The best technology of purified lycopene oil resin was, lycopene oil resin:Trimethylene glycol:Potassium hydroxide:Water 3.5:4.5:1.5:1.5,saponification temperature 70℃, saponification time 2h. The content of lycopene is 3.4%, extraction rate is22.48%.

较优的工艺条件为，番茄红素油树脂：丙二醇：氢氧化钾：水的比例为3.5：4.5：1.5：1.5，皂化温度为70℃，皂化时间2小时，所得番茄红素的含量为3.4％。

Some additives that could enhance the enzyme stability were screened through single factor experiments, such as 5 mmolL^(-1) Ca(superscript 2+), 20 mgmL^(-1) trimethylene glycol-single methyl ether, 0.01% 4-formyl phenyl-boron dihydroxide, 1% glycerine.

通过单因素实验得出了对碱性蛋白酶稳定效果较好的几种保护剂：5mmolL^(-1) Ca(上标 2+)；20mgmL^(-1)微胶粒抑制剂丙二醇－单甲醚；0.01%可逆蛋白酶活性抑制剂4－甲酰苯基硼酸；1%甘油。

The different enzyme protecting agent had effected on the liquid alkaline protease under the dissimilar condition. Taking the living rate of enzyme as the target, we obtained one high effective alkaline protease stabilizing agent formula through orthogonal experiments as following: 5 mmolL^(-1) Ca(superscript 2+), 15mgmL^(-1) trimethylene glycol-single methyl ether, 0.015% 4-formyl phenyl-boron dihydroxide, 1% glycerine.

在此基础上，进行L13(3^7)正交实验，以相对酶活率为指标，考察了不同酶活性保护剂在不同条件下对液体碱性蛋白酶活力的影响，筛选到一种优质高效的碱性蛋白酶稳定剂配方为：5mmolL^(-1) Ca(上标 2+)，15mgmL^(-1)丙二醇－单甲醚，0.015% 4-甲酰苯基硼酸，1%甘油。

It is easy soluble in water,propylene glycol and glycerol etc,unsoluble in ether,benzene and chloroform.

易溶于水、丙二醇、甘油等，难溶于醚、苯、氯仿，受强热可水解为肌醇和磷脂。

The refills contain just nicotine and propylene glycol, there is no tobacco.

该填充物含有的尼古丁和丙二醇，没有烟草。

The present invention features that one kind of aerobiota is first used to ferment glucose, saccharified starch liquid, enzymolyzed cellulose liquid and other carbohydrate to produce glycerin, and one other kind of anerobic microbe is then used to convert glycerin into propylene glycol.

本发明的特征在于首先使用一种好氧微生物菌种发酵如葡萄糖、淀粉糖化液、纤维素酶解液等碳水化合物产生甘油，进而再通过另一种厌氧微生物菌种将甘油转化为1，3－丙二醇，其中第一步发酵所得到的发酵液可离心或过滤除去菌体，清液可直接进入第二步发酵或者经浓缩后作为第二步发酵的批式流加液，部分菌体可在连续发酵时循环使用；第一步发酵液也可不离心经灭菌后再进行第二步发酵。

Although the 5% solution seems to be more effective, it is also stickier due to it＇s higher propylene glycol content (the 2% solution contains more alcohol).

虽然5%的米诺地尔看上去更有效果，但是它更粘，因为高浓度丙二醇溶液（假如浓度是2%的话就包含更多的酒精）。

Thirdly, the final product MPO was synthesized in a self-designed bubble tower reactor under atmospheric pressure in presence of Pd/γ-Al_2O_3 catalyst.

采用Pd／γ-Al_2O_3作为加氢催化剂，常压下在自制的塔式加氢器中合成出了目的产物2-甲基-1，3-丙二醇，采用IR、GC900气相色谱仪及QP-5000型气质联用仪等技术确证了本工艺合成的目的产物MPO。

Methods: 60 freshly extracted , single-rooted premolars were randomly divided into two experimental groups (cinnamic aldehyde, gallnut decoction) and four control group (FC group, calcium hydroxide mixed with propylene glycol group, negative the control group and positive control group),.

标本牙去除牙冠部及根尖部，留取6mm长牙根，50颗牙建立粪肠球菌根管感染模型后，20颗牙根管内分别放置桂皮醛、五倍子水煎剂，另30颗感染根管放置FC、氢氧化钙丙二醇糊剂和生理盐水。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
