Optical code division multiple access ( ocdma ) is a communication mode which introduces the code division multiple access ( cdma ) technology into optical fiber communication system. besides providing asynchronous communications access, ocdma system has many advantages, such as high capacity, security against interception, suppression of narrow band disturbances, capability in forming variable bit rate networks and multi - rate networks. it implies a great challenge for the development of future communication networks, especially all optical networks
光碼分多址( ocdma )是將碼分多址( cdma )技術與大容量的光纖通信技術相結合的一種通信方式,其主要優點表現在如下幾個方面:允許多個用戶隨機地接入同一通道:可構成真正「透明」的全光通信網路;具有良好的安全性;允許可變速率或多速率傳輸,並可同時提供多種業務支持;具有優良好的抗干擾能力,並能夠充分地利用石英光纖的可用帶寬。Compared with common methods for measuring the photosynthesis rate based on consumption of co2, the technique in this thesis can be used to quantify the plant photosynthesis capability with less interferences of the environment. we thus conclude that df is an excellent indicator for evaluating plant photosynthesis ability under its biological status
研究結果表明:植物葉片延遲熒光強度和現有的便攜式光合速率測定儀在實驗室條件下測得的光合速率具有很好的相關性,能較真實的反映植物在所處生理條件下的光合能力。
