Abstract］ Objective To study the synthesis and antibiosis activity of the complex La with chlorogenic acid.

目的 研究金属镧与绿原酸配合物的合成及抗菌活性。方法通过元素分析、红外光谱、热重分析和化学分析，确定配合物的组成为［La（C16H17O9）3］·2H2O。

The main heat-proof and temperature-preserving covers are Silurian and Ordovician argillite of Gaozaitian Formation and Meitan Formation.The main thermal reservoir layer is Cambrian carbonate rock of Loushanguan Group.The aquatic chemistry of the hot ground water and drilling data indicate that the reservoir depth ranges from 1300 to 2500m and the geothermal gradient from 2.44 to 2.84℃/100 m. It is pointed out that there may exist another geothermal field in the plunging part of the east limb of Wudang Anticline.Some suggestions are made about the development and protection of the geothermal field.

其主要隔热保温盖层为志留系高寨田群(S1g)和奥陶系湄潭组(01m)泥页岩，主要热储层为寒武娄山关群(∈2-3ls)碳酸盐岩，根据地下热水水质化学成份特征及钻探资料，其深度为1300-2500 m，地温梯度2.44-2.84℃/100 m；指出乌当背斜东翼倾伏端有另一地热田存在可能性；以及对地热田研究开发、保护的意见。

Orion KL hot molecular core is known to be rich in organic molecules; the brightness ( 105L ) and proximity ( 450 pc) of Orion KL make it a primary target for molecular line search and astrochemistry study.

猎户座KL热分子云核是个已知富含有机分子的天体，它的亮度(~ 105 Lsun)以及相对於太阳如此近的距离(~ 450 pc)非常适合我们来寻找在太空中尚未被指认出来的重要分子以及做天文化学上的研究。

GUP decomposed to guanidine polyphosphate GPP(at about 180℃), then to ammonium polyphosphate APP (at about 285℃), and in turn to polyphosphoric acid PPA (at about 385℃). The pyrolysis process of basswood was changed by the treatment of FRW or its components. It was discovered that BZ lose weight at quite lower temperature (165℃) than UZ did, and this may attribute to the catalytic effect of B on the pyrolysis of basswood to form char.

FRW阻燃剂及其组分均改变了木材的热解途径，其中，观察到BZ在较低的温度下（约165℃）即发生明显的失重，说明硼酸的阻燃机理除了传统理论认为的物理覆盖作用以外尚存在化学催化作；GUP 处理使紫椴木材的最大失重速率温度从375℃降低到314℃，同时失重率也显著降低，而成炭率升高；FZ的失重率低于其他处理材。

In the present paper,ZnS:Ag nanoparticles were prepared with simple chemicals by hydrothermal method.XRD patterns indicated that the products have cubic zinc blende crystal structure.

以简单的化学试剂和实验过程，采用水热法制备出ZnS：Ag纳米发光材料。X射线衍射结果表明，产品均为结晶良好的ZnS立方闪锌矿结构。

Compounds with bond energy of 180 -260 kJ/mol were considered as good initiators for initiated cracking of n - heptane and nitroethane was the best in the used initiators.

从化学键能的角度筛选了引发剂，键能为180-260kJ／mol的化合物对正庚烷热裂解有较好的引发效果，其中硝基乙烷的效果最明显。

According to this point it has good ability to absorb neutron and resist eradiation.Because of their high hardness and strength, excellent wear and corrosion, low density, low friction coefficient good self-lubricate and high temperature properties both silicon carbide and boron carbide components have been widely used in many industries.

由于碳化硼中的B14中子缺失，它还具有较大的热中子俘获截面，具有极好的中子吸收和抗辐射性能，由于其具有耐高温，耐酸碱腐蚀，高强度，高化学稳定性，比重轻，半导体等特点而成为众多行业的首选材料。

主要产品有进口意大利皮糠纸、国产热溶胶前后套，定形布、补强材、坎培拉弹力化学片、仿里皮、中底布、乳胶、海绵、超细纤维等鞋用材料。

The elastomer material of most rubber seals (Section 6.3.2) is acrylonitrile butadiene rubber also known as nitrile rubber or buna N. For seals which are exposed to special thermal or chemical conditions, more expensive rubber grades may be required.

大部分的弹性体材料生产橡胶密封6.3.2丙烯腈顺丁橡胶也被称为丁腈橡胶或buna是：暴露于特别热或化学条件，更昂贵的橡胶级别也是可能被要求的。

So the disposal technics of physical calefaction cooperating with chemical medicament is feasible used to disposing the BSL-3 laboratorys wastewater including of microbial pathogen.

因此，物理湿热与化学药剂协同的处理工艺对于BSL—3实验室废水的消毒灭菌处理切实可行。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
