The expression of the boundary condition for plane stress problems by using the Cauchy type integral formula in the elasticity theory is investigated.

在研究中依据弹性理论的柯西型积分，建立适合於各种载荷作用轮齿不同位置的齿轮强度分析数学模型。

To study the taxiing-induced dynamic response of the aircraft with multiple wheels and multiple landing gears due to runway unevenness, base on several reasonable and necessary assumptions, the mathematical model of aircraft in taxiing is established using the d'alembert's principle. It can simulate taxiing inpact properties accurately, it considers in detail the vertical and horizontal motion and pitching about its center of gravity and the significant symmetric elastic modes.

在一些必要合理的假设下，利用达朗贝尔原理，建立了多轮多支柱式及小车式起落架飞机地面滑跑动态响应分析的全机模型，考虑全机沉浮、机体弹性和定常气动力的影响，起落架支柱的弹性变形，小车式起落架的车架的俯仰运动以及弹性变形，对等速滑跑飞机建立了全机运动的微分方程，并以旧金山28-R跑道为地面输入，利用时域积分的方法得到飞机滑跑的各种响应。

Parma boss Stefano Pioli was still looking for his first Serie A victory with just one point to his name so far and was missing Massimo Paci, sitting out a two-match ban for having simulated an elbow from Luca Toni, and the injured Andrea Gasbarroni and Zlatan Muslimovic.

帕尔马的主教练 Stefano Pioli 也同样非常渴望取得他执教意甲联赛的第一场胜利，之前的三轮联赛他只取得了一个积分，这与他的期望相差很远。但是帕辛因为在上一轮的比赛中肘击托尼而遭到了两场联赛禁赛的惩罚而缺席这场比赛，另外，加斯巴罗尼和穆斯里莫维奇也都因伤缺阵。

On the basis of general double closed-loops PID position tracking design of theodilite, the step-by-step integral separate PID control method is introduced, the calculation shows that it can effectively restrain overshoot, track position smoothly, and is helpful to reaction wheel control.

在通常的经纬仪双闭环PID位置跟踪设计基础上，在位置环引入步进式积分分离PID控制策略，计算表明，其可以有效抑制超调，较为平缓的实现位置跟踪，利于反作用轮的角动量平衡作用。

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。
