Using three - dimensional tomographic imaging results of 2 ? 2 ? grid s wave velocity and 15 ' 15 ' grid average gravity anomaly in north china, this paper adopted inversion with constrained least squares method and, as a result, obtained density distribution results of six bedding surfaces in lithosphere of north china
摘要利用華北地區的2 ? 2 ?網格s波速度三維層析成像結果和15 ? 15 ?的網格平均布格重力異常，採用約束最小二乘方法反演，得到了華北地區巖石圈內6個層面上的密度分佈結果。 -
For solving the problems that downward continuation of the space gravity anomaly can not be used in downward continuation of sea surface gravity anomaly, on the basis of prey principle used to compute gravity in the surface - layer of the earth, and with considering the density of sea water and sea bottom topography, two new methods are proposed
摘要針對空間重力異常向下延拓方法不適用於海面重力異常向下延拓的問題，根據珀雷原理求地球表層內部重力的方法、海水密度及海底地形的特徵，提出了兩種海面重力異常向下延拓的演算法。 -
It is often impossible to differentiate between structure and density contrast in determining the source of a gravity anomaly.
在確定重力異常源時，不可能在構造與密度差之間作出抉擇。 -
Normal behavior and anomaly are distinguished on the basis of observed datum such as network flows and audit records of host. when a training sample set is unlabelled and unbalanced, attack detection is treated as outlier detection or density estimation of samples and one - class svm of hypersphere can be utilized to solve it. when a training sample set is labelled and unbalanced so that the class with small size will reach a much high error rate of classification, a weighted svm algorithm, i
針對訓練樣本是未標定的不均衡數據集的情況，把攻擊檢測問題視為一個孤立點發現或樣本密度估計問題，採用了超球面上的one - classsvm演算法來處理這類問題;針對有標定的不均衡數據集對于數目較少的那類樣本分類錯誤率較高的情況，引入了加權svm演算法-雙v - svm演算法來進行異常檢測;進一步，基於1998darpa入侵檢測評估數據源，把兩分類svm演算法推廣至多分類svm演算法，並做了多分類svm演算法性能比較實驗。 -

摘要依據巖石密度特徵，應用布格重力異常資料，在內蒙古東部地區推斷7個大型巖漿巖活動區（帶） 。 -
According to the types of rock density and magnetism of magmatite, with separation, continuation, derivation, and false color encoding between gravity anomaly and magnetic anomaly as well as a composite process of their attributive information, the magmatite belts reflected by both gravity anomaly and magnetic anomaly can be divided into two belts and seven group sections based on their positions in the tectonic unit, the magma series characteristics, and the time - space relationship with the ore belt
摘要根據不同類型巖漿巖的巖石密度、磁性的不同，通過重磁異常分離、延拓、求導、異常的彩色編碼及重、磁特徵信息的復合處理等，按重磁反映的巖漿巖帶所處的構造單元部位、巖漿系列特徵以及與礦帶的時空關系，將秦嶺造山帶劃分為2帶和7個群段。 -
