How about an acetylene torch?
那不然用乙炔焊具囉？

It is of course a night fishing scene, and that light at the top is either the moon, or an acetylene gas lamp, which spear fishermen use to lure fish to the surface of the water.
這當然是夜釣的場景，頂部的光要麼是月亮，要麼是乙炔氣燈，魚叉漁夫用它把魚引到水面上。

We tried to dismantle the pump, starting with removing the bolts from the flanges, and they were so corroded that we couldn't get them loose by conventional means, so we elected to use an acetylene torch at that point.
我們試圖拆卸泵，首先要拆卸法蘭上的螺栓，但螺栓已嚴重腐蝕，用常規方法根本無法鬆開，是以我們選擇使用乙炔噴燈。

Marine Safety Committee Circular 1440, which can be found in the supplement to the IMDG code. Here is a simplified version of open versus closed containers on a container ship fitted with hatches. Part 7, chapter 5 provides a table for the user to determine the horizontal segregation of cargo transport units on row-row vessels. As with container ships, there is a table specifying the segregation requirements based on the four segregation groups defined earlier. The table identifies the segregation requirements for a thwart ships and fore and aft for both closed and open cargo transport units. The segregation requirements are specified in terms of distance, bulkheads and whether on deck or under deck. Again, illustrations regarding the segregation requirements are shown in IMO Marine Safety Committee Circular 1440, in the supplement to the IMDG code. Part 7, chapter 6 of the IMDG code applies to segregation of packaged dangerous goods stowed in the conventional way. This includes particular segregation from foodstuffs. The different segregation requirements are specified in terms of horizontal distance and vertical separation from packages containing incompatible dangerous goods. This takes into account any fire and liquid resistant compartments when considering vertical segregation. Where dangerous goods in packages are stowed together with a cargo transport unit containing dangerous goods, no segregation between the packages and the cargo transport is needed when away from is required. Where separated from is required, the segregation for away from is sufficient. Where segregation between packaged dangerous goods and those carried in bulk under the IMBSC code, the segregation requirements are specified in a table similar to the segregation table specified earlier. The definitions of the four segregation terms are also defined for such a stowage arrangement in a similar way as described earlier in this section. Before we move on to the next chapter, let's consider some questions. The following two closed cargo transport units are to be stowed on a row-row cargo area on the deck. CTU-A, UN-1469, lead nitrate PG-2. CTU-B, UN-3291, clinical waste PG-2. Using the IMDG code, which one of the following is the minimum horizontal level of segregation that meets the IMDG code? The following consignment is to be stowed as general cargo on a supply boat. UN-3374, acetylene, solvent free. Which of the following are specific stowage requirements for this consignment? The following cargo needs to be carried on deck with a general cargo ship with conventional stowage arrangements.
海事安全委員會第 1440 號通知，見《國際海運危險品準則》補編。這是裝有艙口的集裝箱船上開放式貨櫃與封閉式貨櫃的簡化版本。第 7 部分第 5 章提供了一個表格，供用戶確定行列式船舶上貨物運輸單元的水準隔離。與集裝箱船一樣，該表根據前面定義的四個隔離組別規定了隔離要求。該表還確定了阻擋船以及封閉式和開放式貨物運輸裝置前後的隔離要求。隔離要求按距離、艙壁以及甲板上還是甲板下進行了規定。同樣，國際海事組織海事安全委員會第 1440 號通知（IMO Marine Safety Committee Circula
