Even plants can run a fever, especially when they’re under attack by insects or disease. But unlike humans, plants can have their temperature taken from 3,000 feet away—straight up. A decade ago, adapting the infrared scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide (杀虫剂]) spraying rather than rain poison on a whole field, which invariably includes plants that don’t have pest (害虫) problems. Even better, Paley’s Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3,000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a color-coded map showing where plants were running "fevers". Farmers could then spotspray, using 40 to 70 percent less pesticide than they otherwise would. The bad news is that Paley’s company closed down in 1984, after only three years. Farmers resisted the new technology and long-term backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. "This technique can be used on 75 percent of agricultural land in the United States," says George Other of Texas A&M. Ray Jackson, who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only if Paley finds the financial backing which he failed to obtain 10 years ago. Why was this kind of technology effective
The human brain contains 10 thousand million cells and each of these may have a thousand connections. Such enormous numbers used to discourage us and cause us to dismiss the possibility of making a machine with humanlike ability, but now that we have grown used to moving forward at such a pace we can be less sure. Quite soon, in only 10 or 20 years perhaps, we will be able to assemble a machine as complex as the human brain, and if we can we will. It may then take us a long time to render it intelligent by loading in the right software (软件) or by altering the architecture but that too will happen. I think it certain that in decades, not centuries, machines of silicon (硅) will arise first to rival and then exceed their human ancestors. Once they exceed us they will be capable of their own design. In a real sense they will be able to reproduce themselves. Silicon will have ended carbon’s long control. And we will no longer be able to claim ourselves to be the finest intelligence in the known universe. As the intelligence of robots increases to match that of humans and as their cost declines through economies of scale we may use them to expand our frontiers, first on earth through their ability to withstand environments, harmful to ourselves. Thus, deserts may bloom and the ocean beds be mined. Further ahead, by a combination of the great wealth this new age will bring and the technology it will provide, the construction of a vast, mancreated world in space, home to thousands or millions of people, will be within our power. A robot can be used to expand our frontiers when______.
关于限定性集合资产管理计划和非限定性资产管理计划，下列说法正确的是( )。
某建设单位经相关主管部门批准，组织某建设项目全过程总承包(即EPC模式)的公开招标工作。根据实际情况和建设单位要求，该工程工期定为2年，考虑到各种因素的影响，决定该工程在基本方案确定后即开始招标，确定的招标程序如下： (1)成立该工程招标领导机构； (2)委托招标代理机构代理招标； (3)发出投标邀请书； (4)对报名参加投标者进行资格预审，并将结果通知合格的申请投标者； (5)向所有获得投标资格的投标者发售招标文件； (6)召开投标预备会； (7)招标文件的澄清与修改； (8)建立评标组织，制定标底和评标、定标办法； (9)召开开标会议，审查投标书； (10)组织评标； (11)与合格的投标者进行质疑澄清； (12)决定中标单位； (13)发出中标通知书； (14)建设单位与中标单位签订承发包合同。 问题：指出上述招标程序中的不妥和不完善之处。 2．该工程共有7家投标人投标，在开标过程中，出现如下情况： (1)其中1家投标人的投标书没有按照招标文件的要求进行密封和加盖企业法人印章，经招标监督机构认定，该投标作无效投标处理； (2)其中1家投标人提供的企业法定代表人委托书是复印件，经招标监督机构认定，该投标作无效投标处理； (3)开标人发现剩余的5家投标人中，有1家的投标报价与标底价格相差较大，经现场商议，也作为无效投标处理。 指明以上处理是否正确，并说明原因。 3．假设该工程有效标书经评标专家的评审，其中A、B、C三家投标单位投标方案的有关参数，如表2.1所示。 若基准折现率为10%，且已知A方案寿命期年费用为72.46万元；B方案寿命期年费用为 69.93万元。试计算C方案寿命期年费用，并利用年费用指标对三个投标方案的优劣进行排序(小数点后保留两位)。 4．建设单位从建设项目投资控制角度考虑，倾向于采用固定总价合同。固定总价合同具有什么特点
