Such criticisms, though, would wholly miss the point of this pleasurably intelligent book, in which the butcher, the baker and the candlestick-maker of nursery rhyme give way to the chocolate-coated snack brand manager, the career counsellor, the rocket scientist, painter, accountant and vendor of warplanes.

然而，这些评价全然没有抓住这本充满了愉悦的智慧的书的要领，书中肉贩、面包师和做童谣烛台的让位给了巧克力零食的品牌经理、职业规划顾问、研究火箭的科学家、画家、会计和军用机的供应商。

Through the research into vibration of large liquid rockets, this paper explains the theoretical analysis and testing techniques of POGO vibration, and the means the designer should consider to prevent POGO vibration.

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。
