描述：该课程的下半年开始，侧重于黑洞和相关性。

But for the sake of precision, it makes sense to define a second type of escape velocity, individual escape velocity.

辅助引擎可操作，但无法加速到逃逸速度。

According to this understanding, this thesis tries to modify PSO algorithm in order to improve its quality of solutions. The main approches include: using uniform design to ensure the uniform distribution of initial particles in the design space; adding mutation operation to increase the diversity of particles; decreasing the maximum velocity limitation and the velocity inertia automatically to balance the local and the global search efforts; developing a new approach to treat the design variables exceeding the bounds; using extensive local searches to escape local minimum. The overall effect of these approaches can yield better results for most test problems.

有鉴於此，本文针对粒子群演化法之流程参考相关文献并稍作改变，使得粒子群演算法在结果的收敛上更具优势，本文的主要改进的方法包括：应用均匀设计的概念使得初始的粒子可以更均匀地分布在空间上；利用突变增加粒子之间的差异性与多样性；利用适当控制的最大速度限制及惯性权重控制，达到区域搜寻与全域搜寻的效果；应用新的边界处理机制处理设计变数超过上、下限的问题；利用区域强化搜寻针对粒子附近地区，再作进一步的搜索以得到更佳之结果；将各种方法综合后配合粒子群演算法使用，可以得到不错的结果。

Prominence a wide variety of shapes and movement characteristics, in general can be divided into four categories:(1) quiet prominence, change is slow, longer life expectancy, up to the number, and with the presence of sunspots related to sunspots for a long time, it is also a little more;(2) the activities of prominence, from a quiet prominence changes years, the movement is faster, but lower than the sun's surface escape velocity, so mostly circular, the material eventually thrown off the plane back to Japan;(3) the outbreak of prominence, activities of the most intense one, and sometimes velocity can exceed the Sun the surface escape velocity, reaching 100 km D seconds, or even higher altitudes of up to one million kilometers, 20,000 kilometers thick;(4) crown-shaped prominence, looks like clouds, is a rather exceptional prominence.

日珥有各种各样的形状和运动特征，大体上可分为四类：（1）宁静日珥，变化缓慢，寿命较长，可达数目，并与黑子的存在有关，黑子多时，它也多一些；（2）活动日珥，由宁静日珥变化而来，运动速度较快，但低于太阳表面逃逸速度，因此多为环形，抛出的物质最终仍落回日面；（3）爆发日珥，活动最激烈的一种，有时运动速度可超过太阳表面逃逸速度，达100公里D秒，甚至更高，高度可达上百万公里，厚达2万公里；（4）冕形日珥，貌似浮云，是一种比较特殊的日珥。

外逸层地球大气层的最外圈，位于热层之上，并向太空延展几千公里，在那里分子具有足够的速度可以逃出地球的吸引力

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
