X-ray diffraction Rietveld refinement results indicate that La2Ni1- y Co y O4+δ compositions have an orthorhombic structure with Fmmm space group. The substitution of partial La3+ with Co at the B-site caused an increase in the length of Ni/Co—O1 bond in the ab plane and La/Sr—O2 bond along c axis.

研究结果表明， La2Ni1- y Co y O4+δ具有正交结构， Co离子取代增加了钙钛矿层中 ab 平面上Ni/Co—O键的键长、岩盐层中沿 c 轴方向上La—O键的键长和非化学计量氧含量，并有利于改善材料的烧结性能。

After seedling trees of Yunhe Snow Pear were polluted by Pb(superscript 2+), Cd(superscript 2+), synthesis of chlorophyll was restrained, toxic effect of Pb(superscript 2+), Cd(superscript 2+) on seedling trees was intensified, membrane lipid peroxidation damage was increased. And the protective enzymes system start-up of polluted seedling trees enhanced antioxidative enzymes activities of seedling trees.

结论］Pb(上标 2+)、Cd(上标 2+)污染云和雪梨苗，抑制叶绿素的合成，增强超养阴离子自由基O2(上标-对植株的毒害性，使膜脂过氧化损伤程度高，受重金属污染植株启动保护酶系统，以增强植株的抗氧化性。

Density functional calculations predicted that both the ZrO3 and HfO3 molecules possess a closed-shell singlet ground state with a non-planar Cs geometry, in which the side-on coordinated O2 falls into the peroxide category.

结果表明ZrO3和HfO3都具有单重电子基态以及非平面的Cs构型，可以看作金属一氧化物二价正离子与过氧配体形成的络合物。

Smaller than the width of the pinhole is usually 10% of the small, small pinhole is characterized by the same-sized machine by using smaller needle sewing can be (able to guarantee shuttle hook back the role of the Central Line).

Z- Y3 f6 w， M& Z Y **的顶部至孔底端称为**的长度（O2），针身的长度增加时，**的长度亦随之而增加，**的宽度一般为针身直径的40 %。低于40 %，称为&小**&；高于40 %，称为&宽**。
