异性

Area coordinates and general Duffycoordinates are employed to transform the singular integrals of the Time-Domain Electric Field Integral Equation into non-singular integrals, which can be accurately and efficiently evaluated by dividing the transformed domain of integration into sub-domains.

摘要该文首先利用参数坐标和广义Duffy坐标变换将时域电场积分方程的奇异性积分转换成非奇异性积分，然后根据时间基函数的特点将该积分转换成可以快速精确计算的分区域积分。

In the last part of the paper, we construct a family of 2 parameter cubic algebraic curves interpolating two given endpoints and two given tangent lines and two given curvatures at these two endpoints with different initial cases in detail.

引 言三次参数曲线在计算机辅助几何设计与计算机图形学领域一直扮演着十分重要的角色，这主要是由于三次参数曲线是具有奇异性的次数最低的曲线，这些奇异性包括尖点、拐点和闭圈。

If heterosexuality is normal, why are so many mental patients heterosexual?

如果异性恋正常，为什么如此多的精神病人是异性恋者？

Plane strain, mode I quasi-static steady state crack growth is investigated utilizing the finite element method. It is once again established that TNT plasticity can significantly increase the stress level near the crack tip. The crack tip stress singularity is higher than or equal to the square-root singularity of elastic K field and is also independent of the plastic hardening exponent.

采用有限元方法研究了平面应变Ⅰ型准静态的稳态裂纹扩展，再次证实TNT非局部理论能够显著提高裂纹尖端附近的应力水平；裂尖应力场的奇异性超过或等于弹性K场平方根奇异性，而且与塑性硬化指数无关。

The researchers designed an experiment to test three possibilities: that males establish social dominance by mounting other males, that males who mount other males gain practice for later sexual encounters with females, and finally, that mounting males transfer sperm onto the other males, who then inadvertently inseminate a female with it later on.

研究人员设计了一个实验，测试雄性攀爬到其他同性身上的三种可能性：一、为了确立自己的社会主导地位；二、为以后同异性交配进行预演；三、排在雄性身上的精液可能会使稍后与之接触的异性意外受孕。

Results show that men and women evoke more jealousy when partner have an intimate body contact with an interloper than have a chat.

2在提示的十一种情境中，男性或女性皆较在意伴侣与异性较亲密的肢体接触，较不在意伴侣与异性的聊天行为。

Prof Lee Ellis and colleagues at Minot State University, North Dakota, traced the mothers of more than 5,000 American and Canadian students and members of gay and lesbian support groups, looking for links between prescription drugs taken during pregnancy and the sexual orientation of their children.

研究人员发现，女同性恋者的母亲在怀孕期间服用合成的甲状腺药物的几率至少是异性恋母亲的5倍，服用含有安非他命的减肥药丸的几率是异性恋母亲的8倍。

One is for Green's function in elements by using linear integrals; the other is for its normal derivative by the divergence theorem.

作法是仅需对原有的奇异性核函数加入一项使其异性消除，同时再将函数的解析积分值减去原方程式。

It is in this background that the displacement formula of flattened Brazilian disc for orthotropic material is proposed.

改进后的平台巴西圆盘克服了集中力产生应力集中的缺点，正交异性材料则是对各向同性材料的推广，在这样的背景下提出正交异性巴西圆盘试样的压缩位移公式。

According to the orthotropy and characteristics which have an extremevalue probably also in the region of 0—90°with respect to the rolling dire-ction of an orthotropic metal sheet,besides 0°and 90°,a model describing theanisotropic pattern of mechanical properties of an orthotropic metal sheet un-der uniaxial tension is developed by this paper.

本文依据板料异性性质的正交性，以几种符合正交特性的函数对一些材料的试验数据进行了拟合和对比，并与现有的异性模型进行了比较。结果表明，以形式为 A=A？

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
