除鯁器，食管探子纖細而可彎曲的長圓棒，其一端有一小片海綿或毛撮，用來去除喉部或食管的外來異物或給喉部或食道上藥 -
On the basis of study on structure and mass transfer, ideal model of membrane structure was built up, in which skin layer should be as thin as possible ensure resisting water to pass though membrane ; finger pore should be as long as possible in the membrane ; proper pore size ; loose sponge tissue
首先對利用相轉化法制備的微孔膜形態結構進行研究，確定傳導阻力較小的理想結構模型，緻密層在能阻止微孔被浸潤的情況下盡可能薄；指狀孔在膜厚方向所佔比例盡可能大；孔徑大小適宜；海綿狀組織結構疏鬆。 -
Even though hms can be prepared much more easily than mcm - 41 and has certain advantages such as thicker framework walls, superior thermals stability, and a smaller crystalline size. hms have more recently been shown to possess wormhole - like or sponge - like framework structure rather than the long - range hexagonal framework structures characteristics of electrostatically assembled mcm - 41. the wormhole channel motif is a potentially important structure feature for favorable catalytic reactivity, in part, because channel branching within the framework can facilitate access to reactive sites on the framework walls. furthermore the wormhole channel motif suggest that they could serves as ideal hosts for rational nanomanufacturing
1995年， tanev和pinnavaia報道，用中性模板劑合成了一類新的六方介孔固體（ hms ） ，它具有不同於用靜電路徑合成的mcm - 41介孔固體的物理和化學性能，如制備工藝簡單、孔壁厚、熱穩定性好和晶粒尺寸小等。 hms還具有蜂巢或海綿狀結構特徵，而不象mcm - 41那樣是長程有序的六方結構。這種蜂巢或海綿狀結構特徵除有利於催化反應，反應物易於接近孔壁上的反應位外。
