Non-Inertial Reference Frame Gravitational attraction The Law of Universal Attraction was already introduced in lecture D1. The law postulates that the force of attraction between any two particles, of masses M and m, respectively, has a magnitude, F, given by F= (1) where r is the distance between the two particles, and G is the universal constant of gravitation. The value of G is empirically determined to be

从内蒙古某处土壤中分离出一株分解尿素的产氨细菌（命名为 JAT-1），革兰氏阴性，菌落表面平整湿润，乳白色，短杆状.菌体尺寸为φ0.2~0.4μm×1.5~2.0μm.结合16S rDNA测定和菌株系统发育树分析，其与Providencia Sp. Sam 130-9A同源性高达99%.对其生长特性研究结果表明：JAT-1以10 g×L-1柠檬酸钠作为碳源，20 g×L-1尿素作为氮源，最佳生长pH值范围为8.0——9.5，最佳初始接种浓度20%.采用该细菌进行碱性铜矿摇瓶浸出实验，144 h后铜浸出率可达42.38%，表明该菌株具有应用于碱性铜矿浸出的潜力

一、解释：（20%） 1、单位转速 H nD n 1 11 = 表示当 D1=1m,H=1m 时水轮机具有的转速。 2、飞逸转速 当水轮机发电机组突然丢弃全部负荷时，如调速机构失灵或其它原因使导水机构 不能关闭，机组转速将迅速升高并达到某一最大值，该转速称作飞逸转速

2.2 Estimating Overall Forces -Vertical dead loads(5～10kN/m²) -Vertical live loads = equivalent dead loads(2～5kN/m²) - Horizontal wind load - Horizontal earthquake load 2.3 Aspect Ratios and Overturn Resistance Aspect ratio (h/d) is one of the main considerations in schematic level. It is very important for overall stability of a building against overturning. 2.4 Strength and Stiffness of Buildings Carrying capacity –enough strength (against loads) Rigidity of building – enough stiffness (against deformation) 2.5 Symmetry and Asymmetry in Building Forms Asymmetry building is caused by: - asymmetry of building elevation - asymmetry of supporting system - asymmetry of dead loads or live loads

Our task How to estimate and test discount factor model. Ep,=E(m (data 1, parameter)) 1. Bring an asset pricing model to data to estimate free parameters. For example, parameter,yinm=B(c+1/c)-y Or the b in m=b f 2. Evaluate the model, is it a good model or not? Is another model better?
