UUV编队协同应召搜索马尔可夫运动目标的方法

采用时齐马尔可夫链来模拟目标的规避运动，根据事发海域的水深映射图，估算出马尔可夫运动目标的位置转移概率。无人水下航行器编队在目标初始概率分布和位置转移概率已知的条件下，根据当前搜索结果不断对目标位置进行预测和更新。编队成员能共享目标位置信息，以获得较为准确的目标验后分布。然后采用一种新的分区实时贪婪搜索算法，得到无人水下航行器编队的最优搜索路径，从而以较高的搜索成功概率与较短的平均发现目标时间完成对目标的应召搜索。最后通过实例仿真，证明了该方法的有效性和优越性。此方法将对无人水下航行器编队的战法研究具有参考借鉴意义。     

Performances of improved Tent chaos-based FM radar signal

A novel algorithm is proposed to solve the poor performance problem of the Tent chaos-based frequency modulation(FM) signal for range-Doppler imaging,which takes it into complex multi-segment system by increasing its segments.The simulation results show that the effectiveness of the proposed algorithm,as well as the performance of the improved Tent FM signal is obvious in a multipath or noise propagation environment.     

Magma flow inferred from magnetic fabrics in Wanning gabbro pluton and diabase dykes, Hainan

Measurements of anisotropy of magnetic susceptibility (AMS) were performed on a gabbro pluton and 7 diabase dykes in the Wanning area, southeast Hainan Island. Rock magnetism showed that pseudo-single domain (PSD) to multidomain (MD) Ti-poor magnetite carries the magnetic fabric in the gabbro pluton whereas MD Ti-poor magnetite carries the magnetic fabric in the diabase dykes. The corrected anisotropy degree (Pj ) in most specimens was found to be less than 1.2 which is indicative of a possible flow-related magnetic fabric. The AMS eigenvectors within each site are generally well grouped. The maximum susceptibility axes (K1 ) of the gabbro pluton are inclined towards the north at low angles (< 30°). K1 axes of the diabase dykes are inclined towards the NNW and SSE with dip angles of ≤ 30°. From this study, it appears that the emplacement mode of the gabbro pluton was characterized by intrusion from the north to the south at a low angle whereas the diabase dykes were emplaced from the NNW to the SSE at low to moderate angles. This was verified by comparison of the rock fabric to the magnetic fabric. All of this evidence leads to the conclusion that the Wanning gabbro pluton and diabase dykes were the products of pulsative intrusion from the same magma chamber in the area far to the north of Wanning, which suggests that basic rocks may exist beneath the Indosin- ian granite in the area to the north of Wanning.

试论艺术创作中激情的控制——以油画为例

激情是可调的,激情在创作过程中所运行的轨迹是变化多端可以控制的.激情控制的目的是克服激情在创作过程中的消极作用.创作激情只要找不到尽情宣泄的渠道,创作主体就会体验到一种莫名的焦虑感,这对艺术创作是不利的.“高峰体验”也佐证了在创作过程中不能一味凭借激情,去完成一次艺术创作.激情与技术的关系是非常密切的,在创作过程中二者互相依存,缺一不可.
