文章主要介绍作者在三维图形系统GP3D的设计开发中，以矢量代数的方法对三维图形元素作直接旋转、平移等变换，生成复杂的组合图形，并以旋楼梯的线框图造型进行验证。

Land-sea heating, monsoon circulation, eastern Pacific trade wind and the slow seasonal shift of NE Pacific SST form winter to summer bihemispherically- all in joint action give rise to the enhancement of the Walker circulation that will travel east-and northward (west-and southward); the intensification of the maintained eastern Pacific Hadley circulation and north America-Alatantic Walker circulation zonally is responsible dominantly for the zonal/meridional movement of the WPSH in the winter-to-summer (or summer-to-winter) shift and its combination with the north American subtropical high.

海陆加热、季风环流、东太平洋信风以及东北太平洋海表温度由冬向夏关于赤道南北季节转换的迟缓性等综合作用导致的纬向Walker环流的加强东移和北抬、持续的东太平洋Hadley环流和北美—大西洋纬向Walker环流的加强是西太平洋副高由冬向夏产生东西、南北移动及其与北美副高合并的主要原因。

Hitherto, the explanation for this shift from the smaller skulls and wider pelvises of man's apelike ancestors has been a shift from a vegetable-based diet to a meat-based one.

至今，这种从人类类猿祖先的小颅骨和宽大骨盆到现在的改变被解释为一种草食到肉食的改变。

Hitherto, the explanation for this shift from the smaller skulls and wider pelvises of man's apelike ancestors has been a shift from a vegetable-based diet to a meat-based one.

迄今为止，对人类从拥有较小头骨和宽大骨盘的类猿祖先进化至直立人原因的解释认为这是由于饮食习惯发生改变造成的，直立人已经从素食转变为肉食。

Hitherto, the explanation for this shift from the smaller skulls and wider pelvises of man's apelike ancestors has been a shift from a vegetable-based diet to a meat-based one.

而比直立人再早的类猿人的则是小头骨，宽骨盆。

For low molar ratios of Al/Zr, a hypsochromic shift of the initial catalyst absorption band, corresponding to the monomethylation of the catalyst, was observed. Further addition of AlEt2Cl was accompanied by a continuous bathochromic shift of the maximal wavelength corresponding to the formation of more dissociated ionic active species. Then, there would be a coordination of monomer to the ionic active species.

结果表明，无论是AlEt_2Cl还是MAO，少量的助催化剂首先使催化剂发生单烷基化反应，主催化剂金属中心的最大吸收峰波长发生蓝移，而当助催化剂量进一步增加时，金属中心的最大吸收峰波长红移，单烷基取代的催化剂被大量的助催化剂夺去电子成为缺电子的阳离子活性中心，以便烯烃单体的配位插入。

The results have indicated that the introduction of electron-donating methoxy or electron-withdrawing cyano-group at the 7-position of 3-phenylcoumarins caused a bathochromic shift for both absorption and fluorescence spectra. The phenyl group at the 4-position derivative has a hypsochromic shift for both absorption and fluorescence spectra.

结果发现，在3-苯基香豆素的7-位引入给电子基团甲氧基或吸电子基团氰基均使它们的吸收光谱和荧光光谱产生红移，4-苯基香豆素的衍生物的吸收光谱和荧光光谱均产生蓝移。3-苯基香豆素衍生物与4-苯基香豆素的衍生物的基态和激发态的电子转移方向相反。

Till now, there are a lot of generators such as the classical Fibonacci method, mid-square method, linear congruential method, feedback shift register method and combined method; the recent nonlinear congruential method, decimal fraction method, add-with-carry and substract-with-borrow methods, generalized feedback shift register method and MT method, and so on.

至今关于随机数发生器有很多的理论和方法，其中除了传统的Fibonacci法、平方取中法、线性同余法、位移寄存器法和组合方法；最近还有非线性同余法、取小数法、进位加和错位减法、广义反馈位移寄存器法和MT法等等。

The IR result shows that conjugative effect is the reason for the red shift of stretching vibration frequency for carbonyl, meanwhile hydrogen bonds lead to the red shift of stretching vibration frequency for hydroxy groups.

红外振动光谱结果发现，共轭效应导致了羰基伸缩振动频率红移，氢键的存在导致了羟基伸缩振动频率红移。

Have start, have shift gears, have cheer, have turn shift gears, forthright firm walks, also cragged shakes.

有启动，有换挡，有加油，有转弯换挡，有直路狠踩，也有坎坷的摇摆。

I had a lovely dog named PiPi, he was one of my best friends.

我曾经有过一只小狗，它的名字叫皮皮，它很善良，它是我最忠实的朋友。

Newly ovulated mouse oocytes were cultured in the CZB medium supplemented with different concentrations of pyruvate before treated for activation or assayed for MPF activity.

我们猜测卵母细胞在不含丙酮酸的条件下老化的更快，并且卵丘细胞可能通过消耗不含葡萄糖的CZB中的丙酮酸从而促进卵母细胞老化。
