The results show that the major contribution to DOS of Mg and Pb are the 2p orbit of Mg and the 5d orbit of Pb, followed by the 3s orbit of Mg and the 6p orbit of Pb, the 6s orbit of Pb is the smallest one. There are a large number of charges around Mg, it has the characteristics of typical metal bond. Mg and Pb share some charges to form covalent bond, but the distortion of the charge at the junction is little; the proportion of covalent bond is less than the metal bond, Mg2Pb is semimetal. The elastic modulus and shear modulus of Mg2Pb are 68.6 and 27.9 GPa, respectively. Based on Pugh empirical criterions and Poisson's ratio, Mg2Pb is brittle in nature.
结果表明:Mg和Pb对态密度的贡献主要是Mg的2p轨道和Pb的5d轨道,其次为Mg的3s轨道和Pb的6p轨道,Pb的6s轨道贡献最小;在Mg原子周围有大量的电荷存在,呈典型的金属键特征,Mg、Pb之间存在共用的电荷,有较强的离域性,以共价键形式存在,但交界电荷的畸变不大,故共价键所占比例较少,金属键所占比例较大,Mg2Pb化合物呈半金属性;Mg2Pb的弹性模量和切变模量分别为68.6和27.9 GPa,Pugh经验判据和泊松比均表明Mg2Pb具有脆性。

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。

There, on the soft sand, a few feet away from our elders, we would sprawl all morning, in a petrified paroxysm of desire, and take advantage of every blessed quirk in space and time to touch each other: her hand, half-hidden in the sand, would creep toward me, its slender brown fingers sleepwalking nearer and nearer; then, her opalescent knee would start on a long cautious journey; sometimes a chance rampart built by younger children granted us sufficient concealment to graze each other's salty lips; these incomplete contacts drove our healthy and inexperienced young bodies to such a state of exasperation that not even the cold blue water, under which we still clawed at each other, could bring relief.
在软和的沙滩上,我们整个早晨都平躺在离大人仅有几英尺的地方,尽力压抑涌动的欲望,抓住每一次珍贵的时间和空间的机会来接触对方:她半埋在沙中的手,会慢慢的向我掘进,那棕色的瘦小的手指像梦游一样渐渐的走近;接下来,她乳白色的膝盖会开始一个小心翼翼的漫长的旅行;有时候,一些嬉戏的小孩修筑的沙堡会赐给我们足够掩护以遮住我们交接的咸腥的嘴唇……这些不完整的接触将我们健康且缺乏经验的幼嫩身体带入了邻近爆发的境地,就连掩盖着我们抓紧的双手的寒冷的蓝色海水也无法将其平息。

Film, sulphuric acid paper haihong-type: this type of original, exposure time, should be carefully handle, because some of the pictures and texts used in film than sulfate for paper document the required exposure time to increase twice as much, or even better, this type of original in exposed not only to ready a sheet of typing paper to retaining to part of the exposure time, but also to prepare a ratio of sulphuric acid paper size large waste PS version mastering sulfuric acid paper blocked the view of typing paper, and the film also exposure, this piece of PS version is good to all of retaining this side of sulfuric acid paper for extending the original copy for the last half of the original version, so that the exposure time of light and dark sides.
