Multivalued functional differential equations and integrodifferential equations are an important branch in the theory of nonlinear analysis, which have wide applications in many fields such as engineering, economics, optimal control and optimization theory.

多值泛函微分方程和积分微分方程是非线性分析理论的一个重要分支，它在工程、经济、最优控制及最优化理论等领域有着广泛的应用。

Descending brain neurons for transferring antennal sensory information have their major dendrite in the lateral deutocenebrum;they can transfer outside stimulative information to locomotory centrum to control walking,incepti...

传递触角感觉信息的下行脑神经元分支多聚集在中脑；外界刺激信息通过下行脑神经元传递到运动中枢支配行走，同时不断接收听觉、视觉信息调整行走的速度和方向。

Results The lesion located at the basal segments of left lower lobe in 9 cases (90%), furthermore, 7(70%) at the posterior basal segments; The remainder 1 case (10%) was found at the posterior basal segment of right lower lobe; The lesion present as multiloculated cyst containing fluid and/or air in 7 cases(70%) without contrast enhancement of cyst wall, 3 cases (30%) presented as irregular mass with moderate enhancement, in which bronchiectasis with mucous impaction, calcification or cyst containing fluid may be seen; MRP, MIP and VR reconstructions showed anomalous branches arising from descending aorta in all 10 patients(100%) with draining into left atrium via pulmonary vein,which was consistent with surgery; Ipsilateral hilar lymphadenopathy was demonstrated in 7 cases (70%).

结果 9例（90％）病灶位于左下叶基底段，其中7例（70％）位于左下叶后基底段，1例（10％）位于右下叶后基底段；7例（70％）病灶表现为含液/气的薄壁多房囊腔，增强后囊壁无明显强化，3例（30％）表现为不规则团块，增强后有中等强化，其内有粘液嵌塞的扩张支气管，也可有钙化或液性区；MPR、MIP及VR等三维重建显示10例（100％）均为降主动脉发出异常分支供血，并通过肺静脉回流入左房，血管显示情况与手术相符；7例（70％）患侧肺门淋巴结有增大。

The analysis indicates that the genus Metagentiana is polyphyletic, because all sampled species of Tripterospermum and Crawfurdia are clearly embedded within Metagentiana. The species of Tripterospermum and Crawfurdia also did not cluster respectively as two monophyletic clades. These results do not merit status of three separate genera.

ITS分析结果表明狭蕊龙胆属是一个多系群：在系统发育树上，双蝴蝶属Tripterospermum和蔓龙胆属Crawfurdia的种类位于狭蕊龙胆属各分支中，而且双蝴蝶属和蔓龙胆属的种类也相互交叉；这一结果不支持将3个属各自独立为属。

RESULTS: After 24 hours of preinduction, cells changed from spindle to polygonal or irregular, with many short rod-shape processes and 2-3 nucleoli. Whirlpool shape growth disappeared, and was disordered. After 1-3 hours of induction, cells gradually became round, with significant cell contraction, strong refraction, bipolar or pluripolar processes connected each other into a net. After 5 hours of induction, grades one and two branches were detected.

结果：预诱导24 h，胞体由原来的长梭形变成多角形或不规则形，伸出多个短棒状突起，可见2~3个核仁，细胞间漩涡状生长趋势消失，排列无规律；诱导1~3 h，细胞逐渐变圆，胞质收缩明显，折光性增强，双级或多极的突起互相连接呈网状；诱导5 h，突起出现一、二级分支。

By employing the theory of bifurcations of dynamical systems, the existence of solitary travelling wave solutions, uncountably infinite many smooth periodic wave solutions and non-smooth periodic travelling wave solutions, is obtained.

通过运用动力系统分支理论，获得了系统在各种参数条件下可能存在的孤立行波解、不可数无穷多光滑周期行波解和不光滑行波解，并就不同参数条件，给出了上述解存在的充分条件。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
