自由發射-
The imported transparent glaze fired at lower temperature was analysed semi - quantitatively by adopting emission spectroscope. the stripping of lead and cadmium from this transparent glaze fired at lower temperature in ceramic product was determined by atomic absorption spectroscope. the effect of chemical composition on the stripping of lead and cadmium was analysed. upon the author s opinion, the overproof lead stripping from the imported transparent glaze fired at lower temperature can only be settled by adopting lead - free glaze instead of adopting low - lead prescription. the author succeeded in developing an excellent lead - free transparent glaze fired at the lower temperature of 1000 1050. the success is based on an inquiry into the feasibility of using such new agents of fusion as li2o and sro in replacement of pbo ; and on a study of the effects of the contents of sio2 ， al2o3 ， b2o3and other metallic oxides on such performances of glaze as coefficient of linear expansion, fusion temperature and transparency. it is also based on an analysis of coefficient of linear expansion of blank and glaze on an analysis of coefficient of linear expansion of blank and glaze on their correlation ; and on a study of technology for preparing glaze

The corrosion behavior of nanocrystalline ( nc ) copper bulks with various grain sizes prepared from igc ( inert gas condemsation ) and vacuum annealing in comparison with conventional microcrystalline ( mc ) copper ( as - rolled and electrolytic ) in acid copper sulphate solution and neutral solution containing chlorides under free corrosion conditions and anodic polarizations has been studied using potentiodynamic polarization, potentiometric analysis, cyclic voltammetry and electrochemical impedance spectroscopy. x - ray diffraction was used to estimate the grain size of the annealed nc copper. field emission gun scanning electron microscopy and x - ray energy - dispersive spectroscopy was used to characterize the surface morphology and analyze the surface composition after the polarization and potentiometric test of both nc and mc copper
本文研究了用igc （惰性氣體蒸發凝聚原位溫壓法）制備並真空退火到不同晶粒尺寸的納米晶銅和微米晶銅（冷軋紫銅、電解銅）在酸性硫酸銅溶液和中性含氯溶液中，在自腐蝕狀態和陽極極化狀態下的腐蝕性能。使用了動電勢極化、電位測定、循環伏安法（ cv ）和電化學阻抗譜（ eis ）等方法。 x -射線衍射（ xrd ）的方法用來估算納米晶銅晶粒尺寸。 -
The tea waste powder with different sizes as an additive was used to urea - formaldehyde ( uf ) resin, and the effects of the tea waste powder sizes and amount on the free formaldehyde content of uf resin, the formaldehyde emission, and hood strength of uf resin hooded plywood were studied in this paper
摘要將不同顆粒度的茶葉廢料粉添加到脲醛樹脂膠中，研究了茶葉廢料的顆粒度、加入量等對脲醛樹脂膠黏劑的游離甲醛含量、黏接膠合板的甲醛釋放量及膠合強度的影響。 -
The experimental results indicated that the tea waste powder as an additive to uf resin could reduce its free formaldehyde content and reduce the formaldehyde emission of uf resin bonded plywood ; the tea waste powder with much less size was easily mixed with uf resin and acted much more effective ; the tea waste as an additive to uf resin in a proper amount did nut decrease the bond strength of plywood
實驗結果表明，茶葉廢料作為填料添加到脲醛樹脂膠黏劑中，能夠降低其游離甲醛含量以及其黏接膠合板的甲醛釋放量；茶葉廢料顆粒度越小，與脲醛樹脂混合性越好，消除甲醛效果越顯著；茶葉廢料的適量加入不會降低膠合板膠合強度。 -

The fluorescence spectrum ( fls ) of lra excited at 280nm and 295nm showed a maximum peak at 338nm. the characteristic peak of tyr did not exist, and it showed that the fluorescence energy of tyr was transformed to trp and strength the fluorescence of trp. when lra was excited at 295nm, the fls showed a maximum peak at 338nm, the max of fluorescence emission spectrum blue - shifted more than 10nm compared with the max of free tyr ( 348nm )
Lra的熒光光譜研究表明在激發光波長為280nm時，其最大熒光發射峰在338nm處，熒光光譜未見有酪氨酸（ tyr ）殘基的發射峰，表明tyr殘基的熒光基本上通過能量轉移到trp上，使熒光強度增強，在激發光譜為295nm時，其最大熒光發射峰338nm ，比游離trp的最大熒光發射峰（ 348lun ）藍移了近10nln ，說明trp周圍的極性較弱，處于疏水的微環境。 -
