凝固点

The test result showed that the pour point of Jianghan crude oil might depress from 28 ℃ to 13 ℃ when styrene∶maleic anhydride∶octadecyl acrylater was 1∶3∶3, preheated temperature of the crude oil was 60 ℃, and addition of the terpolymer was 300 mg/L.

研究表明，当苯乙烯、马来酸酐、丙烯酸十八烷基酯三种单体摩尔比为1∶3∶3，原油预热温度为60 ℃，三元共聚物在江汉原油中加量为300 mg/L时，此三元共聚物可使江汉原油的凝固点从28 ℃降到13 ℃。

The ice/liquid mixtures of the coolant and the sample solution were respectively added in the Dewar bottle and the sample container to precool for 2～3 hours under stirri...

实验结果显示，改进的凝固点降低法测定摩尔质量实验装置结构合理，其测定误差可控制在±0.001℃以内。

Although the discipline of cryptography is at least two thousand years old, its algorithmic and mathematical foundations have recently solidified to the point where there can now be talk of provably secure cryptosystems.

虽然纪律加密至少二千年岁，它的算法和数学基础，最近凝固点那里现在可以谈的可证明安全加密系统。

Castor oil is an important industrial raw material, and the ricinoleic acid it contains has the characters of high viscocity, large proportion, higher burning point, lower freezing point, etc, with wider industrial utilities and higher economic value, castor oil has been listed as one of six strategic materials by US.

蓖麻油是重要的工业原料，其含有的蓖麻酸，具有粘度大、比重大、燃点高、凝固点低等性质，具有广泛的工业用途和极高的经济价值，美国已把蓖麻油列为六大战略物资之一。

As you can see from the graph the motor slightly overshoots the speed set point of 50 radians per second before quickly returning to this value with minimal steady state error.

您能从图表看马达在快返回轻微地超越速度凝固点50个弧度每秒到这价值之前以最小的稳态误差。

Diagram shows the experiment on changing the state of water with 2 process, boiling and freezing.
