比例分布

Results during 2003-2006,202 afp cases were reported in linyi city,no wild poliovirus was detected.these afp cases were distributed in 12 countries.the age of afp cases was mainly 0-5 years old,accounting for 83.2%,higher incidence in male than in female,the rate is 1.93:1.all afp cases were discarded poliomyelitis cases by the diagnoses group of shandong province.the rate of guillain-barre syndromein these cases was 19.9% monitored and has appraised 3 cases of vapp.the reported incidence of non-polio afp cases of children under 15 years old has been over 1/100000 since 2003.other indexes have been above 80%.

结果 2003～2006年全市共报告afp病例202例，未发现脊灰野病毒引起的病例。病例分布在全市12个县：发病以0到5岁儿童为主，占83.2%；男性发病多于女性，男女比例1.93：1；所有监测病例经山东省专家诊断组均为排除脊灰病例，格林巴利综合征最多，占19.9%，监测并鉴定了3例疫苗相关病例。

The simulation results show that staged air can significantly reduce tangential circle diameter of upper parts of furnace and lower heat transfer difference of horizontal gas flue; the field test results show that the proper ratio of staged air in the total air can make tubes wall temperature distribution of high-temperature superheater uniform, and tubes' peak temperature lowered 5~10℃.

模拟计算结果表明炉内分级送风对于减小炉膛上部切圆直径、降低水平烟道内的热偏差作用明显；现场试验结果表明，适度增大炉内分级送风比例使高温过热器管壁温度分布更均衡，峰值温度降低5～10℃，使受热面运行安全性得以提高。

The molecular weight and molecular weight distribution of polyethylene were determined by GPC and Viscometry.

对GPC曲线的高斯函数拟合分峰，计算在双组分茂金属催化体系中每种催化剂得到的聚乙烯的重量之比；根据各催化剂的催化活性和按所加的催化剂的摩尔比例假定进行独立反应时，可以计算在双组分催化体系中每种催化剂得到的聚乙烯的重量之比；根据两种重量之比的比较结果和对双组分茂金属催化体系得到的聚乙烯的平均分子量和平均分子量分布的分析结果，可以推测在催化体系CatZr〓/CatZr〓中两种催化剂基本上不存在相互作用；而在CatZr〓／CatZr〓体系中两种催化剂之间可能有相互作用存在。

The experimental results of stepwise ethanol precipitation showed that the yeild represents the increasing trend with increase of the ethanol concentration, their polysaccharides contents have significant changes, and at the ethanol concentration of 30% and 70%, polysaccharides contents are up to maximum. Molecular weights of endopolysaccharides and exopolysaccharides are pockety.

分级醇沉实验表明，各醇沉浓度对应的得率都随醇浓度的升高而呈增加趋势，多糖含量变化起伏较大，醇浓度为30%和70%时所得多糖含量较高，虫草胞内和胞外多糖分子量分布都很不均匀；分步醇沉测定了各部分多糖所占的比例。

The method comprises the steps of dipping and mixing the mipor asphaltic base globular active carbon prepared by the traditional method with an inorganic metal salt solution by a certain ration; heating under an inert atmosphere to 600 to 1200 DEG C at a temperature increasing rate of 1 to 20 DEG C/min for the secondary carbonization; using acid to wash off the remaining metal inside the carbonized material, so as to obtain the asphaltic base globular active carbon with a high mesoporous rate and narrow distribution of mesoporous spertures.

本发明提供了一种浸渍金属盐二次炭化制备中孔沥青基球形活性炭的方法，该方法是将传统方法制备得到的微孔沥青基球形活性炭按一定比例与无机金属盐溶液浸渍混合，然后在惰性气氛下以1～20℃/min的升温速率加热到600～1200℃下进行二次炭化，炭化料经酸洗除去内部残留的金属后，可制得中孔率较高、中孔孔径分布窄的沥青基球形活性炭。

Objective To master the changes of distribution and tendency of drug-resistance of Z-H bacilli in recent 8 years in our city.

目的研究我市志贺氏菌菌群8年来在分布比例上的变化情况及抗生素耐药性变化趋势。

Results The 4 spectrums distribution of this bacilli has not changed and the drug-resistance tended to be increased gradually in clinic.

结果志贺氏菌的4种菌群在分布比例上未发生明显变化，志贺氏菌对临床常用抗菌药物的耐药性有逐步增加的趋势。

Methods 12 guinea pigs of 20 months with 3 cm×3 cm hair sheared from their backs were divided into control group and experimental group. Rhodosin and deer serum preparation was besmeared on the skin of guinea pigs in experimental group, and cosmetic matrix was besmeared on the skin of animals in control group for 60 d. The distribution of type Ⅲ collagen was observed with Sirius red staining and HE staining. The fission index of the cells of stratum basale, the thickness proportion of stratum corneum to epidermis, the volume density of the collagen fibers and small blood vessel in dermis, the number of fibroblasts in aging skin were meassured with technique of sterology.

背部被剪去3 cm×3 cm毛的12只20月龄豚鼠被随机均分为给药组和对照组，给药组涂抹红鹿制剂，对照组涂抹化妆品基质，连续涂抹60 d；应用天狼猩红、HE染色和体视学技术分别观察和测定老化皮肤中Ⅲ型胶原的分布、表皮基底层细胞的分裂指数、角质层同表皮厚度的比例、真皮胶原纤维和微血管的体密度和成纤维细胞的数目。

The testing, answering system was developed out by the ASP.net. Two test papers were abstracted from the system by the combination of the certain proportion and binominal distribution mathematical models stragety. The two test papers were tested by 52 students through the cross design. The difficulty and discrimination of items and the reliability and validity of the test papers were worked out with Education Statistics, factor analysis, relative analysis etc.

运用ASP.net技术开发了组卷、答卷、阅卷系统，应用重点等级定额比例分配与难度等级二项分布数学模型相结合的组卷策略随机抽出2套试卷，采用交叉设计对52名预防医学本科学生进行测试，用教育测量学原理、因子分析、相关性分析等方法分析两套试卷试题的难度、区分度和试卷的信度、效度。

Cronbach a of them equals respectively 1.000, 0.714. Conclusions The system could form the test pater with the strategy of the combination of the certain proportion of the important degree and the binominal distribution models which realized the Internet testing, rectifying and analysis.The test papers abstracted from the system were reliable and valid. It can scientificly, objectively evaluate the students' ability and it's beneficial to deviation of the teaching, testing and controlling testing cheat. The Non-paper testing system has good practical value.
