惯性运动

We must use inertial component as feedback measuring sensor of velocity- stabilized loop to reduce regulation motion of carrier (such as plane, missile .etc) of photoelectric system carried by plane, and make a gyro stabilized control system.

In this article, I start from the foundation of classical physics-uniform linear motion, then extend to the foundation of modern physics, illustrating through solid evidence, the notion that 'the change of state' and 'the change of location' of inertial frame are two different concepts as well as my idea that in inertia system the reference system for 'the change of location' will not necessarily exist independently from natural object.

本文中我大体上从经典物理学基础的匀速直线运动开始并延伸到近代物理学的基础，以实证的方法阐述惯性系"状态的改变"与"位置的改变"是两个不同的概念，以及我对惯性系"位置的改变"参考系未必能脱离自然客体而独立存在的看法。

Well, the law of inertia says that something in motion will tend to stay in motion, and what's more, to move in a straight line.

惯性定律说，任何处于运动的物体会继续保持运动，而且，会在一条直线上运动。

In this dissertation,the higher order rigid-flexible coupling dynamic model,which isdifferent from the structural dynamics model in the non-inertial reference frame withlarge overall motions known,which takes the coupling between large overall motionsand deformation motion into account with large overall motions being free,and ofcourse which is more accurate than the zero order model,is established for the first time,based on mechanical principles.

本文从力学基本原理出发，针对大范围运动为自由的刚-柔耦合系统，首次建立了较零次近似更精确的高次耦合动力学模型，与大范围运动为已知的非惯性系下的耦合动力学模型不同，进一步考虑了大范围运动和变形运动的相互耦合作用。

The scale analysis on planetary scale motion in the tropical atmosphere shows that the equilibrium between the pressure gradient force and Coriolis force in the meridional direction is easily established, which is known as the zonally semi-geostrophic motion The semi-geostrophic adaptation process in which the inertial gravity waves play an important part is relatively quick The evolution process after the semi-geostrophic adaptation process is slow and controlled by the Kelvin waves and long Rossby waves

对热带大气行星尺度运动所做的尺度分析和物理分析表明：热带大气的行星尺度运动在y方向容易实现气压梯度力与Coriolis力的平衡，它称为纬圈的半地转运动。半地转平衡的建立过程，也就是半地转适应过程相对是很短暂的，它不需要考虑f=β0y随y的变化，因而主要依靠惯性重力波为频散；而半地转平衡建立后的演变过程相对是很缓慢的，它主要受Kelvin波和Rossby波控制。

The shorter of interruption duration, the more obvious interruption effects, and this support the motion opponency theroy. 3 The different intervals between priming and target were detected. Due to interruption of blank frame, the shorter interruption elicited positive proming effects, which is consistant with integration of temporal and spatial in the human brain. 4 The negative of the same direction is relationship to visual adaption and visual inertia effects.

本系列实验得到以下主要结果与结论：1插入空白图片，将导致特定运动方向的反转，而对二义的运动没有明显影响，反映了空白图片对正常视觉运动的阻断；2阻断时间越短，导致特定运动方向反转的几率越大，即阻断效应越明显，支持运动知觉对立理论；3考察不同间隔的启动——靶刺激，由于空白刺激的插入，启动——靶刺激间隔较短时引起的正性启动效应，与人脑系统对视觉信号的时间与空间整合和视觉惯性是一致的。4同向运动的负性倾斜效应与视觉适应有关。

An improved UKF method is proposed and applied to the nonlinear initial alignment of SINS on the stationary base. Simulation results illustrate that the given method has a better performance in the estimation of the azimuth error than the EKF, traditional UKF and scaled SSUKF does. Based on the dynamic error equations of SINS, the mathematics model of the IMU/GPS integrated navigation system is derived for Kalman filtering.

Nonlinear partial differential dynamic equations of bending vibration of a tilting stepped drive shaft with two supports were built under non-inertia movement coordinate system by theorem of the motion of mass center and Heaviside function. According to the condition of equal displacement in an adjoining plane of the shaft, an equivalent shaft and its equation were obtained. A motion equation of the equivalent shaft was obtained by method of Galerkin. An approximate steady-state solution of the main resonance was obtained by method of multiple scales. The influence factors, motion stability, amplitude jump of main resonance of a stepped drive shaft and so on were analyzed.
