With case-conetol metbod and statistic method 0f single factor and multi-variate stepwise fegression analysis, the RF of CHD and CAS bave been analysed and similarity and difference of botb diseases have been discussed. THE results revealed that kidney deficiency, heart deficiency, Liver deficiency, Lung deficiency, qi deficiency, senility index, bypertension, chronic bronchitis, diabetes, typerlipemia, obesity are principal RF of CHD.

调查内容涉及129个中西医因索，应用病例一对照的研究方法，以单因素分析，多元逐步回归对CAD和CAS的中西医易患因素进行比较分析，并探讨了二种疾病易患因素的异同点，结果表明：CHD主要易患因素是肾虚、心虚、肝虚、肺虚、气虚、衰老指数、市血压、慢支、糖尿病、高脂血症、肥胖。

In this thesis, the virtual boundary integral equation is based on double layer potential with the virtual density to be determined on virtual boundary. Since this integral equation related to double layer potential only involves the computation of the normal derivative and second normal derivative of fundamental solution, the exponential integral function is not involved in it, so numerical computation for the exponential integral function is avoid.

本文则基于双层位势，引入虚拟矩密度函数来建立虚边界积分方程，并首先对时间变量进行解析积分，在虚、实边界上采用常单元和等额配点离散，该方程只涉及含基本解的法向导数及其二阶法向导数项的计算，对时间变量进行解析积分后，不会出现对指数积分函数的空间变量的积分计算。

By introducing the concept of"nihility point"and the method of"spherule bounding" in the algorithm, we have simply and effectively realized boundary discretization in 3-D space.

这种算法采用"虚点"概念，按照一定的规则用"小球跳跃法"简单而有效地实现了三维场域边界的三角形离散。

He also proposed a method for vanishing point extraction called iteratively shrinking.

给出了求取虚点的迭代收缩技术。

The principle of the minimum potential energy Because the virtual displacement is very small, the value and the direction of the external forces can be regarded as invariable during the virtual displacement, and only its acting points are changed.

三 极小势能原理由于虚位移是微小的，因此在虚位移的过程中，外力的大小和方向可以当做保持不便，只是作用点有了改变。

Based on theoretical analysis to this modulation phenomenon, two sets of linealy equations for computing 3D displacement of the virtual point sources of the reference beams and the measured object have been derived.

基于对这种调制的理论分析，导出计算参考光虚点光源和被测物体三维位移的二个线性方程组。

For economy in drawing it is best to avoid pecked lines and diced filling.

为节省绘图时间，最好不用点虚线和虚点方格线。

Gangliosides antagonized the apoptosis induced by corticosteron, and the underlying mechanism is related to activiation of neuronal calcium signal cascade, promoting neurotransmitter release. Gangliosides also have an ability to promote the neuronal filopodia formation and may have a antidepressive-like neuroprotecive effect. 2. Theory study: We explained the clinical symptoms showed in the syndromes of deficiency of kidney-Yang and deficiency of kidney-Yin with modern scientific technical terms. Moreover, we supposed the location of kidney of traditional Chinese medicine may be in the hippocampus but not in the hypothalamus, which is also the centre of learning and memory.

鹿茸有效成分能够拮抗皮质酮诱导的神经细胞凋亡，其机制与影响钙信号途径、促进神经递质释放有关，鹿茸有效成分还能促进神经细胞丝状伪足生长，并且可能具有抗抑郁药样的神经保护作用。2、理论研究：用现代科学语言对肾阳虚证和肾阴虚证临床症状的病理生理机制进行合理的解释，提出中医肾脑相关理论实质假说，推测补肾中药的调控点应当在下丘脑—垂体—肾上腺轴的高级中枢海马，而非下丘脑。

He is the most remarkable man that I have ever known.

他是我知道的人中最值得注意的人。

Increased appearance of lymphocele was noticed in patients with diabetic nephropathy, congenital malformations of the urinary tract, and inflammatory diseases, including glomerulopathy and extraglomerular ones, after high-voltage radiotherapy and after removal of the renal graft.

经过高压放射疗法和切除移植肾后，在糖尿病肾病患者、泌尿系统先天性畸形患者和炎症患者身上发现淋巴囊肿有所增加，包括肾小球病和球外疾病等。
