安装时应确保其发热部在炉腔内，没有超出炉壁或者难熔插栓的部分。

So we have different kind of heating elements, low-temperature , high-temperature , washable heating film which is suitable for

所以我们有不同的加热元件、低温、高温、水洗取暖适合电影

We made use of Wheatstone bridge to control ratio of heating power between the samples, Thus , it enable to control and measure the differential heating power accurately. Consequently, it improves sensitivity of the system.

采用惠斯通电桥来控制两个样品间加热功率的比例，这样能够更准确控制和测量两个样品加热的功率差异，从而提高了测量的灵敏度。

The samples of 600℃ group didn't crystallize, but the color became darker and yellower as the peolongation of the heating time; the samples of 650℃ and 700℃ groups crystallized in different degrees, the translucency and Chroma decreased as the prolongation of the heating time, but the Value increased.

600℃组各样本均未晶化，随着保温时间的延长，其颜色逐渐加深，偏黄，650℃及700℃组各样本均发生不同程度的晶化，随晶化温度的升高及保温时间的延长，样本的透明度逐渐降低，亮度逐渐升高，色调变浅且饱和度逐渐降低

Because the liquid nitriding the liquid and the work piece direct conduction heating, reduced the work piece heating-up time, raised the azotize speed.

液体氮化由于液体与工件直接传导加热，缩短了工件加热时间，提高了渗氮速度。

TEM shows that drying by direct heating might result in hard aggregation of the tourmaline powder, while hard aggregation might be avoided by azeotropic distillation. Raman spectroscopy reveals that there are O_H and C_H on the surfaces of the tourmaline powder obtained by azeotropic distillation, which indicates that butoxy is chemically adsorbed on the surfaces of tourmaline particles, but not adsorbed on those formed by direct drying. X_ray powder diffraction shows that the intensity of diffraction peaks decreases after grinding. There is no damage to the tourmaline crystal lattice in the process of direct heating, azeotropic distillation, or ultrafine grinding.

透射电镜分析结果表明，直接加热脱去水或正丁醇会使电气石超细颗粒发生硬团聚，而共沸蒸馏法则可有效防止硬团聚的产生；拉曼光谱结果表明，共沸蒸馏法制备的电气石粉末表面存在O—H和C—H键，说明正丁醇在颗粒表面为化学吸附，而直接干燥法得到的电气石粉末表面则没有；X射线粉晶衍射结果表明，研磨过程降低了粉末衍射峰的强度，但直接加热干燥和共沸蒸馏干燥均未破坏电气石的晶格结构。

This paper deals with how to use optimum method to make economical comparisons of the following heating systems: the hot water boiler, heat exchanger system, steam jet system and shower calorifier system, which are widely used in industrial boiler house.On condition that the nature of the untreated waters, rate of condensation recovery, fuel costs, heating days, and temperature drop of flow and return water are different, a lot of analysis and comparisons have been made in this paper and optimal designs for...

本文论述了对工业企业锅炉房内几种常用热水制备系统(热水锅炉、换热器系统、蒸汽喷射系统和喷淋加热系统)如何应用最优化方法进行经济比较的问题；并且对其在不同给水水质、燃料价格、采暖天数、凝结水回收率以及不同的送、回水温差等条件下，作了大量分析和比较，从而为计算者推荐出不同条件下的最优方案。

Meanwhile, the optimum operation conditions obtained by orthogonal experiment are as follows: microwave power is 585 W, irradiation time is 30min, the amounts of catalyst is 1.5% of feed stock, mole ratio of alcohol to acid is 1.5:1, the yield of isoamyl chloroacetate is 93.2% Comparing with conventional heating method, the heating time under microwave irradiation is less than 1/14 of the former.

最佳工艺条件为：微波功率585W，加热时间为25min，催化剂用量为2.0%，醇酸比为1.5：1，此条件下氯乙酸异戊酯的产率为93.2%。对比实验结果表明，微波辐射加热法合成氯乙酸异戊酯的反应速度至少是常规加热法的14倍。
