Order to minimize the effect of construction on the public, apart from the active replacement of old pipes, we have also introduced a new method for continuous water supply to be used in particular places, so as to reduce the scope and frequency of water suspension. even though the cost is higher, it can effectively prevent water pollution and reduce water loss during the construction
了降低施工對民眾造成的影響，本處除積極汰換老舊管線外，也引進新的不斷水工法，用在特定場合以縮減停水范圍和次數，雖然成本較高，卻可有效防止水質污染減少施工時所流失的水量。 -
There are three power transistor which have been widely used in s band now : bipolar junction transistor ( bjt ), gaas metal - oxide semiconductor field effect transistor ( gaas mosfet ) and lateral diffuse metal - oxide semiconductor field effect transistor ( ldmos fet ). thanks to the advantages, such as, wide frequency, easy power supply, good stability, the ldmos fet has used in the motion telecommunication
目前在s波段人們常用的放大器有雙極性晶體管（ bjt ） 、砷化鎵場效應晶體管（ gaasmosfet ） 、邊緣擴散場效應晶體管（ ldmosfet ）等，由於ldmosfet具有頻帶寬、供電方便、穩定可靠等優勢，目前已經廣泛用於移動通信3g的研究。 -
Next, mathematical models concerning the bullwhip effect are set up to analyze this effect. models presented here reveal how the lead time, frequency of demand forecast and the price fluctuation affect the bullwhip effect and prove that information sharing can mitigate the bullwhip effect. in addition, a variety of corrective actions are recommended to reduce the bullwhip effect and improve the efficiency of supply chain management
接下來，用定量的方法建立起了相應的數學模型對「長鞭效應」進行了深入分析，揭示了訂貨提前期、企業需求預測頻率的變化以及價格波動對長鞭效應的影響，並且證明了供應鏈的信息共享可以弱化「長鞭效應」 。 -
The features of frequency inversion and speed regulation technology were introduced. its application in water supply project and house construction and energy saving effect were presented
