中文摘要：

氧载体中活性氧气的含量是衡量氧载体实用性的一项重要指标。自行设计了一种改进的碘量法测定混合气体中氧气的装置，完成了混合气体中微量氧气的测定，将该方法用于固相合成氧合氧载体中活性氧的测定，取得很好的结果，为混合气体中氧气的测定提供了新思路。

英文摘要：

Active oxygen in oxygen carriers is an important index for its practicability, so it is necessary to make reliable and precise memeasurements for active oxygen. A new airtight device is designed for iodometric determination of minim oxygen in mixed gases. The device has been applied to determine the active oxygen in oxygen carriers with satisfactory results, and it has also given a new idea for oxygen determination in mixed goses.
