查询词典 planform

Numerical simulation results show that the typical features of primary flow, secondary flow and velocity redistribution in natural river bends are closely related to the special planform and flow depth conditions of natural river meanders. The lateral redistribution of flow is significant when water depth is small. The main stream approaches the concave bank upstream the bend vertex when river width is small.

数值试验结果表明，自然河流河弯中的主流、二次环流和流速重分布特征是与自然河弯的特殊几何形态特征、水深条件紧密相连的，水深越小则流速沿横向的重分布越为显著；河宽越小则水流动力轴线在凹岸的顶冲点越为提前。

The study also investigates two types of planform modifications: 1. tapered vanes; 2. forward-swept and aft-swept vanes. The results show that with the same surface areas, forward-swept vanes and tapered vanes with constant height and larger length are able to improve the function on sediment control.

本研究同时探讨板顶束缩及板顶前后倾两种板形的改变，结果显示在固定面积的情况下，板高固定与板长改变的板顶束缩及板顶前倾两种形状的改变可增进潜板的效能，在决定潜板形状时，可参照二者的变化加以评估。

Ln this paper the effect of the position and planform of the canard wing on the burst process of the leading edge vortices over thedouble delta wing and the aerodynamic characteristics of the fighterconfiguration with the double delta wing are presented Furthermore,optimum fighter with the canard-double delta wing has been given.

本文给出了鸭翼对双三角翼气动特性及涡的发展和破裂过程的影响，进而分析了鸭翼位置、平面形状对全机气动特性影响的机理，并提出了合理的鸭翼双三角翼布局形式。

DESIGN FEATURES:"Strap-on" personal helicopter with contrarotating twin blades of tapered planform and fixed pitch (thus no autorotation capability - replaced by ballistic parachute, if desired).

设计特点："捆绑式"的俯视图的反向的锥形和固定摊位（因此没有自转能力双刀片个人直升机-由弹道导弹降落伞取代，如果需要的话）。

Institute (Chengdu Aircraft Design Institute) initiated studied on the "tailless delta-canard" wing planform as early as the late 1960s.

611所早在1960年代末就开始研究鸭式无尾三角翼布局飞行平台。

The new technique allows First Order Shear Deformation Plate Theory orClassical Plate Theory to be used for modeling built-up wing structures, sandwich wing structures or the wing structures which the volume between upper and lower skin is empty or solid with a'general planform.

根据翼面的几何和结构特点，新技术能够自主选择经典板理论(Classical Plate Theory，简称CPT)或第一阶剪切变形板理论(First Order Shear Deformation Plate Theory，简称FSDPT)，具有模拟空心、实心、夹层和组合等形式的翼面结构及三维建模的能力。

Computer network management technology ,the relationship between WEB,CORBA,XML and network management are also discussed in this paper. By integrating the benefits of these technologies,we bring forward the network management framework based on WEB/CORBA/Java. This architecture is of excellent characters,such as high expansibility,high retractility,standard interface,multi-planform sustainability.

接着又对计算机网络管理实现技术进行了分析，探讨了当前发展中的新技术——WEB技术、CORBA技术与XML等技术与网络管理的关系，从而提出了基于WEB／CORBA/Java的网络管理框架，该框架具有可扩展性强、高可伸缩性、界面统一、支持多种平台环境等特点。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
