The effectiveness of market theory tells us that stock prices fluctuate in line with the random walk model, only the price history of the historical information contained herein, which is the basis for the creation of the technical analysis of the premise - is a repeat of history, the history of the price includes all the information is a huge challenge , And most of the technical analysis of empirical studies have shown that even if technical analysis can be brought about by excess profits, excess profits that are often not considered in the transaction costs of the case emerged, whether technical analysis can provide investors with continued access to Excess profits have doubts about that.

市场有效性理论告诉我们，股票价格波动符合随机漫步模型，历史价格只包含历史信息，这对技术分析赖以成立的前提——历史是不断重复的，历史价格包含所有信息是一种巨大的挑战，而大多数对技术分析实证研究也表明，即使技术分析能够带来超额利润，这种超额利润也通常是在不考虑交易成本的情况下出现的，技术分析能否可以让投资者持续地获取超额利润是有疑问的。

In the thesis by teaching the four-year students of 93 and grade 94 of P E department the techniques of volleyball smashing,anopting the different take-off and by comparing the diffenent results in doing it between the two groups of the formet learners and the later ones the author think that in teaching the beginners two-foot take-offshould ocme first And after that the strdents should be taught with techniques of one-foot take-off.

本文在对排球普修课扣球技术采用不同起跳方法的教学基础上，对实验组、对照组助跑摸高成绩进行了比较分析，认为在对初学者扣球起跳技术的教学中，应以并步起跳为宜。掌握了并步起跳技术以后，再向学生介绍跨步起跳技术。

The follwing three aspects are considered. First, gene has been regarded as the research objective and a history of genetics is the history of further understanding of the substantiality of the gene. Second, based on the highly developed molecular genetics, the genetics of scientific morphology is changed into the biological technology of technological morphology. And third, the development of the biological technology sufficiently shows the dual character of the new technology as a two-bladed sword, and it...

讲述3个方面：第一，遗传学研究者自始至终把基因作为研究对象，一部遗传学史，就是人们对基因实体性认识不断深化的历史；第二，在分子遗传学高度发展基础上，科学形态的遗传学转化成技术形态的生物技术，作为一种活跃的生产力走向了产业化道路；第三，生物技术的发展充分显示新技术犹如双刃剑的两面性和对社会伦理的冲击与挑战，对社会提出了新课题。

Therefore, the 3S technologies are fully applied in the area. On one hand, remote sensing mapping and digital elevation modeling are used to realize highprecision seismic data acquisition and quality control of field operation. GPS control points are emplaced through "firstorder control, survey grid placement stepbystep and overall adjustment", and surface fitting technique is used to build a digital model with regional height anomaly corrected. The GPS RTK and fullstationequipment traverse survey are used to realize the lofting survey of shooting and receiving points. The height fitting of shooting and receiving points of the GPS RTK survey is realized through correcting the digital model with regional height anomaly.
