My baby is 5 months has not yet stand up, I also urgent, but he was 2 months when I will be when he climbed in bed, he doubled over, I do not know this has to stand up be counted, and in any case to has now been five months he has not second breakthrough, after careful observation of my husband after the baby should be like the waist is too thick, because he could have 90 degrees sideways, but did not turn over, you also have his really no way, and my friends baby 5 months when the 16 kg, has been in bed of rolling, so I think it was and build a significant relationship.

我家宝宝也是5个月还没有翻身，我也很急，不过他在2个月的时候我将他爬在床上时，他到是翻了过来，不知道这样算不算已经翻身了，反正到现在已经5个月了他还没有第二次突破，后来经过我先生的仔细观察后想宝宝应该是腰太粗，因为他早就可以90度侧身了，但是就是不翻过来，你还拿他真的没有办法，而我朋友的宝宝5个月时16斤，在床上已经滚来滚去的了，所以我想应该是和身形有相当大的关系。

Certainly have not suffered loss, Li is a former British Hong Kong government is one of Li Ka-shing is indeed business Wizards, in the case of real estate are constantly rising had considered restructuring and the transfer of assets, has bought some foreign quality assets, telecommunications companies such as Germany orange shares, the New Jersey ports, the Panama Canal shares, and Hong Kong Cyberport aggressively into the building, will tentacles stretching the transformation and upgrading of telecommunications, Li Ka-shing is the only person in his fox, and many people are of the view that is Li and the former British Hong Kong government to give them weaving a better future, a beautiful dream, and Tung took office play his body more healthy, more destructive power of the strong characteristics of this beautiful dream hit a smash, this is one is caught, the onlookers-to the real estate collapse of the responsibility of all to Mr Tung who is totally unjustified, Although Mr Tung to the mainland, Beijing has followed some acts are in the eyes of some people, but to objectively evaluate, Dong is a honest kind of person, he is inadvertently let Tianzao point that the arrival and the day is certainly coming, the night time, the more devastating losses, Originally, the intention is that Mr Tung real estate prices trend eased, and then the case now almost Shanghai, prices every quarter on a 20% increase, almost all Hong Kong people have been crazy, and just opened a new development, the stage has long been ranked team to effectively alleviate this situation, the new SAR government changed in the past starvation effect of land supply policy, a substantial increase in the level of land supply in order to stabilize high land prices, while the Yuen Long, New Territories into the new City of mass construction, the expansion of public housing, housing construction plan (equivalent to our low-cost housing, economic applicable housing), if no major accident These measures should ensure that real estate to landing, but nobody thought that 98 years of financial turmoil, Hong Kong dollar devaluation Suoluosiming gambling, but the call foul silent do real estate, stock market doing transactions, the use diversionary tactics tactical let him return home with a full load, although the SAR government have been successfully defend the Hong Kong dollar does not depreciate, but the housing market and stock market watch.

当然也有没受损失的，李嘉诚算一个，前港英政府也算一个，李嘉诚不愧是商界奇才，在房地产不断攀高的情况下就已经考虑资产的转型和转移了，先后购买了一些外国的优质资产，如德国橙电信公司的股份、新泽西的港口、巴拿马运河的股份，并大张旗鼓地投入香港数码港的建设，将触角伸进香港电信的升级改造，李嘉诚做人方面堪称是只老狐狸，很多香港人都认为，是李嘉诚和前港英政府给他们编织一个美好的前程、一个美丽的梦，而小董上台后发挥他那身体越健壮、破坏力越强的特点，将这一美丽的梦击个粉碎，这正可谓是当局者迷、旁观者清，将香港房地产崩溃的责任全部归咎于董建华身上，是完全没有道理的，虽然董建华在靠近大陆、追随北京方面有些行为在港人眼里是过了一些，但客观地评价，董是一个老实厚道的人，他只不过是无意中让那一天早一点到来，而那一天是肯定会到来的，时间越晚，损失越惨重，本来董建华的初衷是希望房地产上涨的趋势有所缓解，当时香港的情形与现在的上海差不多，房价每隔一个季度就上涨20%以上，几乎所有的港人都为之疯狂，新楼盘刚开张，台前早已排起长长的队伍，为有效地缓解这一局面，新上任的特区政府一改以往饥渴效应的土地供应政策，大幅度地增加一级土地的供应，以平抑高昂的地价，同时宣布元朗、新界等新城区进入大规模建设，扩大政府公屋、居屋营建计划（相当于我们的廉租房、经济适用住房），如果没有大的意外，这些措施应该能保证房地产的缓着陆，但谁也没想到，98年的金融风暴，索罗斯明赌港币贬值、暗里却大做不动产、股市空头交易，这一声东击西的战术让他满载而归，虽然特区政府成功地实现了捍卫港币不贬值的目标，但香港的房市、股市从那一刻起，一败涂地。

Finally, combining PDE with Differential Geometry, parametrically representing the surface, tensor based image processing techniques have been proposed, such as edge detection , morphological operation? implicitly representing the surface as the level-set of the higher dimensional function, the variational problems and partial differential equations that define maps onto the given generic surface have been discussed.
