Print the contents of the vector and the array created in the previous exercise.

输出习题 4.34中建立的 vector 对象和数组的内容。

Like a vector, an array holds a collection of objects of some type.

与 vector 类型相似，数组也可以保存某种类型的一组对象；而它们的区别在于，数组的长度是固定的。

The Vector class lets you access and manipulate a vector — an array whose elements all have the same data type.

使用 Vector 类可以访问和操作矢量（即所有元素均具有相同数据类型的数组）。

In particular, readers accustomed to using C or Java might expect that because vector elements are stored contiguously, it would be best to preallocate the vector at its expected size.

具体而言，如果读者习惯了 C 或 Java 的风格，由于 vector 元素连续存储，可能希望最好是预先分配合适的空间。

Progressive Transductive Support Vector Machines has some drawbacks such as slower training speed,and unstable learning performance,a Progressive Transductive Support Vector Machines learning algorithm based on hypersphere structure is proposed.

针对渐进直推式支持向量机（Progressive Transductive Support Vector Machines，PTSVM）算法训练速度慢，学习性能不稳定的问题，提出一种基于超球结构的渐进直推式支持向量机算法。

Random access in a vector can be efficient because each access is to a fixed offset from the beginning of the vector.

由于 vector 容器的每次访问都是距离其起点的固定偏移，因此其随机访问非常有效率。

Methods: The coding region of superoxide dismutase was amplified using PCR method from the E.co1i genome. The PCR product was cloned into PUC19-T vector and sequenced. In addition, the cloned coding region of Mn-SOD was inserted into the expression vector PET-28a to form the recombinant plasmid PET-28a-Mn-SOD and was then transformed into E.coli BL21 for expression.

用PCR方法从大肠杆菌2号基因组中扩增Mn-SOD基因编码区，克隆到pUCm-T Vector，测定核苷酸序列；再将基因编码区克隆到原核表达载体PET-28a，构建含Mn-SOD基因的重组表达质粒，转化到大肠杆菌BL21中进行IPTG诱导表达。

A novel method for image edge detection is presented based on information measurement and Support Vector Machine, which is called ISEDM (Information measure and support vector machine edge detection method).

将信息测度和支持向量机结合在一起，提出了一种新的图像边缘检测方法（information measure and support vector machine edge detection method， ISEDM）。

We know that the size of an empty vector is zero, and evidently our library also sets capacity of an empty vector to zero.

由此可见，空 vector 容器的 size 是 0，而标准库显然将其 capacity 也设置为 0。

The RT-PCR product was inserted into pTG19-T vector and transformed into E. coli successfully. By blastn, the sequence results of Kunming mus musculus were in complete accordance with the conservative sequence of Genbank NR_003278 (791bp-1153bp). By Blastn in NCBI, the sequence with little difference among animals was confirmed to be conservative. After Blastn, fourteen complete CDS coding for different animals were chosen. According to VECTOR NIT 9.0 software, the similarities between Kunming mus musculus and bos taurus, homo sapiens, erinaceus europaeus, cricetulus griseus, sus scrofa, dasypus novemcinctus, rattus norvegicus, rabbit, equus caballus, macaca fascicularis, didelphis virginiana, monodelphis domestica and vombatus ursinus was 67%, 100%, 100%, 36%, 100%, 100%, 67%, 100%, 100%, 92%, 99%, 99% and 99%. In the phylogenetic tress constructed with the forteen 18S rRNA by Treeview, the Kunming mus musculus clustered with cricetulus griseus, sus scrofa and rabbit, which was nearer to cricetulus griseus and was most far away from macaca fascicularis.(3) After sencodary structure analyses of 18S rRNA of mus musculus, an oligonucleotide fragment for RNAi was designed and synthesized, which was transformed into plasmid, and restriction enzyme analyses and sequencing results should the expression plasmid pGPH1/ GFP/Neo-mouse-sh 18S rRNA were constructed for RNAi successfully.

结果①通过RT-PCR检测显示18S rRNA基因在小鼠卵巢组织和单个GV期、MⅠ期卵母细胞中均有表达，且在未成熟卵母细胞中，MⅠ期的表达明显强于GV期的表达；②RT-PCR产物克隆测序结果显示：昆明小鼠18S rRNA基因保守区序列与基因库序列[NR_003278保守区部分(791bp～1153bp)]完全一致；Blastn比对结果发现：在不同物种中差异较小，选出14种生物18S rRNA全序列经VECTOR NIT 9.0软件分析，提示昆明小鼠18SrRNA与牛、人类、刺猬、中国仓鼠、猪、犰狳、褐鼠、兔子、马、食蟹猴、负鼠、短尾猊、袋熊的18S rRNA的相似率依次为67%，100%，100%，36%，100%，100%，67%，100%，100%，92%，99%，99%，99%；Clustal 1.81和Treeview构建出的分子进化树表明：在上述14种生物中昆明小鼠与中国仓鼠进化关系最近，与兔子、猪聚成一簇，与食蟹猴进化关系最远；③根据18S rRNA二级结构设计并合成RNA干扰寡核苷酸片段，重组质粒经过限制性内切酶及测序表明成功构建了pGPH1/GFP/Neo-mouse-sh 18S rRNA干扰表达质粒。

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

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
