In the study of the lumber carrier, one of the very important problem is the in spot and ultimate station due to flooding which will bring tremendous threat to the ship because of the few holds in order to study the lumber carrier buoyancy, stability and longitudinal strength under the condition of flooding, the paper adopt fundamental ship principle and iterative and accumulative concept on the basis of insumersibility theory to detailedly calculate the flooding speed flooding amount front draft after draft stability and longitudinal strength considering the ship " s sinking and inclination which will change the center of gravity and the loading station both in hold and on deck and the effect of flooding and lumber amount in holdo in the last, the paper introduces an example of the actual ship named " fei yun ling " and makes a contrast between not taking measure and taking measure which draws a reasonable conclusion and comes up to some advice the method avoids the cockamamie calculating while insures enough precision the paper draws a conclusion that not all the lumber carrier will submerge when suffering the damaged flooding if the loading or measure is suitable
為了研究運木船舶在破艙狀態下的浮性、穩性和強度,本文在抗沉性理論的基礎上,運用船舶基本原理,採用了迭代和累計的思想,將船舶的
進水過程劃分為很多次
進水的積累,詳細計算了運木船在破艙
進水的過程中,考慮到各種破艙參數、船舶本身的下沉、艙室內木材、甲板貨的裝載情況和在
進水過程中船舶本身的傾斜對
進水重心的影響,以及艙室內的
進水量和木材對破口處
進水速度的影響,船舶總的

進行了在採取用泵抽
水前後浮態參數的對比,得出了該船舶在艙室內的貨物積載量達到某個數值時可以保證船舶在破艙
進水時不會沉沒,或者在當開口小於某數值時,採取適當的措施后,可以使船舶避免沉沒。

The water current flows over the top of the dentoid baffle to the hydraulic jump as additional momentum. while it is cooperated with a stilling basin, the flowing condition emerged in the basin may be improved greatly and the length and downstream water depth required by the basin can be decreased to a great extent. such an appliance may be also used to solve the problems of insufficiently dissipating water flow energy and aerating flow, which are often faced with those hydraulic engineering constraction as acted by high waterhead, great specific discharge and low froude number
