Samples of the equilibrium solid phase in Rb_2SO_4-PEG4000-H_2O system at 25 ℃ analyzed by TGA showed that they consisted of anhydrous salt. Six zones were observed in the complete phase diagram. They are L, L+L, L+S, 2L+S and L+2S, respectively. The binodal curves were given using a four-parameter equation y = a + bx~(0.5)+cx+dx~2. The tie lines were correlated by the Othmer-Tobias and Bancroft equations.

同时我们用热重分析仪对Rb_2SO_4—PEG 4000—H_2O三元体系在25℃时的平衡固相进行分析，发现在实验研究的温度范围内，体系的平衡固相均为无水盐，且在体系的完整相图中，观察到六个相区，分别为L，L+L，L+S，2L+S和L+2S相区，即非饱和的单液相区，非饱和的双液相区，饱和的单液相区，饱和的双液相区和两种固相(Rb_2SO_4，PEG 4000)存在的饱和单液相区。

研究了取代基性质对不同异构体和不同热解步骤的影响，发现四唑衍生物与相应的叠氮化合物之间存在平衡，吸电子取代基有利于平衡向生成叠氮化合物方向移动，取代基通过场效应和共轭效应影响5-取代-1H四唑的开环反应。

The simulation results showed a superheating about 193K in the Ag nanowires which is coated by Ni.

结果表明：自由Ag纳米线的熔点比大块Ag的平衡熔点低，而被高熔点的Ni包覆的Ag纳米线的熔点比Ag的平衡熔点高，即有过热存在。

The thermal stabilities of dithioesters, trithiocarbonates and xanthates were also compared,indicating that trithiocarbonates and xanthates are more stabile than dithioesters,while the chain transfer abilities of the latter are usually better than that of the former.So how to balance the chain transfer ability and the thermal stability of RAFT agents is a big challenge.

另外我们比较了双硫酯、三硫酯和磺原酸酯的热稳定性，发现后两者的热稳定性要远远好于前者，但前者的链转移能力一般要大于后两者，所以如何平衡链转移剂的链转移能力和其热稳定性之间的矛盾仍然是个很大的挑战。

In the model the collector is regard as a system, the outlet temperature is the system output, the other variables: the inlet temperature, the ambient temperature and the solar irradiance on aperture plane per unit area are the system inputs.

The problems of the heat transfer equation of cloud drop growth were analyzed from chemical potential and principle of phase equilibrium of multi-component system. It was pointed out that Clapeyron equation was the result gained under the condition of rigid phase equilibrium. It only shows the linear relation between steam press and temperature at saturation state, and does not show that there is any thermodynamic process which can meet this equation.

基于多元体系化学势和相平衡原理，分析了云滴长大热传导方程存在的问题，指出克拉伯龙方程是严格相平衡条件下推导出的结果，仅表示饱和状态下蒸汽压与温度之间的线性关系，并不表示存在满足克拉伯龙方程的热力学过程。
