Its tunable wave - region is over 100nm ( 701 812nm ) with the characteristics of simple manufacture and compact structure ; pulse with high energy can be obtained through q - switch for longer life ( 260us ) particles in upper level in this paper, tunable and q - switch mechanism and principle of working material alexandrite ( cr3 + : beal204 ) is firstly expatiated and analyzed. the experiment of tenability ( et ) and experiment of q - switch ( eq ) is proved feasible
該激光器波長在701 - 826nm之間，製作容易，結構緊湊；上能級粒子壽命長（ 260 s ） 、調q容易得到大能量輸出本論文首先對激光工作物質?紫翠寶石（ cr ~ （ 3 + ） ： beal _ 2o _ 4 ）的調諧與調q原理和機制進行了解釋與分析，確定了調諧與調q實驗的可行性。 -
The fusion protein was bactericidal active against staphylococcus aureus. in present study, we will truncate the none channel - forming do main, then attach the agrd to the pore - forming region ( k544 - i626 ) to construct a new engineered multidqmain protein machine - compact engineered peptide targeting staphylococcus aureus. such engineered peptide was constructed by linking the gene of staphylococcal agrd pheromone with the gene of c - terminal ( 1626 ) of colicin la pore - forming region ( k544 - i626 ) with site - directed mutation
利用點突變方法將金黃色葡萄球菌信息素agrd （ i型， ystcdfim ）的基因引入到大腸菌素fa梭基端1626基因上，並將限制性內切酶sacl酶切位點基因分別引入到大腸菌素fa的p4和k544上，通過酶切、膠回收、連接獲得含大腸菌素ia水性孔道結構域和金黃色葡萄球菌信息素agrd基因的重組質粒。 -
At first, an integer construction principle is built including the integer harmonious principle on the region lay, the compact and whole principle of good city form on the community lay, suitable density and fit plot area, the humanness principle that incarnates man being principal part in the community, attitude to traditional town and traditional architecture etc. afterwards, some problems about the organization framework of
首先，我們確立了一個整體建構原則。包含區域層面上的整體協調原則，社區層面上的緊湊、整體的城市形態原則，適當的密度和適合的用地規模，社區中「人」的主體地位的人性化原則，對我國傳統的城鎮與傳統建築類型採取的態度等幾個方面的內容。 -
The liquid - phase synthetic method was improved to obtain the sedimentation of yvo4, which makes the procedure more convenient and the sedimentation more compact. based on the syntheses of the raw materials, the czochralski method was used to grow the crystal from different charges. by comparing with the spectrum in the ultra - violet region of the yvo4 crystals grown in the same condition, the result was reached that the presence of the 1552 absorption peak is independent of the direction of the crystal growth and the annealing, but is related to the impurity of the charges
採用多種方法合成了用於晶體生長的yvo _ 4原料，改進了液相合成法中獲得yvo _ 4沉澱的方法，使得該方法更為簡便，獲得的沉澱更加緻密；在原料合成的基礎上，採用提拉法對來源不同的生長原料進行了生長，並通過對在相同氣氛下生長的晶體的紫外透過譜線的對比，指出了該吸收峰的存在與晶體生長方向及有無退火無關，進而提出該吸收峰的存在與合成原料中有無雜質有關。 -
The fourth - order explicit upwind - biased compact difference schemes are used in the spatial discretization of the nonlinear convection terms. these difference schemes can be used in all computational region including the boundary neighborhood, and can overcome the difficulty not adapting simultaneously in the boundary neighborhood for general three - dimensional fourth - order central difference schemes, and improve computational stability a nd resolution. the compact difference equations with high accuracy and resolution for solving the incompressible n - s equations and perturbation equations are composed of these compact difference schemes, and provides an effective numerical method for the investigations of the turbulent spots and coherent structures
文中發展了四階時間分裂法用於navier - stokes方程及其擾動方程的時間離散；對分裂得出的關于壓力的poisson方程和關于速度的helmholtz方程，建立三維耦合四階緊致迎風差分格式；這些格式適用於包括鄰近邊界點在內的計算區域，克服了三維各自用四階中心差分格式離散不適用於邊界鄰域的困難，並提高了穩定性和解析度，用這些格式分別組成了數值求解navier - stokes方程及其擾動方程的高精度、高解析度的緊致差分方程組，為湍斑及湍流相干結構的研究提供了有效的數值方法。
