一款高性/价比的HDMI多媒体数字接口线

近年来，一种能传输高清晰数字信号的多媒体HDMI接口越来越多地使用在各种中、高档数字音像设备中，其中有HD平板电视机、兰光DVD机、HDDVD机、有线HDTV等等。而这些音像设备的HDMI输出接口和等离子、液昆彩色电视的HDMI输出接口之间都需要一根连接和传输的HDMI接口线。一根约2米长的HDMI进口接口线价位在数百元至一仟多元，而目前一台带HDMI接口的DVD或高清卫星接收机的价格仅在1500元以下，这种鞍比马贵的现象大大阻碍了消贯者们对该新技术尝试的欲望。

THE PERFORMANCE OF MT-CDMA SYSTEM IN THE PRESENCE OF CARRIER FREQUENCY OFFSET

In this letter,the sensitivity of an uplink Multi-Tone Code-Division Multiple Access (MT-CDMA) system to the Carrier Frequency Offset (CFO) is investigated. The analytical expression for the Bit Error Rate (BER) of uplink MT-CDMA in the presence of CFO is derived in a multipath Rayleigh fading channel which is verified through simulations. Both Maximal Ratio Combining (MRC) and Equal Gain Combining (EGC) are considered in combining multipath signals in the analysis. It is found that the BER performance can be improved with the number of multipath increasing in the presence of CFO.

One-pot three-component synthesis of tetrahydrobenzo[b]pyrans catalyzed by cost-effective ionic liquid in aqueous medium

A simple and ef ficient method is proposed for the synthesis of tetrahydrobenzo[b]pyrans with aromatic aldehydes, active methylene compounds, and dimedone using basic ionic liquid catalyst in water. The procedure offers several advantages including short reaction time, good yield, easy procedure, and good recyclability of catalysts, which may be a practical alternative to conventional processes for preparation of 4-hpyrans.

On the Status quo and Development Trends of Imported Grape Wine in China

At the present stage, The imported grape wine in China have hot market, imports increased year by year, high gross mar-gins, many brands, uneven quality, low market confidence, the price value of large deviations, imperfect legislation, regulatory confusion and so on characters. The relevant departments and units should actively take a number of measures to improve the market of imported grape wine stably and healthy development. Believe in the future, its imports would continue to grow, the gross profit margin gradually would return to rational, the cost-effective products would be prevailing, the sales channels would be diversification, the enterprises in-volved would increase, and the industry competition would become increasingly fierce.

Improvement Methods for Genetic Evaluation of Hanwoo Cows

A total of 1,101 heads were used to improve the selection of superior cows in Gangwon regional Hanwoo. Characteristics of each cow were analyzed using ultrasound evaluation and trace of reproductive potential. A comparison of live carcass traits classified by parity was analyzed in all characteristics. The results of the comparison showed all characteristic increased rapidly after the 2nd parity, and decreased after the 4th parity （P 〈 0.01）. The result of comparison classified by the group showed a tendency, whereas Back Fat Thickness Ultrasound （BFTU） and P8 Fat Thickness Ultrasound （P8-FTU） were significant （P 〈 0.01） thinnest in Pedigree group and using a lot of reproduction in advanced group. Also, we made comparisons of the cow＇s calves on the carcass traits among the group. High quality calves of the pedigree group showed 30.77%. These are the highest carcass traits in meat quality grade above 1＋ and yield grade above A. Frequency of fertilization failure per rump fat thickness showed a significantly （P 〈 0.0｜） higher difference. The average frequency of fertilization failure demonstrated 1.11 times of experimental Hanwoo cows. In the analysis, frequency of fertilization failure appeared 0.9 times at rump fat thickness below 5 mm. However, it is higher than average above 5 mm. The result of the study will be used to improve cows, select optimum semen, as well as contribute to the improvement of farms income.

A new evaluation system for early and successful conservative treatment for acute ischial tuberosity avulsion

In this report we analyse a case of ischi- atic tuberosity avulsion. A 15-year-old patient who came to our first aid department two days after a football match ac- cident was treated conservatively and examined at month 1- 4, 6 and 12. In order to examine patient condition, a new index was formulated： the inability score index （ISI）, which is based on hip range of motion and scales for rest, walking, running pain and compared to other parameters such as oedema area, fragment diastasis evaluated by X-ray and CT accordingly. ISI defines the inability as severe, moderate and mild. It guides the rehabilitative program in the right way. In this case, the patient was able to run softly after 35 days and to go back to the full agonist activity after 4 months. At the end of treatment the patient referred to the complete pain remission, full range of motion recovery and a good fracture consolidation. After 1 year we discuss about thera- peutic strategies used and results obtained.

Assessment of effectiveness of nature reserves on the Tibetan Plateau based on net primary production and the large sample comparison method

Twenty-one typical coupled large samples were chosen from areas within and surrounding nature reserves on the Tibetan Plateau using the large sample comparison method(LSCM).To evaluate the effectiveness of the nature reserves in protecting the ecological environment,the alpine grassland net primary production(NPP) of these coupled samples were compared and the differences between them before and after their establishment as protected areas were analyzed.The results showed that:(1) With respect to the alpine grassland NPP,the ecological and environmental conditions of most nature reserves were more fragile than those of the surrounding areas and also lower than the average values for the Tibetan Plateau.(2) Of the 11 typical nature reserves selected,the positive trend in the NPP for Manzetang was the most significant,whereas there was no obvious trend in Taxkorgan.With the exception of Selincuo,the annual NPP growth rate in the nature reserves covered by alpine meadow and wetland was higher than that in nature reserves consisting of alpine steppe and alpine desert.(3) There were notable findings in 21 typical coupled samples:(a) After the establishment of the nature reserves,the annual rate of increase in the NPP in 76% of samples inside nature reserves and 82% of samples inside national nature reserves was higher than that of the corresponding samples outside nature reserves.(b) The effectiveness of ecological protection of the Mid-Kunlun,Changshagongma,Zoige and Selincuo(Selin Co) nature reserves was significant; the effectiveness of protection was relatively sig-nificant in most parts of the Sanjiangyuan and Qiangtang nature reserves,whereas in south-east Manzetang and north Taxkorgan the protection effectiveness was not obvious.(c) The ecological protection effectiveness was significant in nature reserves consisting of alpine meadow,but was weak in nature reserves covered by alpine steppe.This study also shows that the advantage of large sample comparison method in evaluating regional ecology change.Careful design of the samples used,to ensure comparability between the samples,is crucial to the success of this LSCM.

The introduction of therapeutic equivalence evaluation codes and its influence on the selection of the reference listed drugs in China

The Approved Drug Products with Therapeutic Equivalence Evaluations(commonly known as the Orange Book)includes the products approved by Food and Drug Administration(FDA)to be marketed in the USA,and it is an essential source for the selection of suitable reference listed drugs(RLD)for a chemical generic medicinal product.The Orange Book assigns a therapeutic equivalence(TE)evaluation code for approved multisource prescription drug products to serve as public information in the area of medicinal product selection.In the present study,we introduced the TE coding system and its influence on the selection of the RLD in China by taking the Topiramate Extended-release Capsules as an example.As a result,it was suggested to determine its TE evaluation code in the Orange Book previously when we choose an RLD and select suitable RLD the first letter of whose TE evaluation code is A to carry out the research and development of a generic medicinal product,which can improve the probability of success of clinical bioequivalence(BE)test and reduce the risk of generic medicinal product development.
