A.叶片蒸腾作用强,失水过多使气孔部分关闭,进入体内的CO2量减少 |
B.光合酶活性降低,呼吸酶不受影响,呼吸释放的CO2量大于光合固定的CO2量 |
C.叶绿体内膜上的部分光合色素被光破坏,吸收和传递光能的效率降低 |
D.光反应产物积累,产生反馈抑制,叶片转化光能的能力下降 |

y = sin x, x∈R, y∈[–1,1],周期为2π,函数图像以 x = (π/2) + kπ 为对称轴
y = arcsin x, x∈[–1,1], y∈[–π/2,π/2]
sin x = 0 ←→ arcsin x = 0
sin x = 1/2 ←→ arcsin x = π/6
sin x = √2/2 ←→ arcsin x = π/4
sin x = 1 ←→ arcsin x = π/2
