原本韩立以为这是一个小瓷瓶，但是拿到手中却发现份量不对，沉甸甸的，非常重。 这片竹林看起来不怎样，但是走时间长了就觉得辛苦了，腿走着走着越来越重，渐渐的韩立必须用一只手稍微拉着竹子的茎杆向前移动，好少费些力气。

韩立抬头看了看。 最后一类人就是韩立这类人，这类人都来自偏僻的穷乡僻壤，家里一般都是靠山吃山，靠水吃水，非常的穷苦。这类人在车里是最少的了，只有五六人，神态多半畏手畏脚不敢大声言语，只是看别人放声说笑，和不时大声喧闹的那部分童子形成了鲜明的对比。

伙伴产业研究院的研报指出，国产伺服与国外品牌的差距主要体现在大功率产品缺乏、小型化产品不够精致、高精度编码器缺乏等方面。 韩立被村里人叫作“二愣子”，可人并不是真愣真傻，反而是村中首屈一指的聪明孩子，但就像其他村中的孩子一样，除了家里人外，他就很少听到有人正式叫他名字“韩立”，倒是“二愣子”“二愣子”的称呼一直伴随至今。A6V28HS22FZ2-039
