叙述了浇铸温度高，保护渣润滑膜不均匀，铸坯拉速不稳定，二冷水不均匀，中间包水口不对中，合金钢铸坯冷却和再加热速度过快及钢中五害元素超标和结晶器铜管偏移等致使圆铸坯表面形成的 11种裂纹的特征及其预防措施。

The study indicated that the change of the strain of tangential bamboo appears mainly parabolic curve form, and the strain increase gradually from outside face to inside face in the thickness direction of bamboo wall in process of heating.

对四年生毛竹的弦向和径向热应变特性进行了检测和研究，研究表明在加热过程中弦向竹材的应变大体呈抛物线状变化，在竹壁厚度方向由竹青至竹黄应变呈逐渐增加趋势。

The results point out that the values of kinetic parameters are altered with the addition of Ti and C, which change the crystallization type from difficult nucleation and easy growth pattern to easy nucleation and difficult growth pattern, and this difficult nucleation and easy growth pattern may be the main reason why fine and even microstructure is gained in Ti and C doped alloys.The influences of Nd content, B content, partial substitution of Nd by Pr on the microstructure and magnetic properties have also been researched.

文章从动力学理论的观点揭示了合金显微结构与合金晶化动力学特性之间的关系，指出Ti和C添加改变了Nd9.4Fe79.6B11合金晶相析出时的动力学参量值，使合金晶化时晶相的析出方式由难形核易长大型加热管转变为易形核难长大型，这种易形核而难长大的晶化动力学特征，是Ti和C添加合金获得细小均匀的纳米晶结构的根本原因。

In the late 1980s,the $136 million Swedish company Kanthal,a sup- plier of heating wires,said that it would impose penalties whenever the $35billion GE changed specifications with- out warning.

在迟人中 1980 年代，那$一亿三千六百万瑞典的公司 Kanthal，一口-加热电线使用，说了它会强加处罚每当三十亿元的 GE 改变规格-出自警告。

This study reported the changes of the quality on the rape seed oil and rape salad oil by microwave heating.

就菜籽油及菜籽色拉油在微波下的质量变化进行了研究，结果表明：菜籽油及菜籽色拉油的羰基值、过氧化值、丙二醛、酸值随微波加热时间延长而升高，质量明显下降。

The technology is super-fast in nature—beyond infrared or e-beam methods—and it is selective. Heating of ceramics, glass and other materials can take place rapidly in a single site, significantly reducing a furnace's size.

采用这种技术，可在某一固定的位置对陶瓷，玻璃和其它材料进行快速加热，可大大降低了窑炉的尺寸。

Based on researching the shaft bearing replacer, this paper built the models of electromagnetic field and vortex density in bearing race snap being induction heating.

在研究轴承内环感应拆装的基础上，建立了感应加热过程中工件内电磁场和涡流分布的基本方程。

Numerical Simulation and Experimental Investigation on A Thermoacoustic Engine with Tapered Resonance Tube A symmetrical standing-wave thermoacoustic engine with tapered resonance tube has been numerically simulated with liner thermoacoustics. The simulation shows that using tapered resonance tube in thermoacoustic engine could decrease the velocity amplitude and lower the total acoustic power loss in the resonance tube. The experimental results indicate that the harmonic was suppressed effectively by using the tapered resonance tube, and the pressure ratio was improved.

采用锥形谐振管的热声发动机的数值模拟和实验研究利用线性热声理论，对一台采用锥形谐振管的驻波型热声发动机进行了数值模拟，发现采用锥形谐振管可有效降低工质气体的速度振幅，进而减小在谐振管中声功率的损失；与一台在相同频率下工作的采用等直径圆柱谐振管的驻波型热声发动机进行了实验对比，结果表明，在使用锥形管作为谐振管的热声发动机系统中，谐振管中的非线性效应得到了明显的抑制，热声发动机在基频模式下稳定运行，压比增大而加热温度降低。

Based on some basic hypothesis, the mathematic expressions of superheated steam heating area and heating radius are presented.

在一定假设的基础上，理论推导出了过热蒸汽带面积、加热带半径等的数学表达式。

This paper focuses on the optimal pitch arrangement in double-side heating once-through steam generator with helix tube inside.
