The results of interior ballistic theoretical simulationindicates that the single PSS charge application need propellants be provided with upperburning rate, adopting PSS and traditional model frame propellants commix charge is apractical applied technique approach.. By optimizing the PSS model frame parameter, wecan obtain "flat roof" domino offect with better even peak value "double peak" p-tcurve. Comparing with current 19 hole propellants charge with the best increasing burningsurface characteristic, the muzzle velocity of projectile can be enhanced about 55m/s, andthe instruct pressure efficiency can be enhanced about 5.7％.

内弹道理论模拟结果表明，PSS发射药单一装药的应用，需要发射药具有较高的燃烧速度，采用PSS发射药与传统药型的混合装药，是目前PSS发射药实际应用的技术途径，通过药型参数的优化可获得"平台"效应更好的等峰值的"双峰型"P～t曲线，与现有增面性最好的19孔发射药装药相比，弹丸初速可提高55m／s左右，示压效率高5.7％左右。

The macroprogram is written by using the elliptical parametric equation, then some actual work problem can be solved with the macroprogram.

在数控编程的实际应用中，常见的是直线插补和圆弧插补，没有椭圆插补，但在实际生产中，往往遇到许多椭圆的零件需要加工，如果手工常规编程就无法编制出椭圆的加工程序，为了解决这个问题，在数控编程中有宏程序可以做到椭圆的加工，本文按HCNC-21T系统（在其他系统只不过是宏程序的格式不同而已）对椭圆做内、外的加工编程举例，还在内椭圆的加工中先加工一个工艺孔，巧妙利用椭圆的参数方程来编写宏程序，用宏程序来解决一些实际的工作问题。

Because the strength of springwood was very low, the strength of board which included more springwood was low. The main reason why there was no difference in wet compressing shear strength between quarter-sawn board and flat-sawn board was that quarter-sawn board had a lot of pits on radial cell wall and in flat-sawn board xylary rays were transversely cut and left a lot of pores which provided a kind of tunnels for water.

造成柞木径切板的反复煮沸压缩剪切强度与弦切板的反复煮沸压缩剪切强度没有显著性差别的主要原因是柞木细胞壁径面上的纹孔很多，而弦面上的木射线在经刨削后是横断的，留下许多孔隙，这使得弦径向均有成为水分通道的孔隙，造成柞木径切板的反复煮沸压缩剪切强度与弦切板没有显著性差别。

Heretofore, the mother, while loving her child with the intensity of a soul affection, had schooled herself to hope for little other return than the waywardness of an April breeze; which spends its time in airy sport, and has its gusts of inexplicable passion, and is petulant in its best of moods, and chills oftener than caresses you, when you take it to your bosom; in requital of which misdemeanours, it will sometimes, of its own vague purpose, kiss your cheek with a kind of doubtful tenderness, and play gently with your hair, and then be gone about its other idle business, leaving a dreamy pleasure at your heart.

孔。此前，做母亲的虽以极其专一的钟爱爱著她的孩子，却总在告诫自己，且莫指望得到比任性的四月的微风更多的回报——那微风以飘渺的运动来消磨时光，具有一种难以名状的突发的激情，会在心情最好时勃然大怒，当你放它吹进怀中时，经常是给你寒气而不是爱抚；为了补偿这种过失，它有时会出於模糊的目的，以一种值得怀疑的温柔，亲吻你的面颊，轻柔地抚弄你的头发，然后便跑到一边去作别的无所事事的举动，只在你的心中留下一种梦幻
