判断改正：
Fiber cutting is usually considered undesirable because it results in slower drainage and loss of strength.
As refining is increased, the pulp sheet becomes more bulky because of the increased porosity.
The lower pH of the stock, the easier refining process can be made.
填料的留着是机械截留和胶体吸附综合作用的结果，并以机械截留作用为主。
填料的留着，颗粒较大的填料是靠胶体吸附作用而留着，颗粒较小的填料是靠机械截留作用而留着。
Flow controlled pressing means that the dryness increases with higher pressure.
Pressure controlled pressing means that there is a need of time to get higher dryness.
At a fixed dryness level of wet web, the roll press can produce higher bulk than shoe press.
Shoe press can generate 4 times nip width than the conventional press roll, so shoe press has more retention time in the press nip.
A increase of 10℃yields an increase 1%-point in solids content after the press nip.
