It shows that the absorption of cu and pb for clover tend to increase gradually with the increased concentration of relevant elements in soil under experiment , but cu and pb display obvious restraining effect 结果表明，生长一个月左右的三叶草对铜和铅的吸收在实验条件下均随土壤中相应元素浓度的增加而增加，但铜和铅之间存在着明显的拮抗作用。
5mg . kg - 1 respectively , zn concentration decreases in pileus when other hms were added , cu , pb , cd , concentration increasion in pleurotus ostreatus , the transformation and distribution is higher than single element , cd > zn > cu > pb 菌盖中锌随着铜、铅、镉的加入而减少，表现为拮抗作用；但当其他重金属元素存在时，平菇吸收富集铜、铅、镉皆表现为协同作用。
Posaconazole has significant in vitro activity against a wide range of fungi , including aspergillus species , the authors explain , but little is known about its clinical effectiveness and safety in patients with invasive aspergillosis 泊沙康唑在体外实验中对多种真菌有拮抗作用，包括曲霉菌属，该文章作者解释道，但其对侵袭性曲霉菌病患者的临床疗效及安全性尚不清楚。
The chances of heavy metal into the plant cell were reduced and stress alleviated . ultrastructural observation of leaf cells of myriophyllum verticillatum linn , showed that la3 + coule alleviate the injury of cell structure produced by cr6 + 对元素含量的测定表明，稀土元素降低了植物对重金属的富集量，两者表现出拮抗作用，减少重金属离子进入植物叶片细胞的机会，从而减轻了毒害作用。
The diameter of the antimicrobial circle could reach 30 ~ 32mm in the test of e . coli by wst22 , and the diameter of the antimicrobial circle could reach 20mm in the test of salmonella enteritidis by sc42 . the others had the different resistance on the pathogenic bacteria 其中wst22对大肠杆菌的抑菌圈直径可达30 32mm ， sc42对沙门氏菌的抑菌圈直径达20mm以上，其余的两株光合细菌也分别在不同程度上对致病菌有拮抗作用。
The strain and its metabolites are identified . the results show that the culture has a broad antimicrobial spectrum against some gram - negative and gram - positive bacteria , and moulds , especially against e . coli , bacillus cereus , and staphylococcus aureus 研究证实，分离出的r21 - 4具有广谱抗菌作用，对革兰氏阴性菌、革兰氏阳性菌、真菌都有一定的拮抗作用，特别是对大肠杆菌、金黄色葡萄球菌、蜡状芽孢杆菌抗菌作用较强。
Results indicate that the capsaicin was evidently active in inhibiting both the bacteria and the fungi and showed strong inhibitory effects on these pathogens in a concentration dependent manner , exhibiting a stronger inhibition to the test bacteria than to the test fungi 结果表明，辣椒碱具有广谱的抗菌范围和较强的拮抗病原菌的活性，且抗菌活性有明显的量效关系，其中辣椒碱对供试细菌的拮抗作用远大于对供试真菌的作用。
After hundreds of practices , all data show the excellent characters of ke yang ling , especially suitable to be used as an antioxidant for premixes containing trace elements as cu , fe , zn , mn , thus solves the antagonism from catalytic oxidation arising from the incompatibilities between vitamins and trace elements 经过多次实践，证明克氧灵的性能优异，特别适用于添加铜、铁、锌、锰等微量元素的预混料中作催化的拮抗作用这一难题。
The other 15 peptides were classified into 2 groups , each group sharing a different consensus sequence that might bind a different site of the target . one peptide of each group was chemically synthesized and added to the rdrp reaction system . we found that one peptide refrained the activity of rdrp 自2组结合肤中各选择1个环肤分子用化学方法合成，将合成肤加入rdrp反应体系后，其中1个环肤分子对rdrp活性表现明显的拮抗作用，加入细胞培养中可对den感染细胞产生明显的保护作用。
Among the joint dose experiments , the antagonism of selenium and mercury is the most evident in the rats with 2 : 1 mol - ratio of selenium and mercury but the least in the rats with 1 : 2 mol - ratio of selenium and mercury . the results also showed that there are two essential conditions for good antagonistic effect of selenium and mercury and 1 : 1 mol - ratio relationship of selenium and mercury in the most organs ( liver , gland , spleen , stomach and lungs ) . one is that the content of mercury is more than 100nmol / g , and another is the 2 : 1 dose ratio of selenium and mercury 总体而言，雌性大鼠对硒、汞毒性的拮抗作用与雄性大鼠相比时更为敏感；相同性别的大鼠体内，联合高剂量时硒、汞的拮抗作用最明显，联合中剂量时，拮抗效果相对不明显，而联合低剂量时，拮抗效果最差；联合摩尔剂量比为2 ： 1 ( se ： hg )和汞的积累浓度大于100nmol g ，是大鼠体内大部分组织器官(肝脏、胸腺、脾、胃、肺)中四川大学硕士学位论文硒、汞等摩尔比积累的两个必要条件，同时也是硒、汞的相互作用产生最佳桔抗效果的两个重要前提。
