本系统以Buck降压和Boost升压拓扑结构开关电源变换电路为核心，以超低功耗单片机MSP430F1222为主控器，由单片机产生PWM脉宽调制信号，分别控制两路电压变换电路中开关管的导通与关断从而实现以上两种拓扑结构开关电源变换电路，进而从一直流电源中吸取电能充入可充电电池，并利用单片机A/D对输入电压实施监测，根据输入电压切换升降压电路，以较低的成本实现了高效率的电能转移，并且电路简单、参数确定容易，自身功耗低，实现功能完整。

Then we had the famous Buck's beaming-at Buck's restaurant in Woodside, which is sort of the home away from home for many VCs.

接着我们得到了著名的Buck's关注--在Woodside的Buck's饭店，它没有和其他风险投资者的家有些距离。

The results indicate:(1) The buck has some behaviors in mating season, for instance, anogenital sniffing, raking the soil etc. Its bedding and conflict interaction is different, and its anogenital sniffing is different remarkably for buck and does.

研究结果表明：(1)在交配季节，雄狍具有卷唇嗅闻、扒土等行为；雄狍与雌狍的卧息、冲突行为差异显著，尾阴探究差异极显著。

And a series of new control type soft switching topologies, such as Buck, Boost, Buck-boost, Cuk, Zeta, Sepic, Flyback, and Forward are constructed by using the theory of five characteristics.

With the capability to be configured in a Buck, Boost, Buck-Boost, or SEPIC topology, and an input and output operating voltage rating of 75V, the LM3429 is ideal for illuminating LEDs in a very diverse, large family of applications.

NS 公司的LM3429是多用途高压 LED驱动器控制器，可以配置成降压，升压，升/降压或SEPIC拓扑，输入和输出的工作电压额定值为75V，内部的PWM控制器可调开关频率高达2MHz。

The MAX15054 enables designers to avoid the cost and complexity of a SEPIC topology by allowing the implementation of buck and single-inductor buck-boost topologies with the output referenced to ground in single string and multistring LED drivers.

MAX15054在单串和多串LED驱动器中通过使用降压以及单电感升降压拓扑结构，并将地电位作为输出电压的参考点，从而使设计人员避免了采用SEPIC结构带来的成本和设计复杂度。

This was a great relief, and Buck caused even the weazened face of Perrault to twist itself into a grin one morning, when Francois forgot the moccasins and Buck lay on his back, his four feet waving appealingly in the air, and refused to budge without them.

这大大减轻了痛苦，以致于一天早上福楼沙忘了给他穿鞋，巴克便仰面躺着不肯走路，四只脚恳求地在空中乱舞，后来他的脚坚硬得适应旅程了，穿破的鞋套也就扔掉了。

Buck had seen harnesses on horses, and now he was made to work like a horse with Spitz and Dave, who had worked in a harness before, and Buck learnt by watching them.

与斯皮兹和戴夫一起干；它们俩以前倒是身套缰绳干过活儿来着。

And more those who make a person accident is, it is almost all and OK that quick buck was offerred for consumer the disbursement of bring into contact with terminal, phone, mobile phone, Internet, email, credit card, outside card, special pay a passageway, leave disbursement customer to be used to a line, quick buck provided a variety of medium of communication such as bank bar, postal bar, credit agency bar.

而更让人意外的是，快钱为消费者提供了几乎所有可以接触到的支付终端，电话、手机、互联网、电子邮箱、信用卡、外卡、专用支付通道，对于习惯线下支付的消费者，快钱则提供了银行柜台、邮政柜台、信用社柜台等多种渠道。

Also, the dog-driver rubbed Buck's feet for half an hour each night after supper, and sacrificed the tops of his own moccasins to make four moccasins for Buck.

而且每次吃饭后，这位赶狗者都要为巴克搓半小时的脚，还用自己的鹿皮靴靴统给他做了四只鞋。

Must have Coordination and negotiation skill, flexible ideas, and be punctilious person.

必须具备较好的协调与谈判能力，头脑灵活，工作认真仔细

Result: 18 patients are all with simple eye.The pigment mole lies in nasal and temple sides of the ball conjunctiva,in which 2 lie in lacrimal caruncle and semilunar plica.

结果：18例患者均为单眼，色素痣大多数位于内外侧睑裂部球结膜面，2例位于泪阜及半月皱襞，经激光治疗后，10例色素痣消失，有5例行再次激光后消失，2例行第三次激光后消失，1例第四次激光后消失。
