By using properties of quasi-regular semigroups and left central idempotents, some statements are proved. Let S be a quasi-right semigroup, then (1) S is a quasi-completely regular semigroup;(2) RegS is a completely regular semigroup;(3) R(superscript *) is the smallest semilattice congruence on S;(4) Each R-class T(subscript α) on RegS is a right group;(5) T(subscript α)G(subscript α)×E(subscript α), where G(subscript α) is a group, E(subscript α) is a right zero semigroup.

A boiler water controlling system with basifier a mg/L Na3PO4+b mg/L NH3+c mg/L NaOH is investigate in the paper. Several calculate methods are discussed and the precision pH value calculating equation is proposed for a cycle chemistry system that has seven changing parameters coexisting together, i. e. a mg/L Na3PO4+b mg/L NH3+c mg/L NaOH+d mg/L H2SO4+e mg/L CH3COOH+f mg/L CO2+g mg/L SiO2. As an example of equilibrium phosphate treatment, the pH value are obtained and showed in graphics with the four kinds of impurity changing from 0 to 1.0 mg/L. The calculating results can be used in practical boiler water pH value control.

Azoreductase in E.coli.JM-109 can damage -N=N- to decolorize azo dye. Decolonization conditions,such as dye categories,temperature,pH,salinity,oxygen were studied in this article.E.coli.

由于E。 coli JM-109含有的偶氮还原酶能破坏偶氮染料的-N=N-使其脱色，因此本文考察了其脱色的条件（温度，pH，盐度，供氧量）及其适用范围。

At the BCL of 500ms, 1000ms and 2000ms,the VWtimes increased markedly with the BCL prolonging, and the degree of increasing was even obviously when heart rate was slow (BCL=2000ms or 1000ms). The enlargement of VWs was a most important reason to increase the incidence of ventricular arrhythmias; 2）At the BCL of 500ms, 1000ms or 2000ms,the VWtimes of the premature stimulates S2 was at endomembrane were wider than at the outermembrane. We supposed that premature stimulates come from endomembrane was easier inducing VF compared with outermembrane;3The VWtime of unidirectional block was wider than reentry's, we can see that reporlarization dispersion changed dynamicly. 4The QRS polar of the premature stimulates was opposite the primary beats ,which suggesting that excitation of inducing premature beats was coming from epicardial. That is to say electrotonic potential take part in the creation of reentry;5With the ratio of the Tp-e/QT increasing the occurrence of VF was upgrading. So the ratio was an effective method to estimate the event of SCD.6 The VWtimes of S3 were broaden than S2's. But we can not study penetratingly, which is the contents of our future studies.

在BCL为500ms、 1000ms和2000ms刺激条件下，随着刺激周长的增加单向传导阻滞时间易损窗呈增大趋势；并且在心率较慢时(BCL为2000ms和1000ms)增大最明显，是LQTS患者室性心律失常发生率增加的原因之一；2）在BCL为500ms、 1000ms和2000ms刺激条件下，S2位于内膜侧时时间易损窗大于在外膜侧时的，推测来自于内膜侧的期前刺激易于诱发室性心律失常；3）折返激动时间易损窗小于在单向传导阻滞时间易损窗，折返易发生于S2刚进入单向传导阻滞区间时，这说明复极梯度的不均一是动态变化的；4心电图上倒置QRS波与正常S1刺激所引起QRS波极性相反，提示不同位置S2刺激引发的室性早搏的兴奋均来自于外膜侧，说明了电紧张电位扩布参与了折返的产生；5）Tp－e/QT可以反应跨膜复极离散度，随着Tp－e/QT比值的增加PVT的发生增多，其可以用来预测室性心律失常的发生。6）随着期前刺激数目的增加时间易损窗增大。

Methods: Thirty male SpragueDawley rats were randomly divided into 5 groups, group A 3 days after L5 VRT, group B 7 days, group C 14 days, group D 21 days and group E of sham operation, whose left spine cords were exposed by hemilaminectomy. Rats in each group were respectively perfused with paraformaldehyde and materials were taken from L5 dosal root ganglions and the changes of expression of P2X3 receptor were observed with immunofluorescence staining.
