Experimental results indicate that for the polystyrene particle with a larger size, Umf changes with p-0.3, and for the sand particle with a smaller size, Umf changes with p-0.21. An empirical equation about Umf is proposed based on the experimental data: Umf=μdp ρg｛［(34.15)2+0.05916×dp3 ρggμ2］12-34.15｝ It is found that the bed expansion height increases with the increasing of gas velocity, and increases with pressure for fixed value of UUmf, when the pressure exceeds 0.7MPa, the influence of pressure on the bed expansion height is weakened.

研究结果表明，大粒径聚苯乙烯颗粒的Umf与p-0.3成比例，小粒径石英砂的Umf与p-0.21成比例，并根据实验值拟合出压力下最小流化速度公式为： Umf=μdp ρg｛［(34.15)2+0.05916×dp3 ρggμ2］12-34.15｝床层膨胀高度随气速的增大而不断增高，在相同UUmf下床层膨胀高度随压力的增大而增高，在大于0.7MPa时，压力对膨胀高度的影响减弱。

On the top of the painting, the white background is infused with a few red and yellow brushworks, and thus presents its inner meaning, awe, and strength. In addition, the artist's placement of materials is never like what comprises formalism. It does not explain whether the painting is abstract or concrete. Rather, it refers to its metaphor, making the materials speak for themselves.

而在画面的上端，白色的背景有着红与黄的融渗、漫漶，深度的隐喻因此被显现出来，老虎的王气、红星的霸气、佛光的苍茫，是以内敛的张力混成的；其平面铺展并不容纳形式主义教条，不是用平面的物质真实克服视幻觉，也不是回到物象或具象本身，而是迂回到被隐喻的所指腹地，达到现象学的还原，让材料是其所是。

The production line for both three layer PE pipe and epoxy powder inner anticorrosion pipe came from the reformation of an original production line of three layer PE pipe. The main problems to have been solved are as follows, convert the conventional spray gun deflector into two parts of diversion nozzle and gun wick to suit for different pipe diameters; adopt two stage retrieval equipment to increase powder retrieval rate and improve work environment; enlarge the calibres of gas jet and Venturi pump jet to increase powder output 20% above to ensure the spry coating thickness; design gun pushing device to raise automatic production level.
