Technological innovation is the development of enterprises in the last word, i have always maintained the secretary rise in special wallssevered the forefront of the core system, in 2000, the high - intensity of my invention cesium potassium glass chip. test success has been on the market seven years, 2007 to special ( fire ) glass wallsindoor fire glass partition, fire glass window design, construction and 10 years of deep - processing glass curtain wall designconstruction and constantly sum up experience and experiment, glass walls severed system to fire. high temperature must be within the framework of anti - bomb material support fixed glass in the event of fire. at the time of the explosion have enough time to ensure the integrity of the entire system. bullet - proof glass or glass does not fire in a short period of time due to damage fixed framework, a glass panel fell off, lost the fire or bomb - functional
企業不斷的技術創新是我們發展的硬道理，也是我司一直保持林立於特種幕墻、隔斷系統前沿的核心， 2000年，我司發明的高強度單片銫鉀防火玻璃，經試驗檢測成功推向市場以來已有7個年頭，七年來特種（防火）玻璃幕墻、室內防火玻璃隔斷、防火玻璃門窗的設計、施工及十多年來的玻璃深加工，幕墻設計、施工及不斷的經驗總結和試驗，玻璃幕墻、隔斷系統要防火、防炸彈沖擊波必須要有耐高溫高強度的框架材料固定支撐玻璃，在一旦發生火災、爆炸的時候要有足夠的時間保證整個系統的完整性，不至於防火玻璃或防炸彈玻璃在短時間內由於固定框架破壞，而玻璃脫落，失去了防火或防炸彈的功能。 -
( 三 ) under the dynamic load of the explosion, the numeric analysis has been done and achieve the rule as follow : ( 1 ) when the frequency of vibration is 0. 3hz, the acceleration of the slopes top gets the maximum ; so 0. 3hz is believed the natural frequency of the slope as a whole ; ( 2 ) the vibration of explosion can been magnified because of the condition of the landform, when the relative altitude is up to 45m, the acceleration of horizon gets the maximum ; when the relative altitude is up to 100m, the absolute value of acceleration and the deformation of horizon is larger than that in the bottom of the slope ; ( 3 ) in the period of forced vibration, at the top of the slope, the acceleration of horizon become larger and larger ; at the middle part of the slope, it becomes smaller ; ( 4 ) when the explosion velocity of is much little, the shallow part destruction is the primary deformation of the slope
（三）採用模態疊加法針對爆破動力作用，進行邊坡的動力響應分析，得出了以下結論： （ 1 ）振動頻率為0 . 3hz時，坡面頂部水平向加速度峰值最大；綜合考慮，可認為該邊坡的自振頻率為0 . 3hz左右； （ 2 ）地形對爆破地振動存在放大作用，研究剖面的坡面，水平向加速度及位移在地形相對高差45米左右最大，而後隨相對高差的增高而減小，相對高差為100米時，水平向位移及加速度絕對值均大於坡腳； （ 3 ）強迫振動段，水平向加速度值隨時間變化的規律為：坡頂節點總的變化趨勢是越來越大，而坡體中部節點的變化趨勢是越來越小； （ 4 ）當爆破振速較小時，變形破壞的形式表現為坡頂表面滑塌型。 -
With the rising of gas cloud radius, the explosion pressure increases quickly during energy releasing period, and rapidly attenuates when the flammable gas burns up within gas cloud. ( 2 ) the larger the explosion heat is, the higher the maximum explosion pressure is. with the growing of explosion heat, the explosion pressure sharply increases during energy releasing period, and rapidly attenuates after the flame is distinguished within gas cloud
利用該程序計算了爆炸場參數，計算結果表明：氣雲半徑越大，爆炸最大壓力越大：氣雲半徑越大，氣雲區內部爆炸壓力在能量釋放過程中增加得越快，在能量釋放完畢以後衰減得也越快；爆熱越大，爆炸最大壓力越大；爆熱越大，氣雲區內部爆炸壓力在能量釋放過程中增加得越快，在能量釋放完畢以後衰減得也越快。 -
On the basis of the analysis on the yangtze vole ' s disaster history and condition in dongting lake area, the influence of the lake beach ' s environmental evolution on the vole disaster is studicd in this paper. the rise of low - middle - level beach area causes the vole ' s population explosion, the reduction of high - level beach area forces the voles into the farmland during the flood season, and the emergence period ' s continual increase extends the vole ' s habitat areas and forces them to migrate into the farmland. the discarded dike provides a rest place halfway for the voles, which escape the flood, and the natural enemies of the voles, which are a natural barrier against the vole ' s population expansion, decreases. according to this study, the conclusions are put for ward as follows : after three - gorge project ' s construction it will produce great influences on the beach evolution in dongting lake area, leading to the changes of the vole ' s ecological environment situation and resulting in the vole ' s population changes which deserves attention
在分析洞庭湖區東方田鼠暴發成災史及災情的基礎上，研究了洞庭湖區洲灘演變對東方田鼠暴發成災的影響.研究認為，中低位洲灘出露面積不斷增大使東方田鼠種群迅速膨脹，高位洲灘出露面積減小造成汛期東方田鼠大量向垸內農田遷移;湖區洲灘冬春季連續出露天數增加延長了東方田鼠的繁殖期;汛期洪峰水位增高，洲灘大面積淹沒迫使東方田鼠大量遷向垸內;湖內廢棄湖堤為東方田鼠逃避洪水提供了中途休養之地;洲灘地抑制東方田鼠種群膨脹的天敵數量已大大減少.據此，本文指出，三峽工程建成后將對洞庭湖區洲灘演變產生重大影響，因而將改變東方田鼠種群生態環境條件，引起種群動態變化，值得注意
