微分進化算法DE是1995年由Rainer Storn和Kenneth Price首先提出。DE已被證明在求解過程中具有高效性、收斂性、魯棒性等優點[5,6] 。它在許多優化問題中都表現出優于自適應模擬退火算法、POS 算法、GA算法的性能。DE利用實數值參數向量作為每一代的種群，它的自參考種群繁殖方案與其他優化算法不同。

As environmental concerns over traditional lighting increaseand the Price of LEDs decreases, high power LEDsare fast becoming a popular lighting solution for offl ineapplications. In order to meet the requirements of offl inelighting—such as high power factor, high effi ciency, isolationand TRIAC dimmer compatibility—prior LED driversused many external discrete components, resulting incumbersome solutions. The LT®3799 solves complexity,space and performance problems by integrating all therequired functions for offl ine LED lighting.

基于CC1110單片機公交報站系統主要由CC1110單片機最小系統和WT588D語音模塊組成，提出了如何實現語音報站，通過無線通信SimpliciTI網絡協議實現公交站臺的自動播報和OLCD液晶顯示公交運行的各類信息。結果表明，該公交報站系統報站準確率99%，價格比同類產品下降了300%以上，系統組成結構簡單，提高了系統的抗干擾性和穩定性，也便于攜帶。 Abstract: The bus stop announcement system based on CC1110 MCU is composed of CC1110 MCU minimum system and WT588D voice module. How to achieve the voice announcing is put forward.The bus-stop will announce automatically and display on the OLCD by means of wireless communication SimpliciTI network protocol. As a result， the bus station stop announcement systems reported 99% accuracy rate， Price of similar products declined by 300% or more， system of simple structure， improve the anti-jamming and stability of the power system， it is also portable.

將現行的供暖計費方式由按建筑面積計費變為按消耗的熱能計費是供暖計費方式發展趨勢，為了滿足這一計費方式變化的需要，設計了基于IC卡的預付費式新型供暖計費系統，通過測量用戶采暖系統進出口的溫度和流量，計算用戶消耗的熱能，利用IC卡記錄用戶預付費的金額和當年熱能的單價，根據熱能消耗和當年熱能的單價計算用戶采暖費，根據實際發生的供暖費用和預付費金額控制供暖的開停，這一計費方式的變化使供暖計費更趨合理。 Abstract: It is trend that the mode of heat charging is changed from billing by building area to by thermal energy. In order to meet the needs of heat charging mode changing， a new system of heat charging based on IC card is proposed. The user?蒺s energy consumption is calculated by measuring the user inlet and outlet temperature and flow，using the IC card to record the prepaid amount and the current Price of heat. The user?蒺s heating costs is calculated according to energy consumption and current Price， according to actual heating costs and prepaid amount，the system controls the heating opening or stopping. It is more reasonable that calculated heating costs by user heat consumption
