To keep away from digital distortion caused by analog conversion,"Boutique Recording" applies APOGEE Analog to Digital Converter System in pre-recording, adopts Hi-End Prism Sound Digital to Analog Converter System during post mix and master disposal processes. In a word,"Boutique Recording" minimizes the distortion rate, and maintains the unique spirit of analog music.

为避免后期缩混时过多数字设备所造成的数码味，录音师坚持在前期录音与母带处理过程中使用传奇的模拟设备，在现场录音的同时进行立体声混音工作，为了避免模数转换时所造成的数字失真，达人艺典在前期录音中采用APOGEE模数转换系统，后期缩混及母带制作采用顶级HI-END厂牌Prism Sound数模转换系统，将失真率减到最低，保持独有的模拟音乐味道。

Results showed that the PMC meiosis of autotetraploid was similar to the diploid except some particularities. In metaphase Ⅰ, multivalent, quadrivalent, trivalent, bivalent and univalent were observed and some of the chromosomes were found not to rank on the metaphase plate and so did in metaphase Ⅱ cells. In anaphase Ⅰ and anaphase Ⅱ cells, there were lagging chromosomes, chromosome bridge and fragment. During anaphase Ⅱ and telophase Ⅱ, chromosome segregation was not synchronous or equal. At tetrad stage, dyad, triad, tetrad with micronucleus and polyad appeared.

结果表明，同源四倍体花粉母细胞减数分裂过程与二倍体相比，中期Ⅰ染色体构型复杂，有多价体、四价体、三价体、二价体和单价体；中期Ⅰ及中期Ⅱ有部分染色体没有排列在赤道板上；后期Ⅰ及后期Ⅱ出现落后染色体、染色体桥及断片；后期Ⅱ和末期Ⅱ有染色体不同步分离及不等分裂的现象；四分体时期还出现二分体、三分体、含微核的异常四分体及多分体。

Having failed in imperial examinations in 13 years, he achieved an ultimate knowledge that happiness comes after long suffering; His aesthetic personality underwent 2 stages at Yi-Yun-Ge—he pursued "spring" in earlier stage, and "autumn" in later stage, and in later period of his life at Yi-Yun-Ge, he pursued the Legalism with no impairment; Also demarcarated by his life at Yi-Yun-Ge, he self-assumed with arrogance in earlier stage and self-respected with Taoism in later stage in terms of his moral personality.

本文的人格研究着重探讨了其思想与人格形成的背景、审美人格、道德人格：倪元璐自幼受到父亲的儒家圣贤思想的教育，在亲身经历的十三年的举业挫折中深刻体会到苦尽甘来的人生道理及无穷的艺术境界；审美人格以衣云阁生活为分界线，前期追求春天，后期追求秋天，而且园客生活后期追求无害之"法"；道德人格以衣云阁生活为分界线，前期自任以狂，后期以道自重。

Li Yu's late word is that he's fine words, the use of live images of his late term for the distinctive feature, try this bleak picture from the construction and acquisition, desolate mood with the statement that the silent, desolate picture of the role and significance of the three aspects of the analysis, he adopted a bleak picture to express his statement said with silence, It was this bleak picture also makes use of the term late for his fine efforts out to the world love, making him a great word generation, Comments were as "progressing."

内容摘要：李煜的后期词是他词中的精品，凄凉意象的使用是他后期词作的明显特征，本文试着从凄凉意境的营造与构置、凄凉意境的言说与沉默、凄凉意境的意义与作用三个方面分析之，他通过营造凄凉的意境来表达自己的言说与沉默，也正是这种凄凉意境的使用才使得他的后期词作精品叠出，为世人所爱，使得他成为一代伟大的词人，被人誉为宋词的"开山祖师"。

The results showed that the higher thedischarge voltage or charge capacitor was, the higher the temperature of the plasma was,and the longer plasma discharge time was. There was a late discharge when the inputenergy reached the critical value. The greater the capacitance or voltage was, the earlier thelate discharge of the plasma was. The temperature changes of plasma at the beginning of alate discharge were not significant under different discharge conditions. Each SCB had itstemperature range respectively.

