查询词典 cutting down

In order to cutting down the cost, flocculation of recombined Erwinia carotovora-Eccl3B cell from broth, influence of temperature, pH and oxidants on the separation of PHB were studied; and the method which measure the molecular weight of PHB by intrinsic viscosity was also studied; furthermore, a phenomenon was found that insolubility of PHB in chloroform can be changed by pretreated at over 120℃ for the fist time, and the mechanism of this phenomenon was explored.

为了降低成本，提高生产效率，本文针对发酵法生产PHB过程中存在的，发酵液难以分离沉淀，非有机溶剂提取PHB时分子量严重降低等问题，进行了发酵液的絮凝，及温度、pH、氧化剂对提取PHB影响的研究。并对粘度法测定PHB分子量的方法进行了研究，同时，对于研究过程中发现的，加热后PHB在三氯甲烷中的溶解性变化及其原因进行了探索。

As one of reproductive energy, because of technique enhancing, increscent capacity and price cutting down, wind energy becomes more and more popular than others reproductive energy such as solar energy and ocean energy.

风电作为可再生能源的一种，之所以在新能源中能脱颖而出，主要在于风电技术的不断提高，装机容量的不断加大，风电成本的不断降低，而这样的进步和发展，是其它可再生能源和新能源如太阳能、海洋能等都无法媲美的，正因为此，研究风力发电技术成为了当今能源开发的热门。

When sea level drops, forced by Kelioli, river mouth extends eastward and migrates southward, cutting down deeply. On the contrary, when sea level rises rapidly, river mouth jumps northward dramatically and moves westward, goes backward step by step. While sea level changes and river discharge is harmnize, as the geological depositional center is moving eastward and southward, driving by Keliolli and longshore drift, river mouth moves southward slowly, keeps relative stability, and forms the delta towards south slightly.

海面下降过程中，河流河口在科氏力作用下，南移东伸，下切迅速；反之，海面快速上升的过程中，河口则迅速北跳西移，逐步退缩；两者力量对比相当时，在沉降盆地沉降中心东移，并向南掀斜的背景下，在科氏力与沿岸流作用下，发育微微南偏的三角洲，河口缓慢南移，相对稳定。

The operational pathway by cutting down the perihepatic ligament next to the superior border of liver is a quick way with little bleeding, no hurting for diaphragm and hepatic vein, and the secundum porta hepatic can be showed clearly.

观察肝静脉的汇入情况。2结果肝的第二肝门是指肝顶部下腔静脉窝上端，有肝左、中、右静脉和一些附加的肝小静脉注入下腔静脉近端处。

The faciform ligament is an important sign of laparoscopic liver surgery and a way of collateral circulation of liver. The superior liver artery found and named in this research can be an important sign to judge the position of hepatic vein. The operation pathway by cutting down the perihepatic ligament next to the superior border of liver is a quick way with little blood. It is difficult to hurt diaphragm and hepatic vein, and the secundum porta hepatic can be showed clearly. As a rule, we break the hepatic vein in the hepatic parenchyma on laparoscopic hepatectomy. But in some situation, extrahepatic treatment was used.

镰状韧带是腹腔镜肝脏外科入路的重要标志，是肝脏侧枝循环的重要途径；本文所发现并命名的肝上动脉可以作为判定肝静脉位置的重要标志；紧贴肝上缘打开肝周韧带，不易损伤膈肌和肝静脉，出血少、速度快，可以使第二肝门获得良好的手术显露；腹腔镜肝切除时一般在肝实质内切断肝静脉，在个别情况也可以预先在第二肝门结扎切断肝静脉。

Although him EA had undertaken a few rounds cutting down the member of persons employed, but the attitude that the developer that attend the meeting showed those who seem to want an EA CEO to advertise Fu Zhu to carry out really, they state 2009 they will continue in succession the play with new development of investment of stick one's chin out.
