Apron Protection for Concave Bank Along River Subgrade of Mountain Area

Pa/ Peof concave bank point bars averages 5.3, which is near that of half-matured point bar.

凹岸边摊的Pa／Pe值与半成熟边滩接近.平均为5.3；

Therefore, the scheme of four cages that are disposed on the side of concave bank is the last scheme according to the practical engineering problem.

因此，针对所要解决的工程实际问题，决定采用紧靠凹岸布置四道斜底槛的方式作为最终的消减急流冲击波方案。

The beam sizes reflected from the concave mirror and the plane mirror are 48 mm and 5.1 mm, respectively. The angle adjusting precision of the plane-concave resonator is 3.18 ′.

得到由凹面镜和平面镜反射回来的光斑直径分别为4.8mm和5.1mm，平凹腔的角度对准精度达到了3.18′。

Practical application showed that the improved crystallizers solved the problems such as concave big plane and flat side plane of the ingot successfully, and thereby the producing rate was enhanced effectively.

实践证明，对结晶器的改进，成功地解决了扁铸锭大面凹、小面分层的问题，提高了铸锭铣面成品率和热轧成品率。
