The second desideratum, of low thermal and high electrical conductivity, was achieved by dividing the bismuth telluride into pellets a few nanometres across.(第二個所愿望之物——低熱量和高導(dǎo)電性，是通過將整個鉍碲劃分成幾個納米顆粒實(shí)現(xiàn)的。)

This would be fine if zero regulation were the social desideratum, but it is not.(如果零管制是社會需要的那將很好，但并不是這樣。)

Not a bad fraction of the desideratum, but one that will be hard to sustain in the face of the world's economic difficulties.(與總需求相比這還不算太糟，但在全球經(jīng)濟(jì)面臨困境的當(dāng)下，想維持這一水平卻又是個難題。)

If it can be dealt with, that will be a huge step towards the ultimate desideratum of HIV research-a simple and effective cure.(如果這些問題解決了，那么就會朝向艾滋病研究的終極目標(biāo)，即簡單有效地治愈艾滋病，又前進(jìn)了一大步。)
