类型

C# basically has kind of two kinds of data, value kind and cite type, when value kind is delivering variable, those who deliver is the value of data, and cite when the type is delivering variable, the variable address that pass.?

C#主要有两种数据类型，值类型和引用类型，值类型在传递变量的时候，传递的是数据的值，而引用类型在传递变量的时候，传的变量的地址。？

Until June 2007, seventy-eight species of Amphibians' complete sequence of mitochondrial genome were presented in GenBank. The gene numbers in the genomes range from 35 to 41; the 78 mtDNA genomes can be divided into 22 types and further clustered as 3 groups based on the gene number, kind and arrangement. The type 4 is a common type among the class Amphibia and other vertebrate, type 8 is common among the three orders of living Amphibia.

对2007年6月13日以前公布于GenBank上的78种两栖动物的线粒体基因组全序列进行了总结、比较和分析。78种基因组中基因的数量从35~41个不等；根据基因的数量、种类及其排列顺序的差别将其分为22种基因组类型，其进而聚为3组，其中类型4为两栖纲与其它脊椎动物的常见类型，类型8为两栖纲中现生3个目的公有类型。

We will investigate the actuality of stony deserts in Guizhou, and divide their types on the basis of their intensity, covering rate of soil and vegetation and amount of species, and stduy the influence factors of forming different stony desert types in more coercing, and explore the ratio of influence factors in the different stony desert areas and the evolutionary mechanism of different stony desert types. Finally,we will stduy the growing conditions and species of arboreous in different geology, land form,hydrology region for natural lithogenic forest and artificial forest, and the natural conditions for failing in many artificial forest,and the reconstruction mechanism in different stony desert type regions.

对贵州石漠现状调查，并根据石漠发育强度、土被、植被覆盖率和物种多少等进行石漠类型分类；对多重胁迫下不同石漠类型形成因子研究，探讨各影响因子在不同类型石漠区的权值；探讨各类型石漠演化机理；选取不同地质、地貌、水文背景区的原生岩生森林及人工造林区对其乔木的立土条件及物种研究；选取贵州经多次造林失败的石山的自然条件研究并探索不同类型石漠区生态重建机理。

Asian (47.4%) and temperate genera mainly constituted by North temperate (50%) and E. Asian (50%). So that the geographical elements are discomplex. In the 25 species of arborous layer, 76% is the middle subtropical zonal type, 16% south subtropical zonal type and 8% north subtropical zonal type, of which the first 6 positions of important value index were all middle subtropical zonal type. This showed that the community was subtropical characteristic. There are 59.5% evergreen and 40.5% deblade of 79 known species in which the mid-phaenerophytes is the first position of all, accounting for 27.8%, and the evergreen broad-leaved species constituted the majority of meso-phaenerophytes which accounts for 15.2%.

乔木层多数优势种为稳定型种群，所以乔木层优势区系成分相当稳定，表明该群落为一种顶极群落。59个种子植物属只有10个分布区类型和4个变型，地理成分不复杂，其中热带分布27属占46.6%，温带分布31属占53.4%；热带分布以泛热带和热带亚洲分布为主，分别占52.6%和47.4%，温带分布为北温带和东亚分布各占50%。25个乔木层树种中，中亚热带地理分布类型的占76%，南亚热带地理分布类型的占16%，北亚热带地理分布类型占8%，重要值指数排列前6名的均为中亚热带地理分布类型，所以该群落为亚热带性质。

D. Declaration of nonprimitive types such as String, Vector ans so on allocates memory space for the object.

但是严格来讲此题的答案有待确定，因为只有原始类型的实例变量和类变量的声明在类对象被创建/类被加载时完成内存的自动分配，而原始类型的局部变量必须显式初始化，从这点来看原始类型的局部变量没有被自动分配内存，SL275中只提出了非原始数据类型的变量必须使用new Xxxx完成内存的分配而没有指出原始数据类型的变量是否在声明时即自动进行内存分配，而从局部变量不能在显式初始化前使用这点来看在声明时没有进行内存分配。

When a catch parameter is a base type, then we cannot know the actual type thrown by a rethrow expression. That type depends on the dynamic type of the exception object, not the static type of the catch parameter.

当 catch 形参是基类类型的时候，我们不知道由重新抛出表达式抛出的实际类型，该类型取决于异常对象的动态类型，而不是 catch 形参的静态类型。

The results showed that 9 pathogen collections of Sporisorium reilianum were divided into 3 pathogenic types in which there were type A with high pathogenicity, type B with moderate pathogenicity and C with weak pathogenicity. Type A were originated in most important corn-grown areas including Changchun ,Jilin,Gongzuling and Changling where corn head smut usually occurs severely, type B were collected from Siping,Tonghua ,Songyuan,Yanbian, and type C were collected from Baicheng where corn head smut usually occurs very lightly.

致病类型A为强致病类型，来源于吉林、长春、公主岭和长岭，是玉米丝黑穗病发生最严重的地区；致病类型C为弱致病类型，分布于白城地区；致病类型B其致病性介于A、C类之间，主要分布于四平、通化、松原和延边地区。

If the body of L is a statement block, if the set formed by the types of the expressions in the block's return statements contains exactly one type to which each type in the set is implicitly convertible, and if that type is not the null type, then that type is the inferred return type of L .

如果 L 的体是一个语句块，如果由语句块中 return 语句表达式的类型形成的集合正好包含一个集合中每个类型都可隐式转换成的类型，那么这个类型就是推导出的 L 的返回类型。

A dynamically typed language can be seen as a statically-typed language with a very permissive type system under which any syntactically correct program is well-typed; as long as its dynamic semantics ensures that no such program ever "goes wrong" in an appropriate sense, it satisfies the definition above and can be called type-safe.

一个动态类型语言可以看作是静态类型语言和类型限制系统的集合，该系统限制了语法正确的程序是类型安全的；如果它的动态语义能够保证在某种合适程度上不会出错，那么它就满足上面的定义，可以称作类型安全的。

It is also known as one of the most poisonous naturally occurring substances.

它也被称为一个最自然发生的有毒物质。

The greatest stress is found at the location on the cross section where V is the largest.
