In consideration of cost efficiency and convenience, the dermis and subcutis could be examined simply by the 3D PPG graph derived from the proposed PPG array system. According to the amplitude of 3D PPG waveforms, the situation of skin could be evaluated that the worse skin processes the larger standard deviation of amplitude.

A ring of integers derived from the set of all integers according to the following rule: Let N be an integer greater than 1, and A and B be two other integers; if N is a factor of A?

由全体整数的集合按下列规则产生的整数环：设N为大于1的整数，A和B是两个其它整数，若N是A？

Based on the regional tectonic evolution, combined with the high precision isotopic ages from this paper and other geologists, we have some new acquaintances as follows: 1 There has no Caledonian granite belt distributed in north margin of North China Craton. So, the traditional evolving model of North China Carton, which formed on this idea and the acquaintance about the collision of North China plate and Siberian plate, must be incorrect; 2 The age date show that the earliest magmatic activity began since late-Palaeozoic Permian, which is inconsistent with the previous idea that there were Caledonian and Hercynian active continental margin in the north of North China Craton and in the south Xingkai Massif. 3 the crust and lithosphere were thickened by the subduction and collision of Siberia plate and North China plate during Late Paleozoic. The magma is formed when the crust is heated and melts caused by thickened lithosphere delamination and caused the Asthenosphere upwelling. But only a little basaltic magma erupted, most magma underplate under the bottom of the crust. Thermal energy derived from basaltic magma underplating made the middle and lower crust melt partially and the late Permian-early Triassic granites is formed in large scale.

根据区域构造演化分析，并结合本文及他人高精度同位素年龄，我们对延边花岗岩形成的大地构造环境有了新的认识：1在华北地台北缘并不存在所谓的加里东花岗岩带，因此，建立在此之上的传统的华北地台北缘演化模式及有关西伯利亚板块与华北板块的碰撞拼合的认识也必然是不正确的；2华北地台北缘和兴凯地块南缘不存在加里东期和海西期花岗岩带，表明两地块边缘最早的花岗质岩浆活动始于晚古生代的二叠纪，即不存在传统观点所认为的加里东期或海西期活动陆缘；3晚古生代由于西伯利亚板块与华北板块的俯冲碰撞，致使地壳和岩石圈增厚，导致加厚岩石圈发生拆沉作用，使得软流圈上涌，加热地壳使之熔融形成岩浆，但玄武质岩浆少量喷出地表，大部分底侵于地壳底部，形成下地壳高密度的玄武质底侵层，玄武质岩浆底侵的热能引起中下地壳广泛部分熔融，形成大面积分布的晚二叠世—早三叠世花岗岩。

The dressed carcass and all organs derived from the carcass shall be condemned if the skeletal muscle from that carcass gives a violative result.

如果畜体骨骼肌的检验结果不合格，分割后的畜体和来自畜体的所有器官都应该宣告为不适于食用。

The resplendence derived from expensive paint decides that its main function can only be decorative. In his works spanning from 2004 to 2007, Chen Qiang has sedutively redeployed this decorative character; which in his cubic work "Beautiful Time" inosculates with the toning of organic glass and technical inlaying and firing to such a fine degree, that the decorative limit has been reached.

昂贵颜料的珠光宝气注定其主要用途是装饰，陈墙二00四年到二00七年的作品怂恿般地调度这种颜料的装饰气质，在立体作品《美好时光》中，其与有机玻璃的涵衬和与镶嵌及烧制工艺的吻合，挖掘到它的装饰极限。

A student who is or was a resident of the other side immediately before visiting one side, and who is present in the first-mentioned side solely for the purpose of his education shall be exempted from paying taxes in that first-mentioned side on the payments derived from sources outside that side for the purpose of making a living, accepting education.

学生是、或者在紧接前往一方之前曾是另一方居民，仅由于接受教育的目的，停留在该一方，对其为了维持生活、接受教育的目的收到的来源于该一方以外的款项，该一方应免予征税。

Thus we conclude that JA might be one of the potent factors, other than auxin, involving in the regulation of LR formation.3. Relationship between JA and SA on LR formation in rice seedlingMouse monoclonal antibodies against salicylic acid was produced and characterized for the first time. The McAb S2-8F, were derived from an immunogen in which 5-aminosalicylic acid (5-ASA) was conjugated to KLH (hemocyanin from keyhole limpets) through its-NH2 group.

实验结果还表明IBA对水稻幼苗侧根发生的促进作用可能并非是通过转化为吲哚乙酸(indole-3-acetic acid，IAA)而实现，因为外源IAA不能促进水稻幼苗侧根的发生，荣莉酸对水稻幼苗侧根发生的诱导效应及其与生长素和水杨酸的关系却和 IBA一样可以抑制种于根伸长及促进侧根伸长，只是IAA具有这种效应需要的浓度是IBA的20多倍。3。

Maize inbreds belonging to 3 maize heterotic groups including Reid, Tangsipingtou and compound germplasm were studied to determine the influence of genotypes, media and plant regulators on the embryo-derived calius induction and green plant regeneration. Immature embryos (1.0~2.0 mm) from selfed ears were harvested as explants. Callus could be induced from all the tested inbreds. However, plant regeneration was only obtained in 12 genotypes.

以Reid、唐四平头和其它种质等3个杂种优势类群共19份玉米自交系为试验材料，以玉米幼胚作为外植体，研究了基因型、培养基和激素对玉米幼胚愈伤组织的诱导及植株再生的影响，结果表明供试材料均能进行愈伤组织的诱导，但是仅有12个自交系能再生植株。N6和改良N6培养基有助于提高愈伤组织的质量及其生长速度。2，4-D在愈伤组织的诱导中起着关键性作用。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
