Sudden Death tungsten dart rule is a very fast moving game for a large number of players. Playing with less than six player’s means the game will be over in two or three minutes.

The Object: To be the last person not eliminated.

The Scoring: No scoring are needed, all you have to do is remember playing order and what the lowest score thrown in each round is.

The Play: Each player (there are no teams in this game) throws one tungsten dart at bulls-eye, closest to the bulls-eye goes first.

Each player takes a turn trying to throw the highest possible score with three tungsten darts. Each tungsten dart scores the number where it landed with the thin outer "doubles" ring counting as two times the number hit and the thin inner "triples" ring counting as three times. The outer bulls-eye counts as 25 and the inner as 50 points.

After each player has thrown, whoever threw the lowest score that round is eliminated from the game and the next round is thrown with the remaining players. Whoever is left in the game at the end wins.

Strategy: Play your strongest numbers! A triple 16 (if that's your number) is a lot better score that floundering around the 20 and hitting 5's and 1's.

Tungsten carbide and pottery nozzle is tougher than metal nozzle and they have good anti-abrasion and anti-corrosion performance so that they improve the lifespan of nozzle. But they all belong to fragile materials and vulnerable, which is difficult to process and often used in making some simple structure nozzles and nozzle linings. The entrance of the nozzle should always wear high temperature and heat radiation by furnace in CWS atomizing processing. And CWS intensive leads cool the inner wall of nozzle, which come into being obvious temperature gradient and thermal stress. So the possibility of thermal shock and molder is remarkably increasing.

Battle Ship tungsten dart rule is a little complicated but a lot of fun game. It may be played with two players or teams. A pad and pen/pencil is required in addition to the scoreboard.

The Object: To sink all your opponent's ships before yours are sunk.

The Scoring: Players throw one tungsten dart each at bulls-eye, closest to the bulls-eye goes first.
The scoreboard is divided into two columns with a vertical line down the middle. Player’s names are written in order across the top of the board.

Four "ships" are drawn in each player’s column with one number in each: 2, 3, 4, 5. Each number represents how many positions on the board the ship occupies and also indicates the number of hits required to sink it.

The Play: Before the play begins, players must "hide" their ships by placing them on the board. Players write on a slip of paper the placement of each ship and do not disclose their placements to the opponents.

All five ships must be placed on the board and may not cross each other or be placed on top of each other. All ships must be places in sequential segments of the board and may not ever be broken up.

Ships may be oriented either "circularly" or "radially".(径向) To place a ship in a circular manner means that it's segments span numbers in the same ring of the board. The rings are the thin outer "double" ring, the large single wedge, the thin inner triple ring and the small single wedge. Bulls-eyes may not be used in circular placement. An example of circular placement would be to have your 3-segment ship across triple-20, triple-1 and triple-18 or small-11, small-8 and small 16.

Radial placement of a ship means placing the ship along the segments of one number like a spoke in a bicycle wheel. The bulls-eye may be used in radial placement along with any number. But remember that two or more ships may not share the same the same segment, so the bulls-eye may only be used for one ship. The bulls-eye is also counted as a single segments, no differentiation is made between the inner and outer bulls-eyes. An example of radial placement would be to have your 3-segment ship across triple-19, small-19 and bull another would be triple-6, large-6 and double-6.

Once both player ships have been hidden and written down on their slip of paper, play begins. Players take turns trying to locate and sink the other player's ships. This is done by randomly hitting segments of the board until a hit is scored. Each time a player throws a tungsten dart, the opponent must say "hit" or "miss" to indicate if the tungsten dart struck a section of any ship. No information is given as to which ship or how it is oriented should be given.

Once the initial hit is made, you must test all the segments surrounding the hit to try and determine the orientation of the ship and hit all of them. When all the segments of a ship have been hit, the player whose ship it is must announce "sunk" and cross out the ship which was sunk on their side of the scoreboard.

When you have sunk all your opponent’s ships, you have won the game.

Strategy: All your favorite strategies from the classic board game apply. If you have never played the board game, you have definitely wasted your childhood.

As oil, gas and other energy sources, one of the most ideal clean energy, CWS has so many advantages, such as good combustion efficiency, less environmental pollution, easy storage and transportation. The nozzle is one of the main components of CWS combustion boiler, and the most common of the three nozzle material is metal, tungsten carbide and pottery at present. Due to its excellent extensibility, metal is easy to process, which often used in complicated structure processing or for special purpose. However, metal has low hardness, bad anti-corrosion and short lifespan.

