The load carrying capacity and antiwear property of S,P containing benzotriazole derivative (BM 3) were evaluated using a four ball test machine,and compared with those of zinc salt di(T 202 ) and amine salt of complex ester thiophosphate (T 307 ). The antiwear mechanism of BM 3 were studied by investigating the chemical states and the mass fraction of elements on the rubbed surfaces using X ray photoelectron spectroscopy and electron probe microanalysis and the thermal decomposition products using gas chromatography mass spectrograph.

在四球机上对照评价了含硫、磷苯并三氮唑衍生物（BM－3）和二丁辛基二硫代磷酸锌（T202）及硫磷酸复酯胺盐（T307）的承载能力和抗磨性能，用X射线光电子能谱仪和电子探针微分析仪等对磨斑表面元素N，S和P的存在形式及表面膜的组成进行了分析，用气相色谱－质谱联用仪对BM－3的热分解产物进行了分析，并且还对其极压抗磨作用机理作了探讨。

This paper determined the olfactory respones of Tetranychus viennensis to different plants odors with "Y" olfactometer and petri-dish, volatiles from leaves of different plants were absorbed with SPME and analyzed with GC-MS (gas chromatograph-mass spectrometer). At the same time, the effects of different host plants on the development of Tetranychus viennensis were determined by means of the leaf-dish rearing method , in addition, the contents of some chemicals in the leaves of different plants were also determined.

本文用"Y"形嗅觉仪法和培养皿法测试了山楂叶螨Tetranychus viennenis Zacher对不同植物气味物质的嗅觉反应，并利用固相微萃取SPME吸附、用气相色谱—质谱联用仪GC-MS(gas chromatograph-mass spectrometer)分析了不同植物叶片的挥发性物质成分：同时采用海绵水盘法饲养山楂叶螨，研究了不同植物对山楂叶螨生长发育的影响，并测定了不同植物叶片中一些生化物质的相对含量。

And based on the mass spectrometry raw data, protein identification was performed by application of the Mascot or SEQUEST search program, respectively.

利用质谱分析得到的原始数据，MALDI-TOF通过Mascot软件搜索，高效液相色谱-质谱联用仪通过SEQUEST搜索SWISS-PROT的人非冗余蛋白质序列数据库。

The unirradiated and irradiated samples are analyzed by FTIR, SEM, PGC/MS and TG. At the same time, the gas products after irradiation are analyzed by GC/MS. The relationship of gel fraction of irradiated samples in air with the dose and the compression property and stress relaxation ratio along with the dose are determined.

采用傅立叶红外分析仪、扫描电镜、裂解色谱质谱联用仪以及热失重分析仪等对辐照前后的样品进行了分析，同时使用色质联用仪对辐照后产生的气体进行了分析，并且测定了空气中辐照试样的凝胶含量与吸收剂量的关系以及在室温下试样的压缩性能、应力松弛率与吸收剂量的关系。

Because of these benefits, numerous types of array-detector-based instrumentation have been developed, including optical and mass spectrometers.

由于有这些好处，多种基于阵列检测器的测量仪器得到开发，包括光学的和质谱仪。

But in the 1950s the first sophisticated mass spectrometers were developed, capable of measuring isotopes in small samples.

但是上世纪50年代发展出的精细质谱仪能够测定少量样品中的同位素。

Ion beams are used in a variety of applications, such as with mass spectrometers and ion implanters.

离子束用于各种应用场合，诸如，质谱仪和离子注入机等。

Note: Most mass spectrometers calculate the reciprocal of the above and state it as a percentage, which is equally valid.

注意：大多数质谱仪能够计算上面式子的倒数并且以百分比的形式表示出来，其实也是同样有意义的。

Process mass spectrometers take measurements very quickly by jumping to each of the nominal mass positions.

过程质谱仪通过跳到定义的质量位置实现快速测量。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
