In this paper,the method of discrete motion of multinominal subsection fiting the driven(member) of cam mechanism has been diccussed and the design calculation and analysis of cam mechanism after discrete(motion) successively.

Using variable-separating method,it separates time variable from space variable,and Galerkin equation of discrete motion is used in discussion on the change trend of stable zone of the transition curve. And the numerical solution of the equation of motion is obtained using 4-order Runge-Kutta method. Furthermore,the effect of material properties of warp yarn and various parameters on the crosswise motion of the yarn is investigated,and the method to control the vibration of warp yarn is given.

Hence, it is the important topics of modern dynamical systems to study the continuous motion described by differential equations and to study the discrete dynamical systems described by iteration of mappings.

Next, the author studies the connection of first integrals with particular solutions of the nonsimultaneous variational equations for nonholonomic systems, and presents a new approach to find the inverse problem of Lie symmetry for nonholonomic systems.

(4) The poloidal convection patterns in the uppermost mantle have good correlations with global surface plate motions. We can interpret the divergent or convergent motive state of the plates close to large tectonic zones and then recognize and understand their formation in deep dynamics by our computed poloidal field.

It is a new-style method of the drive control fed by static transducer in the control of the microcomputer, which makes the stator flux movement discrete. And position and speed outputs can be achieved on the motor axes.

The transition is caused by the flip of the average polarization of one of the interface layers, and can then be described as a bounded discrete motion of the wall separating positive and negative microdomains within the five-fold unit cell.

In the present paper, we propose a change in the representation of the discrete motion equations in structural non-linear dynamics to obtain an improvement in the stability of time numerical integrations.

The theory is developed for both continuous and discrete motion, known and unknown orientation, calibrated and uncalibrated, perspective, weak perspective and orthographic cameras.

The first is based on discrete motion, as typically used in self-calibration algorithms.

The method combines discrete motion estimation and the optical flow estimation in a robust energy minimization framework.

Motion is the essential property of space and time. The unique uniform velocity of photons suggests a pictrue of discrete space-time, since uniformity in motion is a direct property of discreteness. Starting from this point, we discribe the motion of photons by equation (6). We succeed in proving that the motion of photons under its own force field is damped. This damping is caused by the decay of photon energy as a result of action of the own force field. Hence we obtain the well known Hubble formula (11)....

The Nanxiang (Nanyang-Xiangfan) Basin is a fault-subsided petroliferousbasin of the Meso-Cenozoic. It covers an area of about 17000 km~2 with morethan 9000 m thick Meso-Cenozoic sediments. The Hetaoyuan Formation of theLower Tertiary which reaches 3000m in thickness is the main source and reser-voir beds. Up to now, seven oil fields have been found in this basin. The basin can be divided into three depressions. i.e. the Miyang, Nanyangand Xiangyang-Zaoyang Depressions, and four uplifts such as Xinye, Tanghe,Shigang...

The Nanxiang (Nanyang-Xiangfan) Basin is a fault-subsided petroliferousbasin of the Meso-Cenozoic. It covers an area of about 17000 km~2 with morethan 9000 m thick Meso-Cenozoic sediments. The Hetaoyuan Formation of theLower Tertiary which reaches 3000m in thickness is the main source and reser-voir beds. Up to now, seven oil fields have been found in this basin. The basin can be divided into three depressions. i.e. the Miyang, Nanyangand Xiangyang-Zaoyang Depressions, and four uplifts such as Xinye, Tanghe,Shigang and Sheqi Uplifts. The Miyang Depression abounds in oil and gas,the Nanyang Depression is secondary, and yet no oil show has been found inthe Xiangyang-Zaoyang Depression. The traps in the basin are mainly various noses. Eighty four percent of theproved reserves is in the nose traps. The basement of the basin is the Qinling folded belt and the Yangzi Platform.A series of NW compressed and compresso-shear faults developed on the Pre- Mesozoic basement. From late Yenshan to early Himalayan movements, the NWfaults reactivated and underwent sinistral displacement due to tLe closure ofTethys and the collision of the Indian Plate with the Chinese continent. At thesame time, Tanlu fault zone moved in dextral displacement thus resultingthe dextral motion of the NE faults. The motion strength of both NW and NEfaults gradually increased. and fan-shaped fault blocks between them weremade to move divergently, leading to the formation of the fan-shaped faultdepressions. The tension made the crust thinner and the upper mantle uplifted.This in turn accelarated the subsidence of the crust. During the Late Tertiary,the mantle temperature dropped down gradually, elastic rebound and isostarychanged the seperated. subsided basin into an unified depression.

In this paper, a method to determine the radial track of a moving object in HF backscat-ter study is given. In the method, the minimum time delay curve, the time delay of the signal and the Doppler frequency shift of the moving object are sufficient. There is no need to know the ionospheric characteristics of the middle point. A comparison of the calculated data with experiments is discussed and the possible application of the method is also presented.
