Based on the ICMmethod,the discrete topological optimization problem about spot-weld's existence or not is transformed into the continuous optimization problem on[0,1].The optimization model is founded with maximizing the structural stiffness as objective and structural strength as constraints.The problem of multi-objectives and multi-constraints is transformed into the problem of single-objective and single-constraint with the K-S function.The displacement and stress are transformed into the explicit function of design variables with the Response Surface Methodology.The optimization model is solved with Sequential Quadratic Program.

分析结果表明，体外无粘结预应力钢筋截面面积沿长度方向的变化，引起结构可靠指标的降低是比较明显的，可靠指标随着独立同分布随机变量的数目的增大而减小。

Scores of omatization, sensitivity of interpersonal relation, depression, anxiety, hostility, fear, monomania, psychiatric and total scores, total average scores, positive numbers, positive average numbers of the experimental group were higher than those of the control group（P＜0.01）. Correlation analysis showed that age was positively correlated with the mood of depression and negative copying（P＜0.05）, educational level was negatively correlated with the mood of depression and anxiety, and serum albumin was negatively correlated with negative copying（P＜0.05）. Conclusion: The mood of depression and anxiety is an obvious symptom in nondialysis patients with chronic kidney disease.

结果：慢性肾脏疾病组焦虑情绪、抑郁情绪和消极应对显著高于对照组（P＜0.01）；人格类型稳定性两组相比差异有统计学意义（P＜0.01）；两组心理健康状况相比，躯体化、人际关系敏感、抑郁、焦虑、敌对、恐惧、偏执、精神病性及总分、总均分、阳性数、阳性均数差异均有统计学意义（P＜0.01）；心理指标与被试变量的相关性分析显示年龄与抑郁、消极应对呈正相关（P＜0.05）；受教育程度与焦虑、抑郁呈负相关（P＜0.05）；血清白蛋白与消极应对呈负相关（P＜0.05）；而性别、职业、肾功能、血红蛋白与焦虑抑郁情绪、应对方式及心理健康状况总分、总均分、阳性数无相关性。

Multiplier and multiplicand were distinguished on multiplications with different coding methods.

算法在单向无环图上计算距离，提取出变量的分组和结合顺序；对不同编码方式的乘法器，识别乘数和被乘数的结合顺序。

In this paper a Nonlinear Variable Dimension Estimator is proposed for tracking maneuvering spacecraft. Two process models were incorporated by the Unscented Kalman Filter to account for the dynamic uncertainties of the target of interest: a nonmaneuvering model based on the two body problem and a maneuvering model taking the forced acceleration as the unknown system input to be estimated.

当飞行器处于无机动的巡航状态时，无色卡尔曼滤波器使用常规的二体问题模型描述其运动规律，而当飞行器被认为开始机动后，滤波器将扩展系统的状态空间，将机动加速度作为状态变量进行估计，从而增加了模型的适应性。

It supports directed and undirected models, discrete and continuous variables, various inference and learning algorithms.

它支持有向或无向的模型，离散或连续的变量，各种推论及学习算法。

This is viable because Lua does not perform type checking because all variables are untyped.

这是可行的，因为lua并不进行类型检查——所有变量都是无类型的。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
