When a piece of the International Space Station's solar array was torn in November 2007, astronaut Scott Parazynski took a ride on the station's robotic arm to patch up the live electrical panel.

2007年11月3日，美国航天员帕拉金斯基完成历时7个多小时的太空行走，成功修补了一块国际空间站太阳能电池板。由于电池板依然带电，而且破损点距离工作舱足有半个足球场远，帕拉金斯基要"走"上近一个小时，英国《泰晤士报》曾评论说这次任务是美国航天史上最危险的太空行走。

In this paper,an optimum trajectory from perilune to lunar surface is derived in terms of Pontryagin's maximum principle,which is an open-loop way.Then,an optimal nonlinear control law based on an fuzzy neural network is presented,on the basis of the optimum trajectory,due to the nonlinear mapping function of the fuzzy neural network,which is a closed-loop way.

本文根据终端着陆条件和性能指标，以由Pontryagin's极大值原理得出从近月点到月球表面的最优着陆轨迹为基础，给出一种基于模糊神经网络的非线性最优控制策略，使被控系统能够通过模糊神经网络的非线性映射能力实现某种最优的闭环制导控制。

The new plan is certainly a lot meatier than the February effort, and markets for both debt and equities gave it an initial thumbs-up, the Dow Jones Industrial Average rising by almost 500 points and credit-derivative spreads signalling a lower risk of bank defaults.

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
