This article analyses some basic conceptions that are comparatively vayue or even wrong wrong in the teaching of middle school chemistry, like the definition of chemical change, the influence of concentration on a chemical reaction , the structure of oxacid,and the acidity of sulfuric acid, the acidity of carbonic acid, and the conversion of allotropic substance.

分析了中学化学教学中的几个比较模糊甚至错误的基本概念，如化学变化、浓度对化学反应速度的影响、含氧酸的结构、硫酸的酸性、碳酸的酸性、热化学方程式的表示法、同素异形体间的转化等，并从大学化学角度加以澄清，以便使大一学生更准确地理解和掌握这些基本概念。

We choose the seeds of pinaceae and taxodeaceae as research material of tree classification.

由于种子是一个复杂化合物的有机体，我们期望发现各不同种子化合物之间在成份上和组成方式上的共性和差异性，从热化学的角度对木本植物进行热化学分类。

The pilot study shows that the ammonia dissociation/synthesis reaction is inherently free of any potential side reaction problems, and also offers phase separation of products. The carrier of heat store is liquid. and is very interesting for long-term storage as it can be carried out at room temperature with no energy losses, Its theoretics energy storage density reachs 66.5kJ/mol, which outclasses sensible or latent heat storage. In comparison to other thermochemical energy storage, ATCES needs lower temperature in endothermic reaction(only 650℃), but It can produce over 550℃ high temperature stream in exothermic synthesiser. Furthermore, the heat store/recovery can change with adapt to the heat source/load automatically, and offers coninuous(24 h) production of heat, These advantages will see a rapid increase in the adoption of large-scale concentrating solar thermal power generation.

初步研究表明：采用氨基储能体系，储/释过程无副反应，且储能介质能自然发生相分离；储热载体为流体，并可在室温下长期无热损储存，理论储能密度达66.5kJ/mol，远高于显热或相变蓄热；与其它热化学储能相比，吸热反应温度低，仅需650℃，而放热反应可产生500℃以上的高温，能量的储/释流量可随热源/负荷自适应变化，且可全天供热，更适合作为聚光式大规模太阳能热力发电中的能量储存系统。

Thermochemical Hole Burning memory uses the STM heating effect to induce a localized thermochemical decomposition of Charge Transfer Complexes, evolving the low-boiling point donor component and creating nanometer-sized holes on the crystal surface.
