High levels of uncertainty in non-methane volatile organic compound （NMVOC） emissions in china could lead to significant variation in the budget of the sum of hydroxyl （OH） and peroxy （HO2.RO2. radicals （ROx =OH ＋ HO2.＋ RO2. and the ozone production rate [P（O3）],but few studies have investigated this possibility,particularly with three-dimensional air quality *** added diagnostic variables into the WRF-Chem model to assess the impact of the uncertainty in anthropogenic NMVOC （AVOC） emissions on the ROx budget and P（O3） in the beijing-Tianjin-Hebei region,Yangtze River Delta,and Pearl River Delta of *** WRF-Chem simulations were compared with satellite and ground observations,and previous observation-based model *** indicated that 68％ increases （decreases） in AVOC emissions produced 4％-2.0％ increases （2.-80％ decreases） in the concentrations of OH,HO2.and RO2.in the three regions,and resulted in 35％-48％ enhancements （2.％-39％ reductions） in the primary ROx production and ～ 65％ decreases （68％-73％ increases） of the P（O3） in beijing,Shanghai,and *** the three cities,the two largest contributors to the ROx production rate were the reaction of O1D ＋ H2. and photolysis of HCHO,ALD2.and others; the reaction of OH ＋ NO2.（71％-85％） was the major ROx sink; and the major contributor to P（O3） was the reaction of HO2.＋ NO （～ 65％）.Our results showed that AVOC emissions in 2.06 from Zhang et al.（2.09） have been underestimated by ～ 68％ in suburban areas and by ＞ 68％ in urban areas,implying that daily and hourly concentrations of secondary organic aerosols and inorganic aerosols could be substantially underestimated,and cloud condensation nuclei could be underestimated,whereas local and regional radiation was overestimated.

In this paper, Cr-doped LiSrAlF6 crystals are investigated using high-temperature Raman spectroscopy and the single-crystal Raman spectra of Cr：LiSrAlF6 are analysed by factor group theory and comparison with other fluorides. The results indicate that Cr：LiSrAlF6 is stable below its melting point; Raman peaks located at 561,32. and 2.0 cm-1 are assigned to the Alg modes of AlF6, SrF6 and LiF6 octachdra, respectively; with temperature increasing, Raman peaks associated with AlF6 octahedra shift towards low frequencies, while LiF6 and SrF6 octahedra are temperature- insensitive; around the crystal melting point, three new Raman peaks occur, which are associated with the AlF6 octahedral chain structure. Finally, the microstruetural evolution of Cr：LiSrAlF6 from room temperature to its melting point is discussed based on its Raman spectra.
