论文摘要
在国际空间站进行的最新实验突出了叶片振荡的明显周期性以及与lunisolar力的节奏变化相关的其他生物学现象。这些事件类似于地球上发生的事件，但在较短的时间内影响更大。在可能的干扰中，除了强迫或自我存在的振荡外，参数共振出现是由小术语引起的。在微观或介观植物通道中，充满SAP和空气蒸气的液体发生了较小的周期性变化。界面不稳定性验证了由雷利 - 泰勒稳定性模型产生的Mathieu的二阶微分方程。这些不稳定性出现在月球围绕地球旋转和国际空间站革命期间。它们在根，茎和叶网络中产生压力和SAP运动的冲动。该模型可以解释月球潮对植物生长的影响。地球周围的月球轨道的偏心率在月球轨迹的上流和围角群之间产生了重要的区别，因此潮汐效应可能取决于月球与地球之间的距离。
Recent experiments conducted in the International Space Station highlight the apparent periodicity of leaf oscillations and other biological phenomena associated with rhythmic variations of lunisolar forces. These events are similar to those occurring on Earth, but with greater effects over a shorter period of time. Among the possible disturbances, other than forced or self-existing oscillations, parametric resonances appear caused by a small periodic term; such is the case of fluids subjected to small periodic variations in gravitational forces in microscopic or mesoscopic plant channels filled with sap and air-vapor. The interface instabilities verify a Mathieu's second order differential equation resulting from a Rayleigh-Taylor stability model. These instabilities appear during the Moon's rotation around the Earth and during the revolution of the International Space Station. They create impulses of pressure and sap movements in the network of roots, stems and leaves. The model can explain the effects of the lunar tide on plant growth. The eccentricity of the lunar orbit around the Earth creates an important difference between the apogee and perigee of the Moon's trajectory and therefore the tidal effects can depend on the distance between the Moon and the Earth.
