This process can be carried out in an atomically economic way from the viewpoints of both material and energy utilization, which could significantly improve the efficiency of the process.

加氢和脱氢耦合法可将加氢反应的放热用于脱氢反应的供热，减小了过程的热效应，可有效避免反应器的局部过热或过冷；脱氢反应释放的氢可用于加氢反应，整个过程无氢消耗，具有能量和原子的经济性，显著地提高了整个过程的效率。

According to experts' advice, more than 90% of adults suffer from periodontal disease of different degrees, especially those often smoking tobacco and drinking coffee, they have dental plaques on their teeth, and their gums are apt to bleed; people with a peculiar smell in their mouth cavity had better do toothwash regularly; everyone should develop a habit of toothwash once every half year or once every year according to their different conditions of the teeth; in the week after the toothwash, they are advised to avoid eating too cold or too hot food.

专家提醒，90%以上的成年人都有不同程度的牙周病，特别是经常抽烟喝咖啡、牙齿上有牙菌斑、牙龈容易出血、有口腔异味的人最好能定期洗牙，每个人应根据自己牙齿的不同状况，养成每半年到一年洗牙一次的习惯，洗牙后的一周，应尽量避免吃过冷过热的食物。

Trombe wall has been invited forty years ago, and lots of researchers involved in studying its diurnal thermal performance in winter. Their terminal object was to improve Trombe wall's thermal performance and popularization by meliorating its structures and materials. But there are little studies about Trombe wall's overheating in summer and overcooling in winter night. In order to popularize the application of Trombe wall, especially use it in the city residential buildings, it must solve the two "over-" problems.

其中，特朗贝式集热蓄热墙作为一种传统的被动式集热部件发展已有40几年的历史，虽然国内外学者针对其冬季白天热性能进行了深入研究，对特朗贝墙体结构形式和使用材料做了很多改良，但特朗贝墙体冬季夜间过冷和夏季白天过热的问题一直没有得到很好的解决。
