片段重复

结果表明在水稻的12条染色体的九条之间发生了七次片段重复事件，并且大部分的重复发生在2、3、10和12号染色体上。

The results indicate that segmental duplication events had occurred in rice chromosomes and six chromosome segmental duplications events occurred were found on 9 of 12 chromosomes . Moreover , most of duplications were concentrated on chromosome 2,3,10 and 12 .

serpin基因拷贝与片段重复及转座元件的相关性分析表明，在家蚕微孢子虫11个serpin中，有6个基因与转座元件存在极显著相关性，有两对基因是片段重复产生的多拷贝。

The relative analysis between serpins and segmental duplications and transposable elements indicated that there are six out of eleven serpins have significant correlation to the TEs , and two pairs of serpins were produced by segmental duplication .

后来的程序员无法站在以前程序员的肩膀上，而是制造了大量无用的片段和重复。Scheme程序员之间要彼此重复。

A great deal of unnecessary fragmentation and duplication of effort : instead of standing on the shoulders of previous programmers , Schemers step on each others'toes .

许多修改就是在用于JDBC访问的Java代码片段中重复修改某个行，如果使用的是Hibernate之类的数据库持久层，那么这些修改都是可以省去的。

Many of the changes were simple repetitive one line changes in a series of Java code for JDBC access that is unnecessary if a database persistence layer such as Hibernate is used .

另外有些基因，特别是由许多相同的碱基对短片段不断重复而所组成的基因，是很难很好地测序的。

And some parts , particularly those where the same short pattern of base pairs is repeated over and over again , remain difficult to sequence well .
