在钢筋混凝土烟囱裂缝加固工程中采用了无粘结钢绞线预应力环箍，对加固过程进行了现场测试，经预应力环箍加固后的烟囱筒壁中建立的环向压应力在环箍处最大，其值约- 1.0 MPa ，环向压应力衰减较快。

However in Hachijo population, nymphal development was the fastest under LD 12:12h, followed by LD 14:10h and the slowest under LD 16:8h. Nymphal growth is restrained when the nymphs are transferred from LD 16:8h to LD 12:12h at 60 and 120 days after hatching, rapid development is observed when nymphs were transferred in the opposite direction in Hachijo population.

八丈岛种群的若虫在短日条件下发育最快，其次是中间日长，长日条件下若虫发育最慢，孵化后60d或120d将若虫自LD 16：8h向LD 12：12h转移抑制若虫发育，反方向转移的若虫快速发育。

The main changes were the downward and backward rotation of the mandible, the retrusion of the lower incisors, the protrusion of the upper incisors.FR-Ⅲ also promotes the growth of maxilla and reaches the normal relationship of the anterior overjet and overbite.

结果：FR-Ⅲ能矫正上下颌基骨异常的矢状关系，主要变化是下颌骨向下、向后旋转，改变下颌骨生长的方向，同时使下颌切牙舌倾、上前牙唇倾，上颌骨向前生长。

The lower tab at the base of the skull pulls the upper tab backwards and down towards the neck, which snugs up the hood and also affects the ride height of the semi-stiff brim.

脑壳底部有下拉片，作用是将上拉片向后和向下拉，以收紧风帽，使其紧贴头部，另外还会影响到半软硬帽沿的 ride height （估计是指帽沿的立起高度）。

Zen and Shin jump to catch them then one shoots an arrow while the other sends out the thunder toward the devil king.

天行还没说完，木土二人就痛哼了一声，向后飞摔而出，战心两人纵身接住了他们，然后一人射出圣箭，一人使出雷光，向天魔打去，可是圣箭一碰到天魔就消失了，雷光也像帮天魔搔痒般，天行著急的回身望去，只见一道白光从童博眉心激射而出，之后童博整个人都被白光包围，这团光瞬间变成光柱冲向天空，连已成形的天魔都被其强烈正气逼退了一步

After crushed by hammer crusher, the big materials become small sizes ones and they are sent to storage bin by elevator. The electromagnetic vibrating feeder will send them to the middle of first dial evenly, the materials will be driven to the edge of dial by centrifugal force, and fall down into the ring and crushed and grinded by roller, then the materials will fall down into the second and third ring, and crushed and grinded. The high pressure centrifugal blower will inhale air from the outside and blow the materials which are grinded in the third ring to powder classifier.

大块物料经锤式破碎机破碎成小颗粒后由提升机送入储料仓，电磁振动给料机将物料均匀的送到上转盘的中部，物料在离心力的作用下散向圆周边，并落入磨环的滚道内被环辊冲压、滚碾、研磨而粉碎，物料经第一层粉碎后落入第二层及第三层，高压离心风机的抽吸作用将外部空气吸入机内，并经过第三层粉碎后的粗粉带入选粉机内。
