本書以輕松有趣、通俗易懂的漫畫及故事的方式將抽象、復雜的傅里葉知識融會其中,讓人們在看故事的過程中就能完成對數學相關知識的“掃盲”。這是一本實用性很強的圖書,與我們傳統(tǒng)的教科書比較起來,具有幾大突出的特點,一漫畫的形式更易于讓人接受,二邊讀故事邊學知識,輕松且易于記憶,三更能讓讀者明白并記住傅里葉解析問題在現實生活中的應用。本書既可以作為人們日常生活中了解數學知識的讀本,也可以作為數學及相關專業(yè)學生的參考用書,更可以是文科專業(yè)學生理性認識和學習數學知識的工具書及相關專業(yè)的參考用書

VBA是Excel的底層根本。只有明白使用最底層的東西,使用起來才能隨心所欲。對于多數讀者而言,由于未使用過VBA或者不具備計算機語言知識,所以被VBA直白的語句所嚇倒。但是樓主可以肯定的告訴大家,VBA其實很簡單,并且很實用。學會后,也會上癮;變化無窮,很有意思。

The PW4556 series of devices are highly integrated Li-Ion and Li-Pol linear chargers targetedat small capacity battery for portable applications. It is a complete constant-current/ constantvoltage linear charger. No external sense resistor is needed, and no blocking diode is required dueto the internal MOSFET architecture. It can deliver up to 300mA of charge current (using a goodthermal PCB layout) with a final float voltage accuracy of ±1%. The charge voltage is fixed at 4.2V or4.35V, and the charge current can be programmed externally with a single resistor. The chargerfunction has high accuracy current and voltage regulation loops and charge termination

The PW4055 is a complete constant-current /constant-voltage linear charger for single cell lithiumion batteries.Its ThinSOT package and low external component count make the PW4055 ideallysuited for portable applications.Furthermore, the PW4055 is specifically designed to work within USBpower specifications.The PW4055 No external sense resistor is needed, and no blocking diode is required due to theinternal MOSFET architecture.Thermal feedback regulates the charge current to limit the dietemperature during high power operation or high ambient temperature. The charge voltage is fixedat 4.2V, and the charge current can be programmed externally with a single resistor. The PW4055automatically terminates the charge cycle when the charge current drops to 1/10th the programmedvalue after the final float voltage is reached. When the input supply (wall adapter or USB supply) isremoved, the PW4055 automatically enters a low current state, dropping the battery drain currentto less than 2μA. The PW4055 can be put into shutdown mode, reducing the supply current to 25μA.The BAT pin has a 7KV ESD(HBM) capability. Other features include charge current monitor, undervoltage lockout, automatic recharge and a status pin to indicate charge termination and the presenceof an input voltage
