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。

The feldspars of topaz-lepidolite granite in Yashan late stage are P-rich albite and Kfeldspar, and the phosphorus goes into feldspar structure in the form of PAlSi〓 substitution. The phosphorus contents of feldspars vary according to their crystal habitus. In general, the feldspars of later generation have the higher average phosphorus content than that of earlier generation, and the albite contains higher phosphorus than the K-feldspar in the same generation. The zircon is highly rich in Hf, U, P and Al. The phosphorus enters the zircon structure mainly by the form of〓P〓〓Si〓, Al〓P〓Si〓 or P〓Al〓Si〓, Zr〓 substitution. The P-rich zircon is the production of the highly evolved magma, and it might be one of the important characteristic minerals of the high-P subtype granite.

Based on a computing model of floor heating residences, indoor thermal environment and heat distribution under the effect of heat charge/discharge, operation control and solar radiation has been concluded. Concept and formula of equivalent heat supply has been put forward which indicate that actual heat supply will be equal to the sum of design heat supply and equivalent heat supply. Recommend coefficient has been given taken Dalian as an example. Computed according to the new method, design heat supply can be reduced to 37% in cloudy day and 43.3% in sunny day, energy saving effect is very obvious. In Tromb wall solar house, effect of concrete wall on indoor temperature swing and attenuation of temperature wave is very obvious. While the outdoor air-temperature swing exceeds 10℃, indoor air-temperature swing belows 3℃. In the experiment, maximal difference in temperature between inner surface and outer surface of the 300mm wall exceeded 10℃. Heat storage and collector efficiency varies adversely according to solar radiation. Factors such as thickness, material, absorptance of the wall and permeation of the glass cover all have big influence on heat storage and collector efficiency. There exsisted an optimal thickness of the wall, which can make the best of heat storage and collector efficiency. Most of the heat stored in conventional Trombe wall during the daytime has been lost to the outside at night without heat preservation. Heat preservation on the outside surface of the wall has effectively improved heat release performance of the wall at night, heat supply to the room has increased too.

Analyzing the model, especially the activity of Taihang Mountain piedmont fault, we got such main conclusion:1. Based on sequence stratigraphy, the strata is divided from the selected drills. And the Quaternary stratigraphic framework of Handan city is established, dividing the Quaternary strata into four parts- Qh, Qp3O , Qp2Y and Qp1G.2. With all the selected drill data of Handan city, a drill database is established. A quaternary strata 3D model of Handan city is imitated by GOCAD and ArcGIS, and so are the bottom structural map of each horizon.3. Analyzing the 3D model and the contradistinction section of drills, we got: the stratum of Qh and Qp3 is smooth and flat, with a feature of a higher west, little difference between south and north and undistinctness of faults; there are several depocenters along S-N and N-W in the stratum of Qp2, and the evolution of the stratum is controlled by a couple of ruptures, which means the tectonic movement is active in this period of time.4. Since quaternary, main tectonic movements happened in Qp2 and have been stable in Qp3 and Qh.

The following main results are obtained: The TiO_2 photocatalyst with small crystallite size, high surface area, narrow and uniform pore size distribution, and microporous frameworks could be prepared out by applying MW radiation in the preparation process. The microwave-induced fluorescence technique verified for the first time that microwave enhanced the formation rate of hydroxyl radical, leading to the increase in the photocatalytic efficiency. Compared with the conventional catalyst, TiO_2 prepared by MW dielectric heating owns a higher UV absorption ability, and its optical absorption edge and photovoltaic response are shifted toward the short wavelength region, resulting in increase of photooxidation efficiency. The photocatalytic conversion and the mineralization ratio of acetaldehyde are increased respectively by 30% and 40% over the TiO2 prepared by MW radiation when compared to the TiO2 prepared by the conventional heating. For the MW-assisted photocatalytic reaction over the MW-prepared TiO2, production of hydroxyl radicals is enhanced by 22.5%, and the photocatalytic conversion is accordingly increased by 20%. Similarlly, applying MW also increased the photocatalytic conversion and the mineralization ratio of acetaldehyde over TiO2/Al2O3 sample.
