变化范围

All pregnant women face tremendous physical changes ranging from weight gain,bloatedness,generalised swelling to psychological changes caused by hormonal changes.Most women enjoy being pregnant but the face is many women who are happy about being pregnant and who want their babies dislike or even hate the unpleasant pregnancy symptoms.

Based on the absorbance change of indicators with the concentration of hydrogen ion released from the enzyme-catalyzed reaction, a convenient colorimetry method is established for the assay of acidic phospholipase 〓 and glycogen phosphorylase b Brilliant yellow and bromothymol blue are chosen as indicators for assays of acidic phospholipase 〓 and glycogen phosphorylase b by following the absorbance changes at 495 nm and 615nm respectively The method is simple, sample-saving, sensitive and valid for a wide range of enzyme concentrations.

为了研究糖原磷酸化酶的激活动力学和酸性磷脂酶〓的复性过程，我们根据酶催化反应中释放氢离子浓度的变化引起相应的指示剂的光吸收发生变化的原理，建立了一种简捷的比色法，用于测定酸性磷脂酶〓和糖原磷酸化酶b的活性。选用亮黄和溴麝香草酚兰分别作为酸性磷脂酶〓和糖原磷酸化酶b测活的指示剂，在495 nm和615 nm处检测二者的光吸收值的变化，可以测定酶活。本方法的优点是，可在比较宽的酶浓度范围内进行活力测定，而且操作简单、节省样品、灵敏度高。

The PL spectra of the series Zn_xCd_(1-x)S nanocrystals have been revealed, from which we can find optical properties variation of the samples.

光致发光谱分析表明，随着Zn含量的变化，样品的发光峰位发生着规律性变化，我们可以通过改变Zn_xCd_(1-x)S中成分含量变化在一定范围内调控样品的发光性能。

In addition, the blank holding force that is required to avoid wrinkle and rupture during conical part deep drawing is researched. The necessity of reasonable blank holding force in pressing is expounded. From the view of mechanical analysis, the wrinkle critical condition of side-wall is derived for the first time by the stress state of side-wall, the main deformation region on blank. According to the critical condition of plastic instability for flange, side--wall, corner of punch on blank, The blank holding force in conical part deep drawing is divided into four different regions within its forming figure. The basic principle of reasonable blank holding force during stamping is summarized and provided. The mathematical model of reasonable blank holding force that avoids the wrinkle and rupture is established and verified by the finite element numerical simulation and the grid experiment method. The result shows that it is accurate and reliable.
