And in China, steel tube tower mainly used in large span engineering.
According to some statistics, there are about 12500kv large span engineering, 12220kv engineering, 3110kv large span engineering.
In the 500kv double loop and multi-loop transmission line, about 20 transmission line engineering used steel tube tower.
In 2005, Liao Zonggao did the research about the problem of the design of steel tube tower in choosing materials, the calculation of connection strength, the connection of steel pipe penetration, the application of high strength blot, the connection way of the sway rod with main material of steel tube tower, and the connection of the steel tube tower with its foundation etc..

Structure design and material selection is the key of weapon design.
The key part is bear bigger force part in shooting.
Material of the counter-recoil frame should be selected for greater yield strength of materials.

Engineering in general is a process-intensive domain.
In this example, the discipline is Software Engineering, yet it is argued that the approach can be applied to any process or set of processes from Chemical, Materials and Metallurgical Engineering.
It is argued that the Behavior Engineering method has broad applicability across Engineering domains as a process verification tool.
Behavior Engineering Behavior Engineering uses a formally-grounded graphical notation with the capability to represent a wide range of processes in unambiguous terms.
Arguably, the generic nature of BE makes it a valuable tool for Chemical, Materials and Metallurgical Engineering or indeed any other that relies on the rigorous application of process.

The application of metal materials in exercise-induced bone injury Jiang Yuan Hou1, a, Shao Qing Zhang2,b and Li Ke1,c 1He Bei institute of physical education, China 2Bao Ding university, China abdxyhjy@163.com, btyxsqz@126.com, cswmhbty@163.com Keywords: Metallic materials; tissue engineering; bone injury in sports Abstract.
With the development of tissue engineering, the biomechanics, materials and engineering theory and methods can be compromised by the modern medicine means abundantly, and it is applied to the medical field gradually, which provided so many research directions and treatment protection for the medicine.
The mechanical effect of material implantation The length of the plate and the distribution of screws are the key factors for the stability of fixation.
For example, different nature of the metal material has the same biocompatibility, corrosion, toxicity, texture and the severity degree of tension, which is the key point to be selected as medical bone metal materials.

The previous protocol uses both probabilistic key pre-distribution in the lower tier of the network architecture and public key cryptography in the upper tier to distribute session keys.
It generates a large pool of random symmetric keys and then preconfigured each node with a number of keys randomly selected from the key pool.
Key connectivity is the probability that two or more sensor nodes store the same key or keying material.
We also consider a public key like RSA algorithm which is known to everyone but the private key is the personal key based on which communication is possible.
