本文的研究分為二個部分：首先利用frank源匯法計算水動力系數，計算包括不同吃水時的附加質量和阻尼系數，吃水范圍涵蓋了船舶大幅度運動時所有可能的吃水；然後建立和求解船舶大幅度運動方程，在實際計算時一方面考慮了運動模態之間的耦合，另一方面在計算水動力時，考慮了非線性因素的影響。 froude - krylov力、輻射力、繞射力中的水動力系數隨吃水瞬時變化，靜浮力的計算精確到船體瞬時濕表面積，最後用四階龍格?庫塔方法在時域內求解船舶運動方程，並進行了載荷計算。In general, the upward amplitude curve " curvature is larger, and it changes quicker. on the contrary, the downward is smaller and slower ; because the flare force contains the square of the wave elevation velocity, it results in an difference between the flare force frequence and the associated moving frequence ; the flare force decreases the downward amplitude of heaving oscillations ; the speed of ship has an ignorant effect on the peak values of three calculated values, but there is an obvious effect on the oscillating frequence ; the wave amplitude has an effect on the ship motion, and there is an linear relation between the oscillating amplitude and the wave amplitude on the whole. by the way, there are some experiences and lessons according to the progress calculation : before the calculation of the ship motion, we should checkout the balance in a calm water firstly, namely, the whole displace of ship and the longitudinal position of the center of gravity must be consistent with the draft in calm water, or else, the calculation may show the " floating " phenomenon ; the mixed language programming has a lot of virtues, but it exists a fatal limitation - the debug of dll
研究表明：在某些頻率范圍內相關水動力系數基本不隨吃水變化，只有超過某一頻率后水動力系數的值才會出現差異；在橫搖方向，水動力系數並沒有隨著吃水的變化發生規則變化，而是出現了波動現象；近船首剖面的水動力系數計算表明，水動力系數的波動非常大，並遠遠偏離了平均位置的水動力系數值，值的變化速率也不盡相同，總的看來，上振幅曲線曲率較大，變化較快，下振幅曲線曲率較小，變化較慢；外飄力和波面運動的速度的平方項有關，導致其振動頻率和相應運動方向的頻率不同；外飄力使升沉向下運動的幅值減小；船速對三個計算量的峰值影響甚微，但對振動頻率有明顯影響；波幅對船舶運動的影響是明顯的，船舶運動的幅值基本上和波幅成線性關系。Reality needs such a product, it contains a high dietary fiber content, reaching general vegetables, fruit of over 20 times ; their basic no calories, need not worry about eating more obesity ; at the same time, both for staple foods, such as rice free to join in, or do bao zi, 蔥 油餅, india parabolic cake medium can add, let alone in the cold, cooking, 煲湯, pot, how many changes can be delicious, tempting delicacies, people did not worry about eating
現實需要這樣一種產品，它含有極高的膳食纖維含量，達到一般蔬菜、水果的20倍以上；本身基本無熱量，不用擔心吃多了發胖；同時，既能用於主食中，像隨意加入米飯中，或做包子、蔥油餅、印度拋餅中等都能添加，更不用說在涼拌、炒菜、煲湯、火鍋中，可變化出多少美味誘人的佳肴，讓人吃了沒有后顧之憂。Please give me the tpc and trimming table
請把百噸吃水變化表給我。When ships are at their actual voyages the working conditions ( such as loading, depth of drafu ship speed ) and the navigating environments ( such as the sea route, depth of water, wind, wave, current ) are variable to a large extent. the whole during is a procedure of model varying with time nonlinear and large disturbance. the introduction of the intelligent controlling method can contribute to the improvement of automation degree for ship avoiding collision and maneuvering systems
由於船舶的運動在實際的航行過程中隨船舶的工作狀態（如載荷、吃水深度、航速等）及航行環境（如航線、水深、風、浪、流等）的不同而有很大的變化，是一個模型時變、非線性、大幹擾的過程，將智能化控制技術用於其中將會有助於船舶避碰與操縱系統的自動化程度的提高。The conclusion from the experiment is that the ratio of reduced resistance is relevant with the velocity of water stream, gas flux, the waterline of ship model and the dashplate
結果表明：減阻率的變化與水流速度、噴氣量、船模的吃水，以及有無壓浪板有關。This method is a novel, simple method calculating the ocean wave force on floater. you can find the rule between ocean wave force and time at any moment, and get the biggest ocean wave force on floater if you give the actual instance of the sea, the geometrical dimension of the floater and the depth of the floater in the water
這種計算方法是一種新穎的計算漂浮體上波浪力的簡單方法，在計算波浪力的過程中，只需要給出實際海況，浮子幾何大小，以及浮子吃水深度就可以求得波浪力隨時間的變化規律，並可求得浮子所受的最大波浪力。Ice cream lovers can help fight global warming by seeking out ice creams flavoured with local berries, fruits and nuts, an italian farmers " group says. papaya ice may be nice, but it takes 5. 4 kg of oil - with the attendant co2 that releases into the atmosphere - to transport one kg 2. 2 lb of the fruit from argentina to rome, coldiretti said in a statement over the weekend
據路透社4月23日的報道，這家名為coldiretti的團體于上周末在其發表的一份聲明中指出，木瓜冰淇淋也許真的非常好吃，但要將1公斤2 . 2磅此種水果從阿根廷運到義大利首都羅馬來則需要消耗掉5 . 4公斤石油，與此同時，還會有大量的二氧化碳被排放到空氣中，而這種氣體已經被視為導致全球氣候變暖的主要罪魁禍首之一。分享友人
