- When a sand-carrying blast loses 20% of its velocity in front of and behind the net,the sand grains carried will fall one after another,terminating its risky travel. 當運載著(zhù)沙塵的疾風(fēng)在網(wǎng)前網(wǎng)后失掉20%25的速度時(shí)，所攜帶的沙粒便紛紛墜落，終止了它們危險的旅行。
- On this scale the moon would be scarcely more than a dust speck about 1cm from the sand grain. 照這樣的比例尺度，月球將是僅離小沙粒一厘米遠的一顆尖埃微粒。
- When a sand-carrying blast loses 20% of its velocity in front of and behind the net, the sand grains carried will fall one after another, terminating its risky travel. 當運載著(zhù)沙塵的疾風(fēng)在網(wǎng)前網(wǎng)后失掉20%25的速度時(shí)，所攜帶的沙粒便紛紛墜落，終止了它們危險的旅行。
- With high magnification of microscopy,a lot of petroleum inclusions were found,which occur in the fissures of sand grains and authigenic minerals in the source rock. 用高倍熒光顯微鏡觀(guān)察,在這些暗色泥巖的砂質(zhì)碎屑礦物和自生礦物中,發(fā)現豐富的微石油包裹體群。
- For thermally reclaimed molding sand due to its low angularity and improved shape, more, larger area and stronger bonding-bridges are easily formed among sand grains. 熱再生砂的角形系數降低,粒形得到了改善,砂粒之間更易形成較多、較大的粘結橋;
- A tenebrionid beetle, Onymacris rugatipennis, it buried itself one moment and then rushed forth again, as if skating along the surface of infinite sand grains. 我們還看見(jiàn)一種擬步行蟲(chóng)（Onymacrisrugatipennis）一下子把自己埋進(jìn)沙地，一下子又向前沖，好像在無(wú)垠的沙地上溜冰，動(dòng)作之快，我幾乎來(lái)不及搶拍牠的模樣。
