wet-stream sampling

RESULTS: ① When measuring skin area over tissue expander or surface area of the shot by wet-cloth sampling method, coefficients of variation were all less than 2%.

结果：①采用湿布取样法重复测量的扩张器表面皮肤面积和铅球表面积，其变异系数均小于2%。

In additional, the calculation formula of the wet sampler was deduced. Secondly, adopting the principle of wet sampling method, such as negative pressure suction, mist turbulent impinging and liquid sealed face to design a novel nano-TiO2 aerosol wet sampler.

此外，还推导出采样器采集效率的串联法计算公式。其次，采用射流负压吸气、湍流喷雾冲击、液封面捕获等湿法采样原理设计出一套新型纳米TiO2气溶胶湿法采样器。

Twelve sampling plots of wet-rice field were investigated of twelve households of Daka, Xishuangbanna, Yunnan.

通过随机抽样和农户推荐，对西双版纳大卡老寨12户农民的水田采用典型取样法设立48个1m2（1×1m）的样方进行调查并结合现场社会经济状况调查。
