Historically the arctiid Syntominae was often confused with Zygaenidae, Sesiidae, Euchromiini and Ctenuchini due to the convergent wing shape and colour patterns. According to the phylogenetic hypothesis being more accepted in recent years, the subfamily comprises two tribes, the pan-Old World Syntominiand the Africa-restricted Thyretini.

鹿蛾亚科(Arctiidae： Syntominae)在研究历史上常与斑蛾科、透翅蛾、灯蛾亚科内的丰彩鹿蛾族与蜂蛾族的物种混淆，根据近年较被接受的亲缘关系假说，此亚科包含了分布於泛旧大陆的鹿蛾族以及仅分布在非洲之非洲鹿蛾族。

The paper focuses on the aspectual adverbs in Mandarin Chinese,and proves that the aspectual adverbs in Mandarin Chinese are a kind of PPI,and the distribution of the aspectual adverbs conforms to the hypothesis proposed by Ginnakidou[1],which says that veridical operator license s PPI.

本文通过对汉语中的时态副词的研究，证明了时态副词也是一种正极项，并验证了Ginnakidou[1]所提出的真实性算子对极性敏感项的允准的假说同样适用于解释汉语中的正极项的分布。

Aspectual Interface Hypothesis takes only the internal arguments as the participants to represent the aspectual structure which is regarded as a subpart of the event structure.

体界面假设认为体结构是事件结构的一个子结构，只有内论元参与体结构表达。体结构中体角色网格成员包括两个核心体角色和，外加一个辅助体角色。

Then the listed companies having the corrections of accounting errors in the period from 1999 to 2004 were collected as research sample. Then the incidence which spurred the listed companies adjust errors in time was testified by methods of mean value test and multivariate linear regression. The major empirical results are summarized below: the inspection of The China Securities Regulatory Commission, other supervision outside and income quality correlated positively with it. The effect on profits correlated negatively with it. The hypothesis of the CPA firm change and assets-liabilities ratio didn't correlate with it.

然后选取了1999-2004年披露了会计差错更正的深沪上市公司作为研究样本，运用均值检验和Logistic回归方法考察了上市公司立即更正会计差错的动因，实证研究结果表明：证监会的检查、其他外部监管、收益质量与会计差错的立即更正正相关，损益影响程度与会计差错立即更正负相关，而事务所的变更假设和资产负债率假设未能通过显著性检验。

One may need to entertain the hypothesis that based on the affinity between the network-like structure of comprehension and that of hypermedia products, intensive interaction with the latter might facilitate the construction of rather shallow associationist cognitive networks. Such networks would consist of trivial, frail connections, having no intellectual merit.

我们或许需要思考这一假设：由于意义理解的网络结构与超媒体产品的结构具有相似性，因此，学习者与超媒体产品的深入交互可能会促使学习者建立一种很肤浅的联想性的认知网络，这种网络之中所包含的是一些不甚重要的、虚弱的联系，而没有任何智慧的价值。

Firstly, we hypothesize that the stocks of funds with net outflow will have a higher herding measure when the fund manager is concerned with his reputation risk (Scharfstein and Stein, 1990), and have a lower herding measure when he engages in gaming the incentive scheme derived from the asymmetric performance-flow relation. The results support the reputation-risk hypothesis.

首先，针对前期流量与基金群集指标的关系，本研究推论：如果经理人行为符合声誉风险假说(Scharfstein and Stein， 1990)，则前期净流出基金的群集指标会高於前期净流入基金的群集指标；反之，如果经理人行为符合放手一博假说，则净流出基金的群集指标低於净流入基金的群集指标，实证结果符合声誉风险假说。

Describes general methods of hypothesis testing and optimality properties of tests: Neyman-Pearson theory, likelihood ratio tests, score and Wald tests, uniformly and locally most powerful tests, asymptotic relative efficiency of tests.

假设检验和经验的最有性质： Neyman-Pearson 理论，似然比率估计，score 和 Wald 经验，一致最大功效检验，局部最大功效检验，检验的渐进相对有效性。

Five dimensional asymptotic modal system describing liquid nonlinear resonant sloshing is derived based on Narimanov-Moiseev third order asymptotic hypothesis.

首先利用Narimanov-Moiseev三阶渐近假设关系，推导出描述液体作非线性共振晃动的5维渐近模态系统。

The general infinite dimensional modal system describing liquid nonlinear sloshing is derived first by pressure integral variational principle. After selecting two dominating modes and three secondary modes based on the Narimanov-Moiseev third order asymptotic hypothesis, the infinite dimensional modal system is reduced to a five dimensional asymptotic modal system.

首先通过压力积分变分原理推导出描述液体作非线性晃动的一般形式无穷维模态系统，然后根据 Narimanov-Moiseev三阶渐近假设关系，通过选取二阶主模态和三阶次模态，将无穷维模态系统降为五维渐近模态系统。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
