Precautions against over exposure to the sun are given in the new pamphlet be safe in the sun - beware of uv radiation produced jointly by hko and dh to raise the public awareness on the issue 这小册子也慨述了紫外线辐射的来源和种类、紫外线辐射对人体的影响及紫外线指数分级法的基本资料，以提高市民在这方面的认识。
A water soluble crude polysaccharide in the cells has been isolated from the zymogen thread of hericium erinaceus pers . after the crude polysaccharide has been deamylumized by the combined methods of enzyme and sevage , the four graded component - hpa , hpb , hpc , hpd - would be abstracted by the method of ethanol grading 从猴头菌( hericiumerinaceuspers )发酵菌丝体中提取出胞内水溶性粗多糖，经酶法和sevage法联合脱蛋白后，用乙醇分级法分离出hpa 、 hpb 、 hpc 、 hpd四种级分。
Fourth , according to the weibull distributing functions of equivalent loads , calculated the max loads by expanded sample method , acquired eight routine loads spectrum of each roads taking advantages of the connover classification method , calculated the respective enhancement coefficient in principle of amended miner linear accumulated fatigue damage rule , by the comparative norm of general tar - paved road , educed the mathematical model of calculating enhancement coefficient of synthesized roads 利用数理统计的方法得到了各路面的等效载荷的weibull分布函数。第四，根据各路面的等效载荷的weibull分布函数采用扩展样本法求得了各路面的极值载荷，按照connover的分级法得到了各路面的八级程序载荷谱。以一般沥青公路为比较基准，采用修正的miner线性累积损伤理论，根据前桥的s - n和p - s - n关系式得到了各路面的强化系数，建立了综合路面的强化系数计算的数学模型。
