“干清粪”系统猪粪快速堆肥过程中添加剂对甲烷、氧化亚氮和氨气排放的影响(英文)

研究目的:在"干清粪"系统猪粪堆肥过程中,不同添加剂(玉米秸秆、锯末和蘑菇渣)处理对甲烷、氧化亚氮和氨气排放的影响。创新要点:将不同的添加剂(玉米秸秆、锯末和蘑菇渣)应用到快速堆肥系统中进行堆肥,测定了猪粪堆肥过程中甲烷、氧化亚氮和氨气的排放规律,为国内猪粪堆肥的应用提供理论指导。重要结论:玉米秸秆作为添加剂能增加猪粪堆肥过程中氧化亚氮的排放;蘑菇渣添加剂增加了堆肥过程中甲烷的排放,然而减少了氧化亚氮及氨气的排放;锯末处理能增加堆肥过程中氨气的排放。添加剂能显著影响堆肥过程中氮素的损失。

The relationship between bilingual proficiency and self-esteem

Proposing that bilingual proficiency should produce a more favorable attitude toward bilingualism and should enhance one's self-esteem, the authors compared 57 bilingual and 67 unilingual students from grades 9, 10, and 11, measuring their opinions about bilingualism and their self-esteem. The bilingual students are substantially more favorably disposed toward bilingualism than the unilingual students are. On the Janis-Field scale of self-esteem, the bilingual students show greater self-esteem than the unilingual students. The largest differences between the groups are on questions that measure self-confidence and social ease; differences are less pronounced on questions about self-worth and about shyness. We speculate that bilingual proficiency offers some psychological advantages to students who achieve it.
