吸液

The plug is used along with downhole eccentric water distribution device. When the pressure of produced fluid and the water-absorption ability of the reservoir change, the plug regulates automatically the size of the fluid outlet by means of the action of the slide valve and balance spring, thereby a stable flow rate can be obtained.

这种堵塞器与井下偏心配水器配套使用，当注水的来液压力或地层的吸水能力改变时，通过堵塞器内滑阀和弹簧的作用，自动调节出液口的大小，使水嘴前后压差基本保持不变，起到保持流量稳定的作用。

Experimental group: Combined fluidity or whole nutrition liquid in transfusion bottle with blood transfusion tube were dripping into nose continually (GCS 4~8), control group was used by tradition nose feeding methods (nutrition fluid as experimental group), compared the gastrointestinal complication in the two groups (vomit and countercurrent, misabsorb, bluge, diarrhea, digestive tract bleed, astriction).

试验组用输液瓶装人混合流质或用能全力营养素配液接输血管持续滴注鼻饲法（CCS4~8分），对照组用传统方法鼻饲，比较两组鼻饲后胃肠道并发症（呕吐和返流、误吸、腹胀、腹泻、消化道出血、便秘）发生率。

Guangdong college of pharmacy,guangzhou,guangdong 510006,china;henan university of traditional chinese medicine,zhengzhou,henan 450008,chinaabstract:objective to establish a method for the determination of the content of total alkaloid in nao mai tong recipe.methods acid dye colorimetry was used in the determination with bromocresol green buffer solution as the color developing agent with absorbance was determined at the detection wavelength of 417 nm.results the calibration curve of the absorbance was linear with the concentration of ligustrazine in the range of 0.031～0.153 mg/ml(r=0.9998).the average recovery of ligustrazine was 100.95％,rsd=1.75%.

作者单位：广东药学院中药化学与分析教研室，广东广州 510006；河南中医学院，河南郑州 450008 目的建立脑脉通有效部位中总生物碱的含量测定方法。方法采用酸性染料比色法，以溴甲酚绿缓冲液作为生物碱的显色剂，测定样品溶液在417 nm波长处的吸收度。结果对照品川芎嗪质量浓度在0.031～0.153 mg/ml的范围内与吸光度呈良好的线性关系，r=0.9998。平均回收率为100.95％，rsd为1.75％。精密度和稳定性良好。

The main function of sucrose is to maintain normal respiration, so it can only be used to join the preservative, and make a good effect in maintaining the water balance of Dianthus Caryophyllus when dealing with 0.01% Phytic Acid +2% S +200 mg/L8-HQC solution; Finally, in the mensuration of Dianthus Caryophyllus fresh weight change, no matter using which the vase planting solution, the fresh weight of Dianthus Caryophyllus increases in the initial phase and then gradually decreases.

结果表明：在花径变化的测定中，经0.01%植酸+2%S+200mg/L8-HQC溶液处理的香石竹在保鲜期间得到最好的保鲜效果，切花的生长状况达到最佳状态；在水分平衡的测定中，结果表明蔗糖溶液对香石竹的水分平衡的保持有负作用，蔗糖的作用主要作用是维持正常的呼吸作用，因此它只能用来加入到保鲜剂中，处理0.01%植酸+2%S+200mg/L8-HQC在保持切花的水分平衡上起到较好的效果；最后在香石竹的鲜重变化测定中，无论什么瓶插液，香石竹切花的鲜重在初期阶段增加，然后逐渐减少，水分的吸收与丧失会有波动，但总趋势是失水量大于吸水量。

The result of experiment on different chemical control shows the best chemicals for cootrol Eriosoma lanigerum in the part trees above ground is 40%omethoate adding 1‰ washing powder (the ratio is 1:800). Applying 0.25 kg fortified benzene to the root of each tree can kill Eriosoma lanigerum in the root. In the past three years, chemical control as first, complementary with the measures of integrated control and quarantine techniques, the percentage of suffered trees in Malus pumila garden of 40.8 hm2 in Yimen County has decreased from 48.5%to 2.65%.

不同药剂的防治试验结果表明：40％的氧化乐果1：800倍液加1％o的洗衣粉是防治苹果地上部分棉蚜的较佳药液；另每株根施0.25kg高丙体内吸粉剂对根部的苹果棉蚜具有较好的杀灭作用。3年来，以化学防治为主，辅以配套的综合防治及检疫技术措施，使易门40.8hm2苹果园的植株受害率由48.5％降至2.65％，取得了较好防治效果。
