I won't give another time frame at this point but I can reveal some of the things that will new ME bring: advanced substitutions, freethrows only after shooting fouls, no walkover until at least 2 players are on court for each team, increased influence of experience, improvement in terms of tactics efficiency.

此刻我不会又一次给出时间框架，但是我可以透露些新引擎的内容。换人系统更先进，仅仅投篮犯规后罚球，除非每个队少于2个人在场上才会中止比赛1：20，球员经验的作用加大，战术效能的改进。

The comparison of the genes with white-tailed deer and red deer PrP gene revealed that the nucleotide and its putative amino acid identities were 97.4%-98.2% and 97.7%-98.8%, respectively, it show the PrP genes of ruminant among the same family or different families are all conservative. The comparison of the genes with white-tailed deer and red deer PrP gene revealed there are five base substitutions produced amino acid mutation, e.g.

与同科不同亚科的马鹿和白尾鹿以及不同科的奶牛和绵羊朊蛋白基因序列比较，核苷酸序列和推导氨基酸序列同源性为97.3%～98.2%和97.7%～98.8%，说明朊蛋白基因在同科和不同科的反刍动物间是保守的。

Japonicus used in this experimentation is matemal inheritance.5 Sequence analysis of mitochondrial 16S rRNA and COI gene and molecular phylogeny of four species of sea cucumber500 bp 16S rRNA and 540 bp COI fragment were obtained by PCR method from mitochondrial DNA of four species of sea cucumber, Apostichopus japonicus, Holothuria fuscogilva, Cucumaria frondosa and Mensamaria intercedens. Variable sites, nucleotide diversity, average number of nucleotide differences and average number of nucleotide substitutions per site were calculated to analyze sequence difference, and phylogenetic trees were constructed by the NJ and ME method.

结果显示在来自这5组家系的100个后代中仅检测到母本的单倍型，刺参的线粒体遗传模式表现为典型的母系遗传。5 4种海参16S rRNA和COI基因片段序列比较及系统学研究采用PCR技术对山东荣成、长岛、俄罗斯和日本的刺参，黄乳海参，北大西洋瓜参，二色桌片参的16S rRNA和COI基因片段进行了扩增和测序，分别得到了长度约为500 bp和540 bp的片段。

Such structural complexity is further enhanced by O-acetylation, esterification, lactonization, as well as other forms of substitutions, reflecting significance of carbohydrates in cell recognition.

细胞表面上糖缀合物的糖链经常以多/寡聚体形式存在，并且结构复杂，常常大量表达唾液酸、糖醛酸、硫酸化糖基等酸性糖，并发生O-乙酰化、酯化和内酯化等修饰。

The difference between metaphorical substitutions and metonymic combinations can be seen as a kind of repetition of a deeper and older opposition: between rhetoric and logic.

隐喻替代和转喻连接之间的不同可以被看作是一种更深、更古老的对立的重复：即修辞和逻辑之间的不同。

RESULT ①Two different ITS2 sequences (GenBank accession number: AF416783, AF416784) and D3 sequences (AF416782, AF415594), named as An. minimus A and An. minimus C, were detected in this study. They differed by 5. 8％ in the ITS2 region with 22 fixed nucleotide substitutions and indels, and by 1. 5％ in D3 gene with 5 site mutations. There exists individual variation in the COII gene, but this variation is less than that among other members of Myzomyia Series such as An.

结果 ①分别发现两种不同的ITS2序列（GeneBank登录号：AF416783，AF416784）和D3序列（GeneBank登录号：AF416782，AF425594），与微小按蚊A和C同源。A、C两者ITS2序列22个固定位点存在碱基置换和插入／缺失，序列差异为4.8％；D3基因存在5个固定点突变，突变率1.5％。mtDNA-COII基因存在个体差异，但远小于同系其它成员如乌头按蚊、杰普尔按蚊间的变异。

We choose the effective video as the emotion induce materials, the comedy video was used to induce positive emotion and earthquake tragedy video was used to induce negative emotion. The self-esteem variable includes explicit self-esteem and implicit self-esteem. In my experiments I set four specific situations: succeed, failure, social appraisal and self appraisal, there were also substitutions in achievement condition, such as noncontingent condition.

研究中对情绪状态的引导选取了被证明比较有效的电影视频材料，其中包括喜剧视频剪辑和汶川大地震视频剪辑，用以诱发出正性情绪和负性情绪两种状态；对于自尊变量，本研究从外显自尊和内隐自尊这两个方面来考察；并且在实验一和实验二中主要设置了四种实验情境即成功情境、失败情境、社会评价情境和自我评价情境，而在成就实验情境中又设计了几种重要的子情境。
