The purpose of this reiewis to present a structured assessment of the anti-tumour and cytotoxic properties of 150 marine natural products, many of which are noel compounds that belong to dierse structural classes, including polyketides, terpenes, steroids and peptides.

本综述旨在对大约150个海洋天然产物的抗肿瘤及细胞毒活性进行化学结构上的分析，其中许多化合物属于不同的结构类型，包括聚酮化合物、帖类、甾体以及多肽。

However, more and more studiespresent that the local pressure fluctuations in the separated and reattached region of bluff body are found tobe non-Gaussian. The Gaussian assumption will underestimate the wind load of cladding and cause thecladding to unsafety. It is a general way to estimate peak pressure by a fixed peak factor.

然而，有越来越多的研究表明，钝体绕流的分离和流动再附着区域的风压呈现出强烈的非高斯分布的特性，按照高斯分布进行峰值风压的估计将可能低估作用于围护结构上的风荷载而造成结构的不安全性。

The three markers are further examined in terms of their collocational patterns, both grammatical and lexical. Significant differences are found in the collocation of adverbial adjuncts.

接著，我们进一步研究这三个标记的句法及词汇搭配结构，结果发现在副词的搭配结构上三者有显著的差异。

The purpose of this paper is to extract the coupling matrix of generalized chebyshev filter, model the four-port rectangular junctions, multiple-stepped rectangular waveguide bend and T-septum rectangular waveguide junction by full-wave methods and design generalized chebyshev filters and diplexers. The main works are as follows: 1. Systematically research on the theory of generalized chebyshev filters The generalized chebyshev filters are based on the all-coupled model.
