If an additive of B less than 1.37 at.-%, some of B atoms solid-dissolved interstitially into matrix and distorted the lattice, thus the lifetime of positron in matrix dilated; the others of them segregated on vacancy-like defects and formed" filling effect", thus the mean lifetime and S parameters decreased. If B added up to 2.22 at.

在Ni_3Al合金中加入少量硼(≤1.37％)时，一部分硼原子以间隙方式溶解到基体中，使晶格发生畸变，导致基体中正电子寿命增长；另一部分硼偏聚到空位型缺陷上，产生&填充效应&，导致平均寿命■和S参数下降。

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.
