银行履约保函的关键词翻译和解析：
1.Irrevocable Letter of Credit：不可撤销信用证。这意味着一旦信用证开出，开证行就不能单方面修改或撤销，除非有受益人的书面同意。这是银行履约保函的一项重要保障，确保受益人的权益得到保护。
2.in favor of：向……开具。这表示信用证的受益人，即银行承诺付款的对象。
3.an amount not exceeding：金额不超过。这里规定了信用证的最高金额，银行的付款义务在该金额以内。
4.effective immediately：立即生效。信用证开出后立即生效，受益人可以随时根据其与义务人合同的履行情况要求付款。
5.undertake to honor：承诺付款。银行承诺，当受益人出具符合信用证条款的汇票和单据时，将及时付款。
6.draft(s) drawn on us：向我行出具的汇票。汇票是受益人要求银行付款的票据，必须符合信用证的要求才能得到付款。
7.International Chamber of Commerce：国际商会。国际商会制定了《跟单信用证统一惯例》（UCP600）和《保兑要求统一规则》（URDG758），是国际贸易中信用证和保函业务的重要规则。
8.Uniform Customs and Practice for Documentary Credits：跟单信用证统一惯例。这是一套关于信用证的国际惯例，规定了信用证的定义、开证、修改、付款、退单等各个环节的处理办法。
9.Uniform Rules for Demand Guarantees：保兑要求统一规则。这是一套关于保函的国际惯例，规定了保函的定义、要求、修改、付款、争议解决等方面的规则。
10.subject to：受……约束。这表示信用证的适用规则，受益人和开证行都必须遵守这些规则。
11.evidence satisfactory to us：令我行满意的证据。如果义务人能够提供证据证明其已履行合同义务，银行有权取消信用证。这保护了义务人的权益，防止受益人不当索赔。
以上就是银行履约保函的英文模板翻译和解析。银行履约保函是国际贸易中的一种重要担保工具，它由独立于合同交易的第三方（银行）出具，保证了交易的安全性。银行履约保函的英文模板可以作为参考，但实际业务中需要根据交易的具体情况进行修改和调整，以确保履约保函能够有效地保护各方利益。
