Fifty female patients who were selected to schedule for mammary gland tumor excision surgery, were divided into 2 groups(n=25 in each group): group A: received propofol's half-effective concentration at 3.0 μg/ml in Marsh model by TCI; group B: received propofol's half-effective concentration at 4.0 μg/ml in Marsh model by TCI. All patients were given remifentanil in Minto model by TCI after being given propofol which reached the balance between effect-site concentration and blood plasma concentration. The target concentration of remifentanil was determined by a modification of Dixon's up-and-down method. Laryngeal mask insertion was attempted after 10 mins, the insertion condition and success rate were observed, then the suitable target concentration of remifentanil(ECe50) were calculated.

50例女性乳腺良性手术患者随机分为2组（n=25），A组：靶控输注丙泊酚效应室浓度3.0 μg/ml；B组：靶控输注丙泊酚效应室浓度4.0 μg/ml（均为Marsh药代模型），待其效应室浓度和血浆浓度达平衡后给予靶控输注效应室浓度瑞芬太尼，运用Dixon's序贯法确定喉罩置入时瑞芬太尼浓度，10分钟后置入喉罩并观察喉罩置入条件与成功率，计算出相应的瑞芬太尼适宜靶浓度（ECe50值）。

Given the expectation for the function of the government in an open economy, the fiscal policy should play an important role in stabilizing economic fluctuation. It is well recognized that, however, the fiscal policy is far away from achieving the stability of the economy. In contrast, the fiscal policy itself in many cases is the main source of instability, and the misplacement of the fiscal policy sometimes leads to larger risks.

但是，许多学者认为，在开放条件下，财政政策远远不是它本应成为的一国经济的稳定力量，在很多情况下，本身却成为对外部门不平衡的主要不稳定力量，尤其在发展中国家，财政政策对一国的经常项目和资本项目都有非常大的影响，财政政策的失误往往会造成更大的风险。
