"Hydraulic safety valve" is widely used in hydraulic power systems and hydraulic equipment of safety devices, pressure devices can be limited, is a special valve, which is different from the conventional valve, the traditional use of mechanical valves metal spring as a driving force, can only be limited to low pressure, encountered more BALANCING VALVES than 10Mpa pressure limit pressure can do to increase the volume of pressurized design, the traditional role of the high-pressure valves and high pressure hydraulic power systems and hydraulic equipment The limit pressure of necessity is bulky and complicated structure, difficult to manufacture large, high production costs; in the course of the fatigue of metal spring parameters change fluctuating pressure limiting Ambassador to regular revision to ensure the normal use.

&气动液压安全阀&是目前广泛应用于液压动力系统和液压设备中的安全装置，也可以作限压装置，是一种特殊的阀门，它不同于传统的阀门，传统阀门用机械金属弹簧为动力，只能限中低压力，遇到超过10Mpa以上的压力限压，闸阀只能做加大体积的增压设计，因此传统阀门作用于高压和超高压的液压动力系统和液压设备的限压时必然体积笨重，结构复杂，制造难度大，产品成本高；在使用过程中金属弹簧的疲劳变化大使限压参数波动大，要经常调整才能保证正常使用。

"Hydraulic safety valve" is now widely used in hydraulic power systems and hydraulic equipment in the safety device could also serve as limited pressure device, is a special valve, unlike conventional valves, conventional valves with mechanical metal spring as a driving force, can only be limited to low pressure, the pressure encountered over more than 10Mpa limit pressure can do to increase the volume of the Safety Overflow Valve booster design, the traditional role of the high-pressure valves and high pressure hydraulic power systems and hydraulic equipment The limit pressure of necessity is bulky and complicated structure, difficult to manufacture large, high production costs; in the course of the fatigue of metal spring parameters change fluctuating pressure limiting Ambassador to regular revision to ensure the normal use.

随重金属胁迫浓度的增加，水稻籽粒萌发期的Q一淀粉酶活性先上升后下降，重金属胁迫能显著抑制釉稻和杂交稻p一淀粉酶活性，但低浓度的重金属胁迫对粳稻压淀粉酶活性产生诱导作用。

The paper also introduces the ingredients of some typical nobel metal - rare earth metal catalyst.

给出了几种典型贵金属－土金属催化剂的配方。

Professional silk screen etching: stainless steel signs, letter box, mechanical panel, ti-gold signs medal, copper signs nameplate, PVC electric nameplate, metal highlight signs, brushed aluminium oxidation panel, blasting panel, acrylic show stand, acrylic medal, metal high grade name card, and VIP card.

本发明提供了一种形成钝化金属层的方法，所述钝化金属层可以在随后暴露于含氧环境时保持下方金属层的性质和形貌。

Anodising reaction proceeds in the sequence of growth of porous anodic alumina when the aluminum layer is consumed up to the underlying metal, and the growth of metal oxide under the bottoms of the alumina pores occurred simultaneously.

以电化学的方式在阳极产生氧化铝孔洞的同时，底层的金属同时被氧化而在孔洞底端成长出奈米点。以草酸、硫酸和磷酸不同的电解液和不同施加电压下观察奈米点的阵列。

The kinetics of reconstitution of apoacylase with either 〓 or 〓 and the inactivation of the 〓 reconstituted enzyme by 1, 10-phenanthroline has been studied by following the substrate reaction continuously in presence of the metal ion or OP respectively. Although the native 〓-containing and the 〓-reconstituted enzymes have closely similar Michaelis constants and maximal velocities, the kinetics for both the inactivation by OP and the reconstitution of the apoenzyme with the metal ions differs considerably.

虽然钴重组的氨基酰化酶与天然含锌的氨基酰化酶在催化活性上比较相近，但两种酶在去金属失活动力学机制以及去金属失活的氨基酰化酶与两种金属离子重组复活的动力学过程均存在较大的差异，说明锌在氨基酰化酶中的作用比较复杂，并不能完全由钴替代。
