The so-called "lead" in a pencil is not lead at all, but chiefly a different form of carbon called graphite . 鉛筆中所謂的鉛,并不是“鉛”,而主要是一種不同形態(tài)的炭,稱為石墨。
The allotropes of carbon include diamond, graphite and charcoal, all with the same chemical properties . 碳的同素異形體包括金剛石、石墨和木炭,所有這些物質(zhì)都具有相同的化學(xué)性質(zhì)。
Such small tolerances require careful design and machining of the graphite boat and slider so that the sliding motion is smooth and without jitter . 這樣小的公差要求仔細(xì)設(shè)計(jì)和精心加工石墨舟皿和滑動(dòng)器,從而使滑動(dòng)器的滑動(dòng)平滑而沒(méi)有跳動(dòng)。
