  1. So the results indicate that the two mutants have no significant difference in the toxicity of inhibiting mammal neuron sodium channels, and ala20 or ser20 was not the key residue. the two peptide neurontoxins inhibite mammalian voltage - gated sodium channels through a novel mechanism distinct from other known spider toxins such as 5 - actxs, - agatoxins i - vi which banded receptor site 3 to slow the inactive time course of sodium channels. we suggest that hntx - v maybe target the site 1 of sodium channels in a similar manner to - conotoxins and ttx

    同時兩種海南捕鳥蛛毒素從影響ttx一s鈉通道的方式上來看，與其它已知膚類蜘蛛毒素如6一actxs等通過作用於位點3引起延緩鈉通道的失活時間存在明顯不同，我們推測hntx一iv和iintx一v可能是以一種新的不同於其它蜘蛛毒素的方式來影響鈉通道的，而ttx一s鈉通道位點1則很有可能便是它們的作用位點，與ttx和林一eonotoxins相似。
  2. It shows that the injection quantity and the difference of temperature distribute as a parabola which is at the same load, and the minimum of the parabola corresponds to the optimum quantity of injection ( g ). under the condition that the quantity of injected mass, the air speed and the heat quantity is respectively g, v and q, the research demonstrates that the pentium iv chip ' s temperature variation can be controlled under 40c and work normally when the wind speed overpass 1. 5m / s and the power dissipation of the chip is 60w. otherwise this paper calculates the flooding limit of thermosiphon with several different methods

    對其充灌量、散熱量、電子元件（ cpu模擬晶元）表面與環境溫度之差及通風、流速的影響進行了系統的測試，發現充液量與溫差的關系在負荷不變時呈拋物線分佈，其極小值點對應的充液量是最佳充液量g 。在充液量為g時，對風速v 、散熱量q進行的研究表明，當風速超過1 . 5m / s后，奔騰晶元在60w發熱條件下晶元溫度小於40 ，能滿足長期正常工作。
  3. Many foreign mathematicians have respectively devoted to researching the hamiltonian systems, boundary value problem and the oscillation, the asymptotic behavior, the stability of the dynamic equation on time scales, such as erbe l, bonnet m, peterson a, agarwal r, d sl o, kaymakcalan b, lakshmikantham v etc. in general, the research methods they used are just as the following : firstly, we compare the method of differential equation and with the corresponding difference equation, then unite them, finally, extend the results to other time scales

    近十年來，時間模上的動力學方程的研究得到了較快的發展，國外不乏有許多數學大家erbel ， bohnerm ， petersona ， agarwalr ， d slo ， kaymakcalanb ， lakshmikanthamv等都分別致力於時間模上哈密爾頓系統，時間模上動力學方程的邊值問題以及時間模上動力學方程的穩定性、振動性、漸近性等方面的研究。總的來看大家所採用的研究方法大致都是把微分方程與差分方程研究方法進行比較、統一，然後再推廣到其它時間模上。
