《文明4》科研计算公式

Technology Costs科技成本
To calculate the technology cost of a technology:
要计算一项科技的成本：
1) Take the base cost of the technology. (This can be found for each technology in Assets\XML\Technologies\CIV4TechInfo.xml).
1）取科研的基本成本（在Assets\XML\Technologies\CIV4TechInfo.xml中有所有科技的资料）。
2) Multiply 1) by the Difficulty Modifier and take the FLOOR of the product. (The difficulty modifier can be found in Assets\XML\CIV4HandicapInfo.xml.)
2）将1）乘以难度修正，并将结果下取整（难度修正在Assets\XML\CIV4HandicapInfo.xml中）。
3) Multiply 2) by the Map Modifier and take the FLOOR of the product. (The map modifier can be found in Assets\XML\CIV4WorldInfo.xml.)
3）将2）乘以地图修正，并将结果下取整（地图修正在Assets\XML\CIV4WorldInfo.xml中）。
4) Multiply 3) by the Speed Modifier and take the FLOOR of the product. This generates the actual cost of the technology. (The speed modifier can be found in Assets\XML\CIV4GameSpeedInfo.xml.)
4）将3）乘以速度修正，并将结果下取整，便能得出科技的实际成本（速度修正在Assets\XML\CIV4GameSpeedInfo.xm中）。
Thus the formula to calculate a Technology's cost is:
因此，计算科研成本的公式为：
Technology Cost = FLOOR (FLOOR (FLOOR (Base Cost * Difficulty Modifier) * Map Modifier) * Speed Modifier)
科研成本 ＝ 下取整（下取整（下取整（基本成本 * 难度修正）* 地图修正）* 速度修正）
Applying the Research to the Technology
将科研代入科技
The amount of beakers applied to the technology cost is dependant upon the number of civilizations which know the tech and the number of requirements you have fulfilled for the technology.
应用于某项科技的烧杯数量取决于已经掌握该科技的文明数量和玩家对该科技的要求的达成数量。

Calculating the Known Civilizations w/ Tech modifier计算已有文明掌握科技的修正？？
1) Multiply 0.30 by the number of KNOWN, LIVING civilizations, who have the tech.
1）已知的、已掌握该科技、并且存活的文明数量乘以0.3。
2) Divide by the number of civilizations which STARTED on the map and ROUND DOWN to the hundredth place (0.01) of the quotient.
2）【将1）】除以起始文明的数量，并在百分位（hundredth place of the quotient）取整。？？本句似有语病。
3) Add 2) to 1
3）将2）加1
Tech Known by Civilizations modifier = 1 + RDDW (0.30 * # known Civs who have the tech / # of Civs who started the game
其它文明已掌握的科技修正 ＝ 1 + 取整（0.30 * 已知掌握该科技的文明数量 / 参与游戏的文明总数）

Calculating the Prerequisites modifier计算前提（prerequisites）修正
1) Start with 1. If the technology does NOT have a minimum requirement (i.e., the starting techs = Fishing, The Wheel, Agriculture, Hunting, Mysticism, Mining), then use 1 AS the modifier.
1）如果该科技无最低要求（例，起始科技＝捕鱼、车轮、耕作、狩猎、神话、采矿），设修正值为1。
2) Add 0.2 to 1) if a Technology has a MINIMUM Requirement that the player has met. Note: Even if a tech has MANY MANDATORY PREREQUISITES, it will still only give you a boost of 1.2 because you MUST have all those prerequisites to research the tech. (IOW, the minimum requirement IS all of those prerequisites.)
2）如果玩家达到了该科技的最低要求，给1）加0.2。注意：即使一项科技有许多强制前提，它的修正值仍是1.2，因为玩家必须满足所有条件才能展开研究（换句话说（这明明素俺滴口头禅），最小要求即全部前提）。
3) Add 0.2 to 2) for EACH ADDITIONAL OPTIONAL Prerequisite that the player has met.
3）玩家每满足一条选择性前提，都给2）加0.2。
Requirements modifier = 1 + (0.2 * MINIMUM Req. met) + (0.2 * # of Optional Prereq. met)
前提修正 ＝ 1 +（0.2 * 满足最小前提）+（0.2 * 满足非强制前提的数量）

Calculating the Actual Amount of Beakers Generated Toward a Tech计算投入一项科技的实际烧杯量
To calculate the amount of beakers which you generate toward the technology:
要计算投入该科技的烧杯数量：
1) Take the total sum of beakers generated by all your cities (the result from the basics part).
1）得出所有城市的烧杯总量（基础部分的得数）
2) Add 1 to it if you have a city.
如果玩家有一个城市，1）加1。？？
3) Multiply 2) by the Known Civilizations w/ Tech modifier and take the FLOOR of the product.
3）用2）乘以计算已有文明掌握科技的修正，并取整。
4) Multiply 3) by Prerequisites modifier and take the FLOOR of the product.
4）用3）乘以前提修正，并取整。
The formula to calculate the amount of beakers applied to your technology is:
Beakers applied to Technology = FLOOR (FLOOR ((Total Base Beakers + 1) * KCwT modifer) * Prerequisites modifier)
计算投入科研的烧杯总量的公式为：
投入该科技的烧杯 ＝ 下取整（下取整（（基础烧杯总量 + 1）* 有接触文明掌握科技的修正）*（前提修正）
