均差

The three types of dolomite have similar strontium content with higher ~(87)Sr/~(86)Sr ratios to some extent than that of the coeval seawater.The difterenee of distribution coefficient of Sr in calciteand dolomite is the most important control factor on the strontium content in dolomites.

三种类型白云岩具有类似的锶含量，但其(87)~Sr/(86)~Sr 比值均不同程度地高于同期海水值，锶在白云石和方解石中分配系数的差别是影响白云石化过程中白云石锶含量最为重要的因素。

系列数字地震检波器主要用于石油勘探，具有宽频带和较高的假频，各参数指标容允差均在5%以内。

Objective Study the indoor ground free flea control method to prevent occurrence and epidemic of mouse transmission diseases.

化学杀虫剂杀灭地面游离蚤，均以有机磷或拟除虫菊酯类杀虫剂的单一用药为主〔1，2〕，但在实际工作中发现，单一用药灭蚤效果很差。

Adding transition metals into the TiN films by arc ion plating (1) The hardnesses of theN films are higher that that of the TiN films, proving that the alloy hardening effect is a common phenomenon;(2) The structures of the alloyed films are determined by the added element properties such as covalent radius, electro negativity, free energy and lattice parameters of the MN compound;(3) theN film consists of a mixture of multi phases with high hardness but quite brittle, while the other MN films are composed of single phase with the fcc TiN structure and their hardesses, functions of the added amounts of the elements, manifest always a maximum at a certain M percentage.

一、将过渡金属M用电弧离子镀方法添加于TiN薄膜中：1。N薄膜硬度均高于TiN薄膜硬度，合金强化效应普遍存在；2。薄膜相结构决定于添加元素M的周期律信息，包括M的共价半径、电负性，及MN化合物的自由能、晶格常数等；3。N为多相混合结构，薄膜硬度高，但韧性差；其它N的相结构为TiN类型的单一fcc结构，薄膜硬度随M添加量变化并出现峰值；4。

However, the Sheshan not "Tiger" blessed, Woods set off two HSBC Champions, are to finish runner-up: HSBC Champions in 2005 the first year of his three shots lost to England players David Howell; 2006 Yang Yong-eun was dark horse pick dismount.

然而，佘山并非&老虎&的福地，伍兹两次出征汇丰冠军赛，均以亚军作收：2005年汇丰冠军赛元年，他以三杆之差不敌英格兰球员大卫·豪威尔；2006年被黑马梁容银挑下马。

The test data show that the loose scope of slope rock mass is wide, the rock mass of surface and interior of slope is from super crash to crash , the integrality of rock mass is very awful. The research result provides the reference for slope shape optimizing .

测试表明，边坡岩体的松弛层范围较大，边坡及边坡内部的岩体均为极破碎-破碎岩体，岩体完整性非常差，研究结果为凹陷露天矿边坡形状优化提供了依据。

The chemical structure, thermal properties and liquid crystalline character of liquid crystalline ionomers were analyzed with FT-IR, POM, DSC and WAXD, the result shows the ionomers have the same structures-nematic texture-with the previous polymers before ion monomer was added.

利用红外光谱分析对其结构进行了表征，采用偏光显微镜、示差扫描量热仪和广角X射线衍射等手段对其液晶性能进行了表征。结果表明：各离聚物与原没有加入离子单体的聚合物具有相同的织构，均为向列型液晶。
