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。

In fact, just the opposite can happen: If inlining increases a calling function's size it will reduce that caller's locality of reference, which means that overall program speed can actually worsen if the caller's inner loop no longer fits in the processor's cache.
实际上,相反的情况很可能发生:如果内嵌增加了掉用其的函数的大小则相应的调用者的引用范围会减小,意味着在当处理器的高速缓存容不下调用者的内层循环了时,程序的整体执行速度实际上降低了。

Vacuum was satisfied to the requirement of fresh-cut taro package and benefit to reduce water loss and to inhibit browning. The treatment of insufflate fresh-cut broccoli with 20mg·L-1 6-BA could delay chlorophyll reduction, inhibit ion leakage increasing and slow down the process of senescence. Fresh-cut broccoli packed with the atmosphere combination of 2.5%O2+7%CO2+90.5%N2 had high Vc and high chlorophyll content, and the senescence of the products was delayed certainly. The gas mixture of 5%O2+ 2%CO2+93%N2 could reduce the rate of respiration, chlorophyll decomposition, membrane breakdown and tissue senescence of pakchoi.
真空包装适合鲜切芋头,降低贮藏中鲜切芋头的水分损失,抑制鲜切芋头褐变发生;用20mg·L~(-1)6-BA喷洒鲜切青花菜可推迟叶绿素降解,抑制相对电导率的增加,延缓了衰老;2.5%O_2+7%CO_2+90.5%N_2MAP包装的鲜切青花菜Vc含量较高,叶绿素荧光值也较大,明显延缓了鲜切青花菜的衰老:5%O_2+2%CO_2+93%N_2混合气体抑制了青菜的呼吸作用,降低了叶绿素降解速度,减缓了细胞膜损伤及组织衰老程度。

SEM result showed that the sample had uniform phase distribution and smooth surface at dried state as well as interpenetrate network structure at hydrogel state. It was seen from the swell ing behavior curves that groups T1, T2 and T3 swelled rapidly within 10-30 minutes, and formed elastic composite hydrogel pipes. In addition, the expanding ratio of inner and outer diameter of the tube was 20%-30% and 100%-120% with swell ing, respectively. The equil ibrium water content of the hydrogel pipes increased with increase of collagen composition. Three groups of samples were immerged in PBS solution contained 2 mg/mL lysozyme at 37 for 1 month, their nozzle cracked, their wall became thin and more transparent. And also, there was small floc deposited on the tube surface.
