Dielectric, piezoelectric and electrmechanical coupling properties of PZT and PSZT systems at high Zr content region were studied. The feature of high Kt and low Kp of PZT-based materials near F-AF phase boundary was exploited and examined, and electromachanical coupling anisotropy Kt/Kp is higher than that at the morphotropic phase boundary , Kt≥0.40, Kt/Kp≥3. 0. This phenomenon can be realized by electric field -induced AF-F phase transition and explained by coupling effect of two-sublattice in antiferroelectric unit cell.

对不同方向上青杨天牛种群空间异质性研究表明：天牛卵、幼虫和成虫在四个方向上的半变异函数拟合的模型相同，但空间依赖范围却不同，属几何性的各向异性。

The fractional anisotropy values of white matter in schizophrenia patients and normal controls were measured respectively in frontal and the splenium of corpus callosum. Independent-samples t-test for non-paired data was used to test the differences between schizophrenia arid controls for FA values. Correlated analysis was applied to reveal the correlations between FA values in frontal and the PANSS scores.
