Thispaper emphasised that the vacuoles were the characteristic of the thermally altered coals and explained the opticalproperties and geneses of the pyrolytic carbon and mesophase.
本文强调了热变煤的特征标志是孔隙的存在,并着重探讨了热变煤中新生有机组分——热解碳与小球体光性与成因,指出热解碳具有指热意义,表示近处岩体存在,而小球体及其生成的各向异性体并非表明一定有岩体存在。
Meristematic globules were induced from immature mal e flowers of 7 different banana cultivars.
以 7个香蕉品种未成熟雄花为外植体均获得了分生小球体 (meristematicglobules)。
Its mechanism is the instable mesophase sphere was formed after the pitch was heated gradually, then transforms needle cokes by coalesence.
针状焦是生产ＵＨＰ电极的重要原料，针状焦的生成机理是沥青经逐渐加温生成不稳定中间相小球体，再经堆积中间相转变为针状焦。
