tin /ˈtɪn/ 名詞
Tin n.
1. Chem. An elementary substance found as an oxide in the mineral cassiterite, and reduced as a soft silvery-white crystalline metal, with a tinge of yellowish-blue, and a high luster. It is malleable at ordinary temperatures, but brittle when heated. It is softer than gold and can be beaten out into very thin strips called tinfoil. It is ductile at 2120, when it can be drawn out into wire which is not very tenacious; it melts at 4420, and at a higher temperature burns with a brilliant white light. Air and moisture act on tin very slightly. The peculiar properties of tin, especially its malleability, its brilliancy and the slowness with which it rusts make it very serviceable. With other metals it forms valuable alloys, as bronze, gun metal, bell metal, pewter and solder. It is not easily oxidized in the air, and is used chiefly to coat iron to protect it from rusting, in the form of tin foil with mercury to form the reflective surface of mirrors, and in solder, bronze, speculum metal, and other alloys. Its compounds are designated as stannous, or stannic. Symbol Sn (Stannum). Atomic weight 117.4.
2. Thin plates of iron covered with tin; tin plate.
3. Money. [Cant]
Block tin Metal., commercial tin, cast into blocks, and partially refined, but containing small quantities of various impurities, as copper, lead, iron, arsenic, etc.; solid tin as distinguished from tin plate; -- called also bar tin.

tin
n 1: a silvery malleable metallic element that resists corrosion;
used in many alloys and to coat other metals to prevent
corrosion; obtained chiefly from cassiterite where it
occurs as tin oxide [syn: Sn, atomic number 50]
2: metal container for storing dry foods such as tea or flour
[syn: canister, cannister]
3: airtight sealed metal container for food or drink or paint
etc. [syn: can, tin can]
v 1: plate with tin
2: preserve in a can or tin; "tinned foods are not very tasty"
[syn: can, put up]
3: prepare (a metal) for soldering or brazing by applying a
thin layer of solder to the surface
[also: tinning, tinned]
tin
Symbol: Sn
Atomic number: 50
Atomic weight: 118.69
Silvery malleable metallic element belonging to group 14 of the periodic
table. Twenty-six isotopes are known, five of which are radioactive.
Chemically reactive. Combines directly with chlorine and oxygen and
displaces hydrogen from dilute acids.
Tin
Heb. bedil (Num. 31:22; Ezek. 22:18, 20), a metal well known in
ancient times. It is the general opinion that the Phoenicians of
Tyre and Sidon obtained their supplies of tin from the British
Isles. In Ezek. 27:12 it is said to have been brought from
Tarshish, which was probably a commercial emporium supplied with
commodities from other places. In Isa. 1:25 the word so rendered
is generally understood of lead, the alloy with which the silver
had become mixed (ver. 22). The fire of the Babylonish Captivity
would be the means of purging out the idolatrous alloy that had
corrupted the people.
