1) positivity preserving coercive forms
保正型
1.
In this paper, property of h-transformation of the Symmetric positivity preserving coercive forms are discussed.
通过对称保正型（ε，D（ε））h-变换的暂留性、常返性和不可约性的讨论，证明了对称保正型的暂留性、常返性和不可约性在h-变换下是不变的，由此得到（ε，D（ε））h-结合的m-胎紧m-特殊标准马氏过程的相应性质。
2) positivity-preserving
保正
1.
Construction of positivity-preserving rational interpolation surface over triangle
三角域上保正有理插值曲面的构造
3) first orthogonality preserving operator
第一型保正交算子
6) orthogonally protect
正交保护
1.
Fmoc-Lys(Boc)-OH and Z-Lys(Boc)-OH were prepared from L-lysine by protection of α-amino and carboxy with 9-BBN, acylation with (Boc)2O and then orthogonally protection with overall yield of 80% and 78%, respectively.
以乙二胺为脱络合试剂,制得Nε-Boc保护的赖氨酸,然后再合成正交保护的Nα-芴甲氧羰酰基-Nε-叔丁氧羰酰基-L-赖氨酸及Nα-苄氧羰酰基-Nε-叔丁氧羰酰基-L-赖氨酸,总收率分别为80%和78%。
