This is an untouched measuring way. The cameras are calibrated in the way of RAC two steps, first. With the polynomial interpolation, the pictures catched from the steel plate are treated to detect the edge in subpixel with a cross window arithmetic operators, which can fit non uniform illumination, keep the edge character and do filter in a better way. Three-dimensional scenery could be rebuilt from the two-dimensional pictures with the methods of least square fitting and contradictorily clairvoyance. Thus, the distance and its variance of two points in the given position of the plate can be achieved. It is expected that this study can provide a new and useful tool to the research on the theory of distortion of line heating.

Using this method, wide dimming range can be achieved with narrow frequency range and constant DC link voltage. And the lamp current keeps perfect sine wave all the time, which means low lamp current crest factor is obtained. Its validity is verified by simulation and experiment.

本章最后提出了一種基于T型濾波器的新型的調光方法18岁禁看网站在线看，采用此方法可以在保持逆變器直流母線電壓和開關占空比不變的情況下欧美在线黄片小视频，只需很窄的頻率范圍就能達到非常寬的調光范圍，而且在整個調光范圍內燈電流都基本上是完美的正弦波国产一区二区精品久久久v，這就意味著可以始終保持很低的燈電流波峰因數(shù)国产日韩欧美午夜福利网站，仿真和實驗結果充分驗證了它的優(yōu)點。

In this paper, we tested moisture adsorption capability of desiccants that were made from corn hull in different humidity and different temperature;we tested reversible adsorption of these desiccants too. The change of appearance of sample grain was validated by SEM and the augment of surface area was validated by mensuration.

To improve the stability of Arcjet discharge plasma in low current and high voltage mode, research on the demand of output characteristics of Arcjet Power Conditioning Unit was conducted. In this paper, based on PWM invertors and current mode control, using MOSFET as the main power device, an Arcjet Power Conditioning Unit was developed. Through adding a closed loop feedback circuit of output voltage, it can make the output characteristics of PCU be positive resistance to ensure the stability of Arcjet discharge plasma. The experiment indicates that this PCU can make Arcjet engine work at high voltage mode (100 V, 10 A) and ensure the stability of arcjet discharge plasma. Finally, it provides the experimental data of Arcjet when working.

As Jeremiah vividly describes the coming invasion wherein the Babylonians would devour the land and its people, he laments for his stricken people who have rejected God's words,and he mourns because of their incurable spiritual disease. Even the balm of Gilead, implying God's gracious and merciful healing touch, could not heal their festering wounds caused by their rebelliousness against the Great Physician, who longed that they would come to Him for healing.
