请帮我分析“介词+whose+名词”的句型结构及语法
Applicant means the party on whose request the credit is issued.
申请人是指发出开立信用证申请的一方.
没有on one's request这一短语,也没有be issued on/in这一短语.有issue in,但是此时issue是不及物动词无法用被动态.
同例：Beneficiary means the party in whose favour a credit is issued.受益人是指信用证中受益的一方.
没有搜到in one's favour的短语
找到 in one's favour了，对……有利=to one's advantage
