Compared with the old variable displacement wobble plate compressor, it has compacter structures, smaller size, lighter weight, higher efficiency, higher reliability, lower noise, higher rotational speed operation and wider range of displacement.

变排量斜盘式压缩机是继变排量摇板式压缩机之后的一种新型变排量压缩机，具有零件少、结构紧凑、尺寸小、重量轻、效率高、耐久性好、振动噪声特性好、高转速运行和排量调节范围宽等特点。

The second trend is continuate innovating of structure, material, processing technique, working accuracy and product quality. Both equipment reliability and viability increasingly high,and equipment weight increasingly lightness. Hydraulic dynamical bearings and static force bearings are widely applied in large-scale equipment, which bring mill smoother start-up and transmission than other bearings do. Fueling injection fittings are used to lubricate gears, which prolong gears' working lives.

近年来磨机发展的第一个趋势不再是磨机结构的大型化，而是从降低能耗和钢耗的角度来改善磨机工作性能；第二个趋势是不断改进结构，提高材质，完善加工工艺、加工精度、产品质量，设备的可靠性和耐久性越来越高，设备重量越来越轻，在大型设备中普遍采用液压式动力和静力轴承，使磨机的启动和传动更加平稳，齿轮润滑使用喷油装置，延长了齿轮的工作寿命。

The PBT fiber is soft, friction-resistant, crispate, and it has good elasticity of elongation and compression.

PBT纤维具有较好的弹性、尺寸稳定性和良好的耐久性，染色性能优异。

Porous macromolecular polyethylene characterized by light and porous fits the tissue ingrowth, but it is instability and dearticulation.

钛质人工听骨生物相容性和组织亲合性佳、耐久性好、重量轻、可塑性强、不易脱位，是一种有推广前景的听骨修复材料。

The durableness problem of glue joint is discussed.

并定性地讨论了胶螺接接头的耐久性问题。

Integrative system makes it easy to install and maintain, which in turn ensure its high durably and efficiency.

使配置的机组具有很高的耐久性和更高的工作时效。

Not only it requests the concretes to satisfy the design intensity durably, and so on, but must satisfy the pipeline to transport mixes to the concretes the request, namely the request concretes mix the thing to have the good pumpability.

它要求混凝土不但要满足设计强度、耐久性等，还要满足管道输送对混凝土拌合物的要求，即要求混凝土拌合物有良好的可泵性。

Due to slope cable bears barely alternative load longtime in nature environment, it is easy to corrosion and wreck. Seriously, the bridge is possibility to collapse in strictness air empoison, water pollution, seashore and ocean surroundings. Therefore, to study cable's corrosion widely and to inhibit corrosion process are very important for increase endurance and safety of bridge construction.

由于斜拉索长期承受交变载荷并暴露于自然环境中，特别是大气污染严重地区、水污染严重地区、海滨及海洋环境，极易发生腐蚀破坏，严重者还会因坍塌而造成生命及财产的巨大损失，因此，全面研究桥梁拉索的腐蚀，阻断腐蚀的成因，对提高桥梁结构的耐久性与安全性具有重要意义。

Self Consolidating Concrete, more widely used in Europe but used with increasing frequency in the US, is more flowable than conventional concrete, but can be just as cohesive and achieve the same durability and strength.

自密实混凝土是一种在欧洲已经大规模的建筑材料，其在美国的推广使用也呈上升趋势。这种混凝土比普通混凝土流动性更强，同时却有着同样的耐久性和强度。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
