AFTN demulsifiers of polyoxypropylene-polyoxyethylene amine ethers are synthesized from oxypropylene, oxyethylene and amine under a lower pressure less than 0.5 MPa and in the presence of the KOH catalyst, oxypropylene polymerizes at (130±5)℃ temperature, and oxyethylene polymerizes at (120±5)℃ temperature.

以伯胺为起始剂、氢氧化钾为催化剂，分别以环氧乙烷［开环聚合温度为(120±5)℃］和环氧丙烷［开环聚合温度为(130±5)℃］为单体，在0.5 MPa以下合成AFTN系列嵌段聚醚型破乳剂。

Kelch-like ECH-associated protein-1 (Keap1) normally sequesters Nrf2 in the cytoplasm in association with the actin cytoskeleton, but upon oxidation of cysteine residues Nrf2 dissociates from Keap1, translocates to the nucleus and binds to ARE sequences leading to transcriptional activation of antioxidant and phase II detoxifying genes.

在正常情况下，Kelch样环氧氯丙烷相关蛋白-1 (Kelch-like ECH-associated protein-1， Keap1)可将Nrf2与肌动蛋白细胞骨架一起收集在细胞质内，但是在半胱氨酸残基发生氧化的情况下，Nrf2和Keap1脱离，进入细胞核并与ARE结合，从而激活多种抗氧化基因和II相解毒基因的转录。

在正常情况下，Kelch样环氧氯丙烷相关蛋白－1(Kelch-like ECH-associated protein-1， Keap1)与Nrf2耦联，并与肌动蛋白细胞骨架结合被锚定于胞浆，但是在半胱氨酸残基发生氧化的情况下，Nrf2和Keap1解耦联，进入细胞核并与ARE结合，从而激活多种抗氧化基因和Ⅱ相解毒酶基因的转录。

Light-coloured varnishes were prepared by etherification of urushiol-formaldehyde condensates with epichlorohydrin. They gave clear paint films in pale colour. The varnishes blended well with various pigments and exhibited excellent properties similar to those of the original Chinese lacquer -"the monarch of the coating". No vesicating action on human body was observed.

The multi-layer wire mesh structure on the premixed gas of acetylene/air and propane/air explosion has been studied.

研究了多层丝网结构对乙炔/空气混合气体和丙烷/空气混合气体燃烧爆炸的抑制作用。

DME can also replace the use of acetylene gas as a cutting, instead of using propane as a propellant agent.

二甲醚也可以代替乙炔作为切割气使用、代替丙烷作为抛射剂使用。

A novel chiral block copolymer PCys-b-PPO-b-PCys bearing Leucine in the side chain was synthesized for the first time.

These SalenAlQ complexes were employed in the cycloaddition of propylene oxide with carbon dioxide to catalyze the reaction.

将合成的SalenAlQ配合物用于催化活化CO_2与环氧丙烷进行环加成反应。

The way this burner system melts metal is simply by pushing the flame exit port up against the hole in the furnace which ordinarily would hold the propane burner (or air blast on a charcoal furnace).

这种燃烧器的方式系统的金属熔体的火焰推出境口岸打击在炉内的通常会举行一个木炭炉的丙烷燃烧器。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
