The present calculation is validated by reasonable agreement of predicted ratio for syn and anti conformation of cGMP with experimental estimation, suggesting that our predicted concentration distribution of the cGMP and cGMPH conformers, as well the microscopic pKa values of various cGMPH conformers and phenomenological pKa of cGMPH, are reasonable.
我们预测了cGMP反式和顺式的构象分布，得到的计算结果与实验论证的很一致，这说明我们提出预测cGMP和cGMPH构象浓度分布，各种cGMPH构象pka值及cGMPH表观pka值的计算方法是合理的。
With representation of typical zeolites Y and ZSM-5, our energetic calculating results can well explain the results of Sreekumar et al about Thio-Claisen rearrangement with and without zeolite catalysts, which is that syn conformation is the main product without catalyst, while anti conformation is the only product with zeolite catalyst.
以Y和ZSM-5两种典型分子筛为例用能学计算结果能较好地解释Sreekumar等人有、无分子筛催化条件下Thio-Claisen重排手性反应结果，即：无催化剂时，反应产物以顺式为主，有分子筛介入时，只能生成反式产物。

成年人学英文的第一课和第二课刊出后，有数位读者写E-mail给我。有一位说道：「一篇文章的每一个单字都查到解释了，但整篇文章就是看不懂，怎麼办？」另一位说：「我的文法很差，没办法写完整的英文句子，要如何补救？」当发音和字汇都掌握住学习要领之后，剩下的就是「读」和「写」了，这才符合学习英文的正确步骤：听→说→读→写。台湾传统的学习方式由「写」开始，再「读」，然后才「说」，最后再去补救「听」力，可以说是背道而行，难怪效果不彰。那麼学习「读」的要诀是什麼呢？当然最重要的是能够了解整个句子的涵义。记得初中的时候背了很多文法规则，考试的分数虽然很高，但是对「读」的能力没有帮助。连那个时候流行的「英语九百句型」，也从来没有耐心读完过。然而我们今天能够看懂中文的文章，难道是因为我们熟悉中文的文法吗？答案是否定的。同样地，一个美国人虽然能阅读报纸，但是要求他做「英文文法分析」，他可能也会傻眼。英文的句子其实不需要去靠文法书中的规则去了解，文法书只应当作参考书，在有疑惑的时候才去查阅。平常应养成「约定成俗」的习惯，就是看别人怎麼用，然后「依样画葫芦」，日积月累，文法规则就化为无形了。因此，要训练「读」的技巧，不应该是靠文法规则，而是要多读。但是在读之前，要具备「了解句子」的基本能力，这就是我们的第三课─了解英文句子的要诀。了解英文句子的关键，在於先抓住「主词」和「动词」。看到一句很长的英文句子，不要害怕：先找主词，再找动词。动词如果是「及物动词」，再去找「受词」。主词、动词、受词之外，剩下的通通当做修饰语，有的修饰主词，有的修饰动词，有的修饰受词，有的修饰全句；任何两个完整的句子都可以用连接词连接起来。以上简单几句话，就是了解英文句子的基本观念。了解英文句子的第二步是熟悉英语的五种基本句型，其中前两种与不及物动词有关，后三种与及物动词有关。以下的句子中，用大括号表示{主词}或{受词}，中括号表示，剩下的部份都是修饰语。第一种与不及物动词有关的基本句型叫做「简单不及物句型」（Intransitive Verb，简称I），请背住以下五个句子

While the tissue spaces surrounding a few blood vessels wasAl and Fg positive, no Al or Fg positive cells were observed. In antemortem injurygroup, diffuse subarachnoid hemorrhage, cerebral edema, swelling or pyknotic neu-rons could be observed. The axons showed irregular swelling and disconnection at1～3h, marked swelling and disconnection at 6h, and retraction ball at 15h whichwas more remarkable at 24h after injury. The space between myelin sheaths andaxons was increased at 3～6h after injury. Tortuous and wavelike myelin sheathswhich adhered on axons incompletely, or even peeled off could be found from 15hto 24h after injury. Perinuclear lysis of Nissl bodies began at 24h after injury. Thenumber of GFAP positive cells in cerebrum and brain-stem increased significantlyfollowed by decrease, and then increased again, but the time courses of the changesin different areas of brain were not same. Al and Fg positive neural cells, mainlysurrounded blood vessels, with diffuse or peripherally distributed positive matter incytoplasm could be observed at 0.5h after injury. The number of Al or Fg positivecells and the intensity of immunoreaction increased with the time of injury. The areaof SYN positivity in medulla oblongata and pons decreased notably 3～6h afterinjury, then return to normal levels and continued to 24h after injury.
