The main component of ramie glial was pectin, hemicellulose and lignin; The single factor on degumming of ramie test was respectively analyzed with a high vigorous of pectinase KDN and TZ-888 compound enzyme （mainly xylanase and mannanase on the pH value, bath ratio, dosage of enzyme, metal ions, temperature and time.The orthogonal test of L9（34 were done by bath ratio, dosage of enzyme, temperature and time. The results showed that the best compages of KDN pectinase on dry ramie degumming was 1∶12 of bath ratio,pH 8.6,1 mmol/L Mg2+,20 IU/g of KDN pectinase,4℃、4h;the best compages of TZ-888 compound enzyme on degumming was 1∶18 of bath ratio,pH 4.0,1 mmol/L Ca2+, 300 IU/g of TZ-888 compound enzyme,40 ℃,5 h.

摘 要：本研究根据苎麻胶质的主要成分为果胶、半纤维素和木质素，用高活性的KDN果胶酶和TZ-888复合酶（主要是木聚糖酶和甘露聚糖酶）从pH值、浴比、酶用量、金属离子、温度、脱胶时间等方面进行单因素试验，然后选取影响显著的浴比、酶用量、温度，时间进行四因素三水平的脱胶试验，结果表明干苎麻采用KDN果胶酶脱胶最佳组合为浴比1：12，pH 8.6， 1 mmoL/L Mg2+，酶用量200 IU/g，温度45 ℃、时间4 h时处理，TZ-888复合酶脱胶最佳组为浴比1：18，pH 4.0， 1 mmoL/L Ca2+，酶用量300 IU/g，温度40 ℃，时间5h进行脱胶为优化的试验条件。

The primary work of this paper includes: 1 The general process and the fundamental theory of genetic algorithm is introduced systematically, which is also be applied to an example; 2 The penalty function method and the constraint tournament method are introduced in the paper, which are used to process the constraint limit. Via analyzing the basic principle of NSGA-II ,which is elaborated in the paper, the fast non- dominated sorting method, congestion distance and its comparison operator, the elite strategy and the main process of NSGA-II is researched particularly. 3 Via modeling the fire distribution problem, the model is computed by the algorithm of NSGA-II, which is combined with both the penalty function method and the restraint league tournament method The optimization of two goals are also realized in the paper. The results derived from the VC++6.0 indicate that, two algorithms both have the high convergence, simultaneously the Pareto optimal solution also maintain the variety of distribution.

We have also shown that the collection of prime event structures on N can be endowed with the structure of a complete metric space, and in this space the collection of all universal homogeneous prime event structures is topologically large: it is the complement of a meager set.

我们也表明，集的主要事件结构对N可以赋予一个完整的度量空间结构，在该空间的主要活动是普遍均匀结构拓扑大：它是相辅相成的微薄的集合。

The reason of this phenomenon is studied. Continuous changes of cutting component force perpendicular to cleavage plane are found to be main causes of this phenomenon. The measurement result of machined surface microtopography by AFM is shown to be a good agreement with this viewpoint.

本文主要对该现象的产生原因进行了研究，认为车削过程中垂直解理面的切削分力的连续变化是产生这种分布特征的主要因素，用AFM对加工表面微观形貌的检测结果充分地证明了该观点的正确性。

Methods of measuring the input components, their prices and output elements are given. We put forward some new methods in measuring components, including composite depreciation rate, equality working hours, and proxy of input resources. Using the mature methods of efficiency measurement and decomposition available, we make a detailed investigation into 4 listing companies of oil industry with a span of 12 periods. Basic conclusions we draw include: labor inputs affects oil field output mostly in China; China oil fields operates in a low technical efficiency level average of 0.61; Increasing difficulties with expanding output has the greatest influence on cost; Cost efficiency of China oil fields averages at 1.47; Total factor productivity of China oil fields averages at 10%, accounting for 79% of the total output growth rate of 12.6%; Frontier technology progress contributes the most to TFP of China oil fields with 17 percentage points.

本文沿用了已有文献中关于效率计量与分解的成熟方法，对我国三家油田上市公司与一家上市石油公司12个时期的技术效率与成本效率进行了详细的计量、分解与分析，得到的基本结论有：劳动力投入是影响我国油田上市公司产出的最重要的影响因素；油田的平均技术效率仅为0.61；产出项是影响成本的显著因素，这说明随着产出增加而出现的开采难度增加是导致开采成本增加的重要因素；油田的平均成本效率为1.47；全要素生产率的增长平均在10％左右，占到了产出平均增长率12.6％的79％，表明我国油田的生产率的提高主要是依靠全要素生产率的提高而实现的，只有21％左右的产出增长是依靠要素投入而实现的；前沿技术进步是油田全要素生产率增长的主要源泉，在2001～2004年期间，前沿技术进步对油田生产率的贡献高达17个百分点。
