The calibration curve of the SM2-Kit with standard SM2 inhibitor was typical sigmoid curve fitted to the four parameter logistic equation with the linear detection of 0.625 μg/L to 80.0 μg/L (R2=0.9911), the sensitivity of 0.9 μg/L, the IC50 of 5.82 μg/L and the detection limit of 1 μg/L. The recoveries of SM2 spiked in pig feed were 83.4 %, in pig urine were 89.5 %. The precision and accuracy of the assay as determined by inter-assay and intra-assay coefficient variation was both below 15 %. The SM2-Kit generally had 2.08 % cross-reactivity towards sulfamerazine and little or no cross-reactivity towards other sulfonamides. The dilution solution of SM2 had no effect on results of SM2-Kit. The validity of SM2-Kit in 4 ℃ was above six months.

The wavelet variance verification also indicates that the first main period of the runoff of mountainous watershed in the Shiyang River Basin is 30years, and 22years and l5years are the second and third period respectively; 3 Then we also compared the total runoff of mountain watershed with climate factors of Wushaoling which station is in the mountain headstream area, such as precipitation and temperature, the data record that the correlation coefficient of annual runoff and precipitation variation over the upper reaches in the Shiyang River Basin is 0.61 ,which indicates precipitation is the main water recharge of the runoff.

石羊河流域出山口年径流的周期变化与乌鞘岭站年降水量和年均气温周期基本上都能在同一周期上下浮动,其中出山口年径流量与乌鞘岭山区年降水量相关系数为0.61,说明地表径流量主要是由山区降水补给;年径流量与山区年均气温变化呈0.28的反相关,说明该流域近50年来出山口径流与山区气温呈反比,即径流量随年均气温上升而减少,相关性暂时不十分明显。
