Resinite is a rich n1aceral in Teriary humic coal,boghead-cannel coal and oil shale fromHuangxian Coalfield.

黄县煤田第三纪腐殖煤、藻烛煤、油页岩显组分富含树脂体。

Humic acid had significant photosensitization on tetramethrin,and itsphotosensitization increased rapidly as the humic acid concentration increased.

腐殖对光敏化作用显著，并随腐殖浓度的增加而迅速增强。

As a result, the method of using airslake-coal to produce potassium fertilizer including humic acid was varied with different crops.

因此，在利用风化煤生产含腐植钾肥时，应根据作物类型选择工艺路线。

The new methods mainly contain the adsorption of natural materials, modification materials, humic acids, biosorption, quod of silicon micro encapsulization and nanotechnology.

主要包括天然材料、改性材料的吸附,生物吸附,技术和纳米技术等。

Experiments show that causticizing by adding a small quantity of slaked lime can eliminate the interference of carbonate ions and humic acid salts.

添加少量的熟石灰可即刻消除碳根和腐植盐等有机杂质的影响。

Humic acid is a kind of organic matter with high molecular quantity and satisfactory biological activity, and there are abundant humic acid in airslake-coal.

摘要腐植是一种有良好生物活性的有机高分子物质，风化煤中含有丰富的腐植。

Humic acid (HA ) was abstracted from leonardite,and a composite superabsorbent (HA PSA ) was prepared by compounding poly (acrylic acid ) and lignitic humic acid.

以风化褐煤为原料制备腐植(HA),将HA与普通型保水剂(PSA)复合,获得HA型保水剂(HA-PSA)。
