类

You can see from the Woodwind and Brass classes that once you've implemented an interface , that implementation becomes an ordinary class that can be extended in the regular way.

你可以通过从 Woodwind 和 Brass 类看出来：一旦实现了某个接口，这个实现类就变成了一个你可以直接继承的类。

Then from the perspective of the hearer, the acceptive characteristics of the rhetoric of double meanings are uncovered from the acceptive order, acceptive type and acceptive degree. Mainly according to cooperation principle and relevance theory, the judgment and recognition of the rhetoric of double meanings, the regularity taking on when its deep meaning is revivified and cognized are induced; and at the same exhibiting specifically the meaning reasoning process of the acceptor of the rhetoric of double meanings of polysemy, synonymy, and antonym.

塔什库尔干碱性岩带主要由碱性正长岩类、碱性花岗岩类和碱性—偏碱性花岗岩类组成，代表性岩石类型为霓辉石正长岩、透辉石正长花岗岩和黑云母二长花岗岩。

The number of differentially expressed genes was 71 at 24h, and 62 at 72h. The metabolisic gene class was the majority among all the differentially expressed genes, and the next was transportational、differentiation and adhesional gene class by turns.1.2. RT-PCR verification of the known HIF-1 targeted genes and proliferation related genesIn the 131 differentially expressed genes, we found 7 known HIF-1 targed genes (ldha、aldoa、eno1、gapdh、tpi1、pgk1、bnip3) and 5 genes (dnaja2、ccnb1、tgfβ2、ccng1、rgs7) which were related to proliferation and cell cycle.

对差异表达的基因进行基因功能分类发现：代谢类基因最多，其次是运输类基因、细胞分化及黏附类基因。1.2 RT-PCR验证HIF-1靶基因和增殖相关的基因由于我们的前期实验证明了低氧促NSC增殖是有HIF-1参与的，我们对131个差异表达基因中，7个已知的HIF-1靶基因(ldha、aldoa、eno1、gapdh、tpi1、pgk1、bnip3)和5个与细胞周期和增殖相关的基因(dnaja2、ccnb1、tgfβ2、ccng1、rgs7)做RT-PCR验证。

Adhibit the information entropy theory into fuzzy merger and get over a good manyartificial controlled factors in parameter inputs or pausing conditions of commonmerger arithmetic.

将信息熵理论引入模糊聚类中，克服了一般聚类算法，在参数输入、停机条件上存在诸多人为控制因素，能取得较为满意的聚类效果。

After a further analysis based on the empirical results,a trial probe on the cognitiveprocessing mechanism of the problem representation of the word problem in two types of MLDwas made by the author.The MRD performed much poorer than the MLD only in the mostdifficult equation listing of word problem and the medium and most difficult problemrepresentation of word problem,which showed no difference in computation and comprehensionof simple meaning of the problem,but the gap between two types of MLD became wide as afunction of difficulty and cognitive loading.It indicated that the MLD only had some advantage over MRD for they used more cognitive skills to solve the problem.

基于以上实验的结果，对两类数学困难小学生的应用题问题表征的认知机制作如下推断：混合型数学困难学生仅在高难度水平的应用题列式成绩和中高难度水平应用题问题表征水平上比单纯型数学困难学生得分显著低下，表明两类数学困难小学生在计算能力与理解简单题意的能力上并无差异，但随着难度提高，认知负荷加重，两类数学困难学生在应用题解题上的差异得以突显，表明当需要运用更多的认知能力解决问题时，单纯型数学困难学生比混合型困难学生更具优势。

To cope with the problem, two major context-clustering methods, agglomerative and tree-based, have been widely investigated.

为了解决这个问题，有两个主要的上下文相关的聚类算法被提出，它们是合并聚类和决策树聚类。
