harpoons

harpoons are hand-held or fired from a harpoon gun aimed at individual, high-valued fish, such as giant tuna or swordfish.

鱼叉是手持或者从渔枪瞄准高价鱼类，例如庞大的鲔鱼或剑旗鱼，再射出的。

Submarine-launched Harpoons are pre-loaded into a capsule and launched from a torpedo tube. The capsule rises to the surface and launches the missile.

潜水艇把发射的鱼叉预先放入胶囊，从鱼雷发射管射出，胶囊上升到表面，发射。

Even then, not everything went to plan, and two decades of meticulous planning could have failed within minutes at touchdown. Philae's anchoring harpoons didn't fire as planned, and it bounced off the comet before settling onto its icy surface and successfully beaming data back to its relieved creators.

可即便是花了20年设计、缜密计划过的菲莱还是在着陆的几分钟里有点小失败：“鱼叉”系统未如计划打开，无法准确钉入彗星表面。不过幸运的是，菲莱还是成功地把数据发回了地球。
