Graphite and even its liner counterpart, poly(p-phenylene) are too insoluble . 石墨甚至其线性类似物聚苯，极不易溶解。
This graphite boat is provided with three reservoirs and a movable graphite slide . 石墨舟有三个储液器和一个可以滑动的石墨滑板。
The catalyst for this reaction is iron chromium oxide with graphite as a binder . 进行这种反应的催化剂是以石墨为粘接剂的铁铬氧化物。
Graphite and even its linear counterpart, poly(p-phenylene) are too insoluble . 石墨甚至其线性类似物，聚（名聚-苯撑）都是极难溶解的。
Graphite and even its linear counterpart, poly (p-phenylene) are too insoluble, infusible, and brittle . 石墨甚至其线性物聚苯，过于不溶，不溶和发脆。
the tube is finally heated to a temperature of about 2700℃ to atomize the sample. 最后则把石墨管加热到2700左右，使样品原子化。
The so-called "lead" in a pencil is not lead at all, but chiefly a different form of carbon called graphite . 铅笔中所谓的铅，并不是“铅”，而主要是一种不同形态的炭，称为石墨。
The allotropes of carbon include diamond, graphite and charcoal, all with the same chemical properties . 碳的同素异形体包括金刚石、石墨和木炭，所有这些物质都具有相同的化学性质。
Such small tolerances require careful design and machining of the graphite boat and slider so that the sliding motion is smooth and without jitter . 这样小的公差要求仔细设计和精心加工石墨舟皿和滑动器，从而使滑动器的滑动平滑而没有跳动。
