表征

The results show that single structure parameters (width and depth of flow path/passage, and height, and angle of dentations) are local and difficult to represent the anti-clogging ability of emitters. Characteristic structure parameters(minimum size of cross section, hydraulic radius and dentitions spacing) can represent the anti-clogging ability of emitters in a sense. There are anti-clogging critical values under the test. Rated flow Qr and the ratio of diameter of labyrinth passage to diameter of particle η are well cor related to the anti-clogging ability and have anti-clogging critical values too.

结果表明：用单一结构参数(流道宽度 W 、流道深度 D 、齿高度 h 和齿角度θ)表征其抗堵塞性能存在局限性；结构特征参数断面最小尺寸 min(D，W、水力半径 R 和齿间距 l 能较好反映滴头流道横、纵断面的结构特征，在不同程度上表征了流道的抗堵塞性能，且在试验条件下各自均存在抗堵塞临界值；滴头额定流量 Qr 和迷宫滴头径粒比η与抗堵塞性能相关性较好，且存在抗堵塞临界值。

The title of the exhibition is "Infiltration: Idylls and Visions", it aims at regarding "ink" as a kind of cultural image and at providing a different creative and experimental text through setting ink work into relation to the present artistic experimentation to explore finally the potential and uncertainty of the contemporary deduction of ink painting's cultural connotations and references.
