It is proved that a semiring is complemented if and only if it is a direct product of some Boolean algebra and Boolean ring by studying the relations of congruences on the complemented semiring, so the complemented semiring is the commutative semiring.

s-内射模。通过研究可补半环S的性质及S上的同余关系，证明出可补半环与布尔环和布尔代数的直积是等价的，因而可补半环是交换半环。

根据实验数据绘制出电子密度分布的酪氨酸分子模型，它后面的仪器就是麻省理工学院的一台X射线衍射仪。

In chapter 3 of this work, we made some improvement on the base of original work and proposed a double exposure multi-beam interference method to fabricate a hexagonal lattice with irregular columns.

在以前的工作中，我们曾使用衍射分束器件得到三束呈伞状对称的光束相互干涉，制备出了对TE和TM两种模式同时具有较大带隙的二维三角结构光子晶体。

Prayer may be oral or mental, occasional or constant, ejaculatory or formal. It is a "beseeching the Lord"(Ex. 32:11);"pouring out the soul before the Lord" 1 Sam.

祈祷可能会口头上或精神上的，偶尔或经常，射精管或正式的，它是一个" beseeching勋爵"（出埃及记32：11 ）；"浇筑出来的灵魂，在耶和华面前"

After theoretically modeling,experiments were carried out to measure a CW laser modulation spectrum generated by a diode laser and an EOM device with the proposed method.

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
