摘要

在随桨叶旋转的坐标系中，用有限差分法求解非守恒格式的全势方程，建立了一个适

对有升力桨叶，也分别就悬停及前飞状态下的桨叶剖面压力分布进行了计算，通过与试验

Abstract A numerical method is established for the calculation o

ted by using finitedifference methods under the coordinate fixed on the blades

. Jameson′s rotating finitedifference methods is adopted and the wake effect

is considered by introducing an equivalent angle of attack. As examples, the com

putations are carried out for the nonlifting rotors with straighttip and

swepttip, as well as lifting rotors under the conditions of hovering and high

speed foward flight. The reliability of this method is verified by compared wi

Abstract Up till now there is no clear cut definition of theory for propagation

velocity of coherent structure in wall region of

a turbulent flow. A model of a single coherent structure is proposed,

using the idea of resonant triad of theory of hydrodynamic stability. This paper

investigates the coherent structure in the wall region of a turbulent fl

摘要

对面向agent的程序设计语言AOPLID进行时态扩充，使之能表达并处理带时间

参数的并发行动。对经典情境演算进行适当改造，使之能描述含时间变元的行动，因为持续

行动一般可认为是具有瞬时开始行动和瞬时终止行动的过程，因此可以将一个持

续动作分解为两个时间上互不相交的瞬时动作，再引入一个新的关系流刻画这两个瞬时动作

的执行情况，从而可在扩充后的情境演算中表达带时间参数的并发行动；对已有的AO

PLID离线解释器进行了适当改造与扩充，使之能执行带时间变元的AOPLID程序；通过实例说

明了该方法以及扩充后的一些语言特色。

Abstract Aims to give a temporal extension of the agentoriente

d programming language AOPLID so as to represent and process concurren

t actions with the time arguments. Firstly, the classical situation calculus is

extended to the temporal situation calculus to enable a treatment of actions

with explicit time. Because the actions with duration can be viewed as proc

esses that initiate and terminate by instantaneous actions, a duratio

n action can be decomposed into two instantaneous actions that do not interlap w

ith each other. A new relational flow is also introduced to describe the exec

utive account of the two instantaneous actions, so that concurrent processes wi

th explicit time can be represente

d in the extended situation calculus. Secondly, the existed offline interprete

r fo

r AOPLID is modified and expanded in order to execute an AOPLID program with the

time arguments. Finally, the examples are given to demonstrate the methods and

the features of the extended language.

本文提出的选取测量矢量加入样本集的EMP方法，有效地减少了样本集中样本矢量的数目，

Abstract The classical theory of synchronous generator， with the vector analys

is， is adopted to describe the voltage regulation

characteristic of rare earth permanent magnet (REPM) generators. The mathematica

l calculation model is established and the rule， in which the voltage regulatio

n c

haracteristic is affected by parameters， is discussed. The analysis shows that

it is the daxis armature reactance (Xad), besides power factor, w

hich has the biggest influence on the voltage regulation characteristic. It also

sho

ws that leak resistance and reactance have little influence on the intrinsic vol

tage regulation rate. The salient pole coefficient markedly affects the voltage

regulation characteristic only with high power factor. So it is necessary to des

ign Xad as small as possible to get low intrinsic voltage regulation

rate. The m

athematical calculation model is simple and practical and has believable accurac

y proved by the data comparison of calculation and test. The model i

s helpful

to design REPM generators with small voltage regulation rate.
