With straton - chu intergral as the theoretical basis and by means of green ' s function in infinite uniform media, the electromagnetic shift describes the propagation process of quasi - stationary electromagnetic field in lower - half space
電磁偏移以斯特萊頓朱型積分為理論基礎，藉助于無限均勻介質中的格林函數，描述了似穩電磁場在下半空間的傳播過程。 -
It use a psc to replace the switch, and implement the csma / cd in the network interface card ( nic ). when the throughput grows and transfer speed is raised, csma / cd will lower the network ' s performance, but think about such truths below, the half - duplex gigabit optic ethernet will have some market space. first, there still exist large amount of small - size local network nowadays ; but they require high transmit speed, such as studio, lab etc, especially multimedia, graph and image processing, virtual reality and advertising
但是，在目前情況下，出於以下幾個方面的考慮，使用csma cd方式的半雙工千兆位網路也有它的發展空間：第一、在目前的情況下，有大量的小型局域網存在；但是又要求高的傳輸速率，如工作室、實驗室等工作組級的網路，尤其是現在十分常見的多媒體應用、圖形圖像處理、虛擬現實與廣告渲染等方面。
