  1. These character based on sichuan power network ' s practice operation experience, in allusion to the config of the carrier wave protection in bypass breaker operating, through the study of protection ' s typical config : one side lfp - 902a, one side csl - 101a, proceeded comprehensive act module test, noted plenty of first hand test data and wave picture, proceeded detailed theory analyses, plenitude demonstration atresic type carrier wave distance protection when twain side atresic type logic is not completely same, basically can fill power network ' s requirement to relay of reliability selectivity speedly and sensitively

    本文結合四川電網的實際運行經驗，針對旁路開關代路運行時的保護配置情況，通過對旁路代路時保護典型配對組合：一側lfp - 902a ，一側csl - 101a的保護配置情況的深入研究，做了全面的動模試驗，記錄了大量的第一手試驗數據和波形，進行了詳細的原理分析，充分驗證了高頻閉鎖式距離零序保護在兩側閉鎖式邏輯不盡一致的情況下，基本能夠滿足電網對繼電保護的可靠性、選擇性、快速性以及靈敏性的要求。
  2. New tracers and their analysis methods, new developments on the interpretation of tracer response and new concepts & methods contributed on tracer methodology. since 1980s, interwell radiotracer test has gained rapid development. the main reasons are radiotracers has the advancetages of high sensitivity, wide selectivity and no chemical contamination on the reservoir

    自上世紀八十年代以來，放射性井間示蹤測試在國際上得到了很大的發展，主要是因為放射性示蹤劑具有種類多、檢測靈敏度高、並且對油藏不產生化學污染等優點。
  3. Mechanical test results must be evaluated in conjunction with catalyst activity, selectivity, and stability data.

    必須將機械測試結果和催化劑活性、選擇性和穩定性數據聯系起來進行綜合評價。
