In this paper, we propose a new visual cryptographic method for gray-level and chromatic images without pixel expansion. We simultaneously encrypt m successive pixels (called an "encryption sequence") each time in accordance with two basis matrices. In every m encryption sequences with b blacks, we make sure that b encryption sequences are encoded by black basis matrix, and the other ones are encoded by white basis matrix.

本研究提出一种不需要像素扩展的灰阶和彩色视觉密码的技术；我们的方法利用多点同时加密的概念，每次取连续的 m 个点做为加密序列进行加密，我们的方法可以确保在 m 个具有 b 个黑点的加密序列中，一定会有 b 个加密序列是使用黑点基础矩阵加密，另外的个则使用白点基础矩阵加密，因此在叠合影像上黑与白的变化很规律。

Three facts that I'll never ever get wrong again are: the German Panther tank carried a .75 mm cannon, not an 88; in Michigan, at its Willow Run plant, the Ford Motor Company made B-24s, not B-17s; during training, medics were called chancre mechanics, not shank mechanics.

有三项事实在下再不会弄错：德国豹式坦克配备一门点75口径直射炮，不是88口径；福特汽车公司在密歇根威楼峦的飞机厂制造B-24型轰炸机，而非B-17型；集训期间，救护兵被称为梅毒修理工，并非脚杆修理工。

Cinnamomea, antrocamphin A was purified from previous ethanol extraction using bioactivity-guided fractionation. As results, the antrocamphin A could significantly inhibit NO and PGE2 autacoids production in LPS-induced RAW 264.7 macrophage cells. Meanwhile, the mRNA and protein expression levels of iNOS and COX-2 were inhibited by antrocamphin A in a dose-dependent manner. Antrocamphin A also reduced the translocation of NF-κB induced by LPS, which was associated with the prevention of the degradation of I-κB, and subsequently decreased p65/p50 proteins level in the nucleus. This is the first report demostrating the A.

接著并以活性为导向的分离策略，从樟芝子实体乙醇抽出物中分离出具抗发炎活性成分antrocamphin A，续利用LPS诱导小鼠巨噬细胞（RAW 264.7）产生发炎的模式，解析antrocamphin A之抗发炎机制，结果证实antrocamphin A确可有效抑制一氧化氮自由基和前列腺素的生成，透过蛋白质表现分析得知，antrocamphin A之抗发炎活性是经由抑制一氧化氮生成酵素和第二型环氧酵素的mRNA表现，进而抑制了一氧化氮生成酵素、第二型环氧酵素和核转录因子-κB等酵素之表现。

When A car alarm, traffic police can not find the B car, car B will be determined to escape.

当A车报警后，交警找不到B车，也会认定B车逃逸。

What is more, not only MIP which synthesizes as the template is bigger than other amino acids with C to the B mark A recognition selectivity recognition capability, moreover also far is bigger than B mark D the recognition capability.

有趣的是，用C作为模板合成的MIP对B标记的A的识别选择性不但大于其它氨基酸的识别能力，而且还远大于B标记的D的识别能力。
