1) creeping of fissure
裂纹蠕动
2) creep crack
蠕变裂纹
1.
Studies were made on the nucleation of creep cavities and propagation of creep cracks in steel 20Cr11MoVNbNB at 550-650℃.
研究了20Cr11MoVNbNB马氏体热强钢在550—65℃范围内蠕变孔洞的形成及蠕变裂纹的发展发现蠕变孔洞主要在原奥氏体晶界和原板条马氏体边界上的淬火未溶大颗粒Nb（C，N）及M23C6碳化物处形成，孔洞在原奥氏体晶界形成倾向不占优势：蠕变裂纹沿垂直应力方向横穿原奥氏体晶界及原板条马氏体边界向晶内扩展，最终导致穿晶断裂。
2.
Because the pendent reheater tubes were subjected to thermal shock of steam blown by a sootblower during service,the thermal fatigue crack on outside surface was caused,and the creep crack adjacent to inner surface subsequently appeared.
管材在运行中遭受吹灰蒸汽的热冲击,外壁因此出现热疲劳裂纹,随后内壁金属衍生出蠕变裂纹。
3) creep brittle crack
蠕脆性裂纹
1.
In order to describe steady state growing creep brittle crack tip singular field,the dimensionless parameter R ec is derived.
由７１８合金的蠕脆性裂纹扩展试验结果得到准则关联式，从而得到蠕脆性裂纹稳态扩展的速率公式。
4) creep crack growth rate (CCGR)
蠕变裂纹扩展率
1.
A theroretical equation for the calculation of creep crack growth rate (CCGR) has also been derived.
根据局部损伤理论和相似原理 ,给出了蠕变裂纹启裂前的孕育上下限时间并推导了蠕变裂纹扩展率方程。
5) creep crack growth
蠕变裂纹扩展
1.
How to charcterize the creep crack growth with appropriate fracture mechanics parameters is rather challenging to the structural integrity assessment in the presence of weld interface.
为此建议对ASTME145 7推荐的C 计算式进行修正 ,以正确演绎焊接试样的蠕变裂纹扩展行为。
6) torsional creeping crack
扭转蠕变裂纹

肠蠕动和肠蠕动波
peristalsis and peristaltic wave
患者仰卧，显露出全腹，检查者观察其腹部外形，可发现特殊的局限性腹壁膨隆或肿物。其为位置不定的鼓胀现象，大小不一，长短不等。有的为局部鼓包，有的具肠管外形。触之表面光滑、质软、囊感。叩诊多呈鼓音，此即肠形。肠形上有时可见不规则的波动，有的间或出现，有的此起彼伏，即肠蠕动波。
