It is shown that there are plenty of ultramicropores (width less than 0.7 nm) in the ACF, which make ACF having the function of molecular sieve, and the pore size distribution of ACF becomes wider with increasing surface area.

研究表明ACFs含有大量的小于0.7 nm的极微孔，这些极微孔对吸附等温线的贡献较大，并且在吸附过程中赋予ACFs分子筛特性。

The study shows that the activation energy of most shell is 1/3-2/3 of the limestone, the product-layer coefficient magnitude is 1 magnitude higher than that of limestone, and the specific surface area, specific pore volume, and the average pore radius are all bigger than that of limestone. So shells are fit for coal combustion sulfur retention in high temperature (900-1000℃).

贝壳与石灰石的比较性实验表明：大部分贝壳的固硫反应活化能是石灰石的1／3-2／3，产物层扩散系数比石灰石高出一个数量级，内部微观结构如比表面积、比孔容、最可几孔半径等都比石灰石大，贝壳更适合作高温（900℃-1000℃）下的燃煤固硫剂。

This design utilizes a horizontal cylindrical screen plate with round holes up to 3mm in diameter, depending on service.

设计采用水平安放最大可达3mm直径的筛孔（孔大小根据实际情况而定）的圆形筛板。

From all of the above, UV Resonance Raman spectrum, as a new spectroscopic technique, is very helpful for us to further understand of structure and crystallization process of zeolites.

综上所述，紫外共振拉曼光谱作为一项新兴的谱学技术，对于我们深入研究沸石的结构和微孔材料的晶化过程大有帮助，会成为我们更好地研究微孔材料的得力工具。

A new advanced blasting technique in China, delay in hole and sequence out hole blasting technique, was adopted in underwater blasting excavation of guide ditch ahead of water conveyance tunnel at Xiaowan Hydropower Station, thereby the controlling aim of high explosive rate and low single dynamite weight was achieved, the maximal particle vibration velocity was controlled in allowable range, guaranteed the safety of Cofferdam and rock dam and entrance water tower and so on, provided powerful guarantee for the successful guide water of the guide tunnel.

小湾水电站导流隧洞进口围堰堰外引渠水下爆破开挖采用了目前国内较为先进的孔内延时，孔外微差的爆破技术，整个爆破区分为多段起爆，从而达到高单耗，低单响药量的控制目的，将质点的最大振动速度控制在允许范围内，有效保证了围堰、围堰岩埂灌浆帷幕区及进水塔等建筑物的安全，为导流隧洞顺利导流提供了保证。

The force on the jet pipe in the hole jetted is analyzed, and it is indicated that the resistance on the jet pipe is the main factor influencing the feeding of jet pipe.

分析了喷管在喷孔内的受力，指出喷管在喷孔内所受的阻力是影响喷管送进的主要因素，据此调节喷管送进控制液缸控制腔的压力可控制送进速度和限制最大推力。

Therefore the feeding speed can be controlled and maximal pushing force can be restricted by regulating the pressure of the hydraulic cylinder. The flexible jet pipe advances along the jetted hole with the tractive effort of the nozzle.

喷管在喷孔内主要处于承受轴向张力状态，喷嘴对喷管的牵引作用是柔性喷管能顺着喷孔送进到较大深度的主要原因。

It is one of effective measures to guarantee success rate about multi-lateral horizontal well drilling to prevent hole collapse, coal structure and situ stresses are two main factors to effect hole forming.
