块强度 meaning in Chinese

bulk strength

A chaos optimum and neural network calculation model was built based on plenty of testing data of concrete intensity to cover the shortage of single bp neural network , such as slow astringency and easy torpidity
摘要依据混凝土标准试块强度检测数据，建立了混沌优化的神经网络计算模型，从而克服传统bp网络收敛速度慢、易出现麻痹现象等不足。
The purpose of this subject was solving the problem of separation on working face . it can provide feasible source for separating coal and waste and some data for the choice of machine by researching the characteristics of waste rock and charcoal , i found a way to separate irregular waste rock from charcoal . by researching the strength of the irregular rock , got a strength equation for it and decided the feasibility by contrasting the regular assaying with the irregular assaying . in addition , using the theory of statistics , i can decide the suitable number of stylebook to ensure the feasibility of the experiment
本课题主要是为了解决综采工作面煤、矸分离问题，为煤、矸破碎分选提供可行性方法，为破碎分选机提供数据资料。通过对煤、矸各种特性的研究，找出一种能解决不规则煤、矸选择性破碎分选的技术途径。对不规则自然矿块强度特性研究，找出一种计算不规则自然矿块强度公式，通过规则试件与不规则试件的比较确定出其可靠性。
