Polymetron 9610sc 在线硅表

水樣中的二氧化矽與钼酸鹽離子在酸性條件下發生反應，生成矽钼酸絡合物。添加草酸來破壞磷酸鹽絡合物，並加入硫酸亞鐵铵試劑使黃色的矽钼酸變成藍色。于波長815nm處進行測定，檢測樣品顔色的變化。由于顔色的深淺與二氧化矽的濃度成比例關系，所以利用比色分析法可計算並得出二氧化矽的濃度值。

The steamer descended the Woosung River to its intersection with the Yang-tse-kiang, and then began the ascent of the latter. The great stream was so broad that it seemed more like a bay than a river. This condition continued for a hundred and fifty miles, when the bay narrowed to a river, and the far-famed Silver Island came in sight. It stands in mid-stream, a steep hill of rock, about three hundred feet high, crowned with a pagoda, and covered from base to summit with trees and bushes and rich grass. At first it might be taken for an uninhabited spot, but as the boat approaches you can see that there are numerous summer-houses and other habitations peeping out from the verdure. A little beyond the island there is a city which straggles over the hills, and is backed by a range of mountains that make a sharp outline against the sky. This is Chin-kiang, the first stopping-place of the steamer as she proceeds from Shanghai to Han-kow. She was to remain several hours, and our friends embraced the opportunity to take a stroll on shore. Here is Frank's account of the expedition: The unhappy man bowed his head trembling,247 and with dull resignation he left the office, strongly escorted. Three youths, thrilled by the prospect of a mysterious adventure, and a war pilot, intent on a friendly service, discussed plans for protecting the Everdail Emeralds. Captain Parks, however, agreed with Mr. Everdail, who trusted him absolutely—if Sandy did not—that it would be wise not to give any person who had been on the yacht during its crossing any chance to get away. “It’s the hydroplane, then!” Dick decided. “It’s coming from the water-dock inside the boathouse, now—there it is. Hey! You! Stop!” "Well," drawled Cairness again,—he had learned the value of the word in playing the Yankee game of bluff,—"with those about the beef contract and those about the Kirby massacre, also a few I gathered around San Carlos (you may not be aware that I have been about that reservation off and on for ten years), with those facts I could put you in the penitentiary, perhaps, even with an Arizona jury; but at any rate I could get you tarred and feathered or lynched in about a day. Or failing all those, I could shoot you myself.[Pg 260] And a jury would acquit me, you know, if any one were ever to take the trouble to bring it before one, which is doubtful, I think." Then he heard little Abel Waite say: He had anxiously sought the entire length of the camp for something of that kind. He had visited all the sutlers, and canvassed the scanty stocks in the few stores in Chattanooga. He had bought the sole remaining can of tomatoes at a price which would have almost bought the field in which the tomatoes were raised, and he had turned over the remnant lots of herring, cheese, etc., he found at the sutler's, with despair at imagining any sort of way in which they could be worked up to become appetizing and assimilative to Si's stomach. "Johnny...." And years of despair and remorse been your fate, "What ails you, man?" inquired Black Jack—"you look the worse for your long fast—here, drink," handing him a full pitcher. It was in vain that the baroness cast on him a glance that said he had adopted a wrong course—it was in vain that his own better judgment whispered, that he ought to leave the management of the affair in the hands of her who could smile and sooth, when she had an object to attain, without the least violence to her feelings: his anger was set in motion, and it would have required an influence much stronger than the Lady Isabella's to have calmed its ebullition. Although De Boteler spoke so rudely, yet Turner was pleased that it was he whom he had now to contend with; and, looking doggedly at the angry baron, he said, "And if you had never known me," said Holgrave, starting up and grasping Turner's hand, "you need not have changed your name: but you are an honest man, let you be called what you may—and Stephen Holgrave will never forget what you have done for him and his."
