| 1. | The moon was in its last quarter, and was long beset with clouds, but after a while, shone out .
这下弦的弯月长久地被云层所包围，过了一会，才射出皓光。 |
| 2. | The moon is in its last quarter
月球现处於下弦 |
| 3. | Curved bottom chord
曲线形下弦杆 |
| 4. | Neap tides : tides of small range occur when the moon is at its first or last quarter
小潮：出现在每个月上弦或下弦时期，潮差特别小的潮汐。 |
| 5. | The set of tectonic cracks on down beam is beneficial to anti - seism along the longitudinal and side long of aqueducts
拱架下弦杆分缝断开的做法对纵、横槽向抗震的最终效果是有利的。 |
| 6. | The fatigue strength of bottom chord node board , which is sensitivity to fatigue , is calculated by fem method
在此基础上，确定了节点板疲劳计算应力。之后，对钢吊车桥架的下弦节点板进行了疲劳强度验算。 |
| 7. | On days around neap tides when the moon is at its first or last quarter , however , tidal ranges become small and sometimes only one high and one low tides are observed
每个月的上弦或下弦，潮差却变得很小，这个时期叫做小潮。有时在小潮期间，每日只有一个涨潮和退潮。 |

| 10. | The biggest difference from the usual down bearing arch structure lies in this points that the four tectonic cracks on its two down beans ca n ' t constrain the level forces
它与常规的下承式拱架支承结构的最大区别在于它的两道下弦杆设置了四道断缝，从而使下弦杆失去对拱脚水平力的约束作用。 |
