Firstly, we analyze the deficiencies ofexisting ones, extend domains of fuzzy logical operators from the cap product withtwo sets to them with arbitrary (finite, enumerable, or non-enumerable) number ofsets to form two general mappings so as to conform them to the fuzzy conjunctionand infimum, and to fuzzy disjunction and supremum, respectively, and fuzzify theset inclusion of fuzzy sets. Similar to the classical adjunction, the concept of fuzzyadjunction is introduced.
首先分析了原有"模糊形态学"框架的缺陷,进而将模糊合取和模糊析取算子的定义域从两个集合的笛卡儿乘积推广到任意多个集合的笛卡儿乘积,形成两个一般的映射,使得模糊合取与下确界、模糊析取与上确界保持一致,以此将模糊集的包含关系一般化。

Database is the new database that Baidu builds to enact a new rank law, in this database in establishing a procedure, should a lot of people discover how his website didn't appear in Baidu for some time afore not the Description part of capture website, and the website of others appears in afore-mentioned phenomena, from this we can conclude it is OK that Baidu is building new B database get test and verify, the website appeared in Baidu today's phenomenon, we should OK know Baidu has been in for next rank regulation prepares, and it is important that the next will not rank influence of regard as of label of Keywords, Description will not rank influence of regard as of label of Keywords, Description regular Baidu element, even it is met throw the helve after the hatchet, turn and should do new Description to affecting the rank of website keyword with the content of own capture, corresponding do later those who optimize is difficult will increase, and Baidu will let good website appear as far as possible searching an user at the moment, so we are the following heavy name a person for a particular job meets be website oneself content to rise!
数据库算是百度为了制定一套新的排名规律而建立的新数据库,在这个数据库的建立过程中,应该有很多人在前一段时间发现怎么自己的网站没有出现在百度不抓取网站的description部分,而别人的网站出现在上述现象,从这一点上我们可以推断百度在建立新的B数据库应该可以得到验证,网站在百度中出现了今天的现象,我们就应该可以知道百度已经在为下一个排名规则做准备,而下一个排名规则百度将不会把keywords、description标签看做影响排名重要因素,甚至它会完全放弃,转而用自己抓取的内容当做新的description影响着网站关键词的排名,相应的以后做优化的难将会加大,而百度将会尽可能让好网站呈现在搜索用户眼前,那么我们以后的重点将会是网站自身内容的提高!

By synthetically analysizing the physical and chemical properties of all components and particle size, the content of F2641 in the JOB-iC is determined by gravimetric analysis after F2641 is seperated from HMX,TATB and PNP through ? alkali reflux. Determination conditions is set as follows the sample is boilingly refluxed for six hour in a constant temperature bath after adding lOOm! 8.0 ?? 0.1% NaOH. The solvent DMF saturated by TATB is used for extracting HMX,F21 and PNP from the sample and TATB is seperated by crucible filter G4. The mass precent of TATB is determined by extraction fractionation. The mass percent of PNP is measured by multiwavlength linear regression ultraviolet spectrophotometry. The testing conditions are set as follows:multiwavlength constitution: X=267nxn, 275nm, 283nm, 29mm, 299nm,the application scope of the Lambert-Beer law: the concentration of PNP is O.005?0.O25mgIml, the concentration of HMX is 0.060.3Omg/ml,absorption coefficents of PNP and HMX are solved by the slope of linear regression curve of absorbency- concentration of standard solution of PNP and HMIX for measuring wavelengthes,on the basis of the Lanibert-Beer law and absorbancy additivity principle, the slope of linear regression curve of A/E(1) and E1 of PNP and HMX solution is regarded as the concentration of PNP in the solution.
根据传爆药中各组分的物理、化学性质及主体炸药的粒度大小,进行综合分析,确定了采用碱回流重量法测定JOB-1C 中F_(2641)的含量,测定条件:加入100ml浓度为8.0±0.1%的氢氧化钠,在恒温水浴中煮沸回流6h;采用溶剂萃取法测定JOB-1C中TATB的含量,选择TATB饱和的二甲基甲酰胺为萃取溶剂,用G4坩埚式过虑器进行萃取分离;采用多波长线性回归紫外分光光度法测定JOB-1C中PNP的含量,通过实验确定了多波长组合:λ=267nm,275nm,283nm,291nm,299nm;朗波—比耳定律的适用范围为PNP浓度:0.005~0.025mg/ml,HMX浓度:0.06~0.30mg/ml;在测定波长下,对PNP、HMX标准溶液的吸光度—浓度进行线性回归,由回归曲线的斜率得出PNP、HMX的吸收系数;根据朗波—比耳定律和吸光度加和性原理,在测定波长下,对PNP、HMX 两组分混合溶液A_i/E_HMX(i与E_PNP(i/E_HMX(i进行线性回归,回归曲线的斜率即为混合溶液中PNP的浓度。

In this research, the spider silk from the major ampullate gland of native Nephila pilipes was collected via the forced-silking apparatus at the reeling speed of 3 m/min. The obtained silk was dissolved in hexafluoro-isopropanol. The influence of pH and temperature over the secondary structure of the silk protein in solution state was examined via Circular Dichroism. The effect of silk concentration and electrical field strength on the structure conformation of silk protein during film casting process was investigated via FT-IR. During the drying process, the increase of silk concentration and the presence of electric field tend to form β-sheet and β-turn. Finally, the dried film of silk protein was treated with different temperatures and cation solutions to study the post-treatment effects.

Extracts with higher antioxidant abilities, including hot water and ethanol extracts of Boehmeria nivea leaves and roots, were screened and then added into soy bean oil to study effects on oil stabilities of oxidation during storage and also to develop new XO paste products containing Boehmeria nivea leaves and roots. The extents of oil oxidation in XO paste were evaluated by measuring POV and TBA values. Results indicated that after 8 day storage at 70℃, the POV values of soy bean oil with addition of 0.1% of ethanol extracts of leaf and root were 56.27± 0.12 meq/kg and 57.13± 0.50 meq/kg respectively, which were both greater than that of control samples(53.33 ±0.31 meq/kg), showing that extracts of leaf and root do not have the abilities to inhibit oxidation of soy bean oil.
