Because the fish drying Shrinkage small Shrinkage crack surfaces, more in Water, so the bibulous rate of early (see figure 4) soon, absorbing ability, 1.2 m in bibulous rate (Water absorption Measurement can reach 1 36), In the early EHD water are slower, bibulous rate in 30 m in later, when the water absorption speed enough time to also can achieve higher bibulous rate and natural drying EHD with dry bibulous rate basic same, in addition, natural drying and EHD dry fish good water resistance, 120 m in water can still keep complete shape after drying fish, but by 120 m in pieces after absorbing began.

由于热风干燥鱼的收缩率较小、表面有较多缝隙，所以在吸水初期的吸水速度很快(见图4)，吸水能力很强， 120 m in 吸水率可达到1。 36； EHD在吸水初期的吸水速度均较慢，在30 m in以后吸水速度加快，当吸水时间足够时也能达到较高的吸水率，自然干燥与EHD干燥的吸水率基本相同，另外，自然干燥和EHD干燥鱼的耐水性好， 120 m in 吸水后仍能保持完整形状，而热风干燥鱼经120 m in 吸水后即开始溃散。

The relationship between the ratio of Ca to Si with shrinkage value was needed to be studied further.The strength of M-AAS was comparatively high, but the flexural strength was regressed in the long term. The compressive and flexural strengthes of 3 days were able to surpass 8MPa and 78MPa, respectively, and compressive strength of 90 days were all around 100MPa, but compared to flexural strength of 28 days, the flexural strength of 90 days was regressed by 19.0%. The high strength property of M-AAS associated with its hydration products and Interfacial Transition Zoo. The main hydration products of M-AAS were microcline and CSH, no calcium hydroxide was found. The coexistence of microcline and CSH worked as micro-aggregate by each other, and no weak ITZ, both resulted in its high strength. The regression of its strength was related to its high shrinkage property, because the crazing caused by shrinkage would decrease the strength, especially the flexural strength.

M-AAS强度较高，但长期抗折强度倒缩。3天抗折和抗压强度分别可超过8MPa和78MPa，90天抗压强度在100MPa左右，但90天抗折强度比28天抗折强度相比低19.0％。M-AAS的高强特性与其水化产物和界面过渡区有关，M-AAS的水化产物主要为微斜长石和CSH凝胶，没有氢氧化钙，微斜长石与CSH凝胶相互填充和配合共同起到强度的作用，M-AAS砂浆中几乎没有发现界面过渡薄弱区。M-AAS的强度倒缩现象与其收缩值较大有关，收缩会引起M-AAS硬化体内部出现微裂缝，使强度下降。

Harmonic frequencies and infrared spectra intensity for these clusters are given in order to aid in the characterization of the ground states. The results show that Si2CmN(m=2-10) clusters form linear structure, which are doublet states. The Si atoms favor to bond at ends of C and N linear chain. The ground state energies of clusters are nearly in proportion to increased m. The stability of Si2CmN(m=2-10) clusters with even m are greater than that with odd m.
