Introduction As the exploitable utilizable forest stock is lessen, there is great change in the forest resource structure of our country, and the situation so-called “ three more three less ” is happened: less Virgin forest, more plantation; Less big diameter grade timber, more small diameter grade timbers; less precious, high quality and rigid materials, but more fast-growing, inferiority, soft materials.
Test materials are Poplar LVL (Hebei SANLI Wood Products), whose thickness of veneer is about 1.6mm, 21 layers.

Among the various composite nanomaterials, ZnTiO3 doped with some transition metal ions has been widely researched as one of the most promising luminescent materials as a result of its environmental friendliness and low cost [2,3].
In the present paper, we attempt to prepare Pb2+ ions-doped ZnTiO3 nanofibers by using sol– gel processing and electrospinning method, and want to gain a kind of materials with improved photoluminescence properties due to one-dimensional nanostructural properties and high specific surface area.

The distant between the diamond pipes must guarantee the materials free flowing from top to bottom by itself gravity.
According the theory and simulation computation, the distant between the diamond pipes should be bigger than 4d, where d is the max material diameter [3].

There are many theoretical advantages in modifying biomaterial surfaces with the stepwise SSP including: modification of the oxide properties to investigate the relative influence of various physico-chemical features such as surface topography, composition, wettability and thickness; nanostructured multilayer organization of the oxide with biologically relevant molecules; and enhanced bioreactivity of the material.
