A space solar cell bonding robot system which consists of a three-axis Cartesian coordinate's robot, coating device, bonding device, orientation plate, and control subsystem was studied.
For use in cosmogonical investigations,a detailed calculation of the angular momenta of various bodies in the solar system is made,making use of latest data. A_(1P) denotes the orbital angular momentum of a planet about the center of mass of the sun- planet system,A_(1⊙) denotes the orbital angular momentum of the sun about the same center of mass.A_(1P)+A_(1⊙)=A_1.These three quantities are calculated according to formulae (2),(3),(4), and the results are given in Table 1.In this table A_(1P) include...
It has been shown by S. A. Zhevakin that the critical double ionizarion zone of helium Hell in the envelope of a pulsating star, such as RR Lyrae, is a mechanism giving rise to the auto-oscillation of the star. The mass of the star should have such a value that its Hell zone has a definite non-adiabatic degree of oscillation, so as to excite its auto-oscillation. In the present paper the mass of RR Lyrae is determined on the basis of Zhevakin's theory of stellar variability.The mass of RR Lyrae is first ass...
We treat the problem of solar activity in the long run.The data used include the semi-empirical maxima and minima since 1610 A.D.The method differs from the traditional sun-spot statistics in the following respects: 1.A time-spot number curve using alternative positive and negative smoothed monthly mean number (R) in succesive 11-year cycles is used to take the magnetic property of each cycle into account.This curve is shown in Fig.1(B) as compared to the traditional curve 1(A). 2.A number term...
