不能测的

Be a card-carrying member Take a photo gray card along: It ' s much better for setting digital " white " balance, for accurate spotmeter exposures with slide film, for a photofinishing reference point for color-print film, etc.

带块灰板：相机的测光系统认为，物体都是反射率为18％的灰色。其测光就是按这个进行的。所以，拍雪景的时候，如果不加曝光补偿，就会拍出来发灰。带着灰板，就能准确测光。

Previously we use some impotents like thermograph detecting the temperature, but with the development of science and technology, the old means can not satisfy our needs, because the average thermograph must directly contact the measured substances, we must design some test equipments, which can measure the temperature without contacting the measured substances.

从前我们测温，用温度计等一些器具，但是随着科技的发展，这是远远不够的，因为普通的温度计必须直接接触被测物体，所以我们现在就要设计一些可以不接触被测物体就能得出其温度值的测试仪。

在规定了测量过程和分析样品类型时，不确定度能反映多种因素对检测结果的影响，不确定度能适用于该项目的测量值，有利于实验室间结果的可比性。

Signal peptide sequence was removed lest it couldnt be recognized by Bacillus subtilis, gene coding for mature peptide was ligated to downstream of sacB signal peptide sequence of pWB980 to form a new ORF and generate pWB980-LipA, gene coding for its chaperone was also amplified and ligated to the downstream of LipA to generate a secretion/expression vector pWB980-LipAB.thechaperone gene was sequenced and analyzed by multiple alignments, resulted showed that there were mutations of nucleotides(1～7) and amino acids (1～2) with the other reported genes.

为了防止枯草芽孢杆菌信号肽酶不能识别脂肪酶的信号肽，切除掉脂肪酶的信号肽编码序列，与枯草芽孢杆菌分泌表达质粒pWB980连接并与质粒上的SacB信号肽构成一个完整的开放式阅读框，获得重组质粒pWB980-LipA，因为该脂肪酶的活性表达需要一个特异性分子伴侣帮助折叠成有活性的构象，将脂肪酶分子伴侣基因串连到脂肪酶基因的下游，获得重组分泌表达载体pWB980-LipAB并且测序分析分子伴侣的基因序列和氨基酸序列并与其它报导的序列进行了比对，发现有1到7个碱基的差异和1到2个氨基酸残基的突变。

The chemical analysis of N, P and K in organic fertilizer is presented: sample is decomposed by sulfuric acid-hydrogen peroxide and prepared to be a solution. N can be determined by NC-2 model quick N analysis set, P by chinoline molybdic acid method and K by tetraphenylboron potassium, needless of spectral photometer and flame photometer, the method is available when the content of N, P or K is over 0.1% with desired accuracy and precision.

介绍用化学分析方法测定有机肥料氮、磷、钾的含量，即样品经硫酸-过氧化氢消化后，制备待测溶液，分取待测溶液用NC-2型快速定氮仪测定氮，用磷钼酸喹啉重量法测定磷，用四苯硼酸钾重量法测定钾，不需使用分光光度计和火焰光度计，适宜一般复混肥料厂采用，对含氮、磷、钾分别达0.1％以上的样品均可用本法测定，方法的准确度和精密度能满足生产的要求。

The key finding indicates that of the participants who received categorized WOM, those who received information displayed in a specific forum are likely to be more subjective on their purchase decisions than those who received information displayed in a integrated forum. Participants tend to be more secure, unconfused, and less likely to anticipate regret for their purchase decision when receiving with categorized information.

最后研究发现，当受测者所浏览的口碑资讯有受到分类，并以「个别讨论区」的方式呈现时，其「决策主观状态」会较无口碑资讯分类、以「综合讨论区」的方式呈现之组别要来的好，亦即有资讯分类，较能使受测者对决策感到确定、不困惑且预期未来发生后悔的可能性较低。

A new method is described for determining the microwave dielectric properties of solid materials,for example agricultural products,mineral,of known densities from the dielectric properties of pulverized samples measured by employing the short circuited waveguide principle at a few different bulk densities.

Therefore, non-contact temperature measurement technique becomes the development trend of high temperature measurement and will be used more and more widely in measuring the temperature field of weld arc and pool.

非接触测温主要有辐射法和干涉法，由于测温元件不与被测物接触，不会破坏被测物的温度场，通过与数字图象处理技术相结合，能实现温度场的快速、实时测量，全面、形象的反映温度场的动态变化，因此成为高温测量技术的发展趋势，在焊接熔池和电弧温度场测量中得到越来越多的应用。

Total RNAs from KAx-3 cells and AK127 cells(developed for 14h) were isolated. After the reverse transcription and PCR reaction, two distinct differential fragments were acquired., fragment A was from KAx-3 cells and fragment C was from AK127 cells. After retriving and reamplifying the differentially expressed fragments, white-blue plaqueselection, the fragments were purified. Northern blot proved that fragment A was from KAx-3 cells and fragment C was from AK127 cells. The results of sequencing and researching for NCBI database have been showed: part sequence of fragment A shows 91% similarity to the gene encoding DhkA, 92% similarity to the gene encoding DhkF, 91% similarity to the gene encoding STATc, 97% similarity to the homoeobox gene encoding protein. These genes play important part in controlling cell differentiation and cell proportion in Dictyostelium discoideum.

本研究通过提取盘基网柄菌发育14小时的野生型KAx-3细胞和突变型AK127细胞的总RNA，运用mRNA差异显示法分离出了两条明显的差异表达片段，其中片段A来自野生型KAX-3细胞，片段C来自突变型Ak127细胞；并通过凝胶回收差异片段、对差异片段进行再次PCR、蓝白斑筛选克隆、提取质粒、酶切电泳纯化差异片段；接着进行Northern杂交的结果表明，片段A只与野生型KAx-3细胞的总RNA有杂交信号，片段C只与突变型AK127细胞的总RNA有杂交信号，这就排除了差异片段假阳性的可能；最后通过测序，搜索NCBI BLAST数据库发现：片段A的小部分序列与编码组氨酸激酶DhkA基因中一段序列的相似性高达91%，与编码组氨酸激酶DhkF基因中的一段序列相似性高达92%，与编码STATc蛋白基因的一段序列相似性达91%，以及与编码同源框蛋白的基因中的一段序列相似性达97%，这些基因在盘基网柄菌细胞分化和细胞比例调控过程中起着相当重要的作用，这些数据进一步说明了突变细胞不能完成发育的原因。
