摘要
分析了电子技术基础实训过程中出现的一些误区和实际问题。如仪器仪表的不正确使用导致的结果错误 ;电路处理与信号处理不当会使实验无法进行 ;不切合实际的理论分析会导致把正确的结果认为是错误的 ;设备的地线不正确处理会造成电路的短接甚至烧毁元件和电路 ;元器件的应用若不考虑非正常情况和故障情况 ,会使电路出现异常等。许多潜在的因素也会影响电路的正常工作。实验中正是通过分析和处理这些误区和问题才能增长实践经验 ,使理论和实践互相促进 。
A few wrong regions and actuality problem were analyzed that arose in basic experimentation course of electronic technique. Example, it conduce error result as error use instruments; as circuit and signal not be handled properly so as to can't progress experimentation; theory assaying that don't conform to reality so as to take valid result for wrong; As ground wire of equipment use error, can conduce short circuit even burn out component and circuit; if application of component don't consider un-normal circumstance and abort circumstance, so as to turn up anomaly to circuit, etc. many latent factor too can affect circuit normal wording. In experimentation, just by means of assay and handle these wrong regions and problem, make practical experience was increased, and make theory and practice each other accelerate, and collectively heighten.
