In the DQ/EG homogeneous solution, the enhanced emissive CIDEP signal of the neutral durosemiquinone radical DQH(superscript ﹒) was observed. When the DQ/EG solution with pH=9 or DQ/EG/TX-100/H2O micelle system was photolyzed, the CIDEP signal of the duroquinone anion radical DQ(superscript ﹒- was obtained. When the DQ/EG solution with pH=2.5 was irradiated, the CIDEP signal of DQH(superscript ﹒) appeared.

在光解均相DQ/EG溶液时，观察到了以增强发射的中性杜半醌自由基DQH(上标﹒的CIDEP信号；在碱性环境下(pH=9)和TX-100胶束环境下光解DQ/EG体系时得到杜醌负离子自由基DQ(上标-﹒的CIDEP信号；在酸性环境下(pH=2.5)光解DQ/EG体系时，出现的又是中性杜半醌自由基DQH(上标﹒的CIDEP信号。

In order to utilize the mapping channel of epicardial mapping system effectively,we present a new mapping method with feedback adjustment.

为了有效地利用心外膜标测系统的标测通道，提出了一种带反馈调节的标测方法。

The slices were divided into two groups. In group I, the slices were perfused with 5-HT(subscript 2A) receptor excitomotory-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane dissolved in modified Kreb's solution. In group Ⅱ, the slices were perfused with ketanserine specific antagonist of 5-HT(subscript 2A) receptor. The effects of DOI and ketanserine on RRDA were observed.

标本分2组：第1组使用含5-HT(下标 2A)受体特异激动剂2，5-二甲氧基－4-碘苯基丙烷的Kreb's液灌流脑片，观察其对RRDA的影响；第2组使用含5-HT(下标 2A)受体特异拮抗剂酮舍林的Kreb's液灌流脑片，观察其对RRDA的影响。

The results indicate that LG in hexahydric alloys can be studied by proper transformi. Using ΔGR can be calculated. R decrease with increase of T、γ and D. The calculated results show e the method is feasible. By line fitting the relationship between R and D(superscript -0.73653 subscript max) is linear and regression equation is prominent

结果发现，通过适当的处理，可以计算六元合金系的ΔG；用ΔG值计算出六元合金系的R，R分别随约化玻璃转变温度T(下标 rg、γ和最大直径D(下标 max的增大而减小，说明此计算方法是正确的；通过线性拟合，R与最大直径D(下标 max的-0.73653次方是相关的，相关性显著。

Results indicated that Hoolock gibbons tended to inhabit eastern slopes E(subscript i= 0.344 as they were relatively windproof. They also favoured the tree species Querucus acutissima E(subscript i=0.455 and Eurya pseudocerasifera E(subscript i=0.068 for their large crown, as they provide more continual movement routes and large spaces for the gibbons, compared with other plant species.

定性因子分析表明，白眉长臂猿偏爱在东坡E(下标 i=0.344活动，可能与其能提供避风的温暖微生境有关；偏爱栓皮栋E(下标 i=0.455和拟樱叶柃E(下标 i=0.068等乔木，可能是由于这些树种的树冠面积大，可为白眉长臂猿提供连续的移动路线和大的活动空间。

The mechanism of removing Zn(superscript 2+) has formed the chelating agent of hydroxamic acid group and Zn(superscript 2+), and the concentration of its maceration extract by water is 1/51 of the neutralization method's, so it is provided with better stability and environment safety.

捕集剂去除Zn(上标 2+)的反应机理为羟肟酸基团与Zn(上标 2+)形成了稳定的螯合物。摘集剂与Zn(上标 2+)反应形成的沉降物的浸出量仅为中和法沉淀的1/51，具有较高的稳定性和环境安全性。

Methods:We ablated the ventricular tachycardia of 12 patients with normal hearts by the catheter, using pace mapping and activation sequence mapping. The former original target was the site where the pacing QRS was entirely consistent with IVT(Idiopathetic Ventricular Tachycardia) attack. And the latter original target was the site of in advance of earliest high frequency and low amplitude local potential on surface electrocardiogram QRS≥20ms, using activation sequence mapping. Results: Among 12 patients, the IVT originated from right ventricle in 2 patients, from left ventricle in 10 patients.

对12例正常心脏室速进行导管消融，采用起搏标测与激动顺序标测，前者以起搏时与室速QRS波型形态完全相同，后者以激动顺序标测法定位，以记录心动过速时较体表心电图QRS提前≥20ms的最早高频低振幅局部电位处为消融靶点，结果：12例患者室速起源部位分别为：右心室2例，左心室10例，疗效100%。

Extensible Markup Language ,or XML, is also derived from SGML,,However, unlike HTML,XML uses markup tags to describe the meaning, or semantics, of the text ,rather than its display characteristics, XML offers businesses hope for a common language that they will be able to use to describe products, services, and even business processes to ech other in common, shared databases, XML could help companies dramatically reduce the costs of handling intercompany information flows

可扩展标识表记标帜说话，或XML ，也是来自SGML的，，可是，分歧的HTML ， XML的利用标识表记标帜来形貌标识表记标帜的寄义，或语义，笔墨，而不是其表现的特点， XML的企业但愿供给一个配合的说话他们将可以或许利用申明的产物，办事，乃至营业流程，舍其他配合说话，配合的数据库， XML的可帮忙企业大幅度低落处置公司内部的信息活动的本钱

According to the results of this study, the owner should take action on the drawbacks of building industry system. For example, firstly, the purchase system should be reformed to avoid the malignment competition; secondly, the content of project contract must be reviewed to set up the fair and reasonable contract by the responsible attitude and the additional agreements; thirdly, the professional ability on the area of purchase of clerk should be improved. The design supervise should have professional ability to supply technical service and should be responsible for the loss which caused by the improper design.
