In recent years, great progress has been made in synthesis, modification, and novel application of mesoporous molecular sieves.

近年来，在中孔分子筛的合成、修饰改性及催化应用方面的研究已经取得了较大进展。

However, this is not easy to do accurately in the first place, and the difficulty can be compounded by the fast tempos required for jigs and reels.

一是在3孔吸气压音，即从7压到6，当然这样做难度非常大，特别是在快速演奏时候要一步到位。

The solution: find the plunger adjustable arm or gear from the speed control rod protruding ears slot prolapse, should re-open the fuel pump is installed correctly; also check whether the cross-slot wear and tear is too large, if found dead in parked for seca column position, should be demolition of repair or replacement parts; injector should be able to check the plunger is serious wear and tear, deputy returned to the oil valve gasket is worn; demolition injector, check whether the coupling of needle stuck in the closed position, needle and the injection hole Does burning, according to test results even to repair or replace parts.

解决办法：发现柱塞调节臂或齿轮凸耳从调速拉杆槽中脱出，应拆开喷油泵重新正确安装；同时检查叉槽是否磨损过大，如发现柱塞卡死在停供位置，应拆卸进行修复或换新件；喷油无力应检查柱塞副是否严重磨损，回油阀垫圈是否磨损；拆卸喷油器，检查针阀偶件是否卡死在关闭位置，针阀与喷油孔是否烧损，根据检查结果进行修复或更换偶件。

Heat blanking process of pin axle hole of chain plate with high strength, large thickness and long circumference was introduced, and a few problems of heat blanking process were presented.

介绍强度高、厚度大、周边长的链板销轴孔的热冲裁加工以及链板热冲裁加工中的几个问题。

This article study the most three factors of influence in pre-splitting blasting , which are powder capacity per meter 、 spacing of hole and decoupling. On the basis of ANSYS/LS-DYNA and establishing 3D model about two pre-splitting holes, numerical value sumilate expanded process of the crack , then estimates effect of the rock crash by analyzing stress , otherwise estimates effect of pre-splitting blasting by expanded picture .

本文研究了预裂爆破中影响最大的三个因素：线装密度、周边眼间距及周边眼的不耦合系数，并利用动力有限元分析软件ANSYS/LS-DYNA，建立两预裂孔爆破的三维模型，数值模拟出预裂爆破裂缝扩展过程，然后通过应力值的分析来判断岩石的破碎情况，另外利用预裂缝的扩展图分析预裂爆破的效果。

Should medication,不瞒you say, my son often urine Kang spent a great deal of medicine, what Chinese medicine, prescriptions, have used the most efficacy of this method is because the prescriptions too difficult to eat , you can first try, eggs, one of seven white pepper, in egg bar a small hole above the white pepper on the inside, and then face to block the hole, on steamed bowl.

多大了？？应该用药，不瞒您说，我儿子也经常尿炕，用了不少药，什么中药，偏方，都用了，最有疗效的算是这个方法了，因为这个偏方太难吃，你可以先试一试，鸡蛋一个，白胡椒7粒，在鸡蛋上面扎一小孔，把白胡椒放在里面，然后用面把孔堵住，放在碗里蒸熟。

In this paper a finite element strength analysis and calculation for the following three types of boiler head perforated by large openings is performed with the help of a plate shell model: i.e., one without any reinforcemen...

理论与实验研究结果表明，本文建立的有限元模型用于大开孔封头强度分析是可行的，计算结果与实测吻合较好，实际应力没有超过材料的许用应力

I just needed to smooth it out a little and fit it to the boiler shell as well as bore the end a little bigger for the smoke stack.

我只需要顺利出一点和适合它的锅炉壳以及孔底有点大，为烟雾堆栈。

The boring bar was designed into a new structure consisting of two coaxial bars. As a result, the micro-boring bar can be made with relatively smaller outer diameter, which was suitable for boring smaller and deeper hole, even the measuring and compensating sensors have been incorporated.

但是，在镗削加工中就遇到了较大困难，因为镗杆的径向尺寸受到被镗孔尺寸的严格限制，用于误差在线检测的传感器和用于误差在线补偿驱动的传感器不能直接安装在镗杆内。

What would he tell Judith and the children?
