总结示例：
在本实验中，我们利用手机软件Phyphox的声学秒表功能来测量小重物自由落体的时间。测量时通过多次重复测量的方法来减小偶然误差，利用作图的方法求出高度与时间平方的比值大小，最终计算得到**地区（例如：福州地区）的重力加速度大小。实验测量值与当地的重力加速度的理论值还是比较接近的。

I now realize that the major strength of air cargo — its ability to respond to sudden changes in consumer demand — is also its major weakness. I’m developing the view that any prediction in air cargo is pointless if it’s based only on a recent or short-lived trend (like the one displayed in 20XX), rather than the extrapolation of a long-term picture that has been proven right by history. You could say that this risks missing the next major opportunity, but I don’t think so. It avoids the equally serious risk of assuming lots of additional overhead that could quickly become a millstone if predictions fall short. History usually repeats itself, and long-term trends of the past, which incorporate past peaks and troughs, are a much better basis for predicting future trends. That alone is not enough, however. The trick is surely also to factor in additional growth from real prospects of business gains that are within your influence and consider the possible effects of any real

Metro AG Introduction Metro AG, often referred to as the "Metro supermarket", is largest retail in Germany, the second largest retail in Europe, and the third largest in the world's retail wholesale supermarket group1. In the Metro and WanKeLong (only European) brand with a number of Metro market. The company is the composition of German DAX stock index, is one of the world's top 500, has branches in 32 countries. It is created by Otto Beisheim, headquartered in Dusseldorf now. In 1964, in the field of business, a new idea and management mode was born in Germany, this is the Metro. Manage Cash and Carry in 32 countries around the world now,and provide for the delivery system shopping malls, large department stores, super discount supermarket chain stores, specialty stores, etc. Enterprise mission: metro is a kind of Cash and Carry shopping mall,service for professional customers and commercial customer. Metro provides high-quality goods and business plan for professional customers at the lowest possible price. 1 background Metro group structure is clear. The metro group runs from the strategic management of the whole corporation. Metro group is divided into four parts, the operation of the company has six independent sales area and different brand. Cash and Carry service for business and professional customers, other part is for retail sales and the final customer2. So-called service across the region refers to provide services for all sales areas within the company of the group, such as procurement, logistics, information technology, advertising, finance, insurance, food and beverage. Metro now buy is metro group’s most sales ability and the internationalization of branches. Today, the group has set up a file in the 33 countries around the world with more than 2100 stores. Under the joint efforts of the 100000 employees, the company turnover up to35 billion euros in 2011. 2 current retailing strategy 2.1 target market Target customers of most of the common market is no difference, namely the service object is the ordinary consumers, repeat purchase rate of consumers is high in the short term , but every time quantity of purchase is not big, consumer behavior is temporary and more randomness . And target consumers of warehouse supermarkets are more clear. Metro service for "limited" customers, refer to the operators in the field of industry and commerce, implement membership for group consumers3. And status of the members must be legal enterprises and institutions. 2.2 market positioning 1 Fansi. Supply chain management research on Metro (China)’s own brand of goods [D].

大学物理实验报告 Ferroelectric Control of Spin Polarization Controlling the spin degree of freedom by purely electrical means is currently an important challenge in spintronics (1, 2). Approaches based on spin-transfer torque (3) have proven very successful in controlling the direction of magnetization in a ferromagnetic layer, but they require the injection of high current densities. An ideal solution would rely on the application of an electric field across an insulator, as in existing nanoelectronics. Early experiments have demonstrated the volatile modulation of spin-based properties with a gate voltage applied through a dielectric. Notable examples include the gate control of the spin-orbit interaction in III-V quantum wells (4), the Curie temperature T C(5), or the magnetic anisotropy (6) in magnetic semiconductors with carrier-mediated exchange interactions; for example, (Ga,Mn)As or (In,Mn)As. Electric field–induced modifications of magnetic anisotropy at room temperature have also been reported recently in ultrathin Fe-based layers (7, 8). A nonvolatile extension of this approach involves replacing the gate dielectric by a ferroelectric and taking advantage of the hysteretic response of its order parameter (polarization) with an electric field. When combined with (Ga,Mn)As channels, for instance, a remanent control of T C over a few kelvin was achieved through
