Module:Chemicals（编辑 | 讨论 | 历史 | 链接 | 监视 | 日志）

本模組中包含一些與化學相關的函式

formula

本函式功能為查詢Module:Element/data資料並產生化學式

Usage:

{{#invoke:Chemicals|formula|<template-argument>}}

Parameters:

<template-argument>
要建構化學式的資料，必須使用模板引用傳遞參數
例如模板中寫 ：{{#invoke:Chemicals|formula}}
叫用模板 ：{{模板名稱|H|2|O}} → H2O

reaction

本函式功能為查詢Module:Element/data資料並產生反應式

Usage:

{{#invoke:Chemicals|reaction|<template-argument>}}

Parameters:

<template-argument>
要建構化學反應式的資料，必須使用模板引用傳遞參數
例如模板中寫 ：{{#invoke:Chemicals|reaction}}
叫用模板 ：{{模板名稱|H|2|O|+|C|O|2|eqm|H|2|C|O|3}} → H2O + CO2 化学平衡符号 H2CO3

check_CAS

函數原型（以C語言表示）：boolean_string 模块::Chemicals::check_CAS ( const string cas_no );

本函式功能為查詢檢查CAS號的格式與校驗碼是否正確，僅能由其他模組呼叫。

Datatype:

boolean_string
表示布林值的字串，其值僅會有 "true" 或 "false"

Parameters:

cas_no
要判斷的CAS號字串

check_CAS_test

本函式功能為查詢檢查CAS號的格式與校驗碼是否正確，可由模板呼叫。

Usage:

{{#invoke:Chemicals|check_CAS_test|1=<CAS_Number>}}

Parameters:

<CAS_Number>
要判斷CAS號是否正確的CAS號字串
例如 ：{{#invoke:Chemicals|check_CAS_test|1=12-35-1}} → true
通常會搭配{{#ifeq:...|true}}或{{#ifeq:...|false}}使用
例如 ：
{{#ifeq:{{#invoke:Chemicals|check_CAS_test|1=12-35-4}}|true|正確|錯誤}} → 錯誤
{{#ifeq:{{#invoke:Chemicals|check_CAS_test|1=12-35-1}}|false|{{Nay}}檢查碼校驗失敗|{{Aye}}檢查碼校驗成功}} → Green tickY檢查碼校驗成功
