2. it simplified the tlp as vertical floating arrays, did some work about second - order nonlinear diffraction wave force on tlp
2 .將結構簡化為直立浮筒柱群，研究了平臺本體上波浪的二階非線性繞射問題。A rare kind of primary round columnar joints is developed in the basic dyke swarms in the western shandongwhich is made of the radial joints and the round columnar joints with same axis vertical to the strike of the dyke, arranged one by one along the strike of the dyke
在魯西地區前寒武紀基性巖墻群內發育一種罕見的原生圓柱狀節理，由同軸圓柱狀節理和放射狀節理組成，垂直於巖墻走向，沿巖墻走向排列，是一種指示巖漿水平侵位的流動構造。With the increase of variance, the difference in h - polarized or v - polarized incident wave and in the different mean cross sections is becoming gradually small until when the variance is infinity namely the rotatory axes of the group are uniformly oriented : at this time the different mean cross sections are independent of the polarized status of incident wave
隨著方差的增大，入射波水平偏振和垂直偏振時的各平均截面的差異逐漸減小，減小到直至方差為無窮大時，即與粒子群取向的均勻分佈的情況相同，此時各平均截面與入射波的偏振狀態無關。The author carried out a comprehensive analysis and study on the competitive characteristics of shanghai in previous nationals games, and revealed the following findings : in the competition in the 5 ( superscript th ) to 10 ( superscript th ) national games, shanghai was able to exert its competitive strength steadily in the event groups of speed and power, accuracy, difficulty and beauty, and grapple ; while the change of its competitive strength in the event groups of speed, net involved competition, same court competition, and endurance, had directly affected the change of its position ; in addition, it is hopeful for events such as weight lifting, boating, shooting, table tennis and water ballet to become a new group of winning events of shanghai in national games
摘要對上海在歷屆全運上競技運動特徵進行分析，結果顯示：在5 ~ 10屆全運會比賽上，速度力量性項群、準確類、難美類和格鬥對抗性項群能穩定地發揮其競技實力，而速度、隔網對抗、同場對抗與耐力類項群競技實力的變化直接影響到名次的變遷；舉重、劃船、射擊、乒乓球、花樣游泳等項目有望成為上海全運會新一輪的制勝項目。Only few analog tv channels are there in country areas and what more the covering range of the analog transmitters is smaller than that of digital transmitters which though with the same power, which result in that the covering site of broadcasting signals is always the urban areas while people who live in the remote areas receive no tv program signals, and as the essential parts of utilities for our party and governments to expressing its administration conception, broadcasting in suburban areas by far cannot give the government the ability to give publicity to the people effectively
農村廣播電視的覆蓋工作，長期以來一直是我們廣播事業建設的薄弱環節。模擬電視節目套數很少，而且同等功率的模擬發射機覆蓋范圍也相對數字發射機的小，通常只是集中覆蓋主要城鎮和人口聚集地，偏遠地區的廣大群眾長期不能收看電視。廣播電視作為黨和政府喉舌的功能，沒有得以充分發揮。By driving expressions and using the method in numerical integration, the results of numerical calculations are analyzed, discussed and contrasted with different conditions, and they showed that there are evident differences in the mean attenuation, scattering, and back scattering cross sections of oblate spheroid particles when the variance is so small that it is near to zero namely it is the same as the rotatory axes are parallel with one direction and when h - polarized and v - polarized incident waves happened. these differences are depended on the relative differences in the average orientation of rotatory axes and the polarized directions of incident wave
通過公式推導和數值積分計算並對結果做了討論和分析，對比各種情況表明：扁橢球粒子群在方差很小接近為0時，與粒子群旋轉軸一致取向的情況相同，入射波水平極化和垂直極化時的平均衰減截面、平均散射截面、平均後向散射截面有明顯的不同，這決定於旋轉軸平均取向和入射波極化方向的相對差異。Date integration technique was used to analyze the relationship between monthly mean daily clearness index kt and s, the ration of monthly mean daily sunshine duration to possible sunshine duration as well as that of monthly mean daily direct transmittance kb. based on data from 1957 to 2000, a series of kt and kb estimation models with different temporal and spatial scales were established. furthermore, the distributions of kt and kb from january to december in chongqing were mapped by kriging interpolation for long - term mean
大氣輻射過程模擬通過晴空指數、直接透射率等綜合描述大氣對太陽輻射影響的參數，採用重慶市及其周邊地區1957 - 2000年日射站觀測的月輻射資料和常規月氣象觀測資料，利用數據集群技術，建立了不同時空尺度的太陽輻射估算模式；使用kriging插值法，完成了重慶市氣候平均狀況下各月晴空指數、直接透射率的空間制圖。In addition, by constructing homomorphisms we obtain structures on semidirect products same or similar to semigroups
