In the experiment section, there"re three experiments investigating implicit attitude and dual-attitude model. In the first experiment, the author studies the effects of attitude strengthen on attitude"s automatic activation effect. In the second experiment , the author studies the effect of delay condition on the attitude"s automatic activation effect. Delay condition make experiment approach to mere exposure of attitude object, and two experiment demonstrate attitude"s automatic activation effect is the result of noncognitive processing.
第一个实验,探讨了态度强度对态度自动激活效应范式的影响,结果发现态度强度不是影响态度自动激活效应的因素;在第二个实验中,探讨了时距对态度自动激活效应的影响,时距控制使得实验更接近于态度物的单纯呈现,结果发现时距没有对自动态度激活效应产生影响,从而论证自动态度激活效应可能是非认知系统作用的结果,具有普遍性。

One is Bardina vorticity modification, and the other is Richardson number modification. Prediction results show that Bardina method has a superior capacity to Richardson number modification. Since DSM model has improved predictive results of the reversed velocity and tangential velocity, it is a potential method to predict strong swirling nonisotropic turbulent flow in stead of the longer convergence time.
本文采用了基于旋转体系使湍流脉动加强和削弱两种作用的修正方法对k-ε双方程的湍流耗散率方程进行修正,计算结果表明,从旋转体系可使湍流能量加强出发的Bardina涡量修正方法,预报回流区范围缩小,更加接近于试验值,其计算结果优于使湍流脉动削弱的Richardson修正。

Based on relative literatures,this part has included five resesearch aspects as below.1 Fifteen compounds were isolated and purified by extraction,column chromatography,and their structures were determined on the basis of spectral analysis: acteoside(Ⅰ-1),isoacteoside(Ⅰ-2),crenatoside(Ⅰ-3),cistanoside F(Ⅰ-4),sinapoyl-4-O-β-D-glucoside(Ⅰ-5),adenosine(Ⅰ-6),β-siterol(Ⅰ-7),oleanic acid(Ⅰ-8), succinic acid(Ⅰ-9),caffeic acid(Ⅰ-10),protocatechuic aldehyde(Ⅰ-11),p-hydro xybenzyl alcohol(Ⅰ-12),β-daucosterol(Ⅰ-13),D-galacitol(Ⅰ-14),D-mannitol(Ⅰ-15).Ⅰ-4~15 were obtained from this plant for the first time,andⅠ-6,7,9,and 13 were isolated from Orobanche genus for the first time.2 The scavenging test of DPPH showed that most compounds have comparative antioxidant activity as L-ascorbic acid and part of them show better activity such as the O.coerulescens extract and phenylethanoid glycosides.Acteoside showed potent free radical scavenging effects with a median inhibition concentration of 25.6μg/ml.3 The anti-HBV activities of acteoside,isoacteoside and crenatoside were measured,and all of them showed suppressive activity on the expression of HBsAg and HBeAg in the HepG2.2.15 cell line.
本论文在文献调研基础上对紫花列当化学成分及生物活性进行了研究,并从免疫抗病毒角度探讨紫花列当中特征性成分类叶升麻苷的肝保护作用及其机制。1采用大孔树脂、硅胶和Sephadex LH-20等色谱技术对紫花列当进行系统的植物化学研究,从中分离得到19个化合物,利用UV和NMR等波谱手段及理化性质鉴定了其中的15个化合物,分别为类叶升麻苷(Ⅰ-1)、异类叶升麻苷(Ⅰ-2)、crenatoside(Ⅰ-3)、cistanoside F(Ⅰ-4)、sinapoyl-4-O-β-D-glucoside(Ⅰ-5)、腺苷(Ⅰ-6)、β-谷甾醇(Ⅰ-7)、齐墩果酸(Ⅰ-8)、琥珀酸(Ⅰ-9)、咖啡酸(Ⅰ-10)、原儿茶醛(Ⅰ-11)、对羟甲基苯甲酸(Ⅰ-12)、β-胡萝卜苷(Ⅰ-13)、D-半乳糖醇(Ⅰ-14)和甘露醇(Ⅰ-15除化合物Ⅰ-1、Ⅰ-2和Ⅰ-3外,其余化合物均为首次从该植物中分离得到。2)通过大孔树脂富集该药材有效部位苯乙醇总苷,并采用HPLC测得其所含特征性成分类叶升麻苷的含量可达80%以上。3DPPH自由基清除试验显示紫花列当提取物及其所含的苯乙醇苷类化合物均具有较好的抗氧化能力,其清除DPPH自由基能力接近于抗坏血酸。4采用卡介苗整体致敏、脂多糖离体攻击构建大鼠原代肝细胞免疫性损伤模型,在体外观察类叶升麻苷的保肝作用。

The cumulative distribution of the ABI measured by the two methods demonstrated that the differences among them were not homogeneously distributed across the range of ABI value. The Doppler and oscillometric ABI readings were similar below values of 0.9, at values between 0.9 and 1.16 ,the readings were nearly the same line, whereas at values exceeding 1.16, the readings were not parallel.
5多普勒法与示波法测量所得ABI值结果之差均数为0.009(95%CI -0.24~0.2),非常接近于0,在95%可信区间之外的人数为48例(4.8%),在误差允许范围之内,表明两者一致性较好,并且这一差值随着ABI值的增加数值逐渐减小(r=-0.09,p=0.002)。

MPH plastic magnetic pump complies with JB/T7742-1995Standard for Small Magnetic Transmission Centrifugal Pump. Its flow-through parts adopt PPS with corrosion resistance to most acid, alkali and salt (except oxidable acid like strong sul-furic acid, nitric acid and aqua regia). Its performance is close to the chemical performance of F4, which can resist to most organic solvents under 100℃, especially to the mixture of gas and carbinol. Thus it is an ideal pump for acid and alkali industries.
MPH型塑料磁力泵符合JB/T 7742-1995《小型磁力传动离心泵》标准,过流部件采用聚苯硫醚,不受大多数酸、碱、盐的侵蚀(除氧化性酸如浓硫酸、硝酸和王水等),其性能接近于聚四氟乙烯的化学性能,在100℃以下能耐大多数有机溶剂,特别能耐汽油和甲醇的混和液,是酸碱工业中的理想用泵。
