The bacteriostatic effects, action mechanisms and antimicrobial spectrum of the strains were tested. After 5 days of culture, a bacteriostatic belt of 6.9-9.67 mm in width was observed on the culture plate, and the inhibitory activity maintained for 10 d. Prefiltration fermentation of the strains P1 and P5 could significantly inhibit conidial germination of the pathogen, with inhibitive rate ranging from 97.51% to 98.12%. The action might be realized by inducing hyphal deformity, bioplasm concentration, conidial germination inhibition and distorting germ tubes of conidia.

通过对其抑菌效果、机制和抗真菌谱进行测定，结果表明，P1、P5和葡萄灰霉病菌对峙培养5 d后，均产生明显的抑菌带，抑菌带宽度为6.90～9.67 mm，培养10 d后，仍然保持稳定的抑菌效果；P1、P5的发酵原液对葡萄灰霉病菌孢子萌发具有显著的抑制作用，抑制率为97.51%～98.12%；P1、P5对病菌的作用机制表现为使病菌菌丝畸形、原生质浓缩、菌丝断裂、抑制病菌分生孢子的萌发、导致孢子芽管扭曲。

Mechanism of carbon combustion reaction is deduced based on the flame temperature produced by coke burning in bloomery abdomen.

本文根据炼铁高炉炉腹内焦炭燃烧产生的火焰温度推测碳燃烧反应的机理为：第一步，氧气吸收光子形成游离态氧原子，每摩尔氧气吸收 1mol光子；第二步，碳与游离态氧原子作用生成CO ，每生成 1molCO发出 1mol光子；第三步，CO与氧分子作用生成CO2 ，该步骤既不吸收光子，也不发出光子。

Using the model of CTX mice,on"Dazhui","Shenshu"and"Zusanli"by crude herb moxibustion with cantharis anhydro preparation,examine the effect on the number of karyocyte of bone marrow and WBC and spleen index and the production ability of GM CSF by abdominal cavity macrophage.

Results The extract remarkably inhibited the contraction caused by histamine and acetylcholine, as well as the ovalbumin sensitized allergic constriction of isolated ileum smooth muscle of guinea pigs. It could inhibit the increase of capillary permeability induced by acetic acid in mice, inhibit the mice paw edema produced by carrageenin and reduce the production of PGE 2 in inflammatory tissues.

结果：辛夷二氯甲烷提取物对组胺、乙酰胆碱（Ach引起的豚鼠离体回肠收缩具有显著的抑制作用，并能抑制卵白蛋白所致的豚鼠离体回肠过敏性收缩，对HAc引起的小鼠腹腔毛细血管通透性增高具有抑制作用，能显著抑制角叉菜胶引起的小鼠足肿胀，并减少前列腺素E2（PGE2）在炎症组织中产生。

This dissertation studied the overcompensatory responses of cotton,Gossipium hirsutum L. plants to leaf loss, square loss and cell sap lossand the changes in some physiological and biochemical contents with timein the case of overcompensation. The artificial defoliation, early squareremoval and aphis colonization were used as three types of simulated ornatural herbivory. The target of this study is to elucidate thephysiological mechanism of cotton plant overcompensation for insectherbivory.
