两个两个地

The structure theorem is obtained by defining "ternary ordered partition method" which is used to choose the test-sets of the first $k$ tests, and by defining two operations and two relations on feedback sequences; The isomorphism classification theorem is strictly proved by virtue of the structure theorem, thus the complicated problem of discussing $3^k$ possible search domains is reduced to the relatively easy problem on $k+1$ representative search domains; By the techniques of "super-coin construction method" and "image-union method", the search problem on $k+1$ representative search domains is reduced to the simple verification of several conditions on finite space of small cardinality.

通过引入用于选取前$k$次试验的试验集的"三元有序剖分法"以及关于反馈序列的两种运算和两种关系，得到了结构定理；基于结构定理严格地证明了同构类定理，从而将必须针对$3^k$个搜索域的复杂问题转变为讨论$k+1$个具代表性的搜索域的相对简单的问题；通过"构造超币法"和"并像法"等技术手段，将关于$k+1$个具代表性的搜索域的搜索问题转化为简单的关于势非常小的有限空间的几个条件的验证问题。

With 19 members in common (soon to be 21 when Bulgaria and Romania join the EU), the two bodies are like Siamese twins awkwardly joined together.

有19个国家（当保加利亚与罗马尼亚加入欧盟，很快就有21个国家）同是两个组织的成员国。两个组织如同连体双胞胎一般别扭地连在一起。

Judged by the important valuecalculated based on the individuals with DBH≥3 cm, major tree species were Cyclobalanopsis glaucoides, Pistacia weinmanni f olia, Neolitsea homilantha and Olea yunnanensis.

依据两个10000m^2森林样地的调查，在两个样地内分别记录到植物95科142属的163种和70科110属的125种，其中，草本物种最多，乔木次之，藤本较少。

Wait two months, then take on a partner you trust. Reapply for the program under this new partner's name and address,(now especially possible given Google's automatic deposit program).

如果真的得地很想重新加入，你只有一条最基本的得地路可走：换域名、银行帐号、IP地址、ISP还有站点设计，等两个月，然后请个你可以信赖的得地朋友，用你朋友的得地名字和地址重新申请帐号。

More widely, the number of "electoral democracies"(those with tolerably free and fair elections) dropped by two, to 119 (thanks to four demotions and two promotions).

更广泛地看，&选举民主制国家&（带有相当自由和公平的选举）的数字减少两个，为119个（因为四个降级，两个升级）。

Or, rather, it employs two ring-shaped half-pipes that rotate with respect to one another (the lower one remaining fixed while the upper one revolves along with the building). The joints between the half-pipes have rubber seals to stop the contents leaking, and each half-pipe has a vertical pipe connected to it, to introduce or dispose of the fluid concerned.

或者更确切地说，它由两个相对旋转、各只有一半的环形钢管组成（在下面的半个环形钢管固定不动，而在其上的另半个环形钢管则跟着房子一起旋转），两者的接合处由橡胶材料封住以防管内物外漏，此外两个环形钢管各有另一根管道垂直接入，来引入或导出相关的流体物质。

Besides I dropped 2 lurkers at the expansion which killed almost all of his scvs.

另外我还在他的分矿处投了两个地刺，这两个地刺几乎杀光了他所有的SCV。

Comparative study on two levels of population and modules of mutualspecies in the two stations demonstrates that feature index tend to diminish suchas height,tussock amplitude,size,number,density and dry weight;and thegrowth analysis index incline to increase such as RGR、ULA、chlorophyllcontent and effectiveness of plant multi-leaves of the populations and DULA、DUMR、DAGA and DRGRa of the modules;and the dynamic curves of thepopulations and the modules also tend to steadily increase along with thetemperature ascending,heat accumulation and combination between water andheat in moderate-temperature steppe from fierce fluctuation alongside naturalprecipitation in warm-temperature steppe,illustrating that the transformabletendency from increasing the numbers of tussocks and tillers in order to expandthe resource range to seize in warm-temperature steppe to steadily improve drymatter production function of the populations and the modules in moderate-temperature steppe.

两个不同热量型研究站点共有种种群与构件两个水平的比较研究表明：随纬度增加和气温降低，种群与构件高度、丛幅、大小、数量、密度和干重等特征指标趋于降低和减少，而种群RGR、ULA、叶绿素含量和植物多叶性与构件DULA、DUMR、DRGR和DRGRa等生长指标则趋于增加，种群与构件的生长动态曲线也从随天然降水而剧烈波动趋向于随气温升高、热量积累和水热配置状况而稳定增长，说明各共有种从暖温型草原区增加植物种群与构件的大小和数量以扩充资源利用范围向中温型草原稳定地提高种群与构件的干物质生产性能的方面转变的趋势；同时，物质与能量的分配也从较多地投资于繁殖器官产生大量后代以适应未来降水的不可预期变化趋向于同化系统的构建和干物质生产效能的提高以抵御低温和干旱对物种生存的威胁，充分显示出不同温度条件及其水热组合对植物种群形态结构和生长繁育模式的显著影响及其响应特征。

Said the two to their tutor,"Is it harder to toot or to tutor two tooters to toot?"

那两个学吹笛地问导师：「吹笛难，还是教两个学吹笛地人吹笛难呢？

For main-belt objects this can occur after the object has been observed on two or more nights at four oppositions (although this depends on the number and distribution of the observations as well as their quality); NEOs can receive a number after two or three well-observed oppositions.

对于主带小行星，只要在4个冲日内观测到两个或更多的夜晚（虽然这依赖观测的数量和分配以及观测的质量），就可以获得正式编号；对于近地小行星，只要获得两个或三个比较好的冲日数据，就可以获得正式编号。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。

Ever since our world has been a world, native forests have been indiscriminately exploited by man.

自从我们的世界一直是世界原生森林被任意剥削人。
