Pathological changes in biological tissues usually cause changes in their microstructure. Since the second harmonic generation signal is highly sensitive to the symmetry change of the microstructure , SHGI can be used for the early diagnosis of diseases and the monitoring of aftertreatment in clinics.

生物组织的病变往往会引起微观结构的变化，而二次谐波信号对组织的结构对称性变化高度敏感，因此二次谐波成像对于某些疾病的早期诊断或术后治疗监测，具有很好的生物医学应用前景。

The bridge loses balance and sensitive parts have a output signal,which will transform to related current signal after differential magnifying and conversion between current and voltage. Linear 4~20mADC standard signal is formed by compensation of magnifying and non-linear rectified ring circuit ,and second temperature compensation.

Although, in general, the biquadratic term lowers the exchange bias, its role to the coercivity is duplex, i. e., we can tune the biquadratic term to enhance or reduce the coercivity.

一般而言，双二次项耦合的存在削弱了交换偏置，但是它对于矫顽场的贡献是双重的，为此，我们能够通过选择双二次项耦合强度来调节矫顽场的大小。

For example, one of our conclusions is that a nonsingular QSIC has one affinely finite component if and only if the characteristic equation of the two quadrics has two distinct real roots and a pair of complex conjugate roots.

由于两二次曲面的特征方程实根个数及其重数可用精确的计算方法得到，本文分类结果可用于实现对任意两二次曲面的非平面交线拓扑形态的判断。

In this note, we prove a congruence relation on real quadratic fields which relates class number and certain character sum.
