Methods 135 maintenance hemedialysis cases were divided into well-controlled hypertension group(61cases)and poorly-controlled hypertension group(74 cases). BMI, urine volume of residual renal, erythropoietin dosage, time of maintenance hemodialysis, change of body weight during hemodialysis intermission, hemodialysis mode, KT/V values, dry body, hemachrome concentration were recorded. Singer-variable analysis and multi-variable Logistic regression analysis were performed to examine the risk factors associated with poorly-controlled hypertension.

But it seems impossible to suppose that an agent could change the electrical resistance of a physical system without expending energy in the process, for to do this would necessitate changing the physical structure of the system, and that implies changing the positions of bits of matter on which forces are acting (think of turning the knob on a rheostat or variable resistor: one must expend energy to do this).

但是似乎不可能假设一个人能够改变物理系统的电子阻力而没有在这个过程中消耗能量，因为这样做会必然改变系统的物理结构，这会导致物质的the positions of bits的改变，在其中力起了作用。（考虑可变电阻器的按钮，做这个事情是要消耗能量的。
