陈化

The content of carotenoid and petroleum ether extract reduced at three months of aging and then increased.

类胡萝卜素和石油醚提取物含量在陈化三个月时降低，之后上升。

It was found that the solvent type affected the gel point, the different amount of water addition could alter the structure of condensation polymer, the varying of ageing time influenced the growth of grains and the calcination temperature had great effect on phase structure and grain size.

发现不同的溶剂类型能够改变胶凝时间，加水量的多少会影响醇盐水解缩聚物的结构，陈化时间的长短直接改变晶粒的生长状态，煅烧温度的变化对粉体的相结构和晶粒大小有重要的作用。

Time are tested under different kinds of stress for nitrided and un-nitrided specimens made from 35CrMo steel. The testing time ranges from 70 to 80 hours. The following equations are regressed from the tested curves: Un-nitrided specimens:〓 Nitrided specimens:〓 The above equations are consistent with the first stage theory for creep.

为此本文通过实验，测试了35CrMo钢渗氮和未渗氮两种试样在500℃时不同应力情况下的应变随时间的变化曲线，实验时间为70-80小时，将测得的曲线回归出以下方程：未渗氮样品：〓渗氮样品：〓以上方程符合蠕变的第一阶段陈化理论公式。

The styrene-acrylate spheres were coated with the TiO2 colloidal particles via electrostatic effect and hydrogen bond interactions with the increase of aging time, thus the film-forming capability of the solution was changed. The poor film-forming capability results in the formation of the porous structure with dense, homogeneous island morphology. Then the TiO2 porous films with dense pores can be obtained after two coating-dissolving cycles.

结果表明，TiO2溶胶与苯丙乳液混合后，陈化时间的延长有利于TiO2胶粒通过静电、氢键作用在苯丙乳液粒子表面形成吸附层，从而改变涂膜液的成膜性，形成较为密集、且均匀分布的岛状多孔结构，在此基础上经两次涂膜，即可获得具有致密孔洞的TiO2多孔薄膜。

Our country produces fuel alcohol in grain of northward pilot also use Chen Hua and corn.

我国在北方也试点使用陈化粮和玉米生产燃料乙醇。

The raw materials are post-fermented and processed into loose tea and pressed tea.

其中包括自然陈化的普洱生茶和人工发酵的普洱熟茶。

The preparation procedure is as following: purification and assay for purity of neptunium, preparation of neptunium nitrate solution, making solution for ageing, subpacking the solution to ampoules, fire sealing, weighing for earch ampoule, homogeneity test, stability test, and certification.

以工厂的氧化镎作原料，经原料提纯→纯度鉴定→配成硝酸溶液→放置陈化→分装→火封→称重→均匀性检验→稳定性检验，最后进行定值。

The second key point is that the aging process.

第二个关键点是，陈化过程。

The results showed that(1) the fungi can produce high quantity laccase up to 1 920 U/L on 15 days;(2) its metabolites including terpenol and sesquiterpene alcohol were all natural VOCs of tobacco;(3)the zymotic fluid applied on cured tobacco can apparently reduce the lignin of cured tobacco by 8% and the smoking quality .

采用木质素含量较高的烟梗为筛选材料，分离筛选到一株具有降烟草木质素功能的真菌，并测定了该菌的产酶活性、代谢物中挥发性成分及粗酶液在烟草快速陈化中的作用。

The synthesis condition of PSFCS were: Fe-to-Si mol ratio being 2, silicic acid activation pH being 2, silicic acid activation time being 30~40 minutes, ageing time being 2~2.5 hours.

PSFCS的合成条件：Fe/Si摩尔比为2，硅酸活化pH值为2，硅酸活化时间是30～40 min，陈化时间是2～2.5 h。

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。
