Methane, oxygen and H_2O molecules are activated, ionized and dissociated into active particles such as CH_3~+, O~-, H_2O~+, CH_3, CH_2, CH, H,OH and O, by nonelastic collision with high energy electrons. The particles react with each other in the reactor to synthesize chemically products including gaseous oxy-hydrocarbons.We study the rule of reaction by changing electrical parameter, gas flow etc. Study the conversion of methane, selectivity of gaseous hydrocarbons and yield of methanol under different reaction condition.

针对常规甲烷催化转化和氧化偶联制备含氧化合物的问题，遵循国际化学科学研究前沿"绿色化学"原则，采用自然界存在丰富的CH_4、H_2O和O_2为原料，在绿色友好的常温大气压无任何催化剂的条件下，采用强电场电离放电加速电子及其激励气体分子的极端物理手段，在反应腔体内进行无任何环境污染的非平衡等离子体化学反应，将气体分子激发、电离、离解成CH_4~+、CH_3~+、CH_4~·、H_2O~+、H_2O~·、O_2~+、O(~1D)等活性粒子，生成气态烃及含氧碳氢化合物，整个反应过程实现零污染、零副产品。

As part of the Stroke Prevention in Young Women study, which is evaluating genetic and nongenetic ischemic stroke risk factors in young women, the investigators systematically searched the PDE4D gene for novel and known polymorphisms in 48 African-American women and 48 white women. These polymorphisms were then prioritized and genotyped in the entire study population of 224 cases of first ischemic stroke and 211 age- and race-matched controls.

年轻妇女中风预防研究里面的一部分，评估年轻妇女基因性和非基因性缺血性中风风险因子，研究者系统式蒐寻48位非裔美籍妇女和 48位白种妇女之PDE4D基因之新的和已知的多型体，这些多型体按基因型顺序排好，400位之中有224例首次缺血性中风，有211位是年纪和种族配对控制组。

Finally, we present an arithmetic of multiplehypocentral, heterogenous dislocation, and a multirupture segment superposition model for simulating the earthquake deformation field. The simulated LOS interferometry map presents the distribution characteristics of the earthquake deformation field better than that of previous studied. Meanwhile, a suit of fault geometric parameters of the earthquake is also obtained by the study. Having a better effect upon simulating asymmetry, great dislocation, macro rupture field, and nonhomogeneity of dislocation than the traditional model, the multisegment method is a progress of this work. It provides a better explanation for the study on hypocentral parameters.

基于上述原因，本文对Okada线弹性位错模型的算法进行了改进，提出了"多震源、非均一位错分量、多破裂段叠加"的线弹性模型，该模型模拟出的形变场干涉纹图较好地体现了地震形变场的分布特征，并由此获得了一套较为完整的地震发震断层的几何学特征参数，为破裂带长度、破裂面方向、破裂面大小等震源破裂特征参数研究提供了较好的解释。

The study included all neonates who were 34 weeks obstetrical estimated gestational age or less born between January 1, 2003 and November 30, 2007 at the Parkland Memorial Hospital in Dallas. Researchers excluded infants who were nonviable, transferred from other nurseries, or had missed critical data points. Of the 2183 newborns included in the study, more than half were hypothermic, defined as a rectal temperature of less than 36.5 °C. Euthermia was defined as a rectal temperature of 36.5 °C to 37.5 °C.
