Compared with classical cytotoxic T lymphocytes , NK cells are superior in the following aspects: NK cells are among the first cell types to be activated after intracellular pathogen stimuli, the activity of NK cells peaked between 1 to 3 days, retained during the first 7-10 days, and the T cells response emerged only after 7 days when the NK cell responses begin to decline; though comprising of only 10％-15％ of peripheral lymphocytes, NK cells mobilize most of the cell populations in a strong and high level response to different invasions, and act as key factors at early defense before a specific immune response could mount, while only certain clones were involved in T cell response; NK cells kill virus-infected or malignant transformed cells without pre-sensitization and without restriction by major histocompatibility antigen, which is usually a mechanism of immune escape to T cell recognition by virus-infected or tumor cells, thus NK cell in complementary with T cells play crucial roles in tumor and virus eradication.

NK细胞以其强大的细胞毒活性为特征，与细胞毒性T细胞相比，NK细胞具有如下特点：NK细胞虽然只占外周血淋巴细胞的10-15％，但是对刺激性因素产生应答的过程十分迅速，一次可以调动大多数细胞共同参与，而不是几个克隆的活化，免疫应答的强度高；病毒感染或恶性转化细胞的一个主要特征是细胞表达的MHCⅠ类分子下降或消失，并借助这一机制逃避特异性T细胞应答的识别，NK细胞介导的杀伤活性无需抗原刺激，不受MHCⅠ分子表达的限制，从而与T细胞应答互为补充发挥免疫防御的功能；NK细胞的免疫活性可以被多种细胞因子上调，其中IFNα，IL-2，IL-12，IL-15和IL-18具备更强的作用；NK细胞具有强大的细胞因子分泌功能，对于启动T细胞特异性应答必不可少。

As to the new theories about the kind of thing sacraments are, the canons[21] condemn those who say: that there are more or less than seven sacraments instituted by Christ our Lord--baptism, confirmation, the Eucharist, penance, extreme unction, order, marriage--or that any one of these is not truly a sacrament in the full sense of the word; that these sacraments only differ from the sacraments of the Jewish dispensation as one ritual from another; that the sacraments are not a necessity of salvation, but that through faith alone, and without the sacraments at all, man can obtain from God the grace of Justification; that the sacraments were instituted for the purpose of nourishing only faith; that the sacraments do not contain and confer the grace which they signify--as though they were but outward signs of the grace or justice received through faith, badges of Christian profession that mark off the believer from the infidel; that the sacraments do not themselves confer grace by the very activity of the sacrament, but that only faith in the divine promises is sufficient to obtain grace; that all Christians have the power to administer all the sacraments; that any pastor of the Church can change the received and approved rites used by the Church in the solemn administration of the sacraments.

至於新的理论对这种事圣礼是，该炮[ 21 ]谴责那些谁说：有多於或少於7圣礼所建立基督我们的上帝-洗礼，确认，圣体，忏悔，临终，秩序，婚姻-或任何其中之一是没有一个真正的圣礼在充分意义上的；这些圣礼只有不同於圣礼犹太分配作为一个仪式从另一个；的圣礼没有必要救赎，但仅通过信仰，并没有在所有的事，男人可以得到上帝的恩典的理由；的圣礼被提起，目的是滋养只有信仰；的圣礼不包含并赋予它的恩典他们象徵-就像他们的迹象，但外向的恩典或司法收到通过信仰，徽章的基督教界人士说，马克从信徒从异教徒；的圣礼本身并不赋予宽限期的非常活动圣礼（当然opere operato ），但只有信仰的神圣承诺足以获得宽限期；所有基督教徒有权力来管理所有的圣礼；，任何教会牧师可以改变收到并批准使用的仪式在庄严的教堂行政管理圣礼。

Disappointing explanations were given to interrogators by Taiwanese officials stated that budgetaryrestrictions or invisible importance were often the excuses.Every January, Madrid hosts an international tourism exhibition, the "FERIA INTERNATIONAL DE TURISMO", which is a major event of the European travel industry. The Madrid World Trade Center houses ten large-scale exhibition halls for this weeklong event that is attended from five continentsand 170 countries compose total of 100,000 participants. An event that play a decisive role in tourism, Taiwan's exhibition booth had failed to display the ambitions of promoting Taiwan and hospitality in comparison with other Asia countries, such as China, Thailand, and Macao. Apparently, we showed ourlack of preparation and desire to publicize Taiwan's tourism. The booth only provided a few explanatory flyers and pamphlets; most of them are in English only. The Information Division of Taiwan's representative office in Madrid (the "Oficina Económica y Cultural de Taipei") also gave away some souvenirs.Unfortunately, none of Taiwanese tourist professionals participated in the FITUR. A local ticket sales agent of China Airlines in Madrid was the only representative among other major airlines from Taiwan.

每年一月份在马德里固定举行的「国际旅游展」，可以说是欧洲旅游业的一大年度盛事，来自五大洲一百七十国的旅游主管单位以及相关业者，把拥有十个大型展览馆的马德里世贸展览场塞满，一个展期下来参观的专业人士总是有十万人；然而，台湾的摊位相较於同样位於亚洲馆的中国、泰国、澳门等观光事业的竞争对象，明显地看出缺乏准备和推广的企图心；除了准备些许解说折页，以及驻西代表处新闻组提供的一些文宣品赠送以外，看不到任何台湾旅行业者参与或推出任何产品，台湾两大航空业者也只有华航由马德里票务代理业者出面虚幌两天。

Many scholars have studied these respects and given many important results, for example, the Hupperts famous theorem, namely, a finite group G is supersolvable if and only if every maximal subgroup of G has prime index; a finite group G is nilpotent if and only if every maximal subgroup of G is normal in G; a finite group G is solvable if and only if every maximal subgroup of G is c-normal in G (See it in [70]); etc.

很多学者都在这些方面进行了研究，得到了很多重要的结果，如：著名的Huppert定理，即有限群为超可解当且仅当它的所有极大子群的指数为素数；有限群为幂零当且仅当每个极大子群都正规；有限群为可解当且仅当它的极大子群均c-正规(见[70])；等等。

Thus there is no substitute for the double genitive in a sentence such as That's the only friend of yours that I've ever met, since sentences such as That's your only friend that I've ever met and That's your only friend, whom I've ever met are obviously impossible.
