近日，“阿里员工得白血病身故，生前租住自如房被指甲醛超标”的新闻引起人们对房屋甲醛檢測的关注.各种便携式家用甲醛檢測仪也成了不少人竞相购买的热销品.网络销售甲醛檢測仪准确吗？

在各大电商平台上输入“甲醛檢測仪”，都能搜索到几百件不同商品.这些检测仪售价从几十元到1000元不等，差距悬殊.这些检测仪商家都宣称自己的产品能够“精准测量甲醛含量”，有的标注了该产品对于甲醛的检测范围，有的还声称可检测苯、PM2.5、挥发性有机物等，“春夏测甲醛，秋冬测雾霾”，将“一机多用”作为卖点进行宣传.

檢測儀檢測室內甲醛顯示數值爲零
近日，有媒体从网上按照不同的价位购买了7款甲醛檢測仪进行试验.结果发现在同一时间、同一地点，这7款检测仪的检测结果中没有任何两款数值是相同或者非常接近的.不仅检测仪显示的数字不稳定，甚至出现部分检测仪这一次检测显示为零，下一次检测却超标的情况.也就是说，这些检测仪无法提供精确的甲醛数值，通过便携式家用甲醛檢測仪难以达到预想的效果.
甲醛檢測仪被夸大可以检测多种污染源

“网购的便携式甲醛檢測仪质量参差不齐，测出的结果基本上不靠谱.”国家室内车内环境及环保产品质量监督检验中心建议消费者不要盲目购买网上这种便携式的检测仪.为了家人的安全建议找正规的甲醛檢測公司进行室内检测.更多甲醛檢測小知识請关注本品牌除醛网.

