    • A process for synthesizing material uses an exothermic reactor which comprises a coolant shell, two concentric pipes provided within the shell, a catalyst bed packed between inner and outer ones of the concentric pipes, an introduction tube connected to the inner pipe through which a starting fluid is introduced, and a communication path enabling the fluid after the passage of the inner pipe to be passed through the catalyst bed in a direction opposite to the direction of the passage through the inner pipe, the coolant shell having an inlet and an outlet for a coolant arranged in such a way that the flow of the coolant is parallel to the flow of the fluid within the catalyst bed. The coolant on the outside and the starting fluid on the inside of the catalyst bed cools the bed in such a way as to produce a temperature distribution along the bed that follows a maximum reaction rate line (M in FIG. 1) relating the concentration of the methanol to the temperature of the starting fluid.
    • 合成材料的方法使用放热反应器,其包括冷却剂壳体,设置在壳体内的两个同心管,包含在内部和外部同心管之间的催化剂床,连接到内部管的引入管,通过该引入管,起始流体 以及能够使内管通过后的流体在与内管的通道方向相反的方向通过催化剂床的连通路径,冷却剂壳具有入口和出口, 冷却剂布置成使得冷却剂的流动平行于催化剂床内的流体的流动。 外部冷却剂和催化剂床内部的起始流体以这样的方式冷却床,以便产生沿着床的温度分布,该温度分布遵循最大反应速率线(图1中的M),其与 甲醇至起始流体的温度。

    • A plate thickness measuring method and apparatus, is provided wherein a fine pattern is projected on the front and rear surfaces of an object to be measured via object lenses oppositely provided on the front and rear surfaces of the object to be measured in its thickness. The image of the projected pattern on the object to be measured is formed via said object lenses, and the contrast of the formed pattern image is detected. Then the object lenses are moved slightly to achieve the maximum of the contrast, or to perform an automatic focusing control. The thickness of the object to be measured can then be estimated from the difference of the positions of the object lenses at which the maximum contrast, or the focused condition, are obtained.
    • 提供了一种板厚测量方法和装置,其中精细图案通过相对设置在被测量物体的前表面和后表面上的物镜在其厚度上投影在被测量物体的前表面和后表面上。 通过所述物镜形成待测物体上的投影图案的图像,并且检测形成的图案图像的对比度。 然后物镜稍微移动以达到对比度的最大值,或进行自动对焦控制。 然后可以从获得最大对比度或聚焦条件的物镜的位置的差异来估计被测量物体的厚度。
