采用解吸？内部沸腾两步法强化植物有效成分提取，首先用少量低沸点解吸剂饱和植物组织，以使组织内部的有效成分充分解吸，然后快速加入温度高于解吸剂沸点的溶剂，使植物组织内部的解吸剂迅速被加热至沸腾，强化传质过程。

Adaptive decompressing status monitor based on MC68HC08;2. A new method was put forward for extracting the activity components in the plant by decompressing inner ebullition.

减压内部沸腾法是用少量低沸点解吸剂润湿被提取物料粉末，使其中的有效成分充分解吸，然后加入一定温度的热提取溶剂并迅速减压，使渗透到植物组织内部的解吸剂首先沸腾，强化提取过程。

Even inflect local transmitting heat translate from film boiling to core boiling.

甚至改变局部传热状态由膜态沸腾转变为核态沸腾。

Will the rest of milk is joined saccharic put pot to boiling, in the milk that boiling the Ji Shifen of mix up and milk oar interfuse, put out blaze at the same time and fast agitate comes to mix adequately to be become namely

将余下的牛奶加入砂糖放在锅中煮至沸腾，将调好的吉士粉和牛奶浆混入正在沸腾的牛奶中，同时关掉火焰并快速搅拌至充分混合即成

In the fully developed nucleate boiling zone, the effect of sub-cooling to boiling curve is not great.

在充分发展核态沸腾区域内，过冷度的高低对沸腾曲线的变化影响不大。

The agitation power consumptions in boiling systems decrease uniformly with the increase of agitation speed, whereas the relative power demand (RPD-the ratio of agitation power input of HEDT for gassed system to that for ungassed system and under the same agitation speed) can maintain at a high level for high gas loadings even when the impeller is operating with a high impeller tip speed. The gas hold-up in the boiling system is much lower than that in the cold gassed system, and the gas hold-up in boiling system increases at first and then decreases with the increase of the agitation power consumption per liquid mass P(subscript m. It implies that the boiling three-phase system has a maximum gas hold-up point. The changes of nucleation site of vapour bubble and the character of suspension of the solid particles with the rotational speed of the impeller are responsible for those behaviors mentioned.

在沸腾条件下，搅拌功率消耗随着搅拌转速的增加有所下降，但HEDT桨具有较高的载气能力，即使在高叶端线速度下，相对功率消耗仍能保持在较高的水平；沸腾体系的气含率随单位质量流体输入功率的增加表现出先增后减的规律，即存在气含率的极大值，蒸汽成核位置和固体颗粒悬浮特性随搅拌功率增加而改变是造成上述行为的主要原因；沸腾体系中的气含率远远低于常温通空气体系。
