Topics covered include: waves in media, equivalence principle, duality and complementarity, Huygens' principle, Fresnel and Fraunhofer diffraction, dyadic Green's functions, Lorentz transformation, and Maxwell-Minkowski theory.

它包含以下的主题：介质内的波、等效原理、对偶性质和互补性质、惠更斯原理、菲涅耳绕射与夫琅和费绕射、双重格林函数、洛伦兹变换以及马克斯威-明可斯基(Maxwell-Minkowski)理论。

It implies that there is no much sense in seeking regular Riesz waveletbase in the space because even if we find one,its duality cannot be a regularwavelet and there is little usefulness in applications.

虽然我们还不知道〓中是否存在正则的Riesz小波基，但这一结论说明，如果存在的话，它的对偶决不是正则小波，这在应用上是很不方便的。

This theorem is obtained by appling the reproducing kernel theory and the duality property of Riesz basis.

第四章中，根据再生核空间理论和Riesz基的对偶性质得到有限区间[0，L]小波子空间上的Shannon型采样定理。

Alpha-1 antitrypsin is the most abundant circulating protease inhibitor in the body, Dr. Lomas said. Its most common deficiency mutation is the Z allele, where the amino acid lysine is exchanged for glutamic acid at position 342 in the polypeptide chain (Glu342Lys). About 1 in 1700 whites of northern European descent are homozygotes for this mutation and thus have plasma antitrypsin levels that are 10% to 15% below normal, he said.

Lomas博士表示，甲一型抗胰蛋白酵素是身体内最充分的循环蛋白酶抑制剂，最常见的缺损突变在Z对偶基因，该处的胺基酸 lysine与麸氨酸在多胜肽链的第342位置交换(Glu342Lys)；北欧血统白人每1，700人有1人是此一突变的同合子，因此血浆抗胰蛋白酵素值比正常低10%到15%。

Influences of substituents on the orientation of the azo chromophores were discussed in detail.

讨论了不同的端基对偶氮生色团在自组装膜中初始取向的影响。

The split between the two groups can hardly be papered over.
