Results The pD2 value (the affinity to M-receptors of agonist) of Erycibele alkaloid's miosis is 3.60±0.15 and its IOP lowering action is 3.49±0.07. In the isolated iris contracting experiment, its pD2 value is 6.38±0.12. M3 receptor antagonist is the strongest antagonist in inhibiting the miosis, IOP lowering action and isolated iris pupillary contracting action of Erycibele alkaloid. 0.01% Erycibele alkaloid can cause the decrease of cAMP and the increase of cGMP in the aqueous humor.

结果 测定丁公藤碱缩瞳作用的pD2值为3.60±0.15，降眼压作用的pD2值为3.49±0.07，离体虹膜收缩作用的pD2值为6.38±0.12.M1～M3受体拮抗剂均可拮抗丁公藤碱的缩瞳作用、降眼压作用及离体虹膜收缩作用，其中以M3受体拮抗剂的拮抗作用最强。0.01％丁公藤碱可使房水环磷酸腺苷(cyclic adenosine monophosphate，cAMP)含量降低，环磷酸鸟苷(cyclic guanosine 3，5-monophosphate；cGMP)含量升高。

Effects of microwave power, reaction time, reaction temperature, solvent etc. on reaction were studied by a single factor tests. The results show that maleic acid is more active than fumaric acid; the introduction of methyl group on the double bond can weak the reactivity of the Michael addition reaction; the ester base is more propitious to complete the Michael addition reaction than the nitrile base.

为研究微波下迈克尔反应的规律，本文采用单模聚焦微波有机合成仪，通过对顺丁烯二酸、反丁烯二酸和氨水合成DL-天冬氨酸、顺式3-甲基丁烯二酸和氨水合成3-甲基天冬氨酸、丙烯酸甲酯和氨水合成β-丙氨酸、丙烯腈和氨水合成β-氨基丙腈等五个反应对迈克尔加成反应进行了研究。

There are complicated difficulties in Plantinga's theory. In this essay, I start from the 4th factor of warrant : leading to truth, pointing out that under certain circumstance, this factor will demand the recogniser to distinguish truth and false. This demand is in conflict with the distinction of de jure question and de facto question, meanwhile it is not coherence with the externalism position insisted by Plantinga.

普兰丁格的理论包含着复杂的困难，本文从保证概念的&导向真理&这一规定入手，指出这条规定在某些情况下为保证概念提出了鉴别真假的责任，从因而与普兰丁格所提出的规范性问题与事实性问题的区分相冲突，也不符合普兰丁格所坚持的外在主义立场。
