后无效。
（3）买方宣告合同对任何一批货物的交付为无效时，可以同时宣告合同对已交付的或今后交付的各批货物均为无效，如果各批货物是互相依存的，不能单独用于双方当事人在订立合同时所设想的目的。 Article 73
(1) In the case of a contract for delivery of goods by instalments, if the failure of one party to perform any of his obligations in respect of any instalment constitutes a fundamental breach of contract with respect to that instalment, the other party may declare the contract avoided with respect to that instalment.
(2) If one party's failure to perform any of his obligations in respect of any instalment gives the other party good grounds to conclude that a fundamental breach of contract will occur with respect to future instalments, he may declare the contract avoided for the future, provided that he does so within a reasonable time.
(3) A buyer who declares the contract avoided in respect of any delivery may, at the same time, declare it avoided in respect of deliveries already made or of future deliveries if, by reason of their interdependence, those deliveries could not be used for the purpose contemplated by the parties at the time of the conclusion of the contract.
第二节 损害赔偿 Section II-Damages
第七十四条
一方当事人违反合同应负的损害赔偿额，应与另一方当事人因他违反合同而遭受的包括利润在内的损失额相等。这种损害赔偿不得超过违反合同一方在订立合同时，依照他当时已知道或理应知道的事实和情况，对违反合同预料到或理应预料到的可能损失。 Article 74
Damages for breach of contract by one party consist of a sum equal to the loss, including loss of profit, suffered by the other party as a consequence of the breach. Such damages may not exceed the loss which the party in breach foresaw or ought to have foreseen at the time of the conclusion of the contract, in the light of the facts and matters of which he then knew or ought to have known, as a possible consequence of the breach of contract.
第七十五条
如果合同被宣告无效，而在宣告无效后一段合理时间内，买方已以合理方式购买替代货物，或者卖方已以合理方式把货物转卖，则要求损害赔偿的一方可以取得合同价格和替代货物交易价格之间的差额以及按照第七十四条规定可以取得的任何其他损害赔偿。 Article 75
If the contract is avoided and if, in a reasonable manner and within a reasonable time after avoidance, the buyer has bought goods in replacement or the seller has resold the goods, the party claiming damages may recover the difference between the contract price and the price in the substitute transaction as well as any further damages recoverable under article 74.
第七十六条
（1）如果合同被宣告无效，而货物又有时价，要求损害赔偿的一方，如果没有根据第七十五条规定进行购买或转卖，则可以取得合同规定的价格和宣告合同无效时的时价之间的差额以及按照第七十四条规定可以取得的任何其它损害赔偿。但是，如果要求损害赔偿的一方在接收货物之后宣告合同无效，则应适用接收货物时的时价，而不适用宣告合同无效时的时价。
25
（2）为上一款的目的，时价指原应交付货物地点的现行价格，如果该地点没有时价，则指另一合理替代地点的价格，但应适当地考虑货物运费的差额。 Article 76
(1) If the contract is avoided and there is a current price for the goods, the party claiming damages may, if he has not made a purchase or resale under article 75, recover the difference between the price fixed by the contract and the current price at the time of avoidance as well as any further damages recoverable under article 74. If, however, the party claiming damages has avoided the contract after taking over the goods, the current price at the time of such taking over shall be applied instead of the current price at the time of avoidance.
(2) For the purposes of the preceding paragraph, the current price is the price prevailing at the place where delivery of the goods should have been made or, if there is no current price at that place, the price at such other place as serves as a reasonable substitute, making due allowance for differences in the cost of transporting the goods.
第七十七条
声称另一方违反合同的一方，必须按情况采取合理措施，减轻由于该另一方违反合同而引起的损失，包括利润方面的损失。如果他不采取这种措施，违反合同一方可以要求从损害赔偿中扣除原可以减轻的损失数额。 Article 77
A party who relies on a breach of contract must take such measures as are reasonable in the circumstances to mitigate the loss, including loss of profit, resulting from the breach. If he fails to take such measures, the party in breach may claim a reduction in the damages in the amount by which the loss should have been mitigated.
第三节 利息 Section III-Interest
第七十八条
如果一方当事人没有支付价款或任何其它拖欠金额，另一方当事人有权对这些款额收取利息，但不妨碍要求按照第七十四条规定可以取得的损害赔偿。 Article 78
If a party fails to pay the price or any other sum that is in arrears, the other party is entitled to interest on it, without prejudice to any claim for damages recoverable under article 74.
