    Abstract: C-P cell為一量測濾餅之空隙率及過濾比阻的重要裝置,但因有器壁摩擦效應,而導致應力傳遞損失及結構不均勻的現象。本研究分別採用由濾餅之對數平均應力P/sub lm/以及由彈性力學解析之平均應力P/sub s/來估計濾餅固體壓縮壓力P/sub s/,再分別探討各種粉體在不同機械應力下之應力、空隙度及過濾比阻的修正幅度,並應用此修正後之.epsilon.及.alpha.對 P/sub s/的關係,來模擬實際的恆壓過濾結果,對硅藻土、碳酸鈣、高嶺土及皂土等的模擬結果指出,未經過修正的壓縮透過數據對恆壓過濾的模擬產生約-8.sim.-48%的偏差,而經應力解析修正之壓縮透過數據對恆壓過濾模擬的偏差僅在-2.02-11.4%。
