| 释义 | 〔unpracticed〕Not yet tested or tried.尚未测验的或试用的〔shrapnel〕Henry Shrapnel received no compensation for the invention named after him other than having his name live on in connection with it.This deadly artillery shell, invented by Shrapnel, a British artillery officer, in his spare time and at his own expense,was given its first test in South America during the British seizure of part of Suriname (1799-1802),but shrapnel came into its own during the Peninsular War (1808-1814) between Great Britain, Spanish guerrillas, Portugal, and Napoleonic France.Shrapnel's shell was first officially called thespherical case shot, but it seems that early on it was called theshrapnel shell as well (first recorded in 1806), and this was the name eventually adopted by the British army.The wordshrapnel came to be used by itself as a collective noun, and even though the shrapnel shell is no longer used,people have for some time (first recorded in 1940) called the fragments from a shell, mine, or bombshrapnel, thus ensuring the continued existence, if not the immortality, of Henry Shrapnel's name.亨利·宣普纳因这种以其名字命名的发明，除了他的名字跟这种发明联系在一起以外他一无所获。宣普纳是一位英国炮兵军官，这种致命的武器是他在闲暇时间自筹经费发明的。它的首次试用是在南美洲英国占领部分苏里南领土期间（1799-1802年）进行的，但在大布列颠、西班牙游击队、葡萄牙及拿破仑统治下的法国几方之间进行的半岛战争期间（1804-1814年），榴霰弹开始使用。一开始宣普纳的这种炮弹被官方称作霰弹 。 但这之前似乎被称为shrapnel shell （最早记录于1806年）。 这一名字最终被英国陆军采用。shrapnel 一词被用作一集合名词， 虽然榴霰弹已不再使用了，但有一段时期人们把弹丸、地雷或炸弹的碎片也称为shrapnel （最早记录于1940年）， 这样就确保了亨利·宣普纳的名字得以继续存在，即使不能永存的话〔experiment〕A test under controlled conditions that is made to demonstrate a known truth, examine the validity of a hypothesis, or determine the efficacy of something previously untried.实验，试验：在受控条件下为演示一项已知真理、检验假说的正确性或确定以前未试用过的某物的效能而做的试验〔proof〕A trial photographic print.试用的照片印相〔shareware〕Copyrighted software that is available free of charge on a trial basis, usually with the condition that users pay a fee for continued use and support.共有软件：可免费试用的受版权保护的软件，若继续使用及获得支持，使用者通常要付费〔proof〕To make a trial impression of (printed or engraved matter).印…的校样：做（印刷或雕刻物）的试用印张〔trial〕Made or done in the course of a trial or test.试用的，试验的：在试验或测试过程中完成或形成的〔trial〕The act or process of testing, trying, or putting to the proof:试验：检验、试用或验证的行为或过程：〔experiment〕To try something new, especially in order to gain experience:尝试：试用新事物，尤指为获得经验： |
