There were four
compression ratios for different ply numbers of LVL, 8.1% for eight-ply samples, 18.3% for nine-ply
samples, 26.5% for ten-ply samples, 33.1% for eleven-ply samples, respectively.
Introduction Laminated veneer lumber (LVL) is an engineered wood product manufactured from veneers that are rotary peeled, dried and laminated together with parallel oriented grains under heat and pressure with a waterproof adhesive.

The number of layers was fixed at 03, but the immersion time varied between 01 to 10 minutes.
To obtain with higher thickness films, the sequence of dipping, drying and then dipping again was performed a number of times.
This might be attributed to the slight increase in grain size and the homogeneity of the structure.

Introduction
kidney beans (Phaseolus vulgaris L)belong to Papilionaceae, Phaseolus,which are not only rich in nutrients, but also have medical effects, not only traditional grains, but also modern healthy foods, and are popular in both domestic and foreign markets.
In this study, 10 g of soybeans were soaked in water and 90 ml of water was added to grind, after filtration, 2% of which was added to the kidney bean cultivation juice, cultivate at 37℃, and determine the number of the living bacteria.
Tomato juice, wort, and soybean milk was added as growth promoting substances to the kidney bean cultivation juice at the amount of 3%,after cultivation at 37℃ for some time, the living numbers of bacteria was shown in Figure 4.
Figure 4 Growth curve after addition of growth promoting substances From Fig 4, we can see that all the substances added can improve the growth of lactic acid bacteria, after the addition of soybean juice, the increase of the bacteria number was very obvious, because there was very rich nitrogen compounds in soybean juice, which had significant effect on the growth of lactobacillus, so soybean milk was selected as the growth promoting substance.

Introduction
Lead zirconate titanate (PZT) perovskite ferroelectric ceramics have been considered for a number of
applications in actuators and nonvolatile memories [1,2].
After all, space charges and the local alignment of defect dipoles could be easily formed at domain walls or grain boundary under driving field.
Different samples were used for different cycling numbers.
(a) Correlation between d33 and ε before and after fatigue under all cycling fields; (b) d33 and ε as a function of cycle number.

The results also indicated that the estimation accuracy depended on the threshold of sampling numbers, if the numbers are less than the threshold, the sampling density is in contact with the spatial estimation accuracy, if the numbers are more than the threshold, the density of the sampling numbers is improved, but the estimation results are not proportional to the density.
If the numbers are more than the threshold, the density of the sampling numbers is improved, but the estimation result is not proportional to the density, as illustrated in Figure 4 and Figure 5.

According to this, dielectric material has well conducting grains separated by highly resistive grain boundaries.
On the application of electric field, space charge accumulates at the grain boundaries and voltage drops mainly at grain boundaries [42].
Koops proposed that grain boundary effect is more at low frequencies [42].
Moreover, the dielectric loss tangent also depends on a number of factors such as stoichiometry, Fe2+ content, and structural homogeneity which in turn depend upon the composition and sintering temperature of the samples [46].
