If it does this could be a problem , since we rely on the stability of the aerogel tiles to be able to reconstruct trajectories , and thus distinguish betwen interstellar dust and interplanetary dust 如果出现这种情况那将是个问题，因为我们依靠凝胶块的稳固性来重建弹道，并由此区分星际尘埃和太阳系内尘埃。
We have scanned more than 10 aerogel tiles in the cosmic dust lab in houston and have recently written a computer program that checks the focus on each of the 40 , 000 focus movies we have so far 在休斯敦的“宇宙尘埃实验室”我们已经扫描了超过10个气凝胶块，并新近编写了一个程序用来对迄今为止得到的4万个聚焦影片进行逐一检查。
This test was done on the flight spare tray by first making a focus map ( a measurement of the altitude of the aerogel tile at about 200 points on a grid ) before unfolding the foil , then doing it again after 试验是在飞行备用的碟子上进行的，首先在打开衬托前做一张聚焦图（在一个格子里取200个点测量凝胶块的高度） ，打开后再作一次。
We want to unfold the foils so that we can examine and image the tiles using transmitted illumination ( light from below the tile ) rather than reflected illumination ( light through the microscope objective lens ) 我们打算打开衬板这样就能用透射光（光线从凝胶块下面照过来）而不是反射光（光线从显微镜物镜处照过去）照明来对凝胶块进行检查、拍照。
The idea is to use a micromanipulator mounted on the side of the stardust interstellar collector tray to extract keystones ( tiny wedge - shaped sections of aerogel surrounding a track ) directly from aerogel tiles while still in the tray 想法就是用安置在星尘收集盘边缘的一台显微操作设备从还待在盘中的凝胶块里直接直接提取关键部分（一小块围绕着一个轨迹的楔形凝胶） 。
The mysterious pyramid performs result : use the transparent pyramid to a square box for seal completely to cover , borrow again to come to audience to write up the coin of the mark , put the appointed position of the gum piece outside pyramid . then cover pyramid with the handkerchief , give sorcery . while openning again handkerchief , the coin is disheveled hair now the square box of the pyramid inside 表演效果：把一个密封的方盒用透明金字塔盖着，再借来观众写上记号的硬币，放在金字塔外胶块上的指定位置。然后用手帕把金字塔盖着，施以魔法。当再打开手帕时，钱币被发现在金字塔的方盒内。
