Transformer Design and Experiment Data
There is a RCT, whose core is made of a ultrachrystallite material, shown in Fig. 5 with an outer diameter D1, internal diameter D2, height h0.
It can be seen from Fig. 6, in lower frequencies, the theoretical values better fit experimental data; as frequency increases, higher than 8 MHz, the experimental data gradually deviates from the theoretical value.
At higher frequencies of about 24 MHz, the theoretical value and the actual data come to a minimum value at the same time.
The 3 dB passbands of the theoretical values and experimental data overlap approximately.
Fig. 9 is the data of the RCT comparison experiment containing uniformly coil winded CT without shielding box, uniformly coil winded CT with the shield box and specially coil winded CT without shielding box .Through comparison: ① the CT with a shield box is significantly less impacted by the rise of frequency than the one without shield box.

The applicability of the second_order equation was proved by the linear dependence of the experimental data in the ln(1/θs–1/θ0)/T2–1/Т coordinates, where θ0 is the degree of the complete coverage of the surface.
The data in analog mode representation was obtained (MS plotted).
The decrease in intensity is connected with the reduction of copper oxides included in the catalyst.
DME desorbs in the temperature range 473-673 K (Тmax=553 К), which is also consistent with our data obtained in the catalytic experiments to determine the effect of temperature, which showed a maximal yield of DME at 553 K.
These data provide the basis to develop the technological standards to produce DME from CO and H2 combining two reactions in a single reactor.

After the accident, the accident point reduction in capacity, if the upstream traffic demand exceeds the capacity, bottlenecks will appear the returning wave, when the accident exclusion, the "wave start" while there follow the vehicle reaches the tail, returning wave is lasting, both exist and are in motion backwards.

There were three specimens for each age of the cubes to obtain the average data for more accurate results.
The 28 days compressive strength of eggshell concrete was used, and the result of each set of data was compared with the experimental data obtained in this study.
From Figure 5, the experimental data had a similar trend when plotted with other sets of data from design codes.
The value of experimental data had significant differences with the China and India code, but was accurately represented by the expression from EC-2.
However, an unusual sharp drop was observed for 15% ESC compared to other sets of data.
