The rate of c-kit+ cells in the heart increased gradually from E10 with the highest level of 12.6±3.2% at E11, which was nearly similar to the fetal liver, except for E12 when the c-kit+ cells was 3.4±1.2% in the heart compared to the fetal liver with 11.6±4.1% c-kit+ cells. The rate of c-kit cells in the suspension cells from the heart at E11 maintained stable after 24h culture based in the stromal cells of the heart and AGM region with the same conceptus age, but the rate of c-kit cells obviously decreased in the condition of the stromal cells from the fetal liver. The c-kit cells of the three conditions were all at low level at 48h without significant difference.

通过流式检测c-kit+细胞我们发现，胚胎期心脏和胎肝c-kit+细胞比率几乎一致，E11时c-kit+细胞明显增多，分别高达(12.6±3.2)%和(9.6±2.8)%，但E12时心脏中c-kit+细胞明显减少，仅为(3.4±1.2)%，此时胎肝中c-kit+细胞为(11.6±4.1)%。E11的悬浮细胞与心脏内皮细胞和AGM区基质共培养24h时，c-kit+细胞数量保持稳定，但在胎肝基质细胞中c-kit+细胞数量明显减少，在共培养48h，三组中的c-kit+细胞均呈较低水平，组间没有显著性差异。

In terms of the synoptic environment and precipitation characteristics, there were some common characteristics in these two cases. For instance, warm and moist air with the conditional instability atmosphere in the lower troposphere, it was associated with the highest equivalent potential temperature gradient and strong moisture contrast to below 700 hPa. The lower-level convergence was the major produced mechanism of MCS and the low-level southwesterly flow generated convective instability.

从综观环境条件与降水特徵显示，两个案共通特徵包括（1）低对流层属暖湿条件性不稳定大气，（2）最大相当位温梯度以及水气梯度分布於700 hPa以下，（3）低层辐合均为个案中MCS之重要激发机制，（4）有明显低层西南喷流，大气呈现对流性不稳定状态，（5）中层短波槽线的移入，以及（6）高层辐散分流场的存在，提供MCS发展的有利环境条件。

Therefore, the moist potential vorticity analysis associated with the mesoscale convective system was researched in the paper, so as to reveal the moist potential characteristics of mesoscale convective system in typhoon circulation. The results showed that, during the generation stage, convective instability characterized by MPV1 was a favorable condition for forming MCS, while the vorticity which was caused by the slantwise isentropic surface and the vertical shear of the horizontal wind characterized by MPV2 was an inspiring mechanism. The specific process was that, the atmosphere exhibited the feature of strong convective instability at the low level of convection areas and the southeast areas, which included plenty of erratic energy. The slantwise ascended the stream transfer the erratic energy to northwest, where the stratification stability was small. As decreased, the cyclonic vorticity increased. On the other hand, the vorticity caused by the slantwise isentropic surface and the vertical shear of the horizontal wind inspired the release of convective instability and as a result that the MCS formed. During the development stage, the cyclonic vorticity increased quickly with the persistent decreasing of . Meanwhile, the inclination of isentropic linewas bigger than the absolute momentum line at middle level, which exhibited the feature of conditional symmetric instability , then the conditional symmetric instability was forced to release by the vorticity resulted from the slantwise isentropic surface and the vertical shear of horizontal wind, and the MCS developed.

结果表明，在对流形成阶段，MPV1即对流不稳定为MCS的形成提供背景不稳定条件，由MPV2即湿等熵面的倾斜和水平风的垂直切变而引起的涡旋发展作为强迫机制：MCS形成的区域及东南区域中低层是强对流不稳定层，蕴含丰富的不稳定能量，倾斜上升运动把对流不稳定区具有强不稳定能量的暖湿空气向西北中层的中性层结区输送，由于的减小，气旋性涡度增强，有利于形成对流，另一方面，由于湿等熵面倾斜和低空急流加强而引起的涡旋发展作为一种强迫机制激发对流不稳定能量得到释放，从而形成对流；在对流系统地发展阶段，由于低层的对流不稳定性进一步减弱，进一步减小，气旋性涡度进一步增强，有利于MCS的增强，中层等θe 线的倾斜度比绝对动量M 等值线的倾斜度大，对应有条件对称不稳定区域，满足条件对称不稳定条件，在湿等熵面倾斜和台风低空急流作用下引起的涡旋发展强迫对称不稳定能量释放，从而使得对流得以维持和加强。
