  1. The results showed that its yield was inversely proportional to the concentration of - amylase and reaction time when the maize starch was hydrolyzed by - amylase ; the granular maize starch was converted into hollow - porous starch by ct - amylase, furthermore it was cracked to the fragments, it was discovered that there were laminated growth ring structure inside starch granular shown on such cracked granular fragments ; the crystallinity of maize starch granule can not he increased by the enzyme hydrolysis ; the thermodynamic stability of the product was reduced when the hydrolysis time was long

    檢測結果表明， -澱粉酶催化水解玉米澱粉時，其收率與酶的濃度和反應時間成反比；顆粒狀玉米澱粉發生酶催化水解時， -澱粉酶首先使澱粉形成多孔狀結構，並進一步使顆粒破裂，斷裂的顆粒碎片上顯示出澱粉顆粒內部具有層狀的生長環結構；酶催化水解不能提高玉米澱粉顆粒的結晶度；酶解時間較長時，產品的熱穩定性降低。
  2. 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。
