摘要： 泰珂洛公司推出的用于內徑槽加工的AddInternalCut高精度可轉位工具系統,該系統采用革命性的四切削刃刀片,可用于直徑小至10.5 mm的內孔槽加工。使用可轉位刀片進行內孔切槽會受其孔直徑的限制;因此,傳統的小孔內孔切槽刀片只能有一個或最多兩個刃口。

摘要： 近期,泰珂洛擴充了設計用于保證低切削力的TCL18型斷屑槽,這是TetraMini-Cut四角切槽刀片最新增加的槽型,可用于各種材料包括鋼、合金鋼、不銹鋼和耐熱合金的切槽加工。

摘要： 相信很多攝影師朋友對于照片調色的流程以及工具(PS、LR)的使用已經了然于胸,做到了手到擒來。但是碰上視頻調色就顯得有點“手足失措”,不知道如何下手,對于不同軟件的調色工具又相對陌生。今天筆者就以macOS系統下最“好用”的視頻編輯軟件Final Cut Pro X為例,實例講解一下筆者是如何進行視頻調色的,希望可以幫助還未掌握Final Cut Pro X調色的讀者朋友們。

摘要： 意義與目的:與標準的手工結腸肛管吻合+轉流性回腸造口+后續回腸造口還納術相比,低位直腸癌Turnbull-Cutait分期拖出式手工結腸肛管吻合術在術后并發癥發生率方面似乎可提供獲益。本文擬比較直腸癌行超低位直腸前切除后Turn-bull-Cutait拖出式手工結腸肛管吻合術與標準的手工結腸肛管吻合+轉流性回腸造口術的術后30天和術后1年隨訪結果。

摘要： Floriculture is a promising segment of Brazilian agriculture. The ornamental sunflower (Helianthus annuus L. cv. Folded Sungold), also known as dwarf sunflower, in addition to being used in gardens can be marketed as cut flower or vase. The sunflower represents a great alternative for small producers because it requires little space, has easy handling and short cycle, besides providing greater economic return. In this context, we aimed to evaluate the development of this culture submitted to different levels of saturation per base, combined with the incubation time of the limestone. The experiment was carried out in a greenhouse at the Federal University of Mato Grosso-University Campus of Rondonópolis. A randomized block design with factorial scheme 6 × 2 was used, with six levels of saturation per base: 0, 20%, 40%, 60%, 80%, 100%;and two incubation times: 0 and 30 days, resulting in 12 treatments with four replicates, totaling 48 experimental units. Each plot consisted of a plastic polyethylene vessel with a capacity of 1.2 dm−3. The following variables were analyzed: Height of the floral stem;number of leaves, diameter of chapters;root volume;fresh mass of leaves;fresh mass of floral stems;fresh mass of chapters;fresh root mass and chlorophyll index (SPAD). Data were submitted to analysis of variance by the test F at 5% probability of error. The qualitative factors were submitted to the Tukey test and quantitative factors to the regression test, both with a 5% probability of error. Basal saturation levels of 80% and 100%, in the treatment with incubated soil, provided higher quality of inflorescence for commercialization purposes.

摘要： To enhance link capacity of a wireless link one or more repeater is used between the sender and the receiver. Recent literature deals with multiple parallel links to enhance throughput instead of conventional single path. In case of a multidirectional and multi-hop wireless network, the selection of link of maximum signal to noise ratio (SNR) does not guarantee the maximum throughput. In this paper, we use augmenting path of Ford-Fulkerson algorithm in detection of maximum flow from sender to receiver. To reduce the process time at the sending node, minimum-cut theorem is used to determine maximum flow like power flow of previous work. Using the maximum flow algorithm, we obtain the capacity of multi-hop wireless link higher than the conventional theorem. The concept of the paper is applicable in MANET (Mobile Ad-hoc Network), WSN (Wireless Sensor Network) and CRN (Cognitive Radio Network).

摘要： A oilfield was an oil reservoir with strong bottom water in offshore, the water cut was as high as 96%. In the high water cut stage, the most effective way of increasing oil production was to extract liquid and increase oil. The processing capacity of oilfield fluid was limited by the conditions. By using Petrel-RE-2017 software, combining reservoir engineering and percolation mechanics methods, this paper analyzes the effect of large-scale liquid pumping, expand coverage and shut-in coning in oil reservoirs with bottom water, and formulates the adjustment strategy of single well production structure of the whole oilfield. It was confirmed that large-scale liquid production can expand coverage and shutting down well can reduce water cut. It can provide reference and guidance for oil field with strong bottom water when it encounters bottleneck of liquid treatment capacity.
