The concentrating energy source focuses the energy down and reduces percussion for the ground by using the theory of directional charge
聚能震源弹采用定向聚能的原理，使激发的能量集中向下，减少了对地面的冲击。
The composites not only show excellent photo - responsive properties in the visible and near - ir region ( 450 ~ 850 nm ) , but also show complementary and synergetic enhancement effects in photosensitivity in the visible and near - ir region . the reasons for the enhanced photoconductive properties and new effects are explained in terms of the partial and directional charge transfer from phthalocyanine to azo compound in these azo / tiopc composites . 2
研究发现这两种复合材料体系在可见光区和近红外光区( 450 850nm )均有光谱响应，光谱响应范围得到了拓宽，并在该波长范围内都有优良的光电导性能，呈现出明显的光电导性能协同增强和互补效应，该复合材料体系中酞菁向偶氮发生的部分定向的电荷转移是光电导性能协同增强和互补效应产生的物理起因。
