According to this view, the so-called scient
25、ific method is the basis for scientific development. The scientific method is said to have three steps.The first step is that of careful observation- often involves looking for relationships among different kinds of events. If a specific relationship seems to be true in a number of cases, without an
26、y exceptions, then it may be hypothesized that the relationship holds in general.The second step of the scientific method may be the formulation of such a general hypothesis. Or it may be an attempt to explain phenomena by theorizing the existence of a deeper reality. Examples of the 3-latter are th
27、e atomic theory of matter and the wave theory of light. No one has over actually seen an atom with the eye nor seen light travel as a wave; that is why we call them theories or hypotheses rather than facts. The value of such theories is that they can be used to explain many unobservable phenomena. A
28、 good theory then, results in a more unified view of nature. When a theory brings together many phenomena under a single concept, the hypothesized relationship is called a natural law.The third step, the testing of the theory, may involve further experimental testing of hypothesized relationships. O

31、深刻的现实存在进行推理来解释各种现象。物质的原子理论和光的波动理论就属于后一种情况。从未有人亲眼看到过原子，也没有人看到光以波浪形式传播，这就是为什么我们把它们称作理论或假设，而不称作事实。这种理论的价值就在于，他们可以用来解释许多无法观测的现象。因此，一个好的理论能够使人们在对自然的认识方面达成更好的共识。如果某种理论能够通过一个概念把许多现象划归为一类，那么这个假设关系就成为自然定律。第三阶段，即检验真理阶段，可能需要对所假设的关系通过实验进一步加以检验，也可能通过实验来证明新理论所预言的新现象。爱因斯坦的相对论预言，质量可以转变为能量，能量也可以转变为质量（这就是著名的方程式E=mc2
32、的含义） 。以前从未想到够这一转变是可能的，但是在爱因斯坦提出这个预言几年后，这一点就被实验所证明了。7.Patents and InnovationPatents play a central role in empirical research on innovation, despite their limitations as measures of the introduction of new products, processes, and services. They identify the inventors, assignees (i.e., patent holders

The few studies that sought to understand the technological development of China and East Asian countries were constrained to the limited number of patents awarded by the U.S. Patent and Trademark Office (

These studies were hindered by (i) selection bias, as the sample of Chinese firms willing and able to file a patent with the USPTO is severely restricted compared with the entire population of Chinese firms, particularly start-ups; and (ii) underrepresentation of governme
