  3. Sequence and large sample quality are posed. in our country or allien there are many experts who discusses some quanlity of na variable in great. for example, in documentation 6, there is a discussion about the consistency of density kernel estimation and many results have been g ained, but the density estimation f ( x ) is limited to the arrange of x [ a, 6 ] which limits the arrange of application. thus in this passage we call off this limitation and further discuss the density kernel estimation under na sample. consequently the counterpart results have been gained and the condition of result has been weaked. in the same time we discuss the density kernel estimation under pa sample and the counterpart result has been gained

    序列密度函數估計及其大樣本性質的研究課題。國內外許多專家對na變量的各種性質進行了大量的討論，其中文獻[ 6 ]曾對na樣本下密度核估計的相合性進行了討論，並取得了一些結果，但該文將密度估計f （ x ）限制在x [ a ， b ]中進行討論，這局限了應用范圍。因此本文在取消這種限制條件下對na樣本的密度核估計進行了進一步的討論，得出了相應的結果，並使結論的條件得到弱化；同時對pa樣本下的密度估計也進行了相應的討論，取得了相應的結果。
  4. The effects of poly ( vinyl alcohol ) ( pva ), poly ( vinylpyrrolidone ) ( pvp ), sodium alginate ( sa - na ) and poly ( sodium acrylate ) ( pa - na ), blended with sodium carboxymethyl cellulose ( cmc ) respectively, on the suspension stability of graphite were studied

    由於pva 、 pvp大分子的熵彈性和滲透壓效應，能改善懸浮液穩定性。 sa - na 、 pa - na還具有靜電排斥的機理，因此，比pva 、 pvp更能顯著地改善石墨懸浮液的分散性與穩定性。
  5. The dispersity and stability of the graphite aqueous suspensions was investigated with centrifugation, the violet visible spectrophotometer, the laser particle size analyzer and scanning electron microscopy ( sem ). the following aspects of the production technique were carefully studied : 1. the effects of surfactants, poly ( vinyl alcohol ) ( pva ), poly ( vinyl pyrrolidone ) ( pvp ), sodium alginate ( sa - na ) and poly ( sodium acrylate ) ( pa - na ) on the suspension stability of graphite were investigated

    本研究的主要內容有以下三個方面: 1 、研究了陰離子表面活性劑、非離子表面活性劑、聚乙烯醇（ pva ） 、聚乙烯基吡咯烷酮（ pvp ） 、海藻酸鈉（ sa - na ） 、聚丙烯酸鈉（ pa - na ）對石墨在水中分散性和穩定性的影響; 2 、研究了分散方法、分散介質、 ph值及羧甲基纖維素鈉（ cmc ）含量對石墨在水中分散性和穩定性的影響; 3 、研究了聚乙烯醇（ pva ） 、聚乙烯基吡咯烷酮（ pvp ） 、海藻酸鈉（ sa - na ） 、聚丙烯酸鈉（ pa - na ）四種助分散劑與羧甲基纖維素鈉（ cmc ）復配對石墨在水中分散性和穩定性的影響。
  6. But in more situations the random variables generating counting processes may not independent identically distributed, and in all kinds of dependent relations, negative association ( na ) and positive association ( pa ) are commonly seen. the research and apply in this aspect are rather valuable. in chap 2 we prove wald inequalities and fundamental renewal theorems of renewal counting processes generated by na sequences and pa sequences ; in chap 3 we are enlightened by cheng and wang [ 8 ], extend some results in gut and steinebach [ 7 ], obtain the precise asymptotics for renewal counting processes and depict the convergence rate and limit value of renewal counting processes precisely ; at last, in the study of na sequences, su, zhao and wang ( 1996 ) [ 9 ], lin ( 1997 ) [ 10 ] have proved the weak convergence for partial sums of stong stationary na sequences. however product sums are the generalization of partial sums and also the special condition of more general u - statistic

    但在更多的場合中，構成計數過程的隨機變量未必相互獨立，而在各種相依關系中，負相協（ na ）和正相協（ pa ）是頗為常見的關系，這方面的研究和應用也是頗有價值的，本文的第二章證明了na列和pa列構成的更新計數過程的wald不等式和基本更新定理的一些初步結果；本文的第三章則是受到cheng和wang [ 8 ]的啟發，推廣了gut和steinebach [ 7 ] ）中的一些結論，從而得到了更新計數過程在一般吸引場下的精緻漸近性，對更新計數過程的收斂速度及極限狀態進行精緻的刻畫；最後，在有關na列的研究中，蘇淳，趙林成和王岳寶（ 1996 ） 》 [ 9 ] ，林正炎（ 1997 ） [ 10 ]已經證明了強平穩na列的部分和過程的弱收斂性，而乘積和是部分和的一般化，也是更一般的u統計量的特況，它與部分和有許多密切的聯系又有一些實質性的區別，因此，本文的第四章就將討論強平穩na列的乘積和過程的弱收斂性，因為計數過程也是一種部分和，也可以構成乘積和，這個結果為研究計數過程的弱收斂性作了一些準備。
  7. Amp and adp were not significantly changed throughout the experiments, pa tended to decreased with the increases of concentrations of pollutants, nitrite - na and sodium polyphosphate could decrease atp, while methyl parathion showed a disordered atp change. aec, atp / adp and total adenylate content solely could be poor health condition markers. pa and atp are proposed as direct health condition markers of an organism to environmental stress

    整個實驗中未發現腺苷一磷酸（ amp ）和腺苷二磷酸（ adp ）有顯著變化，磷酸精氨酸隨著化合物濃度升高呈下降趨勢，亞硝酸鈉和多聚磷酸鈉能引起腺苷三磷酸（ atp ）下降，而甲基對硫磷中atp變化混亂。
