The materials involved in the calorimetry are modeled here as a volume of water , a source of heat which is characterized by its equivalent water mass , and the container or calorimeter with its mass and specific heat 该材料在热都是仿照这里作为体积的水,热源,其特点是它的等效水质量,以及集装箱或量能,其质量和比热。
At first , we get the source of heat in high power laser diode and diode ' s characteristics depending on temperature basing on some basic physical concepts and analysis on the mechanism of heat in high power laser diode 在本文中,首先从基本的物理概念出发,对大功率激光器中热损耗机理进行分析,得到了大功率激光器阵列中的热源和大功率激光器的温度特性。
Because the only source of heat that could melt the entire moon would be a very rapid accumulation of small bodies , the presence of large quantities of anorthosite in the lunar crust supports the theory that the moon coalesced from the debris of a planetary collision 能熔化整个月球的唯一热源是小型天体的快速聚集,因此月球地壳内大量的斜长岩支持了月球是由行星际遗屑撞击合并而成的理论。
The afterheat , which is collected by recovery devices , in winter can be used as the low level thermal source of heat pump , and in summer can preheat feed water , thus equivalent an economizer . because energy flows in the system so reasonably that energy is used to the most , therefore , its energy conservation effect is significant , and the operating expenditure declines consequently . the sewage can be reused after due treatment , thua it has a certain social and ecological benefit , too 本研究中选用分离式热管装置提供洗浴用水,利用水源热泵装置,一机两用,进行空间供热和制冷,并通过余热回收器对系统内的余热进行回收,冬季可作为水源热泵的低位热源,夏季可对锅炉给水进行预热,起到“省煤器”的作用。这样实现系统内的能量合理流动,从而达到节能的目的,同时洗浴污水经适当的处理后可以回用,因而还具有一定的社会和生态效益。
Fanned by a constant updraught of ventilation between the kitchen and the chimneyflue , ignition was communicated from the faggots of precombustible fuel to polyhedral masses of bituminous coal , containing in compressed mineral form the foliated fossilised decidua of primeval forests which had in turn derived their vegetative existence from the sun , primal source of heat radiant , transmitted through omnipresent luminiferous diathermanous ether 自厨房至烟囱的孔道,不断地向上通风,灼热的火被它煽得从成束的易燃柴禾延烧到多面体烟煤堆上。这种煤炭含有原始森林的落叶堆积后凝缩而成的矿物状化石森林之发育生长靠的是热辐射性源-太阳,而热又是由那普遍存在传光并透热的能媒33传导的。
