A class of common homogeneous T-S fuzzy systems was constructed using pseudo trapezoid shaped input membership functions, and it was proved to approximate any nonlinear functions satisfying Lipschitz condition to any degree of accuracy. The conclusion relaxes the conservative assumption of previous literatures, therefore, it is more universal.

构造了一类输入变量采用伪梯形隶属函数的一般齐次T-S模糊系统，进而证明了此类T-S模糊系统能够以任意精度逼近满足Lipschitz条件的任意非线性函数，定理假设的保守性得以降低，结论更具一般性。

Methods The epidermal skin around the areola was removed. The skin and tissue of trapezoidal area below breast were removed. The purse-string suture was performed to form a new areola.

方法去除乳晕周围皮肤的表皮，切除乳房下方梯形区域内的皮肤和乳腺组织，再以荷包缝合形成新乳晕，手术后仅在乳房下半留有一条垂直短小瘢痕。

With the application of theory and technology of programmable logic controller -PLC, the control system of transplanting potted seedlings manipulator was developed. First, the hardware of control system for transplanting seedlings manipulator was designed in detail, including the implement components, electrical control components and sensors. Then the design and selection of cylinder, solenoid valve and travel switch, configuration of I/O interface and wiring of PLC were completed and ladder chart and repertoire were drawn up.
