當(dāng)弗蘭茲又回到岸邊的時(shí)候，那艘游艇已經(jīng)象是地平線上的一個(gè)小白點(diǎn)了。
On the basis of experiments, two kinds of butt joint forming physical models and three types of dimple models of fractography have been proposed. These models reveal the essence of welding process and the forming mechanism of white speck.
在試驗(yàn)研究的基礎(chǔ)上,提出了兩種形式的接頭形成物理模型和3種類型的接頭斷口韌窩模型,由此可揭示接頭的形成木質(zhì)和“白斑”形成機(jī)制。
However, the so called white speck, as sometimes appeared on the fractography of the checked sample weld, may lead to fracture or burst of steam pipes during high temperature operation.
但在抽檢樣品時(shí)接頭斷口上有時(shí)存在所謂的“白斑”組織。“白斑”的存在可導(dǎo)致蒸汽管在高溫運(yùn)行時(shí)發(fā)生破裂或爆管。
Meanwhile, optimizing selection of process parameters are made to reduce fibre white specks.
同時(shí)，對(duì)減少纖維泛白的工藝參數(shù)，進(jìn)行了優(yōu)化選擇。
Photographs of the test scoop showed white specks in the soil, which could be salt or ice.
在回傳的照片上，探測(cè)掘鏟上可以看到有土壤里有白色的斑點(diǎn)，它們可能是鹽或者是冰。
