The testing was done on the working conditions such as the sample resolution, element wave-length, air-carrier flow, auxiliary air flow, observed altitude, etc.
对样品的溶解、元素波长、载气流量、辅助气流、观察高度等工作条件进行试验，选定了最佳测定条件。
Among populations, mean body length and age at higher altitude were significantly larger than those at lower altitude.
在种群间，高海拔种群平均体长和年龄明显大于低海拔的种群。
Through selecting appropriate curve length of the reflection surface, it can reduce the reflection clutter of the near ground and improve the detection ability of low altitude.
合理选择反射区曲线的长度，可减少近地物反射的杂波，提高低空目标的探测能力。
