The symbolic-Lyapunov index can be used to identify the different condition of piston ring sticking of diesel.

因此，符号李指数能够用于辨识柴油机不同的活塞环胶结状态。

The high cost of powder flexible putty results in the high cost of the admixed latex powder that contains unbonding talcum powder and powdered whiting, besides fulfilling the performance of powder flexible putty requires high content of latex p.

粉状柔性腻子产品成本较高的原因是乳胶粉的成本高，除了直接成本外，乳胶粉中还含有一定量无胶结性能的滑石粉、重质碳酸钙等，使之用量必须很高才能满足性能需要；适合柔性腻子的产品类型是由液料和粉料组成的双组分腻子，该类腻子在满足JG158—2004标准要求的情况下，具有合理的成本，完全能够为市场接受。

The High-Water-Content and Quick-Setting Materials are a new kind of cement with many unique properties: 1. high water content. 2. quick setting and strengthening. 3. long pumpability time. 4. good mechanical properties. 5. the property of re-developing strengthen after ultimate loading.

高水速凝材料是为适应煤炭开采技术的发展需要而研制出的一种新型固体胶结材料，它具有许多独特的优点：①水用量大；②速凝早强：③可泵时间长；④良好的塑性特性；⑤极限荷载后强度再发展性能。

Through electron micrograph, sepiolite is found to have net fiber structure shaped by straw bundle.

海泡石一超细水泥的实验看出，超细水泥具有粒径小、比表面积大、水化速度快的特点，在加入海泡石后，海泡石并没有对超细水泥的水化速度产生很大的影响，能够使超细水泥的一些施工性能得到更好的改善，同样对超细水泥的胶结强度、抗折强度、抗冲击韧性起到提升的作用。

Effect of sodium sulfate, with a dosage of 1 % and 2 % to blender respectively, on autogenous shrinkage and cracking of fresh concrete were investigated.

研究了分别掺加占胶结料质量分数1 %，2 %的硫酸钠对混凝土早期收缩开裂的影响。

Check for proper tappet clearance, for sticking, and air leaks.

检查适合的挺杆间隙，气门胶结，和漏气

A new type of hydraulic pulse vibration generator installed at bottom of casing strings was developed.

研制了新型水力脉冲振动注水泥装置，该装置安装在套管底部，在注水泥过程中产生水力冲击作用于套管、水泥浆和钻井液，通过消除气泡、清除泥饼、提高顶替效率和水泥石强度来提高水泥胶结质量。

During waterflood development,for the effect of injecting water on reservoir pores, framework grains, adglutinate and reservoir fluids, high-capacity channel s are come into being easily in formation.

在注水开发过程中，注入水对储层孔隙、骨架颗粒、胶结物和油藏流体的作用等因素的影响，易在储层中形成大孔道。
