查询词典 useful direction

The system state transition matrix is deduced, so the zero effort miss of the interceptor can he solved with numerical method under considering the earth's oblateness effect of J2. In order to make the thrust direction change smoothly and make the zero effort miss decrease quickly, the engine thrust is decomposed along the line of sight direction and perpendicular to the line of sight direction, and the distribution proportion coefficient is designed based on the required velocity gain normal to the line of the sight.

Focusing on them, author has been investigating in open country and collecting, arraging and analyzing material for one and a half year. After having done the study on the new deep prediction, author presents new opinion on the base of part of precious geological opinion .1, Xiaohe deposit direction and turn are mainly controlled by the second structure rochet vault in the back of Bigsnown mountain. It is conjectured that the axis extent with the current direction to the 180# exploring line and turn to northwest-southeast direction. During the extension, the deposit body would extend from deep to low instead from low to deep. The turning place was level corresponding to the core of rocket vault.2, There are a chain of radiate blind regmagenesis controlled by the rocket vault.

笔者针对这两个问题，通过一年半的野外实地调查和室内资料收集整理分析，在进行了新的深部找矿研究工作之后，在认同前人部分地质观点(即小河～石门坎矿带的连续是存在的)的基础之上，又提出了新的观点，即： 1、小河矿床矿体的走向及转向位置主要受大雪山背斜的次级构造火箭山穹隆控制，推测其轴线将沿现在的走向，延伸至180#勘探线附近发生转向，轴线方向逐渐转为北西——南东方向，同时矿体从由浅至深逐渐变为由深至浅的延伸状态。
