在每个灯光属性下,我将细分(subdivs)设置为10000,焦散系数(caustic multiplier)设置为2.5,因为1.0的系数下反射焦散和光照功率之间的均衡和2.5是有很大的差距的。
Under each light properties I had 10,000 subdivs with 2.5x caustic multiplier just because the balance between the rendered caustic and light power felt way off with only 1.0x in the multiplier.
传统测量电感的自感系数是用交流电桥,它存在平衡点较难找,并且在空间杂散信号干扰下很容易产生误差。
The measuring of self-inductance coefficient by means of direct current bridge method has reduced the difficult and improved the precision of measuring.
