  1. The corbel ' s dimension should be ascertained as the manipulative condition of diagonal section. the amount of longitudinal reinforcement be ascertained on the basis of the flexure model, is obtained according to static for balance condition, the calculative expression of the load is obtained. and in terms of the design method in ultimate state the maximum load

    我國規范對于牛腿的設計規定，牛腿尺寸的確定以斜截面抗裂作為控制條件，縱筋用量的確定以彎壓破壞模型為基礎，根據靜力平衡條件得到承載力的計算公式，按照極限狀態設計方法計算得到，箍筋用量則按照構造要求確定。
  2. There is a chemical reserve zone in the stack. in this zone the fe is present as feo, and the gas component is close to the balance composition of fe0. 947o / fe. so there is a part of longitudinal section, in which : l ) gas keeps its component, as ascending. 2 ) the composition of the gas is close to the equilibrium composition of the fe0 947o + co - " 0. 947fe + co2 under the temperature of the thermal reserve zone of about 1200 + 100k

    根據冶煉理論，高爐在爐身一定高度上有一個「化學貯備區」 ，在該區，含鐵物料實際上都是浮氏體，並且煤氣成分接近fe _ （ 0 . 947 ） o fe平衡時的成分，這樣，高爐內存在高爐熱控制模型開發一個縱向區域，在該區內：二）煤氣上升時，成分不變。
  3. Chain saws - specification for longitudinal balance

    鏈鋸.第10部分:縱向平衡規范
  4. The model considers the torsional deformation of transmission axes, bending and longitudinal deformation of links, geometrical nonlinearity of guiding leaf springs, and the elastic nonlinearity of balance springs

    該模型考慮了傳動軸的扭轉變形，連桿和導向板彈簧的彎曲和拉伸變形，導向板彈簧的幾何非線性及平衡彈簧的非線性等因素的影響。
  5. 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。
