Aqueous extract of cotton has allelopathic effect on Raphanus sativus, Brassica campestris, Lactuca indica, Brassica campestris, Echinochloa crusgall, Setaria viridis and Abutilon theophrasti and its inhibition effect gradually strengthens with increasing concentration. Aqueous extracts from stems, leaves and roots of cotton inhibit or accelerate seed germination and seedling growth, and activity of enzyme of seedling root of cotton. While aqueous extracts from stems and leaves of cotton are 0.02 gmL^(-1), root length, shoot length, lateral root number and dry weight of cotton respectively increase by 10.3%, 3.1%, 22.9% and 2.4% over the control. The above mentioned indexes are lower than the control by 34.4%, 39.2%, 40.6% and 19.0% respectively as the aqueous extracts are 0.1 gmL^(-1). At the same time, root activity and SOD activity decrease by 38.2% and 36.7%, while POD activity and MDA content increase by 52.3% and 36.5%. Growth indexes of plant receptors increase at low concentrations but decrease at high concentrations of aqueous extracts. The allelopathic effect of aqueous extract of stems and leaves is stronger than that of root.

结果表明：棉花植株水浸提液对萝卜、白菜、莴苣、油菜、稗草、狗尾草、苘麻均具有化感效应，随着作用浓度增加，抑制效应逐渐加强；棉花茎叶和根系水浸提液对棉花种子萌发、幼苗生长、幼苗根系活力、根系酶活性有抑制或促进作用，当茎叶浸提液浓度为0.02 gmL^(-1)时，棉花根长、苗高、侧根数、干重分别比对照增加10.3%、3.1%、22.9%和2.4%，当浓度为0.1 gmL^(-1)时，上述指标与对照相比分别降低34.4%、39.2%、40.6%和19.0%，而根系活力、SOD活性比对照降低38.2%、36.7%，POD活性、MDA含量较对照增加52.3%和36.5%，不同浓度棉花植株水浸提液对棉花生长呈现"低促高抑"的规律，且茎叶浸提液作用效应大于根系浸提液。

The area ratios of 980/1022, 980/1047,(980+1047)/1022 and 980/(1022+1047) cm^(-1) were decreased as the degree of acetification increased which indicated that acetification induced a decrease of crystallinity of starch. And the crystal structure changed from A-type to V-type. For the cross-linking of POCl3, the area ratios of 980/1022, 980/1047,(980+1047)/1022 and 980/(1022+1047) cm^(-1) were also decreased as the degree of cross-linking but the decrease was little compared to that of acetification. The result indicated that cross-linking of POCl3 had little effect on the starch crystal structure.

随着醋酸酯化取代度的增大，980/1022、980/1047、(980+1047)/1022和980/(1022+1047)的相对峰面积的比值均呈现下降趋势，表明醋酸酯化改性会导致淀粉结晶程度降低，结晶形态从A型转变为V型；随着交联度的增大，980/1022、980/1047、(980+1047)/1022和980/(1022+1047)的相对峰面积比值均呈现下降趋势，但下降程度较小，表明三氯氧磷交联对淀粉结晶结构影响不明显。

The mismatch or match segments of gated DISA imaging were defined by two experienced physicians of nuclear medicine who are not aware of clinical data. Regional wall motion score were interpreted as 16 segments system by American Echocardiography Association in 5 score: 0=regional wall motion normal; 1=slight decrease of regional wall motion; 2=severe decrease of regional wall motion; 3=dyskinesia; 4=akinesia.

门控DISA SPECT结果，由两位核医学科医生采用双盲法判断心肌灌注／代谢匹配情况，并根据美国超声心动图学会16段法分段，以5分法判断各节段局部室壁运动记分：0分=局部室壁运动正常；1分=运动轻度减低；2分=运动明显减低；3分=无运动；4分=反向运动。

Empirical evidence on the relationship between "tunneling" and earnings management suggests that,"tunneling" would decrease the transparency of the whole economy, and then decrease the capital allocation efficiency of capital markets, finally delay the economic growth. Under the conditions that investor protection is very poor and ownership is concentrated, listed companies in Chinese stock market are always agencies of controllers to get private benefits at the expense of minority shareholders.

正出于此，本论文以我国股票市场特殊的制度背景为出发点，在参考Bebchuk（1999）模型的基础上，发展了一个理论模型来证明，在投资者保护薄弱和所有权集中的制度背景下，控股股东具有充分动机来侵占少数股东利益获取控制权私利。

Therefore, based on documents reports, through contrastive observation of 20-month-old natural senile mice, this study has confirmed that the anaplasia of subacute senile model mice was obviously similar to the features of 20-month-old naturally physiological senile mice. Mice in both two groups displayed dull color patterns, slow movements, insensitive responses and decrease of growth rates of body weight; hepatic and brain tissues in the mice presented senile features of sero-enzyme such as decrease in SOD activity, increase in content of lipid perhydrides and so on.

为此，本研究在文献报道基础上，通过与20月龄自然老化鼠的对比观察，证实：亚急性衰老模型鼠的退行性变化与20月龄自然生理性老化鼠特征的相近之处鲜明可见。2组均出现毛色暗淡，少有光泽，动作迟缓，反应不灵敏，体重增长率下降；肝、脑组织出现SOD活力下降，脂质过氧化物含量增高等血清酶学的老化特征。
