The SiO2 content of the dike swarms varies from 50.22% to 61.10% and they are basic-intermediate rock series, mainly basic. The Al2O3 content is generally higher than 15% and they are high aluminum basaltic rocks. The lower magnesium index (Mg#=42.77~62.28) and TiO2 content (0.97~2.41%) illuminate that they suffered magnesium-iron minerals' fractional crystallization and that they did not crystallize from original basaltic magma. The values of Na2O/K2O are all above 1, indicating lower K character. Chemically discriminated, these dike swarms are sub-alkaline rock series.

岩墙群的SiO2含量为50.22~61.10%，属于基性和中基性岩类，以基性为主；它们的A12O3含量普遍高于15%，属高铝玄武岩类；具有较低的镁指数（Mg#=42.77~62.28）及TiO2含量（0.97~2.41%），说明它们经历了镁铁质矿物的结晶分异作用，也指示它们不是由原始玄武岩浆结晶；Na2O/K2O都大于1，显示出低钾的特点；岩石化学判别，岩墙群岩石属亚碱性系列。

The results indicate that high reaction temperature and low space velocity can improve the conversion of alkanes oxidation reaction.

结果表明较高的反应温度和较低的空速有利于提高烷烃氧化反应的转化率。

The lower energy is because that the chemical bond between O〓 and M〓 has not formed completely, which cause by the higher covalency of Eu〓-O〓 bond in amorphous state. And the larger half width is caused by the disorder of sites.

这是由于在非晶态状态下金属氧键尚未完全形成，从而导致Eu〓-O〓的共价性较高，因此电荷迁移带处于较低的能量位置；而格位的无序性导致其光谱变宽。

Two key technical parameters, for prevention ofdiscoloration and proper hardness, were determined after a lot of experiments. Firstly, in order to reduce the cost of pretreatment and improved its quality in storage,low priced additivs, such as high maltose syrup and maltose dextrine, were tested inosmotic treatment in production of dehydrated cabbage.

首先，针对切割甘蓝脱水制品实际生产中预处理方案成本较高、品质不稳定等问题，采用成本较低的高麦芽糖浆和麦芽糊精进行预处理，以甘蓝渗透后的水分含量和固形物增加率为试验指标，研究了它们在渗透过程中的脱水性和渗透性，并同葡萄糖和乳糖作了比较。

Individuals with gene variants or haplotypes associated with low levels of dopamine beta-hydroxylase were more likely to attain cocaine-free urine with disulfiram in a study of heavy users of cocaine.

试验中投予disulfiram的严重古柯碱成瘾患者，如因个体基因变异或基因序列单体变异使体内产生较低的多巴胺贝他水解酵素，较容易得到没有古柯碱的尿液。

Typically because the eyelid skin is thinner and we tend to be on the lower side of the setting, so most patients to starting setting would be about 3, and we've certainly done peri-ocular as high as 4 joules per square cm.

因为眼部肌肤较薄，我们一般倾向于使用较低的设置，所以对大部分患者开始应用的设置为3 J/c m2，我们对眼周也使用过4J/c m2的设置。

We find that the carriers mobilities have high effects on them. When the majority carrier has the lower mobility, the carriers are easy to injection, transport, and the device efficiency has been improved.

场强分布及J-V关系受载流子迁移率影响较大，在器件中占主导地位的载流子应具有较低的迁移率，这样有利于载流子的注入和传输，发光效率可相应得到提高。

Chinese egrets showed significant preference for the ground under shrubs as their nest site, especially below shrubs higher than 50 cm, followed by sites inside shrubs lower than 64 cm and on top of tussocks.

黄嘴白鹭对巢位具有明显的选择性，优先选择在灌丛，尤其是那些相对较高的灌丛（高于50cm）下营巢，其次是较低的灌木（低于64cm）内部和草丛上。

Simulation results show that the beampattern of the concentric-ring array has lower sidelobe level compared with the circular array, and is effective in formation of adaptive nulling as well.

仿真结果表明，与均匀圆阵相比，双层圆阵的波束图有较低的副瓣电平，而且能够形成较深的自适应零点。

The nitrided layer formed on the surface of stainless steel consists of a nitrogen supersaturated austenite which is maintained to very high nitrogen concentrations and is of high hardness and good corrosion resistance.

与一般离子渗氮不同的是，这些新方法是在真空度较高、温度较低的条件下进行渗氮，可以充分地利用离子的能量提高渗氮效率。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
