小燕子,穿花衣。

家燕的体型小巧,树麻雀和它比起来都会显得大一些。

离得远,它们看起来黑黢黢的,下巴一撮儿红色很明显,离得近,在阳光的照射下,羽毛本身有色素沉淀,除此以外,羽毛的物理特质使得在一些角度看,因散射、干涉或衍射的产生出的结构色,复合呈现出五彩斑斓的蓝色。

照片中可以看到羽毛部分:从结构上分类看是正羽,从功能上分类是飞羽。

春季,燕子忙着筑巢抚育下一代,因此,它们会为了找寻建筑材料,多次往返很是辛苦。

马上它们就要多起来了~

That strategy is the acquisition of a value-priced company by a growth company. Using the growth company's higher-priced stock for the acquisition can produce outsized revenue and earnings growth. Even better is the use of cash, particularly in a growth period when financial aggressiveness is accepted and even positively viewed.he key public rationale behind this strategy is synergy - the 1+1=3 view. In many cases, synergy does occur and is valuable. However, in other cases, particularly as the strategy gains popularity, it doesn't.
