Results (1)ATP could inhibit the proliferation of U937 cells with inhibition rate over 43% after 48hour ATP treatment;(2)ATP treated U937 cells numbers increased obviously in G1 phase,and apoptosis peak appeared before G1 phase,apoptotic cell number was 3.4% for 24hour,and was 22.7% for 48hour of ATP treated U937 cells;(3) Nuclear chromatin condensed into sperical masses bound cytoplasma membrane formed apoptotic bodies which is shed from membrane surface into intercellular medium;(4) Apoptotic bodies were nigrosine staining negtive.

结果 (1)ATP对U937细胞的增殖有按摩明显的阻抑作用，加药48h后增殖的抑制率可达43%以上；(2)ATP处理的U937细胞周期发生改变，G1期细胞数按摩明显增多，ATP作用24h时G1期前出现亚二倍体峰——凋亡峰，凋亡细胞数为3.4%，作用48h时凋亡细胞数增多为22.7%；(3)ATP处理的U937细胞首先在核内染色质浓缩成半月形贴近核膜，逐渐向核膜外移动，进入胞浆内再移向质膜内外面，紧贴质膜外面再逐步脱离细胞体，进入细胞基质中，成为游离的凋亡小体。

It begins off the east coast of Taiwan and flows northeastward past Japan, where it merges with the easterly drift of the North Pacific Current.

自菲律宾开始，穿过台湾东部海域，沿著日本往东北向流，在与亲潮相遇后汇入东向的北太平洋洋流。

In the orient young bulls are tested for the fight arena in a certain manner. Each is brought to the ring and allowed to attack a picador who pricks them with a lance. The bravery of each bull is then rated with care according to the number of times he demonstrates his willingness to charge in spite of the blade.

在古老的东方，挑选用于格斗的小公牛时，它们被带进场地，向手持长矛的斗牛士攻击，裁判以它受到攻击后再向斗牛士进攻的次数多寡来评定这只公牛的勇敢程度。

在古老的东方，挑选小公牛列竞技场格斗有一定的程序、它们被带进场地，向手持长矛的斗牛士攻击，裁判以它受激后再向斗牛士进攻的次数多寡来评定这只公牛的勇敢程度。

Each is brought to the ring and allowed to attack a picador who pricks them with a lance. The bravery of each bull is then rated with care according to the number of times he demonstrates his willingness to charge in spite of the sting of the blade.

它们被带进场地，向手待长矛的斗牛士攻击，裁判以它受戳后再向斗牛士进攻的次数多寡来评定这只公牛的勇敢程度。

The co-polarized and cross-polarized backscattering coefficients and polarizability of a layer of non-uniformly oriented metamaterial spheroids under illumination of an elliptic polarized plane wave are numerically simulated.

计算了任一椭圆极化入射下一层非均匀取向的随机分布异向材料粒子的同极化和交叉极化后向散射系数，以及随机粒子产生散射场去极化的极化度。

Meanwhile, Haiti, burdened by its post-independence isolation and the 100 million francs in payment it was forced to give France for official recognition, began its perilous slide toward turmoil and dependency, resulting in a 19-year US occupation and two subsequent interventions in the past 100 years.

而这段时间里，海地承受巨大压力：独立后的孤立无援加之必须向法国支付一亿法郎以换取法方的正式承认，它开始滑向动荡和丧失主权的危险境地，最终导致美国对它长达十九年的占领和其后一百年中两次入侵。
