The results show t hat yttrium exists as the form of compound (Al2Y) in AZ31 magnesium alloy, and dystectic Al2Y as the heteromorphic nucleation emerges firstly in the cou rse of alloy precipitation, which refines the alloy's microstructure and obviou sly improves the mechanical properties at room and high temperature. The average grain size of AZ31 magnesium alloy containing Y is reduced by 35.82%. Tensile s trength, yield strength and elongation percentage reach 212 MPa, 147 MPa, and 7. 5% at room temperature respectively, and 117 MPa, 98 MPa, and 10.2% at 200 ℃ re spectively.

结果表明，Y在AZ31 镁合金中主要以块状Al2Y化合物形式存在；高熔点的Al2Y在合金凝固过程中首先析出，成为凝固的异质形核剂，从而细化了合金组织，改善了室温和高温力学性能；由于Y的强化，含Y AZ31镁合金平均晶粒尺寸降低幅度约为35.82 %；室温抗拉强度、屈服强度和延伸率分别为 212 MPa， 147 MPa和7.5%，200 ℃时分别为117 MPa， 98 MPa和10.2%。

在0-14GPa的压力下，含3.2wt%水的镁橄榄石比不含水镁橄榄石的Vp和vs值分别降低了3.1-7.1%和

Based on the detail geochemical research especially REE geochemistry, it is suggested that the Maowu ultramafite should be disaggregated into the complex rocks, which are composed of peridotite, garnet bearing harzburgite, eclogite and omphacitite.

毛屋岩体不是由多幕式镁铁超镁铁质层状堆晶作用形成的一套岩石系列，而是由橄榄岩类、含石榴石方辉岩类、榴辉岩类和绿辉石岩类组成的一个混杂岩体。

10 kt/a anti-block industrial potassium nitrate is using magnesium nitrate and potassium chloride as raw materials,with the new production techniques of producing potassium nitrate with the newly-developed double decomposition circulating reaction method.By-product magnesium chloride hexahydrated with a small amount of potassium nitrate is called nitrogen-potassium-magnesium fertilizer.

张罡摘要： 1万t防结块工业硝酸钾的生产装置选用硝酸镁与氯化钾为原料，采用新研究开发的复分解循环反应法生产硝酸钾新工艺，副产品为六水氯化镁，六水氯化镁含少量硝酸钾，故称之为氮钾镁肥。

阐述了镁质无光釉配料的改进方案，用含5%～30%MgO的熔块与镁质原料和其他釉原料配料，制备无光釉可获得饰面状态良好、无针孔缺陷的无光釉面。

For example, significant correlation in Zunyi prefecture was found between smoking total scores and total nitrogen, nitrogen to nicotine ratio and nicotine, and between offensive odor and total nitrogen and chloride.

在省级尺度，烟叶化学成分与烟叶品质的关系更为复杂，需用更多的化学成分（碳水化合物、含氮化合物及矿质养分）才能综合反映烟叶的品质，如吸食总分与总氮、糖碱比、氮碱比、磷、镁显著相关，杂气与总氮、糖碱比、氮碱比、磷、镁和还原糖显著相关。

At the prefecture scale, the relationship became complicated between chemical components and leaf quality, and more chemical components were needed to represent leaf quality. For example, significant correlation in Zunyi prefecture was found between smoking total scores with total nitrogen, nitrogen to nicotine ratio and nicotine, and between offensive odor with total nitrogen and chloride.

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
