Under the same experimental conditions (with the same diameter) conditions, and the comparison of the arc performance between cerium tungsten electrode and tungsten thorium electrode is shown as below:
(1) Cathode spot
Cathode spot is associated with the life of the cathode spot; the comparative experiment of the two electrodes shows that, the cathode spot of cerium tungsten electrode’s tip electrode of is the smallest, so its loss is minimal, and therefore its life is longer than tungsten thorium electrode (the influence of organizational structure).
(2) Cathode voltage drop
2% Cerium - Tungsten 12.0 volts
2% thorium - tungsten 13.0 volts
(3) Electrode emission current density
Cerium tungsten electrode’s emission current density is higher than tungsten thorium electrode and its arc is bright and narrow.
(4) Minimum arc voltage
Under the same conditions, thorium tungsten electrode’s arc voltage electrode is: 30 V; whereas cerium tungsten electrode is 12 volts.
(5) Minimum stable arc current
In large diameter, both electrodes have minimum stable arc current, with the decrease of diameter, cerium tungsten electrode have a preferably arc current performance.

Scoring a tungsten dart match always looks easier the further you are from the chalkboard. Basic subtraction and addition can become incredibly difficult when you're in the spotlight, at the scoreboard. Here are a few things every darter should know before agreeing to be scorekeeper for tungsten dart match.
Scoring the match: the proper way to score an '01 match is to write the score per throw on the outside of the chalkboard and the total score on the inside, so the two opponent's scores are side by side on the inside of the scoreboard. For a cricket tungsten dart match, score the points at the top of the board and work your way down. You can note all stars next to the name of the darter at the top of the board. Also make sure that the scoreboard is easy to see from the dart line. Sometimes a scorekeeper will accidentally block the scoreboard by standing in front of it. Try to allow a clear view of the tungsten dart scores.
Act professionally and don't be afraid to ask questions. As a scorekeeper it's important to be calm. Make sure not to laugh, sneer or otherwise demean a bad throw. Also, do not establish rules after the game has begun. Never tell the thrower what double he has left or provide any strategy on how to finish the game. If you are not sure about a score, ask the thrower to confirm your math. Players should tell you the total scored per turn, however not all darters do this. If you're having difficulties recording a dart score, ask for help. Everyone knows how hot it is under the spotlight.

Follow The Leader Tungsten Dart Rule Ⅱ

For example, a player has to hit "S5" (the small wedge of the 5). With the first dart he hits the "S5". He now has two darts to set a new target. He aims at double bull ("D25") and hits it. He may now choose to sit down and not throw the third dart and leave the "D25". Let's say that, for some insane reason, he decides to try for a double 18, and misses off the board. He now loses a life and the next player now must hit "S5". The next player now gets up and hits the "S5" on his third dart. He pulls his darts and throws his first dart and hits "T20" (triple 20). Satisfied, he sits down choosing not to throw the other two darts.
If a player sets a target and all other players fail to match the target, when it's that players turn again, no throw is necessary. The player may choose to stay seated and keep the same target number. If the player chooses to risk trying a turn, the player must hit the target same as everyone else. If the player misses a life is lost just as if he did not set the number that stumped everyone else. It is usually wiser to just leave the number and not take the risk.
Strategy: There really isn't much strategy, just make sure when you setting the next target number that your last tungsten dart hits and stays in the board. It's better to leave the next player a big fat single-20 as a target than to have your last dart bounce-out of the double-bull.

Scoring a tungsten dart match always looks easier the further you are from the chalkboard. Basic subtraction and addition can become incredibly difficult when you're in the spotlight, at the scoreboard. Here are a few things every darter should know before agreeing to be scorekeeper for tungsten dart match.
No matter how tempting it is, don't look at the dart thrower on the line. As the scorekeeper for the tungsten dart match, you are in the line of sight for the players as they throw. Therefore, it is very important to stand still and face the dartboard. Whatever you do, don’t look directly at the players as they throw. This is very distracting for most dart throwers. Other "no-no's" are tapping the chalkboard, writing down scores per dart (always wait until all three tungsten darts have been thrown), and giving words of encouragement or advice to the tungsten dart thrower.
Scorekeeper's responsibilities: you are the official referee for the match, so it's important to know your responsibilities. You should call out the total score of each player's throw. As the scorekeeper, you can tell the darter how many points are required to finish the game. You also have the final decision on any controversy, such as who is closest to the middle of the dartboard. You may warn or disqualify the throw of a player stepping over the line. You can also re-adjust the dartboard if it is turned during a game.

Follow The Leader is a very simple yet fun game to play. It is very similar to the basketball game "Horse" (you may know that game under other names). It may be played by any number of players and is more fun with a lot of people. This game is actually pretty boring with only two players.
The Object: To win the game you must be the last player to have any lives left.
The Scoring: Players names are written in any order down the left side of the scoreboard. Usually, a throw of one dart each at bulls-eye with the closet player throwing first and the furthest throwing last. After the first game, the first player to get knocked out plays first and so on. Three tallies are marked next to each name to indicate the number of lives left.
The Play: The first player throws one tungsten dart left-handed (or right-handed if that player is a lefty) to set a random target. Because the first player has no chance to lose a life, the random throw is used to give the second player a fair chance.
The exact wedge or bulls-eye the tungsten dart landed is marked on the scoreboard. If the dart lands in the 5 between the triple ring and the bulls-eye, you would mark "S5" to indicate the small wedge of the 5. If the dart landed in the triple 5, you would write "T5". If the tungsten dart landed in the 5 between the triple and the double rings, you would write "B5" to indicate the big wedge of the 5. If the tungsten dart landed in the double 5, you would write "D5".
The next player now must try to land a tungsten dart in the exact same wedge of the board. If that player is fail with all three tungsten darts, one life is erased and the next player has a chance.
If the player is successful in matching the wedge any tungsten darts remaining in hand may now be used to score a new target. If the target was hit with the third dart, the player pulls the tungsten darts and has all three to establish a new target. All three tungsten darts need not been thrown in a turn the player may stop at any time after the number was matched and the last tungsten dart thrown at the board is the new target. The player may not make a choice of the darts thrown, only the last dart counts. If the player misses the board with the last dart that can be thrown, a life is lost and the target remains at the previous one set.
