Results indicated that both the amount of bacteria, epiphyte and actionmyces sharply and the amounts of acarina, collembolan and nematode were increased by application of organic fertilizer and the combined application of inorganic fertilizer with organic fertilizer for a longtime. Soil animal collembolan and nematode were significantly related to soil organic material and available phosphorous and available nitrogen. Acarina was significantly related to soil organic phosphorous, available potassium and available nitrogen.

This results in a higher possibility for the components to enter the unstable demixing gap after the rapid phase separation of the system has taken place.Therefore,a bicontinuous structure is easily formed for CA membrane. For the systems of ScCO_2/toluene/PSt and ScCO_2/solvent/PVB,the increase of temperature or decrease of pressure leads to the binodal curves shifting toward the polymer/solvent axes,and thus results in the decrease of miscibility gap.The membrane toplayers of ScCO_2/solvent/PVB systems are dominated by the equilibrium thermodynamics,while the formation of membranes sublayers is the result of the combination of the equilibrium thermodynamics and membrane formation kinetics.

以下时由双节线、旋节线之间构成的亚稳互溶分相区很窄,使得该体系在快速分相后其组成变化进入旋节线内不稳分相区的可能性极高,从而易导致CA膜形成双连续结构;温度升高或压力减小均可导致ScCO_2/甲苯/PSt与ScCO_2/溶剂/PVB两种铸膜体系的双节线向聚合物/溶剂轴一侧靠近,均相区减小;ScCO_2/溶剂/PVB体系的膜表面结构形成主要受平衡热力学过程的控制,而膜的截面结构是其平衡热力学与扩散动力学共同作用的结果。

When the field is applied along the wires, the hysteresis loop exhibits a shear effect, which always means an equivalent demagnetizing field. It comes from the dipole interaction between the wires.
