The techyte, formed during the time of ES3 (38.0~43.0 Ma) and with better stored property for oil and gas, has the characters of high alkalies (K2O+Na2O=10.22%~12.47%), high potassium (K2O/Na2O=0.69~1.88), high aluminium (Al2O3=17.82%~19.44%) and low titanium (TiO2=0.19%~0.67%), and belongs to the typical shoshonite series.

粗面岩的K-Ar年代学和地球化学表明，它们形成于沙三时期(38.0~43.0Ma)，具有富碱(K2O+Na2O=10.22%~12.47%)、富钾(K2O/Na2O=0.69~1.88)、高铝(Al2O3=17.82%~19.44%)、低钛(TiO2=0.19%~0.67%)的特点，属于典型的钾玄岩系。

The effect of characteristics, including concentration and flow velocity of absorbent and feeding gas, on the CO_2 absorption process has been widely investigated. And the active materials of different concentration, including Potassium phosphate tribasic、 Potassium tetraborate、 N-methyldiethanolamine、 2-Amido-2-methyl-l-propylacohol and Piperazine, were added in the absorbent, of which the effect has also been investigated.

主要考察了气液流速及其浓度等操作参数对CO_2吸收性能的影响；同时研究了在氨基酸盐吸收剂中添加各种活化剂，包括磷酸钾、硼酸钾、N-甲基二乙醇胺、2-氨基-2-甲基-1-丙醇和哌嗪对CO_2分离效果的影响；并对膜组件运行的稳定性进行了初步考察。

A pure and single K+ current of ultrarapid delayed rectifier K+ current or transient outware K+ current is respectively expressed on Xenopus Oocytes. This is a moderm pharmacological model for evaluation class Ⅲ antiarrhythmiv durgs, overcomes many defcts such as lacking human fresh cardiac muscle cells as material and co-expression of many currents on cell membrane. A new compound A1998 from Ocean material is evaluated in this model for class Ⅲ antiarrhythmic functions.

5和Kv4.2cDNA转录为mRNA，然后将其分别注入蟾蜍卵母细胞上：在蟾蜍卵母细胞上分别获得纯净、单一的超速延迟性整流钾电流(Ikur，ultrarapid delayed rectifier K+current)和瞬间外向钾电流(Ito，transient outward K+current)表达，克服以往在筛选评价抗心律失常药物时，人新鲜心肌细胞取材困难、多种电流在细胞膜表面共同表达等缺点，从而建立评价Ⅲ类抗心律失常药物的先进药理模型，并筛选具有Ⅲ类抗心律失常药理作用的新化合物A1998。

Our experiment showed that addition of benzydamine induced vasorelaxation in the denuded aorta precontracted with KCl in the normal krebs.

实验结果亦显示，benzydamine能抑制高钾所引起的收缩作用，并且藉由在无钙之Krebs溶液中，经benzydamine前处理的血管给予高钾刺激之后，再给予钙离子刺激血管收缩，发现其能抑制外钙内流所造成的血管收缩作用。
