逐渐缩小的

This approach is base on the following idea:under not effect to the deformation of rectangular pipe,to change right angle to obtuse angle which is variant as some regular,make plain-barreled roll pass receive vertical roll shape pipe blank,and then let pipe blank entering into vertical roll pass.With continuous deformation, the difference between diagonal line of rhombus pass will be reduced to zero,finally changed into a square.

该方法的基本思路是：在不影响方矩形管变形的前提下，通过将孔型顶角由直角改为按一定规律变化的钝角，让呈卧菱形状的平辊孔型接纳呈立菱形状的管坯，接着让卧菱形状的管坯进入立菱形状的立辊孔型，随着变形的继续，逐渐缩小菱形孔型对角线之差直至为零，成为正方形。

With the reduction of SOM content and the elevation of contamination concentration, the difference between PHE and PYE decreases gradually, while B［a］PYE exhibits a significant difference from them. This could be attributed to the high lipophilicity and large molecular size of B［a］PYE, which make the molecule of B［a］PYE to be more easier to be held in the nanopores of clay and the dense region of SOM.

不同多环芳烃SPMD辅助解吸率差别很大，随着土壤有机质含量的降低，以及污染物浓度的提高，菲和芘的解吸差异逐渐缩小，而苯并［a］芘与上述2种多环芳烃的差异很大，主要是由于苯并［a］芘具有高度亲脂性，并且分子较大，造成其容易滞留在粘土的微孔及有机质的致密结构中。

Approximately 5% of subjects who had a perforation died within 14 days of the procedure. Risk of death was significantly increased by perforation after colonoscopy (OR, 9.0; 95% CI, 3.0 - 27.3) or after sigmoidoscopy (OR, 8.8; 95% CI, 1.6 - 48.5). The difference in risk between the two procedures has been narrowing because the risk of perforation from colonoscopy has decreased over the years, presumably from improvements in technology and in training.

约有5%发生肠穿孔的民众在筛检后14天内死亡，做完直肠镜或大肠镜后发生肠穿孔的民众死亡率明显增加（大肠镜：危险比，9.0；95%信赖区间，3.0 - 27.3；直肠镜：危险比，8.8；95%信赖区间，1.6 - 48.5），但这两种筛检方法的风险差异正在逐渐缩小中，可能是因为技术的改良与人员的加强训练，使得大肠镜的肠穿孔危险已逐年下降。

The intercourse problem becomes very important in the modern society as the extent of the intercourse is more and more wider and the object and the style of the intercourse is vertiginous along with the rapid development of the information industry.

尤其在现代社会，信息化的程度越来越高，人们的距离逐渐缩小，交往的范围越来越广，人们的交往对象和相互作用模式不断发生变化，交往问题对于现代社会显得尤为重要。

Research on Coal-forming Environment and Sequence Stratigraphy in Coal Measures Strata;2. The results show:1, there were the differences between the characteristics of the coalification between the Taiyuan Formation vitrain and the Shanxi Formation vitrain which were formed in differencial coal-forming environment s, and the differ.

结果表明：在高煤级煤早期阶段，形成于不同成煤环境的太原组煤与山西组煤的煤化特征仍有差异，在第三次煤化作用跃变之后这种差异逐渐缩小消失；高煤级煤分别以第三次和第四次煤化作用跃变为界，呈现出阶段性演化的特征，每阶段的演化机理有所不同；第三次煤化作用跃变中大分子结构的演化以芳构化作用主为，第四次煤化作用跃变则以强烈的环缩合作用占优势。

Naturalists are concerned that diminishing wetlands are leading the water birds to overpopulate this refuge.

自然主义者担心沼泽地的逐渐缩小会使这个保护区的水鸟密度过大，超出此地的承受能力。

The inequality of housing consumption distribution between tenures has significantly been reduced.

住宅消费分配不均的情形则有减少的趋势，此一现象隐含著不同权属间的住宅品质差距已逐渐缩小。

The difference between china poultry industry and international standard is becoming smaller and smaller in breeder,disease control,nutrition and technique after rapid development in china ,but the difference is still big on poultry house environmental control,The effection of house environment improvement on chick health and performance is overlooked . Poultry house environmental control is becoming more and more important in poultry industry.

随着近年来养鸡业的迅猛发展，目前我国在品种、营养、疾病控制和饲养技术方面与国际先进水平的差距逐渐缩小，但在环境控制方面还存在着很大的差距，环境控制对家禽生产的影响一直没有得到应有的重视，在国内目前基本解决了家禽良种引进、烈性传染病控制、营养和饲养技术等问题的前提下，鸡舍环境控制在家禽生产中起着非常重要的作用。

Upside-down taper extracting tank is very beneficial to the circulative extraction from downwards to upward, through the water dividing board and sieve specially designed at the tank bottom, the extracted solvent can make upward movement evenly from the tank bottom. As the tank volume gradually decreases from the tank bottom to the tank top, the short circuit during the flow of solvent can be avoided. Upside-down taper extracting tank is the ideal upgraded equipment for the technology requiring the realization of dynamic extraction processing.

倒锥型提取罐对溶剂的循环提取极为有利，当提取溶剂从上到下循环提取时，通过罐底专门设计的分水板和筛网，提取溶剂能够均匀地从罐底部向上运动，而且由于从罐底部向灌顶部逐渐缩小，所以能很好的避免溶剂流动时短路现象，对于需要实现动态提取加工的工艺而言，倒锥型提取罐是极为理想的升级换代设备。

Certain types of sockets are ''connectionless'', most commonly

某些类型的套接字是无连接的，大多数是UDP协议。
