张开

Based on the fictitious crack model and critical crack tip opening displacement CTODc, the precritical crack propagation length △ac of concrete was determined by means of three point bending beams. According to the calculation value of △ac, the effective fracture toughness KunIc of concrete was evaluated.

本文采用虚拟裂缝模型，将临界裂缝尖端张开位移CTODc作为控制参数，利用三点弯曲梁试件通过迭代求得了混凝土裂缝亚临界扩展量的临界值△ac，据此求得了混凝土起裂断裂韧度KiniIc、等效断裂韧度KunIc值。

It is found that the wing crack extend along a curved path and gradually approximate to the line which passes the middle point of the main crack and is parallel to the direction of maximum principal stress.

采用数值和试验的方法对翼型裂纹的扩展路径进行分析，发现单轴下张开型裂纹的翼型裂纹的扩展路径逼近于过原主裂纹中心点、平行于最大主应力的一条直线。

He saw her from behind, noted her swelling hips, her outstretched arms, while down on the floor, on the same level as her feet, the prompter's head--an old man's head with a humble, honest face--stood on the edge of the stage, looking as though it had been severed from the body.

Following the above instructions the opening of the parachute is perfectly possible from your normal flying position; the proof of this may be found in the parachute's proof sheet.

若您遵循上述指示，从您的正常飞行位置来张开伞是完全可能的；在进行伞的校样时候就有这种情形的发生。

When a pterosaur walked or remained stationary, the fourth finger, and with it the wing, could only turn upward in an extended inverted V-shape along each side of the animal's body.

"It was a stone-eun, there is a rock, Shi-eun like Tau, pyroxenite like cattle open mouth."

"那是一条石垠，中有一石岩，石垠像个牛头，石岩就像张开的牛嘴"。

After that the fractures in the right dam foundation slope were stretched at the beginning of the Quaternary Period because in the period Yakouhoushan mountain quaquaversal dome was blowups quickly. At the same time, the valley trenching of Lancang River reach to 800-1000 meter in altitude at the right bank in Nuozadu dam site. This two reason accelerated the groundwater infiltration in the right bank slope. So, the weathering agency could have invaded deeply in the right bank slope.

导致右岸岩体复杂化的成因是，右岸岩体在早期遭受了多期构造作用和岩体蚀变的基础上，第四纪早期丫口后山穹隆的快速隆起与当时河谷下切至800m～1000m高程这一特殊因素组合引起了右岸岩体沿原有的断裂张开，使地下水等风化营力能够到达坡体较深部位，经过长期的风化卸荷作用，形成了右岸复杂岩体。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
