Arbour said the current food crisis stems from several factors including distortions and in supply ing and demand and unfair trade policies.

Arbour 說，當(dāng)前的糧食危機是好幾個因素引起的欧美性恔图片在线观看，其中包括供需失衡和貿(mào)易政策不公。

The "reason" why governments tend to introduce distortions that discriminate against agriculture is that internal politics generally favor the urban population at the expense of rural people, despite the much greater size of the rural population.1 1 The political influence of urban consumers and industry enables them to exact cheap food at the expense of the vast number of poor rural people.

In this paper, a series of lunar map projection formulas are deduced including azimuthal projections, cylindrical projections and conical projections. The lunar map projections software is compiled. By caculating lunar map projection distortions, their projection distortion rules are found. Base on the lunar exploration mission, the lunar map projection scheme is given in this paper. The azimuthal conformal projection or the circumcenter perspective azimuthal projection is usually used in small areas, especially in two poles. When the whole map of the moon is needed, the azimuthal conformal projection or the circumcenter perspective azimuthal projection is used within 10° in the poles, and the traverse tangent cylindrical conformal projection or the normal secant conical conformal projection can be used in else areas, furthermore, band-division is necessary to reduce the projection distortion.

The original data used were 5 in 12 RFLPs of a mouse F2 population including333 individuals presented in the software MAPMAKER.Classical and successive x2 testswere used to check segregation distortions of the codominant markers. And the resultexhibited that successive x2 tests was more efficient.

The major findings include:(1) By using fuel as the base indicator of relative efficiency, we found the following input factors' distribution inefficiency for domestic airlines: The distribution inefficiency of labor and capital input factors differs from airline to airline, and is becoming more severe with time; the distribution inefficiency of other factors does not differ very much among airlines but varies with time. It is inefficient from 1989 to 1995 but becomes more efficient during 1996 to 1997;(2) Airline companies have higher economies of density before 1996, but tend to show a constant return to density in 1997 when considering allocative distortions. The technical efficiency of input factors as a whole has declined after the open-air policy;(3) The costs of airlines are increasing significantly due to their distribution inefficiencies;(4) The instrument variable generated through a quasi price function does not have significant influence on cost; this may imply that airline companies in this time period did not exhibit the phenomena of high-quality high-price.

In the second step,the parameters estimated in the first step are improved iteratively through a nonlinear optimization,based on the coplanarity condition,taking into account camera distortions.This works well if there are three sets of parallel lines independently in the view scene.
