１０６名ＨＢｓＡｇ阳性母亲的婴儿，用１０μｇ×３剂和以０、１、６月程序接种乙肝疫苗．于接种后１年检测时，对其中抗－ＨＢｓＳ／Ｎ值＞２．１的８７人，及免疫接种失败者ＨＢｓＡｇ阳性１９人和未接种乙肝疫苗而ＨＢｓＡｇ阳性婴儿２８人作了为期９年随访研究．在抗－ＨＢＳ阳转者抗－ＨＢＳ水平的动态变化观察中未发现ＨＢｓＡｇ阳转者．至９年时仍有２９人（４４．６％）抗－ＨＢＳ水平＞２．１，说明疫苗的免疫源性和９年的免疫效果是好的．ＨＢｓＡｇ阳性１９人与未接种疫苗而ＨＢｓＡｇ阳性２８名婴儿同时追踪结果，仍持续ＨＢｓＡｇ阳性，提示这些婴儿系宫内或围产期感染所致。
106 infants of HBsAg positive mothers were challenged with 10 μg x 3 doses and vaccinated with hepatitis B vaccine for 0, 1, or 6 months. At 1 year after inoculation, 87 patients with anti-HBs / N value> 2.1, 19 HBsAg positive patients with failed immunization and 28 HBsAg positive infants without hepatitis B vaccine were followed up for 9 years the study. HBsAg positive mothers were not observed in the dynamic changes of anti-HBS level in anti-HBs positive patients. At 9 years, 29 (44.6%) still had anti-HBS levels> 2.1, indicating that the immunogenicity of the vaccine and the 9-year immunization benefit were good. 19 HBsAg-positive and non-vaccinated HBsAg-positive 28 babies also tracked the results at the same time, still continue HBsAg-positive, suggesting that these infants were intrauterine or perinatal infection caused.

对《论衡》中的助动词在穷尽性数量统计的基础上做细致的描写，并在此基础上分析其语义，比较不同类助动词、不同的个体助动词在句法结构、语义等方面表现出的差异，展现《论衡》助动词的基本面貌。同时也注意在共时描写的同时与先秦时期的助动词系统做适当的历时比较，借此考察《论衡》中助动词的发展变化情况。
