对于损失的恐惧相对于利得的前景（这种方法也有效，但是效用不如前者）来说，是更有利的激发因素。

The fear of loss was a better motivator than the prospect of gain (which worked too, but less well).

斯特拉诺小组现在正致力于研究如何将激子从纳米纤维的一层游弋到另一层时所带来的能量损失降到最小，和如何能够使一个光子可以激发不止一对激子。

Strano's team is now working on ways to minimize the energy lost as excitons flow through the fiber, and on ways to generate more than one exciton per photon.

此装置可用于研究荧光寿命、激发函数、电子能量损失谱和分子解离过程。

The apparatus can be used to measure the lifetime of fluorescence segment, electron excitation function, electron energy loss spectra and molecular dissociative processes.
