 In this paper, we give a quadratic differential system which is the quadratic polynomial perturbation of u = uv, v =1- u~2 -v~2. By discussing we obtain it can bifurcate the limit cycles of type (0, 1), (1, 0), (1, 1), (0, 2), (2, 0), which distinctly answers that quad- ratic differential systems may appear Poincar's bifurcation. 本文给出一个二次系统=uv,=1-u~2-u~2在两次多项式的扰动下,经过讨论获知,可以分叉出(0,1)、(1,0)、(1,1)、(0,2)、(2,0)分布的极限环,从而明确答了二次系统会出现Poincar分叉。 短句来源 In alcohol, using the 3-point quadratic polynomial in the wavelength range 286 to 292 nm at 12 nm intervals, the coefficient of the polynomial, P_2, provides a precise estimate for coenzyme Q_(10) and eliminates the interference from TW-80.

 The velocity of the sheet is a quadratic polynomial of the distance from the slit and the sheet is subjected to a linear mass flux. The interpolant is obtained patching together cubic with quadratic polynomial segments; it is co-monotone and/or co-convex with the data. Cubic-spline and discrete-quadratic polynomial techniques are presented for reliably computing up to third-order derivatives of experimental information. An algorithm to recover bit timing is proposed which maximises a quadratic polynomial approximation to the log-likelihood function. The formulae are characterized by the presence of an infinite series whose general term consists of a linear recurrence damped by the central binomial coefficient and a certain quadratic polynomial. 更多 Lef f(x) be a quadratic polynomial with cocfficients in a finite field F、 On how many points of F can f(x) take values which are squares in F?
