介入

After World War II, with the enforcement of a series of education laws such as the National Defense Law, the Higher Education Act of 1965, the 1972 Reauthorization of Higher Education Act, the Middle-Income Student Assistance Act , the Student Loan Reform Act of 1993, the U.S federal government has gradually set up a complete financial aid system. The system is based on student loans as its main aid form and supplemented by other forms of aid such as grants, scholarships, federal work-study programs and federal tax credits.

二十世纪三四十年代后，尤其是二战后，联邦政府出于国家利益的考虑，开始关注高等教育，从而介入学生资助领域，先后推出《国防教育法》、《高等教育法》及其系列修正案、《中等收入家庭学生资助法》、《学生贷款改革法》以及《纳税人救助法案》等一系列高等教育资助法案，逐步建立起以学生贷款为主体、辅之以助学金、奖学金、联邦工读计划以及联邦税收补贴等形式的完善的联邦政府学生资助体系。

Much as Gao's analysis is used to critique the problems arising from the West's selection of contemporary Chinese art, the application of this realist reflectionist approach on contemporary art is also remarkably popular among critics in China today.

高名潞的这段论述虽然是用来批评西方在选择中国艺术时出现的问题，但用这种现实主义反映论来论证当代艺术的方法在中国当下的评论界也随处可见，他们把前卫艺术的介入社会，理解成反映社会，然后把反映社会现实的作品当作当代艺术，所谓的现在是数码时代，艺术要反映数码，现在是卡通时代，艺术要反映卡通，还有就是高名潞所批评的，只要在艺术中反映了一点中国的变化就是当代艺术，而其实它只是现实主义反映论的一种表现，鲁虹等人的文章都属于这一类，我称为&改革开放现实主义艺术&模式，我们看到今天的中国艺术和评论都是在这种模式中制造当代艺术的假象。

Due to Jin's use of negative shots, this series of photographs does not correspond to the realist reflectionist theory right from the very beginning. It does not reflect or present any social phenomenon. Instead, it transforms the phenomenon into a problem situation that offers and invites review. In contemporary art, to intervene society by way of negation is strategic, as can be seen in Jin's Great Economic Retreat: the images featuring empty factory buildings reveal more than that. When the enlarged photos are exhibited in a museum gallery, Jin's real question surfaces: is what post-colonial economy brought China a blessing or a curse?

金江波的这组《经济大撤退》图片由于用了否定性的镜头而使得它一开始拍摄的时候就不是现实反映论的，它不是去反映和呈现了社会的什么现象，而是将这种社会现象转换为一种问题情境，提供给人们反思，而在当代艺术中，否定性地介入社会是它的核心，就像金江波的《经济大撤退》，图片虽然呈现了空厂房，但不只是呈现了空厂房，当这些图片通过放大展示在美术馆中，那些后殖民经济对中国来说到底是喜还是忧才是金江波想要问的？

Methods Dose measurement system(Diamentor K1)equipped with DSA machine(Angiostar-Plus,Seimens,Gemany),analyzed dose-aera-production(cGycm2)and entering doseof 432 patient having received interventional vascular radiology for diagnosis and treatment regressively.
