Methods:All the 40 Winstar rats were divided into four groups:group A:the rats were fed with normal diet,group B:the rats were fed with only high|cholesterol diet(no vitamin D3),group C:the rats were treated with one intramuscularly injection of vitamin D3(300 000 U/kg) and were denudated of endothelium,followed by high|cholesterol diet,group D:the rats were treated with 5% chitosan added into the diet besides treatment as group C.Ninety days later,the formation of atherosclerosis plaques and the activities of nitric oxide synthase in aortas in the four group rats were investigated.

40只Wistar大鼠均分为：A组；B组：饲以高脂饲料（不含维生素D3）；C组：一次性给予大鼠维生素D3（30万U/kg体重）肌肉注射，以球囊损伤主动脉内皮和饲以含维生素D3（1.25×106U/kg）的高脂饲料；D组在C组的基础上饲料中加入5%壳聚糖。90 d后检测主动脉动脉粥样硬化斑块形成及NOS的活性。

This plan would have succeeded if the four companies of the English guards and the brave Belgians of Perponcher's division had not held the position solidly, and Wellington, instead of massing his troops there, could confine himself to despatching thither, as reinforcements, only four more companies of guards and one battalion from Brunswick.

Four aspects are studied in this paper: the study of non-linear syllable theory of the analysis ofdengyunxue of the syllabic structure of Chinese character, the study of the distinctive feature theory of the four types of the articulation of initials, the study of the markedness theory of the devoicing of the fully voiced initials and the study of the feature geometry theory of the correlates between the devoicing of the fully voiced initials and tonal change. Through our studies, conclusions can be drawn as follows:(1) Contemporary phonological theories can be used to elucidate the principle of Chinese dengyunxue;(2) Contemporary phonological theories can be used to explain the historical phonetic change of Chinese;(3) Different theories and methods of contemporary phonology should be applied to deal with different problems of Chinese phonology;(4) The application of contemporary phonological theories to the study of the historical phonetic change of Chinese is helpful to test and verify the universalizability of these theoretical hypotheses

通过对等韵字音结构分析的非线性音节理论研究、声纽四等的区别特征理论研究、全浊声母清化的标记理论研究和浊音清化与声调演变相互关系的特征架构理论研究等四项初探，揭示了：（1）当代音系理论可以阐明汉语等韵学学理；（2）当代音系理论可以解释汉语历史音变现象；（3）不同的汉语音韵问题，应该用不同的当代音系理论方法来研究；（4）当代音系理论在汉语历史音变研究中的运用，有助于验证其理论假设的普适性

Bidentis were studied by adopting indoor bioassay. The results showed that the volatile matter of F. bidentis had not allelopathy to four receptor plants. The eluviated matter inhibited seedling growth of cotton obviously, the inhibition ratio of root and stem were 6.29% and 10.42% respectively. The aqueous extract of litterfall and root exudates had different inhibition to four receptor plants, The synthesis effectof all treatments was significantly greater than eluviated matter treatment except for B3 of the aqueous extract of root exudates, such as the synthesis effect of all treatments (A1, A2, A3, B1, B2, B3 and eluviation) were 44.74, 29.37, 14.5, 31.54, 16.52, 3.55, 1.48 respectively.
