Dynamic weighing system is as a second - order system and set it up model, then has its transform function laplace transform and z transform, at last has a formula that m is only relation to the system parameters. this article has system identified with the recursive least square ( rls ) method, and has the system parameters, while the auto - regressive - moving - average ( arma ) model for the second order weighing system is firstly derived. and has a equation which the mass is only correlation to the system parameters
論文具體分析了定量稱量問題，首先是把稱量系統看作是一個二階系統，建立數學模后，進行拉普拉斯變換和z變換后得出一個質量僅與系統參數有關的關系式，從而把稱量問題轉化為一個系統參數識別問題來解決。通過編寫的程序來採集系統信號並進行處理（運用漸消遞推最小二乘法）對系統參數進行識別，從而得出稱量結果。 -
In order to study the direct relation between oil - base drilling fluid performance and cement job quality, a new developed evaluation method ( artificial core method ) was adopted ; the effects of the oil - base drilling fluid system and its main components on the shear cementing strengths of the first and second interfaces in cementing operation were investigated ; and those of the different mix slurry ratios on the gel strength, initial set time, final set time of slurry and the compressive strength of bond cement were examined too
摘要為了研究油基鉆井液性能和固井質量之間的直接關系，採用新建立的評價方法人工巖心法，考察了油基鉆井液體系及其主要組分對固井作業中第一、第二界面剪切膠結強度的影響規律，以及不同混漿比例下對水泥漿膠凝強度、初凝時間、終凝時間和水泥石抗壓強度的影響規律。 -
In order to study the photochemical activity of the product further, this dissertation, taking methyl orange as a deputy of organism, has studied the relation between the concentration of the organism and the reactive time during the process of light degradation, and, on the basis of the relation, the kinetic process of the photocatalytic degradation was achieved by the treatment on the curve of the organism concentration to the reactive time : zero order reaction of the high organism concentration, first order reaction of the middle organism concentration, second order reaction of the low organism concentration
在產品對有機物的光降解方面，本文主要以產品光降解甲基橙溶液為例，研究了光降解過程中，有機物濃度與時間的關系。並在此基礎上，對有機物濃度與時間的曲線進行了動力學處理，得出產品光降解甲基橙的動力學過程分為三步，摘要即:高濃度時的零級反應、中等濃度時的二級反應和低濃度時的一級反應。 -
According to the relation between tangent space and annihilation space of parameterization singularity manifolds, we present the new concepts of first order and second order singularity. degenerate and non - degenerate parameterization singularities are analyzed and the sufficient and necessary conditions for degenerate singularity are derived
研究了退化和非退化奇異位形的特點，給出了判斷退化參數化奇異位形的充分和必要條件，其中對必要條件，提出了一種方便實用的morse判斷函數。 -
