Pure water is clear, achromaticity, natural water often showing a certain color, which mainly comes from plant leaves, bark, roots, humus and soluble inorganic minerals and sediment, su*ce water polluted by industrial waste water will make the water color extremely complex.

纯净的水是无色透明的，自然水时常呈现出一定的色彩，它主要来源于植物的叶、皮、根、腐殖质和可溶性无机矿事物和泥砂等，地面水受工业废水污染后可使水色变患上极为复杂。

The mast,erected at the forward cabin door,Was a bamboo pole ofno great thickness that bent with the strength of the wind,pokingthe bellying sail out over the side.

篷杆竖在船头舱门的地位，是一根并不怎么粗的竹头，风越大，篷杆越弯，把袋满了风的风篷挑出在船的一边。

Results of some laboratory studies of genistein have also been mixed, but most have shown favorable results, Bergan said, demonstrating that genistein can inhibit a variety of cell molecules including tyrosine kinases, which activate proteins by attaching them to phosphate chemicals.

结果，一些实验室的研究金雀异黄素也有好坏参半，但大多数表现出良好的结果，伯根说，这表明金雀异黄素能抑制多种细胞的分子，包括酪氨酸激酶，激活蛋白质将它们附加磷酸盐的化学品。

The leaves,pedicel axillary bud,pedicel linternode,stem tip and root tip of butterfly orchid were used as explants,and the best explant and culture medium were screened by testing different culture medium with hormone combination.

以蝴蝶兰的叶片、花梗腋芽、花梗节间、茎尖、根尖为外植体，通过对蝴蝶兰组织培养的不同类型的基本培养基及各种激素配比进行组合试验，筛选出蝴蝶兰组织培养的最适外植体及其培养基配方。

It will be feasible to build a pocket calculator "that will be more powerful than, and almost as fast as, the $9 million Cray-1", built by Cray Research Inc. in Chippewa falls, Wis., and recognized as the mightiest computer in the world.

Fairchild 照相器材公司副会长 C莱斯特霍根认为，到 1985 年将有可能制造出"功率超过价格为 900 万美元的 Cray-1，但计算速度与其相差无几"的"袖珍计算器"，而 Cray-1 是威斯康星州 Cray 研究公司制造的并被认为是世界上功率最大的计算机。

The forward kinematics is analyzed by choosing one of the mechanisms which have one, two,three or zero angle constraint.Wherein,3-CCC is a new parallel mechanism which has three angle constraints and three distance constraints, Calay\'s formular and direction cosine matrix are used to describe the rotation matrix respectively.By setting Dixon\'s and Sylvester\'s resultant with the three angle constraint equations respectively and using parameters replacement to deal with the distance constraint equations,the 64 order input-output equation of the forward kinematics is obtained under both of the methods.Numerical example confirms these theretical results and the motion simulation is shown in VC++ by integrating OpenGL.

3对高小山提出的广义并联机构进行了研究，以其中具有角度约束的并联机构进行了分析，选取具有一个、两个、三个和零个角度约束类型中各一个机构进行了运动学正解求解，其中3-CCC是一种全部由圆柱副构成的具有三个线线角度和三个距离约束的新型并联机构，文中分别用Calay公式和方向余弦两种旋转矩阵建模方法对其位置正解进行了分析，通过对三个角度约束方程分别构造Dixon结式和Sylvester结式，以及对三个距离约束方程进行变量代换分别导出了位置正解输入输(来源：4040ABC论文网www.abclunwen.com)出方程，得出64组位置正解，并使用数值算例验证了其全部根。

But these days, he was a little embarrassed. He only looked at his watch in private. It was because of the old leather strap on the watch.

只不过这些日子他有点儿难为情，只在没有的时候才掏出表来看时间，因为挂在表上的是一根旧旧的皮带子。

Jim would love it. Jim loved his watch. But these days, he was a little embarrassed. He only looked at his watch in private. It was because of the old leather strap on the watch.

III. If there is an expander roll, it can not be installed in the place of the tight roll of paper machine; instead, it should be adjusted to the first sink roll where the cornerite is comparatively small after pressurization, otherwise corrugations might occur.

如有展毯辊，展毯辊不能安装在纸机张紧辊的位置，而应调整到出压榨后，毛毯包角较小的第一根导辊的位置，否则易造成毛毯打折。

As Focus Enhancements faded into the rear-view mirror, Jeff Berkowitz and Matt Jacobs scoured corporate America as Jim and I, sitting five feet apart and facing each other, moved mountains and molehills from dawn to dusk.

吉姆喜欢追涨；对下跌的股票兴趣不大。由于在摩根斯坦利的从业经历，我喜欢&淡化&市场，逢低买入，逢高卖出。这是一个狭路相逢勇者胜的游戏，有人赢，就有人输。

Fancy gold-plated dangling earrings with facetted White Opal crystals.

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
