In this thesis, we study some classes of holomorphic mappings in several complex variables, and obtain the estimations of some order item coefficients of homogeneous expansion for starlike mappings, close-to-starlike mappings and spirallike mappings relative to A .

本文对多复变数的几类全纯映照族进行研究，给出了星形映照，近星映照与相对于A的螺形映照的齐次展开式的估计。

Geometry quality for these mappings can be obtained from these inqualities,and some sufficiency conditions for starlike mappings and spirallike mappings are given.

本文建立了多复变数单位球上全纯映照的一些偏微分不等式，由此可映照本身的一些几何性质，并得到星形映照和螺形映照的充分判别条件。

Geometry quality for these mappings can be obtained from these inqualities, and some sufficiency conditions for starlike mappings and spirallike mappings are given.

由此导出全纯映照本身的一些几何性质，并得到星形映照和螺形映照的充分判别条件。

The zooplankton was mainly contributed by copepods, and its dominant species were mostly eutrophication indicators: Keratella cochlearis, Polyarthra trigla.

水库的主要优势种为轮虫，而且优势种所出现的种类多为富营养化指示种，如：螺形龟甲轮虫Keratella cochlearis、针簇多肢轮虫Polyarthra trigla。

The special screw is manufactured with the molding method and non-instantaneous envelope method on the numerical control millers generally.

异形螺杆的加工一般采用成型法及无瞬心包络铣削方法在专用数控铣床上进行。

With the continuous drive of the screw, the liquid will press from a seal cavity to another cavity in a spiral manner until it is pressed out of the pump body finally.

随着螺杆的连续传动，液体以螺旋形方式从一个密封腔压向另一个密封腔，最后挤出泵体。

In this way, the formation of a groove it ABCDEA "∞" shape of the seal space (such as single-head screw, the axial groove to Shun Rao screw plate to the mouth through the smoke emission and can not form a seal).

这样，凹槽ABCDEA也就组成一个&∞&形的密封空间(如采用单头螺纹，则凹槽将顺轴向盘饶螺杆，将吸排口贯通，无法形成密封)。

In this way, also the formation of a groove ABCDEA "∞"-shaped seal space (such as single-head screw, the groove will shun Rao axial screw plate to the mouth through the suction row, unable to form a seal).

这样，凹槽ABCDEA也就组成一个&∞&形的密封空间(如采用单头螺纹，则凹槽将顺轴向盘饶螺杆，将吸排口贯通，无法形成密封)。

In this way, the formation of a groove it ABCDEA "i" shape of the seal space (such as single-head screw, the axial groove to Shun Rao screw plate to the mouth through the smoke emission and can not form a seal).

那样，凹槽ABCDEA也便组败一个&i&形的密封空间(如采取双尾螺纹，则凹槽将逆轴向盘饶螺杆，将吸排口贯通，无奈构成稀封)。

Is the larger size of the domestic production of professional Cone, Ping-shaped single and double barrel screw the machinery manufacturing enterprises.

是目前国内较大的规模化专业生产锥、平形单、双机筒螺杆的机械制造企业。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
