In the determination of methyl acrylate,butyl acrylate and methyl methacrylate in ambient air,the sample was absorbed with active carbon and resolved with carbon bisulfide,and then determined by GC.After the qulitation by retention time and quantitation by external standard method,the good linearity and low detection limit were got.

测定环境空气中的丙烯酸甲酯、丙烯酸丁酯和甲基丙烯酸甲酯时，气样采用活性炭吸附，用二硫化碳解析，直接进气相色谱仪检测，根据保留时间定性，外标法定量，能获得良好的线性和较低的方法检出限，不仅精密度、灵敏度和重复性良好，而且可操作性强，易于在环境监测系统中推广。

In a routine test, these points are marked by center punch, but, if a more detailed test is to be carried out, the extension is measured by an instrument called an extensometer, which produces the gauge points when it is attached to the test-piece.

在常规测试中，这些点用中心穿孔机标记但是，如果要进行更仔细的测试，延伸量要用名叫引伸计这种仪器进行测量，当引伸计连接试样时，它产生标距点。

Most people consider the return current when considering a fully differential circuit, but when considering the more usual circuit where a signal is referred to 'ground' it is common to assume that all the points on the circuit diagram where the ground symbol is to be found are at the same potential.

分析差分电路时，绝大多数工程师都会注意到返回电流，但对于常见的所谓单端电路，即所有信号采用相同参考点的电路，往往会认为电路中所有标有参考点符号的地方电平都相等。

Snow in 1959, in theory, the general education should be to make up for the limitation of the academic mind caused by the excessive subdivisions of disciplines. Currently, the curriculum of general education in Taiwan University is often used as the professional standard as to the concept in contents, or with science and natural sciences related fields, it may even be set as a leading role in balance seeking. It is; therefore, doubtable that while college education devotes in breaking the barriers of knowledge or academic disciplines, and attempts to establish enriched yet systematic general education, at the same time, helplessly returns to the breakthrough of academic condition described by C.P. Snow where "the Humanities" and "the Science" still confront anxiously. This would not only fail to achieve the consilience in knowledge but also lead to a possible fracture.

P Snow在1959所提出「种文化」的概上进发展的话，那麼通教育在上应该是弥补学科分工过细、导致学术心受到限制的现象；然而目前台湾的大学通教育，由於经常被当成与「专业」相标举的内容概，甚至是被定成与工或自然科学等相关域寻求平衡或对话的角色，因此免让人怀疑：当大学教育致於打破知或学科的藩篱，并且试图建丰富而有系统的通教育时，是否无且吊诡地重新走回史当时所描述并尝试突破改变的学术况－「人文」与「科学」依然充满紧张与对，知仅难以达到融通、甚至陷入另一种断的可能？

During the design of the line graticule, we did not use the ruling technique on glass, but selected Wwire to make the LOS and welded two electrodes at the two ends respectively. This design can avoid any possible error caused by the replacement of the crossline graticule observation when a multispectral optical system is tested.

该装置十字分划线的设计未采用常规的玻璃刻线工艺，而是选取电阻率较高的钨丝制成十字分划线，并在分划线的两端焊上电极，避免了测试时由于更换十字分划线靶标而可能产生的误差。

The very center of a dartboard has a small red dot. This dot is called the bull's-eye. When you play darts, you want to hit the bull's-eye because you get a lot of points.

标靶的正中心有个小红点，这个点叫做「bull's-eye」，射飞镖时要射中红心才能得很多分。

Moreover, analytic hierarchy process are used to determine a priority vector in the evaluation of customer satisfaction indices, and the scales, the computation of a priority vector, group decision, the consistency test and adjustment of a judgment matrix in AHP are studied and improved.

顾客满意度指数测评时，用层次分析法确定权重，对层次分析法的标度、权重计算、群决策、判断矩阵的一致性检验与修正5方面进行了研究与改进。

Under the experimental conditions, the evaluation of catalytic activity on direct decomposition of NO show that the presence of Cu is necessary for improving activity at 600~800℃ among La0.9Ce0.1Fe(subscript 0.8-x)Co0.2YO3(Y=Cu, Zn, Ni) series, and in which L.a0.9Ce0.1Fe0.7Co0.2Cu0.1O3 has the highest activity, the conversion of NO decomposition maintains 80% and nearly 100% at 750℃. H2-TPR result proves that the higher activity is related to the mobility of lattice oxygen which is beneficial to the reproduction of active site for NO decomposition.

在实验条件下，对NO的活性测试结果表明，L0.9Ce0.1Fe(下标 0.8-x)Co0.2YO3(Y=Cu， Zn， Ni)系列催化剂在600~800℃范围内，掺杂Cu的复合氧化物具有较高的催化分解活性，其转化率始终保持在80%以上，反应温度为750℃时，几乎100%转化。H2-TPR结果证明，其催化分解活性高的原因是Cu的掺入使晶格氧活动性增强。

Pasley considers this view oversimplified because neutrality was not a goal of early national newspaper editing even when editors disingenuously stated that they aimed to tell all sides of a story.

同时，类比反义标题标删除也屏蔽了只能在这两种题型中考到的局部单词，加重了考生在打定GRE时回想单词的累赘。

These data indicate that the tempering hardness change show as two obviously different stages, i.e. fast decrease and slow decrease, during austempering for quenched and tempered steels. This change rule can be described with a double exponential distribution functional relationship: H=aesuperscript -b(Tt+cesuperscript -d

这些数据表明，调质钢等温回火时的硬度下降表现为快速下降和缓慢下降两个明显不同的阶段，这一变化规律可以用双指数函数H=ae上标-b

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。

In slot 2 in your bag put wrapping paper, quantity does not matter in this case.

在你的书包里槽2把包装纸、数量无关紧要。
