Technology Costs科技成本
To calculate the technology cost of a technology:
要計算一項科技的成本：
1) Take the base cost of the technology. (This can be found for each technology in AssetsXMLTechnologiesCIV4TechInfo.xml).
1）取科研的基本成本（在AssetsXMLTechnologiesCIV4TechInfo.xml中有所有科技的資料）。
2) Multiply 1) by the Difficulty Modifier and take the FLOOR of the product. (The difficulty modifier can be found in AssetsXMLCIV4HandicapInfo.xml.)
2）將1）乘以難度修正，并將結(jié)果下取整（難度修正在AssetsXMLCIV4HandicapInfo.xml中）。
3) Multiply 2) by the Map Modifier and take the FLOOR of the product. (The map modifier can be found in AssetsXMLCIV4WorldInfo.xml.)
3）將2）乘以地圖修正，并將結(jié)果下取整（地圖修正在AssetsXMLCIV4WorldInfo.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 AssetsXMLCIV4GameSpeedInfo.xml.)
4）將3）乘以速度修正，并將結(jié)果下取整，便能得出科技的實際成本（速度修正在AssetsXMLCIV4GameSpeedInfo.xm中）。
Thus the formula to calculate a Technology's cost is:
因此，計算科研成本的公式為：
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 * 難度修正）* 地圖修正）* 速度修正）
Applying the Research to the Technology
將科研代入科技
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.
應用于某項科技的燒杯數(shù)量取決于已經(jīng)掌握該科技的文明數(shù)量和玩家對該科技的要求的達成數(shù)量。

Calculating the Known Civilizations w/ Tech modifier計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、已掌握該科技、并且存活的文明數(shù)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）【將1）】除以起始文明的數(shù)量，并在百分位（hundredth place of the quotient）取整。？？本句似有語病。
3) Add 2) to 1
3）將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 * 已知掌握該科技的文明數(shù)量 / 參與游戲的文明總數(shù)）

Calculating the Prerequisites modifier計算前提（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）如果該科技無最低要求（例，起始科技＝捕魚、車輪、耕作、狩獵、神話、采礦），設修正值為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）如果玩家達到了該科技的最低要求，給1）加0.2。注意：即使一項科技有許多強制前提，它的修正值仍是1.2，因為玩家必須滿足所有條件才能展開研究（換句話說（這明明素俺滴口頭禪），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）玩家每滿足一條選擇性前提，都給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 * 滿足最小前提）+（0.2 * 滿足非強制前提的數(shù)量）

Calculating the Actual Amount of Beakers Generated Toward a Tech計算投入一項科技的實際燒杯量
To calculate the amount of beakers which you generate toward the technology:
要計算投入該科技的燒杯數(shù)量：
1) Take the total sum of beakers generated by all your cities (the result from the basics part).
1）得出所有城市的燒杯總量（基礎(chǔ)部分的得數(shù)）
2) Add 1 to it if you have a city.
如果玩家有一個城市，1）加1。？？
3) Multiply 2) by the Known Civilizations w/ Tech modifier and take the FLOOR of the product.
3）用2）乘以計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)
計算投入科研的燒杯總量的公式為：
投入該科技的燒杯 ＝ 下取整（下取整（（基礎(chǔ)燒杯總量 + 1）* 有接觸文明掌握科技的修正）*（前提修正）
