查询词典 superimposition

The protocol is summarized in Figure 18.16. A radioactive probe representing a gene (most often a labeled cDNA clone derived from the mRNA) is hybridized withthe denatured DNA of the polytene chromosomes in situ. Autoradiography identifies the position or positions of the corresponding genes by the superimposition of grains at a particular band or bands.

如图26.15所示为此过程草图：一个放射性探针代表一个基因（常是一个从mRNA中克隆得到的cDNA），它与原位多线染色体的变性DNA杂交，放射自显影仪可通过叠印特定纹带的纹理来识别应答基因的位置。

转向盘角阶跃输入的仿真分析表明，该方法可获得优于4WS和主动悬架简单叠加时的综合性能。

The result showed that the strong storm followed by mesoscale squall line was primary cause of strong sandstorm producing, steps and ladders short wave trough of 500 hPa was great criterion triggering system for the mesoscale squall line producing, the essential dynamic condition was provided by distortion field and the mesoscale low pressure of 700 hPa for the strong sandstorm forming and maintaining in mid-west of Hexi Corridor, the deep vertical circulation development condition was basic power that urged squall line to occur and sand dust to curl up, which was provided for the deep convection development by superimposition of lifting movement before ground cold front and ascendant current of secondary circulation in upper air jet entrance region, temperature and the barometric gradient around the cold front was enlarged by enhancement of ground thermal low and temperature diurnalvariation of afternoon, by which essential thermal energy unstable condition was provided for the gale and strong sandstorm eruption, the strong sandstorm appeared in downstream of -200 m^2s^(-2) center of vertical helicity, the vertical helicity had good instruction significance for development of squall line and landing region of sandstorm, the mesoscale squall line occurred in unstable stratification, basic condition of potential energy transforming as kinetic energy was provided by strong unstable stratification for the strong sandstorm forming and developing.

结果表明：中尺度飑线所伴随的强风暴是产生强沙尘暴的主要原因；500 hPa阶梯短波槽是中尺度飑线产生的大尺度触发系统，河西走廊中西部700 hp变形场、中尺度低压为强沙尘暴形成和维持提供了必要的动力条件；地面冷锋前上升运动与高空急流入口区次级环流的上升气流的叠加，为深对流发展提供了深厚的垂直环流发展条件，是促使飑线发生和沙尘卷起的基本动力；地面热低压的加强和午后气温的日变化加大了冷锋前后的温度和气压梯度，为大风、强沙尘暴爆发提供了必要的热力不稳定条件；强沙尘暴出现在垂直螺旋度为－200平方公尺/s^2中心的下游，垂直螺旋度对飑线的发展和沙尘暴的落区具有较好的指示意义；中尺度飑线发生在不稳定层结内，较强的不稳定层结为强沙尘暴形成、发展提供了位能转化为动能的基本条件。

Analyses of the relationship among strength factor, structure and reservoir permeability show that the high permeability zones of the No.3 coal seam in the Shanxi Formation of CBM development blocks in the southern Qinshui Basin commonly occur in the fold axial region with a low strength factor and relatively strong deformation of rock mass, especially the superimposition region of multistage fold axes, where strong deformation resulting in welldeveloped fractures in coal seams.

通过分析强度因子、构造和储层渗透性的关系发现，沁南煤层气开发区块山西组3号煤的高渗区往往位于岩体强度因子较低的、岩体变形较强烈的褶皱轴部，特别是多期褶皱轴部叠加部位，强烈的变形使得这些部位的煤体裂隙较为发育。
