First, based on the research of vocality art and vocalization, I discuss how to set up reasonable aesthetics concept on tenor"s voice, then expatiate on the characteristics,of the tenor"s voice in bel canto and the theoretic significance of setting up reasonable sound aesthetics concept. This essay is mainly on the way and key point of constructing tenor" s voice, especially solving the core problem of alt skill. The essay argues that the construction of tenor" s voice is based on the mediant and undertone sections; finding the phonate source, practice step by step, surrounding the point , string and side of the voice; train the students using suitable vowels according to the students with different characteristics ; emphasizing that ten essential words are the golden key to solution of the core problem in the "closing " method.

首先从研究声乐艺术和发声方法的指导思想和出发点着手，探讨了如何建立科学的男高音声音审美观；进而阐述了美声唱法中男高音的声音特点及建立科学审美观的理论指导意义；本文着重提出了构建男高音声音的方法与要领(特别是解决高音技术这一核心问题)，本文认为男高音声音构建先以中、低声区为基础，从找发声点开始，围绕声音的点、线、面逐一训练，同时根据不同特点的学生选择合适的母音进行训练，强调了&关闭&唱法中十字要领是解决核心难点的金钥匙。

Methods 15 SD rats, 8 males and 7 females, were set to receive radiant-heat stimulus at 5 different measure points-right and left footplates, tail root, proximal trichotomous point of the tail and distal trichotomous point of the tail to measure their escape response latencies in a constant ambient temperature (21-23℃) at 3 different time points-9:00, 15:00 and 20:00 in 7 consecutive days.

The cause of hard agglomerate formation and its effect on sinterability were investigated. The water-washed ZrO〓-Y〓O〓 powders were found to be greatly made up of hard agglomerates. The ethanolwashed powders also contained a few of hard agglomerates because of uneffective dehydration. Beside, ethanol volatilizes in advance of water during drying because ethanol has a lower boiling point than water, so steric effects of ethanol won't act. However, nearly no hard agglomerate formed in the azeotropic distilled powders, because of effective dehydration and higher boiling point for n-butanol.

研究指出，水洗工艺所得ZrO〓-Y〓O〓粉末几乎完全由硬团聚组成；乙醇洗涤工艺的脱水效果不是很好，并且由于乙醇的沸点比水低，以致在干燥过程中残留乙醇比水先挥发，乙醇的空间位阻效应不能有效地发挥作用，因此，仍然可以导致产生一定量的硬团聚；而共沸蒸馏工艺的脱水效果最佳，且正丁醇的沸点比水高，干燥时残留正丁醇比水后挥发，从而正丁醇的空间位阻效应可有效地发挥作用，因此避免了在煅烧过程中形成Zr-O-Zr键，即共沸蒸馏粉末中不含硬团聚。

As it invariably happens, history and memory can prove helpful: Leonardo's Vitruvian man is "the measure of all things", while the Renaissance man expands the static point of view of the project anticipating the crucial theme of individual well-being (as Leon Battista Alberti put it in his De re aedificatoria ,"In the choice of the environment it is best to mind that it is welcome by its inhabitants from every point of view").

要设计一项围绕人的实际需求的建筑项目同样意味着创新、价值与激情的构思与应用。创新乃为满足动态参考条件；价值乃为适应社会潜在的经济和结构的变化；激情乃为对于所有参与者以及他们的实际需求的关注。能够证明有效性的永远都是历史与记忆：莱昂纳多·达芬奇的维特鲁威人是&万物的尺度&，同时文艺复兴时期的人发展了项目的静态观点，期望一个非常现代的焦点对象：即个人的康乐。（&在选择环境之时，最好能确保它的方方面面都受到居住者的欢迎&，阿尔贝蒂的《建筑学十书》）。

Result:22 out of 40(55%) primary tumors were detected the point mutations in the coden 12th of k-ras an d n-ras,h-ras.The point mutations of p53 E5 and E7 were found in 16 laryng eal tumors (16/40,40%).

结果：H-ras基因突变9例，突变率为22 。5%(9/40)；K-ras基因突变8例，突变率为20%(8/40)，N-ras基因突变5例，突变率为12.5%(5/40)。p53基因第5外显子突变7例，突变率为17.5%(7/40)；第7外显子突变9例，突变率为22 。5%(9/40)。5例发现有两种基因突变，且均表现为ras基因和p53外显子改变。

Heidegger has taken a sharp turn to language since 1930s, which is not only a subjective event, but also betokens a turn and transition from a traditional linguistic point of view to an existential one and plays a key role in the forming of linguistic point of view in philosophical hermeneutics and deconstructionism.

中文摘要： 20世纪30年代发生的语言转向，不仅是海德格尔本人思想道路上的一个主观转折，同时预示了整个传统语言观向生存论语言观的转向和过渡，对其后的哲学诠释学语言观和解构主义语言观的形成直接产生了决定性影响。
