A HPLC method was used for analyzing the changes of eight major constituents, namely gallic acid, paeoniflorin sulfonate, catechin, paeoniflorin sulfonate, albiflorin, paeoniflorin, benzoic acid, pentagalloylglucose and benzoylpaeoniflorin, with the three processing procedures of decorticating, boiling and fumigating by burning of sulphur.

采用高效液相色谱法分别分析经去皮、水煮和硫磺熏制3个不同加工阶段后，白芍中没食子酸、儿茶素、芍药苷亚硫酸酯、芍药内酯苷、芍药苷、苯甲酸、五没食子酰基葡萄糖和苯甲酰芍药苷等8种主要化学成分的变化。

Internal factors include the chemical composition of metals, metal the microstructure changes such as dynamic recovery and dynamic recrystallization, such as work hardening.

内部因素主要包括金属的化学成分、金属的微观组织变化如动态回复和动态再结晶、加工硬化等。

In order to select monomer of Chinese herbal polysaccharide with better immunity, four CHPs, APS, ABPS, IRPS and DOPS at six doses were added in the splenic lymphocyte of chick in vitro, and cultured 48 h. The splenic lymphocyte proliferation was determined with the MTT method.

为了筛选免疫增强作用较好的单味中药成分，将6种浓度的黄芪多糖、牛膝多糖、板蓝根多糖、山药多糖等4种中药多糖分别加入到体外培养的鸡脾脏淋巴细胞中，培养48h后，用MTT法测定淋巴细胞增殖的变化。

Linear frequency-modulated signal that is often applied in radar, sonar and communications system is nonstationary signal, in which the frequency varies with time.

应用于雷达、声纳和通信等信息系统中的线性调频信号是非平稳信号，即频率成分是随时间变化的。

The new approach based on bio-impedance technology is influenced by many factors such as gastric secretion, components of test meal. But the non-nutrient fluid that has low electric conductivity and has no impact on stomach can be employed to investigate the relationship between the emptying curve of impedance and gastric volume.

胃阻抗法虽然受到胃液分泌、试验餐成分等多种因素的影响，但是选用对胃内影响较小、电导率低的非营养性液体可以获得阻抗信号和胃容积变化的对应关系。

There also appeared more flexible word order, some new grammatical categories, such as gender, number and aspect, some new sentence structures and more precise grammar responsive to the needs of the times.

句法方面出现了文言、古白话句法的沉淀，以及新、旧句法成分合并而形成的句法&杂合&现象，同时还有&性数体&等语法范畴的生成与变化、主语的频繁使用以及新结构的产生，出现了句法严密化、情感化的发展趋向。
