有的公司税后赚了100万美元，这笔钱将全数纳到我们的口袋里，Berkshire不会因为收到股利而被课任何的税，而且如果我们将盈余全数保留，之后再把这家子公司出售-当然Berkshire是不可能做这样的事，那么就算之后的卖价超过100万美元，我们也不必为此支付任何的资本利得税，原因在于我们在税法上的成本包含我们先前买下该公司的成本以及以后年度保留的所有盈余。

The forming of kyanite sequence was probably related to an arc-continent collision event during the late Paleozoic, and the andalusite sequence may result from uplifting of the medium-pressure rocks and extensive intrusions of the collision-related granites.

早期中压型变质序列保留可能是离后期热源较远，从而出现完整的中压型变质序列；由于后期低压型变质速度快，从而保留了早期中压型的特点，同时又有后期红柱石型的特点，呈现出低压型与中压型变质混合存在的现象，或表现出向低压型变质转变的趋势。
