如果 f (x) 与 g (x) 均为周期函数，判断其相加后的周期性？ 7 两个非周期函数f与g，或者一个周期f和一个非周期函数g，f+g、f*g可能是周期函数也可能不是。 8 函数的其他运算如复合、求逆、平移、取绝对值等保函数周期性吗？ 举个例子，若f (x)为周期函数，则｜f (x)｜一定为周期函数吗？ 一定是。 注意逆命题不一定
比较G蛋白耦联受体介导的几种信号通路之间的异同？ - 知乎 （2）G蛋白 ① 刺激型G蛋白称为Gs蛋白（stimulatory protein，Gs protein），接受了激活型受体的信号后，激活腺苷酸环化酶，提高cAMP的浓度。 ② 抑制型G蛋白称为G1蛋白（inhibitory G－proteins，G1 proteins），接受抑制型受体的信号后，抑制腺苷酸环化酶，减少cAMP的产生。
