But our patron warn d by this disaster, resolved to take more care of himself for the future ; and having lying by him the long - boat of our english ship we had taken, he resolved he would not go a fishing any more without a compass and some provision ; so he ordered the carpenter of his ship, who also was an english slave, to build a little state - room or cabin in the middle of the long boat, like that of a barge, with a place to stand behind it to steer and hale home the main - sheet ; and room before for a hand or two to stand and work the sails ; she sail d with that we call a shoulder of mutton sail ; and the boom gib d over the top of the cabbin, which lay very snug and low, and had in it room for him to lye, with a slave or two, and a table to eat on, with some small lockers to put in some bottles of such liquor as he thought fit to drink in ; particularly his bread, rice and coffee
他就下令他船上的木匠-也是他的一個英國人奴隸-在長舢舨中間做一個小艙，像駁船上的小艙那樣艙后留了些空間，可以容一個人站在那裡掌舵和拉下帆索艙前也有一塊地方，可容一兩個人站在那裡升帆或降帆。這長舢舨上所使用的帆叫三角帆，帆桿橫垂在艙頂上。船艙做得很矮，但非常舒適，可容得下他和一兩個奴隸在裏面睡覺，還可擺下一張桌子吃飯桌子里做了一些抽屜，裏面放上幾其他愛喝的酒，以及他的麵包大米和咖啡之類的食物和飲料。Dilution and dispersion in constant horizontal flow and bottom multi - port discharging was studied in accordance with the hydraulic model test. the influence of diffusion parameters ( jet angle, jet velocity, number of nozzle, riser space ) and environmental parameters ( water depth, water velocity ) on dilution were analyzed. the experimental results show that environmental parameters have prominent effects on wastewater dilution and dispersion, in addition to that, diffuser design parameters have significant influence on wastewater dilution and dispersion. for bailonggang outfall zone, jet angel is 10 or so, nozzle number is 16 or so
藉助於人工模型試驗，分析了恆定橫流底部多孔排放時擴散器設計參數（射流角度、射流速度、噴口個數） 、上升管間距）及環境參數（環境水深、環境流速）對污水近區稀釋擴散效果的影響，實驗結果表明，除了環境條件對污水稀釋擴散效果影響明顯之外，擴散器設計參數對污水的近區稀釋擴散也有顯著的影響，針對白龍港排放口水域，噴口射流角度宜控制在10左右，噴口個數取16個In this paper, the foundamental principles of fd _ bpm ( finite - difference beam propagation method ) used to simulate and calculate the process of beam propagation is first introduced. then ， the theory of boundary condition is carefully presented. based on those theories mentioned above, a new kind of fd _ bpm arithmetic is brought forward. compared with the traditional arithmetic, this one has much more advantages. in virtue of the new arithmetic, author accomplished the whole simulating designs with two kinds of optical splitter ( stright y - junction optical splitter and sine - type optical splitter ), including propagation field simulating, vital parameter calculating, acquired some optimized waveguide parameters ， and finished the template by those results at last
本文主要藉助這種改進的fd _ bpm演算法，對兩種結構的光分路器（直y型光分路器，上升正弦型光分路器）進行了器件設計的軟體模擬，包括對兩種結構光分路器傳輸場進行模擬，並對兩種結構光分路器的重要參數，如波導寬度，分叉角，縱橫比，損耗進行了模擬計算；得到了一些有價值的優化波導結構參數值，根據這些優化值設計製作了光刻模板。
