  1. It has been proven that the differences of magnitude and distribution of tidal currents, wave energy rate, suspended sediment concentration and the stokes number result in a asymmetrical distribution of sandbanks between the north and south. the sandbank surface area and length in the north are lager than those in the south, but its cross section area is less than that in the north

    各種動力特徵平面分佈規律研究表明，輻射沙脊群南北沙脊不對稱分佈的格局是潮流沙脊對潮流往復流性質的強弱分佈、潮波能流率大小分佈、含沙量的平面分佈規律及斯托克斯數的大小分佈的動力響應。
  2. In the first step. 2861 surface wave recordings with seismic magnitude over 5. 0 are selected under the criteria of good - wave and " intact recording ", calculating the big - circle paths, and then about 284 two - station pairs of which two stations are along the same big - circle are chosen, among them there are about 260 pairs with difference of forward azimuth angle less than 5 ?. after further optimizing, 223 pairs which perfectly cover the china area are used in the final calculation

    本文首先從所收集的震級在5級以上2861條面波記錄中挑選波形好、記錄完整的資料進行預處理，計算其大園路徑，從中挑選出位於同一地震大園路徑上的雙臺地震記錄約284對，然後計算出前向方位角差，其差在5范圍以內的雙臺地震記錄約260餘對，量后對這些記錄進一步優化，選出223對對中國大陸地區覆蓋比較好的面波記錄。
