By the use of a precision automatic adiabatic calorimeter we have measured the heat capacities for water/silica adsorption system with various adsorbed amoun- ts over the temperature range from 200-320K.The results obtained show that when the amount of adsorbed water makes the surface coverage (θ)larger than 1,the peak for phase transition of adsorbed water will appear on the C_p-T curves.This means that aggregate of water molecules adsorbed on the surface of silica has for- med.On the other hand when θ<1,no phase transition is observed as the tempe- rature of the system rise and then the C_p-T curves are smooth.These phemomena are in coincidence with those in the H_2O/γ-Al_2O_3 adsorption system.Since the ad- sorption force for water molecules on silica surface is weaker than that on the γ-Al_2O_3,the peak profiles for water/silica is sharper than that for H_2O/γ-Al_2O_3 even if the two adsorption systems have the same amount of adsorbed water.The rise in the peak temperature with increase of amount of adsorbed water in the wa- ter/silica adsorption system is faster than that in the H_2O/γ-Al_2O_3.The fact men- tioned above shows that the two dimension water adsorbed on the surface of sili- ca could become bulk water easier as compared with the water adsorbed on the γ- Al_2O_3.Besides,the heat capacities for silica without any adsorbed water over the temperature range from 200K to 300 K have been obtained by extrapolating the C_p-T curves with.various adsorbed amounts at the same temperatures.

我们用精密自动绝热量热计测定了几种不同吸附水含量的水/硅胶吸附体系在200~320K 温度范围内的热容.结果表明,当吸附水含量使表面复盖度(θ)大于1时,在相应的 C_p~T 曲线上会出现吸附水的相变峰.这说明吸附在硅胶表面上的水分子已经形成了聚集态;而当θ<1时,由于尚未形成聚集态水,故没有相变过程出现,其 C_p~T曲线呈光滑状.这些现象与 H_2 O/γ-Al_2 O_3 吸附体系是一致的.又由于硅胶表面对水分子的吸附力较γ-Al_2 O_3 的要小,故在同样的吸附量的 C_p~T 曲线上,水/硅胶的峰要比 H_2 O/γ-Al_2 O_3 的尖锐,且蜂温增高的速度要快.这些都表明,吸附在硅胶表面上的二维表相水会随吸附量的增加而以较快的趋势接近于体相水.此外,由不同含水量的 C_p~T 曲线外推,求出了不含吸附水的硅胶在200~300K 范围内的热容.

By using an automatic adiabatic calorimeter the heat capacity measurements in the temperature range of 220-320K for H_2O/NaY zeolite adsorption system with various amounts of adsorbed water have been carried out. The results obtained from C_p-T measurements show that no peak for solid-liquid phase transition of adsorbed water occurs on their C_p-T curves.

By using an automatic adiabatic calorimeter the heat capacity measurements in the temperature range of 220-320K for H_2O/NaY zeolite adsorption system with various amounts of adsorbed water have been carried out. The results obtained from C_p-T measurements show that no peak for solid-liquid phase transition of adsorbed water occurs on their C_p-T curves. That means no aggregate state of water would be formed on the surface under this condition. Therefore, no solid-liquid phase transition would take place. Besides, the heat capacity measurements for H_2O/NaY zeolite systems have been done. The samples used in this series of C_p measurements had been prepared by mixing mechanically the saturated H_2O/NaY adsorption system with certain amount of water. There are clear peaks on their C_p-T curves. If the water mixed in the saturated adsorption system has been evacuated at once, the peak for phase transition on C_p-T curves will disappear. These water molecules should add on the external surface of the NaY particles. Owing to the interaction of water molecules and surface of zeolite, the heat, temperature and entropy of fusion for these water are lower than those of bulk water. All the facts mentioned above mean that the water adsorbed on solid surface are different from normal bulk water.

用精密自动绝热量热计测定了在220—320K范围内,不同含水量的H_2O/NaY吸附体系的热容.结果表明,在这些吸附体系的C_p-T曲线上均没有水的固-液相变峰.这说明即使在饱和吸附的情况下,水分子仍以单分子层的形态存在于NaY表面上,它们没有形成聚集态.此外,还测定了往饱和吸附的H_2O/NaY中再加入不同量水后所组成的H_2O/NaY体系的热容.在这些C_p-T曲线上都出现了明显的相变峰.所加之水一旦脱出,则相变峰又消失.这些水存在于分子筛颗粒之间,只与外表面接触.但仍受分子筛表面的影响.所以它们的熔化热、熔化温度均比正常水的要低.

There have been several hypothses proposed for the origin of massive ground ice oc-curing in unconsolidated sediments of Quaternary. Some of the hypothese are reviewed in this paper. As to the origin of massive ground ice at depth within bedrock, the possibilities that the ice can be of buried glacier ice, segregation ice, and segregation-intrusion ice can be discounted. Another possibility is that the ice formed by the freezing of bulk water in an existing aquifer, i.e., a cavity infilled by groundwater...

There have been several hypothses proposed for the origin of massive ground ice oc-curing in unconsolidated sediments of Quaternary. Some of the hypothese are reviewed in this paper. As to the origin of massive ground ice at depth within bedrock, the possibilities that the ice can be of buried glacier ice, segregation ice, and segregation-intrusion ice can be discounted. Another possibility is that the ice formed by the freezing of bulk water in an existing aquifer, i.e., a cavity infilled by groundwater under artesian pressure as permafrost aggraded. However, it is hard to explain why such a cavity existed in the first place, and why the overlying strata did not collapse before the ice formed because the rock were fractured by faulting. It follows that a more likely possibility is that the massive ground ice formed by the in-situ freezing of groundwater intruded under pressure(i.e.intrusive ice).

对松散沉积物中的大块地下冰已有多种成因假设,而基岩中的大块冰可以排除分凝,分凝—侵入及埋藏等成因机制。岩芯的破碎程度及水文地质条件分析表明,霍拉河盆地发育于泥岩及煤层之间的大块地下冰属侵入冰,即承压地下水侵入岩层裂隙后冻结而成。在冻结中,冰体的体胀力及地下水的侵入力使上覆岩层压密或有些抬升,由此为大块冰的生长创造空间条件。同时真空—渗透机制也不应忽视。
