G$tx8wgw$m0 The cigarette has evolved much since its conception; for example, the thin bands that travel transverse to the "axis of smoking"(thus forming circles along the length of the cigarette are alternate sections of thin and thick paper to facilitate effective burning when being drawn, and retard burning when at rest.

香烟有很大发展,因为它的概念,例如,薄带的旅行横向的"邪恶轴心吸烟"(从而形成界沿长度的卷烟)的替代部分薄,厚纸板,以促进有效燃烧时制定,并延缓燃烧时,在休息。

At present, more screen varieties, the product is not uniform, but it is important to clear the screen mesh size and diameter determines screen of perforated and whee thickness, at the same time, influenced by the online photographic emulsions, hosting the content, obviously, perforated, the screen can be primary processing rough coated photographic emulsions in respect of this exposure time should also be the longer exposure time otherwise.

纲后,丝网品栽较众,产物参不差不齐,但有一点务必不合明,丝网的纲数与丝径不决着丝网的开孔率和网布薄度,同时,又感化着感平乳剂的网上驻留度,较着,开孔率不小、丝线不细的丝网可涂布的感平乳剂不离薄,所以曝平工夫也答相答加长,反之则曝平工夫缩长。

Thus the alkaline zincate continuous zinc plating technology for steel sheet was investigated, with the emphasis being placed on the effects of the bath composition and process conditions on the current efficiency. The throwing power of the plating solution was tested using Hull's cell 8 points thickness method, and the adhesion strength of the coating was examined by heating and shock cooling test.

为此,研究了用于薄钢板连续电镀的锌酸盐镀锌工艺,重点研究了镀液成分及工艺条件对电流效率的影响,用Hull槽8点法测试了镀液的均镀能力;用加热骤冷法测试了镀层的结合力,并对薄钢板连续电镀锌的前后处理工艺作了探讨。

Choice of materials for Q235, The choice program is stamping process Piercing blanking -- thinning Burring -- Wedge-bending -- U-shaped curve In this program of cost savings but also appropriate to increase production efficiency, use of this program will mainly involve the following four die : Punching blanking die;(2) thinning Burring die;(3) Wedge-bending modulus;(4) U-bending modulus.

选择的材料为Q235,选择的冲压工艺方案是冲孔落料--变薄翻孔--斜楔式弯曲--U型弯曲,此方案在节约成本的同时也适当的提高了生产的效率,采用此方案将主要涉及到以下四套冲压模具:(1)冲孔落料模;(2)变薄翻孔模;(3)斜楔式弯曲模;(4)U型弯曲模。

By analyzing the coupling between magnetic fields and accretion flows we get following results:(1) There should be an upper limit to the magnitude of magnetic field. Under such a case the disk remains Keplerian.(2) The observational distribution of effective temperature might be caused by magnetic diffusion.

对于磁化薄盘,我们的结果归纳起来是二点:(1)磁化薄盘应该有一个上限磁场,在这样的情形之下,磁化盘保持为开普勒盘;(2)观测上的有效温度的分布可能就是由于磁能的耗散而产生。

The results show that increasing the ball numbers and mandrel extension length may reduce the ovalization, but leads to more remarkable wall thinning; the ovalization becomes more severe with the larger bending angle; the smaller the relative bending radius, the larger the ovalization is; the ovalization and wall thinning degrees are both smaller in the case of pressure die with dry lubricant; and under the same bending condition, the ovalization of LF2M tube is larger than the one of 1Cr18Ni9Ti tube.

结果表明,增加芯头个数与芯棒伸长量都能减小弯管的截面畸变,但两者都导致弯管壁厚减薄量增大;随着弯曲角度的增加,截面畸变越严重,相对弯曲半径越小,无芯棒与芯头支撑段弯管的截面畸变愈严重;在压块无润滑情况下,弯管的截面畸变和壁厚减薄量都小,并且在同等弯曲条件下,1Cr18Ni9Ti弯管的截面畸变小于LF2M弯管。

Moreover some notations of Riemannian geometry we need in this thesis are given there.

第二章介绍我们所讨论的薄壳的数学模型,这些模型都是经典的薄壳模型,而它们是由位移方程的形式所给出的。

Accompany with the subduction of Pacific and Indian plates, upper mantle convected more violently, and new upwelling astheosphere replaced and eroded the lithosphere, and resulted in irregular thinning of cloud-like mantle along reticulated or dondroid weak zones. The thinning was dominated by replacement of lithosphere with new upwelling astheosphere, and accompanied possibly by delamination.

在这过程中,特别是伴随太平洋、印度洋板块的俯冲作用,地幔对流加剧,上涌的新生软流体顶蚀置换岩石圈,从而造成了沿早期业已存在的幔内薄弱带网络,出现类以&蘑菇云状&的地幔不规则减薄,这种减薄以新生软流体取代岩石圈为主,并可能伴随一定程度的岩石圈拆沉作用发生。

The physico-mathematical model was established by considering the variation of the apparent contact angle to describe the configuration of the total extended thin film region,including the equilibrium region,the interline region and the meniscus region.In addition,the ratio of disjoining pressure and capillary pressure was introduced to distinguish the film ranges of the different regions by considering the influence of film configuration,liquid property and channel size.
