Based on the original production process, the developed corrosion inhibitor used for polyurethane foaming changes the pH of dialyzate, which is produced from submerging polyurethane foam to water, from acidity into faint alkalinity, so as to inhibit or retard corrosion of the pipeline.

研制成的聚氨酯泡沫用缓蚀剂，在不改变原有生产工艺及发泡参数的基础上，将聚氨酯泡沫浸水析出液的pH值由酸性改变为弱碱性，从而达到抑制或延缓泡夹管腐蚀的目的；采用喷涂聚脉补口技术，有效地提高了现场补口的质量。

This study investigated the mechanisms that induce EMT and the significance of extracellular signal-regulated kinase cascade in this course in vitro.

本文旨在研究酸性成纤维细胞因子对上皮-间质转分化的影响，探讨有丝分裂原激动蛋白激酶的ERK信号传导途径在此过程中的作用，为肾小管-间质纤维化的防治提供理论依据。

A cement resembling putty; made by mixing ferric oxide and boiled linseed oil; is acid resistant.

一种类似油灰的胶泥，由氧化铁和煮沸的亚麻油混合而成，具有抗酸性。

Exclusive non-acid formula takes care of all skin's little problems--pores, flakiness, redness, fine lines.

高级的无酸性配方照顾到肌肤的所有小问题--毛孔，皮肤成薄片状，皮肤泛红，细小纹路。

Fluoride to prevent cavities there are several ways: to hydroxyapatite into fluorapatite difficult to dissolve and reduce enamel in acid in the soluble; to a direct impact on dental plaque and reducing plaque organisms secrete acid capacity; accelerated by acidic substances are due to decalcification of the tooth enamel erosion and mineral parts of recharging it.

氟化物以防止蛀牙，有几种方法：对羟基磷灰石成难溶于和减少酸，可溶性搪瓷；在对牙菌斑产生直接影响，减少牙菌斑生物分泌酸能力；的酸性物质加速是由于脱钙的牙齿釉质侵蚀，它的充电矿产部分。

Cephalotaxine ester of 2-oxo-6-methylheptanoic acid was treated with lithium diisopropylamide and Me O-(1-methoxyisopropyl)glycolate to give a mixture of homoisoharringtonine and its stereoisomers with 56% yield. The four stereoisomers separated by TLC showed identical mass spectra and almost superimposed IR but with different 1H NMR spectra. The configuration of the 2'-C and 3'-C of the four isomers were postulated based upon their 1H NMR spectra as compared with the 1H NMR spectra of isoharringtonine and its stereoisomers.

2-氧代-6-甲基庚酰基三尖杉碱(3)与0-(1-甲氧基异丙基)羟基乙酸甲酯(4)在强碱性试剂二异丙胺锂存在下，起亲核加成反应，反应中间体5在室温用酸性丙酮水解，得到一种新的三尖杉酯类生物碱一一高异三尖杉酯碱(6c)及其立体异构体(6a、6b、6d)的混合物，产率56%、通过制备薄层层析分得这四个立体异构体，它们的1H NMR和异三尖杉酯碱及其立体异构体的1H NMR类似，推定了它们的绝对构型。

These cysts are lined by epithelium with eosinophilic cytoplasm and a hobnail morphology, and there is often ovarian-like stroma.

囊壁由含有嗜酸性胞浆的上皮围成，上皮细胞呈鞋钉状，常常有卵巢样间质。
