     The risk measure method of Conditional Value-at-Risk is developed on basis of the shortcoming of Value-at-Risk method, which is raised by Rockafellar at 1999. The implication of CVaR is the conditional loss over VaR of portfolio, which reflects the average exceed quota.
     CVaR(Conditional Value-at-Risk,条件风险价值、)风险测量方法是在VaR(Value-at-Risk,风险价值)风险测量方法的缺陷基础之上所产生的,最早是在1999年底由Rockafellar提出的,其含义是:组合损失超过VaR的条件均值,反映超额损失的平均水平。

短句来源
     The risk measure method of CVaR(Conditional Value-at-Risk)has been developed on basis of VaR method, the implication of which is the mean of loss's β-tail distribution(0 < β< 1 is the confidence level). The method of CVaR is a coherent measure of risk, can reflect the potential risk of investment portfolio and is more easily to compute.
     CVaR(Conditional Value-at-Risk,条件风险价值)风险度量方法是在VaR风险度量方法的基础之上产生的,其含义为:资产组合损失的β尾部分布的均值,其中0<β<1为给定的置信水平。

Singular Value Estimates for Certain Convolution-Product Operators
      
We present two-sided singular value estimates for a class of convolution-product operators related to time-frequency localization.
      
Singular Value Estimates for Certain Convolution-Product Operators
      
The sampling theorem is a Kramer-type sampling theorem, but unlike Kramer's theorem the sampling points are not necessarily eigenvalues of some boundary value problems.
      
We study boundary value problems for the time-harmonic form of the Maxwell equations, as well as for other related systems of equations, on arbitrary Lipschitz domains in the three-dimensional Euclidean space.

Both sectorphotometer and microphotometer analyses were carried out on the Hg spectrum transmitted by papers popularly used as window materials in Chinese homes. The intensity distribution of transmitted radiation, after normal incidence, through samples of nine different kinds of paper have been studied, and the total transmission calculated for various wavelengths.

以水银灯为光源,正射於纸上,其透射部份,用分光摄影法定量。以分圆光度计(Sectorphotometer)及显微光度计(microphotometer)量出九种窗户纸之紫外线透射性。并实验各种纸之抗断强度及其纤维之构造等,俾得相当之评价。 通常窗户纸对於具有最高生理效用之紫外线(波长2967A.U.)之透射量可居百分之十九至四十一;我国南部之壳片窗亦可透射百分之二十。至於玻璃窗,其透射量则等於零。外国虽有特备之玻璃能透射百分之二十至八十之此种紫外线,但其价值殊昂,不能使其遍普应用,可见两者反不若我国之窗户纸为佳矣。 窗户纸中以平粉连纸透紫外线最多,如将纸上桐油,则可视线及紫外线之透射力,皆有可观之增加,同时亦可去潮湿以致易破之影响。倘以普通之豆油油之,则其易於变黄,并减低其紫外线透射力,甚不适宜也。 如欲得较完全之讨论,请参考陈尚义之硕士论文,现存於燕京大学图书馆。

This is a continuation of a previous study (Li, L. Y, et al. 1951, Fukien Agr. Jour., 12(3, 4): 107-112) on the outdoor culture of straw mushroom in Fukien. The present work includes: (1) investi- gations on the analysis of fresh Fukien grown straw mushroom, (2) isolation and culture of Volvaria esculenta and our trials in using pure-culture spawns to grow mushroom, and (3) preliminary obser- vations made on the environmental requirements of Volvaria esculcnta The results are briefly summarized as follows: ...

This is a continuation of a previous study (Li, L. Y, et al. 1951, Fukien Agr. Jour., 12(3, 4): 107-112) on the outdoor culture of straw mushroom in Fukien. The present work includes: (1) investi- gations on the analysis of fresh Fukien grown straw mushroom, (2) isolation and culture of Volvaria esculenta and our trials in using pure-culture spawns to grow mushroom, and (3) preliminary obser- vations made on the environmental requirements of Volvaria esculcnta The results are briefly summarized as follows: 1. Our analytical work shows that the straw mushroom con- tains 92. 39% water, 206. 275mg. of ascorbic acid in 100g. of fresh mushroom, 2. 6024% sugar, 2. 6603% protein, 2. 2406% oil, and 0. 9118% ash. 2. Pure cultures of Volvaria esculenta could be readily obtained by innoculation with spores from fresh unopened mushroom. Cultures grow well on potato, corn, rice and rice-kernel husk media. 3. By employing pure-culture spawns, it takes only ten days for the first appearance of mushroom after spawnning while it takes three weeks usually if mixed cultures are used instead. The total period of mushroom production is likewise prolonged by the use of pure-culture spawns. 4. Preliminary observations indicate an atmospheric tempera- ture of 70°to 80°F., and a humidity of above 80% are favorable for the growth of straw mushroom. Production of mushroom stops when the atmospheric temperature falls below 70°F. The period of outdoor culture in Fcochow is from the latter part of April till the end of October.

本文旨在介绍草菰的营养价值,纯种培植的方法,及草菰生长状况。经分析结果,草菰的营养价值较一般蔬菜为高,尤以丙种维生素更为丰富。用纯种培植草菰较普通方法培植的不仅可以提早一半时间出菰,且产菰日期延长,菰之产量亦提高一倍。草菰生长速度从菰纽露面至菰伞平张需经过四十八小时,采为食用,以在菰疱破裂后十小时左右采收为佳。

Many oxides of heavy metals when existing not in exact stoichiometric combining ratios exhibit the properties of a semi-conductor.The resistance ofsuch materials has a very large negative temperature coeffcient.Such thermallysensitive resistors,known as“thermisters”,have found wide range of appli-cations in thermometry,communication engineering,etc.In this investigationwe tried over hundred samples of metallic oxides and their mixtures fusedwith glass powder to form small compact bead on Pt lead wires.The sampleswere treated by a new firing technique which is very convenient in laboratory.Some samples made from mixed oxides of Mn,Co and Ni showing a resistanceof 10~4-10~5 ohms at room temperature and 10-100 ohms at 500℃ seem.verypromising for practical purposes.

多种重金属的氧化物,经高温煅烧后,均可呈现电子性半导体的性质,其电导随温度急剧变化,故可作测量温度之用,通常称热感电阻。从电导的对数与温度的倒数的图中,可以推算半导体电导性所需的电子能位差。本文试验氧化物混入玻璃粉制成的小珠,用半导体体内电热法制成热感电阻,在常温时的电阻值为10~4—10~5欧姆,在500℃时只有10—100欧姆。半导体与铂导体线间的电性接触,经实验推知是良好的。这种制备方法,在实验室里,非常简易。经多次试验,以混合锰、钴、镍的氧化物和玻璃粉制成的电导性较大,有实用价值
