The user insets the money into the slit, and then the coin recognizer identify the inserted money and add it up; then the MCU sends out the signals about sellable goods by lighting the pilot lamp, so that the user can choose what he or she wants to buy; following the user presses the key related the goods which he or she wants to buy, and then the key makes single chip to start relevant parts to push out the goods, and now the buyer can get the goods. If there still left enough money, the user can buy another goods.

A corneal abrasion with a diameter of 7 mm was created centrally in both eyes with a trephine and subsequent rubbing off on the corneal epithelium with a 20% alcohol soaked swab. Photographic documentation and hematoxylin and eosin stained pathological section were performed when rabbits were killed at 0,12,24,36,48 and 72 h. Planimetry was performed, and the corneal photographs were analyzed with computer software.

The minor principal stress of slab, the maximum acceleration in up-down stream direction and permanent deformation of the dam body for three-directional earthquake excitation are obviously different from those for unidirectional and two-directional earthquake loading.

计算表明，多向地震动下的面板峰值小主应力、顺河向峰值加速度及坝体的永久变形均与单向和双向输入时显著不同，实际工程计算时应同时考虑三个方向的地震动；振动型地震激励引起的坝体反应明显大于冲击型地震激励；随着地震动强度的增加，峰值加速度、峰值剪应变、面板应力和周边缝变形等增加；面板刚度对面板的应力值和周边缝的变位具有较大影响，当面板模量取值较低时，计算所得到的"面板"应力集中部位不甚明显，计算结论为新型的"土工膜面板堆石坝"提供了理论依据。

In Chapter 5, the authors study the convergence properties of the gradient projection method for the constrained optimization problem. In this chapter, a new step-size rule, which avoids fulfiling the classical line search and includes choosing a constant as the step size as a special case, is presented and analyzed.

第五章研究了求解约束最优化问题的梯度投影方法，在步长的选取时采用了一种新的策略，这种策略不需要进行传统的线搜索且包含步长取常数这种特例，在较弱的条件下，证明了梯度投影方法的全局收敛性。

There are many skin folds in human body which are adapted to the need of movementand also the important marks to divide anatomic regions.i.e.the groin is the skin fold whichexists between lower abdomen and anterior thigh,the gluteal-thigh sulcus is skin fold whichexists between buttocks and posterior thigh.Correspondingly,the skin fold which existsbetween pudendum and superior-medial thigh is named pudendal-thigh sulcus,and flapsharvested from pudendal-thigh territories can be called the pudendal-thigh flaps.

人体体表有许多皱褶，这些皱褶是为了适应运动的需要，同时也是解剖学分区的重要体表标志，如存在于下腹部与股前区的皮肤皱襞称为腹股沟，存在于臀部与股后区的皮肤皱襞称为臀沟，相应地，存在于大腿内上方与会阴部之间的皮肤皱褶可称之为阴股沟(pudendal-thigh sulcus)，在阴股沟区切取的皮瓣即称为阴股沟皮瓣(the pudendal-thighflap)。

When parameters satisfy some assumptions, Rossler system is a chaotic dynamical system. In order to discuss the dynamical character of Rossler system and use delayed feedback control chaos, in the first, we discuss the stability of the steady states of Rossler system with delayed feedback. When the engenvalues of the linear part are pure imaginary numbers, we obtain the corresponding delay value. The stability of the steady state is lost when the delay passes through the critical value, and simultaneity chaos may vanish, as well as there will be a family periodic solutions bifurcate from the steady states.

在几个参数满足一定的假设条件下，Rossler系统是一个具有混沌特性的动力系统，为了研究该系统的动力学性质并利用时滞实现混沌控制，本文首先对具有时滞的Rossler系统的平衡点进行稳定性分析，当系统的线性部分对应的特征值为纯虚根时，算出相应的时滞τ，得到了平衡点的稳定性会在时滞τ取某些值时发生翻转，同时系统的混沌特性也会出现变化，并且在平衡点处系统经历Hopf分支。
