The fabrication processes for nano-silicon-tips using a (100) single crystal silicon wafer by the anisotropic wet etching in the KOH etchant were designed. Based on the experiment and the model of {411} crystal planes, the crystal planes of silicon tips were analyzed. Through discussing the effect of the mask direction on tip shapes, the process parameters to get high aspect ratio nano-silicon-tips were achieved.

Reedy尖聲的:Her voice is so reedy.

她的聲音很尖

According to the following drawing , it can be made a distribution. Why the breath application of Hulusi and Bawu is so especial. The explanation of voice reed can help to understand. Now, let's look at the key part of Hulusi and Bawu ,which be magnified and is a reed model . The libration come into being by the middle part that like the bird tongue, which librate and sound wave come into being. Its character is that the part ——from head to end broaden step by step, the head is narrow and the end is wider than the head. So, we can catch on that the end libration decide the bass pronunciation for the end is wider and it need more strong air while it librate, the libration of acuate part decide the high pronuciation for the acuate part is acuate and it needn't more strong air while it librate.
