  lifting
Lifting smooth curves over invariants for representations of compact Lie groups
      
We show how any discrete wavelet transform or two band subband filtering with finite filters can be decomposed into a finite sequence of simple filtering steps, which we call lifting steps but that are also known as ladder structures.
      
Wavelet design for extracting weak fault feature based on lifting scheme
      
A new wavelet method based on lifting scheme to match weak fault characteristics is proposed.
      
In this method, an initial set of finite biorthogonal filters is modified by a lifting and dual lifting procedure alternately, and different lifting operators and dual lifting operators are obtained.

In recent years, the geotectonic problem of China engages the attentionof many Chinese and Soviet geologists, but different opinions are confessed by different authors. After studying the structural characters of the fundamentalfloor and its later geological development, theauthor of this paper agrees withthe statement of the Soviet geologist, B. M. Синицын. In 1952 he pointed outthat the Chinese platform in eastern China, may bs divided into: (1) theSine-Korean platform; and (2) the Southern-Chinese platform, consolidatedas a result of the Luliang movement. This Chinese platform especially in its southern part shows a very peculiarphenomenon as it is called "Activization" of the platform. During Sinian andPaleozoic, its sediments belonged to the pronounced epi-continental type, duringthe mesozoic the south-eastern part of the Southern-Chinese platform wasneither a stable shelf nor a geosyncline, but an intermediate type between them.Its characters were really not geosynclinal, but sometimes showed geosynclinalaffinities, as for instances, the immense granitic intrusions, the eruptions oflavas, and the rather strongly folded geosynclinal structures. These imply thelimited mobility or the incomplete consolidation of the underground. Accor-dingly, referred to the structural type of this region, P. Misch called it"Sinotype". Furthermore, in the Southern-Chinese platform, two strong "Activizingunits" are recognized as follows: 1) The Hunan-Kwangsi activizing andsubsiding region; 2) The Cathaysian activizing oldland. The "Activization"of these regions lasted for a long geological time. It began in Sinian, throughCaledonian, Variscian, Indo-Sinian, Yenshanian and even Himalayan. BeforeMesozoic, the Caledonian was the most intensive and widely distributed one.But as pointed out by A. H. Мазарович, the Caledonian of the Southern-Chineseplatform was merely a fold-belt within the platform. According to its geotectonic history, its character of sedimentation, itsregional metamorphism, its igneous activity and its geotectonic systems, suchas "Kwangsi ∈ system", "North-Kwangtung ∈ system", "Meso and Neo-Cathaysiansystem", and the "Nanling eastwest tectonic zone", it is the author's opinionthat the "Imtermediate type (Sinotype)" of the Southern-Chinese platform wasdeveloped gradually through a long "Activizing process". This "Sinotype" is anintermediate type between the stable shelf and the geosynclinal region.

作者同意B.M.西尼村的意见,认为中国地台是中国东部的一个大的构造单位,它是在吕梁运动后造成的。中国地台由两个主要部分构成,它的北部称中朝地台,南部称华南地台。中国地台有一很重要的特征,就是一个“活化”的地台。华南地台的东南部“活化”尤其强烈而显著,在中生代的太平洋运动时,差不多具有类似地槽的特征。但是它的“活化”是有悠久历史的,即开始於震旦纪,所以加里东运动给与很大的影响,但加里东运动只是地台内部的褶皱。地台“活化”直到中生代太平洋运动才得到高度发展,产生巨大的火成活动以及“中国式”的构造型式。新生代时地台还有中等强度的运动和火成活动。自第四纪冰期之后,地台仍在较弱的升降运动中。华南地台无论从沉积岩相、区域变质及火成活动,或从山字型、华夏式及南岭东西褶皱的构造体系等构造型式发育史的研究,都可以看到它的“活化”过程,在这过程里发育了“过渡类型”的构造形态,这都是不同放地槽或地台的构造形态的。本文是作为学习心得性质的初步尝试,文中不成熟和谬误之处尚多,希望得到大家的指正。如果能在集体的讨论和研究之下将我国大地构造研究清楚的话,这是作者所衷心期望的。

We have made three pyrex floats of the bulb-rod stream-line type, modified from that used in the Trail laboratories. These floats possess cach a thick-walled bulb 6.5 mm in diameter, with an upper rod 3.5 mm long and a lower rod 8 mm long, each rod being 2.5 mm in diameter and forming an angle of 60° at the end.

We have made three pyrex floats of the bulb-rod stream-line type, modified from that used in the Trail laboratories. These floats possess cach a thick-walled bulb 6.5 mm in diameter, with an upper rod 3.5 mm long and a lower rod 8 mm long, each rod being 2.5 mm in diameter and forming an angle of 60° at the end. With baths having temperature fluctuations within ±0.0005°, the velocity-temperature relationship has been determiued in the neighborhood of their flotation temperatures. It is found that the temperature iuterval in which such a relationship is linear is much more extensive when the flotation temperature of the float is lower. Correspondingly, the velocity interval is only slightly larger. The results are as follows:Float Flotation Temperature Velocity intervalNo. temperature, ℃ interval, ℃ mm/sec1 28.86 ±0.08 ±0.192 24.17 ±0.12 ±0.203 17.79 ±0.26 ±0.22So it is advcntageous to use floats with lower flotation temperatures. With Aoat No. 2 we have determined the deuterium contents of two samples of heavy water.Besides, we have measured the effect of pressure on the flotation temperatures of these floats. Float No. 1 has been studied in more detail with the result that the relationship between the flotation temperature and the pressure is linear in the investigated pressure range of 48 cm Hg in the neighborhood of one atmosphere.

我們对於三只“球柱流線型”Pyrex玻璃浮沉子测定了升降速度与温度间的关系, 求得在室温左右,當浮定温度愈低時,並直線性關係的温度範圍愈大,相應的速度範圍也略大。在28.86°時,直線性關係的温度範圍為±0.08°,直線性關係的速度範圍為±0.19毫米/秒。在17.79°時,相應的數據是±0.26°和±0.22毫米/秒。因此,用浮定温度较低的浮沉子,可在約半度的温度範圍內選测两点,來求得重水的濃度。其次,我們在1大氣壓附近,測定了一只厚壁浮沉子在48厘米汞柱的壓力變動範圍内,浮定温度与压力变动呈直線性關係。
