From the themodynamic theory of Devonshire,it was ponited out that the relationship P/χ=P s/C can be regarede as a method to develop the pyroelectric material figure of merit of ferroelectric crystals,i.
从热力学德文希尔理论出发，指出关系Ｐ／χ＝Ｐｓ／Ｃ可作为提高铁电晶体的热释电材料优值Ｍ（Ｐ／ε）的一条途径，即通过提高其自发极化强度Ｐｓ来提高其材料优值Ｍ（Ｐ／ε），并生长出了用大极性分子尿素改性的ＴＧＳ晶体－ＵＴＧＳ、ＤＵＴＧＳ、ＬＵＴＧＳ和ＤＬＵＴＧＳ。
