Therefore, it has the important scientific research value in studying the relationship between the changing of the parameters (including the temperature, the humidity, the grain radius and so on) and the electricity and radioactivity of the medium. Applied the count statistics and the numeral value analysis, the paper analyzes, concludes and contrasts the data sufficiently through the experimentation, and acquires the following results that the resistivity and the polarizability both have the negative relationship with the temperature variety of medium from 0℃ to 200 ℃. The parallactic poalarizability is consistent with the temperature variety in the plan as well as the section, but their trends are exactly opposite. Power supply voltage has no considerable influence to the resistivity and polarizability by using duality variance analysis, however, the detecting depth and the plan position influence them greatly. Different AB/2 interval that increases by degree does not influence variance and the average value of the resistivity and the polarizability remarkably. By using the least double multiplication, the relationship of temperature-time-the influence radius of the fire source is carried up by the mathematic drawing up. After discussing their correl ation, I educe the influence radius of the fire source and carry out the 'trend analysis and forecast to the spacial changing of the temperature and the parallactic polarizability in the end.

If the height of bump is higher, the radius of bump is smaller, and the thickness of wire , substrate and chip is thicker, the strain of package without underfill is smaller. If the height of bump is shorter, the radius of bump is bigger, the thickness of wire is thinner, and the thickness of substrate and chip is thicker, the strain of package with underfill is smaller.

在应变方面，较高的凸块高度，较小的凸块半径，较厚的线路、基板和晶片厚度将对未填胶构装体有较小的应变值；另外较矮的凸块高度，较大的凸块半径，较薄的线路，较厚的基板和晶片厚度将对填胶构装体有较小的应变值。

Similarly, when you set the Radius value, you want to set the width and height of the underly- ing Ellipse so that each is double the value of the radius, which you can do in the property setter.

Analytical formulae are presented for the first time to describe the shift in the resonance wavelength of LPG in response to etching of the fiber cladding or a change in the external refractive index. The accuracy of the formula is confirmed by comparision with numerical simulations and experimental results. We demonstrated that the resonance wavelengths of an etched LPG are more sensitive refractive index than those of an unetched grating. The bending properties of long period fiber grating written in different type fiber are studied experimentally. The transmission peaks and the central wavelength of LPG change with the bending of the fiber. A new peak appears at the shorter wavelength when the fiber is being bent. The changes of the peaks are different for different photosensitive fiber. Those properties have broad application foreground in fiber sensors and tunable filters.
