模态

And the DOM and the transmission mode were calculated and simulated by the popular density calculation method and the characteristic matrix.

对模密度和光的传播模式分别用流行的光子能态理论和光学传输矩阵进行了计算和模拟。

Schauengurg[2] considered more general case and found necessary and sufficient conditions for the cosmash product coalgebra H Q to be a Hopf algebra with a Hopf subalgebra H and a weak projection !

Schauenburg在文献[2]中把Radford的研究加以推广，给出了使余smash积HQ为Hopf代数，H为HQ的子Hopf代数，且具有弱投射π：HQ→H(即π是左模余代数同态，且π|_H=id_H)的等价条件。

In strictly, it is hard to make the light normal incident into the sphere, double refraction will take place in crystal sphere when a TEM〓 mode Gaussian beam oblique incident into the sphere, and the two orthogonal polarized beams are both elliptical Gaussian beam. The ellipticity and eccentricity of the elliptical Gaussian beam will change with the incident angle, and for a fixed incident angle, they will change with the shifting of incident beam waist position.

由于严格意义上的正入射较难实现，基模圆高斯光束斜入射晶体球后将在球内产生双折射，且球内偏振态正交的两束折射光都将是椭圆高斯光束，它们的椭圆度e和偏心度Δ随入射角的改变而改变，在入射角一定的情况下，入射光束束腰的移动也将改变这两束折射光的椭圆度e和偏心度Δ。

Finally, sufficient and necessary conditions for endomorphism rings of some special modules to be semi-π-regular are given.

最后，我们对半π正则环作了一定的研究，给出了一个直投射模的自同态环是半π正则环的充要条件。

We give a theorem for the stable range of endomorphism rings of finitely generated projective modules over a formal triangular matrix ring T when T is an exchange ring.

2.6节对有有限exchange性质的形式三角矩阵环T给出了有限生成投射T-模的自同态环有稳定度n的一个具体关系。

Finally, it is proved that any semimodule over complemented semirings must have a ζ_s-injective hull and the complemented semiring must be the rPP semiring and the endomorphism semiring of every principal right ideal is still complemented semiring.

最后指出任一可补半环上的半模必存在内射包络、可补半环必是rPP半环且对于可补半环的任一主右理想的自同态集仍是可补半环。

The equivalent form for the PI regulator in stationary form is deduced and a resonant link is proposed.

最后分析了旋转坐标系下能实现稳态无静养的比例积分器在静止坐标系下的等效形式，提出包含单次谐波内模的谐振控制器。

When the power supply operates under standby mode, a Fly-back converter is used to provide standby power (5V/1.5A).

当电源模组在待机态时，使用返驰式转换器提供5V/1.5A 待机电源。

In particular, the homomorphism is splitting if P is quasi-n-tilting.

特别地，当P是拟-n-倾斜模时，这个同态是可裂的。

It is proved by the analytical and numerical method that the modulus of the Z transform of a finite impulse response sequence has no extreme values at poles (with maximums along imaginary axis and no extreme values along real axis), and the negative second order derivative of the modulus normalized along frequency axis with respect to angular frequency has maximums at the poles.

根据实测瞬态电磁脉冲响应，较好地反演了导体球和导体长椭球的冲激响应，测得了它们的雷达截面和谐振频率。用解析与数值相结合的方法证明了有限冲激响应序列Z变换的模在极点无极值（沿虚轴有极大值，沿实轴无极值），而沿频率轴的归一化值对角频率的负二阶导数在极点有极大值。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
