proof mass 中文意思是什麼
proof mass
解釋
檢測質量-
Though the researchers have no direct proof that the new planet is rocky, its mass means it is not a giant gas planet like jupiter, they said
盡管目前研究人員還沒有直接證據證明這是一顆巖狀行星，但是他們宣稱，這顆行星的質量表明，它並不是一顆類似木星的巨大氣體行星。 -
The ids works by two way, misuse detection and anomaly detection, misuse detection flags an intrusion on intrusion signature, this kind of detecting technic can be realized much more easily, and much more accurate, but it can not find some intrusiones that have been disguised or new kinds of intrusion. the anomaly detection can detect in more wide field, anomaly detection can compare new statistic data with average record, then anomaly record will be found, but it ' s more difficult to set a threshold, if the threshold is too big, some intrusion may be put through, if the threshold is too small, the ids will give more false positive alarm, and the threshold will be different with different people or different period, so the ids just simply show us their suspicious record, the administrator or expert will be in duty to analyze this record and give conclusion, the ids give more alarm than it should, leave us more detection record to analyze, and this is a hard work, we can not distinguish an intrusion or not if we analyze only one record, but we can judge if we find the relation among mass detection evidence. in this article, we try distinguish an intrusion using d - s theory ( proof theory ) instead using manual work, the ids will be more helpful and efficient
濫用檢測採用的是特徵檢測的方法，實現較為簡單，判斷的準確性較高，但是不能判斷一些經過偽裝的入侵或特徵庫中尚未包含的入侵，異常檢測能夠根據以往記錄的特徵平均值，判斷出異常情況，但是對于異常到什麼程度才視為入侵，這個閥值非常難以確定，閥值設定的太高，有可能漏過真正的入侵，如果設定的閥值太低，又會產生較高的誤警率，而且這個閥值因人而異，因時而異，因此現在的入侵檢測系統把這部分異常記錄以一定的形式顯示出來或通知管理人員，交給管理人員去判斷，而這些ids系統難以判斷的記錄，如果對每個證據單獨地進行觀察，可能是難以判斷是否是入侵，而把許多先後證據關聯起來，專家或管理人員根據經驗能夠判斷訪問的合法性，本文試圖引入人工智慧中證據理論的推理策略和示例學習方法，代替人工檢查分析，可以提高效率，降低誤警率，並可以對一個正在進行得可疑訪問實現實時檢測，通過搜索及時判斷，及時阻斷非法訪問，比事後得人工處理更有意義。 -
After numerous painstaki ng analysis and proof, i " ve got the following conclusion : competition pressure and relative payment are the two key factors whose inter relationship determines the working motivation of differ. errt mass teachers
通過對大量的實際材料的分析和論證，本研究得出以下結論：競爭壓力和相對報酬之間的相互關系是決定不同教師群體工作積極性大小的兩個關鍵因素。 -
The traditional designs of inertial sensors involve a solid proof mass or rotation part, which have some disadvantages such as low life, low reliability, difficult manufacturing and high cost
目前商用的慣性傳感器一般需要檢驗質量塊或者旋轉部件，因此，器件的壽命短、可靠性低、加工困難且成本較高。
