Using finite difference time domain method, the electromagnetic field distribution of THz wave is simulated in a THz 2D PC splitter and by plane wave expansion method the dispersion relation and defect modes are achieved in a THz rotated PC waveguide.5. A woodpile three-dimensional (3D) PC with face-centered-tetragonal symmetry is one of the most popular 3D PCs because of its favorable band gap characteristics. Based on the woodpile fct lattice structure, we propose a novel woodpile THz lattice structure with comparatively decreased symmetry, better band gap properties and easy fabrication by varying some structure parameters.

After disinfection and medical activities before, samples were taken from three points in a diagonal of a relatively closed space with area not more than 30 square meters. In general, one point was from diagonal center, and the other two points from the two ends with one meter distance to walls. When the area exceeded 30 square meters, samples were collected from five points, one was from the center, and the other four points from four angles with one meter distance to walls, and the altitude was 80-150 cm from vertical distance to the ground. The total number of microbes not more than 200cfu/m^3 was considered qualified.

消毒后和进行医疗活动之前，相对封闭的空间，面积≤30平方公尺时，在一条对角线上取3点采样，一般是中心和两端距墙壁1米处各取1点；面积＞30平方公尺时，应取中央及四角距墙壁1米处共5点采样，布放高度为垂直地面80cm~150cm，微生物总数≤200cfu/立方公尺为合格。

The results show that there is a linear correlation between magnetic susceptibility and density. Take 1.6 g/cm^3 as a boundary value, the magnetism of high density coal and low density coal was opposite. The diamagnetism property of low density coal weakens and the paramagnetism of high density coal enhances along with the size reduction of fine coal. The magnetic field intensity influences the magnetism of coal.

研究表明：比磁化率同密度间存在线性相关关系，以1.6 g/立方公分为界，高、低密度级煤分别呈顺磁性和逆磁性，且随煤粉粒度的减小，低密度级煤的逆磁性减弱，而高密度级煤的顺磁性增强；磁场强度对煤的磁性有一定影响。
