当你谈及人们的时候，以什么人为参照物？

"Whom are you referring to when you speak of people"?

也就是说，所谓现场的写生，对他而言也只是提供了一个参照物和刺激而已。

That is to say, the onsite painting from life or nature provides a reference or stimulus to him.

蚊香的支架，又是调节、和控制燃烧时间的参照物，并可保持香灰的原始形态。

Mosquito coil stand, reference for adjust and control the burning time, also keep the coil ash original Patten.

在这一步上我们需要充分的考虑，因为你没有参照物来确定这个平面在现实中究竟是怎样的。

There is an entire discussion here, because you can’t define that plane exactly how it is in reality since you have no reference.

猫和狗的基因组计划的长足进步，使猫和狗的基因组成为食肉目动物比较基因组研究理想的参照物。
