在設計新一代移動通信基站天線時，應使天線能綜合各種分集方式進行天線分集以消除多徑效應，具有波束下傾以減少同頻干擾，能波束賦形以實現優化覆蓋。It has been proved that this kind of tank is applicable of multifold boats, which not only reduces the roll angle and the heel angle, but also improves the efficient and fall the transport cost. the controlled passively anti - rolling tank can elevate the comfort and safe of the boats
實踐表明，該水艙適用於多種類型船舶，不僅能減小船舶在波浪中的橫搖和抵抗靜傾角，還可以提高裝卸效率，減少運輸成本，為改善船舶的舒適性和安全性開辟了有效途徑。Seismic survey is a new method used to civil engineering area in recent years. it was widely applied to survey or detecting of roadbase, dam base, foundation of building, tunnel, river bed, lake bed and etc. the chief methods are reflection method, refraction method, wave velocity testing, surface ware survey and transverse wave suivey. seismic survey can divide different layer, measure the incidence of sediment stratum, detect the structure of rock, test the handle effect of surface wave survey, we can calculate the carrying capacity of foundation and other mechanical parameters. this technique can give service to some big engineering departments such as highway developing company, survey design company, water supply company, plan bureau, construct bureau etc
應用於工程的主要方法有反射波法折射波法波速測井面波法及橫波勘探等。地震勘探能詳細劃分地層高精度地確定沉積地層的傾角能夠準確探明巖體構造褶皺斷層破碎帶裂隙帶對于回填工程路基壩基，地震勘探可以檢測其回填處理效果對于隧道工程，可以探測隧道洞體的圍巖分類及洞口地質情況利用面波勘探所得到的瑞利波速度，可以準確推算地基的承載力動彈模量等力學參數。The wind magnitude and wind pressure can be easily adjusted in a wide range with a displaying device avilable. a well - illuminated air suction hood is equipped, which ensures clear observation of the movement of materials. besides, on both sides of the screen there are four holes available that make cleaning easy. the inclination angle of screen can be adjusted within a scope of 7 - 9. therefore, this machine is able to maintain stone - removing effect even the amount of material fluctuates. it can be used to remove the mixed stones in foodstuffs, grains, grease, feedstuffs and chemical products
調節風量風壓方便，且范圍大有顯示裝置，配有大採光吸風罩，物料運動一目了然配有先進照明燈觀察，篩體二側設有四個清理手孔清理方便，去石篩面傾斜角度可可、調范圍7 - 9 ，因此本機在產量波動范圍之內均能達到去石效果及用於去除不同種類，糧食、雜糧、油脂、飼料、化工其它等的並肩石。The experimental results of low - order modes correction for wave - front error and the enhancement of strehl ratio in detector and the improvement of wave - front tilt are also established
通過低階校正模式波前誤差提高了探測器接收光強，並有效校正了波前傾斜。By the simulation results, it is verified to have excellent performance. a class of uncertain nonlinear systems which can be transformed into strict feedback nonlinear systems is investigated based on feedback linearization approach of differential geometry. an adaptive robust controller with l2 - gain is proposed by using backstepping technique. the numerical method is given and it is proved to be practical by simulation results. lt is a more practical method to solve hji for a special nonlinear system because the problem to solve hji is very difficult in general case, and only get the approximate solution when it can be solved. an effective method to solve hji is presented for a class of nonlinear system which is ordinary
考慮到一般情況下，求解hji是非常困難的，並且也只能得到近似解，因此，在系統設計時，針對具體非線性系統的特殊結構以求解hfl是系統設計的一種行之有效的方法，基於以上考慮，對一類具有廣泛工程背景的非線性系統，提出了一種求解hfl的有效方法，便於實際應用。最後，從波能譜的角度，研究隨機海浪的模擬問題，給出了船舶橫搖模擬中需要的隨機海浪有效波傾角的模擬方法。分享友人