Different distance of tungsten carbide nozzle has different effects. The temperature of entrance changed because of the larger distance under high-powered operating, which increased the distribution coefficient of the entrance. While the performance of combustion engine is decreasing, it may be caused by the shorter distance, a great amount of nozzles or intensive distribution. Theoretically, each nozzle gets less oil supply and reduces the difference of oil pressure when the size and total oil supply is the same, which reduces the efficiency and the stability. Therefore, we should consider different height of platform and different atomizing pressure to design a reasonable nozzle distribution.

Tungsten does not occur by itself in nature. It is only present in different chemical compounds. For industrial purposes, the two most important minerals are tungsten-bearing wolframite ((Fe, Mn) WO4) - or, as some would call ferberite-Huberite and scheelite (CaWO4). These are the two minerals that are often exploited to produce tungsten.

China now dominates the primary production of tungsten in the world. The U.S. Geological Survey [USGS] Estimates of global mine production in 2007 that China produces some 77,000 tons of metal, 86% of world production.

Note: Andrew mine, northeast of Los Angeles, operated by Curtis tungsten, tungsten began shipping concentrates in October 2007, but the figures for these shipments are not disclosed.

In addition, the USGS has calculated that China is a reserve base for about 67% of the reserve base of the world total.

China has tradtionally been the world's leading tungsten producer, accounting for 85% of the world's production, estimated at 35 000 t of tungsten concentrate. China's tungsten production does not seem to be affected by the slump in global pruices as production remains at about 70% capacity. This compares to 10% production capacity exhibited by western producers. China's wolframite reserves are being rapidly depleted with an estimated 12 years reserves or 600 000 t remaining. Although China has substantial scheelite resources, they are of a much lower grade and quality.

The government exerts much control over the production of tugsten and in January 2004 the Ministry of Land and Resources ste the total allowable production quota of tungsten concentrate for the year at 43,660 t but the output in 2003 was more at 67,326 t, a 3.4% increase from 2002. Rapid development of the automotive machinery manufacturing, construction metals and communications industries increased domestic demand for tungsten, with 2003 consumption totalling an estimated 80,000 t. Exports of tungsten ore increased by 29% in 2003 to 32,987 t (US$220 million) and imports imports by 40% (US$33.7 million).

Jiangxi Tungsten Group Ltd which was formed in December 2003 has become the largest tungsten group in China. It is a joint venture between Jiangxi Rare Earth Metals Tugsten Group (The largest precious and rare metals group in China) and China Five Minerals Non-Ferrous Metals Ltd (the largest sales company in China).

There are a few minerals that will fluoresce when pure. These are called "self-activated" minerals, and include scheelite, powellite, and several uranium minerals. Others suspected of being self-activated include benitoite, cerussite, anglesite and perhaps many other lead minerals. Scheelite, a major ore of tungsten, is often found by its brilliant sky-blue fluorescence. If it has a little molybdenum in it (which makes it troublesome to extract the tungsten), this color is modified to white or yellow, providing a quick way to assess the commercial value of a find.

Several secondary uranium minerals, such as autunite, are also characteristically fluorescent a bright yellowish green. This is due to the presence of uranyl ion; this ion is so prone to fluorescence that trace amounts of it cause yellowish-green fluorescence in a very large number of minerals, including adamite, apophyllite, aragonite, calcite, quartz, and opal. Any yellowish-green fluorescence other than willemite is likely to be due to the uranyl ion.

Well over 3600 mineral species have been identified at this time; over 500 of them are known to fluoresce visibly in some specimens.

Most minerals do not fluoresce when pure. It takes certain impurities in certain quantities to make the mineral fluoresce. Such impurities are called "activators". Different activators can make the same mineral fluoresce in different colors. Different minerals require different activators, and in different quantities. There are also impurities, notably ferrous iron, that can prevent fluorescence despite the presence of an activator. Because the activators and deactivators may or may not be present in any given specimen, different specimens of the some mineral (especially from different locales) may vary in color and degree of fluorescence. A common fluorescent mineral is calcite. It comes in just about all the observed fluorescent colors due to different activators. Red and pink fluorescent calcites are often activated by a combination of lead and manganese.