Miss Harper "knocked me down," as we boys used to say, to Charlotte Oliver; "Charlotte, my dear, you already know Mr. Smith, I believe?" "Well, one hears some queer things," the novelist said at length. "I've been fascinated with that corner house for years. As I told you before, I built up a romance round it. Some day I mean to take the papers out of my pigeonhole and work it up." "I am coming to the point fast enough. You know Lefevre of Lyons?" We must, however, observe that, underlying all these poetical imaginations, there is a deeper and wider law of human nature to which they unconsciously bear witness—the intimate connexion of religious mysticism with the passion of love. By this we do not mean the constant interference of the one with the other, whether for the purpose of stimulation, as with the naturalistic religions, or for the purpose of restraint, as with the ethical religions; but we mean that they seem to divide between them a common fund of nervous energy, so that sometimes their manifestations are inextricably confounded, as in certain debased forms of modern Christianity; sometimes they utterly exclude one another; and sometimes, which is the most frequent case of any, the one is transformed into the other, their substantial identity and continuity being indicated very frankly by their use of the same language, the same ritual, and the same aesthetic decoration. And this will show how the decay of religious belief may be accompanied by an outbreak of moral licence, without our being obliged to draw the inference that passion can only be held in check by irrational beliefs, or by organisations whose supremacy is fatal to industrial, political, and intellectual progress. For, if our view of the case be correct, the passion was not really restrained, but only turned in a different direction, and frequently nourished into hysterical excess; so that, with the inevitable decay of theology, it returns to its old haunts, bringing with it seven devils worse than the first. After the220 Crusades came the Courts of Love; after the Dominican and Franciscan movements, the Renaissance; after Puritanism, the Restoration; after Jesuitism, the Regency. Nor is this all. The passion of which we are speaking, when abnormally developed and unbalanced by severe intellectual exercise, is habitually accompanied by delirious jealousy, by cruelty, and by deceit. On taking the form of religion, the influence of its evil associates immediately becomes manifest in the suppression of alien creeds, in the tortures inflicted on their adherents, and in the maxim that no faith need be kept with a heretic. Persecution has been excused on the ground that any means were justifiable for the purpose of saving souls from eternal torment. But how came it to be believed that such a consequence was involved in a mere error of judgment? The faith did not create the intolerance, but the intolerance created the faith, and so gave an idealised expression to the jealous fury accompanying a passion which no spiritual alchemy can purify from its original affinities. It is not by turning this most terrible instinct towards a supernatural object that we should combat it, but by developing the active and masculine in preference to the emotional and feminine side of our nervous organisation.136 Mr. Trustee, I'll know just how an orphan asylum ought to be run. One of the servants of the place, sitting in the shade of the arcade, was painting, after a strange method. He sprinkled powdered colour on the surface of some water in a tub, outlining the colour with black; then, with a feather, he massed and arranged the colours, taking some off and replacing it in infinitesimal quantities. Finally the result was a representation of Siva and Ourasi, robed in blue and violet, against a background of crude red. When they were quite finished he jerked the bowl, giving the figures a curtseying motion, and stood a little way off to contemplate the general effect;[Pg 158] and then, quite satisfied, stirred the whole thing up and began again, the same picture, with the same precise care. She drew her horse down to a gallop, and the jar of the changed gait made her moan. There was no haste now. Her own men had come upon the desperadoes and there was a quick volley. And ahead, riding fast toward her from the top of a little rise, was a man on a white horse—her husband, she knew. These things did not pass without remark by the Opposition. Pulteney and Bolingbroke discussed them with much vigour and acrimony in The Craftsman. It was asserted in the House that the public burthens had increased instead of diminished since 1716; but Walpole contended that there had been a reduction of debt to the amount of two million five hundred thousand pounds; and his statement was supported by a large majority, and it was laid before the king. The Opposition then demanded an explanation of the expenditure of two hundred and fifty thousand pounds for secret service money. It was well understood that Walpole had used the greater part of it in buying up that triumphant majority which enabled him to carry the most[59] obnoxious measures. The demands of the Opposition were so vehement, and the abuse was so glaring, that even Walpole was embarrassed how to get rid of the question. He could only recur to the old plea, that the money had been spent on services highly advantageous to the State, but which could not properly be made public. Suddenly events lifted him out of his difficulty. News arrived that the King of Spain, who declined to ratify the preliminaries of peace entered into at Vienna, on hearing of the death of George I., hoping for a revolution, had now given way, and had issued what was called the Act of Pardo, ratifying the preliminaries, and referring all remaining difficulties to be settled at a congress to be held at Soissons. [See larger version] Her merry laugh filled the room, and rang even into the dark cells inside. Shorty shambled to his feet, pulled off his hat, and stood with downcast eyes and burning face. He had never encountered anything so beautiful and so terrifying. "I'm so glad you've come," said the Sheriff. "Things is beginnin' to look very ugly outside. They've got the whole country stirred up, and men are coming in on every road. You take command, Sergeant Klegg. I've bin waitin' for you, so's I could drive over to the station and send a dispatch to the Governor. The station's about a mile from here, but I'll be back as soon as my horse'll bring me. I didn't want to send the dispatch till I was sure there was need of it, for I don't want to bring soldiers here for nothin'." "Now, great Scott, what's up?" said Si angrily, as he quickly surveyed the surrounding country. He saw that they were not attacked, and then clambered to the top of the car, where he noticed little wreaths of powder-smoke lingering around the squad in which were Jim Humphreys, little Pete Skidmore and Wes. Brown. CHAPTER XIX. THE FIRST SCRAPE Reuben crept out of his thorn cavern and looked down the slope. At the bottom by Socknersh one or two lanterns moved through the dusk. He stiffly threw up his arm and tried to shout. His throat felt cramped and swollen, and it was not till after one or two attempts that a sound pitifully like a bleat came out of it. A voice answered him from the hollow, and then he saw that they were carrying something. He limped painfully down to them. Richard, Boorman, and Handshut carried a hurdle between them, and on the hurdle lay a draggled boy, whose clenched hand clutched a tuft of earth and grass as a victim might clutch a handful of his murderer's hair. "Retire, kerns!" said De Boteler, glancing with anger at Oakley and the galleyman, "and settle your vile feuds as ye may. Disturb not this noble presence longer."
