It is an artificial way to extracted genetic material, such as DNA, which is required in a certain donor biological gene materials.
In 1973, they inserted the exogenous gene into plasmid DNA, and mixed the new DNA, introduced Escherichia coli into these mixed materials, which achieved the gene transfer success.
This is the first artificial planned implementation of genetic engineering in the world, which declared the birth of genetic engineering.
In addition, the raw materials used by the genetic engineering are generally renewable and recycled creatures that do not need to consume large amounts of non-renewable resources, and realizes the technology of clean, low consumption, and the purpose of sustainable development.
Measure of Value and Ethical Value Value is about the nature of the self sustaining and development, human factors for all human practice ontology, including any form of materials.

Introduction With the progress of the materials science technology, engineering ceramics have become a kind of advanced material with many merits and been widely applied in the fields of aerospace, science and technology of national defence, computer engineering and so on [1,2].
On the other hand, the mechanical properties of workpiece materials also have important influences on the surface quality [7].
In order to study the surface roughness characteristics of different kinds of engineering ceramics and clarify the effects of lapping parameters on surface roughness, three kinds of engineering ceramics such as Al2O3, ZrO2 and ZTA were chosen as experiment materials, and the contrast experiments of high-speed lapping with and without ultrasonic assistance were carried out in this paper.
The properties of test materials are listed in Table2.

Finite element simulations of an inchworm type piezo-driven rotary actuator Hu Huang1, a, Lu Fu1,2, b, Hongwei Zhao*1,c and Chengli Shi1,d 1College of Mechanical Science & Engineering, Jilin University, Changchun, Jilin 130025, China 2AVIC Beijing Chang Cheng Aeronautical Measurement and Control Technology Research Institute, Beijing 100176, China ahuanghuzy@163.com, bfulu0796@163.com, chwzhao@jlu.edu.cn, dshichengli163@163.com *Author to whom correspondence should be addressed.
Keywords: Finite element simulation, Piezo-driven, Rotary actuator, Key units.
Static and modal analyses of key units of the rotary actuator such as the clamping unit and the driving unit were carried out by finite element simulations to ensure that key units of the rotary actuator have enough strength and good dynamic characteristics.
Due to the disadvantage of limited output displacement of piezoelectric materials, one of key issues for piezo-driven stages is to increase their motion range meanwhile maintain their high motion accuracy.

After hundred years of development, the types of piezoelectric materials develop from the original piezoelectric crystal to the piezoelectric ceramics, the piezoelectric polymer, the piezoelectric composite material and piezoelectric alloys and other materials.
But piezoelectric ceramic materials belongs to brittle material, it will be broken when the piezoelectric materials are closed to the pavement, so we should consider the mechanical characteristics of piezoelectric materials; moreover, pavement will stand axle load for millions of times and even hundreds of millions of times in design working life, too much stress can cause fatigue damage of piezoelectric materials, therefore, not only the theoretical data, but also the material characterization and the coupling of the material characterization and the pavement should be taken in consideration to judge the position of the piezoelectric materials.