结果表明：放电电压或充电电容越大，等离子体温度越高，等离子体的放电时间也越长；对于不同的SCB，当输入能量超过一定的临界值后，将产生等离子体后期放电；电压或电容越大，后期放电开始的时间越早，而后期放电开始时的等离子体温度，在不同的放电条件下变化并不大，不同的SCB均有其各自的温度变化范围。

It expanded to 106119ha in 1973, descented to 99167ha in 1987, backed up to 112440ha, and attained the max value in history—123170ha in 1998 and descent to 109934ha again in 2001. GIS overlaying analysis shows that, the spatial change of Minqin Oasis had the different characteristics in different stage in the last 50 years: at the end of 50's to the beginning of 70%, oasis expandation Was performed by extension of origin oasis; the atrophia of oasis from the beginning from 70's to the 80's was performed by increasing of non-oasis spot pieces of inner part for oasis; the main performance of keeping on expanding of oasis from late 80's to late 90's is outside extension of Baqu oasis near the upper stream, with increased oasis area in interior of hungriness and increased area of non-cultivation in Huqu oasis in the north. From 1998 to 2001, opening up wideness in interior of hungriness continued, but hnngrinessization of oasis became worse. The oases in the Minqin Basin developed from small to large and back to small in terms of area changes, and from south to north then to south in terms of spatial changes.

绿洲分布图的GIS叠加覆盖分析表明，近50年来民勤绿洲的空间变化在不同阶段有不同的特征：50年代末至70年代初，绿洲扩展主要表现为已有绿洲的外延式扩大；70年代初至80年代后期的绿洲萎缩，主要表现为绿洲内部非绿洲斑块增加；80年代后期至90年代后期的持续扩展，主要表现为靠近上游的坝区绿洲向外围扩展和荒漠腹地绿洲面积的增加，而北部湖区绿洲弃耕面积不断扩大；98年至2001年，绿洲荒漠腹地的开荒还在继续，但湖区的绿洲荒漠化还在进一步加剧。50年来民勤绿洲的发展总体上经历了一个面积由小到大再到小，空间位置上从南而北再向南的迁移过程。

This thesis holds that all of Chao Yu's dramas should be divided into former period and latter period; the deep structure of former Chao Yu's dramas is the contrast and opposition of an ideal world to a prisonlike world, and the deep structure of latter Chao Yu's dramas is the"clear sky"; the transformation of former Chao Yu's drama to the latter is a transformation of its deep structure.

本文认为曹禺戏剧存在着前期和后期之分；前期曹禺戏剧的深层结构是闭锁的世界与理想国的对照与对立，后期曹禺戏剧的深层结构则是&明朗的天&；从前期戏剧到后期戏剧的转换是深层结构的转换。

The results showed: decapitation and suckering agents treatment can significantly increase leaves and leaf area index at topping later stage,enhanced chlorophyll content,extended the function of leaves,improved photosynthetic potential at the topping mid and later stage,and promoted a...

结果表明，打顶+抑芽敏处理可明显增加打顶后期单株叶数和叶面积指数，提高叶绿素含量，延长叶片功能期，增强打顶中后期光合势，促进后期净同化率和群体生长率增长，使打顶中后期光合特性维持在较高水平；打顶+人工抹芽和打顶处理也在一定程度上改善了生育后期光合特性，而抑芽敏处理对光合特性影响不明显。

The forming of kyanite sequence was probably related to an arc-continent collision event during the late Paleozoic, and the andalusite sequence may result from uplifting of the medium-pressure rocks and extensive intrusions of the collision-related granites.

早期中压型变质序列保留可能是离后期热源较远，从而出现完整的中压型变质序列；由于后期低压型变质速度快，从而保留了早期中压型的特点，同时又有后期红柱石型的特点，呈现出低压型与中压型变质混合存在的现象，或表现出向低压型变质转变的趋势。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
