Moreover, the electromagnetic flux density and meniscus height increase in the form of chequerboard with increasing of slit number. The numerical results can exactly illuminate some experimental phenomena, and enrich the theoretical foundation of soft-contact continuous casting technology. In practice, a softcontact mold with slit number of 16 or 24 is recommended, the suggested frequency is around 20kHz, and the slit width is about 1mm.

He forced himself to ignore her, trying to concentrate instead on the crenellated silhouette of the port facilities of Aberdeen, but he soon realized that his heart was beating to burst in his chest.

他强迫自己忽略她，企图把注意力放在阿伯丁港口那些有着钝锯齿形的设施的剪影上，但是他很快意识到心在剧烈地跳动，好象要从胸口蹦出来一样

This bore a tall piece of wood, adzed-flattened on its two faces with the sides indented or crenellated in regular squares; it had something of the air and presence of a totem-pole and it was topped by a skull.

这个艏柱上顶着一块高大的木头，木头的前后两面用手斧刨平了，左右侧面刻着很多锯齿状凹凸不平的正方形；这块木头有图腾柱的外观和气势，顶上还放着一个骷髅。

The country's extensive system of national parks includes some of the most photographed and best preserved landscapes on earth—like Yosemite Valley in California, the crenellated Teton Range in Wyoming, Old Faithful geyser in Yellowstone National Park or the white edifice of Mount Rainier in Washington state.

The flow field in the axisymmetric crenellated radial labyrinth seal is simulated by the present numerical scheme, which emphsizes on examining the influence of relative teeth engaging length τ/T on the sealing property. It is found that the sealing property is firstly improved with the increase of engaging length, and becomes worse as the τ/T further increase, thus an optimal τ/T is existed.
