Trellised up 用棚架支撑着 in most tempting show 最诱人的样A fox had fallen into a well, and had been casting about for a long time how he should get out again, when at length a goat came to the place, and wanting to drink, asked Reynard whether the water was good, and of there was plenty of it .

"狐狸和山羊一只狐狸掉在一口井里，转了很久怎样再跳上去，最后一只山羊来到这里，他正想喝水，便问狐狸这水好不好，还多不多，狐狸掩饰起他的真实危险处境，回答说："下来吧，我的朋友，这水好得使我喝不够，而且多的用不完。

Based on stable and accurate transmission speed of signal,a length vernier method can show 10 ps time interval measurement resolution.

Some whales of our time reach up to 60 feet in length, like the Whale Shark of the Indian Ocean.

在我们这个时代的一些鲸鱼的长度达到60英尺，就如印度洋中的鲸鲨。

The result showed that Ti02 nanowires with a diameter of 20 nm and a length up to several micron only can be synthesized in NH4F/glycol solution with a small amount of water (glycol: H20=39:1), 60V anodic voltage and 2h anodic time. The nanowires originated from the vertical splitting of anodically grown nanotubes.

结果表明，当醇水体积比为39：1时，60V电压下氧化2h，TiO2纳米管顶部的氧化层在缺陷处发生二次击穿溶解，产生自组装的孔核，场助溶解驱动力使纳米管顶部在孔核处沿管轴向垂直劈裂，形成直径20nm、长度可达几微米的TiO2纳米线。

A number of significant conclusions are proposed. For the first time,double arciform strain of the soil nailing is observed in the miscellaneous fill. It is considered as the result that there are two potential slide planes in the miscellaneous fill. The critical anchorage length is analyzed and determined for the first,which is 9 m in this experiment. T...

首次测得并分析了杂填土中土钉的双弓形应变分布形态，指出这是填土边坡中存在2个或以上潜在滑动面的结果；首次测得并分析了土钉临界锚固长度，指出在本试验条件下，其长度约为9 m，并认为临界锚固长度是应变峰值点、零值点和破坏点同时发生转移而形成，锚固类结构均具有此特点。
