SF-1 is a kind of oilless slide Bushing made of the PTFE composite material,Which is a copper-plateed steel plate on to which a

SF-1是由PTFE复合材料制成的无油润滑轴承，是将锡青铜球粉烧结到镀铜板上形成多孔屑，然后将PTFE和铅

The corresponding numerical algorithm is developed. The responses of pearlitic steel BS11 and single-phase hard-drawn copper subjected to asymmetrically cyclic loading are analyzed.

采用上述方法，分析了珠光体钢(BS11)和单相冷拉铜板受非对称循环载荷作用下的响应，分析结果和实验结果一致。

There was an obvious phenomenon of mechanical occlusion on the cold spray coating interface, and the rolled coating had the phenomenon of metallurgical bonding; The structure of cold-sprayed coating is dense. The poriness of the cold-sprayed coating gradually reduce as the coating's thickness increase.

结果 涂层界面形貌的不同反映出两种涂层的结合机理不尽相同，冷喷涂层界面出现明显的机械咬合现象，而轧制涂层以冶金结合为主；冷喷涂层组织致密，孔隙率随着喷涂厚度的增加逐渐降低；冷喷涂层的表面粗糙度高于轧制覆铜板，有必要对其进行一道轧制处理，改善涂层表面平整度。

"Every little bit helps," he said, and he scooped the money out of the drawer.

每个铜板都很管用，」他说道，并且把抽屉里的钱拿走了。

The spalling results simulated by LS-DYNA2D hydrocode are consistent with the experimental results.

借助LS-DYNA2D程序模拟了铜板在爆炸加载下的层裂过程，计算结果与试验结果基本一致。

ABSTRACT: This assay initially discussed the researches and developments of syntheses and reforming of the tetratlycidyletyer of tetraphenol ethane applying to the copper clad laminate and simply explained its principles and functions of UV-ray shield and fluorescence.

本文对四官能环氧树脂[1，1，2，2—四乙烷四缩水甘油醚]的合成与改性及在覆铜板中的应用作了初步探讨，并对其屏蔽紫外线与产生荧光的机理作用作粗浅的阐述。

It is used as a selection method like tossing a coin.

它被当作一种像掷铜板一样的选择方法。

In this dissertation, several novel halogen-free fire-retardant epoxy-based copper clad laminates were developed. Two kinds of phosphrous-containing epoxy resins were synthesized by different method. A novel nitrogen-containing curing agent 2,4, 6-tri (phenol-methylene -amide)-trizone was synthesized for preparing high-performance epoxy polymers, and the synthesis kinetics, cure kinetics and mechanism of MFP cured with DGEBA have been investigated by Differential Scanning Calorimeter and in situ Infrared.

本论文以开发新型无卤阻燃环氧树脂基覆铜板为目标，合成了两类结构不同的含磷环氧树脂以及一种新型的含氮固化剂2，4，6-三-均三嗪，考察了它们合成过程中的影响因素，用DSC和原位红外光谱法探讨了MFP固化环氧树脂的固化反应机理。

A smooth 60-mil-thick HDPE geomembrane, underlaid by the CCL, was placed under the cell separation berm.

土工一顺利 60 米尔厚 HDPE 膜，由覆铜板，underlaid 被放在细胞分离天然。

You want something out of the poor devil, so you put a garland around his neck. That is not respect, it is merely the coin with which you buy and sell in the market.

你想从那个可怜的穷人身上得点东西，所以你在他脖子上套个花圈，但花圈不代表尊敬，它只是一个你在市场上买卖所用的铜板。

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。
