The main results are following : ( 1 ) the variation of clay / silt ratio can indicate the secondary clay action of dust depositions ; the variations of magnetic susceptibility and total fe content are inferred to be records of the changeable intensity of bio - pedogenesis ; the variations of sr content and rb / sr ratio can indicate bio - pedogenesis, dissolving and leaching action ; the content of total organic carbon ( toc ) can reflect variation of climate and vegetation during soil formation, it indicates the intensity of weathering and bio - pedogenesis ; the content variation of caco3 can show the intensity of dissolving - leaching action and secondary deposit, which was noted as pseudomycilia in pores and fissures in the sediment, so it can indicate the intensity bio - pedogenesis quite well. these proxy indexes also reflect obvious regional difference of pedogenic environment and the intensity bio - pedogenesis ; namely, secondary clay action, dissolving - leaching action and bio - pedogenesis are all much stronger in south than that in north
實驗結果表明：粘粒粉沙比值能很好地指示粉塵堆積物的次生粘化作用；磁化率和全鐵很好地指示生物風化成壤作用； sr和rb sr比值能很好的指示生物風化成壤作用和淋溶作用；總有機碳（ toc ）含量的高低，在一定程度上反應了土壤發育過程中氣候和植被狀況的變化，指示著成壤過程中腐殖質化的程度； caco3含量的變化，可以反映了黃土古土壤形成時的風化成壤作用的強弱程度，指示成壤過程中的淋溶作用和次生碳酸鹽化作用；並且各指標所指示的成壤環境和成壤強度存在明顯的區域差異，即渭河流域土壤的生物風化成壤作用、次生粘化作用和淋溶作用均表現出南部強于北部。The results indicated that the dimension, shape and purity of base material could meet the functional demand of solid lubricant ; the thermal decomposition temperature of ptfe resin exceeds 400 c, but organic and inorganic packing filler added in ptfe made the water absorption rate of composite material increased, melting temperature and decomposition temperature decreased, in the meanwhile oxidative decomposition reaction was accompanied ; polar groups such as c = o, c - o - c and so on in the carbon fiber surface is advantageous to increase compatibility with other components and interlayer shearing strength ; uniform design experimental method could help to find the relationship between formula and frictional property by relatively small tests. the developing trend of each formula ' s friction coefficient could be showed by fitting curve ; the friction coefficient with no copper powder or graphite in formula was relatively big. this fact showed that copper powder and graphite should be used cooperatively ; it was found that when the ratio of copper powder to graphite by weight is 15 : 60, 30 : 30 - 40 and 60 : 15 - 30 respectively, the friction coefficient was relatively small. the degree of crystallinity of pure ptfe reached maximum by air cooling and the abrasion loss also reached maximum among three ones ; at the same time, the abrasion loss of solid lubricant sample was also the biggest among three ones ; when solid lubricant matched with 45 # steel axle or gcrl5 steel axle, lubricant transfer film could be formed on metal surface, thus direct contact between the surface of metal friction pair rings was reduced. their working life was elongated extremely ; there was mainly much graphite, a little ptff, moo3, feso4, cus and so on in lubricant transfer film

氮肥用量不足導致穗葉葉肉細胞葉綠體結構性差，維管束鞘細胞碳水化合物累積減少，營養體氮素再分配率大而引起葉片早衰；而過量供氮則導致生長後期硝酸還原酶活性過高，氮素代謝過旺，消耗了大量碳水化合物，以致下位葉不能得到充足的碳水化合物供應而提早脫落，同時葉肉細胞葉綠體片層結構膨脹，呈「肉汁化」特徵，維管束鞘細胞澱粉粒大量消耗，無核澱粉粒出現，從而葉片葉綠素含量下降，光合能力降低而出現早衰。Using this system, research on nox emission and burnout characters of the test facility are carried out. the results of influence on nox emission and carbon in fly ash by coal type, coal particle diameter, furnace temperature and excess air are reached through tests. then micronized coal reburning tests are processed, which show a remarkable effect results on nox reduction and burnout rate
