While numerical modelling of surface travelling wave absorption performance was feasible, without experimental data, calibration of any such simulation model was not possible.

即便没有试验数据，表面行波吸收性能的数值也是可以模拟的，但是不能校准这些模拟数值。

At this time the simulator does not implement surface travelling wave modelling and associated edge or gap backscatter modelling, or edge diffraction scattering effect modelling.

这次模拟器没有对表面行波、相邻边界和缝隙的反向散射，或者边缘绕射散射效应进行建模。

No effort was made to assess the performance of the surveyed materials as surface travelling wave absorbers.

评估表明，把被研究材料作为表面行波吸收剂是不可行的。

Based in Washington state, Terrapower is working on a design for what is known as a travelling wave reactor.

Moreover, in fields like solar cells, travelling-wave tubes and read-out integrated circuits, there is either only one domestic supplier or a financially weak supplier.
