Then the author analyzes empirically China's terms of trade from 1981,and the causes of the change in the net barter terms of trade by means of regression analysis ,which can be quantitied.we get the results that China's net barter terms of trade had a declining trend while its income terms and factorial terms of trade had been improved,and the net barter terms of trade positively correlates with actual tariff rate,exchange rate and negatively correlates with GDP,besides,the factors which can not be quantitied such as pure price fighting,inappropiate tariff sytem,foreign-invested enterprises's tranfer pricing and region trade agreement also lead to the above trend of China's net barter terms of trade,and the change in China's net barter terms of trade had a neglect impact on international trade benefit.

得出中国价格贸易条件总体上存在下降趋势，收入、要素条件呈现改善的趋势；实际关税率、汇率与价格贸易条件存在正相关关系，GDP指数与其负相关。出口企业恶性价格竞争、不合理的关税体制、外资企业的转移定价、区域贸易集团是造成中国价格贸易条件下降的非量化因素。此外，本文分析了1981-2004年价格贸易条件变动导致的中国国际贸易利益变化，发现价格贸易条件变动对中国国际贸易利益产生了一定的负面影响。最后，本文在分析中国价格贸易条件变动环境的基础上，认为中国工业化阶段不高、贸易限制性政策实施空间的减小、&合成谬误&现象及知识经济时代的到来会在一定时期内对价格贸易条件变动不利。

Can modify whole station program namely at most, 2007, I did my individual website, content of it doesn't matter, the page is simple, do not have discharge at all, because do not have time, also not was in charge of a website all the time, 08 year arrived, I have enough time bubble to be on the net, begin to care the station that has me to come, made the best of time to arrange the website one time, made some of self-help chain, sent dot rubbish to stick promotion to other forum, ah, do not see effect, wander in a few Ip everyday, really pained, the night of Yuanxiao, a person is dull, net of all night on preparation, admire to comparative on the net according to the door in the discovery on the net innocently fire, I had not heard of this thing before, do not follow to go up tide, do not have method ~~, one is searched on the net, stick in Baidu good found a few pieces of relevant pictures not easily, ah, stick to my forum immediately.

顶多就是能修改一下整站程序，2007年，我做了我的个人网站，没什么内容，页面简单，根本没流量，由于没时间，也就一直没管网站，08 年到了，我有充足的时间泡在网上，开始关心起我的站来，抓紧时间把网站整理了一番，做了些自助链，到其他论坛发了点垃圾贴推广，呵呵，不见成效，天天徘徊在几十个ip，真是苦恼，元宵之夜，一个人无聊，预备上通宵网，无意在网上发现&艳照门&在网上相当火，之前我还没听说这事，跟不上潮流，没办法~~，在网上搜索了一把，在百度贴吧好不轻易找到了几张相关图片，呵呵，马上贴到我的论坛上。

Larches of different ages have different net photosynthetic rate: the photosynthetic capacity of the young ones are bigger than that of the old ones; the stand density do not affect the net photosynthetic rate obviously; as far as the different stand classes are concerned, the diurnal changes of net photosynthetic rate is closely related to the photosynthetic active radiation. For the different layers of the crowns, there are greater ecological factors (illumination intensity, temperature, humidity etc.) on the upper layers than on the lower layers: the CO2 concentration of the lower layers is greater than that of the upper layers, which is indeed an exception; the net photosynthetic rate on the upper layers of the crown is generally greater than that of the lower layers. It showed that the CO2 concentration is not a main factor in the natural changing range of the CO2 concentration. Different directions of the crown have different photosynthetic active radiation, which is generally like exposed to the sun﹥North﹥in the shade of crown. However, the changes of net photosynthetic rate are not quite the same, which is North﹥exposed to the sun﹥in the shade of crown.

不同年龄的兴安落叶松净光合速率不同，年龄小的个体光合能力高于年龄大的个体；群团密度与净光合速率没有显著的相关关系；而对不同分级木，净光合速率日进程变化规律与光合有效辐射有着密切的联系；林内树冠不同层次各生态因子有上层大于下层的趋势，而CO2浓度在下层的含量高于上层，净光合速率上层普遍大于下层，说明在林内自然CO2浓度变幅内，CO2浓度不是主要因子；兴安落叶松树冠不同方向的光合有效辐射不同，一般向阳﹥北向﹥背阴，而净光合速率变化有北向﹥向阳﹥背阴的趋势。
