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。

Arundinacea in vitro. After cultivation on PDA at 26℃ under continuous fluorescent light for 6 days, the colonies were black green and the hyphae were septate. Spore size was 30.6~17.0 μm×10.9~13.6 μm, mostly with four-septa. The central cell was dark and the third cell from the base was the largest. The DNA sequence of ribosomal ITS of the isolates was found to match 100% with an ITS sequence of Curvularia affinis in GenBank. This is the first report of leaf spot caused by C. affinis on F.

结果表明:该病原菌能侵染高羊茅,在26℃和光照下,在PDA培养基上培养6d后菌落呈墨绿色,菌丝有隔,分生孢子有4个横隔膜,平均大小为30.6~17.0μm×10.9~13.6μm,中部3胞暗色,第3个细胞基部膨大;其核糖体DNA-ITS序列分析表明,该菌与GenBank中近缘弯孢的同源性是100%;结合形态学特征和致病性测定,认为该菌为C。

结果 采用40个随机引物共检测72个位点,其中多态位点27个,占37.5%;相似系数矩阵表明野生越桔和栽培越桔Ⅰ、栽培越桔Ⅱ的遗传距离分别为0.764和0.809;聚类图表明野生越桔和栽培越桔Ⅱ亲缘关系较近。

The conditions to produce PP-g-PVOH with the highest SP 60% were: ethyl alcohol/butyl alcohol=30/70, NaOH%=0.5%, refluxing at 90℃ for 16hr.FTIR confirmed graft and saponification reactions, and it was identified that graft reaction influence porosity and morphology very little, but microparticles in PP granule were sightly swelled. There was a peak relationship between melt flowing index and GP and the flowing property was decreased with sponification reactions.

红外光谱证实了接枝和醇解反应的发生;孔隙率和PP粒子内部形貌观察的结果表明,接枝反应对粒子孔隙率的影响不大,但其内部微粒有所溶胀;接枝率增大,熔融指数呈现先上升后下降的趋势,对材料力学性能的研究表明,随PP-g-PVAc接枝率的增加,材料的断裂伸长率和拉伸强度先增加后降低,拉伸模量逐渐增加,材料的缺口冲击强度降低。

Changes of silver carp muscle protein s during chilled storage;2. The changes of rheology,texture and color of minced pork after the cooking respectively in water bath,retort and microwave were tested,based on which the effects of muscle protein and transglutaminase contents on the gel properties of minced pork were then investigated.

结果表明:3种热处理方法下,一定量的转谷氨酰胺酶及肌肉蛋白使猪肉糜表现出不同的颜色和质构特性;与其他两种方法相比,水浴加热使猪肉糜更具有弹性;加入MTGase后,样品的储能模量G′增大,表明MTGase的加入影响了猪肉糜的流变特性、颜色以及质构,其效力取决于猪肉糜的热处理方法。
