Pretreatment of arsenical refractory gold concentrate - Leaching by sodium dichromate ;2. The solution of sulfuric acid was added dropwise to the reaction vessel contained 1,3-dichloro-2-propanol, sodium dichromate and water.

将硫酸水溶液滴加到1，3-二氯-2-丙醇与重铬酸钠水溶液的混合物中，在温度23~27℃的条件下搅拌反应5 h，重铬酸钠∶1，3-二氯-2-丙醇=1∶2，此条件下收率为79。

Through research, we find that the non-uniform dispersion of butyraldehyde in PVA solution is the main reason of PVB agglomeration. Adding butyraldehyde to the PVA solution at the temperature of 40-60℃can ensure the uniform dispersion of butaraldehyde in PVA solution.

通过改变工艺条件，在40-60℃的条件下，将正丁醛加入PVA溶液中，可保证正丁醛分散均匀，降至适当温度后，再滴加盐酸，这样在不加任何乳化剂的条件下也得到了粉末状的PVB产品。

Cook whole chickens breast-side down using the indirect method, place a drip pan under the chicken and cook with the lid closed.

库克全鸡母乳下采用间接方法，放置一个下滴锅鸡，并与厨师一边盖封闭。

Drop volume method was used to measure the dynamic interfacial tension at the crude oil/brine interface.

用滴体积法测定了原油/盐水的动界面张力，在三种不同的温度下，当非离子原油破乳剂存在时，在不同的破乳剂浓度下，测定了各体系的动界面张力。

I looked mopishly at the sinuate black outline that you left behind, a tear dropped.

我惘然对着你遗留下的黑曲线的轮廓掉下一滴泪来。

Comparison of the virus concentrations was made by serological precipitin test and local lesion counts on half-leaves of Gomphrena globosa.

块茎在黑暗和光照下发芽的试验表示，在光照下发出的幼芽内X-病毒浓度显著低于黑暗下发芽的，其沉淀滴度的比例约为1∶4。

The solution of sulfuric acid was added dropwise to the reaction vessel contained 1,3-dichloro-2-propanol, sodium dichromate and water.

将硫酸水溶液滴加到1，3-二氯-2-丙醇与重铬酸钠水溶液的混合物中，在温度23~27℃的条件下搅拌反应5 h，重铬酸钠∶1，3-二氯-2-丙醇=1∶2，此条件下收率为79.6%。

In this study, sulfate radical concentration from 4 drip water points (PL1, PL2, SH, JG) in the Shihua cave have been monitored for three years, and those from the drip water point was monitored for two years. Drip discharges show three types of response to surface precipitation variations: rapid response, response with associated time-lag and stable. The results show that:(1) SO(superscript 2- subscript 4) concentration in rapid response drip water increases sharply during rain period and has a exponential relationship with drip rate;(2) in the drip water of lag response, SO(superscript 2- subscript 4) concentration has no significant incrcase during rainfall, but they show a increasing trend during a long-term monitoring;(3) SO(superscript 2- subscript 4) concentration at the stable drip site is low and has no obvious change during wet weason.

本文通过对石花洞洞穴4个滴水点（JG， SH， PL1和PL2）硫酸根浓度近3个水文年的分析测定，结果表明：响应降雨快的滴水点滴水SO(上标 2-下标 4)浓度升高幅度最明显，且滴水SO(上标 2-下标 4)浓度与滴率成指数关系；滞后响应降雨的观测点滴水SO(上标 2-下标 4)浓度雨季升高幅度不明显，但在长期观测期间有明显增加的趋势；对降雨没有响应的滴水点，其SO(上标 2-下标 4)浓度低且雨季没有明显变化。

Methods: Cryogenic temperature bipolar radiofrequecy ablation-cutting operation were applied in the OSAHS patients with presence of turbinate hypertrophy in the inferior turbinate, then to observe clinical symptom、 Sleep monitoring、 prosection of inferior turbinate and Polysomnography.

对OSAHS存在下鼻甲肥大者进行下鼻甲低温射频消融术，治疗后3个月、10个月进行主观症状，下鼻甲形态大小变化、睡眠监测和气道压力滴定对照分析。

In Fuji apple, Starking apple and Feicheng peach, 1-MCP slowed the conversion of TA content and SSC, maintained the ratio of sugar to acid and reduced the flavors loss in later storage time. 1-MCP also reduced the chilling rate and fruit weight loss of Feicheng peach stored at 0℃, but accelerated the decay of Feicheng peach and the detachment of grape berry from peduncle stored at 20℃. The effect of 1-MCP on the decay of strawberry was related to temperature: alleviated at 20℃ and enhanced at 0℃.

在富士、红星和肥城桃果实中，1-MCP处理都延缓了果实可滴定酸和可溶性固形物含量的转化，维持了果实贮藏后期糖酸比，抑制了果实贮藏后期风味的损失。1-MCP处理还减轻了O℃贮藏的肥城桃果实冷害的发生和果实失重，但促进了20℃下肥城桃果实的腐烂和巨峰葡萄的脱粒现象。1-MCP对草莓果实腐烂发生率的影响则与温度有关：20℃下减轻，0℃下加重。
