Based on a computing model of floor heating residences, indoor thermal environment and heat distribution under the effect of heat charge/discharge, operation control and solar radiation has been concluded. Concept and formula of equivalent heat supply has been put forward which indicate that actual heat supply will be equal to the sum of design heat supply and equivalent heat supply. Recommend coefficient has been given taken Dalian as an example. Computed according to the new method, design heat supply can be reduced to 37% in cloudy day and 43.3% in sunny day, energy saving effect is very obvious. In Tromb wall solar house, effect of concrete wall on indoor temperature swing and attenuation of temperature wave is very obvious. While the outdoor air-temperature swing exceeds 10℃, indoor air-temperature swing belows 3℃. In the experiment, maximal difference in temperature between inner surface and outer surface of the 300mm wall exceeded 10℃. Heat storage and collector efficiency varies adversely according to solar radiation. Factors such as thickness, material, absorptance of the wall and permeation of the glass cover all have big influence on heat storage and collector efficiency. There exsisted an optimal thickness of the wall, which can make the best of heat storage and collector efficiency. Most of the heat stored in conventional Trombe wall during the daytime has been lost to the outside at night without heat preservation. Heat preservation on the outside surface of the wall has effectively improved heat release performance of the wall at night, heat supply to the room has increased too.

In this paper, the noise sources of the EBCCD imaging system have been analyzed and a SNR model has been established. It shows that the SNR of output image is related not only to the input illuminance on the cathode but also to the spatial frequency of the input image. This has been proved by a series of experiment. Unperfectness of the detecting equation has been pointed out in this paper.

In this study, the methodology of linear structural rela- tionship model of latent variable has been studied which is the first time in China. Some extended conclusions have been come up to, such as multi-factor congeneric measure model, the reliability of measurable variable and its hy- pothesis test, the relation between standardized solution and unstandardized solution, multidimensional path model with measure errors, and multilevel model of latent vari- able. Some examples have been shown to help apply these results in practice, such as the analyses of the children growth-development data, the bone density data and the health resources data by means of latent variable model. Not only have new explanations for these data been achieved, but also powerful patterns for applying the theoretical methods in medical sciences and other fields.

The price pricking beer is 3 5 times higher than familiar equal amounts beer , investigates whose cause to have several aspect down: One, has been fresh beer because of it , has kept fine taste of beer and nutrition; That sterile condition demands is strict among it's two , procedure of production, equipment investment is big, be going to want the strict sterility course film fliteration or hole fliteration, besides all microorganism , beer barrel and production environment before irrigating dress; It's three , marketing way have been unique , had been going carrying out the carbon dioxide cooling down and supplementing by the fact that fresh beer sells machine, have made use of carbon dioxide pressure to give beer and , have avoided beer contacting air but have produced oxide taste; It's four, has been that scheduled time is not long because of barrelled fresh beer guarantee quality , the dealer has born certain risk, if being able to not sell out in time, meeting bring about very big economic losses.

扎啤的价格比同等量的熟啤酒高3—5倍,究其原因以有下几个方面:其一,因为它是鲜啤酒,保持了啤酒良好的口味和营养;其二,生产过程中,无菌条件要求严格,设备投资大,在灌装前要经过膜过滤或孔过滤,除去所有的微生物,啤酒桶和生产环境也要严格无菌;其三,销售方式独特,要过通过鲜啤酒销售机进行降温和补充二氧化碳,并利用二氧化碳压送啤酒,避免了啤酒接触空气而产生氧化味;其四,是因为桶装鲜啤酒的保质期不长,经销商承担了一定的风险,如果不能及时售出,会造成很大的经济损失。
