湿敏电阻

Cu doped ZnO thin film can detect 100 ppb propyl alcohol vapor, while Mn doped ZnO thin film exhibits high sensitivity to NH3 and H2O vapor.Furthermore, the photoluminescence properties of ZnO and Tb doped ZnO thin films, heat-treated in different atmospheres, were carried out.

薄膜气敏性研究表明，Ti的掺杂使ZnO膜电阻降低；Cu的掺杂使薄膜对正丙醇的选择性增高，可检测痕量(100 ppb)的正丙醇：Mn掺杂薄膜显示出很好的氨敏和湿敏性能。

The best linearity of the curve of impedance versus relative humidity appears at the frequency of 100 Hz.

制备了电阻式纳米钛酸钡湿敏元件，测试了元件的阻抗、电容，以及介电损耗特性。

In the second part, the current-voltage characteristics of the sensors were measured, their charge ionic mobilities were measured with polar inversion method and their ionic numbers were computed. It has found that ionization effect of some binding ions against a critical humidity took place in switchable humidity-sensitive materials, the effect is that some binding ions in materials turn into free ions when a given ambient humidity is reached called a critical humidity, avalanching conduct electricity occurs in materials.

在第二部分中，测试了高分子电阻型湿敏元件和开关型湿敏元件的伏—安特性，并用极性反转法测试了其导电离子的迁移率以及计算了相关的导电离子数目，发现了开关型湿敏元件的束缚离子的最小湿度电离效应：当环境湿度达到或者大于一特定湿度时，这一特定湿度称之为最小湿度，材料中某些束缚离子才电离成自由的导电离子，形成雪崩式导电。

Relative humidity was deduced on the basis of Arrhenius relation and a lot of experimental data, the experimental results were in good agreement with the formula.

在第三部分中，测试了高分子电阻型湿敏元件在不同湿度的阻抗值，通过计算机模拟和拟合，导出了与实验数据更相符合的新型经验公式。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
