While we were in this condition, the men yet labouring the oar to bring the boat near the shore, we could see then our boat mounting the waves, we were able to see the shore, a great many people running along the shore to assist us when we should come near, but we made but slow way towards the shore, nor were we able to reach the shore, till being past the light-house at Winterton, the shore falls off to the westward towards Cromer, and so the land broke off a little the violence of the wind: Here we got in, and though not without much difficulty got all safe on shore and walked afterwards on foot to Yarmouth, where, as unfortunate men, we were used with great humanity as well by the magistrates of the town, who assigned us good quarters, as by particular merchants and owners of ships, and had money given us sufficient to carry us either to London or back to Hull, as we thought fit.

尽管我们处在这种情况，水手们还是奋力把小艇向海岸划去。我们能够看见，当小艇随浪尖升起时，我们已能看到海岸了，还看见有许多人在岸边跑动，等我们小艇靠岸时救助我们。但小艇前进的速度很慢，而且怎么也无法靠岸。最后，我们小艇竟飘过了温特顿岬角的灯塔。海岸已经处在克罗默西边的位置。这样，陆地削弱了一点风势，在这里我们全体安全上了岸，虽然也是克服了许多困难。上岸后我们步行至大雅茅斯。我们这些不幸者照例受到了这个城镇的社会贤达们非常人道的接待；他们通过一些商人和船主妥善安置我们住宿，还为我们筹足了旅费，以便按我们的意愿送我们去伦敦，或送我们回赫尔市。

While we were in this Condition, the Men yet labouring the Oar to bring the Boat near the Shore, we could see, hen our Boat mounting the Waves, we were able to see the Shore, a great many People running along the Shore to assist us when we should come near, but we made but slow way towards the Shore, nor were we able to reach the Shore, till being past the Light-House at Winterton, the Shore falls off to the Westward towards Cromer, and so the Land broke off a little the Violence of the Wind: Here we got in, and tho' not without much Difficulty got all safe on Shore and walk'd afterwards on Foot to Yarmouth, where, as unfortunate Men, we were used with great Humanity as well by the Magistrates of the Town, who assign'd us good Quarters, as by particular Merchants and Owners of Ships, and had Money given us sufficient to carry us either to London or back to Hull, as we thought fit.

尽管我们处境危难，水手们还是奋力向岸边划去。当小艇被冲上浪尖时，我们已能看到海岸了，并见到岸上有许多人奔来奔去，想等我们小艇靠岸时救助我们。但小艇前进速度极慢，而且怎么也靠不了岸。最后，我们竟划过了温特顿灯塔。海岸由此向西凹进，并向克罗默延伸。这样，陆地挡住了一点风势，我们终于费了九牛二虎之力靠了岸。全体安全上岸后，即步行至雅茅斯。我们这些受难的人受到了当地官员、富商和船主们的热情款待；他们妥善安置我们住宿，还为我们筹足了旅费。我们可以按自己的意愿或去伦敦，或回赫尔。

On mountainous sites, grade Ⅰ or Ⅱ stands including land below the crown of the secondary broadleaf forest and the Chinese-fir plantation or east-facing, shady dry land could be considered for the plantation. The transmittance of crown in the areas should be 55%~60%. One-year-old high quality seedlings above 25 cm tall and 0.25 cm in diameter near the ground-level should be used. For high-yield, field cultivation, shading facility should be considered and seedlings of taller than 15 cm and greater than 0.15 cm in diameter near the ground should be applied. The appropriate density and sunlight transmittance ought to be 30 cm×30 cm and 50%, respectively.

Results revealed that the large side insulation of the stator bar in slot is available for ultrasonic pulse-echo testing; Coupling transducer on the surface of a practical stator bar could minimize the influence on the measurements of velocity, contributing no destructivity of the ultrasonic testing for stator insulation; The simultaneity of same velocity and higher attenuation can be used to detect insulation delamination from conductors; Compared with the wide sides of the bars in slot, the short sides of the bars near the exit from slot and the end bars had a same velocity and a higher attenuation; The velocity might be exactly measured on the shot sides of the bars near the exit from slot and the end bars, while the attenuation might not, which were examined though filed tests; V min decreased greatly and V av decreased slightly with the service time of the bars.

在实验室对线棒多种结构处的主绝缘和不同运行年数(未老化、16、18 和23年)线棒的主绝缘进行了低频超声反射法检测试验，并进行了现场试验，发现(参见 Hao et al， IEEE DEI， to be published)，槽部线棒的宽面绝缘不受换位绝缘的影响，比窄面绝缘更适合超声测量；线棒表面平滑的半导体层减小了耦合剂对超声测量的影响，实现了无损性；波速不变而声衰减减小可以检测线棒出现绝缘与导体脱壳缺陷；出槽口和端部线棒的窄面绝缘与槽部线棒的宽面绝缘相比，声衰减大而波速一致；现场试验验证了波速不受绝缘结构和现场测试条件的影响，而声衰减受以上因素影响很大(参见 Hao et al，中国电机工程学报， Vol.23 No.4)； V min 随运行年数明显减小， V av 随运行年数慢慢越小。

Then base on theweak interference of cable displacement and near influence of hanger tension theories, deducing thesimplified computation method in construction stage. Accouding to the result from optimization, contractwith the result that from using the finite element sofeware ANSYS, we consider the geometric nonlinearand so on. Through the example proving, deduce the simplified optimization method which iseffectiveness, and disproof the weak interference of cable displacement and near influence of hangertension theories is illogicality.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
