Liptinite and vitrinite convert entirely and inertinite converts partly. Unconverted inertinite can be observed hum residues. There are also scat newly formed components such as mesophase and semicoke.

结果表明，在液化过程中，原料煤中的壳质组和镜质组全部转化，惰质组部分转化，在残渣中可见未反应的惰质组，同时在残渣中出现中间相小球体和半焦等新生组分。

Don Harmony , the chief honcho at the small company making Ecospheres, was familiar with this tendency of tiny glass Gaia, and half in jest suggested that perhaps fusing an electrical ground wire onto the globe might keep the precipitates from forming.

唐·哈曼尼，那个生产生态球的小公司的大老板，对他的小型玻璃盖亚的这种倾向非常的熟悉，他半真半假地建议说，可以通过给这个球体焊上一根地线来阻止石化层的出现。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。
