1·The agreement between the buyer and seller is referred to in legal terms as a conditional sales contract. Quite often a down payment is required.

卖方与买方之间的这一协议，从法律的角度就是一种有条件合同，往往需先支付一笔定金。

2·Since the conditional sales contract is a security agreement relating to specific equipment, the conditional sales contract is now the type of collateral called chattel paper.

由于该附条件买卖合同是涉及特定设备的担保协议，所以附条件买卖合同现在就是一种叫做‘动产契据’的担保品了。
