aerogel n.氣凝膠。

Here we use robotically - controlled micromanipulators and extremely sharp glass needles to machine the aerogel , and extract tracks in tiny doorstop - shaped wedges of aerogel that we call “ keystones “ 在此我們用自動控制的顯微操作器和極其尖銳的玻璃針來加工氣凝膠,并取出含有軌跡的一小塊楔形凝膠,我們稱之為“楔石” 。

Q . what is an aerogel “ movie “ 問:氣凝膠“影片”是什么?

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 試驗是在飛行備用的碟子上進行的,首先在打開襯托前做一張聚焦圖(在一個格子里取200個點測量凝膠塊的高度) ,打開后再作一次。

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“宇宙塵埃實驗室”我們已經掃描了超過10個氣凝膠塊,并新近編寫了一個程序用來對迄今為止得到的4萬個聚焦影片進行逐一檢查。

The specific capacitance of speudo - capacitor is about 10 - 100times of the double - layer capacitor . the compound carbon aerogel is elected as electrode materials of the pseudo - capacitor in this thesis 本次試驗選定復合碳氣凝膠作為贗電容器的電極材料,其中碳氣凝膠采用新型超臨界干燥設備獲得,并用賤金屬氧化物nio與之復合。

With the development of the sol - gel process the crazing problem in the bulk of aerogel has been settled . silica gels were provided with even far - reaching applications foreground 尤其是近年來隨著溶膠?凝膠科學技術的興起和飛速發展,大塊氣凝膠制備的難點?開裂問題已經被解決,使得sio _ 2凝膠具有了更為深遠的應用前景。

Here we use robotically - controlled micromanipulators and extremely sharp glass needles to machine the aerogel , and extract tracks in tiny doorstop - shaped wedges of aerogel that we call “ keystones “ 在此我們用自動控制的顯微操作器和極其尖銳的玻璃針來加工氣凝膠,并取出含有軌跡的一小塊楔形凝膠,我們稱之為“楔石” 。

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 如果出現這種情況那將是個問題,因為我們依靠凝膠塊的穩固性來重建彈道,并由此區分星際塵埃和太陽系內塵埃。

We do have a flight spare that we could practice with , but we know from our experience with the cometary aerogel that it has changed somewhat in space ; it has become more brittle 我們確實有大量可供練習的備用品,但是我們從彗星塵埃的凝膠那里得到的經驗是:凝膠在太空里發生了一些變化,變得更加易碎了。

Here ' s how it will work : as in the original plan , the automated microscope will scan the entire surface of the collector , recording digital images of each miniscule portion of the aerogel 它是這樣工作的:與先前的計劃一樣,自動顯微鏡將掃描收集器的整個表面,記錄下氣凝膠每一細微局部的數字影像。

2 . a composite electrode material comprising carbon aerogel and nickel oxide is obtained by coated nickel oxide on carbon aerogel and heat - treatment in air . the structure and electrode performance are studied 2 .應用sol - gel法在碳氣凝膠表面沉積氧化鎳,熱處理后制成電極,研究了其結構和電性能。

These particles , furthermore , are embedded in about 1 , 000 square centimeters ( more than a square foot ) of aerogel , which after years in space is likely to be crisscrossed with cracks and flaws 此外、這些顆粒深植在1000平方厘米的氣凝膠中,經過數年的太空飛行氣凝膠很可能布滿交錯的裂痕和缺陷。

We are using this temporary hold up in scanning as an opportunity to install and test new hardware on the microscope that will enable us to extract candidates from the aerogel for analysis 利用掃描暫停的機會我們安裝、測試了顯微鏡上的新設備,它將使我們能把候選者從凝膠中取出進行分析。

As we mentioned in the march 27th update we are planning to extract candidate tracks identified by stardust @ home volunteers from the aerogel collector directly for analysis 如同在3月27日的更新中提到的我們正在計劃從寧教授機器中提取出由志愿者識別出的軌跡直接用于分析。

We are uploading data from one newly scanned aerogel tile today , with another four tiles currently being processed . we produce about 4000 new focus movies each day 今天我們上傳了一塊新掃描的凝膠塊的數據,同時還有4塊的數據正在處理中。我們每天會產生大約4000部新片子。

First , because the aerogel may be somewhat distorted during extraction , we may partially lose the ability to accurately determine where on the sky the particle originated 首先,凝膠在取出時可能會受到一些損壞,將使我們部分的喪失測定微利來自天空的哪個方向的能力。

When a hypervelocity particle enters the top surface of an aerogel collector , it makes a track many times its own size as it slows and stops in the aerogel 當一個超高速微粒進入氣凝膠收集器的頂部表面時,它會減速并停在氣凝膠內部并制造一個比自身大許多倍的軌跡。

When a hypervelocity particle enters the top surface of an aerogel collector , it makes a track many times its own size as it slows and stops in the aerogel 當一個超音速微粒進入氣溶膠收集器的上表面時,隨著減速它將造成一個數倍于自身大小的軌跡并停留在氣溶膠中。

The transmitted light has already been reinstalled in the microscope , but we have to confirm that we can reliably and safely fold back the foils holding the aerogel tiles in place 透射燈已經重新裝入顯微鏡,但是我們必須確保能安全可靠的去掉拖著凝膠塊的擋板。
