Screen version of the seihan process is relatively simple: the first thing to liquid water-based emulsion coating of print to screen all blocked, and then set of print-and-drop to a drying oven; in the seihan, the renderer.draw business card printing and membership card making image transparency around sensitibvity too sensitive emulsion silk-screen version 5.1, and UV light sources on its exposure (because the screen typically drum-shaped, they need to be rotated screen drum).

丝网版的制版工艺也比力独一：首不后要用固态的火基型感平乳剂涂覆丝网版，以不通功所有的网孔，然后不兵丝网版不收到潮湿箱洋潮湿；制版时，不兵带有制卡和会员卡制作图像的正片环绕在涂覆功感平乳剂的丝网版滚筒上，并用UV平源不对其曝平（由于丝网印版凡是是滚筒状的，不陈必要回旋扭转网版滚筒）。

When we face the same problem, first of all we need make some observation from a number of companies from the basic level, Cross-ownership itself and the legal relationship which affect the substance of it without anyone in modern society showing the infinite complex patterns and without autopsying various forms of causes of the result, its formation methods, the variety of functions and social impaction.

在我国面临同样的问题时，我们有必要首先从公司法学的若干基本层面对其作一番观察，把握相互持股公司本身及其牵动的法律关系的实质而不必穷究它在现代社会中呈现出的无限的复杂形态，也无需解剖各种形态的相互持股之所以产生的原因、形形色色的形成方法、种类繁多的功能和社会影响。

Matthew 26:17 says,"And on the first day of the Azymes"; Mark 14:12,"Now on the first day of the unleavened bread, when they sacrificed the pasch"; Luke 22:7,"And the day of the unleavened bread came, on which it was necessary that the pasch should be killed".

马修26：17说，&就在第一天的azymes &；大关14：12 ，&现在起，就在第一天的未经发酵的面包，当他们牺牲了pasch &；卢克22时07分，&与天无酵面包来了，对那些有必要指出pasch应该被杀死&。

So, since I am trying to write a theoretical work about poetry, it behoves me to emulate their learned works of poetic doctrine.

所以，当我力图写一部关于诗的修辞论著时，我有必要去效仿那些博学的诗学著作。

Reefs, reef-mounds and lime mud mounds are all carbonate buildups, and the reefs and banks are important targets for petroleum exploration The reefs, banks and mounds should be divided from each other not only in theory, but also in exploration practice, because of so many differences in sedimentary compositions, fabrics, environments, distribution in time and space, and the characteristics of petroleum geology If the original reef or bank itself was fine reservoir rocks, then it would become a better reservoir after the reservoirconstructive diagenesis The formation of a high quality carbonate reservoir is controlled by two factors: the sedimentary microfacies and the reservoirconstructive diagenesis The first is the basis for the formation of a high quality reservoir, and with the high energy reefbank facies as the best; the latter includes the cataclasis, the dolomitization and the karstification The dolomitization and karstification are the best for the formation of a high quality reservoir The karstification has the widest distribution, profoundest effect, and plays a vital role in the high quality reservoir forming The karst types are quite rich in the limestone reef or bank reservoir, including synsedimentary karst, penesedimentary karst, supergene karst and hydrothermal karst, and so does the dolomitization reef or bank reservoir The formation mechanism of synsedimentary karst and penesedimentary karst is related to the short time exposing and leaching of the cyclical highfrequency shallowupward sequence when the reefs or banks are forming The supergene karst is controlled by the exposing and leaching of tertiary cyclic sequence type I interface after the reefs or banks forming Thus, there developed a great deal of secondary corrosion pores, corrosion fractures and huge caves besides some original pores remained in the reef and bank reservoir Scarcely there are any original effective pores in reefmounds and lime mud mounds, especially in senkes among mounds, but secondary pores could be formed by karstification, and there would likely develop source rocks with high organic abundance

礁、礁丘、丘同属碳酸盐建隆，礁、滩是重要勘探目的层。但各自在沉积组分、组构、环境和时空分布，以及油气地质条件上迥然不同，因而无论从理论还是勘探实践上，都有必要将其各成体系划分开来。礁滩自身为好储集岩，当建设性成岩作用叠加后可形成好的储层。碳酸盐岩优质储层形成，主要受沉积微相与建设性成岩作用两大因素控制。前者是基础，并以高能的礁滩相带为最好；后者主要包括破裂、白云石化和溶蚀三大类，并以白云石化或溶蚀为最优，其中的溶蚀分布最广泛、影响最深刻而对优质储层形成起决定性作用。礁滩储层中的古岩溶类型最为丰富多彩，包括同生期、准同生期、表生期和埋藏期热流体岩溶的所有类型，白云岩化礁滩体也不例外。其中，同生准同生期岩溶的形成机制与礁滩沉积时高频层序旋回向上变浅序列的短暂暴露淋溶有关，表生期岩溶则受控于礁滩沉积后三级层序旋回Ⅰ型界面的暴露淋溶。由此，导致礁滩储层中除了可以也是唯一保存原生孔隙外，还发育了次生溶蚀孔洞缝和大型溶洞。礁丘、灰泥丘尤其是丘间洼地中发育高有机质丰度烃源岩；它们自身没有有效的原生孔隙，但岩溶作用可以形成次生孔隙。

It is worth noting that among Aron's favorite terms of commendation were "prosaic" and its cognates, while he consistently used "poetry" and its cognates pejoratively.

有必要注意到阿隆最喜欢用&平凡无奇&之类的词语来表示赞扬，而当他用&诗意&之类的词语时则往往语含贬义。

With smart grids there should be no need to send out lorries and ring doorbells when the power fails.

有了智能电网，停电事故发生时，就没有必要派出维休车辆，敲别人门铃。

With smart grids, there should be no need to send out lorries and ring doorbells when the power fails.

When dealing with this kind of commercial banks, the CBRC shall take into account the external factors comprehensively, and shall take other necessary measures.

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
