天顶点

If, for example, you major in‵mathematics, you're going to wander into class one day ｜and the professor will say:①"Define the cosine integer｜of the quadrant of the rhomboid ‵binary axis, and extrapolate your result to five significant vertices."

例如，你主修数学，一天，你闲逛着走进教室，老师说：①"请定义菱形二元坐标象限的余弦积分，并将结果推广到五个有效顶点的情形。"

The selected musicians, ranging from ages 17 to 55, will participate in three days of master classes and rehearsals next month, culminating in an April 15 concert at Carnegie Hall conducted by Michael Tilson Thomas, the San Francisco Symphony's music director.

经过千挑百选的乐手年龄在17到55岁之间，他们下个月将参加3天大师主讲的讲习班及彩排，并於4月15日在卡内基音乐厅由旧金山交响乐团音乐总监汤玛斯指挥公演达到顶点。

The Cry1Ac5 domainⅢhas a distant relationship with other Cry1 proteins and its longβ18-β19 loop possesses a unique tryptophanat residue 544 and a unique asparagineat the loop apex(residue 546),as well as two consecutive serinesfrom residue 547 to 548.Alanine scanning mutations within the loop were initially generated and all mutants could produce bipyramidal crystals and express 130 kDa protoxins.

利用Swiss-Model服务器和Swiss-pdb Viewer软件建立了Cry1Ac5蛋白的三维结构模型，并利用Clustal W和DS ViewerPro软件对比分析了其与其它Cry蛋白之间的差异，发现Cry1Ac5的结构域Ⅲ与其它Cry1蛋白的亲缘关系较远，其结构域Ⅲ上的β18-β19 loop比Cry1Aa、Cry2Aa、Cry3Aa和Cry4Aa蛋白对应的loop长，其组成的残基中色氨酸(W544)、连续的丝氨酸(S547、S548)和loop顶点的天冬酰氨(N546)在Cry蛋白中都是独特的残基分子成分。

But the only zones in which the moon passes the zenith, the point directly over the head of the spectator, are between the twenty-eighth parallels are the equator.

但是，月亮经过天顶点，也就是说它能够爬上观测者的头顶的地方，必须位于地球赤道和南北纬二十八度之间的地带。

Venus will appear to arise from the pyramid's apex on that day, while an astonishing cosmological alignment of the earth, sun and the plane of the galaxy takes place.

金星将出现产生于金字塔的顶点在这一天，同时拥有惊人的宇宙对准地球，太阳和飞机银河发生。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
