他的作品若表现愉悦，必是中规中矩的欢乐，若是反映痛苦与忧郁，也不会有人对此产生置疑，这种规格化的情感表达在海顿早期作品中体现得尤为明显。

A modified Particle Swarm Optimization algorithm is proposed and used to optimize the sidelobe level of plane arrays, in which special techniques as global best perturbation and jumped inertia weight strategy are adopted. The PSO algorithm is also used to select a better combination of optimal parameters for itself.

摘要该文运用一种改进的粒子群优化算法对不等幅激励的矩形平面阵列天线的最大旁瓣电平进行了优化，采用对全局最优粒子微扰和跳变的惯性权重策略，并使用粒子群算法本身对参数组合进行了优化选择。

PFDoA对大鼠的毒性作用呈现一定的剂量依赖关系，主要表现在脂蛋白、不饱和脂肪酸的剂量依赖性下降和葡萄糖、柠檬酸、甲酸、异亮氨酸、缬氨酸的剂量依赖性升高。

In the forth part, we mainly discuss the properties of cosine operators, such as the normcontinuity, locally Lipschitz continuity, which are preserved under the multiplicative perturbation with the-condition.

第四部分讨论了余弦算子在条件下的乘积扰动和扰动下的不变性。如条件下的乘积扰动仍保持范数连续、局部Lipschitz连续不变。

Therefore, compared to the case without spiral arm perturbation, the curve F∝ log M, which is a measure of the formation rate of more massive clouds in the whole disk, is just displaced upwards and the amount of GMCs with intermediate mass, i.e., those with mass in the range between 10 5 and 10 6 M ⊙, will hardly be affected.
