However, these advantages may be outweighed by the flow restriction the element creates in the intake line and the negative effect this has on pump life.
但是问题是滤芯会对吸入管线中流量造成限制,泵的寿命也会收到影响。

Alternatively, a dichroic filter may be used over the wavelength converting element 110 to reflect the transmitted pump light back into the wavelength converting element 110 for a second pass.
