adrenolytic blocking agent的用法和样例：
- This is most effective if a specific receptor blocking agent is available to counter the effects of a given agonist.
- Covalent binding of antibody is particularly beneficial if a detergent has to be used as the blocking agent of the residual surfaces.
- It seems reasonable to conclude that Toosendanin is a presynaptic blocking agent.
- The performance of block agent effect the effectiveness of blocking,so laboratory and field experiment of polymer gel block agent were done to enhance its blocking effectiveness.
- Use core flow experiments, study the indexes include: block agent injectivity in different permeability formation, the intension after gel forming, shut off rate.
