逐渐消失的

Morphological conversion from spiralto coccoid forms occurred when HP was cultured with selenium and most of coccoid forms had fragmentary flagella and pilus; the effection of selenium to activity of urease, catalase, alkaline phosphatase is not exist or not evidence; selenium enable pET32a-vacA-E.coli BL21 which can express VacA produce yellow lipochrome, and the color become deeper with increasing of concentration of selenium; selenium can decrease expression of recombined VacA by restrain the growth of pET32a-vacA-E.coli,but can not influence activity and gene sequence of VacA; selenium can enhance the suppression effect of recombined VacA for gastric cancer cell, depress the index of cell multiplication and the forming rate of colony, decrease the number of cell in S period, increase total of cell in G period; After purified, the recombined VacA can be identified by VacA antibody.

体外实验结果表明：一定浓度的硒作用HP后，HP菌落数量随着硒浓度的增加而减少，菌落颜色由灰白色变为砖红色，溶血现象随硒浓度的增加和作用时间的延长而逐渐消失，HP的形态由弯曲形变为球形或椭圆形，鞭毛及菌毛出现脱落现象；硒对尿素酶、过氧化氢酶、碱性磷酸酶活性无影响或影响不明显；一定浓度的硒能使表达VacA的pET32a-vacA-E.coli BL21工程菌产生脂溶性砖红色色素，颜色随硒浓度增加而加深；一定浓度的硒通过抑制pET32a-vacA-E.coli BL21工程菌的生长，减少重组VacA表达量，但不影响其空泡毒活性及编码基因序列；纯化后的VacA重组蛋白可被VacA抗体识别，具有良好的抗原性。

It is easy enough to say that man is immortal because he will endure: that when the last ding-dong of doom has clanged and faded from the last worthless rock hanging tideless in the last red and dying evening, that even then there will still be one more sound: that of his puny inexhaustible voice, still talking.

我拒绝接受人类末日的说法，因为人是不朽的，他的延续是永远不断的——即使当那末日的丧钟敲响，并从那最后的夕阳将坠的岩石上逐渐消失之时，世界上还会留下一种声音，即人类那种微弱的却永不衰竭的声音，在绵绵不绝。

When we put the fish emblazonment into the emblematic area of the whole China, we can find that the extreme worship to the genital organs and the strong sorcery meaning have disappeared gradually. However, its emblematic meaning to life has been converted into a unconscious idea that hides in our national culture, and it results in a deep effect on our national art and the aesthetic pursuit.

当我们把鱼形纹饰放到整个中国的装饰领域，我们就会发现那种对生殖如痴如醉的崇拜，那种浓烈的巫术意义已逐渐消失，然而，它关于生命的象征意义却转化为一种无意识的观念形态潜藏在我们民族的文化之中，并对我们民族艺术和审美追求产生了深远的影响。

It had become evident that the simple, familiar, and unceremonious ways which had marked the Franciscan movement at its beginning were gradually disappearing, and that the heroic poverty practiced by Francis and his companions at the outset became less easy as the friars with amazing rapidity increased in number.

它已成为明显的是，简单，熟悉，和粗鲁的方式这标志著方济各运动在其开始逐渐消失，而且贫穷的英勇实行弗朗西斯和他的同伴在开始变得不那麼容易的修士具有惊人的速度增加在号码。

However, DPP nanoparticles were found to present multiple emission from pyrene at 385 nm, pyrazoline at 465 nm and an intermolecular pyrazoline-pyrene charge-transfer state at 570 nm, and each of them possesses individual optical channel.

在粒径确定时，用一确定波长激发时，发射光谱中不同发射的最大强度直接决定于对应激发光谱在该波长下的强度。另一方面，超微粒粒径的大小同样影响着三个部分的相对强度。随着粒径的增大，吡唑啉环-芘环之间电荷转移态570 nm的荧光发射逐渐消失。

It is easy enough to say that man is immortal simply because he will endure: that when the last ding-dong of doom has clanged and faded from the last worthless rock hanging tideless in the last red and dying evening, that even then there will still be one more sound: that of his puny inexhaustible voice, still talking.

我拒绝受人类末日的说法，因为人是不朽的，他的延续是永远不断的……即使当那末日的丧钟敲响，并从那最后的夕阳将坠的岩石上逐渐消失之时，世界上还会留下一种声音，即人类那种微弱的却永不衰竭的声音，在绵绵不绝。

然而当这种技术创新体系赖以形成与发挥作用的基础逐渐消失，技术创新模式必须作出根本性的调整时，制度的转型则成为必然的发展趋势。20世纪90年代以来的日本正处在制度转型的重要时期。

Focusing on the 168 entries of annotation of "hui", this article has the exhaustive studies on semantic system, and induces 11 sememes. Among these sememes, some disappeared gradually with the developing of the meaning of the word, some became morphemes which exist in contemporary Chinese disyllabic words.

本文选取其中有代表性的&回&字，对它的168条训释作穷尽性的语义系统研究，归纳出11个义项，这些义项有的在词义发展过程中逐渐消失，有的成为语素构成现代汉语的双音词。

李景湖的《雪人》是一件特定现场的装置作品。他以一种轻松的心态，用成卷的卫生纸在空间里堆积起一座硕大的&雪人&，这个&雪人&将在一个月的时间里随着货品的不断售出而在人们的视野中逐渐消失。

In "new-reality-fiction", people lost their controlling power to the history and became suspicious of their own subjects, and they, too, lost their selfconsciousness as the rebels, a category of characters aroused in the new-period of Chinese history.

同时，新时期以来的人作为反叛形象的自我主体意识在&新写实小说&中也逐渐消失，现实物质的困窘与日常生活的磨损成为自我主体丧失的辩辞，人在现实日常生活中变得无所作为。
