求翻译：机械活化法：Ø1.83m×6.4m的球磨机，粉煤灰试验时球磨机钢球和钢锻填充量、级配保持不变，同时保持化学活化法原料配备的成分不变。化学活化法：选取Na2S04+ Ca(OH)2矿粉复合剂，配以高效减水剂，选取Ⅲ级粉煤灰与化学外加剂的复配工艺，以不等比例掺进粉煤灰取代50%的水泥率的粉煤灰水泥胶砂内后，展开标准养护，对砂浆3d与7d的抗压与抗折强度进行测试。对机械活化及化学活化（Na2S04+ Ca(OH)2复合激发剂）对高掺量粉煤灰水泥混凝土的早期强度作用，展开研究。是什么意思？

Mechanical activation method: Ø1.83m × 6.4m ball mill, ball mill test fly ash and steel forging filler content, size distribution remains unchanged, while maintaining the chemical activation method with the composition of the same material. Chemical activation method: Select Na2S04 + Ca (OH) 2 powde

Mechanical activation method: ø1.83m×6.4m ball mill, when pulverized coal ash experiment the ball mill steel ball and the steel hammer the packing quantity, the gradation maintenance are invariable, simultaneously maintains the ingredient which chemistry activation method raw material provides to be

Mechanical activation method: ø ball mill of 1.83mx6.4m, tests of fly ash steel balls for ball mill and steel forging padding, grading remains unchanged, while maintaining the allocation of raw materials by chemical activation components unchanged. Chemical activation method: select Na2S04+Ca (OH) 2

The machinery activates the law: ØThe ball mill of 1.83m *6.4m, steel ball of the ball mill and steel forge packing amount, grade and worthy of maintaining unchanged at the time of the fly ash test, keep the composition that chemistry activates the raw materials in France and allocating not changing
