Two kinds of water-soluble biomimetic chitosan derivatives with a phosphoramide linkage between glucosamine and choline were prepared through Atherton-Todd reaction under the mild conditions, including zwitterionic phosphorylcholine bound chitosan and acetyl-phosphorylcholine bound chitosan with positive charge. The interaction between chitosan derivatives and calf thymus DNA were inversigated by UV alsorption spectra and circular dichroism spectra.

采用Antherton-Todd反应制备了两种水溶性的磷酰化壳聚糖仿生衍生物：两性的N-磷酸胆碱磷酰化壳聚糖和带正电荷的N-乙基磷酸胆碱磷酰化壳聚糖，并用紫外吸收光谱和圆二色光谱研究了两种胆碱磷酰化壳聚糖衍生物与小牛胸腺DNA的相互作用。

For carbon dioxide, the two analyzers could be in a single unit such as gas chromatograph or they could be separate units.

对于二氧化碳，两个分析仪可以在单独的装置中，例如气相色谱，或者两个分析仪是独立的装置。

Two methods of distillation crystallization method and gas chromatography to determine the naphthalene content in coal tar oil were introduced.

介绍煤焦油中萘含量测定的两种方法：蒸馏结晶法和气相色谱法，对两种方法的优缺点及分析结果进行了对比。

Appling gas chromatography method to determine single layer's output and water cut of commingle producing well enriches commingle production technology. This application not only can be used to determine single layer's output, but also water cut. This technology must play important role to develop Putaohua and Fuyu reservoir effectively.

气相色谱技术用来确定合采井分层产量、含水的应用技术丰富了葡扶合采技术，其应用不仅可以确定合采井分层产量，而且可以定性确定两套油层的含水，对研究两套油层的动用状况必将发挥重要作用。

First, to isolate the total RNA both in hypha and yeast phase of Malasesiza furfur, Then reverse them to cDNA and found a different cDNA library with Malasesiza furfur in hypha phase by Subtractive Hybridization; At last, clone and sequencing the gene fragment on differential expression of Malasesiza furfur in hypha phase.

首先提取糠秕马拉色菌两相细胞的总RNA；然后逆转录生成两相细胞cDNA，运用消减杂交技术获得菌丝相细胞差异表达的cDNA，并建立差异文库：最后对差异cDNA片段克隆测序。

After the discussion of the constrain condition for Bose-Einstein statistics in NC Phase space, the Hamiltonian operator of the two dimensional charged harmonic oscillator in external electric field was discussed.

在所考虑的相空间变量的对易关系中包含了坐标－坐标和动量－动量两个方面的非对易性；讨论了非对易相空间中服从玻色－爱因斯坦统计的粒子的连续性条件；在所给出的相空间变量的对易关系中包含了空间－空间和动量－动量两个方面的非对易性。

As soon as the two of them emerged from the dense forest, they saw two iron-gray horse-like animals with long pointed ears, tied to a tree.

两人刚走出密林，就见到两只似马非马，耳朵尖长，色作铁灰的动物，系立在一棵树下。

Take consider of the comparison of the light efficiency and the color rendering index we can find that: one piece of 1000W plasma lamp can equivalence to 2 pieces of 1000W metal halide lamp( no considering the light declining in ceramics metal halide lamp running ), and the lifetime of plasma lamp is 2 times to the metal halide lamp, so as a total by considering the lifetime and light efficiency indexes the one shot cost of metal halide is : 2×6500×2=26000YRMB, So we can find that the plasma lamp can save us 20500YRMB in the one shot cost.

根据两款灯发光效率和显色性的工程照明指标相比较得出：1个1000W的等离子灯相当与2个1000W金卤灯的照明效果（不计陶瓷金卤灯的后期光衰），而等离子灯的寿命是金卤灯的2倍，综合寿命和照明效果两项指标，在一次性投入上，金卤灯是2×6500×2=2.6 万元，由此可见，等离子灯的一次性投入比金卤灯节省2.05 万元。

The reason is that , because the peak can not be separated individually in two, acceptable baseline peaks by using the USP method they forcebly marked it in two peaks by minimising the height visuality to show two separate peaks less than 1

原因是因为色谱峰不能分成两个独立的峰，通过USP方法手动积分，以不超过1％的比例减小峰的视觉高度，强行将此峰标记为两个可接受的基线峰。

Two lamps dating from the seventh century were found, as also oil lamps common in the 4-6th centuries. Two rooms yielded fragments of glass vases and even two whole vessels with a cylindrical neck and a bulbous body. Two samples of dual face-rouge phials were found, one containing a bronze application stick. Such objects have been brought to light in a number of Byzantine tombs. Besides, items in bronze and iron have been retrieved: bracelets, rings, clasps and others.

在这里发现了第7世纪的二盏灯和在4到6世纪常见的油灯，另外在两个房间里有玻璃花瓶的碎片和两个有圆颈和圆体的容器，更找到了两个胭脂色的小瓶子，其中一个包含了铜棒，像这样类似的物品在许多拜占庭的墓穴中被发现，此外，也有许多铜制和铁制的物品，如手镯、耳环、钩子等等。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
