Cadillac Model M. In 1907, Cadillac offered two distinct touring car body styles for the Model M series: the elegant Victoria Light Touring Car and this "Straight" Light Touring Car. Both were powered by the single-cylinder Cadillac engine and priced at $950, or $1,025 with a top. In 1908, three Model M Runabouts similar to this touring car were randomly selected to prove that the precision manufacturing methods employed by Cadillac guaranteed complete interchangeability of parts.

1907年，凯迪拉克品牌为旗下的M系列车型提供了两种不同的车身设计：优雅风格的四轮折蓬式车型和直线型敞蓬车，这两种车型都配备了凯迪拉克的单缸发动机，售价从 950美元到1025美元。1908年，和这款四座敞蓬车相似的三款M型小型单座敞篷车的出现充分证明，凯迪拉克品牌的精密制造工艺和标准化的零部件生产，确保了汽车零部件可在不同车型之间交替使用。

A boot-type jet trenching system is adopted which is towed by the supporting ship. It is mainly used for trenching hard sandy clay at the shoal area with water depth 0.8 m to 30 m. Diameter of the cable to be buried is up to 150 mm, and the burying depth more than 2 m. This system has advantages of simple structure, high burying speed and great trenching depth.

该系统采取滑靴型式的喷冲挖沟方式，埋缆机由母船拖曳前进，主要用于水深在0.8～30 m的滩海，底质为硬砂土和红胶泥层，埋设直径小于150 mm的电缆，埋设深度大于等于2 m。

It was shown that coal seam floor failure depth of working face 2121 was 32.5 to 5 m, approximately three times as deep as that of shallow working face(in genera l,9.15 to 12.0 m). Coal seam floor failure depth increased with mining depth. Potential risk of water inrush through coal seam floor of working face 2121 is much higher for deep mining than for shallow mining.

试验结果表明：该工作面底板破坏深度为32.5~35 m，比300 m采深以内的工作面实测深度(9.15~ 12.0 m)增加2倍以上，说明随着开采深度的增加，煤层底板采动破坏深度呈明显增大的趋势，因此，在水压和破坏深度二者同时增加的条件下，2121工作面深部煤层开采的突水危险性远远大于浅部煤层。

In third part, I discussed R0 algebra in two different aspect:(1) Defined Boole element in R0 algebra. Gave the properties of Boole element and distributive rules of Boole element about finite R0 algebra. Study the filter and the stone filter of L are filters of M.

元的分布规律：研究了民代数M的滤子和民代数M作为有界分配格（记这个有界分配格为L（MO 的滤子之间的关系，得出结论：L的极小素滤子以及 L的 Stone滤子都是 M的滤子，但 L的滤子一般不必是M的滤子。
