  3. Based upon the analysis of the data obtained during the survey, it can be concluded that : 1 ) the number of biomass of macrobenthos in the yellow sea and the east china sea in autuma is higher than that in spring, while the number of density of macrobenthos in autumn is lower than that in spring ; 2 ) the number of biomass of macrobenthos in the yellow sea is higher than that in the east china sea ; 3 ) the number of species in the yellow sea is lower than that in the east china sea ; 4 ) one of the characteristics of distribution of macrobenthos in the east china sea is that the species richness increased from the coastal waters to the offshore deep waters, from the north to the south. 5 ) the species composition in the deeper part occupied by the cold water mass of the yellow sea is more stable than that in the coastal part of the yellow sea in the late 40 ~ 50 years

    通過以上幾方面的分析，結果表明： 1 ）黃東海調查海域的秋季總生物量均高於春季，總棲息密度則低於早春季； 2 ）黃東海春季生物多樣性指數高於秋季； 3 ）南黃海、東海的水文特點顯著不同：東海底溫顯著高於南黃海底溫，東海底鹽亦高於南黃海底鹽； 4 ）南黃海春秋季生物量分佈無一致規律，東海春秋季生物量除長江口外基本上自近岸向外海逐步降低； 5 ）東海大陸架大型底棲動物的種類組成較南黃海更豐富； 6 ）東海大型底棲動物的分佈特點之一為：種類數由北向南、由近岸（西部）向外海（東部）逐漸增多； 7 ）在黃海冷水團控制的海域，其底棲動物種類組成較近岸海域穩定； 8 ）幾個生物多樣性指數各有側重，都能較好地反映底棲動物的分佈特點

  9. Lt is obvious that the decaying rule of average reverberation intensity is affected by scattering coefficient of sea floor, sound speed profile, inclination of bottom etc. the sea floor scattering function is the most importan factor to the intensity decaying rule

    結果表明：海底散射方向性指數因子、海水聲速梯度、海底傾斜角等對海洋混響平均強度的衰減皆有影響。海底散射方向性指數因子對其影響最大，即適當選取海底散射模型是淺海近程混響建模的首要因素。
  10. Several influence factors to result plasma drift in hainan were analyzed. in this paper the characteristics of ionospheric parameters variation were analyzed systematically and some new results in storm - time such as seasonal behaviors were obtained ; it is the first time to investigate the ionospheric drift behavior in hainan and some new results was obtained, the relationships between each two plasma drift velocity components in storm time in hainan were found and the electric filed variation in hainan ionosphere also was obtained ; the results also show that there are big differences of the ionosphere parameters bo and bl obtained from the data with that obtained from the iri - 2001 applied for hainan ; a new phenomena was found during a strong magnetic storm, that a layer with very strong electron density and density grad was found during the recovery phase of the storm, its horizontal scale is beyond 100km and temporal scale is about 2 hours, this phenomena repeated 3 times continuously. a type of negative disturbance in high and low latitude but positive disturbance in east - asia also has been found

    本文較為系統地給出了海南地區電離層的參數變化特徵，特別是得到了一些暴時與以往不同的季節特性；第一次給出了海南地區的電離層等離子體漂移特徵，發現等離子體漂移暴時擾動在三個方向上有內在的聯系，得到了電場變化曲線；研究結果還表明海南電離層的半厚指數和形狀參數等與國際參考電離層iri - 2001存在很大差別；通過對強磁擾動事件期間的參數變化特性分析發現，在磁暴恢復相期間海南地區電離層底部存在一個電子密度非常大的高密度區，高密度區底部電子密度梯度隨高度急劇增加，該區域的水平尺度可達100公里以上時間尺度約為2小時，連續出現過三次，這是一個在海南從來未發現的新現象；研究還發現了暴時東亞地區電離層擾動會出現高低緯負相而中緯正相的現象。
