This method can analyze diesel oil additive whose efficacy is unknown. It only takes some simple physical property tests of the diesel oil samples added unevaluated diesel oil additive or a kind of known better diesel oil additive to do the grey relation analysis and evaluate the unevaluated additive.

Main contents and conclusions are: 1 The ionization current was measured continuously by a charge-integration method with a computer after the introduction of radon into the chamber.

主要内容及结论：1充氡后利用计算机连续进行电离电流累积测量，得到了精细的电流随时间的变化曲线，可清楚看出氡及其子体的生成衰变造成的电离电流的生长—稳定—衰减过程，与理论计算值进行了比较，由电离电流衰减速度的变化得出氡吸附作用的影响，并测量到电离室冲洗后氡的反扩散现象；2由已知活度的标准源定出相对测量的刻度系数K值，K=24.62 Bq／pA，对同一个监测源以半年为周期进行多次测量后得出稳定性符合要求；3通过测量电离电流和气压的关系曲线以及不同气压下的饱和曲线，确定了常规的工作条件；4测量了盐酸清洗电离室内表面降低本底的效果；5不确定度分析表明相对测氡的扩展不确定度(k=2)小于5％，由本底涨落得出探测下限为0.5 Bq；6理论上对壁损失修正进行了计算，实验上保持电离室工作在饱和区的情况下，测量了不同气压下电离电流的变化，从中得出了壁损失随气压变化的规律，可以看出，电离电流的实测值和计算值随气压变化规律基本一致；当气压大于125 kPa时，端效应等其它因素造成的影响不大于2％，因而在此工作条件下，测量电离电流后通过计算修正壁损失可以实现近似的绝对测氡，提出了进一步提高绝对测量准确度的方法。

The amplified band from M131 was sequenced and then aligned with the sequence of avr-Pila gene. The result was that the sequence was 98% homologous to one fragment of avr-Pita sequence, but the integration site was not within this fragment.

将M131的扩增片段测序后得到长度为1057bp的序列，并且将所测序列和已知的avr-Pita一段序列比较发现达98％的同源，即该序列为无毒基因的某一段序列，但插入的位点并不在所扩增片段内。

This model based on the idea of Heisenberg's Uncertainty Principle, which states that we do not know the precise location or the velocity of any given electron.

这个模型基于海森堡的测不准原理，测不准原理声明我们不知道任何已知的电子的精确位置或速度。

The study results showed that Pomacentridae and Labridae are the two most dominant families and the Pomacentrus coelestis is the most abundant species during day time. Species composition of coral reef fish assemblages at the four stations changed more or less each year. The Sorensen similarity values of the four stations fluctuated between 60-75%, fluctuation is mainly due to the changes in rare species.

其结果目前已知雀鲷科与隆头鱼科为此海域的优势鱼科，白天优势种则为变色雀鲷，4个测站都观察到每年鱼种的组成均略有改变，四测站Sorensen相似度约在60%~75%之间，差异主要来自稀有种。

They conta i ned full genes ORFs and proved to have been prolongated effectively. The result showed that the seqences of 14 genes were genes known previously and 6 genes were new .We separately chose one seqence from known and the other from unknown genes to make full-length cDNA annotation. Their code number was EST contig110 and EST contig133. We designed specific primers to amplify the two genes by RT-PCR, and then sequenced. The result was obtained as expected and proved that silico cloning genes was reliable.
