Furthermore, the problem of coupled piezothermoelastic response of a piezoelectric cylinder of crystal class 6mm is investigated. Analytical solutions for this problem are successfully obtained by using Bessel-Fourier series expansion and Laplace transform. These solutions are helpful for study of the influence of coupling on the distribution of stresses, displacements, electric potential and other quantities as well as the role of inertia term.

从2004年开始，北京已取缔了94000个煤火炉。高热效的电热供暖器，使得以前每年因燃烧约100，000吨的煤而产生的煤烟，在北京胡同的烟囱里消失。

Rotisserie cooking alternates high and low heat many times: as the meat turns on the spit, each area of the surface is briefly exposed to high browning heat, then given time for that dose of energy to dissipate, part of it into the meat but part back out into the cool air.

电热轮转烤肉器轮换用高、低火多次：肉在烤肉叉上旋转的时候，其表皮的每个区域都暴露在使其变焦脆的热度下，然后等这股热度消散，一部分热能进入肉里，一部分又回到周围温度相对低的空气里。

Only when the flow rate of steam is more than this point, can back pressure turbine be used.

从经济的角度而言，以蒸汽流量为判据，两种设备的应用有一个经济出力分界点，只有当蒸汽流量大于该分界点时，采用背压汽轮机才是有利的，且该经济分界点随着电力价格和电热比价的变化而变化。

A hypothetical drained cell model retrofitted from a 160kA Hall-Heroult cell was set up to calculate the current distribution in the cathode when the anode bottom and cathode top surfaces were declivous. Two half anode-cathode slice thermo-electrical models with the collector bars installed slopingly or horizontally were adopted to calculate the potential drop and electricity distribution of the cathode.

Besides, the influences of different kinds of cathode blocks on the thermo-electric distribution in the lining were studied. The results showed that, with the increase of the content of graphite or the graphitized degree in the cathode blocks, the thermal gradient and voltage drop in the cathode decreased greatly; the liquidus isotherms moved toward the end wall and side wall in the vertical direction, but moved little in the firebricks.

此外，通过研究阴极炭块种类对内衬中电热场的影响，发现随着炭块石墨含量的增加，炭块的温度梯度、炭块中的电压降以及电解槽槽底电压降显著降低，电解质凝固等温线往槽大面和小面方向偏移，但在耐火砖内位置变化不大。
