四年周期

From 1978 to 2000, there was not σ-convergence of the PGDP growth in Jiangsu province; From 1984 to 1993 and since 1999, there was not σ-convergence of the per capital net income of rural households growth, but from 1993 to 1999, there was a -convergence; From 1978 to 2000, there was not absolute β-convergence of the PGDP growth in Jiangsu province, but there was conditional β-convergence and the convergence intensity was feeble, half-lifecycle is comparative long, the least half -time of the undeveloped region will catch up with the developed region was 115 years; From 1994 to 2000, there was club-convergence hi the northern Jiangsu and the Middle Jiangsu, but there was not club-convergence in the northern Jiangsu.

第四，基于经济增长收敛的理论与方法，对江苏省区域经济发展的收敛性进行了研究。1978一2000年，江苏省人均GDP总体上不存在u一收敛；农民人均纯收入增长在1 984一1993年及1999年以后不存在a一收敛、在1993一1999期间存在a一收敛；1978-2 000年，人均GDP增长总体上不存在绝对p一收敛，但存在条件p一收敛，收敛的程度较弱，半生命周期比较长，落后区域要缩小与发达区域经济差异的一半最少也需要115年；1 994一2000年，在经济比较发达的苏南和苏中内部存在俱乐部收敛，在苏北内部不存在俱乐部收敛趋势。

隐斑瓢虫是近年来在杭州地区发现的日本松干蚧的一种重要捕食性天敌。该虫在杭州一年发生四代，其年发生规律基本上和日本松干蚧的生活周期相吻合，而且能在松林中形成比较稳定的群落。

This four-year cycle known as the "special Olympia."

这四年的周期称为"奥林匹亚特"。

Yes, that is, the cyclical nature and the earth elements have been proved to the world four times as the "Periodic Law Update"- the cycle stability of powerful, updated once every 5125 times Nian, update reflects all kinds of disasters in human eyes Pianshi.

有的，那就是元素的周期本质和地球已经像世界证明过四次的"更新周期律"——这个周期稳定的厉害，每5125年遍更新一次，更新体现在人类眼中便是种种灾难。

When we give the MBA class of prelection, there is a special dedicated to talk about this question, I, a lot of respect, General Manager, ask a lot of details, because this is really do your homework, a wise man from a bank loan of one million a year turnover per a cycle can be made his money in a eucycle State, stupid managers have banks'loans million a year turnover only once a year turnover and epicylic four times a year profit obviously different financial controls in effect we control risk, is to make profits, truly profit from the book into hard cash, this is a very important aspect.

我们给MBA讲课时，有一个专题专门讲这个问题，我一下课，许多总经理就围过来，问很多很多细节问题，因为这真是做不完的家庭作业，聪明的人从银行贷款一百万，一年周转四次，每一个周期都可以使他的资金处于良性循环状态，不聪明的经理人他也从银行贷款一百万，一年只周转一次，一年周转一次和一年周转四次带来的利润显然是不同的，所以财务监控实际上是我们控制风险，是让你的盈利，真实地从帐面盈利变成真金白银，这是非常重要的环节。

The patients were divided into four groups. Group A included 48 women with previous unilateral salpingectomy. Group B included 41 patients with previous bilateral salpingectomy. Group C included 50 patients with obstruction of fallopian tube while group D included 40 patients with hydrosalpinx (without surgical procedure before). The ovarian responses to superovulation and the outcomes of IVF-ET were evaluated.

选择2006年2月至2007年6月在本中心行常规IVF-ET治疗的179例不孕患者为研究对象，共分为A、B、C、D四组，A组为48例单侧输卵管切除患者，B组为41例双侧输卵管切除患者，对照C组为50例双侧输卵管阻塞患者，对照D组为40例单侧或双侧输卵管积水患者，比较4组患者在IVF-ET周期中卵巢对控制性超排卵的反应及其结局的差异。

Project content: Chinese west, the hardware city taking hardware product, finished product, semimanufactured goods and the processing of raw material as main industrial park, project program land area 1200 mus — 1500 mus, in garden district divide into 4 districts: Produce processing district, the trade district of finished product, the trade district of raw material and the research resident district of official business, garden district program construction period is 3 years.

项目内容：中国西部五金城是以五金制品、成品、半成品、原材料加工为主体的工业园区，项目规划用地面积1200亩—1500亩，园区内分为四个区：生产加工区、成品交易区、原材料交易区、科研办公居住区，园区规划建设周期为三年。

Resultantly, the individual warm/cold events in ENSO cycle appear to be partially locked to the annual cycle, and also exhibit obvious irregularity both in amplitude and in lasting time.

本文第四章研制设计了一包含海洋表面边界层和大气辐合反馈过程的热带太平洋海气耦合异常模式，进而利用该模式对ENSO循环进行了较为真实的模拟，通过对模式ENSO循环的演变特征及其形成机制的细致分析，建立了-ENSO循环的非线性分析模式，并提出了ENSO循环形成的一种更为客观的理论，指出：1）和观测事实类似，模式ENSO循环确实涉及了三种主要时间尺度过程即LF、QB和AC，其中LF为3-4年主周期振荡，QB占总方差10～20%；2）ENSO循环的正反馈机制是不稳定海气相互作用过程，且这一不稳定过程的发展在暖态中明显强于冷态；3）ENSO循环的负反馈机制在冷暖态中表现不同，在冷态消亡过程中，这种负反馈过程主要表现为西边界反射产生的时滞效应，但在暖态消亡过程中不存在类似的时滞效应，其负反馈过程主要表现为在海气耦合不稳定充分发展时伴随的赤道两侧冷水上翻过程的加强以及非线性过程的衰减作用抑制了不稳定的发展并最终使得系统回复至冷态；4）ENSO循环的3-4年主周期振荡是一非线性系统的自激振荡现象，其形成是线性系统的本征模即准两年振荡通过非线性机制产生的周期加倍所致，其中&单向性&大气辐合反馈加热过程对其形成至关重要；5）虽然年循环过程对ENSO循环形成没有本质影响，但它可明显影响ENSO循环的具体振幅和位相，使得ENSO对季节循环有明显的&锁相&特征，并且也使得ENSO循环在振幅大小和时间长短方面呈现出明显的不规则性。

To market slumps in China, Japan and Korea. The global economic crisis is more and more

看，从1900年到2005年，有四次经济衰退阶段，非常重要的一点就是当你从这个经济周期

Their common structure and annual changing pattern of mycorhizae are as follows: Fungi infect and form endomycorrhizal structure with plants throughout the latter's grown period, and hyphae exist in the cortical cells of roots in the following four forms: Coffee-colored or yellow big peloton consisting of twisted hyphae; Dust-colored or yellow big peloton consisting of fragmentary hyphae; Colorless scattered hyphae; Orange or yellow small peloton with blurry hyphae.

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
