不均一

Results The latent phase of the primary culture cells was 5-9 days, followed by 11-16 days of logarithmical proliferation; the plateau began at day 18-20. The subcultures showed 12-24 hours of latent phase, followed by 7-10 days of logarithmical proliferation, then entered the plateau (11-13 days). The hMSC expressed positive CD44 unanimously, but don′t expressed CD45. Low concentration of bFGF (10 μg·L-1) could stimulate the proliferation of hMSC significantly (P.05); while 25-100 μg·L-1 of bFGF could inhibit the ALP activity.

结果：原代培养细胞生长潜伏期5~9 d，对数增殖期11~16 d，生长平台期18~20 d；传代培养细胞生长潜伏期12~24 h，对数增殖期为7~10 d，11~13 d进入细胞生长平台期。hMSC均一表达CD44，不表达CD45.bFGF在较低浓度（10 μg·L-1）时即有显著的促进hMSC增殖的作用（P.05）， bFGF在25~100 μg·L-1对hMSC的ALP活性有较显著的抑制作用。

The cultured cells appeared morphologically as spindle-shape and the average number of colonies which form in primary culture was 43±11. MSCs were positive for CD44 and CD29 but negative for CD34, CD45 and HLA-DR with a phenotypical identity of 99%.

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.

通过建立的地板采暖系统动态热性能分析模型，得出了在蓄放热特性、运行方式和太阳辐射等因素耦合作用下的室内热环境及热量分配比例，提出了等效供热量的概念及计算公式，指出实际所需供热量应等于设计供热量加上等效供热量，并以大连为例，给出了等效供热量的修正系数，以新方法计算，阴天可减少设计供热量37％，晴天最大可以减少设计供热量43.3％，节能效果显著；集热蓄热墙式太阳房中，混凝土蓄热墙的室温均一化效果和对温度波的削减作用非常明显，当室外温度波动最大幅度超过10℃时，室温波幅不超过3℃，实验中300mm厚墙体内外表面温差超过10℃；墙体蓄热效率与集热效率随太阳辐射照度的变化呈相反的变化趋势；墙体厚度、材料、表面吸收率以及盖板透过率等因素对集热和蓄热效率均有较大的影响，存在一个最佳的墙体厚度值，使得墙体集热和蓄热综合性能最优；传统的蓄热墙夜间没有外保温，辐射散热损失很大，研究表明墙体外保温方式明显改善了蓄热墙夜间的散热性能，增加了向室内的供热量。

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.
