Original image on the image by ultraviolet irradiation in corrosion-resistant membrane (on the printing plate cylinder electrodeposit to the membrane corrosion) or carbon paper, the membrane to the drum, in lukewarm water, carried out by chemical etching with ferric chloride, resulting in the depth of the screen.

原版上的图像经紫外线照射成像于耐蚀膜（对印版滚筒镀层进行腐蚀所用的膜）或碳素纸上，再将此膜包裹于滚筒上，在温水中显影，通过氯化铁进行化学腐蚀，形成深浅不一的网孔。

In some cases, its epimer 4 was also obtained. 22 compounds were synthesized, among them 18 were new.3. Using the intramolecular Pictet-Spengler reaction to form the pentacyclic skeleton of Et-743, the byproducts 25 were obtained under various conditions. The structures of them were determined to be 1, 2-dihydro-isoquinoline compounds, and the mechanism of the reaction was proposed.B. The synthesis of the analogs of Et-743Because of the failure of removing the protective groups in compounds 14, the synthetic strategy was adjusted.

对于苄基保护的羟基化合物13a，顺利得到化合物30，然后与不同的羧酸反应得到18个酯化合物33-50；对于苄氧羰基保护的氨基化合物13b，由于脱除保护基的化合物31在空气中不稳定，所以我们采取不经分离纯化，直接与羧酸反应得到酰胺化合物53-62，然后再分别对其C-21位的羰基进行还原氰基化，得到10个酰胺目标化合物63-72，另外，我们还对羟基转化为氨基的反应进行了探索。3。

In anthropology, ethnographic researchers spend years living immersed in the cultures they study and record.

在人类学中，人种学研究人员在其所研究和记录的文化中花数年的时间进行浸入式的生活。

By using the method of space substituting time, alpine-cold steppe in different ages of enclosing was studied. We selected 4 flat plots with relatively uniform topography and enclosed time were 1-year old exclosure (E1), 3-year old exclosure(E3), 5-year old exclosure (E5), unexclosure. The grasslands were freely grazing pasture, grazing rate of 5.7 sheep / hm2. After enclosure, it was used as spring pasture, 5.7-grazing sheep / hm2. Unexclosure plot were 5.7-grazing sheep / hm2 in addition to the winter.

本文，运用空间代替时间的方法对不同围封年限的草地进行研究，结果表明：（1）随着围封年限的延长，天山赖草种群在群落中的地位逐渐弱化，优良牧草羊茅和紫花针茅种群在群落中的优势逐渐体现出来，群落由天山赖草+黄花棘豆群落类型逐步向羊茅+紫花针茅群落类型过渡。

During the mid-Warring States, Chunyu Kun of Qi State successfullyapplied folk controversial and speaking art in court and dealed with satire and remonstration in the funny and humorous atmosphere, leaving the works similar to Mixed Fu for ansering questions.

战国中期，齐国的淳于髡长于论辩，善于调侃，在宫廷中成功地运用民间论辩讲诵伎艺，在滑稽诙谐的氛围中进行讽谏，留下了类似于对问体杂赋的作品。

A hydrophone was used with a Fast Fourier Transfer analyzer to monitor and investigate the frequency spectrum during the ultrasonic-vibration treatment. The cavitation behaviors and erosion mechanisms of treated liquids were based on the observation of bubble dynamics and high-speed digital photographs.

主要利用水听器配合快速傅立叶转换器(Fast Fourier Transfer； FFT)进行超音波在液体中的频谱监测与调查，透过空泡动态观察及高速数位照片的比较及分析，藉以了解超音波在各种液体中的空泡行为及作用机制。

The paper analyses two kinds of new formulas on the equivalent friction coefficient of V-belt drive in the present mechanical design and finds out that one is reasonable but has certain error and the other is wrong.

对现行机械设计中关于V带传动当量摩擦系数的2种计算公式进行分析。认为其中一种公式是合理的，但存在一定的误差；而另一种公式却是错误的。通过推导V带欧拉公式，给出了计算V带传动当量摩擦系数的准确公式，并在公式中引入了一个新的参数——摩擦力方向角。在考虑皮带拉力变化既有径向滑动又有周向滑动的前提下，改进后的计算公式比现有公式更加完善

The paper narrated the Lu Ling's novel's polyphonic factors from three aspects: the relation of the author and protagouist; the novel structure and the figure's relation structure; the protagonist's inner monologues. It pointed out the novel's generation reasons and essential features by describing the static phenomena, at the same time, it embodied the ego generation of the essay's art features by Dostoevsky, Fyodor's novel creation.

文章从作者与主人公在作品中的关系、小说结构与人物关系结构、主人公的内心独白三个方面入手分析路翎小说中的复调性因素；在对此进行静态的现象描述的基础上进一步指出其复调小说产生的原因和本质特征，同时以陀思妥耶夫斯基的小说创作作为参照，凸现出其文本艺术特征的自我生成性。
