In this paper divided the river network into two types: treelike network and annular network,and use time sequence observations on few observation points as the inversion of information, verified use of genetic algorithm inverse of the entire river networks roughness is feasible.

本文将河网分为环状和树状两种不同复杂的情况，把河网中部分观测点的时序列数据作为反演资料，验证了利用遗传算法反演整个河网中所有河段的糙率是可行的。

The main set of "Bliss Most Sunshine Day" is at Nantou's Lemidi Hotelm because this is situated at the nice sceneric area, the filming crew was unfearful of the tiredness, decided to come here for the set, hoping to use the "city promotion" method to promote Nantou, sharing some of Nantou's beautiful scenery.

主要拍摄场景锁定在南投米堤饭店的「幸福最晴天」，因地处於风光明媚的「太极美地」环状风景区，让剧组不惜辛劳，决定来此取景，并希望能藉由「城市行销」的模式，将南投风景优美的一面传送出去。

Results indicated that introducing some ring-structure into UF molecule during the synthesis could efficiently improve the water resistance of UF resin. The Uron ring would form if reaction temperature was more than 75 degrees C, and the higher Uron content was obtained at pH 8 and 85 degrees C in the absence of catalyst when the reaction time was long enough.

结果表明：通过在脲醛树脂合成中引入Uron环等环状结构物质能够有效提高脲醛树脂胶黏剂的耐水性；当反应温度高于75℃时，反应产物都生成了一定量的Uron环物质；在pH值为8左右、温度控制在85℃、不使用催化剂、尽可能延长反应时间的条件下，尿素与甲醛成环化反应生成的Uron相对值最多。

He shipped his oars and brought a small line from under the bow. It had a wire leader and a medium-sized hook and he baited it with one of the sardines. He let it go over the side and then made it fast to a ring bolt in the stern. Then he baited another line and left it coiled in the shade of the bow.

他搁下桨，由船头下拿一条小鱼线，上面有一段铁丝线和一个中型鱼钩，他把它装上沙丁鱼的鱼饵，然后把它从船边放下去，再固定在船尾的环状螺钉上，接着，他装上另外一条鱼线的饵，把线卷好放在船头的阴影处。

The existence of surface dangling bonds often resulted in nano-silicon particles conglutinating with each other to form chain or ring. Nano-crystal often emerged between two particles.

由于纳米硅颗粒表面悬键的存在，所制备的纳米硅颗粒常常相互粘连成链状或环状；互相连接的的两颗粒之间出现纳米晶被共用现象。

The practice shows that the formwork system, which is composed of the annular formwork, radicalized steel tubes and movable bearing plates, has the advantages of reasonable design, safety and reliability, simple structure and convenient construction.

实践证明，这种由环状模板、辐射状钢管和可调支托组成的模板体系设计合理、安全可靠、结构简洁、施工便利，配以先进的施工方法和严格的质量控制，可以实现高精度的结构尺寸控制，提高工程质量。

From the air Beijing reads like a belt of modernity that encircles a historic center, all embedded in a broad zone of dormitory blocks. These living quarters define the majority of the cityscape and as such are arguably the essence of the 'real' Beijing. Yet this expanse of the capital seems to fall between the cracks of the planning debate.

从空中俯瞰，北京是将历史文化中心层层包裹的现代化聚居环状带，中间是宽大的方格状居住小区（这种居住形式是北京城市形态的主要内容，也就是被称为&老北京&的象征，但在规划中，这种形式仍然极富争议）。

Calyx adnate to the ovary, limb annular to cupular, entire or shortly toothed, persistent.

短的或的对子房，环状到杯状，全缘的冠檐贴生的花萼齿，宿存。

Lisa, like Rick, Karen, and Rem, was strapped on her back to a kind of gurney, with her head positioned beneath a thick and heavy-looking ring-shaped device that resembled a scaled-down version of an MRI scanner.

丽莎和瑞克、凯伦还有雷一样，都被绑在一张轮脚病床上平躺着。她的头部摆在一台外形厚重的环状设备下方，那东西的样子像个缩小的核磁共振扫描仪。

In order to surmount the problem of slow reaction rate of the Baylis-Hillman reaction, we employed N-tosylated imines as the electronphile.

因为醛和环状烯酮的反应很难进行，我们便用活性更高的亲电试剂磺酰亚胺代替醛进行Baylis-Hillman反应，取得了很好的结果，反应速度得到了很大的提高。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.

集团所属工厂主要生产多用钳、烤具、刀具、剪刀、厨具、花园工具、美容套等五金产品，年生产总值3000万美元，产品价廉物美、选料上乘、质量保证，深受国内外客户的青睐