第四节 免责 Section IV-Exemptions
第七十九条
（1）当事人对不履行义务，不负责任，如果他能证明此种不履行义务，是由于某种非他所能控制的障碍，而且对于这种障碍，没有理由预期他在订立合同时能考虑到或能避免或克服它或它的后果。
（2）如果当事人不履行义务是由于他所雇用履行合同的全部或一部分规定的第三方不履行义务所致，该当事人只有在以下情况下才能免除责任： （a）他按照上一款的规定应免除责任，和
（b）假如该项的规定也适用于他所雇用的人，这个人也同样会免除责任。 （3）本条所规定的免责对障碍存在的期间有效。
（4）不履行义务的一方必须将障碍及其对他履行义务能力的影响通知另一方。如果该项通知在不履行义务的一方已知道或理应知道此一障碍后一段合理时间内仍未为另一方收到，则他对由于另一方未收到通知而造成的损害应负赔偿责任。
26
（5）本条规定不妨碍任何一方行使本公约规定的要求损害赔偿以外的任何权利。 Article 79
(1) A party is not liable for a failure to perform any of his obligations if he proves that the failure was due to an impediment beyond his control and that he could not reasonably be expected to have taken the impediment into account at the time of the conclusion of the contract or to have avoided or overcome it or its consequences.
(2) If the party's failure is due to the failure by a third person whom he has engaged to perform the whole or a part of the contract, that party is exempt from liability only if:
(a) he is exempt under the preceding paragraph; and
(b) the person whom he has so engaged would be so exempt if the provisions of that paragraph were applied to him.
(3) The exemption provided by this article has effect for the period during which the impediment exists.
(4) The party who fails to perform must give notice to the other party of the impediment and its effect on his ability to perform. If the notice is not received by the other party within a reasonable time after the party who fails to perform knew or ought to have known of the impediment, he is liable for damages resulting from such non-receipt.
(5) Nothing in this article prevents either party from exercising any right other than to claim damages under this Convention.
第八十条
一方当事人因其行为或不行为而使得另一方当事人不履行义务时，不得声称该另一方当事人不履行义务。 Article 80
A party may not rely on a failure of the other party to perform, to the extent that such failure was caused by the first party's act or omission.
第五节 宣告合同无效的效果 Section V-Effects of avoidance
第八十一条
（1）宣告合同无效解除了双方在合同中的义务，但应负责的任何损害赔偿仍应负责。宣告合同无效不影响合同关于解决争端的任何规定，也不影响合同中关于双方在宣告合同无效后权利和义务的任何其它规定。
（2）已全部或局部履行合同的一方，可以要求另一方归还他按照合同供应的货物或支付的价款，如果双方都须归还，他们必须同时这样做。 Article 81
(1) Avoidance of the contract releases both parties from their obligations under it, subject to any damages which may be due. Avoidance does not affect any provision of the contract for the settlement of disputes or any other provision of the contract governing the rights and obligations of the parties consequent upon the avoidance of the contract.
(2) A party who has performed the contract either wholly or in part may claim restitution from the other party of whatever the first party has supplied or paid under the contract. If both parties are bound to make restitution, they must do so concurrently.
第八十二条
（1）买方如果不可能按实际收到货物的原状归还货物，他就丧失宣告合同无效或要求卖方交付替代货物的权利。
27
（2）上一款的规定不适用于以下情况：
（a）如果不可能归还货物或不可能按实际收到货物的原状归还货物，并非由于买方的行为或不行为所造成；或者
（b）如果货物或其中一部分的毁灭或变坏，是由于按照第三十八条规定进行检验所致；或者
（c）如果货物或其中一部分，在买方发现或理应发现与合同不符以前，已为买方在正常营业过程中售出，或在正常使用过程中消费或改变。 Article 82
(1) The buyer loses the right to declare the contract avoided or to require the seller to deliver substitute goods if it is impossible for him to make restitution of the goods substantially in the condition in which he received them.
(2) The preceding paragraph does not apply:
(a) if the impossibility of making restitution of the goods or of making restitution of the goods substantially in the condition in which the buyer received them is not due to his act or omission;
(b) if the goods or part of the goods have perished or deteriorated as a result of the examination provided for in article 38; or
(c) if the goods or part of the goods have been sold in the normal course of business or have been consumed or transformed by the buyer in the course normal use before he discovered or ought to have discovered the lack of conformity.
第八十三条
买方虽然依第八十二条规定丧失宣告合同无效或要求卖方交付替代货物的权利，但是根据合同和本公约规定，他仍保有采取一切其它补救办法的权利。 Article 83
A buyer who has lost the right to declare the contract avoided or to require the seller to deliver substitute goods in accordance with article 82 retains all other remedies under the contract and this Convention.
第八十四条
（1）如果卖方有义务归还价款，他必须同时从支付价款之日起支付价款利息。 （2）在以下情况下，买方必须向卖方说明他从货物或其中一部分得到的一切利益： （a）如果他必须归还货物或其中一部分；或者
（b）如果他不可能归还全部或一部分货物，或不可能按实际收到货物的原状归还全部或一部分货物，但他已宣告合同无效或已要求卖方支付替代货物。 Article 84
(1) If the seller is bound to refund the price, he must also pay interest on it, from the date on which the price was paid.
(2) The buyer must account to the seller for all benefits which he has derived from the goods or part of them:
(a) if he must make restitution of the goods or part of them; or
(b) if it is impossible for him to make restitution of all or part of the goods or to make restitution of all or part of the goods substantially in the condition in which he received them, but he has nevertheless declared the contract avoided or required the seller to deliver substitute goods.
