事实上，我们在三种最常用的实验室仪器——天平、移液器、pH计及过程检测、食品检测技术等都在全球市场中处于领先地位；同时我们还是自动化化学领域的开拓者。

These data indicate that coelomocytes are capable of producing and releasing NO and that NO is a chemical mediator that has been consered as a host defense weapon of phagocytes through eolutionary time.

这些数据显示体腔细胞具有产生和释放NO的能力，并且NO是一个在以吞噬作用为主体防御武器而在进化过程保留下来的化学中介。

By using the results from systemical petrography, X-ray powder diffraction, and EPMA analyses on the run products from experimental simulaion under constant temperature and pressure, we have explored the paragenesis for the pelites suffering metamorphic dehydration under high pressure condition, the process and mechanism for these metamorphic dehydration, and the relation between the components for garnets, one of the major phases in the paragenesis, and the experimental conditions including pressure, temperature, and chemical compositon in a system.

由恒温、恒压实验产物系统的岩相学、X射线粉晶衍射和电子探针分析，揭示了天然泥质岩发生高压变质脱水作用后的矿物相组合，确定了泥质岩高压变质脱水作用的过程和机理，以及主要矿物相石榴子石的组成与压力、温度和体系化学组成的关系。

Using analyses of the surface chemical species formed on palladium in both conditions of flowing oxygen and the ammonia oxidation reaction,it is confirmed that the surface of palladium,at temperatures above 800℃,is a multilayer structure with the bright palladium metal surface being overed by a thin layer of palladium metal vapour and then by a layer of palladium oxidevapour.

本文分析了在流动氧气氛和氨氧化反应过程中Pd的表面化学状态，表明在800℃以上温度Pd的表面应是1种多层结构：光亮的Pd金属表面复盖着一层薄的Pd金属蒸气，Pd蒸气上又复盖着一层PdO蒸气。

The addition of computer user makes waste paper grow in quantity, changing in the process of printer black white and ink box, discard more plastic, metals and chemical material, this and photograph of concept of the office that do not have paper are contrary to, also make bad news material becomes another issue that nots allow to ignore.

电脑用户的增加使废纸增多，在更换打印机墨粉和墨盒的过程中，丢弃更多的塑料、金属及化学物质，这和无纸办公室理念相悖，也使耗材成为另一个不容忽视的新问题。

The liquor is treated by twostep basicity modulation and magnetic field effect, obtaining basic zinc carbonate.

利用化学分析、X衍射和扫描电镜对有关过程及产物进行检测。

In order to investigate work performance of a micro HCCI free-piston engine, Matlab was applied to simulate its single-impact combustion process. A Zero-dimensional numerical model incorporating global chemical kinetics, heat transfer, blow-by and a perfect gas model were developed.

为研究微型HCCI自由活塞发动机的工作性能，应用Matlab软件对其单次冲击的燃烧过程进行仿真建模，分别建立考虑传热、漏气的零维总包化学动力学模型和理想气体模型，并将仿真计算结果与试验结果进行比较。

To introduce the production technology and process of galvanizing steel wire for bridge cable with homemade wire rod.

介绍国产盘条生产桥梁缆索用镀锌钢丝的工艺技术、制造过程，分析研究有关技术要点，指出国产82B盘条的化学成分、理化性能及夹杂物含量与进口盘条相差不大，通条性和稳定性有待进一步提高。

By means of FTIR, the cellulose of walnut shell was liquefied and degraded under acid catalyst in the presence of phenol firstly.
