Sequential leaching experiments indicate fluorine in carbonate rock, phosphorite and Mo-Ni ore layer occurs principally in dissolvable forms: water-soluble, associated with carbonate or phosphorite, so fluorine in which rocks have high chemical mobility at surface conditions. Fluorine in siliceous rock, black shale and carbonaceous slate mainly occurs in undissolvable forms, which are inert at surface conditions.
氟在碳酸盐岩、磷块岩、钼、镍等多元素富集层及部分硅质岩中主要以水溶态、碳酸盐结合态等易溶形式存在,其在自然条件下的化学活动性强;而氟在碳质板岩、黑色页岩及大部分硅质岩中主要存在于难溶矿物中,其化学活动性较弱。

Based on the evaluation of rock mechanics properties of undrilling formation, a fuzzy optimization model for selecting the best similar layers with the same rock mechanics properties was established by applying theory of fuzzy optimization. Firstly the best similar layer located the undrilled area was chosen by the model. Secondly the performance of the bit used in the selected layer was evaluated by economic benefit index.
该方法在待钻地层岩石力学性质评价的基础上,首先应用模糊优选理论建立了地层岩石力学性质相似层位的模糊优选模型,用其进行相似层位的优选,然后应用经济效益指数法对相似层位的钻头性能进行评价,最后给出合理的钻头选型结果。

The network seepage flow analysis method of rock masses is a numerical method compatible with Block Element Method on the basis of the assumption that the rock blocks are unpermeable while the discontinuities are permeable.
岩体网络渗流分析方法是在假定岩石块体不透水、岩体中渗流仅通过结构面进行的基础上建立起来的一种与块体单元法配套的岩体渗流数值模拟方法。

I not only thought these the pure Productions of Providence for my Support, but not doubting, but that there was more in the Place, I went all over that Part of the Island, where I had been before, peering in every Corner, and under every Rock, to see for more of it, but I could not find any; at last it occur'd to my Thoughts, that I had shook a Bag of Chickens Meat out in that Place, and then the Wonder began to cease; and I must confess, my religious Thankfulness to God's Providence began to abate too upon the Discovering that all this was nothing but what was common; tho' I ought to have been as thankful for so strange and unforseen Providence, as if it had been miraculous; for it was really the Work of Providence as to me, that should order or appoint, that 10 or 12 Grains of Corn should remain unspoil'd,(when the Rats had destroy'd all the rest,) as if it had been dropt from Heaven; as also, that I should throw it out in that particular Place, where it being in the Shade of a high Rock, it sprang up immediately; whereas, if I had thrown it anywhere else, at that Time, it had been burnt up and destroy'd.
当时,我不仅认为这些谷类都是老天为了让我活命而赐给我的,并且还相信岛上其他地方一定还有。于是,我在岛上搜遍了我曾经到过的地方,每个角落,每块岩石边我都查看了一遍,想找到麦穗和稻秆,可是,再也找不到了。最后,我终于想起,我曾经有一只放鸡饲料的袋子,我把里面剩下的谷壳抖到了岩壁下。这一想,我惊异的心情一扫而光。老实说,我认为这一切都是极其平常的事,所以我对上帝的感恩之情也随之减退了。然而,对发生这样的奇迹,对意料之外的天意,我还是应该感恩戴德的。老鼠吃掉了绝大部分谷粒,而仅存的十几颗竟然没有坏掉,仿佛从天上掉下来似的,发生这样的奇迹难道不是天意又是什么呢?再说,我把这十几颗谷粒不扔在其他地方,恰恰扔在岩壁下,因而遮住了太阳,使其很快长了出来;如果丢在别处,肯定早就给太阳晒死了,这难道不是天意吗?
