指标化结果表明：红色相钼铬酸铅固溶体属单斜晶系，空间群C_2/c，a；7.250(8A，b：12.444(7)A，c：5.119(5)人，夕=132.58(6)°，化学式PbCr_(0.88Mo_(0.12)O_4每个单胞由四个分子组成所得粉末衍射的数据可以代替JCPDS19—685号卡片，可以用定量PbCrO_4相含量的方法来表征颜料的质量。

Under cyclic pressure or torsion load, Four factors with two levels that might influence component stability were assembled into eight performing conditions by orthogonal design. Axial compression micromotion and torsion micromotion were cellected under the eight working conditions.

根据临床上多见的可能对假体微动产生影响的四种因素分设两个水平，采用正交设计方案，组合成8种处理工况对三翼臼进行轴向循环压力载荷测试，同理进行三翼臼的循环扭矩载荷测试。

Kinesin is plentiful in various kinds of cells, different stages of cell development and multicellular organisms.

The results showed that the four treatments of cytochrome c supplemented with ATP all suppressed the pollen germination and pollen tube growth, and induced nuclear DNA degradation, different treatments with different ratios of double nuclei, single nucleus, and no nuclei. Treatment with heavy concentration of ATP also restrained pollen germination and pollen tube growth, but can not induced nuclear DNA degration.

结果表明，细胞色素c和ATP混合处理的四个组合都能抑制离体花粉萌发和花粉管生长，并且引起了花粉管核DNA的降解，不同处理中双核、单核及无核花粉管所占比率存在明显差异；高浓度ATP虽能抑制花粉萌发和花粉管生长，但不能引起花粉管核DNA的降解。

Effect of solute adsorption on vapor pressure osmometry measurment was studied by four low molecular weight organic compounds and five narrow MWD oliomeric polystyrene samples with known average molecular weight in Knauer VPO apparatus.

在气相渗透仪上，用四个低分子量有机化合物和五个已知平均分子量的窄分布聚苯乙烯低聚体，对VPO方法中的溶质吸附效应作了研究，提出了一种对吸附效应作改正的方法。

Our aim was to do a combined analysis of three randomised clinical trials to assess the effect of a prophylactic quadrivalent HPV vaccine on the incidence of these diseases.

我们的目标是通过三组随机临床试验的联合分析来评估预防性四价体HPV疫苗在这些疾病发病率中的作用。
