在水中的

A water molecular gel can be formed by the aggregation and self- assembly of gelator 4,4-bissteaiylarnide diphenyl ether at very low concentration. The microcosmic morphology, thin fiber-like structure, was observed from atomic force microscope and TEM of the gels.

通过原子力显微镜以及透射电子显微镜对水分子凝胶的微观形态进行了表征，表明凝胶因子可以在水中聚集、自组装成延伸的螺旋缠绕细纤维结构，并且得出了纤维束的平均直径在100nm左右，平均孔径在100nm左右。

Lesson fourteen Saturday Night and Sunday Morning星期六的晚上和星期日上午 by Alan Sillitoe Text 14-1 He sat by the canal fishing on a Sunday morning in spring, at an elbow where alders dipped over the water like old men on their last legs, pushed by young sturdy oaks from behind.

在春天一个星期日的上午，他坐在运河边钓鱼，在他附近，赤杨树被后面生长着年轻茁壮的橡树向前推挤垂人水中，像垂死的老人一样。

A man who had been 9）soaked in water, and 10）smothered in mud, and 11）lamed by stones, and cut by 12）flints, and stung by 13）nettles, and torn by 14）briars; who limped, and shivered, and glared and 15）growled; and whose teeth chattered in his head as he seized me by the chin.

看上去他曾在水中浸泡过，在污泥中忍受过煎熬。他的腿被石头碰伤了，脚又被小石块割破，荨麻和荆棘的利刺使得他身上伤痕累累；他一跛一跛地走着，全身发着抖，还瞪着双眼吼叫着；他嘴里的牙齿在格格打战，然后一把抓住我的下巴。

Hydrogen bond that are the glue holding groups of water molecules together are so plentiful in water that they play a large role in determining its properties.

在水中，存在着大量的将水分子胶粘在一起的氢键，因此氢键在决定水的特性方面发挥了巨大的作用。

On the other hand the effect of the wind on the gunnels may make it more difficult It is easier to jump in and out of the boat with low sides especially for an older person or when the boat is in deeper water, but it is also easier to fall over the side in a sudden jerk of the boat.

另一方面风的作用在gunnels 也许使它比较困难它比较容易跳跃进出小船与低边特别是为一个比较老的人或当小船是在比较深的水中，但它并且比较容易下跌在边在小船的一个突然的jerk 。

Because the concentrations of heptachlor, aldrin, o, p-DDT, p, p'-DDE and p, p'-DDT in SPMD are lower than those in water, these contaminants are not suitable to be sampled by this SPMD. The results of field experiment done at the Liangshui river prove the feasibility of SPMD used in groundwater monitoring. But detailed work is needed to be done in order to explain some unusual field experiment results.

七氯、艾氏剂、o，p-DDT、p，p'-DDE以及p，p'-DDT组分在膜中的平衡浓度远小于它们在水中浓度，不适于用此种半透膜取样器进行富集；在凉水河岸边的野外实验结果也验证了半透膜装置监测地下水有机氯农药的可行性，但其个别组分的结果出现异常，需要在该地区进一步开展工作进行研究。

The humpbacks, which can grow to more than 50 feet, spend most of their time under water and can dive for up to 30 minutes, so being at the right place at the right time to see them requires skill and luck.

该座头鲸，它可以长到50英尺以上，耗费了大量的大部分时间在水中，可以潜水长达30分钟，所以在在正确的时间正确的地点，看看他们需要技巧和运气。

At most of the points, the group recorded less than 20 nanograms of PFOA per liter of river water, but it reached 456 nanograms in the Ina River in Hyogo Prefecture and 140 nanograms in the Yodo River in the city of Osaka.

在大多数监测点，检测表明：每公升水中，PFOA的含量为20毫微克，在Hyogo的Ina河中含量为140毫微克，而在大板的Yodo河中含量高达456毫微克。

Tonglu: composite or pure copper radiator heating system in the use of one-pipe is dangerous, because one-pipe system, high-speed hot water would have a copper corrosion, should carefully chosen.

然而由于钢制散热器怕水中的氧气，它对供热系统要求很严格，在不安全的系统中会出现腐蚀（腐蚀点大部分在管壁上，而不在焊接部位）；而另外一个事实是，目前我们国内的许多采暖系统还不是很完善，虽然国家对采暖水质早有规定，但仍有许多物业不能按标准执行。

Relatively thick, highly protective films of boehmite, aluminum oxide hydroxide AlOOH, are formed in water near its boiling point, especially if it is made slightly alkaline, and thicker, more protective films are formed in water or steam at still higher temperatures.

比较厚的薄水铝石，高保护膜，氢氧化铝硬铝石，在水中形成接近沸点，尤其是如果它是由弱碱性，和由于铝生产的氧化形式的腐蚀状况而定，其识别厚，更形成保护膜在水或蒸汽在更高的温度。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
