￣（45）Ca跨膜流动测定技术用于中药钙拮抗作用的研究

应用￣（４５）Ｃａ跨膜流动测定技术研究钙拮抗剂ｖｅｒａｐａｍｉｌ、中药西红花（ＣｒｏｃｕｓＳａｔｉｖｕｓＬ．）、“地奥心血康”（ＤＡＸＸＫ）、川红花（ＣａｒｔｈａｍｕｓｔｉｎｃｔｏｒｉｕｓＬ．）及银杏叶（ＧｉｎｋｇｏｂｉｌｏｂａＬ．）等对大鼠主动脉￣（４５）Ｃａ跨膜内流的作用，以确定其对细胞膜Ｃａ￣（２＋）通道影响。实验结果表明：西红花、川红花、ＤＡＸＸＫ对平滑肌细胞膜上电压依赖Ｃａ￣（２＋）通道（ＰＤＣ）和受体操纵Ｃａ￣（２＋）通道（ＲＯＣ）都有阻滞作用，并以西红花的阻滞作用最强；而银杏叶对细胞膜Ｃａ￣（２＋）通道无阻滞作用。     

楊廉夫名“楨”“禎”二字考

楊廉夫為元末明初的著名詩人、書法家,表字廉夫,其名維楨,亦作維禎。楊廉夫之名二字混用由來已久。《四庫全書總目提要》未對“楨”“禎”二字作考證,直以“楨”字》是。本文通過對歷代目志、石刻碑誌材料、楊廉夫法真蹟與印鑒題識以及方志材料等多個方面的考察,證實楊廉夫本名應作“楊維楨”,楊氏文集中“楨”“禎”混雜的現象,並非刊刻傳抄過程中形成的訛誤,而是始自楊廉夫本人對二字的有意混用。

DrugFET的研究（XⅢ）：四苯硼钠一烟碱FET的研制与应用

本文将离子敏感场效应晶体管（ＩＳＦＥＴ）与药物敏感膜相结合,研制成一种药物敏感场效应晶体管传感器（ＤｒｕｇＦＥＴ）。用四苯硼钠为电活性物质,邻苯二甲酸二辛酯为增塑剂,制成ｐｖｃ膜,对烟碱的线性范围为１．０×１０－２～２．０×１０－５ｍｏｌ／Ｌ,斜率为５７．５ｍｖ／ｐｃ,适宜ｐＨ范围为５．５～８．０,检出限为１．０×１０－６ｍｏｌ／Ｌ。用该传感器分析烟草中烟碱的含量,结果和分光光度法相一致。     

Harmony Theory

To aim directly at the negative effectiveness widely existing in socio-economic sys-tems,this paper puts forward a framework of "harmony theory"which can decrease the negativeeffectiveness and guarantee systems to be stably developing.     

Synthesis of glucoside compounds of ferrocenyl phenols and their antianemic activity

Six glucoside compounds have been synthesized by means of phase-transfer catalytic method and deacetylation from the starting material ferrocene. Their structures have been confirmed by elementary analysis, IR,¹HNMR and MS. The antianemic activities of some compounds have also been tested. Results indicate that these glucoside compounds possess the antianemic activities and therefore, the further study is well worth making.

H∞ control for stochastic systems with time-delay

The H∞-control problem of stochastic systems with time-delay is considered. The sufficient conditions are obtained, under which there are always state-feedback control and dynamic output-feedback control so that the resulting closed-loop system is internaly stable and L2 input-output stable in the sense of expectation. Furthermore, the explicit formulas of both kinds of controls are derived. An example is included to illustrate the correctness of theoretic results.     

二元变系数欧拉函数方程φ(ab)=15φ(a)+17φ(b)的正整数解

目的研究欧拉函数方程φ(ab)=15φ(a)+17φ(b)正整数解的问题,其中a,b为不小于2的正整数。方法利用初等数论方法和欧拉函数的性质。结果与结论得到该方程所有80组正整数解,并解决了张四保等在文献中(张四保,席小忠.有关方程φ(ab)=k(φ(a)+φ(b))的正整数解[J].南京师大学报(自然科学版),2016,39(1):41-47.)所提出的一个数学问题。
