Hess law 双语例句
By applying Hess's law, the decomposition heat of coal can be easily obtained by means of thermodynamic data available and simple experiment for the measurement of quantity of heat.
根据现有的热力学数据、煤粉的成分以及煤粉发热值的理论计算公式或氧弹量热实验测定的数据，用新方法可确定出新的煤粉分解热数据。
Finally, the standard molar enthalpy of formation for the compound was determined to beΔf H mo＝－(56.76±2.13) kJ·mol－1, in accordance with Hess law.
最后，依据Hess定律计算出烟酸的标准摩尔生成焓为：Δf H mo＝－(56.76±2.13) kJ·mol－1。
Finally, the standard molar enthalpy of formation of anhydrous potassium nicotinate K(C6H4NO2) was determined to be ＝－(560.57±1.09) kJ·mol－1 in accordance with Hess law.
最后，依据Hess定律计算出烟酸钾的标准摩尔生成焓为＝－(560.57±1.09) kJ·mol－1。
In accordance with Hess law, a reasonable thermochemical cycle was designed, and standard molar enthalpies of dissolution for the reactants and products of the designed reaction in the selected solvent were measured by an isoperibol solution-reaction calorimeter, respectively. In addition, the enthalpy change of the reaction was calculated to be△H(superscript Θ subscript m)rH5r(1.787±0.514) kJmol^(-1) from data of above standard molar enthalpies of dissolution.
另外，依据Hess定律，通过设计合理的热化学循环，利用等温环境溶解一反应热量计分别测定所设计反应的反应物和产物在所选溶剂中的溶解焓，得到该反应的反应焓为△H=(1.787±0.514)kJmol^(-1)。
According to Hess's law, a new thermochemical cycle was designed. The dissolution enthalpies of reactant (△H1) and product (△H2) were performed by a RD496 microcalorimeter at 298.15K using aqueous solution of hydrochloric acid (4mol/L) as a calorimetric solvent. Ultraviolet spectrum, conductivity and refractive index were measured respectively. The results show as follows:△H1=(-47.180±0.084) kJ/mol, △H2=(-7.617±0.096) kJ/mol.
根据Hess定律，设计了一个新的热化学循环：以4mol/LHCl溶液为量热溶剂，用RD496微热量计於298.15K则定了反应物与产物在量热溶剂中的溶解焓分别为(-47.180±0.084)和(-7.617±0.096)kJ/mol，同时测定两种溶液的紫外光谱、折光率和电导率。
An equation that relates the average particle size of precipitates with various reaction conditions-surface tension of solid-liquid interface, solubility of precipitates, excessivity of reactants or pH under certain condition and temperature-was derived based on the Hess law and Kelvin equation; the relation between the particle size of precipitates and initial concentrations of reactants as well as the stirring power was also worked out in accordance with energy conservation law. Experimental results were in well agreement with the thermodynamic equation except the influence of temperature and stirring on the particle size. The kinetic analysis explained well the function of stirring and the influence of temperature on the particle size.
根据Hess定律、Kelvin公式导出了液相沉淀反应体系中沉淀物的平均粒度与固液界面张力、沉淀物的溶解度、反应物的过量度（在一定条件下可视为体系的pH值）、反应温度等因素的定量关系式，并从能量守恒角度推导了反应物的初始浓度、搅拌功率与沉淀粒度的关系；实验表明：固液界面张力、沉淀物的溶解度、反应物的过量度和反应物初始浓度与沉淀粒度的关系均与热力学分析相吻合，但热力学粒度公式不能明确解释反应温度和搅拌功率对沉淀粒度的影响。
Recently, Hess's Law in broad sense has been proposed clearly, but no theoretical treatment has been made.
最近文献中已经明确提出了广义Hess定律的概念，但未作理论处理。
Hess'Law states that for any chemical reaction, the energy change is path independent.
盖斯定律表明，对于任意化学反应，能量变化并非是路径依赖的。
