各位好，请问一下我想表达下列句子:
所有验证都在我们的实验室里执行，请问用下面哪个句子比较正确?
1. All verifications were performed in our lab.
2. All verifications were performed by our lab.
3. All verifications were completed in our lab.
4. All verifications were completed by our lab.
感谢各位

在你们实验室不代表就是你们实验室的人做的，执行的验证不代表完成了。我推1

1+1

一楼很有说服力

所有验证都＿1＿我们的实验室＿2＿1. 完成／执行...对不起打错1. 在／由2. 完成／执行在我看来，四种组合大同小异。除非是那种讲了有法律责任一定要很精确的声明稿...

1 符合你中文语意。 若 英2语意，翻回中文会是由我们实验单位负责执行 (人)
