　 (1) $this->getTemplateId()

　　<global>

　　　　<template>
            　<email>
                　　<customer_create_account_email_template translate="label" module="customer">
                    　　<label>New account</label>
                          <file>account_new.html</file>
                          <type>html</type>
                　　</customer_create_account_email_template>

　　　　　　</email>

　　　　<template>

</global>

　　$this->getTemplateId()表示上述配置中的customer_create_account_email_template。

　　(2) $this->getStoreId()

　　　　系统会根据$this->getStoreId()的值调用locale下的不同邮件模板。默认调用app/locale/en_US/template/email下的邮件模板

　　(3) $this->getTemplateParams()

　　　　邮件模板中的变量都来源于此
