 action equation
 The model is based on the wave action equation, and it includes conservative interactions with bottom and currents, generation by wind and dissipation by bottom friction and breaking. To interpret these binding experiments, we applied a simple mass action equation that assumes that the protein binds reversibly to the lipid. It is unlikely that a simple law of mass action equation can be devised that describes the calcium dependence of depolarization evoked exocytosis.
 This paper discusses the large-scale orographic contribution to the evolution process of disturbances in the nondissipative barotropic atmosphere with time-dependent and non-uniform basic zonal currents. The dispersion formula and wave action equation for the barotropic disturbances are derived by the WKBJ method . It is verified that the wave action conserves only if the basic zonal currents are steady and a W-Ely oriented mountain barrier with unbounded extent exists. Based on the wave action... This paper discusses the large-scale orographic contribution to the evolution process of disturbances in the nondissipative barotropic atmosphere with time-dependent and non-uniform basic zonal currents. The dispersion formula and wave action equation for the barotropic disturbances are derived by the WKBJ method . It is verified that the wave action conserves only if the basic zonal currents are steady and a W-Ely oriented mountain barrier with unbounded extent exists. Based on the wave action conservation thus obtained,a necessary criterion for the instbility of disturbance is derived, i.e.the disturbances may develop only if certain definite physical property equals to zero at least one point within the plane domain considered. The feature of the instability of disturbances may surely be altered due to orography.It is shown from the discussion of the time variation of the total kinetic energy of the wave packet that no direct influence of orography exerts explicitly on the perturbational kinetic energy for the nondissipative and non-uniform barotropic basic currents,i.e.the intensities of the"leading waves "and the "trailing waves" increase in the southern region and northern region of the jet stream in the westerlies respectively,and decrease in the northern and southern regions,accordingly. In other words,whether a disturbance intensifies or not depends completely upon its own structure.The decrease of the wavelengths of both leading and trailing waves is always accompanied with their axises being shifted toward the W-E direction,whereas the increase of their wavelengths always takes place when their axises move toward the N-S direction.It has also been pointed out that the relationship between the intensification or attenuation of a barotropic disturbance and the increase or decrease of its wavelength is not entirely definite but conditional,depending on the curvatures of both orographic height and basic zonal current profiles and the shearing of the basic zonal currents. 本文着重研究大地形对正压大气迭加在非均匀纬向基本气流上挑动演变的影响。用WKBJ方法推导了正压扰动的频率和频散关系以及波作用量所满足的方程。当基本流场定常且存在无限长的东西向山脉时,则有波作用量守恒。据此,获得了正压不稳定的必要条件:即在所考察的平面域内至少在某点或某些点上含地形效应的某一物理量等于零,扰动就可能得到发展。对波包动能的倚时变化的讨论得知,在无摩擦正压纬向非均匀基流的情形,地形对扰动动能并无直接影响,即导波和曳波分别在西风急流的南侧和北侧得到加强,并分别在西风急流的北侧和南侧强度减弱。扰动的发展由扰动的结构所决定。导波和曳波的波长缩短总伴同其轴线倾向于东西向相联系,而它们的波长伸长总是与其轴线倾向于南北向同时发生。还指出,正压扰动的加强(或减弱)与波长的伸长(或缩短)不是必然的联系,它的成立是有条件的。 In this paper, the wave action equation of internal inertial gravity wave is obtained by using Lagrange variational principles, which is different with that one by WKB method, however, the result obtained in this paper is consistent with observations in the atmosphere. 本文利用Lagrange变分导出了惯性重力内波的波作用量方程,这种方程与用KWB方法所得到的惯性重力内波的波作用量方程在形式上有所不同,但所得到的结果却与观测事实是一致的。 In this paper,the Hamiltonian function of meso-scale symmetric motion is constructed.and the sufficient conditions of symmetric motion is derived with the application of variational principle. Furthermore,the wave action equation of symmetric motion in the slowly varing media is obtained by using Lagrange mean variation, which is consistent with that obtained by the WKB method.
