1) breathing valve
呼吸活门
2) Respiratory gating
呼吸门控
1.
The 4D-CT and respiratory gating technique are effective methods in reducing the image artifact caused by respiratory motions, and which can help to increase the dose accuracy both in tumor and the normal tissues.
基于4D-CT扫描或呼吸门控的放疗计划与执行技术可以实现减小图像伪影,提高靶区和周围正常组织照射剂量的准确性,从而可能使肿瘤组织接受更高剂量或减少正常组织的受照范围,从而提高肿瘤控制率或减少并发症发生率。
3) anal respiration
肛门呼吸
4) Exhalation valve

6) Respiratory activity
呼吸活性
1.
Methods DECB was treated with heat,acid,alkali,baking,organic solvent extracting,micro-organism zymolysis,and then the method of microrespiromete was used to test the respiratory activity.
方法分别将小牛血清去蛋白提取物进行加热、加酸、加碱、烘烤、有机溶剂萃取、接种微生物发酵等方法处理,然后分别用微量呼吸检压法检测呼吸活性。
2.
During the different stage of microspore development, the total respiratory activity(Vt),the cytochrome pathway activity(ρ′Vcyt) and the alternative pathway activity(ρValt) of anther that was on treated wheat plant by GENESIS and on untreated wheat plant by GENESIS were compared.
对小麦小孢子发育的各个时期,经GENESIS处理的和未处理的植株花药的总呼吸活性 Vt 、细胞色素途径呼吸活性 ρ′Vcyt 和交替途径实际呼吸活性 ρValt 进行了比较研究,结果表明,在各时期,处理植株花药的Vt呼吸均低于未处理植株,尤以单核期最为明显;在小孢子减数分裂期、四分体期和单核期,处理小麦植株花药的ρ′Vcyt均明显降低,而在小孢子减数分裂期和四分体期ρValt出现明显升高。
3.
