 This increase does not appear to be due to a failure of the proteins to assemble into the proper fraction. A situation is even more complicated in the not-discussed case of regression, where the proper fraction can depend on some known vector of covariates. We shall attempt to study an interesting phenomenon in the theory of best approximation. We begin by some concepts which will be used below. 1. Let be a Hilbert space, h_n∈, and let (h_,h_k)=η_r),n,k=0,1,2,...; (1) (ⅰ) If η_(nk)=1 (n=0,1,2…), (2) η_(nk)→0 (for n≠k, as n,k→∞) (3) and η_(nk)→0 (for any fixed k, as n→∞; for any fixed n, as k→∞),(4) then we say that the sequence {h_n} is a quasi-orthonormal system (QONS)of 1st kind. (ⅱ) If (2) and (4) are satisfied, we say that {h_n} is a QONS of 2nd klnd. (ⅲ) If... We shall attempt to study an interesting phenomenon in the theory of best approximation.

Let be a Hilbert space, h_n∈, and let (h_,h_k)=η_r),n,k=0,1,2,...; (1) (ⅰ) If η_(nk)=1 (n=0,1,2…), (2) η_(nk)→0 (for n≠k, as n,k→∞) (3) and η_(nk)→0 (for any fixed k, as n→∞; for any fixed n, as k→∞),(4) then we say that the sequence {h_n} is a quasi-orthonormal system (QONS)of 1st kind. (ⅱ) If (2) and (4) are satisfied, we say that {h_n} is a QONS of 2nd klnd. (ⅲ) If (2) and (3) are satisfied, we say that {h_m} is a QONS of 3rd kind. 2. Let f(x)∈C_(-1,1), p(x)∈C_(-1,1) be a non-negative weight function, and let P_n(x)=P_n(f,x) be the (nth) best approximation polynomials or simply the minimum polynomials of f with the weight p on [—1,1. We say simply that ψ_n(x)=f(x)-p_m(x) is the minimum sequence of functions for f. 3. Let f∈C_(-1,1)~′ (the class of functions with 1st derivative belonging to C_(-1,1), L_n=‖(f—P_n)p‖y_n=(f—P_n)P, where P_n are the minimum polynomials, the functions Q_n(x)=(y_n~(′2))/(L_n~2-y_n~2) (5) are called the (nth) associate functions of f. Concerning these definitions and reserving the sense of the above symbols, we proved the following theorems. Let A be a certain class of real irreducible proper fractions and let the positive weight p(x) take the form Ⅰ. {C_0+…+c_vx~v}~(1/2) or Ⅱ. {C_0+…+c_vx~v}~(-1/2); Then under certain restrictions (see the begInning of §2) we have THEOREM 1. Let R_n(x)={Q_m(x)((1-x~2)/((n±v/2)~2))}~(-1) where="±" corespond to p taking Ⅰ or Ⅱ, respectively. (ⅰ) If L_m=O(1),‖1—R_m‖=o(1/n), ‖R_n~′‖=o(1/n), then the normal minimum sequence of functions λ_n {f—P_n} is a QONS of 1st kind in space L_(-1,1)~2((p~2(x)/(1-x~2)~(1/2)) (ⅱ) If L_m=o(1),‖1—R_m‖=O(1/n), ‖R_n~′‖=O(1/n), the conclusion of (ⅰ) also holds. (ⅲ) If L_m=O(1), ‖1—R_n‖=o(1), ‖R_n~′‖=o(1), the same sequence λ_n{f—P_n} is a QONS of 2nd kind in L_(-1,1)~2((p~2(x)/(1-x~2)~(1/2)). THEOREM 2. Let p(x) be of the form Ⅱ, the associate functions of f be of the form Q_n(x)=((n-v/2)~2)/(1-x~2){1+sum from n=1 to 1,μ B_l/(x-β_l)+sum from n=1 to 1,v C_j/(x-y)}~2 (U_(μ-1)~2)/(V_(2μ-2)), where B,C,β,γ are constants, U,V are some μ—1 th and 2μ—2 th order polynomials, respectively. If (ⅰ) (?) (U_(μ-1)~2(x))/(V_(2μ-2)(x))=1 (—∞ 文中引进伪直交性(quasi-orthogonality)概念,它是平常直交性概念的一种推广。受到了古典切彼曉夫多項式等的提示,我們指出对於連續函数的某一子类,其最小元列在某內积空間中具有第一种、第二种或第三种伪直交性。这些結果可以看成一种嵌入性质(embedding property)。文中有若干例子說明伪直交系的存在,还給出定理的特例,即在某些情形最小元列具有(真)直交性。 This article defined constant in numerator of simplest fraction by the way of resolve proper fraction to simplest fraction. 本文用分解真分式为最简分式的分解基本定理来确定最简分式分子里的常数。 This paper briefly describes the study on the formulation of series DABreciprocal compressor oil from proper fractions of the Xinjiang low-sulfurintermediate base crude with packaging of appropriate anti-oxidant, antico-rrosion agent and antirust additive.
