Qi sentence example

qi
• It also means peace, harmony, serenity and good ch'i or qi.
• Since dp4+(-)P+T1(p +q qi 1)!dd4, the solutions of the partial differential equation d P4 =o are the single bipart forms, omitting s P4, and we have seen that the solutions of p4 = o are those monomial functions in which the part pq is absent.
• Hence Qi /CI =Q2/C2 or Q I /Q 2 =C I /C 2.
• Let qi, q2,..
• If the system is supposed to obey the conservation of energy and to move solely under its own internal forces, the changes in the co-ordinates and momenta can be found from the Hamiltonian equations aE aE qr = 49 - 1 57., gr where q r denotes dg r ldt, &c., and E is the total energy expressed as a function of pi, qi,.
• Thus after a time dt the values of the coordinates and momenta of the small group of systems under consideration will lie within a range such that pi is between pi +pidt and pi +dp,+(pi+ap?dpi) dt „ qi +gidt „ qi+dqi+ (qi +agLdgi) dt, Thus the extension of the range after the interval dt is dp i (i +aidt) dq i (I +?gidt).
• Let us fix our attention on a small area dS of the boundary of the s (3) qi „ and so on.
• We denote these co-ordinates by qi,qi,..
• However slight these forces may be, the total energy T+V must continually diminish so long as the velocities qi,q2,.
• In discussing the small oscillations of a system about a configuration of stable equilibrium it is convenient so to choose the generalized co-ordinates qi, q2,..
