Slurry preparation: a key to upgrade CMP efficiency Chao-hui Zhang1,a, Hong Lei 2, Xiao-li Hu 3 1 School of Mechanical, Electronic and Control Engineering of Beijing Jiaotong University, Beijing 100044, China 2 Research Center of Nano-science and Nano-technology, Shanghai University, Shanghai 200436, China 3 Shanghai Dianji University, Shanghai 200245, China a zhhzhang@bjtu.edu.cn Keywords: slurry preparation; chemical mechanical planarization; material removal ratio Abstract.
In modern integrated circuit (IC) industries, CMP is a widely used technique to acquire nano scale flatness of the materials with high porosity, low-k values [2].
Larger particles will result in higher material removal rate, which can easily be ascribed to the mechanical effects.

The paper mainly analyzes biological hydrogen production system in the aspects of ecology and engineering control.
Engineering monitoring.
ORP is affected as follows: First, when evolved oxygen partial pressure increases, the ORP rises and vice versa .Second, the Eh is decreased due to some reductive materials that are produced by microorganisms in the course of redoxing and metabolization of organic substances.
The optimum HRT of bio-hydrogen production reactors had better to be at 4～6 h according to hydrogen production capacity and retention ability of suspending materials.

By using of the principle of the reverse engineering and CATIA V5 software, the torque rheometer mixer rotor used in high polymer material test is designed.
Reverse Engineering of Mixer Rotor A complete reverse engineering process mainly includes data acquisition, data processing and curve surface reconstruction.
Because the reverse engineering will involve many things and face lots of problems during implementation, it’s only system engineering.
The whole processes of reverse engineering please see Fig.2.

During the long engineering project construction period, involving a combination of human, financial and material, and that different works, every link and each phase is mostly high altitude, open, crossover operation, which hide safety risks and result in high probability of safety accidents, so these characteristics determine the importance of safe and civilized production.
Therefore, the influence factors of engineering construction safety are worth studying.
However, there are not many studies on the engineering construction safety influencing factors at present.
The research object of this study is a series of variables can not be directly observed which involve the engineering construction safety influencing factors.
We contact with safety or technical directors of the department, safety managers, construction managers, supervision engineers, technical engineers, field work personnel and other engineering construction safety related personnel.
