比较当酶分别在竞争性抑制剂、非竞争性抑制剂及反竞争性抑制剂存在时其对应Km与Vm的变化情况。
今有一收缩均匀的矩形风口,截面均为(0.05×2)m2,出口流速为10m/s。求距孔口2.0m处的射流轴心速度vm、质量平均流速v2及流量Qv。
在非线性跟驰模型中选取适当的参数,推导格林希尔治(Greenshields)模型。设定k=kj时,v=0;k=0时,v=vf。km、vm为最大流量时所对应的密度和速度,忽略反应时间。
已知A,B二组分在同一操作条件下的分配系数为45和50,柱相比β(β=Vm/VB)为30,线速度为7 cm,设塔板厚度为0.5 mm,要使二者分离度为1.0,求: (1)所需分析时间为多少? (2)要达到完全分离,分离时间又为多少?
I can just()a glance at the rest.
A.get
B.look

用硒光电池制作照度计,下图为电路原理图,已知硒光电池在100lx照度下,最佳功率输出时Vm=0.3V,Im=I.5mA。选用100μA表头改装指示照度值,表头内阻RM为1kΩ,若指针满刻度值为100lx,计算电阻R1和R2的值。
A.Nice, short sentences.
B.A lot of pictures.
