患者，女性，52岁。间歌性上腹部疼痛10余年，每年秋冬季好发，劳累后明显。近1个月感上腹部饱胀不适，疼痛于餐后加重，有反复大量呕吐，呕吐后疼痛缓解，入院治疗。为明确病因，下列选项中，诊断溃疡的重要依据是（）
Today, a whopping 20% of global energy demand goes to producing heat used in industry, and most of that heat is generated by burning fossil fuels. In an effort to clean up industry, a growing number of companies are working to supply that heat with a technology called thermal batteries. ...
the user. however, you can indirectly affect the power consumption and heat dissipation of a component by adjusting certain settings, such as undervolting or underclocking, which can lower the actual power consumed and heat generated. how can i ensure effective cooling for components with high ...

Electricity generated by burning fossil fuels such as coal, oil and natural gas, emits carbon dioxide, nitrogen oxides and sulfur oxides -- gases scientists believe contribute to climate change. Solar thermal (heat) energy is a carbon-free, renewable alternative to the power we generate with ...
A heat sink is a component used in electronic devices to dissipate heat and prevent overheating. It is typically made of a thermally conductive material, such as aluminum or copper, and is designed to absorb and disperse heat generated by electronic components. ...

The coupling has two sources: the dependency between the electric conductivity and the temperature, and the relationship between the generated internal heat and the electric current. However, in our analysis the electric conductivity is considered independent of the temperature. Moreover, the thermal ...
