先试

All weighing tests should be made in the standard atmosphere for testing textile.after the specimens have been conditioned in the same atmosphere.it may be impractical to condition the specimens in option A or nonconditioned testing may be agreed upon by the purchaser and supplier.when the full rolls or bolts of fabric can not be properly conditioned in a resonable time with available facilities,perform the tests without conditioning and report the actual conditions prevailing at the time of the test.such results may not correspond with the results obtained after testing adequately conditioned specimens in the standard atmosphere for testing textiles.

D1776实际操作的定向试块。纺织品的所有的权衡测试都应该在标准大气压下进行。当试块被置入同等气压的条件之后，或许将试块限制于A选项是不切实际的，而且有可能条件测试并不一定会被供应商和客户认同，当充满凹凸不平和毛刺的织物不能被适当的限制与合理的时间和现有的设施的时候，在没有限制的情况先执行试验并准确的报告在测试时的有力条件。这样得到的对纺织品测试的结果或许会与在真空中得到充分限制测试的结果不相一致。

The standard workpiece of the ring compression test by Lee and Altan will be used in this report. The specimen will first annealed to eliminate the internal stress and then through different ways of machining to produce different roughness of surface and different direction of machining marks. The ring compression test with various lubricants and dry friction were carried out at room temperature. The experiment results were drawn on the diagram of friction factor developed by Lee and Altan to compare the influence of the roughness of surface to plastic forming with or without lubricants.

实验将依Lee and Altan压环试验所用之标准压环试片进行，实验试片先经退火处理消除内应力，再将试片以各种不同之加工方式制作成具有不同的表面粗糙度，与不同刀痕方向之摩擦面，再於常温环境下实施乾摩擦与添加不同润滑剂之压环试验，将实验结果所得之数据绘制於Lee and Altan之定剪摩擦系数图中，以比较其不同表面粗糙度对塑性成形之影响，同时也说明在各种不同表面粗糙度下添加各种润滑剂对成形之影响。

A pound of beef requires around 12,000 gallons of water to produce, compared to 60 gallons for a pound of potatoes. If you're a meat eater, for starters, try cutting out a serving of meat each week. Going vegetarian or vegan is a profoundly meaningful environmental choice

生产一磅牛肉，约需12，000加仑的水，而生产一磅的马铃薯，只需60加仑的水，若您是肉食者，请先试着每周减少一些肉品食用量，加入素食行列或成为全素者，是一项有显著意义的环保之举。

He sampled the pie before making a purchase.

It was found that when writing the lesson plan, 50% of student teachers looked at subject content first. One third of them invented teaching strategies first while only two of them considered children's experiences first.

研究结果发现，超过一半的实习教师表示在试教之前是先构思教材内容之重点，超过三分之一的实习教师先考虑教学目标，有百分之二十的实习教师先设计教学策略，只有两位个案表明会先思考儿童经验。

I suggest you place a trial order first.

我建议你先试订一批。

This will help you to get used to yor teacher's voice. Try listening to and reapeating the tape without reading the words.

你先试着不看单词去听磁带内容，并进行复述。

We can try without training wheels to start.

我们可以先试着不要用辅助轮。

Dad : Maybe it'll be best if you try training wheels first.

爸爸：你先试着用辅助轮或许比较好。

The split between the two groups can hardly be papered over.
