A simple estimation method for molar Gibbs free energy and enthalpy of formation for complex oxysalt minerals is proposed. Complex oxysalt minerals are divided into complex oxysalt minerals with water and complex oxysalt minerals without water. Complex oxysalt minerals without water can be considered as the composite of acidic oxides and alkaline oxides, so their molar Gibbs free energy or molar enthalpy of formation can be calculated by the summation of molar Gibbs free energy or molar enthalpy of formation of the acidic oxides and alkaline oxides which are combined into the complex compounds.

If it was resonating at a radio frequency of 2 MHz, then the energy released during one period of its oscillation would be 100,000,000,000,000,000 joules of energy, or roughly the amount of energy released by the explosion of 10 megatons of TNT.

如果这是共鸣的无线电频率的2兆赫，然后释放的能量在一个时期的振荡将是100，000，000，000，000，000焦耳的能量，或者金额大致能源公布了爆炸的10兆吨TNT炸药。

The results show that the discharge and cooling stages of sparkjet were simulated by computational method. The instance energy input can produce the condition of high pressure and temperature in the actuator, which induce the forming of synthetic jet. With the increment of the input energy, the velocity of the synthetic jet could be increased to the supersonic state. Under the periodic energy input, the distribution of the sparkjet velocity on the nozzle is non-sinusoidal. And the discharge velocity of jet is much larger than the suction velocity of the flow from environment.

计算结果表明：采用本文的计算方法可以模拟出火花型激励器喷射、吸入的工作阶段；电火花瞬间能量的输入产生了腔体内的高温、高压环境，从而诱发合成射流的形成；当激励能量增加，激励器产生的合成射流速度增加，可达到超声速状态；周期性激励下，火花型合成喷喷口处的轴向平均速度随时间不是正弦分布，且喷射过程的最大速度要远远大于吸收过程的最大速度。

Piccard said: On solar energy, you have to capture the energy with solar cells on the wings, store this energy in the batteries and at the same time, run the engine during the day.

" 皮卡尔说："在太阳能，你必须捕捉的能源与太阳能电池的翅膀，储存能量的电池，并在同一时间，运行引擎在一天。

Furthermore,in order to obtain the best energy saving,Sushi Jet has three independent heat chambers of temperature control ,each of which can be set whether to work or not in the production run according to the operational method of screen printing and identity of ink .Testing data shows that it only needs to open two sets of heat chambers when drying water- based binder under 120 ℃,and the average energy consumption costs is only 10 yuan / hour. In the plastisol ink drying process,the cost of the average energy consumption is less than 25 yuan / hour with opening three groups.

另外，Sushi Jet型燃气炉具备三组独立控温的烘区可根据印花工艺、油墨原料特性减少开启烘区，从而达到最佳节能效果，经检验数据表明在烘干水性普通胶浆时，仅需开启两组烘区。120℃下平均能耗成本，仅为10元/小时，热固油墨的烘干过程，在开启三组烘区，160℃下的平均能耗成本低于25元/小时。
