按Hopper&Thompson(1980)提出及物性假说中判断定及物性的特征,汉语动词重叠句的及物性表现出不均衡性,在涉及主语和动词的特征上,动词重叠式表现出高及物性;在涉及宾语及现实性特征上,动词重叠式表现出低及物性。本文认为后者是及... 按Hopper&Thompson(1980)提出及物性假说中判断定及物性的特征,汉语动词重叠句的及物性表现出不均衡性,在涉及主语和动词的特征上,动词重叠式表现出高及物性;在涉及宾语及现实性特征上,动词重叠式表现出低及物性。本文认为后者是及物性的核心特征,因此汉语动词重叠式应该是低及物性的句式。在语篇上,动词重叠式在事件线索和情景设置两个参数上都表现出构建背景化信息的倾向。 展开更多

According to relativistic dynamics, the super-luminal signal transmission is impossible. The present quantum theory is therefore consistent with the relativity and the causality. 展开更多

Aconite is a valuable drug and also a toxic material, which can be used only after detoxification processing. Although traditional processing methods can achieve detoxification effect as desired, there are some obvious drawbacks, including a significant loss of alkaloids and poor quality consistency. It is thus necessary to develop a new detoxification approach. In the present study, we designed a novel one-step detoxification approach by quickly drying fresh-cut aconite particles. In order to evaluate the technical advantages, the contents of mesaconitine, aconitine, hypaconitine, benzoylmesaconine, benzoylaconine, benzoylhypaconine, neoline, fuziline, songorine, and talatisamine were determined using HPLC and UHPLC/Q-TOF-MS. Multivariate analysis methods, such as Clustering analysis and Principle component analysis, were applied to determine the quality differences between samples. Our results showed that traditional processes could reduce toxicity as desired, but also led to more than 85.2% alkaloids loss. However, our novel one-step method was capable of achieving virtually the same detoxification effect, with only an approximately 30% alkaloids loss. Cluster analysis and Principal component analysis analyses suggested that Shengfupian and the novel products were significantly different from various traditional products. Acute toxicity testing showed that the novel products achieved a good detoxification effect, with its maximum tolerated dose being equivalent to 20 times of adult dosage. And cardiac effect testing also showed that the activity of the novel products was stronger than that of traditional products. Moreover, particles specification greatly improved the quality consistency of the novel products, which was immensely superior to the traditional products. These results would help guide the rational optimization of aconite processing technologies, providing better drugs for clinical treatment. 展开更多
