The shallow ditch beside the road provided little cover, leaving them vulnerable to plunging fire from the hills east of the road.

路边的浅沟提供不了什么掩护，使他们几乎无法抵御从路东面小山上射来的犀利火力。

Further, like most other cases such as gas/liquid membrane contactors, the overall mass transfer coefficients K of this novel membrane contactor in distillation decreased while fiber packing fractions became bigger, which presented a strong relationship between shell mass transfer and fiber packing fraction.

据此可作为膜接触器结构设计的判据，即当膜接触器填充密度较低时，其传质性能主要受中空纤维膜分布不均匀度影响；而当填充密度高时，组器结构对传质的主要影响因素应为沟流和死区。

The temperature dependence of the distribution of the two-dimensional electron gas,the sheet resistance,the ohmic specific contact resistance,and the buffer leakage current are analyzed.

得出了器件饱和电流随温度升高而下降主要由输运特性退化造成，沟道泄漏电流随温度的变化主要由栅泄漏电流引起的结论。

Each run consisted in 30 - min dura-tion and two replications of each of five slopes were assigned.

细沟侵蚀是坡面侵蚀的主要方式，在坡面侵蚀产沙及其输移过程中占有重要的地位和作用。

At the same time, we compare coastal tidal-basin and sandbanks tidal-basin on geomorphology characters, formation causes, style and so on.

在此基础上，探讨了影响潮盆-潮沟系统动态变化的主要因素，即异常水动力事件、海平面上升、海滩围垦、海岸盐沼植被的发育等。

Usually there is only little water in the ditch , but after the flood , it is now knee - dep .

通常这条小沟里的水很少，但洪水后它的水已齐膝盖深了。

3 If the wiring of an appliance is so located that it may be in proximity to combustible material or may be subjected to mechanical injury, it shall be armored cable or in rigid metal conduit, electrical metallic tubing, metal raceway, or shall otherwise be protected.

12.2.3若内部的电线邻近可燃材料或者可受机械外力的破坏，则导线应是装甲电缆，刚性导管，电气金属管，金属沟，否则应加以保护。

The Qaidam Basin northwest reason located at the Qaidam Basin northeast, on the tectonic element belongs to the Qaidam Basin first-level tectonic element vast cliff to be hollow, the Cainozoic Era hollow stable growth, has deposited the great thick this time stratum, under dwarf Luo Tong, does Chai Gouzu to deposit up and down the heavy film hydrocarbon source rock.

柴西北缘位于柴达木盆地西北部，构造单元上属于柴达木盆地一级构造单元——茫崖凹陷，中新生代凹陷稳定发育，沉积了巨厚的这一时期地层，其中中下侏罗统、上下干柴沟组沉积厚层的烃源岩。

The line started from Ningsia in the west, ran along the Chingshui River in the south and terminated at the Yellow River in the east.

在皖南事变前夜，国民党在边区周围已经修筑了五道包括沟墙和碉堡的封锁线，西起甘肃、宁夏，南沿泾水，东迄黄河，绵亘数剩同时，包围边区的国民党军队也增加到二十余万人。

Isolated HSE without LIR or ALN was highly indicative of branch occlusion in this study, and of a partial superficial infarct in the middle cerebral artery territory in the previous study.

而之前的文献还曾报道：仅出现半球脑沟消失征而未出现豆状核低信号征及岛带消失征，还可能提示大脑中动脉部分浅表供血区的梗塞。

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。
