Attenuation vs repression The trp operon is regulated by both repression(which determines whether transcription will occur or not)and attenuation.Other operons for amino acid biosynthetic pathways may also be regulated by both repression and attenuation or only by attenuation.

弱化作用与阻遏作用的比较 trp操纵子同时受到弱化作用和阻碍作用的调控，其他氨基酸生物合成途径的操纵子也可能受弱化作用和阻碍作用的调控，或者仅有弱化作用调控。

At last , some investgation is made to change about elementary constant of the universe in today ,which demonstrates that elementary constant of the universe in today would change at a ratio of 2.3387723548904887*1050 per year which means that elementary constant of the universe in today would remain as an constant unchanged within one million years if its accuracy fix on the 4th digit after radix point of 7.7577806787995708*1060 As a reminder , both elementary constant of the unvierse elementary constant of the unvierse in today have nothing to do with the cosmic constant introduced by Mr.

基本宇宙常数是一个变化的物理常数，其数值变化的速率为：2.3387723548904887*1050 ，与今天基本宇宙常数7.7577806787995708*1060 相比较，如果在保持今天宇宙常数的数量级不变的情况下将精确度选定在小数点后第4位，那么今天基本宇宙常数将在100万年之内保持不变。

Afterwards, we propose a new constant coefficients measurement method in dynamic equation of robot manipulators, this measurement method includes three groups of experiments: group one, let each joint of robot manipulator keep static to measure the constant coefficients in gravity term of dynamic equation and Coulomb frictional torque, group two: let only one joint of robot manipulator move at a constant velocity to measure the viscous frictional coefficient and constant coefficients in effective inertia of dynamic equation, group three: let only one joint of robot manipulator move at constant acceleration at a time to measure constant coefficients in Coriolis and centrifugal term and coupling inertia of dynamic equation.

让操作器单个关节恒速运动，在对驱动系统中传动机构，减速装置和电感系数综合考虑的基础上，这组实验对粘滞摩擦系数及有效惯量中常数系数进行测量。这种测量方法只要求旋转关节的驱动电机施加恒定电压，回转关节驱动电机施加正弦波电压。3。让操作器单个关节恒加速运动，这组实验测量动力学方程中哥氏力、离心力项和耦合惯量项中的常数系数，这种测量方法只要求单个关节匀加速运动，而其它各关节保持静止，这种测量方法虽然要求关节匀加速运动，但不必进行关节角加速度检测，而只需进行关节角位移和角速度检测即可，输入量直接给定为输入电压。
