Introduction The Non Linear Optical (NLO) materials are attracted by the science and technology because of the variety of applications like frequency shifting, optical modulation, and optical memory for the emerging technologies in areas like telecommunications, signals processing, and optical interconnections[1,2].
Hence, organic materials are optically more nonlinear than inorganic materials [4].
The obvious one was to develop hybrid organic-inorganic materials, known as semi organics [6].
For better applications of NLO materials, wide optical transparency is an essential property.

According to the requirements of design and construction, SCC of C30～C60 can be produced by selecting materials used and adjusting the amount and composition of composite binder, the dosage and composition of high performance chemical admixture as well as W/B, based on the reasonable component of SCC with volume.
Now concrete is a kind of engineering material widely used.
Filling SCC without vibrating can guarantee the quality of concrete filled steel pipe column; it is easy to construction and much cheap to compare with using grout materials.
Using SCC is economical to compare with using grout materials.
According to the condition of raw materials from the ready-mixed concrete plant, we determined the amount and composition of composite binder and the dosage and composition of chemical admixture of SCC （see table 7）, based on the experiment of preparing concrete.

Introduction With sound development of computer science and artificial intelligence, e-learning will become increasingly important in network education or learning after class.
Because fields related to basic science and methods of solving problem belong to the objective maturity theory, so intelligent tutoring belongs to automatic processing of objective maturity problems.
The system can serve as not only a tool for the students learning and tutoring, but also an assistant to teachers inquiring relative material.

MgF2 (n = 1.38) and SiO2 (n = 1.46) are employed as low refractive materials, while the prominent high refractive materials are TiO2 (n = 2.35-2.55), Ta2O5 (n = 2.17) and ZrO2 (n = 2.1).

Such structures can change the physical and chemical properties of materials, e.g., low-reflective surfaces, tribology, and biological applications [2].
Materials and Methods The ablation of mechanically polished titanium was performed in the air with a femtosecond fiber laser machining system (Figure 1a).
It can be seen that the ablated area is covered with protrusion nanostructures due to the rapid melting and solidification of materials.
Then, the ablation threshold of materials (Fth) can be determined by Eq.(6).

However, the Chlorine-containing and Bromine-containing materials have obvious disadvantages such as irritative and corroded gases will form during combustion, therefore, the halogen-containing flame retardants are gradually being abandoned for the more and more intensity awareness of environmental protection.
