查询词典 hollow

Hitherto, we had never been on such a long excursion,and we were all very much excited as we set out for the hilly expanse of thehinterland behind the river, up and down we walked all day, from hill to hollow.pleasant as the scenery was, the area was economically backward, with nothingmore than little homesteads, where small-time farmers would still be doingthings like mend the hinges on their barn doors, hoe the soil, hollow out somepiece of wood to make a simple tool or hoist the hay onto their carts byhand.

那之前，我们从来没有进行过如此长距离的远足，我们向河后面的内陆多山的广袤地域出发时，都非常激动。一整天，我们在山峰和山谷之间上上下下。虽然这个地区景色宜人，但经济落后，除了小农舍外没有别的，那里面，尚未脱贫的农民可能还在做着修畜棚上的铰链、锄地、挖空木头做简易的工具或徒手把干草吊到马车上之类的事情。

Dehydration process based on hollow fiber composite membrane is one of the crucial and effective methods to remove water vapor from industrial gases such as light hydrocarbon, compressed air, natural gas and so on. Dehydration of propylene with VP method was studied in the thesis. We prepared the PVA/PS、CS/PS and PVA-CS/PS hollow fiber composite membranes by spread method. The permeation behavior of water vapor among coagulable light hydrocarbons through composite membranes and asymmetric membrane was researched by vapor permeation method. Also a differential mathematical model was established which can describe dehydration of gas phase propylene.

加劲肋空心管钢筋混凝土无梁楼盖是一种较新型的空心无梁楼盖体系。

The formation mechanism of the hollow and helical fibers was proposed. During the heat treatment, the hollow fibers could be formed when the inner gel of the thinner precursor fibers was separated from the center and contracted to surface. However, the helical fibers could be generated when larger gel fibers were broken helically under thermal stress in the process of gel decomposing and contracting.

分析了中空纤维和螺旋纤维的形成机理，直径较小的前驱体纤维在热处理过程中内部凝胶向表层迁移收缩形成中空纤维；螺旋纤维是由直径较大的前驱体纤维在热处理过程中产生的强大的热应力导致纤维产生螺旋破裂形成的。
