查询词典 level

When the conditional instability lies in the lower level and conditional symmetric instability in the upper level , the circulation will have vertical updrafts in the lower level and slantwise updrafts in the upper level .

当低层和高层出现条件不稳定，中间呈条件对称不稳定或弱稳定度层结时，从低层到高层出现较深厚的垂直上升气流，湿重力不稳定能量的释放导致了云带的形成。

The conditional symmetry instability is the intermediate process between the stable and instable states of the atmosphere. The evolution of the atmosphere from the stable to unstable state or from unstable to stable state comes through two stages. The convective-symmetric instability circulation is related with the state and type of the instability. When the conditional instability lies in the lower level and conditional symmetric instability in the upper level, the circulation will have vertical updrafts in the lower level and slantwise updrafts in the upper level. The release of conditional symmetric instability gives rise to a mesoscale rain belt.

结果表明：条件对称不稳定是大气稳定状态和条件不稳定状态之间的中间纽带，大气由稳定向不稳定或者由不稳定向稳定的演变均通过条件对称不稳定来实现；对流对称不稳定环流的形成与不稳定层的配置有关，当低层为条件不稳定而高层叠加深厚的条件对称不稳定时，对流对称不稳定环流低层出现垂直上升气流，高层出现范围较广的倾斜上升气流，对称不稳定能量释放产生中尺度云带。

In DMMCS, there is an alternative distribution of inertial instability column and inertial stability column, at the west and south, there lie negative CVV columns, while negative CVV column is beneficial to deep moist convection.(4) The strong slantwise convection induced by inertial instability, baroclinic instability and conditional symmetry instability will enhance the upper level southerly component. Because of the appearance of the compensated downdraft at the low level of the south side of DMMCS, the low level southerly is intensified, the enhancement of upper- and low-level cores are in favor of the development of DMMCS. And that will do favor for the reinforcement and maintenance of inertial instability, baroclinic instability and conditional symmetry instability, it is a positive feedback process.

深湿对流系统中高层西侧为负MPV2 柱，东侧为正MPV2 柱；(3)深湿对流系统中惯性不稳定柱与惯性稳定柱相间分布，西侧为负CVV 柱，东侧为正CVV 柱，负CVV 柱对深湿对流起激发作用；（4）惯性不稳定、湿倾斜不稳定和条件不稳定产生强的倾斜式对流，而强的倾斜式上升运动加强了深对流系统北侧高层的南风分量，因深对流系统南侧低层出现补偿性下沉气流，因而低层南风加强，高低空急流中心的加强会进一步加强对流的发展，使得惯性不稳定、湿倾斜不稳定和条件不稳定增强和维持，这是一个正反馈过程。

手术人员一方面必须非常熟悉胃十二指肠及其临近器官的正常解剖结构，并在此理论基础指导下进行手术，另一方面还必须具备扎实过硬的操作和对病人高度负责的职业态度，这样才可能尽量避免术中邻近脏器的损伤和线结被剪断，术后缝线脱落，以及减少出血等情况的发生。在施行胃大部切除术时，对切除胃的范围还没有一个精确的定量手段，只能根据临床经验进行掌握。胃切除过多，术后会导致病人胃肠功能不足，出现营养不良，甚至可以出现粒细胞减少而引起腹泻。切除胃过少又可能达不到治疗目的，出现原发病的复发，如溃疡复发，残胃癌等。

The result showed:leptin level was positive related with the level of E2,P in mammary only duringthe pregnancy,leptin level was positive to the level of Prl GH during the pregnancy-lactation cycle Hint:leptin in mammary might promote the development of mammary duct and gland bubble with E2,P;leptin in mammary might promote the mammary development and start secretion of milk with Prl; leptin in mammary and GH were promoting the growth during mammary developmen,strengthen the action to promote the gland bubble development with Prl,mighe play an important role in the modulation of the mammary gland development.

提示，乳腺组织leptin很可能在妊娠期协同E2、P作用于乳腺导管和腺泡的生长发育；乳腺组织leptin与Prl很可能共同在青春期和妊娠期促进乳腺发育及在妊娠末期启动泌乳，乳腺发育过程中乳腺组织GH很可能与乳腺组织leptin共同发挥其促生长作用，加强Prl在妊娠期的促进腺泡发育的作用，直接或间接的调节乳腺的发育。
