采用分離技術,建立了測定注射用頭孢孟多酯鈉中碳酸鈉的方法。篩選了溶解溶劑,考察了樣品預處理時干燥溫度、干燥時間及真空度對測定結果的影響,并進行了優化。樣品在110℃、14kPa絕對真空度條件下減壓干燥4小時后,用二甲亞砜超聲溶解,過濾,水溶解濾渣,用鹽酸滴定,實現了碳酸鈉的準確測定。在80%、100%、120%三個添加水平下,碳酸鈉的加標回收率在96.0%~96.8%之間,相對標準偏差為0.4%;日內精密度和日間精密度的相對標準偏差分別為0.6%和0.8%。實際樣品分析結果表明,該方法簡單、快速、準確,可用于注射用頭孢孟多酯鈉中碳酸鈉含量的測定。
Separation technique was used to establish a new method to measure content of sodium carbonate in cefamandole nafate for injection. The solvent for dissolution was optimized, and the influences of drying temperature, drying time and vacuum degree on the results were explored. After drying at absolute vacuum (110°C, 14 kPa) for 4 h, the sample was dissolved in Dimethyl sulfoxide (DMSO) by ultrasonication, and filtered. Then, the filtered residue was further dissolved in water, and titrated using HCl, which accurately measured the content of sodium carbonate. Under addition levels of 80%, 100% and 120%, the spiked recovery rate of sodium carbonate was between 96.0% and 96.8% with relative standard deviation (RSD) 0.4%. The RSDs of intra-day precision and inter-day precision were 0.6% and 0.8%, respectively. The results indicate that the method is simple, fast and accurate, which can be used to measure the content of sodium carbonate in cefamandole nafate for injection.

從歷史的角度來看,當整個社會的產能不足的時候,競爭的壓力大多集中的需求方,人類往往通過戰爭這種方式來進行資源的再次分配。當整個社會的產能過剩的時候,競爭的壓力就從需求方轉移到供給方了,供給方的競爭也就是我們今天所說的公司與公司之間的競爭。
競爭從需求方轉移到供給方的過程就是我們所說的風口期。在風口期,由于市場需求沒有得到滿足,公司最主要的職責就是生產出合格的產品,在這個時期企業的擴張是沒有上限的,全力的擴張往往能夠形成很大規模的公司。
當風口期過了以后,也就是開始出現產能過剩的時候,公司就不得不面臨一個問題:如何讓消費者選擇我而不是我的對手?公司運營的載體是品牌,公司之間的競爭就是品牌之間的競爭。
From a historical perspective, when the production capacity of an entire society is insufficient, most of the pressure for competition is concentrated on the demand side, and mankind often redistributes resources through warfare. When there is excess production capacity for an entire society, the pressure for competition shifts from the demand side to the supply side. Supply-side competition is what is called today competition between companies.
The process of shifting competition from the demand side to the supply side is what we call the "venting period." During the venting period, because market demand has not been met, the main responsibility of companies is to produce qualified products. There is no upper limit to the expansion of the industry during this period. All-out expansion can often lead to the formation of very large-scale companies.
When the venting period is over, then production capacity surpluses begin to emerge, and companies must answer the question: "How do I get consumers to choose me over my competitors? The vehicle through which a company operates is its brand. Competition between companies is actually competition between brands.
