  1. Due to issues of dongting lake districts flood composition, the evolution of sediment flow, the river and lake ( r & l ) distribution characteristic as well as the layout of r & l - dredging engineering, the article simulated the model of the dongting lake terrain change by using the gis technology and adopted the limited volumetric method to establish the two - dimensional hydraulics computation model of lake in order to forecast the water level, the flow capacity, the speed of flow and changes of flow field after implemented the project, which have provided the reliable theoretic basis for the decision - making and implementation of renovation for river course, canal and harbor and river course - dredging engineering

    摘要針對洞庭湖區的洪水組成、水流泥沙演變、河道湖泊水系分佈特點以及河道湖泊疏浚工程布局情況,利用gis技術模擬洞庭湖地形變化,採用有限體積法建立了湖泊二維水力學計算模型預測疏浚工程實施后的水位、流量、流速流場變化,為河道、航道港口整治、河道疏浚清淤等工程決策與實施提供了可靠理論依據。
  2. In addition, there exists 72. 2 % of the chromosome surface positively stained with r - banding. 4. complementarity of g - and r - banding pattern it is generally accepted that chromosome banding patterns appear closely related to differences in dna base composition, and r - bands correspond to gc - rich dna and g - bands to at - rich dna

    4 . g 、 r帶型的互補性一般認為,染色體的帶紋與其堿基組成密切相關, r陽性帶對應于gc含量豐富的區域, g陽性帶則對應于at含量豐富的區域。
  3. Through the test of the separating sieve ' s and beams vibration acceleration, the dynamic bending moment, torque and shearing force as well as the analyze of each parameter by dividing rotation speed range from 300 r / min to 600 r / min of the main shaft, the change regularity of the vibration of the separating sieve, the vibration and the dynamic load on dangerous cross section with the change of rotation speed of the main shaft is obtained. research shows that there exits apparent relevance between the vibration as well as the dynamic load of the main beam and the vibration of the separating sieve. the vibration of the separating sieve mainly affects the composition of low frequency of the vibratio n of the main beam, appropriately amending the vibration acceleration of the separating sieve, the loading and vibration of the mam beam can be directly improved

    通過分檔測試主軸轉速在300 600r min范圍內分離篩與梁的振動加速度、梁所承受的動態彎矩、扭矩和剪力以及各參量的時頻域分析,得到了主軸轉速與分離篩振動、主梁的振動及其危險截面的動態載荷間的變化規律,研究表明梁的振動和其所承受的動載與分離篩的振動之間具有明顯的相關性,分離篩的振動主要影響梁振動的低頻成分,適度改善分離篩的振動加速度,可直接改善梁的負載和振動特性。
  4. In chapter4 - 5, we use factor - analysis to investigate the composition of corporate governance culture and find four factors, that is the safeguard of special capital owner ' s rights and interests ( c factor ), innovation and openness ( i factor ), standard ( s factor ) and social responsibility ( r factor )

    Cisr這四個因子的現實含義分別是有效保障專用資本所有者權益觀念及其制度、創新開放觀念及其制度、規范觀念及其制度以及社會責任觀念及其制度。
