The invention provides an anhydrous hydrogen fluoride production process; reaction raw materials fluorite powder and sulfate are mixed by an external mixer and enter into a converter with jacket; hot air with the temperature of 350 DEG C to 600 DEG C is fed in the jacket; the fluorite powder and the sulfate have chemical reaction and produce hydrogen fluoride; the produced hydrogen fluoride enters into a scrubber from a furnace header to be washed; the washed hydrogen fluoride enters into an intermediate tank from a condenser, and then receives distillation and degasification to prepare the finished product anhydrous hydrogen fluoride; solid residue is emitted from a furnace tail.

本发明提供一种无水氟化氢生产工艺,反应原料萤石粉及硫酸经外混器混合后进入带有夹套的转炉,向夹套内通入350~600℃的热风,萤石粉和硫酸在发生化学反应生成氟化氢,生成的氟化氢气体由炉头进入洗涤塔进行洗涤,洗涤后的氟化氢由冷凝器进入中间槽,然后经过精馏、脱气制得成品无水氟化氢;固体残渣由炉尾排出。

This article estimates the extreme loss distribution with extreme value theory, estimates the shape parameter with HKKP estimator, which is unbiased to small sample data, selects the right threshold by selecting smallest mean square error of the estimated cumulative distribution function and empirical cumulative distribution function and based on the extreme value theory method, this article estimates the extreme loss distribution and the p-percentile operational loss under certain believe range for Chinese commercial banks, then calculates the operational risk supervise capital.

本文利用极值理论对中国商业银行操作损失极端值分布进行估计,针对尾参数估计的来用传统Hill佑计对小样本数据容易产生偏倚的情况,提出了采用Hill佑计的改进―小样本无偏估计的HKKP佑计来估计操作损失的尾参数,针对由于阈值确定不准确导致结果偏差大的情况,采用最小化估计的累计概率分布与经验累计概率分布平均平方误差的方法确定较精确的阈值,估计出给定置信水平下操作风险损失的分位数,从而使得中国商业银行操作风险监管资本的测定成为可能。

The novice makes a rank, do not do do not have meaninglessly to the term, want to do, do have simply to the term, also can call long end key word, for instance SEO, this just proves an instrument of own actual strength, but your potential client, namely old bosses, search of very few meeting this word, meet however the word that search suits him to need more, for instance SEO electron book has etc to the term, these namely the long end key word of SEO.

新手做排名,不要做无谓的无向词语,要做,就做简单的有向词语,也可以叫长尾关键字,比如SEO,这个只是证明自己实力的一个手段,但是你的潜在客户,也就是大老板们,很少会搜这个词,而是会搜更适合自己需要的词,比如SEO电子书籍等等有向词语,这些也就是SEO的长尾关键字。

In control mice, mild intensity of immunoreactive staining of phosphorylated ERK1/2 was seen in the neurons of the marginal zone and the substantia gelatinosa in the caudal subnucleus of the trigeminal spinal nucleus (Sp5C).

免疫组织化学的观测表明,正常小鼠延髓尾侧亚核Ⅰ和Ⅱ层的神经元存在微弱水平的ERK1/2活性,左右侧无明显区别;尾侧亚核神经元存在高水平的磷酸化CREB。

In part two, the empirical results indicate that the predictive ability of SGT is much better than GT、ST、t and Normal distribution. SGT can correct not only fat-tailed property, but also defects the low kurtosis of GT and t distribution. For the volatility of asset return setting, the assumption of volatility of assets price is more appropriate than Normal and asymmetric distribution which was often used.

第二部分以实证结果显示偏态一般化t分配的配适能力较一般化t分配、偏态t分配、对称t分配和常态分配为佳,亦即当金融资产报酬率存在高峰态与厚尾现象时,偏态一般化t分配不仅可以解决常态分配所无法捕捉到的厚尾现象,亦可修正一般化t分配与对称t分配无偏态的缺点,对於资产报酬率波动性之设定,比过去常使用的常态分配与对称的分配更为适当。

The mice in experimental group and control group were exposed to 350 cGy radiation produced by 60Co. After 3 h, karyocytes at different concentrations in the fresh human umbilical cord blood were injected into the mice in experimental group A, B, C via their tail veins, and the equal volume of normal sodium was also injected into control group via tail veins. After one month, carbon tetrachloride (CCl4) was injected into experimental group A, B and control group via abdominal cavity, and the equal volume of normal sodium was injected into experimental group C. After two months, immunohistochemistry and reverse transcriptase polymerase chain reaction were used to detect the expressions of human cytokeratin-18 (CK18), cytokeratin-19 (CK19) and albumin in liver tissues of all mice.
