錨索測力計介绍

HS-AB系列型振弦式錨索測力計利用特制的应变计作为传感部件，用于长期监测预应力锚索对岩体或建筑物施加压力的大小，无需温度修正，测值准确、性能稳定。使用时，安装在岩石边坡或混凝土建筑物的预应力锚索上。振弦式錨索測力計有二弦、三弦、四弦和六弦。

錨索測力計工作原理

1、荷載使鋼筒産生軸向變形，應變計同步變形，振弦産生應力變化，從而改變振弦的振動頻率；

2、電磁線圈激振振弦並測量其振動頻率；

3、頻率信號經電纜傳輸至讀數裝置，即可測出引起受力鋼筒變形的應變量；

4、代入标定系数可算出錨索測力計所感受到的荷载值。

"If that's the case," Frank retorted, "you'd better wrap your list around a bushel of money. It'll take a good deal to buy the whole of those two countries." Fred wanted ever so much to send home a goldfish with a very wide and beautiful tail. The fish didn't seem to be much unlike a common goldfish, except in the tail, which was triple, and looked like a piece of lace. As it swam around in the water, especially when the sun was shining on the globe, its tail seemed to have nearly as many colors as the rainbow, and both the boys were of opinion that no more beautiful fish was ever seen. But the proposal to send it to America was rather dampened by the statement of the Doctor that the experiment had been tried several times, and only succeeded in a very few instances. Almost all the fish died on the voyage over the Pacific; and even when they lived through that part of the trip, the overland journey from San Francisco to the Atlantic coast generally proved too much for them. The Japanese name for this fish is kin-giyo, and a pair of them may be bought for ten cents. It is said that a thousand dollars were offered for the first one that ever reached New York alive, which is a large advance on the price in Yokohama. JAPANESE ARTIST CHASING ON COPPER. JAPANESE ARTIST CHASING ON COPPER. Nara is about thirty miles from Osaka, and is famous for some ancient temples and fine groves of trees. The park containing the latter is quite extensive, and supports a considerable number of deer, so tame that they will feed from the hand of a stranger. As they are the stock sights of the place, there are plenty of opportunities to spend a few pennies for cakes to be given to the deer. The cakes are sold by some old women, who call the pets from the shelter of the trees, and bring them bounding to your side. The trees in the park are very old, and among the finest in Japan. There are few lovelier spots in the country than this; and as our friends reclined on the veranda of the little hotel to which John had led the way, and looked upon the smiling valley that spread before them, they pronounced the picture one of the prettiest they had ever seen. A document purporting to be Aristotle’s will has been preserved by Diogenes Laertius, and although some objections to its authenticity have been raised by Sir A. Grant, they have, in our opinion, been successfully rebutted by Zeller.180 The philosopher’s testamentary dispositions give one more proof of his thoughtful consideration for the welfare of those about him, and his devotion to the memory of departed friends. Careful provision is made for the guardianship of his youthful children, and for the comfort of his second wife, Herpyllis, who, he says, had ‘been good to’ him. Certain slaves, specified by name, are to be emancipated, and to receive legacies. None of the young slaves who waited on him are to be sold, and on growing up they are to be set free ‘if they deserve it.’ The bones of his first wife, Pythias, are, as she herself desired, to be laid by his. Monuments are to be erected in memory of his mother, and of certain friends, particularly Proxenus, who had been Aristotle’s guardian, and his family. It was melancholy to return under the gloomy, spreading banyans, through the dimly-lighted suburbs, where the people were still at work and selling their wares; and the dungeon, the dead stones, the guns now for ever silenced and pointed at vacancy, were lost in blue darkness. As they swung in a banked turn to circle over the Sound, the green disappeared and its place was taken, as it seemed, by red. Then they walked up to the corral together. Kirby introduced him to his two partners, Englishmen also, and finished nailing up the boards of a box stall which a stallion had kicked down in the night. After that he threw down his hammer, took two big nails from his mouth, and sat upon the tongue of a wagon to talk long and earnestly, after the manner of men who have shared a regretted past. Defeated in this object, the Patriots united all their force to embroil us with Spain. There were many causes in our commercial relations with Spain which led to violent discontent amongst our merchants. They found the trade with the Spanish settlements in America exceedingly profitable, but they had no right, beyond a very limited extent, to trade there. The Spaniards, though they winked at many encroachments, repressed others which exceeded these with considerable vigour. Their Coastguard insisted on boarding and searching our vessels which intruded into their waters, to discover whether they were bringing merchandise or were prepared to carry away colonial produce. By the treaty of 1670 Spain had recognised the British colonies in North America, and England had agreed that her ships should not enter the ports of the Spanish colonies except from stress of weather, or with an especial licence from the Spanish Government to trade. By the treaty of 1729 we had agreed to the old regulations regarding trading to the Spanish Main, namely, that we should have the Assiento, or right of supplying these colonies with slaves, and that, besides this, we should only send one ship annually to the Spanish West Indies and South America. As fast as that authorised ship discharged its cargo in a Spanish port, she received fresh supplies of goods over her larboard side from other vessels which had followed in her wake, and thus poured unlimited quantities of English goods into the place. Other English traders did not approach too near the Spanish coasts, but were met in certain latitudes by South American smugglers, who there received their goods and carried them into port. In short, such a system of contraband trade was carried on in these waters by our merchants, that English goods in abundance found their way all over the Spanish American regions, and the great annual fair for goods imported from or by Spain dwindled into insignificance. "Yes," he said huskily—"it is." "What time?—and I'll promise father shall be here to see you." HoME 亚洲偷拍自拍在线电影 ENTER NUMBET 00104h5fim.com.cn
