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。 -
The paper introduces the fundamentals of the temperature distribution in the borehole drilled in the frozen formation, and discusses the ascertainment of these parameters, including the mass quantity of circulation medium, the coefficient of thermal conductivity of drilling rods, the coefficient of the intensity of heat exchange and the coefficient of unstable heat exchange between the rock and the circulation medium, and the rising of the temperature of the circulation medium in the bottom of the bore
摘要介紹了凍土鉆孔內溫度分佈研究的理論基礎，其中主要討論了沖洗介質的質量流量、鉆桿桿壁的導熱系數、巖石同沖洗介質的熱交換強度系數與不穩定熱交換系數，以及孔底沖洗介質溫度升高值的確定。 -
On the other hand, the hydraulic performance of the hole, including flow rate coefficient and uniformity of flow rate, have been tested as standards to evaluate the quality of holes punched by laser drilling machine with much better results than that punched by mechanical drilling machine. the shape of holes taken by a microscope photograph can also give detail and well explanations for this test results
對噴孔水力學性能的試驗研究表明，本文提出的用噴孔水力學性能指標（流量系數和流量變異系數）來評價微噴帶激光打孔機質量的方法是可行的，並證明微噴帶激光打孔機的質量明顯優于機械打孔的質量，用顯微鏡觀察噴孔的形狀的照片也同樣證明了這一點。 -
This kind of shaker has such features : its self - cleaning effect is powerful, no phenomena of screen pasting and screen jam happen, when improving the treating capacity by increasing throwing coefficient, the phenomena of drilling fluids spattering can be avoided, so that screening - separating drilling fluids in closed space can be realized. hence, this new kind of shale shaker will find its application in the new drilling techniques such as under - balanced drilling
其主要特點是：自潔作用很強，沒有「篩糊」 、 「篩堵」現象；採用大拋擲指數提高振動篩處理能力時可避免鉆井液的劇烈飛濺現象；可實現在封閉的空間里進行鉆井液的篩分，因而在欠平衡鉆井等新鉆井技術的應用中也可發揮其用武之地。 -
Through comparative analysis to the test data of tow sampling methods in drilling hole and sampling method in shaft, it was found out by the author that the drilling sampling method has obvious disturbance and depression to the soil sample, which caused the soil sample ' s dry density to be increased, porosity ratio to be decreased, filtration coefficient to be decreased, and modulus of compression to be increased
筆者通過對鉆孔兩種方法獲取的土樣與豎井土樣試驗數據的對比發現，鉆孔取樣對土樣有明顯的擾動和壓密作用，造成了土的干密度增大、孔隙比減小、滲透系數降低、壓縮模量增大。
