Five advertisements made to the world by the Imperial Trumpet: 1 it transfers imperialist strategic thinking, national economy and military actions to the world; it transfers the American human right culture and living styles to the intellectuals over the world; 3 it transfers the imperialist market/corporate system and political system to the rights activists and elites of the world; 4 it exports culture and transfers American image to the young of the world so as to Americanize them; 5 it tells the world civilian equal social environment and successful stories.

After getting these four line-of-sight vectors, we inverse these data in special observation coordinate based on space analytical geometry, then we can get the vector that has three components on every coordinate, this vector will be treated as the total wind profile in the three-dimensional observation field, the result of this four-point method can basically reflect all the spatial and temporal variation of the atmospheric wind.

在得到视线方向风速矢量后，从选定的三维观测坐标系对这四个矢量进行空间解析几何的运算，可得到观测坐标系的各坐标轴上四个测量矢量的各坐标分量的标量和。从而以这个在三个坐标轴上都有分量的矢量作为在观测视场内的总的风场的风速矢量。

本研究筛选到四类对稻瘟病菌附着胞形成具有不同抑制机制的拮抗细菌，并对h23菌株的抗菌活性进行详细分析；同时还测定了毛壳菌对稻瘟病菌附着胞的抑制作用。

This article analyzes preliminary conditions for establishment of four common circumventions, say, Importing Country Assembly, Third Country Assembly, Minor Alteration, Later-Developed Merchandise, through research on anti-circumvention cases about bikes, candles, carbon steel plate and so on.

通过欧盟对华自行车反规避案、美国对华石蜡蜡烛反规避案、美国对加拿大定尺碳素钢板反规避案等案例的研究，分析欧盟和美国对进口国境内组装、第三国组装、轻微改变产品、后期开发产品四种常见规避行为的认定条件，比较欧盟和美国规避认定的异同，在此基础上提出了对完善我国反倾销规避制度的建议。

The fourth chapter of the paper simulated the PRED coordination with the concept of PRED coordination index.

第四章对本区PRED系统关系的相互作用进行了总述，采用PRED协调度概念，对本区PRED协调情况进行模拟分析。

Again, you get this protective effect no matter what you drink - wine, beer, liquor or a fortified wine such as sherry, but the benefits don't increase with amount; and they disappear altogether if you consume four or more drinks per day.

再者，无论你喝的是哪种酒都可以收到同样的功效，你可以喝葡萄酒，啤酒，白酒或者是烈酒比如雪利酒，但是这酒对人体的益处并不随着量的增加而增加。如果你每天喝四杯或四杯以上的话，这些益处就会全部消失。

Article 144 The Government of the Hong Kong Special Administrative Region shall maintain the policy previously practised in Hong Kong in respect of subventions for non-governmental organizations in fields such as education, medicine and health, culture, art, recreation, sports, social welfare and social

第一百四十四条香港特别行政区政府保持原在香港实行的对教育、医疗卫生、文化、艺术、康乐、体育、社会福利、社会工作等方面的民间团体机构的资助政策。原在香港各资助机构任职的人员均可根据原有制度继续受聘。

For maintain the genome integrity and fidelity. DNA repair processes are classified into pathways responsible for repairing specific classes of DNA damage, although recent data indicated that some proteins function in multiple pathways. Base excision repair occurs through excision of a damaged region, followed by fill-in repair synthesis using the opposite strand as a template. Mismatch repair operates on base mismatched and small loop-outs that arising during replication by misincorporation or slippage on the template strand. Nucleotide excision repair removes photoproducts from u.v. radiaton and bulky adducts from a multiple of chemicals. DNA double-strand breaks may be rectified by either homologous recombination repair and nonhomologous end joining pathways where both strands of the DNA duplex are damaged.

DNA修补基因可藉由不同的机制对不同程度的DNA损害进行修复，虽然近来已有文献指出，一些DNA修复蛋白可能参与多种DNA修复机制，不过一般可分为下列四种DNA修复机制：碱基删除修复(Base Excision Repair； BER)，即对较小的DNA损伤，进行修复；核苷酸错误配对删除修复，即对复制时所产生的核苷酸配对错误或模板滑动造成的DNA损害进行修复；核苷酸删除修复(Nucleotide Excision Repair； NER)，即对因紫外线或有机化合物所造成的较大损伤进行修复；以及双股DNA断裂修复(Double-Strand Breaks； DSBs)，即对双股DNA断裂进行修复，此机制又可分为同源染色体的重组与末端接合两种主要路径，对受损的DNA进行修复。
