发布时间：2020-11-21
今天我们来讲解一下研究生数学考试是否可以携带计算器，不了解的小伙伴们赶紧看过来，希望可以帮助到大家。
硕士研究生考试准考证上并未注明允许携带计算器的考生，不能带入计算器。
考生应按考点所在省级教育招生考试机构有关规定携带并使用文具。自命题科目按招生单位说明携带文具。

下面我们来了解一下研究生免考申请程序，如下：
1、考生申请免试资格，首先需要登陆招生院校研究生招生网查询这所学校的招生简章，并仔细阅读简章内容，下载该学校免试申请表，并于规定的时间内将填写好的申请表和申请材料寄送到该校招生办公室进行初审。
2、申请材料经招生院校招生办公室审核后，符合条件的申请人将被通知到该学校进行复试。具体的复试时间请各位考生以院校公布的时间为准。
3、对通过复试并同意接收的应届本科毕业生，由招生院校研究生招生办公室发出拟接收函。收到拟接收函的同学须在规定时间内办理正式网上报名手续，并将入学所需材料寄往招生院校的研究生招生办公室，未在规定时间内按照流程办理网上报名手续者被视为放弃录取。
4、申请免试的考生务必准确填写真实信息，如发现申请人提供虚假的信息和材料，将取消申请人免试资格。

“The ancient Hawaiians were astronomers,”wrote Queen Liliuokalani,Hawaii's last reigning monarch,in 1897.Star watchers were among the most esteemed members of Hawaiian society.Sadly,all is not well with astronomy in Hawaii today.Protests have erupted over construction of the Thirty Meter Telescope（TMT）,a giant observatory that promises to revolutionize humanity's view of the cosmos.
At issue is the TMT's planned location on Mauna Kea,a dormant volcano worshiped by some Hawaiians as the piko,that connects the Hawaiian Islands to the heavens.But Mauna Kea is also home to some of the world's most powerful telescopes.Rested in the Pacific Ocean,Mauna Kea's peak rises above the bulk of our planet's dense atmosphere,where conditions allow telescopes to obtain images of unsurpassed clarity.
Opposition to telescopes on Mauna Kea is nothing new.A small but vocal group of Hawaiians and environmentalists have long viewed their presence as disrespect far sacred land and a painful reminder of the occupation of what was once a sovereign nation.Some blame for the current controversy belongs to astronomers.In their eagerness to build bigger telescopes,they forgot that science is not the only way of understanding the world.They did not always prioritize the protection of Mauna Kea's fragile ecosystems or its holiness to the islands'inhabitants.Hawaiian culture is not a relic of the past；it is a living culture undergoing a renaissance today.
Yet science has a cultural history,too,with roots going back to the dawn of civilization.The same curiosity to find what lies beyond the horizon that first brought early Polynesians to Hawaii's shores inspires astronomers today to explore the heavens.Calls to disassemble all telescopes on Mauna Kea or to ban future development there ignore the reality that astronomy and Hawaiian culture both seek to answer big questions about who we are,where we come from and where we are going.Perhaps that is why we explore the starry skies,as if answering a primal calling to know ourselves and our true ancestral homes.
The astronomy community is making compromises to change its use of Mauna Kea.The TMT site was chosen to minimize the telescope’s visibility around the island and to avoid archaeological and environmental impact.To limit the number of telescopes on Mauna Kea,old ones will be removed at the end of their lifetimes and their sites returned to a natural state.There is no reason why everyone cannot be welcomed on Mauna Kea to embrace their cultural heritage and to study the stars.
It can be inferred from Paragraph 5 that progress in today’s astronomy____

A.is fulfilling the dreams of ancient Hawaiians.
B.helps spread Hawaiian culture across the world.
C.may uncover the origin of Hawaiian culture.
D.will eventually soften Hawaiians’hostility.
B.helps spread Hawaiian culture across the world.
C.may uncover the origin of Hawaiian culture.
D.will eventually soften Hawaiians’hostility.
答案：C
解析：
推理判断题。根据题干可以得知该题为段落推理题，段落推理题一般考查段落主旨。一般而言，反复提及的信息一定和段落主旨相关，我们可以看到本段话中反复提到的是culture，而包含culture的选项只有B和C,B选项spread Hawaiian culture文中并未提及，而从最后两句话中可以看到astronomy and Hawaiian culture both seek to answer big questions about who we are,where we come from and where we are going.C选项中的uncover对应原文中seek to answer，origin对应的就是about who we are,where we come from and where we are going，故选项C may uncover the origin of Hawaiian culture为正确答案。

试论述古诺模型的主要内容和结论
答案：
解析：
(1)古诺模型假设：第一，两个寡头厂商都是对方行为的消极的追随者，也就是说，每一个厂商都是在对方确定了利润最大化的产量的前提下，再根据留给自己的市场需求份额来决定自己的利润最大化的产量；第二，市场的需求曲线是线性的，而且两个厂商都准确地知道市场的需求情况；第三，两个厂商生产和销售相同的产品，而且生产成本为零，于是，它们所追求的利润最大化目标也就成了追求收益最大化的目标。 (2)在(1)的假设条件下，令市场容量或机会产量为Q，则每个寡头厂商的均衡产量为1/3Q，行业的均衡总产量为2/3Q。如果将以上结论推广到m个寡头厂商的场合，则每个寡头厂商的均衡产量为1Q/(m+1)，行业的均衡总产量为mQ/(M+1)。 (3)在关于古诺模型的计算题中，关键要求很好地理解并运用每一个寡头厂商的反应函数：首先，从每个寡头厂商的各自追求利润最大化的行为模型中求出每个厂商的反应函数。所谓反应函数，就是每一个厂商的最优产量都是其他厂商产量的函数，即Qi=f(Qi)，ij=1、2，i≠j。然后，将所有厂商的反应函数联立成一个方程组，并求解多个厂商的产量。最后，所求出的多个厂商的产量就是古诺模型的均衡解，它一定满足(2)中关于古诺模型一般解的要求。在整个古诺模型的求解过程中，始终体现了该模型对于单个厂商的行为假设：每一个厂商都是消极地以自己的产量去适应对方已确定的利润最大化的产量。
