chitosan with different stacking density is prepared in different technological conditions and process, the product must be passed the test of toxicity.
制备不同堆积密度食品级壳聚糖,可用不同的工艺条件和过程。
the porosity gradient of porous aluminium is mostly affected not only by the spontaneous stacking density of granules, but also by the infiltration pressure gradient and solidification sequence.
多孔铝合金的孔隙率梯度主要是由渗流驱动压力梯度与凝固顺序所决定,而颗粒的自然堆积密度影响相对较小。
apart from the benefits to a terminal generally associated with automating container transport, stacking and retrieval, gottwald's ascs offer far improved stacking density and faster working speeds.
高华的自动化堆积起重机不但改善了码头的自动化集装箱运输、堆积及检索效率,还提高了堆积密度,加快了工作进程。
the invention has the advantages of simple process, distinct effect, low stacking density of the obtained dried product and effectively improved product quality.
其工艺简单,效果显着,所得干燥产品的堆积密度较小,有效提 高产品质量。
