TRAFFIC fatalities in the United States fell steadily from 54,600 in 1972 to
34,900 in 1992. But then they started to rise again, and by 2002 there were
38,300 traffic deaths a year.
Our performance compared with other countries has also deteriorated. America's
ranking has fallen from first to ninth over the last 30 years, with Australia,
Britain and Canada all having better records. |

T**********t 发帖数: 1604 | 18 我刚又测过一次,算了%cv,表现比较好的,是OD 0.8左右的核酸样品,%cv在1%左右,
表现差点的,是OD 0.3左右的蛋白样品,%cv大部分在5%左右,但是有一个样品的%cv超
过了10%。10%的误差对我的实验来说影响太大了。
所有的样品都是用的相同的buffer,测之前也vortex过。用的样品体积都是4uL。
相同的样品我在一台Varian Cary 100 UV-Vis spec上测过,样品体积300uL,光径1cm
,测量结果相当稳定,每个样品的%cv都低于0.5%甚至为零。
更郁闷的是,同一个样品在Varian和Nanodrop上测得的OD不一样,Nanodrop的读数比
Varian的普遍高25%以上。
我的Nanodrop肯定是需要calibration了,刚订了那个CF-1,先校准一下再看。。。不
知道calibration对reproducibility有没有帮助。

be the same as Bruker. It also depends on what probe head you have and you

家均为未来社会新的制度安排纷纷提出了各自的理论体系;其中荀子创设的“礼制”思

设计的“礼制”思想,为后来的大一统的封建帝国的经济制度与经济政策的制定,提供
了理论依据,其影响十分深远。笔者以为,荀子的“礼制”思想既是“荀学”的核心,
又是其经济思想的基石,更是具有中国传统特色的制度思想。
