But DuBois says that because other researchers in the field now have a good examples of systems that work, they can now focus on designing improved catalysts to speed them up.

但是DuBois之所以那样说是因为，在这个领域的其他研究人员，现在有了这方面的系统化的范例，现在他们可以专注于设计更好的催化剂来加速他们的研究了。

Sequence information can have practical significance - for example, in designing PCR primers, to make rapid diagnosis tests that broaden and speed up surveillance.

序列信息具有实际意义-如，通过设计PCR引物，我们可以快速对这种病毒做出诊断，从而扩宽和加快监控。

Dai and the Sutardjas next went after networking products, designing a chip that would transmit data through Ethernet ports at a billion bits per second, ten times the speed of the then current standard.
