Convert the XYZ values to Lab using the following formulas. Note that we typically use the 2° standard observer for this conversion, as it is the most commonly used for color matching.\[X_n = 0.95047 \quad (\text{reference white point for D65 illuminant})\]\[Y_n = 1.00000\]\[Z_n = 1.08883\]\[f(t) = \begin{cases}t^{\frac{1}{3}} & \text{if } t 0.008856 \\7.787 \cdot t + \frac{16}{116} & \text{otherwise}\end{cases}\]\[L^* = 116 \cdot f\left(\frac{Y}{Y_n}\right) – 16\]\[a^* = 500 \cdot \left( f\left(\frac{X}{X_n}\right) – f\left(\frac{Y}{Y_n}\right) \right)\]\[b^* = 200 \cdot \left( f\left(\frac{Y}{Y_n}\right) – f\left(\frac{Z}{Z_n}\right) \right)\]
此外，海信还为年轻人推出“大薄荷2.0套系”，在电器“更大更薄更有核”基础上，增加了全屋AI智控：当用户推开房门，AI空气管家就能调到适合的温度；打开电视，AI已选好喜欢的电视节目、适宜的亮度；AI洗护管家面对材质混杂的衣服，自动识别洗净。
Highly Divergent Profiles: For routing configurations that are not pre-calculated as common scenarios and whose costs vary too much from default configurations, the original A* algorithm might still be faster (and is often used as an automatic fallback).。搜狗输入法对此有专业解读
