对飞行员来说，了解这种性能是很重要的，尤其是在低空飞行的时候。

Results show that existence from strong convergence of water vapor and the conditional convective instability in the middle and low troposphere probably provided the suitable environment for heavy rainfall.

分析表明，对流层中低层水汽的大量集中以及对流不稳定条件的存在可能对此类系统发展提供了有利环境，对其启动的机制作了初步的讨论，认为地形的动力强迫和地面冷锋以及低空急流扰动可能对此类系统的发生发展起了触发作用。

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。

"Plateau Eagle" advanced trainer adopts the aerodynamic arrangement of double delta wings with high lift-drag ratio, the leading edge of outside wing rotated conically and air inlet beneath both sides ribs, and has a good take-off/landing performance and subsonic/transonic speed performance in medium-low altitude.

"山鹰"高级教练机采用高升阻比双三角机翼气动布局，外翼前缘锥形扭转以及两侧肋下进气道，具有良好的起降性能和中低空亚跨音速性能。

This paper illustrates various methods which are being used and being researched both home and overseas at the present time, such as the method of steepest descent, dynamic programming method, expert system method and genetic algorithm etc.

分析了低空突防路径规划应满足的条件和特点，阐述了目前国内外正在应用和研究的几种路径规划方法：最速下降法、动态规划法、专家系统法和遗传算法等的研究现状和发展方向。

The model is run under the idealized conditions resresenting for the sea-ice diploe in the Okhotsk Sea and the Bering Sea, and the atmospheric forcing is from the data of the winter months i.

参考已有的理论和模拟研究结果，指出高纬地区低空大气的温度变化受直接热力学调整过程的影响明显，对称性响应分量明显，而高层大气温度和各层的大气位势高度变化是由直接热力学调整和间接动力过程响应所共同控制，非对称分量占主导。

The electron cloud of the highest occupied molecular orbit and the lowest unoccupied molecular orbit were calculated by Gaussian 03 software.

利用高斯03软件计算了此材料分子的最高分子占据轨道和最低空轨道上的电子分布情况。

The results showed that erectness of coupling pattern between upper-layer jet and low jet and a divergence area, which came forth in right of upper-layer jet provide favorable surrounding conditions. The most intensive moisture convergence, the strongest ascending movement and the most instable convection stratification all occurred in the rainfall center. The rainstorm occurred at the warm and wet side of the negative value center of the moist potential vorticity and relative MPV, which had certain indicative significance for the forecast of rainstorm areas.

结果表明：高低空急流的优势配置，耦合形势的建立以及高空急流右侧的强辐散场的存在为暴雨的发生提供了有利的环境条件；暴雨区中上升运动和水汽辐合均大于周围区域，中低层为对流不稳定层结；暴雨区位于湿位涡和湿相对位涡负值中心附近偏暖湿气流一侧，对暴雨落区预报有一定的指示意义。
