After getting these four line-of-sight vectors, we inverse these data in special observation coordinate based on space analytical geometry, then we can get the vector that has three components on every coordinate, this vector will be treated as the total wind profile in the three-dimensional observation field, the result of this four-point method can basically reflect all the spatial and temporal variation of the atmospheric wind.

在得到视线方向风速矢量后，从选定的三维观测坐标系对这四个矢量进行空间解析几何的运算，可得到观测坐标系的各坐标轴上四个测量矢量的各坐标分量的标量和。从而以这个在三个坐标轴上都有分量的矢量作为在观测视场内的总的风场的风速矢量。

The discussion includes two parts: the colonizer and the colonized. In the case of the colonizer, the interrelations between ethnicity, history, empire, and war is explored.

The expression level of metabolitic enzyme (CYP1A1, CYP1B1) and its correlation with cell differentiation /apoptosis were studied as well. The influence of resveratrol in cell cycle was determined with FCM. Results 1 Resveratrol not only suppresses the growth of medulloblastoma cells in a dose and time related fashion but also induces cell differentiation and apoptosis. Resveratrol promotes differention of UW228-1,-2 cells to forward glia, UW228-3 and Med-3 cells to neuron. A treatment of resveratrol in the concentration of 100μM for 48hrs comit most of cells die of apoptosis. 2 Among the four cell lines Fas and Caspase-3 were constantly expessed, whereas FasL was absent irrespective to the drug treatment. 3 ICC, RT-PCR, Western-blot hybridization and EROD enzymatic activity assay demonstrated that expression of CYP1A1 is different after treatment with resveratrol in four cell lines, up-regulated in three UW228 cell lines in a dose dependent manner but down-regulated in Med-3 cells. Suppressive effect of resveratrol on CYP1B1 expression is the same among four medulloblatoma cell lines. 4 Cell cycle distribution of UW228-3 was greatly changed after treatment.

结果：1、白藜芦醇以时间和剂量依赖性方式抑制髓母细胞瘤细胞生长，同时促进细胞的分化和凋亡：白藜芦醇促使UW228-1、-2靶细胞向神经胶质细胞方向成熟分化，UW228-3、Med-3细胞向神经元细胞方向成熟分化，以100μM作用48小时效果显著；2、四个细胞系均有Fas和Caspase-3表达，但无Fas-L基因表达和蛋白活性产生，因此难以形成Fas相关性死亡通路；3、白藜芦醇处理前后CYP1A1基因的表达在各细胞系略有不同：UW228-1，-2，-3三个细胞系白藜芦醇以剂量相关性方式上调CYP1A1的表达，而Med-3细胞系，白藜芦醇却抑制CYP1A1的表达；四个细胞系在白藜芦醇处理后CYP1B1的表达均受到抑制；4、UW228-3细胞系经白藜芦醇作用后细胞周期有较大改变，表现在G0/G1期在整个细胞周期中所占的比例增加，而其它时期则相应减少。

The purposes of this study were:(1) to explore the relationship among students' cognitive and conation variables,(2) to explore the effect of cognitive/conation variables on students' learning performance, and (3) to group observations into clusters by cognitive/conation components.

本研究的目的如下：(1)了解四个认知成份变项与四个意动成份变项之关系。(2)探讨八个认知╱意动成份变项对国中学习表现的预测力。(3)探讨认知╱意动成份是否能将受试者区分成明显的集群。

It was crazy. For the first three or four weeks of the season I was pitching with four rookies and a couple of them are now in Double-A. We just had a bad run of health.

在这一季的前三到四个礼拜，我上场投球，带著四个菜鸟，其中有二个现在正待在2A，我们只是有一个很糟糕的开季伤兵问题。

Their sound, and their broad repertoire of traditional folk material and topical songs inspired other groups such as the Kingston Trio (founded 1957 ), the Chad Mitchell Trio , New Christy Minstrels , and the "collegiate folk" groups such as The Brothers Four , The Four Freshmen , The Four Preps , and The Highwaymen .

他们的声音，他们的许多传统民俗的物质和热门歌曲的灵感等群体金斯敦三重奏(创建于1957年)，乍得米切尔三人，新christyminstrels，和&合议民俗&群体，如兄弟四个，四个年级，四preps和

When using Swiftmend it is important to note that if one of thetanks is spiked while the Druid is reapplying Lifeblooms, the Druidshould then Swiftmend as the third spell, and reapply Rejuvenationwith the fourth spell. Likewise if a raid member falls near deathduring Lifebloom reapplication, the third and fourth spell can beused to place a Rejuvenation on them followed immediately by aSwiftmend.

关于使用迅捷治愈法术，很重要的一点是在等待叠加或刷新生命绽放时关注tank的血量，如果tank受到很严重的伤害，这时循环的第三个法术施放迅捷治愈而第四个法术补回春，同样的，如果一个raid成员在你补生命绽放的过程中濒临死亡，第三个和第四个法术用来上回春并迅捷治愈(老外闭口不提自然迅捷？)。

These four points, where the Seine intersected the wall of the capital, the Tournelle and the Tour de Nesle on the right, the Tour de Billy and the Tour du Bois on the left, were called pre-eminently,"the four towers of Paris."

塞纳河把京城的城廓切成四个点，左岸为小塔和纳勒塔，右岸是比利炮台和树林炮台，这四个点被誉称为巴黎四塔。

Finally, we combine all the subprograms, along with graphical user interfaces, to complete the program. To obtain circle and center points, we use graphical methods in three-position problems and vector loop methods in four-position problems.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it.
