Methods The larvae dipping method was used to test the resistance to pyrethroid. 方法採用幼蟲浸漬法,測定其對擬除蟲菊酯類殺蟲劑的抗性倍數。
The effect of viscosity and dipping time on membrane, and that of calcining temperature and time on the structural properties of alumina membrane are also discussed. 還研究了膜厚與浸漬時間和粘度等的關係以及對比不同焙燒溫度和時間對氧化鋁膜的結構影響。
