On the basis of Nagumo′s existence theorem for the singular case, we obtain the existence of solutions of singular equations satisfying nonlinear boundary value conditions and periodic boundary value conditions by means of approximations.

在Nagumo型存在定理的基础上，我们应用逼近的方法给出了奇性方程满足非线性边值条件和周期边值条件的解的存在性。

In thesequel,the definition of singular point is given,and then the Laurent's expansionof a LR regular function with isolated singular points is obtained in the corre-sponding Laurent domain,after that,we introduce the definition of residue,andthe residue theorems are obtained.

虽然这仅仅讨论的是在Clifford分析中的较为特殊的Riemann边值问题与奇异积分方程，但它仍然改进了以前文献的结果，从而也为更进一步地解决Clifford分析中一般的Riemann边值问题与奇异积分方程提供了基本的解决思想。

Three years ago a survey of 2,000 families found that 20 per cent never have a sit-down meal, while 75 per cent of the rest eat while watching television.

三年前针对2000个家庭的一项调查发现，20%的的家庭从来没正式地用过餐，而其余家庭中的75%则边看电视边吃饭。

For some oil seal products, due to the complicated structure, we use the oil seal edge-trimming machine made in Taiwan to exscind the slitter edge, it is in the end of 2006 that we purchased this machine.

对一些油封产品，由于其结构复杂，我们采取废边切除的方法以满足产品要求，使用的设备是台湾生产的油封修边机，我们在2006年底购入。

It depends on three aspects: first, the safeness of the slope and ambience is ensured; second, use function of the slope is satisfied; third, the lowest cost of project.

一个设计方案是否合理主要取决于三个方面：第一是能保证边坡及周围环境的安全；第二是满足边坡的使用功能；第三是工程造价最低。

Root piles offer anti—slide and anchor function for slope,and chemical grouting can improve soil shear strength efficiently.

树根桩对边坡土体产生抗滑和锚固作用，而化学灌浆能有效地提高边坡土体的抗剪强度。

In slope projects,a definite function is unavailable to describe the trend of slope deformation due to the discontinuity and heterogeneity of rockmass material and incomplete knowledge to slope structure.

边坡工程中，由于材料的非连续性、非均质性以及对结构认识的不完全性，难以用确定的函数形式对边坡变形趋势进行描述。

"Bangs Chop Firewood" in two utilities to sing while develop, with the smart-alecky singing sound, the splendid performance the Hunan local opera lively, the lively style will display incisively, but "the Beijing Rhyme" danced the utilities with the specialized dancer's posture, the rich expression has splendidly unfolded the Chinese country play -- Peking opera charm.

刘海砍樵》里的两名小演员边唱边演，用俏皮的歌声、出色的表演将湖南地方戏的活泼、轻快的风格表现得淋漓尽致，而《京韵》舞蹈中的小演员们用专业的舞姿、丰富的表情更加出色地展现了中国国戏——京剧的魅力。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
