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。

The results show that biomass owns higher NO removal efficiency than pulverized coal. NO removal efficiency of three kinds of fuels increases by different extent through the increase of reburn fuel fraction and the decrease of the excess air ratio. NO removal efficiency of corn straw is the most efficient; rice husk is medium, pulverized bituminous coal is the lowest. Within the certain reburn resident time (650 ms), NO removal efficiency increases quickly with the resident time.

研究表明：生物质脱硝能力明显高于煤粉，提高再然比例及减小过量空气系数，3种燃料的脱硝率有不同程度的提高，其中秸秆脱硝率最高，稻壳中等，煤粉最低；在一定的再燃停留时间内(650 ms)，延长停留时间，脱硝率增加，超过这一停留时间，脱硝率增加缓慢。

They elected representatives with no term of office and no perks, who were paid only an average worker's wage and were recallable at any time.

他们选举出了既没有人企业没有额外津贴的代表，只给这些代表支付一个中等熟练工人的工资，而且随时可以撤换。

The leaf angle and leaf reclinate value were all belong to quantitative trait, and heritability ratio were in the middle.

The initial stress field of surrounding rocks of shaft is regressively analyzed by 3D finite element method according to in-situ measured data by hydro-fracturing and distribution properties of in-situ stress.

根据竖井围岩地应力场和Kirsch解得到的围岩二次应力场，结合Russenes和陶振宇岩爆判据，进行了竖井岩爆综合预测和分析，得出竖井有轻微和中等岩爆发生的结论，并提出岩爆防治措施。

Acetate groups charge ZnO nanocrystals negatively and passivate the surfaces,reducing the surface defects and visible emission centers. Resultantly, the increase of acetategroups lead to the quench of visible emission and improvement of photoluminescenceproperties. At appropriate concentrations, the hydroxide groups mainly passivate the surfaceand improve the photoluminescence properties.

研究发现，氢氧化锂/醋酸锌的比值对胶体氧化锌量子点的发光性质有重要影响；醋酸根基团通过使氧化锌粒子带负电荷并钝化其表面，使得氧化锌纳米点的表面缺陷和可见发射中心大大减少，因此醋酸根浓度的增大导致了可见发光的淬灭和发光性质的增强；氢氧根基团在中等浓度时主要起钝化氧化锌表面的作用，使产物的发光性质得到改善。

And if the director is a lower monitor, the direct may retent higher ability CEO than the high monitor director.

监督低的董事对于股东是有利的，因为过高的监督的董事倾向于雇佣中等能力的经理层。

Normal term newborns were examined as control. In 34 cases, there were no retrohepatic hyperechogenicity and the X-ray showed normal. In other 6 cases the sonographic pattern was discrete linear echoes, and X-ray showed wet lung.

而40例正常新生儿，有34例在肝脾后未见任何回声， X线胸片提示心肺正常； 6例显示在肝脾后可见稀疏的中等回声， X线胸片提示湿肺。

Results The supratentorial lesions involved the occipital lobe in 4, frontal lobe in 3, fronto-occipital lobe in 2, temporo-occipital lobe in 3, lateral ventricle in 1 case and the saddle region in 1. All the lesions were large in volume and most of them presented heterogeneous signals in MRI. Of the 14 cases, 12 showed cystic degeneration and necrosis, 2 had hemorrhage and 6 showed signs of emptied small blood vessels. Twelve cases had heterogeneous enhancement and 2 had moderate enhancement. Pathologically, 10 cases of neuroblastomas were identified, along with 3 ganglioneuroblastomas and 1 atypical rhabdoid tumor.

结果 病灶位于顶叶4例，额叶3例，枕顶叶2例，颞枕叶3例，侧脑室1例，鞍区1例，病灶普遍较大，病灶绝大多数信号不均匀，病灶内可见囊变／坏死（12例）、出血（2例）、流空小血管影（6例），增强后病灶呈明显不均匀强化（12例），中等强化2例；神经母细胞瘤10例，节细胞神经母细胞瘤3例，非典型横纹肌样瘤1例。
