The experimental results are shown that the microstructure of QT600-3 by CO_2 laser quenching is Aphanitic Martensite+Graphite,and residual stresses are all compressive,which is above 120 MPa,they increase with laser power.

结果表明：经CO_2激光淬火后QT600-3的显微组织为隐晶马氏体+石墨，残余应力均为压应力，其值在120 MPa以上，且随着功率的增大而增加；相变层深度随着扫描速率和光斑直径的增加而减小，且随着功率的增大而增加；激光淬火后的材料组织结构比较均匀，有利于提高凸轮轴的使用寿命。

Auriferous quartz veins of Dongping gold deposit are dated by fluid inclusion Rb-Sr isochron methed at 103±4Ma.

用石英流体包裹体Rb-Sr等时线法测得东坪金矿床含金石英脉的年龄为103±4Ma，比该矿的蚀变岩型矿体晚50-70Ma。

The aberrant phenotypes were observed in the anther of tobaccotransformed with ZM401 sense construct: the inflorescence growth and floral axiselongation are suppressed; the flower buds falling or flowers abscission earlier wereobserved. The degradation of tapetum are not observed at the binucleate pollen stagewhich corresponds to the mature stage, although the tapetal cells of untransformedtobacco anther at the same stage have already degenerated completely anddisappeared.

对转基因烟草进行形态学、组织学分析结果表明，ZM401基因以反向方式整合的转基因烟草表现一切正常，而含有ZM401正义基因的转基因烟草在表型和组织学上都出现了异常：花序生长缓慢，花序轴变短，生长过程中花逐渐脱落，花序轴褐化枯死；花药绒毡层退化延迟，药室内壁在雄配子体发育后期不能进行带状加厚，阻碍了花粉粒的释放。

The key advantages of the Suzuki cross-coupling are the mild reaction conditions and the commercial availability of the diverse boronic acids that are environmentally safer than the other organometallic reagents.

催化剂是suzuki偶联反应当中一个重要的因素，选择合适的催化剂不仅能够使反应条件变得比较温和而且能够提高反应产率，甚至能使原本不能发生的反应变为可能。Suzuki偶联反应的催化剂通常由两部分组成：钯源和配体。

In recent years, according to the zoopery of the extract of different medicine position such as root, nut and bark, the aqueous extract of leaf, nut and bark of Canarium Pimela Koening can decrease blood pressure rapidly and effectivly, The Liquid Extracts of Leave of Canarium Pimela Koening also have a quick effect of the negative inotropic action on heart.

近年来对乌榄叶、果和树皮不同药物部位提取物的动物实验表明：乌榄叶、果和树皮水提物均有快速显著的降压作用，乌榄叶水提物对离体蛙心还有快速显著的负性变力作用。

In recent years, according to the zoopery of the extract of different medicine position such as root, nut and bark, the aqueous extract of leaf, nut and bark of canarium pimela koening can decrease blood pressure rapidly and effectivly, the liquid extracts of leave of canarium pimela koening also have a quick effect of the negative inotropic action on heart.moreover fructus canarii pimelae can also resist oxidation and help fight against senium,guangdong has abundant resource of canarium pimela koening, but its medicinal efficacy has not been widely applied, which makes canarium pimela koening has important meaning and function of exploitation.

近年来对乌榄叶、果和树皮不同药物部位提取物的动物实验表明：乌榄叶、果和树皮水提物均有快速显著的降压作用，乌榄叶水提物对离体蛙心还有快速显著的负性变力作用。乌榄果还具有抗氧化、抗衰老作用。乌榄在广东资源丰富，但其药用功效并没有得到广泛应用，具有重要的开发作用与意义。

The microstructure evolution, precipitation behavior of carbonitride as microalloying element and its effects on deformation induced ferrite transformation of mild steels with various Nb, V content were investigated on a Gleeble 1500 thermechanical simulator through multi-pass thermo-compression in the temperature range of 820~790℃ to simulate the finish rolling process of plates.

在Gleeble 1500热模拟机上，通过820~790℃温度范围内的多道次热压缩变形模拟了中厚板的精轧工艺，考察了不同铌、钒含量的低碳钢的组织演变过程、微合金元素的碳氮化物的析出行为和对形变诱导铁素体相变的影响。
