general porosity 中文意思是什麼
general porosity
解釋
總孔隙度-
In general, smaller grain size and greater angularity tend to increase the porosity while an increase in range of particle size tends to decrease porosity
通常，顆粒越小曲率越大孔隙度越大，而當顆粒尺寸增大時孔隙度會減小。 -
The investigation of a lot of parameters about treated sandstone, brick materials and earthen materials with fluorited polymers has been carried out, such as the formation of polymer, the penetration depth, porosity, capillary absorption and penetration coefficient, water uptake, compressive strength, drilling resistance, absorption isotherms of water vapor, water vapor diffusion, color changes as well as resistance to desegregation of water, frizzing - throwing cycles, worming - cooling cycles, and so on. in addition, the influence of salt crystallization, acid and base, and uv aging have also been assessed in order to better understand the protection effects and utilization possibility of two fluorinated polymers, mainly according to astm standard and the combination of international methods together with general technological
分別以國家級文物保護單位的土質、砂巖和磚材文物樣品為對象，依據astm標準及國際通用文物保護研究方法與評估準則相結合，通過膠化物形成周期、滲透深度、孔隙度、毛細吸水和滲透系數、持水量、抗壓強度、抗鉆強度、吸附水蒸氣的能力、透氣性、外觀顏色等系列參數的測定，及凍融、冷熱循環、酸堿腐蝕后抗壓強度的衰減、可溶鹽對保護效果的影響、酸堿及光照對表面保護效果的影響，對兩種含氟聚合物及其與有機硅的共混物在文物加固保護和表面防護中的可行性和保護效果給予了系統研究。 -
