查询词典 apertures

The process produces extremely precise, smooth-walled apertures with a natural taper that require no additional finishing processes.

和化学腐蚀及激光切割相比，电铸是一个附加工艺，电铸钢网是用电镀材料，通常为镍，在带负电孔型成像的卷筒，该工艺能形成精确光滑表面的孔，自然锥度另需精加工。

In contrast to chemical etching and laser cutting, electroforming is an additive process. Electroformed stencils are "grown" by electro-depositing a plating material, usually nickel, onto a mandrel carrying a negative, photo-resist image of the aperture pattern. The process produces extremely precise, smooth-walled apertures with a natural taper that require no additional finishing processes.

和化学腐蚀及激光切割相比，电铸是一个附加工艺，电铸钢网是用电镀材料，通常为镍，在带负电孔型成像的卷筒，该工艺能形成精确光滑表面的孔，自然锥度另需精加工。

It is because through the apertures the exterior electromagnetic field will couple with the cavity, and excite resonance in the cavity.

甚至在空腔中特定位置有著比无屏蔽时更大的场，对於封装内的电路构成额外的干扰。

This is a subtractive process that uses photolithographic techniques to define the aperture pattern, and then applies an etchant to form the apertures simultaneously from both sides of the stencil.

过去，普遍采用的低成本的钢网制作方法是化学腐蚀。

Critics also point out that neither of the rear sight apertures is ideally sized.

当新的型号被认为更精确的时候，更重的子弹也带来了更弯曲的弹道曲线，从而使得距离估量的准确性要求更加高。

In pollen grains, these apertures may be only thin spots rather than actual perforations.

在花粉粒中，这些孔可能仅仅是薄的区域，而不是真正的穿孔。

Hanna: That's over now, isn't it?

都结束了，对吗

You must be ill. You look so pale.

你一定是病了，你的脸色苍白。
