反对称的

A better idea springs from the weak force , which governs certain nuclear processes, including radioactive beta decay. In 1964, physicists found that the weak force is not quite symmetrical in its dealings with matter and antimatter, resulting in something known as CP violation .

比较好的意见是后来突然提出来的称为"弱力"的理论，这种"弱力"控制了某些核过程，其中也包括了放射性的β衰变。1964年，物理学家发现弱力在处理物质和反物质是不完全对称的，此种结果称为宇称不守恒。

Using the seale separation method, the meso-scale structure of Mcc occ- ured near the Delta Area of the Pearl River is studied. It is shown that there is a meso-scale cyclonic circulation at 1000 hpa level and a meso-scale anticyclon at 200 hpa level associated with the Mcc. The axis of the Meso-scale cyclone center tilts northwestward with height, stretching up to 400 hpa level.

用滤波方法分析了一例发生在珠江口附近地区的Mcc的中尺度结构，结果表明，在对流层下部有中尺度的气旋性涡旋与Mcc相应，涡旋的中心轴线随高度向西北方向倾斜，在地面涡旋的上方200hPa层上，是一中尺度的反气旋性涡旋，中尺度的辐合中心和上升运动中心偏于Mcc的西部，扰动温度场也是非对称的，在对流层上部没有中尺度的暖高压。

And the distribution of the magnetic shear angles exhibits the hemisphere sign rule as the asymmetry of helicity. In our dataset, 53% of the active regions in the south hemisphere have positive shear angle and 62

磁场剪切角具有南北半球符号的反对称手征性，在南半球有53％的活动区的磁场剪切角是正的，而在北半球有62％是负的。

Fighting against insurance swindling is the duty of the insurance company and the whole society.

反保险欺诈是保险公司以及全社会的共同职责，我们应该化解保险市场中信息不对称的问题，强调最大诚信原则在保险法中的重要地位，并借助于国外的经验，采用相应的对策同保险欺诈行为作斗争。

Dentatus male (H1) were found to be viable, while the reciprocal hybrids from P. dentatus female and P. olivaceus male (H2) were completely inviable. All the H2 individuals showed morphological deformities and died before first feeding.

褐牙鲆和夏牙鲆正反交的活力是不对称的，褐牙鲆♀×夏牙鲆♂的正交杂种活力正常，能够正常存活、生长和发育，而反交夏牙鲆♀×褐牙鲆♂的杂种体态畸形，孵出后不久死亡。

The calculated results show that azido in azides has linear structure , the most optimized CaN6 has linear structure , and the most optimized (CaN6)n (n=2～5) clusters have chain structure of perpendicularity of approximate diamond composed by two azido with two Ca atoms . The middle N atoms of azido show positive, the N atoms at both ends of azido show negative, and the N atoms effected with Ca atoms directly show more negative . There is strong ionic bond between the Ca and N atoms. The IR spectra of the most optimized (CaN6)n (n=1～5) clusters have four vibrational sections , the whole strongest vibrational peak lies in 2195～2280cm-1,and the vibrational mode is anti-symmetric stretching vibration of N-N bonds in azido . Stability analysis show that (CaN6)3 and (CaN6)5 clusters are more stable than other clusters .

结果表明，叠氮化合物中叠氮基以直线型存在，CaN6团簇的最稳定结构为线型结构，(CaN6)n(n=2～5)团簇首先由两个叠氮基与两个Ca原子构成一个近似菱形，再由菱形相互垂直形成链状最稳定结构；叠氮基中间的N原子显示正电性，两端的N原子显示负电性，且与Ca直接作用的N原子负电性更强，金属Ca原子和N原子之间形成很强的离子键；(CaN6)n(n=1～5)团簇最稳定结构的IR光谱分为4个部分，其最强振动峰均位于2195～2280cm-1，振动模式为叠氮基中N-N键的反对称伸缩振动；稳定性分析显示，(CaN6)3和(CaN6)5团簇相对于其他团簇较为稳定。

Recently, the study on the QCD phase structure is extended to finite isospin density.

近年来，对QCD的研究已经扩展到有限同位旋密度的范围，而研究QCD在有限同位旋密度下的性质对调查致密星体、同位旋反对称核物质以及中能的重离子碰撞都有重要的意义。

Firms with fewer antitakeover provisions decrease the asymmetric information to the investors. The market quickly reflects the information and adjusts the stock price to equilibrium. Thus, better corporate governance has higher idiosyncratic risk. We can reduce the portfolio risk by included the well-governed portfolio.

公司治理好的投资组合因为资讯不对称的情况降低，所以其可分散风险较高也就是投资人会将得到的资讯迅速反映在市场上，因此如果在投资组合中纳入反并购条款少的公司，会使投资组合的风险降低。

The symmetry between matter and anti-matter implies that for every particle there exists an antiparticles with equal mass and opposite charge.

第二段：指出这一粒子观点是由迪拉克首创的，他的理论揭示了物质和反物质的基本对称。

With the character of CVC roll curve, the strip thickness distribution, rolling pressure distribution and pressure between rolls along transverse direction are calculated, by using the model of the real roll crown distribution and the character of the antisymmetry of mills. The results are in good agreement with production data.

根据CVC轧辊辊形的特点，采用实际轧辊凸度分布模型，并利用轧机的反对称性质，计算轧机垂直中心线一侧的板断面厚度分布、轧制力分布、辊间压力分布等，提高了板形计算和辊间压力计算的精度，模拟计算结果与现场数据相符。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
