In the world the chilliest beautiful distance is two people originallyis away from very far, mutually is not acquainted with one another,suddenly one day, they are acquainted with one another, fall in love,the distance changes very much near.

This seems also like a long ways away to be causing this kind of damage; but considering Niburu is 5 times the size of earth, has 25 times the mass, and is 100 times more dense than earth; in fact it is one of the most devastating distances Niburu could be and here's why, according to Mark Hazelwood.

那看起来好像是一个很长的距离，不会引起这种损害，但考虑到nibiru是地球的5倍大，质量是地球的25倍，密度比地球大100倍，事实上，这个距离是nibiru最能造成毁坏的距离之一，那也是为什么Mark Hazelwood会说&一个巨人从旁通过&。nibiru过境仅会偶尔造成极移，但它通过时总是给地球带来严重损坏，在地球上留下了极具毁灭性的印记。

Finally, regression analysis shows that, isolation by distance exists in rhesus macaques.

最后，遗传距离和地理距离之间的回归分析表明，在恒河猴的群体中存在距离隔离效应。

By establishing a model based on the law of infrared radiation transmission in atmosphere and the characteristics of infrared imaging system for the apparent contrast between the target and the background, and analyzing the model over two wavebands to formulate the distance measuring formula and the distance resolving power formula, a passive distance measurement method is proposed for aerial point target distance measurement.

提出了对空中点目标进行被动测距的方法。基于红外辐射在大气中的传输规律和红外成像系统的特性，建立了目标和背景的表观对比度模型。通过对两个波段上对比度模型的分析，推导出了测距公式和距离分辨率公式。理论分析表明，只要得到大气在两个波段上的消光系数，通过测量目标在两个波段、两个时刻上的目标表观对比度，即可计算得到目标距离和目标径向速度，而距离分辨率则取决于系统的对比度探测能力及相关参数。

Participants required more time to shift their focus over the imaged stimulus in the KBR paradigm. More fixations,more saccades,and rarer saccade distance were found when they scanned in the KBR task.Detailed analysis showed that participants scanned the whole distance from the original point to the target point in KBR paradigm,while the scanning distance were much shorter in FP paradigm.

在距离相同的情况下，被试完成KBR任务需要更多的时间，眼动特征表明，被试在完成KBR任务时，需要更多的注视点、眼跳次数和更远的眼跳距离，对眼动轨迹图的分析显示，完成KBR任务时，被试进行的是从初始点到目标点的全程扫描，而完成FP任务时，扫描距离较短。

It is one of the most dominant small mammals and plays an important role in keeping the balance of the alpine meadow ecosystem.The aim of this paper was to investigate the level of genetic diversity and also to test the hypothesis of IBD for this old species.Samples of plateau pikas were collected from four natural populations（Haiyan,Xidatan E,Xidatan W and Kunlunshan populations）.

采用多态信息含量、期望杂合度、观测杂合度、基因流和基因分化系数对种群及物种的遗传多样性水平进行分析；计算各种群间的遗传距离、遗传相似度以及遗传距离与地理距离的相关系数，并进行UPGMA聚类分析。

Using Field single ignition experiments of the four unconfined volume dispersion and small dosage solid FAE and TNT bombs experiments, we got the peak overpressures of solid FAE at different distances. Compared with TNT, The overpressure of FAE is 1.14~1.6 times higher than that of the TNT. Based on the theory of the air shock wave overpressure, the FAE relativity TNT mass is evaluated. At the edge of the explosive field, the number is 3.88. Pictures of high speed photography indicate that the duration and the most effect area of the FAE and TNT. Compared with TNT, obviously the FAE has more advantages. And, based on the theory of the critical concentration of dust explosion, the radius of dust explosive zone is evaluated. The phenomenon that the overpressure decays rapidly with distance is analyzed. It is suggested that the explosive temperature should be increased as the main approach to improve the FAE explosive capability in the condition when the over pressure is invariable.

通过四组无约束固态燃料空气炸药装置与等质量的TNT在野外开放空间的一次起爆对比实验，测得了不同配方组份FAE装置在不同距离的爆炸超压分布，FAE装置峰值超压比相同距离的TNT高1.14-1.6倍；并运用空气冲击波峰值超压公式计算出了FAE的等效爆炸TNT当量随距离的变化关系，在爆炸场边缘区，FAE装置爆炸当量达到了3.88倍TNT当量；通过高速摄影的图片得到了爆炸产生火球的持续时间和最大作用范围，与等质量TNT爆炸火球相比，FAE的优势明显；运用粉尘爆炸下极限浓度估算了云雾爆轰区半径，并分析了测量到的固态FAE爆炸场的压力分布单调衰减的原因；建议在保持超压不变的情况下，把提高爆温作为提高FAE爆炸性能的主要途径。
