Restraining measures The measures for restraining and eliminating stray lights in blue-green laser optical system are as follows: (1) The aperture diaphragm is in combination with VOF diaphragm and Lyot diaphragm to reduce the total numbers of key surface and the irradiated area, and then lessen the stray light radiation in optical system[7].
The dope can diffuse and absorb the stray lights by the rough surface and porosity, and the effect will be best if the grain dimension of dope is near the blue-green wavelength.

The general formula of mullite solid solution is AlVI2AlIV2+2x Si2-2xO10-x, where x (0.17 ≤ x ≤ 0.88, usually 0.17 ≤ x ≤ 0.59) is the number of oxygen atoms loss in the unit cell, the density of 3.11-3.26 g·cm-3 [1-3].
But a very little quantity and very fine crystal grain size of mullite formed at the time, mullite is not detected.

• The relations between operating variables of the different powder preparation methods and the characteristics of the resultant powder: grain size, shape, inter- and intragranular porosity, and hardness
This has been extremely useful for companies, owing to the great number of models that are being made and the reduction in production lot size, together with increasingly stringent end product quality requirements.

Especially the ancient timber structure not only has a unique structural system, but also a large number and beautiful shape.

The increasing of anode density also can prolong the utilization of anode in the condition of constant size which will reduce the replace number, and lessen effect of artifical action, and keep the balance of electric field and magnet field, and keep a reliable and efficient operation of aluminum electrolysis cell.
The batch formula of carbon anode consist of four grain size (5-8mm, 2-5mm, 1-2mm and powder).

As a result, the final phase composition of a silica material will be determined by the type of raw material used, its grain size distribution, type of mineralizer as well as the course of firing process.
In the conducted experiments the number of X-ray impulses reached the value of 70000 counts (Fig. 1 and 2).

These parameters are: density of energy flux, cavitation number, grain size of the workpiece, flow rate, temperature of the liquid, surface tension, vapor pressure of the liquid, tensile stress applied on the workpiece, gas (air) content in the liquid, the amount of pH in case of using water as the liquid [6,7].

With the increasing number of international cooperation among different organization and department, the attributes belonging to a user usually are monitored by different authorities.
Attribute-based encryption for fine-grained access control of encrypted data.

Organelles were gathered around the cell wall and the number of chloroplasts reduced, equally the space between the cells became smaller.
The important changes of chloroplasts were that (1) chloroplasts became round, and were aggregated with different levels; (2) large vesicles were produced; (3) chloroplasts were broken; (4) grana were degraded, the stacking height of grana were reduced, broken chloroplasts were piled up together irregularly; (5) starch grains were aggregated.

Also in this experiment, molar ratio of S/Zn in precursor solution is 3, it is conducive to produce a large number of Zn vacancies.
It is due to ratio of surface and bulk phase atoms increase with the grain size decreased.
