"If we can find the Mars Polar Lander and be convinced we understand what we're looking at, it might provide some clues as to what went wrong," says Alfred McEwen of the University of Arizona in Tucson, US.

"如果我们能够找到火星极区着陆器并且确信明白我们所看到图像的意义的话，我们也许就能得到一些任务失败原因的线索。"位于塔克森的亚利桑那大学的教授 Alfred McEwen 如是说。

北极熊是陆地上体形最大的肉食动物。

Other parts of the Arctic also experienced higher-than-normal temperatures, which indicate that the wider polar region may have experienced its hottest summer on record, according to Walt Meir of the US National Snow and Ice Data Centre in Colorado.

其他部分的北极地区，也经历了高于正常水平的气温，这表明更广泛的极地区域可能经历了夏季最热的纪录，根据沃尔特梅尔的美国国家冰雪数据中心在科罗拉多州。

The results showed that mercury chloride (0.5 and 1.5mg/kg BW) had obviously toxicity to the liver and the kidney of mouse, and the dose of 1.5mg/kg BW could damage the ovary function and reduce the number of superovulation oocytes.The results also showed that mercury chloride could inhibit the extruding of the first polar body and affect the quality and the viability of mouse oocyte and reduce the rate of IVF,but little impact on germinal vesicle breakdown of mouse oocyte in vivo.

结果表明，0.5和1.5mg/kg BW汞对小鼠的肝脏、肾脏有明显的毒性作用，1.5mg/kg BW组还对卵巢有明显的毒性作用，并能显著降低超排卵的卵母细胞数；汞对体内卵母细胞生发泡破裂没有影响，但可以抑制卵母细胞第一极体的释放，影响卵母细胞的存活率并降低体外受精率。

The structure and strength of this meridional flow is believed to play a key role in determining the strength of the Sun's polar magnetic field, which in turn determines the strength of the sunspot cycles.

的结构和本经向流的力量，相信在确定太阳的极地磁场，从而决定了太阳黑子周期的力量力量方面发挥关键作用。

The bonding energy of the mixed covalent/metallic Ti-Al bond for the Ti-terminated Al/TiB_2 interface is larger than that of the polar covalent Al-B bond with partial ionic-like feature for the B-terminated interface. Metallic bond between Al atoms forms across the Al/AlB_2 interface, which results in weaker interfacial adhesion than that for the Al/TiB_2 interface. The interfacial energy for Al/TiB_2 depends on the interfacial chemical potential.

Al熔体中仅存在TiB_2粒子，而无多余溶质Ti时，α-Al在TiB_2粒子上异质形核产生的Al/TiB_2界面能大于α-Al从Al熔体中直接形核时的液-固界面能，不满足TiB_2粒子充当α-Al有效异质形核核心的能量条件，这从理论上解释了Al熔体内仅存在TiB_2粒子时无晶粒细化效果的实验现象。
