The proteins in milk and dairy products were mostly eliminated by the precipitators. Three aseptics and two sweeteners were separated on a C18 column with the mobile phase of methanol -0.05mol/L potassium dihydrogen phosphate under gradient elution. With a diode array detector, acesulfame, benzoic acid, and sorbic acid were detected at 230 nm and sodium saccharin and aspartame were detected at 210nm.

通过加入适量沉淀剂除去样品中绝大部分蛋白质后，采用C18色谱柱分离，以甲醇－0.05mol/L磷酸二氢钾溶液为流动相梯度洗脱，用二极管阵列检测器于230nm波长处检测安赛蜜、苯甲酸和山梨酸，于210nm波长处检测糖精钠和阿斯巴甜。

Methods:A runn ing buffer consisted of 30 mmol/L NaH2PO4(pH2.7),a voltage of 20 kV and a UV detector at 230 nm were adopted in this methos.

以30mmol/L磷酸二氢钠（pH2.7）缓冲液为运行缓冲液，运行电压为20kV，检测波长为230nm。

With the single factor test and orthogonal test, the optimal culture media for HF3-04 strain producing agarase was decided as: agar 3‰, NH4NO31‰, Na2HPO4 0.5 mM, pH 8.0. The optimal fermentation conditions were inoculum size 3‰, 110ml medium in 250mL Erlenmeyer flask, rotation rate 150r∕min, culture time 48h,culture temperature 25℃.

通过正交试验确定其最佳培养基组成为琼胶3‰、硝酸铵1‰、磷酸氢二钠0.5mM、pH值8.0；该菌株的最佳培养条件为接种量1%、装液量为250ml三角瓶装入110ml发酵培养基、摇床转速150r∕min、培养温度25℃、培养时间48h。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
