Confucius held that expediency means adjusting to changing circumstances, not necessarily going along with or against anything, having a sense of propriety about times and measures, and doing things in their proper time and manner. However, expediency does not mean doing whatever one likes without any principle; instead, it means taking benevolence and righteousness as criteria and acting accordingly. In Confucius＇s opinion, one should cultivate benevolence internally and act with righteousness externally, weigh importance and unimportance, measure advantages and disadvantages, and not ＂set the mind either for anything, or against anything,＂ pursuing ＂what the heart desires, without transgressing what is right.＂ In this way, he would keep to benevolence without deviating from it, act expediently without despising any principles, and attain a dialectical unification of expediency and principles.

In the present work, a novel α-aminophosphonate extractant（Cextrant 230） was synthesized for the extraction and recovery of cerium and thorium from sulphate medium. The introduction of amine group into the phosphate molecule would enhance the extraction of Ce（Ⅳ） and Th（Ⅳ）. The effects of extractant concentration, H2SO4 concentration and temperature on the metal extraction were investigated in detail. It was found that the extraction of Ce（Ⅳ）, Th（Ⅳ） and REs（La, Gd, Yb） in sulphate medium decreased in the following order： Ce（Ⅳ）〉Th（Ⅳ）〉REs（Ⅲ）. A solvent extraction process to extract and recover cerium and thorium from bastnasite leaching was proposed, in which the purities of cerium and thorium products reached 99.9% and 99% with yield of 92% and 98%, respectively.

张载认为,性可以从体、用两方面来理解。体之性是太虚之气所具有的“虚而神”的本性,是万物统一的根源、变化的动力,表现为神妙不测的变化性能;用之性是太虚之气所具有的大化流行之妙用,表现为天道流行过程。人之性是体之性、用之性在人伦社会中的呈现,可区分为天地之性和气质之性,天地之性是纯粹至善的,气质之性是恶的来源。人性修养的目的就是要根除气质之恶,复归纯粹至善的天地之性。要回归天地之性,使天地之性统率气质之性,既要“继善成性”,又要“变化气质”。
