The limits of non－ degenerate quasilinear equations (i.e. the regularizing problems) are established. The uniqueness theorem is proved by the contraction property of the solution.

Chapter 4 at first concerns a doubly degenerate parabolic inequality.A Liouville-type theorem is obtained by carefully choosing desired test functions for weak solutions of the inequality problem.

第四章首先考虑一类双重退化抛物型不等式，通过适当选用试验函数的办法得到此抛物不等式弱解的Liouville型定理。

Though we are not so degenerate but that we might possibly live in a cave or a wigwam or wear skins today, it certainly is better to accept the advantages, though so dearly bought, which the invention and industry of mankind offer.

当然我们没有退化到今天住窑洞，住尖屋，或穿兽皮的程度，自然罗，那付出了高价换来的便利人类的发明与工业的贡献也还是应该接受的。

The BLAST programs were used for searching protein and DNA databases for sequence similarities. The BLAST result showed that it was a new sequence and similar to zebra fish DNA sequence and some fish reverse transcriptase. But it has small homology of CYP 19 gene sequences that have been in Genbank.In addition, sequences were amplified by RT-PCR with using degenerate primers that weredesigned against CYP4 sequences.

另外，还根据昆虫CYP4家族的特异性氨基酸序列及P450超家族的共同特征序列，采用另一对简并引物，同样进行有关研究，结果显示：疣荔枝螺不同组织的RNA中都含有一长468bp左右的序列，这同样是一段新序列，与部分物种的CYP4存在一定的相关性，可能在螺体内起一定重要的作用，但具体功能有待进一步研究。

One of them went plundering; the other set every building and everything in it all abaze! Judging by what they did, we know that the victors could degenerate into robbers.
