At the same tine 3 regions were selected from observation contents of photograph, measuring with the densimeter. And the objective method was used to test and verify the effect of evaluation with the subjective method. 用客观法对胸片观察内容有代表性的3个点实施密度计测量,验证主观法评价照片质量效果。
In order to compare the sensitivity of ABC-ELISA test with that of rou-tine ELISA test in assaying plague, the two kinds of tests have been used for assaying the particulate and soluble antigen of plague in this article. 为比较ABC-ELISA法和常规ELISA检测鼠疫FI抗原的灵敏度,本文用两法对鼠疫颗粒性抗原和可溶性抗原进行平行检测以资对比。
When we test splice loss and loss by Optical Tine Domain Reflector, we may find that the selection of pulse width influences the precision of test, the linearity approximative method also influences the test result. 在利用OTDR测试接续损耗和损耗时,脉宽的选择影响测试的准确性,线性近似法的选择对测试结果也有明显影响。
