Elliptical particle acceleration derivation of the expression

1 Lin Jinfu. Such as: particle acceleration expressions derived elliptical l5 ・ 2 acceleration expression Vx: = a - VC0n6 sound ~ luxuriant II: Hi. =- C: Zhen c3 warning = +) J a = (a c0s a sin) + (sin a c0s) (5) b} vii n = sin sound l a ∞ sJ ... a: Pi f + Pi n (7) = In a f + L,[link widoczny dla zalogowanych], where: for the mouth of the tangential acceleration; for the normal acceleration mouth. d ? dt: A (+) da: b (d-r) (2r-r) a (2dr-r2-6) A twins ( Cool

palm: one. bZ (2db2r-r262 a b4) a dr (9) dt = [2i2b2] dt (10) L (2r-r) ~ / 2r-r-J, '. == C0S (11) L children l6 ・ Shanghai University of Engineering Science Volume 16 oosJ9 = N/2d_2r--r-2. -B (12) to (12) generation (11) the results of generations of equation (10), we obtain dt = (2dW2 (13),. A r2, (13) generation method to the acceleration of the expression Port:, available port = / p (14) where ID is the radius of curvature, ID =. 2.3 Conclusion 1) (13) generation (7) the expression acceleration available port: f + ', l ( 15) port = _f XI, l on the j, dtID elliptical motion when the particle acceleration of expression (15) in the radius of curvature | D circular motion to the particle radius R, then the elliptical motion of the particle and particle acceleration expression acceleration of circular motion expression [] the same. 2) angular velocity = d ~ / dt, so (13) is the angular velocity of the particle expression for the elliptical motion. 3) If the particle as the central force field in the elliptical motion, central force field in known conditions,[link widoczny dla zalogowanych], according to equation (13), (15) have the speed, velocity, acceleration and other expressions. 3 applications: dealing with the problem of planetary motion set the focus F2 at the Sun in elliptical,[link widoczny dla zalogowanych], the sun's mass M, planets and the Sun center distance r,[link widoczny dla zalogowanych], the planet can be considered particle, its mass m, acceleration is determined to mouth, mouth in a straight line PF2 on the focus point to the direction F2 (see Figure 1),[link widoczny dla zalogowanych], the GM port where G is the gravitational constant. Shown in Figure 1, normal acceleration and tangential acceleration are fGMI ridicule mouth IGM. 【Canthal 3.1 speed type (2) generation (16) the results of generations (14), may speed (16) (17) 1 Lin Jinfu, et al: Particle Acceleration expression derived elliptical motion 17 ・ IGM/2dr-r2 a b, /-_3.4 angular acceleration angular acceleration of the planet is located n, and n = d. oJ, the type (19) into, have n == Eq (12), (1 Cool

into (11) results into (20), after finishing to get the final n =- GMb (3r-4d) ~ / 2dr-r2-624 Conclusion (20) using this calculation method to solve [3], the physics of planetary motion, obtained for the elliptical planetary motion and angular velocity and other findings have been, and [3] consistent. Thus, this calculation method has some practical significance. References: [1] money tree height, Xia Ying Qi. Hydrogen atoms in the simple disposal of electronic elliptical orbit [J].

(Continued from page 13) Upon examination, B1 transitivity have been met. Thus, the adjustment process is completed, it is that all the requirements of the B. Evaluation of this group's opinion that was (according to the quality of the merits of order) should be: D, A, F, B, E, C. 4 Conclusion How to summarize the basis of individual merit come to a focus on views, Kimura made it can be attributed to linear integer programming problem that requires more computing time, this paper introduces the direct adjustment method to collect the opinions of the management issues A simple and practical method.
