Whether the solution f vanishes at z = 0 or not plays a critical role for local analytic solutions of this equation. In this paper, we obtain results of analytic solutions not only in the case f（0） = 0 but also for f（0） ≠ 0. When assuming f（0） = 0, for technical reasons, we just get the result for f′（0）≠ 0. Then when assuming f（0） = ω0 ≠ 0, ψ（0） = s # 0, ψ（z） is analytic at z = 0 and ψ（z） is analytic at z = ω0, we give the existence of local analytic solutions f in the case of 0 〈 ｜sω0｜ 〈 1 and the case of ｜sω0｜ = 1 with the Brjuno condition.展开更多

The purpose of this paper is to determine the use of metacognitive strategies in reading by the PE & Art majors through questionnaire. According to the result of the questionnaire, the PE & Art majors do use some metacognitive strategies in their reading, while nearly half of them do not often use metacognitive strategies in their reading. For this phenomenon, the author gives some constructive suggestions for the English majors about how to apply the metacognitive strategies in their reading: 1) preparing and planning in pre-reading; 2) monitoring and self-questioning in while-reading; 3) evaluating and adjusting in post-reading.展开更多

The key idea is to decompose the design problem into two simpler design steps by the technique used in the classical loop transfer recovery method （LTR）. The disturbance cancellation integral controller is used as a basic controller. Since the standard loop transfer recovery method cannot be applied to the disturbance cancellation controller, the nonstandard version recently found is used for the decomposition. Exogenous inputs with constraints both on the amplitude and rate of change are considered. The majorant approach is taken to obtain the analytical sufficient matching conditions. A numerical design example is presented to illustrate the effiectiveness of the proposed design.展开更多
